Iyini Ngempela I-DIN Rail Busbar Terminal Block?
Ibhulokhi yesiteshi sebhasi yesitimela i-DIN iyisixhumi sikagesi esihlanganisiwe esenzelwe ukusatshalaliswa kwamandla — hhayi izintambo zesiginali, hhayi izifunda zokulawula, kodwa ukuphathwa kwamandla kwangempelaIfakwa ku-rail ejwayelekile ye-TS-35 (35mm ububanzi) ye-DIN futhi isebenzisa i-busbar yethusi ehlanganisiwe ukusabalalisa amandla angenayo ayinhloko kumasekethe amaningi egatsha aphumayo. Isici esichazayo esihlukanisa ibhulokhi yesiphelo sebhasi kusukela kubhulokhi evamile yokuphakelayo yisitimela sokuhambisa esihlanganyelwe: i-conductor eyodwa enkulu engenayo inika amandla ibhasi lethusi, futhi yonke indawo yesiphelo kuleyo bhasi ithinta amandla afanayo.
Embonini yethu, sakha la mabhulokhi ngezindlela ezi-2 kuya kwezi-20 — okusho ukuthi i-feed eyodwa enkulu engenayo inganika amandla amasekethe amagatsha afinyelela kwangu-20 avela ku-DIN rail footprint eyodwa encane. Lokhu kubaluleke kakhulu ekwakhiweni kwamaphaneli omhlaba wangempela ngoba iqeda isidingo samabhulokhi okusabalalisa amandla ahlukene, inciphisa isikhathi sokuxhuma amaphaneli cishe ngo-40-60% uma kuqhathaniswa nezixazululo ze-jumper ezisuka ku-terminal ziye ku-terminal ngazinye..
Ukuqonda Izilinganiso ze-1000V kanye ne-200A: Okushiwo Yizinombolo Ngempela
Uma sikhuluma "ngesilinganiso se-1000V" kanye "nomthamo we-200A," sibhekisela kumapharamitha amabili ahlukene ngokuphelele okucindezeleka kukagesi - futhi ukuwadida kuyiphutha engibonile onjiniyela bewenza izikhathi eziningi kakhulu eminyakeni yami engu-15 kule mboni.
Isilinganiso Se-Voltage (1000V): Inselele Yokuvimbela Ukushisa
Isilinganiso se-1000V simayelana nobuqotho bokufudumeza, hhayi umthamo womqhubi. Ngokwe I-IEC 60947-7-1, amabhlogo okugcina enzelwe amasekethe afinyelela ku-1000V AC kumele agcine amabanga amancane okucwila angu-8mm kanye namabanga okuphuma angu-5.5mm phakathi kwezigxobo eziseduze — futhi lawa mabanga alinganiswa esigxotsheni sokubekezelelana okubi kakhulu. Ngenxa yokuthi izinto zokwakha (ngokuvamile i-nylon ye-PA66 enokuqinisa i-fiber yengilazi engu-30%) kumele zikwazi ukumelana ne-voltage ye-impulse elinganisiwe ngaphandle kokulandelela noma ukuphuka, sisebenzisa i-polyamide ye-UL94 V-0 evimbela ilangabi ene-comparative tracking index (CTI) edlula i-400V.
Emgqeni wethu wokukhiqiza, ibhulokhi ngayinye enesilinganiso esingu-1000V idlula ekuhlolweni kwamandla e-dielectric angu-2200V AC imizuzwana engu-60 — lokho kungaphezu kokuphindwe kabili kwe-voltage enesilinganiso, ngoba Ukushisa kumele kuqhubeke isikhathi eside ngenxa yokushisa kwesikhashana okwenziwa yizindawo zangempela zezimboni nsuku zonke kusukela ekuqaleni kwezimoto, ukushintshana kwe-contactor, kanye nokusebenza kwebhange le-capacitor.
