Yintoni kanye kanye i-DIN Rail Busbar Terminal Block?
Ibhloko yesiphelo sebhasi ye-DIN rail sisixhobo sokudibanisa umbane esilungiselelwe ukusasazwa kombane — hayi iingcingo zesignali, hayi iisekethe zolawulo, kodwa ukuphathwa kwamandla okwenyaniIfakwa kwi-DIN rail eqhelekileyo ye-TS-35 (35mm ububanzi) kwaye isebenzisa i-copper busbar edibeneyo ukusasaza umbane oyintloko ongenayo kwiisekethe ezininzi zamasebe eziphumayo. Uphawu oluchazayo olwahlula ibhloko yesiphelo sebhasi kwibhloko eqhelekileyo yokutyibiliza yireyile yokuhambisa ekwabelwana ngayo: i-conductor enye enkulu engenayo inika amandla i-copper busbar, kwaye yonke indawo yesiphelo kuloo busbar ifikelela kwi-potential efanayo.
Kwifektri yethu, senza ezi bhloko ngokwee-configurations ukusuka kwiindlela ezimbini ukuya kwiindlela ezingama-20 — oko kuthetha ukuba i-feed enye ephambili engenayo inganika amandla ukuya kuthi ga kwiisekethe ezingama-20 zamasebe ezahlukeneyo ukusuka kwi-single compact DIN rail footprint. Oku kubaluleke kakhulu ekwakheni iipaneli zehlabathi lokwenyani kuba Iyasusa imfuneko yeebhloko zokusasazwa kwamandla ezahlukeneyo, inciphisa ixesha lokufakelwa kweentambo zephaneli malunga ne-40-60% xa kuthelekiswa nezisombululo ze-jumper ezisuka kwisiphelo sendlela ukuya kwisiphelo sendlela..
Ukuqonda i-1000V kunye ne-200A Ratings: Oko Kuthethwa Ngamanani Ngokwenene
Xa sithetha "nge-1000V rating" kunye "nomthamo we-200A," sibhekisa kwiiparamitha ezimbini ezahlukeneyo zoxinzelelo lombane - kwaye ukuzibhidanisa yimpazamo endiyibonileyo iinjineli ziyenza amaxesha amaninzi kwiminyaka yam eli-15 kweli shishini.
Uvavanyo lweVoltage (1000V): Umngeni woKhuseleko
Ireyithingi ye-1000V ixhomekeke kakhulu ekugqibeleleni kobushushu, kungekhona kumthamo womqhubi. Ngokwe I-IEC 60947-7-1, iibhloko zesiphelo ezenzelwe iisekethe ezifikelela kwi-1000V AC kufuneka zigcine umgama omncinci wokuqhekeka we-8mm kunye nomgama wokuphuma we-5.5mm phakathi kweepali ezikufutshane - kwaye le migama ilinganiswa kwindawo embi kakhulu yokunyamezelana. Ngenxa yokuba izinto ezihlala apho (ngesiqhelo yi-nylon ye-PA66 ene-30% yefayibha yeglasi eqinisiweyo) kufuneka zimelane ne-voltage ye-impulse elinganisiweyo ngaphandle kokulandelela okanye ukuqhekeka, sisebenzisa i-UL94 V-0 polyamide ethintela ilangatye ene-comparative tracking index (CTI) edlula i-400V.
Kumgca wethu wemveliso, ibhloko nganye elinganiswe nge-1000V ivavanywa amandla e-dielectric e-2200V AC imizuzwana engama-60 — oko kungaphezulu kwephindwe kabini kune-voltage elinganisiweyo, kuba Ubushushu kufuneka buhlale buphila kwii-overvoltages zexesha elifutshane eziveliswa ziindawo zoshishino zokwenyani imihla ngemihla ukusuka ekuqaliseni iimoto, ekutshintsheni i-contactor, kunye nokusebenza kwebhanki ye-capacitor..
Uvavanyo lwangoku (200A): Ingxaki yoLawulo loBushushu
Ireyithingi ye-200A ayiqondwa kakuhle ngokufanayo. Luphawu lobushushu, alungomda womzimba wokuhamba kwee-electron. Kwi-200A continuous current, ilahleko ze-I²R kwi-16mm² copper busbar zivelisa malunga ne-12-15 watts zobushushu ngemitha nganye - kwaye ngaphakathi kwiphaneli yokulawula evaliweyo kwi-40°C ambient, olo bushushu kufuneka luye ndaweni ithile. Yiyo loo nto ke kufuneka ukuba bube sendaweni ethile. Uvavanyo lwangoku lwebhloko yesiphelo luhlala lulinganiswa kubushushu obuthile (ngesiqhelo yi-40°C ngokwe-IEC 60947-7-1) kwaye luthatha i-convection yomoya ekhululekileyo ejikeleze ibhloko.
