Ii-OEM zePaneli yoLawulo yaseJamani Tshintshela kwiiBloko zeTerminal zeDouble-Deck ze-480V PDU Compact Wiring
I-IEC 60947-7-1 Isiqendu 5.3 ekusebenzeni: Kutheni "i-UL-Listed" ingalingani ne "IEC 60947-7-1 Compliant" kwizicelo ze-480V
Xa ii-OEM zephaneli yokulawula yaseJamani zikhupha iinkcukacha zokuthenga zeebhloko zesiphelo ezisetyenziswa kwiiyunithi zokusasazwa kwamandla ze-480V, ndibone ukudideka okuphindaphindiweyo: ingcamango yokuba uluhlu lwe-UL luyahlangabezana nemfuneko yokuthobela i-IEC 60947-7-1. Akunjalo. Ezi ziinkqubo ezimbini ezahlukeneyo zesatifikethi ezineenkqubo zovavanyo ezahlukeneyo, imigangatho eyahlukeneyo yesalathiso, kunye nokuma okusemthethweni okwahlukileyo kwiimarike zaseYurophu naseMntla Melika. Ukuqonda umahluko kubalulekile kuye nabani na ochaza iibhloko zesiphelo kwizicelo ze-480V PDU.
UL 1059, umgangatho we-Underwriters Laboratories weebhloko zesiphelo, uqinisekisa ukusebenza kokhuseleko ngokuyintloko ngovavanyo lwangoku olufutshane kunye novavanyo lokumelana ne-dielectric kwinqanaba lecandelo. I-IEC 60947-7-1, ngokwahlukileyo, ngumgangatho osekelwe ekusebenzeni oquka uvavanyo lokunyamezela koomatshini - ngokukodwa, imijikelo yokusebenza eyi-1,000 kumjikelo wokusebenza olinganiselweyo - uvavanyo lokunyuka kobushushu phantsi komthwalo, kunye neemfuno ezithile zokuqhekeka kunye nokususwa ezidityaniswe ne-voltage yokusebenza kunye nenqanaba lokungcola. Ibhloko yesiphelo ephethe kuphela ukuqatshelwa kwe-UL 1059 ayikavavanywa ngokuyimfuneko kwi-IEC 60947-7-1 Isigaba 5.3 seemfuno zokunyamezela koomatshini kunye nokunyuka kobushushu. Kwizicelo ze-480V apho uxinzelelo lobushushu oluqhubekayo oluvela kukuhamba kombane okuqhubekayo luyi-driver eyaziwayo yokusilela, lo mahluko unokuthetha umahluko phakathi kwebhloko yesiphelo esebenza ngokuthembekileyo iminyaka eli-15 kunye neyo ephuhlisa ukusilela kokudinwa kobushushu ngaphakathi kwemizuzu emi-5.
Kwii-OEM zephaneli yokulawula yaseJamani, isiphumo esisebenzayo sokuchaza kuphela iibhloko zesiphelo "ezidweliswe kwi-UL" kukuba imveliso efakiweyo isenokungahlangabezani neemfuno zokunyamezela koomatshini ezifunekayo kwisicelo sokusetyenziswa kokugqibela. Ukuba iinkcukacha zibhekisa kwi-IEC 60947-7-1 — esetyenziswa kakhulu ziinkcukacha zoomatshini baseJamani — icandelo elidweliswe kwi-UL kuphela lidala umsantsa wokuthobela umthetho obonakala ngexesha lokuhlolwa okuzayo komakhi wephaneli okanye uphicotho lobuchwephesha lomthengi wokugqibela. Ndibone esi sithuba sibangela ukulibaziseka kweprojekthi kweeveki ezi-4-6 xa umakhi wephaneli waseJamani wafumanisa ukuba ibhloko yesiphelo abayithandayo, ngelixa idweliswe kwi-UL, ayinakubhalwa njenge-IEC 60947-7-1 ehambelana nesicelo se-480V.