Isilinganiso Samanje (200A): Inkinga Yokuphathwa Kokushisa
Isilinganiso sama-200A siqondwa kabi ngokufanayo. Kuyisilinganiso sokushisa, hhayi umkhawulo ongokoqobo ekugelezeni kwama-electron. Ku-200A continuous current, ukulahlekelwa kwe-I²R kubha yebhasi yethusi engu-16mm² kukhiqiza cishe ama-watts angu-12-15 okushisa ngemitha ngayinye — futhi ngaphakathi kwephaneli yokulawula evaliwe endaweni engama-40°C, lokho kushisa kumele kuye ndawana thile. Yingakho Isilinganiso samanje sebhulokhi yokugcina sihlala silinganiswa ekushiseni okuqondile (ngokuvamile okungu-40°C ngokwe-IEC 60947-7-1) futhi sithatha ukujikeleza komoya okukhululekile okuzungeze ibhulokhi.
Isayensi Yezinto Ezisetshenziswayo ZaseBusbar: Kungani Ithusi Libaluleke Kakhulu Kunokuba Ucabanga
Ngifuna ukukhuluma ngokusobala lapha: Izinto ze-busbar ngaphakathi kwebhulokhi yesiphelo ziyisici esibaluleke kakhulu esinquma ukusebenza kwayo kwangempela — futhi yindawo lapho abakhiqizi abanciphisa izindleko besika khona amathuba.
Kunezinhlobo ezintathu zezinto ze-busbar ezivame ukutholakala emakethe, futhi zisebenza ngendlela ehluke kakhulu:
| Izinto ze-Busbar | Ukuqhuba (% IACS) | Ukushisa Okuphezulu (W/m·K) | Amandla Okudonsa (i-MPa) | Inkomba Yezindleko |
|---|---|---|---|---|
| Ithusi Le-Electrolytic (C11000) | 99.9% | 391 | 220-250 | 100 |
| Ithusi (C26000) | 28% | 120 | 300-400 | 55 |
| Ithusi Elifakwe I-Tin | 99.5% (ubuso) | 385 | 220-250 | 115 |
Sisebenzisa ithusi le-C11000 electrolytic kuphela kuzo zonke izithiyo zethu ze-busbar terminal blocks ezinesilinganiso esingu-200A. Kungani? Ngoba Amabha ebhasi ethusi asebenza ku-200A azofinyelela izinga lokushisa eliphezulu elingaphezu kuka-25-30°C kune-bha ebhasi ethusi elilinganayo — futhi lowo mehluko wokushisa uhumusha ngokuqondile ekucindezelweni okuncishisiwe kokuxhumana kuma-terminals esikulufo, amazinga aphezulu okushiswa kwe-oxidation, kanye nesikhathi sokuphila somkhiqizo esifinyeziwe. Umehluko wezindleko phakathi kwethusi nethusi lebhulokhi yebhasi yezindawo eziyi-10 ejwayelekile cishe u-$0.80-1.20 ngezinto ezingavuthiwe — akukhona lapho ngizimisele khona ukuyekethisa.
Ububanzi Bezintambo Nobuchwepheshe Bokuxhuma: Ukuqondanisa Ama-Conductor Nomthamo
Ububanzi bokwamukelwa kwentambo kwebhulokhi yesiteshi sebhasi engu-200A buvame ukusuka ku-6mm² (AWG 10) kuya ku-70mm² (AWG 2/0) ohlangothini oluyinhloko lokufaka, kanti ama-terminal egatsha amukela u-1.5mm² kuya ku-16mm² (AWG 16 kuya ku-6). Lolu hlu olubanzi lokwamukelwa alulona olunengozi — lubonisa iqiniso likagesi lokusatshalaliswa kwamandla: i-feed eyinhloko ithwala i-200A ephelele (ngakho-ke ingu-70mm² ephezulu), kuyilapho amasekethe egatsha ngalinye angadonsa noma yikuphi kusuka ku-2A kuya ku-63A (ngakho-ke ingu-1.5-16mm² ububanzi).
Sinikeza ubuchwepheshe obuthathu bokuxhumana, ngabunye bunezinzuzo ezihlukile:
Ukuxhumeka Kwesikulufo Sesikrufu (ihhashi lethu elisebenzayo): Isikulufu sensimbi sicindezela umqhubi ngokumelene nebhasi yethusi, okwenza kube nokushintshwa okubandayo okungenagesi endaweni yokuxhumana. Lokhu kusalokhu kuyindlela ethembekile kakhulu yokuxhumana kwezicelo zamandla aphezulu ngoba isikulufu sisebenzisa i-torque engu-2.0-3.5 Nm — eyanele ukuguquguqula umqhubi wethusi kancane futhi sakhe isibopho sensimbi esimelana nokuxega okubangelwa ukudlidliza. Ububi? Ukufakwa kuthatha imizuzwana eyi-15-20 ngocingo ngalunye.