Isayensi yezinto zeBusbar: Kutheni iCopper ibaluleke ngaphezu kokuba ucinga
Ndifuna ukuthetha ngokucacileyo apha: Izinto zebhasi ezikwibhloko yesiphelo sendlela yeyona nto ibalulekileyo echaza ukusebenza kwayo kwihlabathi lokwenyani — kwaye yindawo apho abavelisi abanciphisa iindleko banciphisa khona iindleko.
Kukho izinto ezintathu zebhasi ezifumaneka rhoqo kwimarike, kwaye zisebenza ngendlela eyahlukileyo kakhulu:
| Izinto zeBhasibha | Ukuqhuba (% IACS) | Ukuqhuba kwe-Thermal (W/m·K) | Amandla okuThamba (MPa) | Isalathiso seendleko |
|---|---|---|---|---|
| I-Electrolytic Copper (C11000) | 99.9% | 391 | 220-250 | 100 |
| Ibrass (C26000) | 28% | 120 | 300-400 | 55 |
| Ubhedu oluGcwe ngeTin | 99.5% (umphezulu) | 385 | 220-250 | 115 |
Sisebenzisa i-C11000 electrolytic copper kuphela kuzo zonke iibhloko zethu ze-busbar terminal blocks zethu ezine-200A. Kutheni? Kuba Iibhasi zebrass ezisebenza kwi-200A ziya kufikelela kubushushu bomphezulu obuphezulu obumalunga nama-25-30°C kuneebhasi zebrass ezifanayo - kwaye loo mahluko wobushushu uguqulela ngokuthe ngqo kuxinzelelo oluphantsi loqhagamshelwano kwizikhululo zezikrufu, amazinga aphezulu e-oxidation, kunye nobomi obufutshane bemveliso. Umahluko wexabiso phakathi kobhedu nobhedu kwibhloko yebhasi yeendawo ezili-10 eqhelekileyo imalunga ne-$0.80-1.20 kwizinto ezikrwada — andifuni ukuvumelana apho.
Uluhlu lweeNtambo kunye neTekhnoloji yoQhagamshelo: Ukudibanisa iiConductors kunye nomthamo
Uluhlu lokwamkelwa kweentambo zebhloko yesiphelo sebhasi ye-200A ludla ngokuqala kwi-6mm² (AWG 10) ukuya kwi-70mm² (AWG 2/0) kwicala eliphambili lokufaka, kunye neeterminal zesebe ezamkela i-1.5mm² ukuya kwi-16mm² (AWG 16 ukuya kwi-6). Olu luhlu olubanzi lokwamkelwa alukho ngengozi — lubonisa inyani yombane yokusasazwa kwamandla: i-feed ephambili ithwala i-200A epheleleyo (yiyo loo nto iphezulu kwi-70mm²), ngelixa iisekethe zamasebe ngazinye zinokutsala naphi na ukusuka kwi-2A ukuya kwi-63A (yiyo loo nto uluhlu luyi-1.5-16mm²).
Sinikezela ngetekhnoloji ezintathu zonxibelelwano, nganye ineenzuzo ezahlukeneyo:
Uqhagamshelo lweClamp yeScrew (ihashe lethu elisebenzayo): Isikrufu sentsimbi sicinezela umqhubi kwi-copper busbar, nto leyo eyenza i-weld ebandayo engangenisi gesi kwindawo yoqhagamshelwano. Olu luhlala lulona qhagamshelo luthembekileyo kwiisicelo zamandla aphezulu kuba isikrufu sisebenzisa i-torque eyi-2.0-3.5 Nm — eyaneleyo yokuguqula umqhubi wobhedu kancinci kwaye yenze i-metallurgical bond exhathisa ukukhululeka okubangelwa kukungcangcazela. Ingxaki? Ukufakela kuthatha imizuzwana eli-15-20 ngocingo ngalunye.
Uqhagamshelo lweNtwasahlobo oluThunyelwayo (olukhawulezayo kuthi): I-stainless steel spring clamp ibamba umqhubi ngaphandle kwezixhobo. Ukufakelwa kuthatha ngaphantsi kwemizuzwana emi-3. Nangona kunjalo — kwaye oku kubalulekile — uqhagamshelo lwe-push-in lukhawulelwe kubungakanani obukhulu be-conductor ye-16mm² kubuchwepheshe bangoku, oko kuthetha ukuba abanakukwazi ukusingatha i-conductor epheleleyo ye-70mm² ephambili kwibhloko ye-200A. Kwisondlo esiphambili, usadinga i-screw clamp okanye i-stud connection.