Ii-4.8mm Creepage Distance Mechanics kwi-5.2mm Pitch: Kutheni le Jiometri iyimpendulo yobunjineli kwi-IEC 60664-1 Pollution Degree 2 Iimfuneko zeNkqubo ze-480V
Ubudlelwane phakathi kwesithuba sepitshi kunye nomgama wokuqhekeka kuyilo lweebhloko zesiphelo bulawulwa yifiziksi yokuqhekeka komphezulu kumphezulu wokugquma. Umgama wokugquma yeyona ndlela imfutshane phakathi kwamacandelo amabini okuqhuba alinganiswa kumphezulu wezinto zokugquma - kwaye kwinkqubo ye-480V AC, i-IEC 60664-1 ichaza umgama omncinci wokugquma we-4.0mm kwiqondo lokungcola 2, olu ludidi oluqhelekileyo lwezinga lokungcola kwiiphaneli zolawulo zemizi-mveliso ezivaliweyo. Kwinqanaba le-5.2mm, umgama ophakathi ukuya embindini phakathi kweepali ezikufutshane kwibhloko yesiphelo eqhelekileyo yi-5.2mm, kodwa umgama wokwenyani wokugquma - indlela ecaleni komphezulu wendlu yokugquma phakathi kweendawo zokugquma ezikufutshane - wongezwa yijometri yomqobo wokugquma phakathi kweepali.
KwaJ-Guang's Uthotho lwePCT-211 Iibhloko zesiphelo ezineedekhi ezimbini, umgama wokusika olinganisiweyo kwi-pitch ye-5.2mm yi-4.8mm, ebonelela ngomda wokhuseleko we-20% ngaphezulu kwe-IEC 60664-1 ubuncinci be-4.0mm ekusebenzeni kwe-480V. Lo mda awuyongozi — sisiphumo sokhetho oluthile lwejometri kuyilo lwebhloko yokuthintela ukugquma oludibanisa malunga ne-0.6mm yendlela yomphezulu esebenzayo xa kuthelekiswa nomlinganiselo othe tye phakathi kweepali. Intsingiselo esebenzayo yalo mda we-20% kukuba Uthotho lwePCT-211 ihlala ihambelana neemfuno ze-IEC 60664-1 zokuqhekeka nokuba zikwimeko yongcoliseko lwe-degree 3 (apho ungcoliseko oluqhubayo olufana nothuli okanye ukufuma lunokubakho ngamaxesha athile), okoko nje iphaneli ebiyelweyo inika umlinganiselo wokhuseleko we-IP54 okanye ophezulu.
Eyona nto ndiyifumana ingaqondwa kakuhle kwiinkcukacha zokuthengwa kweebhloko zesiphelo kukuthatha ingcamango yokuba ixabiso lepitch lodwa limisela ukuthotyelwa kwe-creepage. Impazamo eqhelekileyo yeenkcukacha endiyibonileyo kukuchaza ibhloko yesiphelo ngepitch yodwa ngaphandle kokuqinisekisa ukuba umgama we-creepage uhlangabezana neemfuno zeklasi ye-voltage yokufakelwa okuthile. Kwinkqubo ye-480V, umgama omncinci we-creepage we-4.0mm kufuneka uqinisekiswe ngedatha yovavanyo okanye ngohlalutyo oluneenkcukacha lwejometri - ayinakuthathwa kwixabiso lepitch. Uthotho lwe-PCT-211 luka-J-Guang lubonelela ngedatha yovavanyo lomgama we-creepage njengoxwebhu oluqhelekileyo lwebhetshi nganye yemveliso, ecelwa rhoqo yi-OEMs yaseJamani njengenxalenye yenkqubo yabo yokuhlola engenayo ukuqinisekisa ukuba imveliso ehanjiswayo ihlangabezana nomgama we-creepage ochaziweyo.

Kwizinga labasebenzi baseJamani le-EUR 40 ngeyure, oku kuthetha ukonga abasebenzi kwe-EUR 24 ngePDU nganye. Kwizinga lemveliso lee-PDU ezingama-200 ngonyaka, ukonga abasebenzi ngonyaka yi-EUR 4,800 - eli lixabiso elibalulekileyo ngokuchasene nomahluko weendleko zepali nganye phakathi kweebhloko zohlobo lweskrubu kunye neebhloko zesiphelo zokutyhala kwiibhloko zemitha zaseJamani ezidla ngokuodolwa.