Ukuxhumeka Kwentwasahlobo Okusheshayo (okushesha kakhulu): I-clamp yesipilingi yensimbi engagqwali ibamba umqhubi ngaphandle kwamathuluzi. Ukufakwa kuthatha ngaphansi kwemizuzwana emi-3. Kodwa-ke — futhi lokhu kubalulekile — ukuxhumeka kokucindezela kukhawulelwe kusayizi omkhulu womqhubi ongu-16mm² kubuchwepheshe bamanje, okusho ukuthi abakwazi ukusingatha umqhubi ophelele wokufaka ongu-70mm² kubhulokhi engu-200A. Ukuze uthole ukudla okuyinhloko, usadinga uxhumano lwe-screw clamp noma i-stud.
Uxhumano lwe-Stud/Bolt (olunzima kakhulu kithi): I-stud enentambo ene-hex nut yamukela ama-terminal endandatho aboshwe ocingweni. Lolu uhlobo lokuxhuma kuphela oluphatha ngokuthembekile ama-conductor angaphezu kuka-35mm², futhi yilokho esikuchazayo kuzo zonke ama-terminal okufaka ayinhloko angu-150A kanye no-200A njengokujwayelekile.
Izitifiketi Nokuhambisana Nezindinganiso: Lokho Umhloli Wakho Azokuhlola
Uma kukhona isifundo esisodwa engisifunde kanzima eminyakeni yokuqala yomsebenzi wethu wokukhiqiza, yilesi: izitifiketi azizona izihlobiso zokuzikhethela — ziyisithiyo esincane sokungena kunoma yikuphi ukuthengwa kwezimboni okungathi sína. Nakhu okudingeka ukuqinisekise kunoma yiliphi ishidi lencazelo yebhulokhi yebhulokhi yesitimela se-DIN rail busbar:
I-IEC 60947-7-1 — Lena indinganiso yamazwe ngamazwe eyisisekelo yamabhulokhi e-terminal asetshenziswa kuma-switchgear aphansi kanye nama-controlgear assemblies. Ichaza i-voltage elinganisiwe (≤1000V AC), amandla kagesi alinganisiwe, kanye — okubaluleke kakhulu — izinqubo zokuhlola isilinganiso samanje se-short-circuit (SCCR). Nge isichibiyelo sakamuva se-IEC 60947-7-1, amabhlogo wokugcina kumele manje amemezele inani lawo le-SCCR ngokucacile, okumele lihlanganiswe namadivayisi okuvikela angaphezulu.
I-UL 1059 — Okufanayo kwaseNyakatho Melika, okumboza amabhlogo okugcina afinyelela ku-1500V. Ukuhlolwa kwe-UL 1059 kuqinile kakhulu kune-IEC ezindaweni eziningana ezibalulekile: kudinga ukuhlolwa kokumelana ne-dielectric ku-voltage elinganisiwe engu-2× + 1000V (uma kuqhathaniswa ne-voltage elinganisiwe engu-2× ye-IEC), futhi kuphoqelela ukuhlolwa kokujikeleza kokushisa ku-current elinganisiwe yemijikelezo engu-50 (uma kuqhathaniswa nokuhlolwa kokuphakama kokushisa okungaguquki kwe-IEC). Ngokwe Uhlelo lwe-UL 1059 6-2024, ukubuyekezwa kwakamuva kwenezela izidingo ezithuthukisiwe zamabhulokhi okugcina okuvikelayo.
Iphothifoliyo yethu yesitifiketi njenge umenzi webhulokhi yesiteshi sebhasi i-din rail kufaka phakathi: Ukumakwa kwe-CE (ukuthobela imithetho ye-EU), ukufakwa ohlwini lwe-UL (ifayela liyatholakala uma liceliwe), ukuphathwa kwekhwalithi ye-ISO 9001:2008, ukuhlolwa kwe-SGS komuntu wesithathu, ukuthobela imithetho ye-RoHS, kanye nesimemezelo se-REACH. Konke ukuthunyelwa kufaka isitifiketi sokuhambisana nezinombolo zebhetshi ezingalandelelwa.