Uqhagamshelo lweStud/Bolt (olona lunzima kuthi): I-stud enemisonto ene-hex nut yamkela ii-terminals zeringi ezikrwelwe kwintambo. Olu lolona hlobo loqhagamshelo kuphela oluphatha ngokuthembekileyo ii-conductors ezingaphezulu kwe-35mm², kwaye yile nto siyichazayo kuzo zonke ii-terminals eziphambili ze-150A kunye ne-200A njengesiqhelo.
Iziqinisekiso kunye nokuThotyelwa kweMigangatho: Oko uMhloli wakho aza kukujonga
Ukuba kukho isifundo esinye endasifunda ngendlela enzima kwiminyaka yokuqala yomsebenzi wethu wokuvelisa, sesi: Iziqinisekiso azizizo izinto zokuhombisa ezikhethwayo — zingumqobo omncinci wokungena kuyo nayiphi na into ethengiswa kakhulu kwimizi-mveliso. Nantsi into ekufuneka uyiqinisekise kuyo nayiphi na i-DIN rail busbar terminal block specification sheet:

Umthetho wokungaqhubi ngokuqhubekayo we-NEC 80%: ukuba umthwalo wakho utsala i-160A rhoqo, udinga ibhloko yesiphelo enomlinganiselo we-200A ubuncinane. Ngenxa yokuba iibhloko zesiphelo azinawo ukupholisa okusebenzayo, indlela ekuphela kwayo yokususa ubushushu be-I²R kukudlula kumphezulu kunye nokujikeleza kwe-convection - kwaye ukungaphantsi kwebhloko kuthetha ukuwohloka kobushushu okusisigxina kwendlu ye-polyamide.
Inyathelo lesi-2: Qinisekisa iKlasi yeVoltage
Kwiinkqubo ze-480V ezinezigaba ezintathu (ezixhaphakileyo eMntla Melika), ibhloko enereyithingi ye-600V yanele. Kwiinkqubo ze-690V (ezixhaphakileyo kwiimveliso zaseYurophu) okanye kwiifakelo zelanga ze-1000V, udinga umlinganiselo opheleleyo we-1000V. Soloko uqinisekisa i-voltage ye-impulse standing (Uimp) ukongeza kwi-voltage ye-insulation elinganisiweyo (Ui) — i-impulse standing yiyo ekhusela kwi-transients ezibangelwa ngumbane kunye ne-switching surges.
Inyathelo lesi-3: Bala iiSekethe zakho zeSebe
Bala yonke isekethe ephumayo ekufuneka ifikelele kwi-busbar potential ephambili. Yongeza i-20% yamandla aseleyo ukuze kwandiswe kwixesha elizayo — kuba ukongeza izikhundla kamva kufuna ukuqhawulwa kwebhloko yonke kunye nokufakelwa iingcingo ezintsha, nto leyo ebiza kakhulu kunokufaka ibhloko enkulu kancinci ngaphambili.
Inyathelo lesi-4: Ubungakanani beengcingo ezihambelanayo

Kwizicelo eziphambili zokusasazwa kwamandla, i-SCCR ubuncinane engama-25kA kwi-voltage elinganisiweyo yeyona nto iphantsi kakhulu — nantoni na engaphantsi, kwaye i-terminal block yakho iba yi-fuse kwinkqubo yakho, kungekhona ngendlela elawulwayo.
Iindlela ezilungileyo zokufaka: Oko iDatasheet ingakuxeleli kona
Iidatha zikuxelela ixabiso le-torque kunye nobude be-wire strip. Abakuxeleli ukuba yintoni eyona nto ingalunganga kweli candelo. Nantsi into esiyifundileyo kumawakawaka eentsebenziswano zenkxaso yabathengi:
I-Torque ibaluleke ngaphezu kokuba ucinga — kwaye i-torque engaguqukiyo ixhaphake kalishumi kune-torque engaphezulu. I-screw terminal eqiniswe kwi-50% ye-torque elinganisiweyo iya kubonisa ukumelana nokuxinana okuphindwe kathathu ukuya kahlanu kunendlela ebekiweyo ngayo — kwaye kwi-200A, loo kumelana okongezelelweyo kuvelisa ubushushu obaneleyo ukuthambisa indlu ye-PA66 kwiiyure zokusebenza okuqhubekayo. Sithumela i-screwdriver ye-torque elinganisiweyo kunye nayo yonke isampuli yokuthunyelwa yokuqala kuba siyazi ukuba uninzi lweevenkile zepaneli zisebenzisa ii-screwdrivers zesandla ezingalinganiyo.