Kungani Kufanele Ukhethe Umkhiqizi We-Chinese DIN Rail Busbar Terminal Block?
Ngizophendula lo mbuzo ngqo ngoba amaqembu okuthenga asibuza lokhu njalo ngesonto. Imboni yezingxenye zikagesi ishintshe kakhulu eminyakeni eyishumi edlule. Amandla okukhiqiza aseShayina avale igebe lekhwalithi nabakhiqizi baseYurophu nabaseMelika — ngenkathi egcina inzuzo yezindleko ezingama-30-50% evela ekukhiqizeni okuhlanganisiwe okuqondile, hhayi ekushintsheni izinto noma ekuhlolweni.
Nakhu okushiwo ukuhlanganiswa okuqondile ekusebenzeni esikhungweni sethu: Sithela izikhunta zethu zokujova endlini. Sinyathela amabhara ethu ethusi kusuka ku-C11000 copper strip eqinisekisiwe etholakala ku-Jiangxi Copper (omunye wabakhiqizi bethusi abakhulu emhlabeni). Sisebenzisa imigqa yethu yokuhlanganisa ezenzakalelayo. Futhi sigcina ilebhu yethu yokuhlola yangaphakathi ehlonyiswe ngabahloli be-dielectric, ama-micro-ohmmeter, amakhamera okuthatha izithombe zokushisa, kanye negumbi lokuhlola impilo elisheshayo lamahora angu-500.
Lokhu kuhlanganiswa okuqondile kususa izendlalelo ezintathu ze-markup — umsabalalisi wezinto zokusetshenziswa, umhlinzeki wezingxenye ezincane, kanye ne-contract assembler — ezivame ukufakwa emananini amabhulokhi e-terminal anegama laseNtshonalanga (okufanele ngiqaphele ukuthi akhiqizwa kabanzi eShayina noma kunjalo, ngelebula ehlukile).
Kwabakhi be-OEM kanye nabakhi bephaneli abathola usizo kusuka efektri yethu ngqo, ezomnotho zihumusha kanje:

Izindlela Ezinhle Zokufaka: Lokho Ishidi Ledatha Elingakutsheli Khona
Amashidi edatha akutshela amanani e-torque kanye nobude be-wire strip. Abakutsheli ukuthi yini ngempela ehamba kabi ensimini. Nakhu esikufundile ezinkulungwaneni zokusebenzelana kokusekelwa kwamakhasimende:
I-Torque ibaluleke kakhulu kunalokho ocabanga ngakho — futhi i-torque engakafiki ezingeni elifanele ivame kakhulu ngokuphindwe kayishumi kunoku-torque engakafiki ezingeni elifanele. I-terminal yesikulufu eqiniswe ku-50% we-torque ekalwe izobonisa ukumelana kokuthintana okuphindwe kathathu kuya kahlanu kunencazelo - futhi ku-200A, lokho kumelana okwengeziwe kukhiqiza ukushisa okwanele ukuthambisa indlu ye-PA66 zingakapheli amahora okusebenza okuqhubekayo. Sithumela i-screwdriver ye-torque elinganisiwe nayo yonke isampula yokuthunyelwa e-oda lokuqala ngoba siyazi ukuthi izitolo eziningi zamaphaneli zisebenzisa ama-screwdriver aphathwayo angalinganisiwe.
Ukusetshenziswa kwe-ferrule akuyona into yokuzikhethela ngaphezu kwe-16mm². Ama-conductor ethusi aqinile angenazo izimbobo zomoya ayavuleka ngaphansi kokucindezelwa — eminye imicu iyathintana, eminye ayithinti. Indawo yokuthintana esebenzayo incishiswa ngo-20-30% uma kuqhathaniswa ne-ferrule egobekile kahle, futhi lokhu kusho ukumelana okuphezulu, izinga lokushisa eliphakeme, kanye — esimweni esibi kakhulu — nokuphuka kwemicu ngenxa yokujikeleza kokushisa. Sifaka ama-ferrule ethusi ahambisana ne-DIN 46228 kuzo zonke iyunithi zokupakisha zamabhulokhi esiphelo ezingaphezu kuka-25mm².
Amabhulokhi e-terminal e-Busbar adinga umoya opholile. Ngokungafani namabhulokhi okugcina adlulayo athwala ugesi ngendlela eyodwa yomqhubi, amabhulokhi ebhasi agxila ku-200A ngesitimela esisodwa sethusi esihamba ngobude bonke bebhulokhi. Ephanelini eligcwele kakhulu, la mabhulokhi kumele afakwe okungenani igebe lomoya elingu-10mm kuzo zonke izinhlangothi — ngoba ukushisa okukhiqizwa yi-200A kubha yebhasi engu-16mm² cishe kungama-0.75W ngesikhundla setheminali, kanti ibhulokhi enezindawo ezingu-20 ikhiqiza ama-15W njalo.

Yingakho Isilinganiso samanje sebhulokhi yokugcina sihlala silinganiswa ekushiseni okuqondile (ngokuvamile okungu-40°C ngokwe-IEC 60947-7-1) futhi sithatha ukujikeleza komoya okukhululekile okuzungeze ibhulokhi.
Isayensi Yezinto Ezisetshenziswayo ZaseBusbar: Kungani Ithusi Libaluleke Kakhulu Kunokuba Ucabanga
Ngifuna ukukhuluma ngokusobala lapha: Izinto ze-busbar ngaphakathi kwebhulokhi yesiphelo ziyisici esibaluleke kakhulu esinquma ukusebenza kwayo kwangempela — futhi yindawo lapho abakhiqizi abanciphisa izindleko besika khona amathuba.
Kunezinhlobo ezintathu zezinto ze-busbar ezivame ukutholakala emakethe, futhi zisebenza ngendlela ehluke kakhulu:
| Izinto ze-Busbar | Ukuqhuba (% IACS) | Ukushisa Okuphezulu (W/m·K) | Amandla Okudonsa (i-MPa) | Inkomba Yezindleko |
|---|---|---|---|---|
| Ithusi Le-Electrolytic (C11000) | 99.9% | 391 | 220-250 | 100 |
| Ithusi (C26000) | 28% | 120 | 300-400 | 55 |
| Ithusi Elifakwe I-Tin | 99.5% (ubuso) | 385 | 220-250 | 115 |
Sisebenzisa ithusi le-C11000 electrolytic kuphela kuzo zonke izithiyo zethu ze-busbar terminal blocks ezinesilinganiso esingu-200A. Kungani? Ngoba Amabha ebhasi ethusi asebenza ku-200A azofinyelela izinga lokushisa eliphezulu elingaphezu kuka-25-30°C kune-bha ebhasi ethusi elilinganayo — futhi lowo mehluko wokushisa uhumusha ngokuqondile ekucindezelweni okuncishisiwe kokuxhumana kuma-terminals esikulufo, amazinga aphezulu okushiswa kwe-oxidation, kanye nesikhathi sokuphila somkhiqizo esifinyeziwe. Umehluko wezindleko phakathi kwethusi nethusi lebhulokhi yebhasi yezindawo eziyi-10 ejwayelekile cishe u-$0.80-1.20 ngezinto ezingavuthiwe — akukhona lapho ngizimisele khona ukuyekethisa.
Ububanzi Bezintambo Nobuchwepheshe Bokuxhuma: Ukuqondanisa Ama-Conductor Nomthamo
Ububanzi bokwamukelwa kwentambo kwebhulokhi yesiteshi sebhasi engu-200A buvame ukusuka ku-6mm² (AWG 10) kuya ku-70mm² (AWG 2/0) ohlangothini oluyinhloko lokufaka, kanti ama-terminal egatsha amukela u-1.5mm² kuya ku-16mm² (AWG 16 kuya ku-6). Lolu hlu olubanzi lokwamukelwa alulona olunengozi — lubonisa iqiniso likagesi lokusatshalaliswa kwamandla: i-feed eyinhloko ithwala i-200A ephelele (ngakho-ke ingu-70mm² ephezulu), kuyilapho amasekethe egatsha ngalinye angadonsa noma yikuphi kusuka ku-2A kuya ku-63A (ngakho-ke ingu-1.5-16mm² ububanzi).