Ukusetyenziswa kwe-ferrule akunyanzelekanga ukuba kudlule i-16mm². Ii-copper copper conductors ezingenazo ii-ferrules ziyatyibilika phantsi koxinzelelo — ezinye ii-strings ziyachukumisa, ezinye azikwenzi oko. Indawo efanelekileyo yokuthintana incitshiswa ngama-20-30% xa kuthelekiswa ne-ferrule ekrwelwe kakuhle, kwaye oku kuthetha ukumelana okuphezulu, ubushushu obuphezulu, kwaye — kwimeko embi kakhulu — ukwaphuka kwee-string ngenxa yokujikeleza kobushushu. Sifaka iiferrule zobhedu ezihambelana ne-DIN 46228 kwiyunithi nganye yokupakisha iibhloko zesiphelo esingaphezulu kwe-25mm².
Iibhloko zesiphelo sebhasi zifuna umoya. Ngokungafaniyo neebhloko zesiphelo ezithwala umbane ngendlela enye yomqhubi, iibhloko zebhasi zigxininisa i-200A ngomzila omnye wobhedu ohamba ubude bebhloko yonke. Kwiphaneli exineneyo, ezi bhloko kufuneka zifakelwe ubuncinane isithuba somoya esiyi-10mm kumacala onke — kuba ubushushu obuveliswa yi-200A kwi-busbar ye-16mm² bumalunga ne-0.75W kwindawo yesiphelo ngasinye, kwaye ibhloko yeendawo ezingama-20 ivelisa i-15W rhoqo.
Imibuzo ebuzwa qho

Yintoni kanye kanye i-DIN Rail Busbar Terminal Block?
Ibhloko yesiphelo sebhasi ye-DIN rail sisixhobo sokudibanisa umbane esilungiselelwe ukusasazwa kombane — hayi iingcingo zesignali, hayi iisekethe zolawulo, kodwa ukuphathwa kwamandla okwenyaniIfakwa kwi-DIN rail eqhelekileyo ye-TS-35 (35mm ububanzi) kwaye isebenzisa i-copper busbar edibeneyo ukusasaza umbane oyintloko ongenayo kwiisekethe ezininzi zamasebe eziphumayo. Uphawu oluchazayo olwahlula ibhloko yesiphelo sebhasi kwibhloko eqhelekileyo yokutyibiliza yireyile yokuhambisa ekwabelwana ngayo: i-conductor enye enkulu engenayo inika amandla i-copper busbar, kwaye yonke indawo yesiphelo kuloo busbar ifikelela kwi-potential efanayo.
Kwifektri yethu, senza ezi bhloko ngokwee-configurations ukusuka kwiindlela ezimbini ukuya kwiindlela ezingama-20 — oko kuthetha ukuba i-feed enye ephambili engenayo inganika amandla ukuya kuthi ga kwiisekethe ezingama-20 zamasebe ezahlukeneyo ukusuka kwi-single compact DIN rail footprint. Oku kubaluleke kakhulu ekwakheni iipaneli zehlabathi lokwenyani kuba Iyasusa imfuneko yeebhloko zokusasazwa kwamandla ezahlukeneyo, inciphisa ixesha lokufakelwa kweentambo zephaneli malunga ne-40-60% xa kuthelekiswa nezisombululo ze-jumper ezisuka kwisiphelo sendlela ukuya kwisiphelo sendlela..
Ukuqonda i-1000V kunye ne-200A Ratings: Oko Kuthethwa Ngamanani Ngokwenene
Xa sithetha "nge-1000V rating" kunye "nomthamo we-200A," sibhekisa kwiiparamitha ezimbini ezahlukeneyo zoxinzelelo lombane - kwaye ukuzibhidanisa yimpazamo endiyibonileyo iinjineli ziyenza amaxesha amaninzi kwiminyaka yam eli-15 kweli shishini.
Uvavanyo lweVoltage (1000V): Umngeni woKhuseleko
Ireyithingi ye-1000V ixhomekeke kakhulu ekugqibeleleni kobushushu, kungekhona kumthamo womqhubi. Ngokwe I-IEC 60947-7-1, iibhloko zesiphelo ezenzelwe iisekethe ezifikelela kwi-1000V AC kufuneka zigcine umgama omncinci wokuqhekeka we-8mm kunye nomgama wokuphuma we-5.5mm phakathi kweepali ezikufutshane - kwaye le migama ilinganiswa kwindawo embi kakhulu yokunyamezelana. Ngenxa yokuba izinto ezihlala apho (ngesiqhelo yi-nylon ye-PA66 ene-30% yefayibha yeglasi eqinisiweyo) kufuneka zimelane ne-voltage ye-impulse elinganisiweyo ngaphandle kokulandelela okanye ukuqhekeka, sisebenzisa i-UL94 V-0 polyamide ethintela ilangatye ene-comparative tracking index (CTI) edlula i-400V.