Sinikeza ubuchwepheshe obuthathu bokuxhumana, ngabunye bunezinzuzo ezihlukile:
Ukuxhumeka Kwesikulufo Sesikrufu (ihhashi lethu elisebenzayo): Isikulufu sensimbi sicindezela umqhubi ngokumelene nebhasi yethusi, okwenza kube nokushintshwa okubandayo okungenagesi endaweni yokuxhumana. Lokhu kusalokhu kuyindlela ethembekile kakhulu yokuxhumana kwezicelo zamandla aphezulu ngoba isikulufu sisebenzisa i-torque engu-2.0-3.5 Nm — eyanele ukuguquguqula umqhubi wethusi kancane futhi sakhe isibopho sensimbi esimelana nokuxega okubangelwa ukudlidliza. Ububi? Ukufakwa kuthatha imizuzwana eyi-15-20 ngocingo ngalunye.
Ukuxhumeka Kwentwasahlobo Okusheshayo (okushesha kakhulu): I-clamp yesipilingi yensimbi engagqwali ibamba umqhubi ngaphandle kwamathuluzi. Ukufakwa kuthatha ngaphansi kwemizuzwana emi-3. Kodwa-ke — futhi lokhu kubalulekile — ukuxhumeka kokucindezela kukhawulelwe kusayizi omkhulu womqhubi ongu-16mm² kubuchwepheshe bamanje, okusho ukuthi abakwazi ukusingatha umqhubi ophelele wokufaka ongu-70mm² kubhulokhi engu-200A. Ukuze uthole ukudla okuyinhloko, usadinga uxhumano lwe-screw clamp noma i-stud.
Uxhumano lwe-Stud/Bolt (olunzima kakhulu kithi): I-stud enentambo ene-hex nut yamukela ama-terminal endandatho aboshwe ocingweni. Lolu uhlobo lokuxhuma kuphela oluphatha ngokuthembekile ama-conductor angaphezu kuka-35mm², futhi yilokho esikuchazayo kuzo zonke ama-terminal okufaka ayinhloko angu-150A kanye no-200A njengokujwayelekile.
Izitifiketi Nokuhambisana Nezindinganiso: Lokho Umhloli Wakho Azokuhlola
Uma kukhona isifundo esisodwa engisifunde kanzima eminyakeni yokuqala yomsebenzi wethu wokukhiqiza, yilesi: izitifiketi azizona izihlobiso zokuzikhethela — ziyisithiyo esincane sokungena kunoma yikuphi ukuthengwa kwezimboni okungathi sína. Nakhu okudingeka ukuqinisekise kunoma yiliphi ishidi lencazelo yebhulokhi yebhulokhi yesitimela se-DIN rail busbar:
I-IEC 60947-7-1 — Lena indinganiso yamazwe ngamazwe eyisisekelo yamabhulokhi e-terminal asetshenziswa kuma-switchgear aphansi kanye nama-controlgear assemblies. Ichaza i-voltage elinganisiwe (≤1000V AC), amandla kagesi alinganisiwe, kanye — okubaluleke kakhulu — izinqubo zokuhlola isilinganiso samanje se-short-circuit (SCCR). Nge isichibiyelo sakamuva se-IEC 60947-7-1, amabhlogo wokugcina kumele manje amemezele inani lawo le-SCCR ngokucacile, okumele lihlanganiswe namadivayisi okuvikela angaphezulu.
I-UL 1059 — Okufanayo kwaseNyakatho Melika, okumboza amabhlogo okugcina afinyelela ku-1500V. Ukuhlolwa kwe-UL 1059 kuqinile kakhulu kune-IEC ezindaweni eziningana ezibalulekile: kudinga ukuhlolwa kokumelana ne-dielectric ku-voltage elinganisiwe engu-2× + 1000V (uma kuqhathaniswa ne-voltage elinganisiwe engu-2× ye-IEC), futhi kuphoqelela ukuhlolwa kokujikeleza kokushisa ku-current elinganisiwe yemijikelezo engu-50 (uma kuqhathaniswa nokuhlolwa kokuphakama kokushisa okungaguquki kwe-IEC). Ngokwe Uhlelo lwe-UL 1059 6-2024, ukubuyekezwa kwakamuva kwenezela izidingo ezithuthukisiwe zamabhulokhi okugcina okuvikelayo.
Iphothifoliyo yethu yesitifiketi njenge umenzi webhulokhi yesiteshi sebhasi i-din rail kufaka phakathi: Ukumakwa kwe-CE (ukuthobela imithetho ye-EU), ukufakwa ohlwini lwe-UL (ifayela liyatholakala uma liceliwe), ukuphathwa kwekhwalithi ye-ISO 9001:2008, ukuhlolwa kwe-SGS komuntu wesithathu, ukuthobela imithetho ye-RoHS, kanye nesimemezelo se-REACH. Konke ukuthunyelwa kufaka isitifiketi sokuhambisana nezinombolo zebhetshi ezingalandelelwa.
Kungani Kufanele Ukhethe Umkhiqizi We-Chinese DIN Rail Busbar Terminal Block?
Ngizophendula lo mbuzo ngqo ngoba amaqembu okuthenga asibuza lokhu njalo ngesonto. Imboni yezingxenye zikagesi ishintshe kakhulu eminyakeni eyishumi edlule. Amandla okukhiqiza aseShayina avale igebe lekhwalithi nabakhiqizi baseYurophu nabaseMelika — ngenkathi egcina inzuzo yezindleko ezingama-30-50% evela ekukhiqizeni okuhlanganisiwe okuqondile, hhayi ekushintsheni izinto noma ekuhlolweni.
Nakhu okushiwo ukuhlanganiswa okuqondile ekusebenzeni esikhungweni sethu: Sithela izikhunta zethu zokujova endlini. Sinyathela amabhara ethu ethusi kusuka ku-C11000 copper strip eqinisekisiwe etholakala ku-Jiangxi Copper (omunye wabakhiqizi bethusi abakhulu emhlabeni). Sisebenzisa imigqa yethu yokuhlanganisa ezenzakalelayo. Futhi sigcina ilebhu yethu yokuhlola yangaphakathi ehlonyiswe ngabahloli be-dielectric, ama-micro-ohmmeter, amakhamera okuthatha izithombe zokushisa, kanye negumbi lokuhlola impilo elisheshayo lamahora angu-500.
Lokhu kuhlanganiswa okuqondile kususa izendlalelo ezintathu ze-markup — umsabalalisi wezinto zokusetshenziswa, umhlinzeki wezingxenye ezincane, kanye ne-contract assembler — ezivame ukufakwa emananini amabhulokhi e-terminal anegama laseNtshonalanga (okufanele ngiqaphele ukuthi akhiqizwa kabanzi eShayina noma kunjalo, ngelebula ehlukile).
Kwabakhi be-OEM kanye nabakhi bephaneli abathola usizo kusuka efektri yethu ngqo, ezomnotho zihumusha kanje:

Izindlela Ezinhle Zokufaka: Lokho Ishidi Ledatha Elingakutsheli Khona
Amashidi edatha akutshela amanani e-torque kanye nobude be-wire strip. Abakutsheli ukuthi yini ngempela ehamba kabi ensimini. Nakhu esikufundile ezinkulungwaneni zokusebenzelana kokusekelwa kwamakhasimende:
I-Torque ibaluleke kakhulu kunalokho ocabanga ngakho — futhi i-torque engakafiki ezingeni elifanele ivame kakhulu ngokuphindwe kayishumi kunoku-torque engakafiki ezingeni elifanele. I-terminal yesikulufu eqiniswe ku-50% we-torque ekalwe izobonisa ukumelana kokuthintana okuphindwe kathathu kuya kahlanu kunencazelo - futhi ku-200A, lokho kumelana okwengeziwe kukhiqiza ukushisa okwanele ukuthambisa indlu ye-PA66 zingakapheli amahora okusebenza okuqhubekayo. Sithumela i-screwdriver ye-torque elinganisiwe nayo yonke isampula yokuthunyelwa e-oda lokuqala ngoba siyazi ukuthi izitolo eziningi zamaphaneli zisebenzisa ama-screwdriver aphathwayo angalinganisiwe.
Ukusetshenziswa kwe-ferrule akuyona into yokuzikhethela ngaphezu kwe-16mm². Ama-conductor ethusi aqinile angenazo izimbobo zomoya ayavuleka ngaphansi kokucindezelwa — eminye imicu iyathintana, eminye ayithinti. Indawo yokuthintana esebenzayo incishiswa ngo-20-30% uma kuqhathaniswa ne-ferrule egobekile kahle, futhi lokhu kusho ukumelana okuphezulu, izinga lokushisa eliphakeme, kanye — esimweni esibi kakhulu — nokuphuka kwemicu ngenxa yokujikeleza kokushisa. Sifaka ama-ferrule ethusi ahambisana ne-DIN 46228 kuzo zonke iyunithi zokupakisha zamabhulokhi esiphelo ezingaphezu kuka-25mm².