Kumgca wethu wemveliso, ibhloko nganye elinganiswe nge-1000V ivavanywa amandla e-dielectric e-2200V AC imizuzwana engama-60 — oko kungaphezulu kwephindwe kabini kune-voltage elinganisiweyo, kuba Ubushushu kufuneka buhlale buphila kwii-overvoltages zexesha elifutshane eziveliswa ziindawo zoshishino zokwenyani imihla ngemihla ukusuka ekuqaliseni iimoto, ekutshintsheni i-contactor, kunye nokusebenza kwebhanki ye-capacitor..
Uvavanyo lwangoku (200A): Ingxaki yoLawulo loBushushu
Ireyithingi ye-200A ayiqondwa kakuhle ngokufanayo. Luphawu lobushushu, alungomda womzimba wokuhamba kwee-electron. Kwi-200A continuous current, ilahleko ze-I²R kwi-16mm² copper busbar zivelisa malunga ne-12-15 watts zobushushu ngemitha nganye - kwaye ngaphakathi kwiphaneli yokulawula evaliweyo kwi-40°C ambient, olo bushushu kufuneka luye ndaweni ithile. Yiyo loo nto ke kufuneka ukuba bube sendaweni ethile. Uvavanyo lwangoku lwebhloko yesiphelo luhlala lulinganiswa kubushushu obuthile (ngesiqhelo yi-40°C ngokwe-IEC 60947-7-1) kwaye luthatha i-convection yomoya ekhululekileyo ejikeleze ibhloko.
Isayensi yezinto zeBusbar: Kutheni iCopper ibaluleke ngaphezu kokuba ucinga
Ndifuna ukuthetha ngokucacileyo apha: Izinto zebhasi ezikwibhloko yesiphelo sendlela yeyona nto ibalulekileyo echaza ukusebenza kwayo kwihlabathi lokwenyani — kwaye yindawo apho abavelisi abanciphisa iindleko banciphisa khona iindleko.
Kukho izinto ezintathu zebhasi ezifumaneka rhoqo kwimarike, kwaye zisebenza ngendlela eyahlukileyo kakhulu:
| Izinto zeBhasibha | Ukuqhuba (% IACS) | Ukuqhuba kwe-Thermal (W/m·K) | Amandla okuThamba (MPa) | Isalathiso seendleko |
|---|---|---|---|---|
| I-Electrolytic Copper (C11000) | 99.9% | 391 | 220-250 | 100 |
| Ibrass (C26000) | 28% | 120 | 300-400 | 55 |
| Ubhedu oluGcwe ngeTin | 99.5% (umphezulu) | 385 | 220-250 | 115 |
Sisebenzisa i-C11000 electrolytic copper kuphela kuzo zonke iibhloko zethu ze-busbar terminal blocks zethu ezine-200A. Kutheni? Kuba Iibhasi zebrass ezisebenza kwi-200A ziya kufikelela kubushushu bomphezulu obuphezulu obumalunga nama-25-30°C kuneebhasi zebrass ezifanayo - kwaye loo mahluko wobushushu uguqulela ngokuthe ngqo kuxinzelelo oluphantsi loqhagamshelwano kwizikhululo zezikrufu, amazinga aphezulu e-oxidation, kunye nobomi obufutshane bemveliso. Umahluko wexabiso phakathi kobhedu nobhedu kwibhloko yebhasi yeendawo ezili-10 eqhelekileyo imalunga ne-$0.80-1.20 kwizinto ezikrwada — andifuni ukuvumelana apho.
Uluhlu lweeNtambo kunye neTekhnoloji yoQhagamshelo: Ukudibanisa iiConductors kunye nomthamo
Uluhlu lokwamkelwa kweentambo zebhloko yesiphelo sebhasi ye-200A ludla ngokuqala kwi-6mm² (AWG 10) ukuya kwi-70mm² (AWG 2/0) kwicala eliphambili lokufaka, kunye neeterminal zesebe ezamkela i-1.5mm² ukuya kwi-16mm² (AWG 16 ukuya kwi-6). Olu luhlu olubanzi lokwamkelwa alukho ngengozi — lubonisa inyani yombane yokusasazwa kwamandla: i-feed ephambili ithwala i-200A epheleleyo (yiyo loo nto iphezulu kwi-70mm²), ngelixa iisekethe zamasebe ngazinye zinokutsala naphi na ukusuka kwi-2A ukuya kwi-63A (yiyo loo nto uluhlu luyi-1.5-16mm²).