Amabhulokhi e-terminal e-Busbar adinga umoya opholile. Ngokungafani namabhulokhi okugcina adlulayo athwala ugesi ngendlela eyodwa yomqhubi, amabhulokhi ebhasi agxila ku-200A ngesitimela esisodwa sethusi esihamba ngobude bonke bebhulokhi. Ephanelini eligcwele kakhulu, la mabhulokhi kumele afakwe okungenani igebe lomoya elingu-10mm kuzo zonke izinhlangothi — ngoba ukushisa okukhiqizwa yi-200A kubha yebhasi engu-16mm² cishe kungama-0.75W ngesikhundla setheminali, kanti ibhulokhi enezindawo ezingu-20 ikhiqiza ama-15W njalo.

Amabhulokhi e-busbar terminal anikeza ukuminyana okuphezulu kanye nokuxhuma okulula kwezinhlelo zokusebenza ezifika ku-200A; ama-PDB adlula ngaphezu kuka-200A lapho i-radii yokugoba izintambo kanye nokushabalaliswa kokushisa kwenza indlela ehlanganisiwe ingasebenzi.
Q: Amabhulokhi e-DIN rail busbar terminal ahlala isikhathi esingakanani?
Ngaphansi kwezimo ezilinganiselwe (indawo engu-40°C, umthwalo oqhubekayo ongu-≤80%), ibhulokhi yesiteshi sebhasi yethusi efakwe kahle enezindlu ze-PA66 inokuphila komklamo kweminyaka engaphezu kwengu-20. Isici sangempela esikhawulela impilo cishe njalo siwukujikeleza kokushisa — ukunwebeka nokufinyela kwe-copper busbar (CTE: 17×10⁻⁶/K) ngokumelene ne-PA66 housing (CTE: 80×10⁻⁶/K) kukhulula kancane kancane ukuxhumana kwezikulufo phezu kwezinkulungwane zemijikelezo. Ukulungiswa kabusha kwe-torque minyaka yonke ngesikhathi sokulungiswa okuhleliwe kwandisa impilo yesevisi kakhulu.
U: Ngingayithola yini i-busbar configurations eyenziwe ngokwezifiso?
Yebo. Njengomkhiqizi okhiqiza isikhunta sangaphakathi, sivame ukukhiqiza amabhlogo esiphetho sebhasi esenziwe ngokwezifiso anamanani angewona ajwayelekile ezigxobo, izilinganiso zamanje ezixubile kubhasi elifanayo, izindawo ezikhethekile zombala zokubhala ikhodi ye-voltage, kanye nokumaka/ukulebula ngokwezifiso. Inani elincane kakhulu le-oda lokucushwa ngokwezifiso liqala kumayunithi ayi-1,000, kanti ukuncishiswa kwamathuluzi kufakiwe entengo yeyunithi.

Q: Ingabe amabhlogo e-terminal e-J-Guang ayahambisana nezesekeli ezivela kwamanye amabhrendi?
Amabhulokhi ethu esiteshi sesitimela se-DIN asebenzisa iphrofayili yesitimela ye-TS-35 ejwayelekile embonini kanye nesikhala esijwayelekile somugqa ophakathi nendawo (ngokuvamile u-6mm, 8mm, noma u-10mm kuye ngochungechunge). Ama-bracket okugcina, ama-partition plate, kanye ne-marking strips ngokuvamile ahambisana nemikhiqizo emikhulu (i-Weidmüller W-Series, i-Phoenix Contact UK-Series) ngoba lezi zilinganiso ziyizindinganiso zemboni - yize sihlala sincoma ukuqinisekisa ukuhambisana kwemishini nesampula ngaphambi kokuzibophezela kuma-oda amakhulu.
Kungani i-J-Guang Izidingo Zakho Ze-DIN Rail Busbar Terminal Block
Besilokhu sikhiqiza amabhlogo e-terminal kanye nezixhumi kusukela ngo-2010 esikhungweni sethu eNingbo, eShayina — iminyaka eyi-15 sigxile kulesi sigaba somkhiqizo. Asiyona inkampani yokuhweba ethola imali ezimbonini ezingahleliwe; siyifektri.