Sinikezela ngetekhnoloji ezintathu zonxibelelwano, nganye ineenzuzo ezahlukeneyo:
Uqhagamshelo lweClamp yeScrew (ihashe lethu elisebenzayo): Isikrufu sentsimbi sicinezela umqhubi kwi-copper busbar, nto leyo eyenza i-weld ebandayo engangenisi gesi kwindawo yoqhagamshelwano. Olu luhlala lulona qhagamshelo luthembekileyo kwiisicelo zamandla aphezulu kuba isikrufu sisebenzisa i-torque eyi-2.0-3.5 Nm — eyaneleyo yokuguqula umqhubi wobhedu kancinci kwaye yenze i-metallurgical bond exhathisa ukukhululeka okubangelwa kukungcangcazela. Ingxaki? Ukufakela kuthatha imizuzwana eli-15-20 ngocingo ngalunye.
Uqhagamshelo lweNtwasahlobo oluThunyelwayo (olukhawulezayo kuthi): I-stainless steel spring clamp ibamba umqhubi ngaphandle kwezixhobo. Ukufakelwa kuthatha ngaphantsi kwemizuzwana emi-3. Nangona kunjalo — kwaye oku kubalulekile — uqhagamshelo lwe-push-in lukhawulelwe kubungakanani obukhulu be-conductor ye-16mm² kubuchwepheshe bangoku, oko kuthetha ukuba abanakukwazi ukusingatha i-conductor epheleleyo ye-70mm² ephambili kwibhloko ye-200A. Kwisondlo esiphambili, usadinga i-screw clamp okanye i-stud connection.
Uqhagamshelo lweStud/Bolt (olona lunzima kuthi): I-stud enemisonto ene-hex nut yamkela ii-terminals zeringi ezikrwelwe kwintambo. Olu lolona hlobo loqhagamshelo kuphela oluphatha ngokuthembekileyo ii-conductors ezingaphezulu kwe-35mm², kwaye yile nto siyichazayo kuzo zonke ii-terminals eziphambili ze-150A kunye ne-200A njengesiqhelo.
Iziqinisekiso kunye nokuThotyelwa kweMigangatho: Oko uMhloli wakho aza kukujonga
Ukuba kukho isifundo esinye endasifunda ngendlela enzima kwiminyaka yokuqala yomsebenzi wethu wokuvelisa, sesi: Iziqinisekiso azizizo izinto zokuhombisa ezikhethwayo — zingumqobo omncinci wokungena kuyo nayiphi na into ethengiswa kakhulu kwimizi-mveliso. Nantsi into ekufuneka uyiqinisekise kuyo nayiphi na i-DIN rail busbar terminal block specification sheet:

Indlela yokukhetha i-DIN Rail Busbar Terminal Block efanelekileyo: Inkqubo enamanyathelo ama-5
Emva kweminyaka eli-15 ndiphendula imibuzo yobugcisa, ndiyihlalutyile inkqubo yokukhetha yaba zizigqibo ezintlanu ezilandelelanayo. Tsiba naliphi na inyathelo, kwaye uya kuchitha imali eninzi kwizixhobo ezichazwe ngokugqithisileyo okanye - okubi ngakumbi - ufake ibhloko yesiphelo eba yingozi yomlilo.
Inyathelo 1: Chonga i-Outcoming Current yakho ephezulu kakhulu
Musa ukusebenzisa ireyithingi ye-circuit breaker njengesiseko sakho sangoku. Linganisa okanye ubale umsinga womthwalo oqhubekayo phantsi kweemeko ezimbi kakhulu. Umthetho wokungaqhubi ngokuqhubekayo we-NEC 80%: ukuba umthwalo wakho utsala i-160A rhoqo, udinga ibhloko yesiphelo enomlinganiselo we-200A ubuncinane. Ngenxa yokuba iibhloko zesiphelo azinawo ukupholisa okusebenzayo, indlela ekuphela kwayo yokususa ubushushu be-I²R kukudlula kumphezulu kunye nokujikeleza kwe-convection - kwaye ukungaphantsi kwebhloko kuthetha ukuwohloka kobushushu okusisigxina kwendlu ye-polyamide.
Inyathelo lesi-2: Qinisekisa iKlasi yeVoltage
Kwiinkqubo ze-480V ezinezigaba ezintathu (ezixhaphakileyo eMntla Melika), ibhloko enereyithingi ye-600V yanele. Kwiinkqubo ze-690V (ezixhaphakileyo kwiimveliso zaseYurophu) okanye kwiifakelo zelanga ze-1000V, udinga umlinganiselo opheleleyo we-1000V. Soloko uqinisekisa i-voltage ye-impulse standing (Uimp) ukongeza kwi-voltage ye-insulation elinganisiweyo (Ui) — i-impulse standing yiyo ekhusela kwi-transients ezibangelwa ngumbane kunye ne-switching surges.
Inyathelo lesi-3: Bala iiSekethe zakho zeSebe
Bala yonke isekethe ephumayo ekufuneka ifikelele kwi-busbar potential ephambili. Yongeza i-20% yamandla aseleyo ukuze kwandiswe kwixesha elizayo — kuba ukongeza izikhundla kamva kufuna ukuqhawulwa kwebhloko yonke kunye nokufakelwa iingcingo ezintsha, nto leyo ebiza kakhulu kunokufaka ibhloko enkulu kancinci ngaphambili.
Inyathelo lesi-4: Ubungakanani beengcingo ezihambelanayo
Qinisekisa ukuba uluhlu lokwamkelwa kwentambo yebhloko yesiphelo lugubungela zombini umqhubi wakho oyintloko wesondlo KUNYE nomqhubi wakho omncinci wesebe. Eyona mpazamo ixhaphakileyo yokukhetha endiyibonayo kukuchaza ibhloko ye-200A elindele ukuwela ucingo lwesebe lwe-1.5mm² — uninzi lweebhloko ezinombane ophezulu azikwazi ukubamba ngokuthembekileyo ii-conductors ezingaphantsi kwe-4mm². Kule meko, sebenzisa iphini yokunciphisa okanye i-ferrule, kodwa qwalasela ixesha elongezelelweyo lokuhlanganisa.
Inyathelo lesi-5: Qinisekisa uQhagamshelwano lwe-SCCR
Cela isatifikethi sovavanyo lwe-SCCR kumenzi wakho. Ixabiso le-SCCR kufuneka libe phezulu kune-fault current ekhoyo kwindawo yokufakela. Kwizicelo eziphambili zokusasazwa kwamandla, i-SCCR ubuncinane engama-25kA kwi-voltage elinganisiweyo yeyona nto iphantsi kakhulu — nantoni na engaphantsi, kwaye i-terminal block yakho iba yi-fuse kwinkqubo yakho, kungekhona ngendlela elawulwayo.
Iindlela ezilungileyo zokufaka: Oko iDatasheet ingakuxeleli kona
Iidatha zikuxelela ixabiso le-torque kunye nobude be-wire strip. Abakuxeleli ukuba yintoni eyona nto ingalunganga kweli candelo. Nantsi into esiyifundileyo kumawakawaka eentsebenziswano zenkxaso yabathengi:
I-Torque ibaluleke ngaphezu kokuba ucinga — kwaye i-torque engaguqukiyo ixhaphake kalishumi kune-torque engaphezulu. I-screw terminal eqiniswe kwi-50% ye-torque elinganisiweyo iya kubonisa ukumelana nokuxinana okuphindwe kathathu ukuya kahlanu kunendlela ebekiweyo ngayo — kwaye kwi-200A, loo kumelana okongezelelweyo kuvelisa ubushushu obaneleyo ukuthambisa indlu ye-PA66 kwiiyure zokusebenza okuqhubekayo. Sithumela i-screwdriver ye-torque elinganisiweyo kunye nayo yonke isampuli yokuthunyelwa yokuqala kuba siyazi ukuba uninzi lweevenkile zepaneli zisebenzisa ii-screwdrivers zesandla ezingalinganiyo.
Ukusetyenziswa kwe-ferrule akunyanzelekanga ukuba kudlule i-16mm². Ii-copper copper conductors ezingenazo ii-ferrules ziyatyibilika phantsi koxinzelelo — ezinye ii-strings ziyachukumisa, ezinye azikwenzi oko. Indawo efanelekileyo yokuthintana incitshiswa ngama-20-30% xa kuthelekiswa ne-ferrule ekrwelwe kakuhle, kwaye oku kuthetha ukumelana okuphezulu, ubushushu obuphezulu, kwaye — kwimeko embi kakhulu — ukwaphuka kwee-string ngenxa yokujikeleza kobushushu. Sifaka iiferrule zobhedu ezihambelana ne-DIN 46228 kwiyunithi nganye yokupakisha iibhloko zesiphelo esingaphezulu kwe-25mm².
Iibhloko zesiphelo sebhasi zifuna umoya. Ngokungafaniyo neebhloko zesiphelo ezithwala umbane ngendlela enye yomqhubi, iibhloko zebhasi zigxininisa i-200A ngomzila omnye wobhedu ohamba ubude bebhloko yonke. Kwiphaneli exineneyo, ezi bhloko kufuneka zifakelwe ubuncinane isithuba somoya esiyi-10mm kumacala onke — kuba ubushushu obuveliswa yi-200A kwi-busbar ye-16mm² bumalunga ne-0.75W kwindawo yesiphelo ngasinye, kwaye ibhloko yeendawo ezingama-20 ivelisa i-15W rhoqo.
Imibuzo ebuzwa qho
Q: Ndingasebenzisa ibhloko enye yesiphelo sebhasi ye-200A kuzo zombini ii-AC kunye ne-DC?
Ewe, kodwa kukho izilumkiso ezibalulekileyo. Uvavanyo lwangoku kufuneka luncitshiswe kwi-DC kuba ii-DC arcs azizicimi ngokwazo kwiindawo zokunqumla u-zero. Ngokwe-IEC 60947-7-1, iibhloko zesiphelo ezisetyenziswa kwiisekethe ze-DC kufuneka zincitshiswe ziye kwi-80% yovavanyo lwazo lwangoku lwe-AC — ngoko ke ibhloko ye-200A AC iba yibhloko ye-160A DC. Ukongeza, i-DC polarity kufuneka ihambelane kuzo zonke ii-terminals ezabelana nge-busbar; ukuxuba ii-polarity kwi-busbar efanayo kudala i-dead short.
Q: Yintoni umahluko phakathi kwebhloko yesiphelo sebhasi kunye nebhloko yokusasazwa kwamandla?
Ibhloko yesiphelo sebhasi idibanisa i-busbar ngaphakathi kwendlu yesiphelo kwaye ifakelwe kwi-DIN rail. Ibhloko yokusasazwa kwamandla (PDB) idla ngokuba sisixhobo esikhulu, esizimeleyo esine-enclosure eyahlukileyo enokuthi ifakwe okanye ingafakelwa kwi-DIN rail. Iibhloko zesiphelo seBusbar zibonelela ngoxinano oluphezulu kunye nocingo olulula kwiisicelo ukuya kuthi ga kwi-200A; ii-PDB zigqwesa ngaphezu kwe-200A apho i-wire bending radii kunye nokuchithwa kobushushu kwenza indlela edibeneyo ingasebenzi.
Q: Zihlala ixesha elingakanani iibhloko ze-DIN rail busbar terminal?
Phantsi kweemeko ezilinganisiweyo (kwi-40°C ambient, ≤80% umthwalo oqhubekayo), ibhloko yesiphelo sebhasi yobhedu efakwe ngokufanelekileyo enezindlu ze-PA66 inobomi boyilo beminyaka engama-20 nangaphezulu. Eyona nto ithintela ubomi phantse isoloko ixhomekeke kubushushu obuqhelekileyo — ukwandiswa nokucutheka kwe-copper busbar (CTE: 17×10⁻⁶/K) ngokuchasene ne-PA66 housing (CTE: 80×10⁻⁶/K) ngokuthe ngcembe kukhulula uqhagamshelo lwezikrufu kwiibhayisekile ezingamawaka. Ukulungiswa kwakhona kwe-torque minyaka le ngexesha lokugcinwa okucwangcisiweyo kwandisa ubomi benkonzo ngokubalulekileyo.
Q: Ndingazifumana ii-busbar configurations ezenziwe ngokwezifiso?
Ewe. Njengomvelisi onokwenza isikhunta ngaphakathi endlwini, sihlala sivelisa iibhloko zesiphelo sebhasi ezenziwe ngokwezifiso ezineenombolo zeepali ezingezizo ezisemgangathweni, izilinganiso zamandla axutyiweyo kwibhasi enye, iindawo ezikhethekileyo zombala zokubhala ikhowudi yevolthi, kunye nokumakisha/ukubhala iilebheli ngokwezifiso. Ubungakanani obuncinci be-odolo yoqwalaselo olwenziwe ngokwezifiso luqala kwi-1,000 yeeyunithi, kunye nexabiso leyunithi libandakanyiwe kwixabiso leyunithi. Nxibelelana neqela lethu lobunjineli ku- sara@nbjguang.com ngokweemfuno zakho.
Q: Ngaba iibhloko zesiphelo se-J-Guang ziyahambelana nezixhobo ezivela kwezinye iimpawu?
Iibhloko zethu zesitishi sikaloliwe se-DIN zisebenzisa iprofayili kaloliwe ye-TS-35 esemgangathweni kushishino kunye nesithuba esiqhelekileyo semigca ephakathi (ngesiqhelo yi-6mm, 8mm, okanye i-10mm kuxhomekeke kuluhlu). Iibrakethi zokugqibela, iipleyiti zokwahlulahlula, kunye nemicu yokumakisha ngokubanzi iyahambelana neebhrendi ezinkulu (Weidmüller W-Series, Phoenix Contact UK-Series) kuba ezi milinganiselo ziyimigangatho yoshishino - nangona sihlala sicebisa ukuqinisekisa ukuhambelana koomatshini nesampulu ngaphambi kokuba sizibophelele kwiiodolo ezinkulu.
Kutheni i-J-Guang ifuna iimfuno zakho ze-DIN Rail Busbar Terminal Block?