Icandelo lesibini letyala lezemali kukususa ukusilela kokukhuhla izikrufu, eyona ndlela ixhaphakileyo yokusilela kwiibhloko zesiphelo zohlobo lweskrufu kwiindawo zoshishino. Iibhloko zesiphelo zohlobo lweskrufu kwiiphaneli zolawulo lwezimboni ziphantsi kokukhululeka kwezikrufu okubangelwa kukukhuhla - into esekelwe kwifiziksi apho ukujikeleza kobushushu kunye nokukhuhla koomatshini kubangela ukuba isikrufu sibuyele umva kancinci kancinci kwindawo yaso eqinisiweyo, sidale uqhagamshelo oluxhathisayo oluvelisa ubushushu bendawo kwaye ekugqibeleni lunokubangela ukusilela koqhagamshelo okanye umlilo. Kwiiphaneli zolawulo lwezimboni zaseJamani, apho ukukhuhla okuvela kwiimoto, iicontactors, kunye nezinye izixhobo kuyinto eyaziwayo kwindalo, iindleko zokugcina ukulungisa ukusilela kokukhuhla izikrufu - kubandakanya ixesha lokuxilonga, umsebenzi ophinda uguqule, kunye nexesha lokungasebenzi kwemveliso - zihlala ziphantsi kwiinkcukacha zokuthenga ezigxila kuphela kwixabiso lokuqala ngeyunithi nganye. Iibhloko zesiphelo zokungena ziyayisusa le ndlela yokusilela ngokupheleleyo kuba indlela yentwasahlobo ayikhululeki phantsi kokukhuhla okanye ukujikeleza kobushushu.
Kutheni iSatifikethi se-Dual CE + UL 1059 sidala indlela yokuthobela uxwebhu olunye kwiiphaneli ezenzelwe iiprojekthi zaseYurophu naseMntla Melika
Kwii-OEM zephaneli yokulawula zaseJamani ezithumela kwamanye amazwe kwiimarike zaseYurophu naseMntla Melika, umthwalo wokuthobela imithetho yeebhloko zesiphelo uhlala uphindaphindwa: iipakeji zamaxwebhu ezahlukeneyo zokumakishwa kwe-CE ngokwe-Low Voltage Directive (2014/35/EU) kunye noluhlu lwe-UL ngokwe-UL 1059, kunye neengxelo zovavanyo ezahlukeneyo, izatifikethi zokuthobela imithetho, kunye neemfuno zovavanyo lokujonga oluqhubekayo. Ixabiso lokugcina isatifikethi esiphindwe kabini - kwiimali zovavanyo, ulawulo lwamaxwebhu, kunye nokujonga okuqhubekekayo kokuthobela imithetho - lihlala likhankanywa ngabakhi bephaneli baseJamani njengobunzima bokuthenga abangathanda ukubususa ngokuhlanganisa umthengisi omnye weebhloko zesiphelo onokubonelela ngazo zombini izatifikethi.
Uthotho lwe-PCT-211 luka-J-Guang luneempawu ze-CE (eziqinisekisiweyo ngokuchasene ne-IEC 60947-7-1) kunye nokwamkelwa kwe-UL 1059 njengomgangatho, oko kuthetha ukuba ulungiselelo olunye lwemveliso luyahlangabezana neemfuno zokuthobela i-terminal block kwiimarike zaseYurophu naseMntla Melika. Kwii-OEM zephaneli zaseJamani ezibonelela ngeepaneli zolawulo kwiiprojekthi zaseMntla Melika ngokusebenzisa umakhi wepaneli odweliswe kwi-UL, olu qinisekiso lubini lususa isidingo sokufumana ii-SKU ze-terminal block ze-CE kuphela kunye ne-UL kuphela - nto leyo eyenza kube lula ukubhalwa kwezinto, inciphise inani lababoneleli abafanelekileyo ekufuneka balawulwe kwaye bahlolwe, kwaye inciphise umngcipheko weempazamo zeenkcukacha kwinqanaba lokukhetha izinto xa uhlobo lwesiqinisekiso olungalunganga lu-odolwe ngempazamo.
Inzuzo yoxwebhu lwesatifikethi esiphindwe kabini ibaluleke ngokulinganayo kwimisebenzi yokuthengwa kweprojekthi. Xa iphaneli ye-OEM yaseJamani iphendula kwithenda yeprojekthi yaseMntla Melika efuna izinto ezidweliswe kwi-UL kunye neepakeji zamaxwebhu ezithunyelwe njengenxalenye yethenda, ukufumaneka kwedatha yovavanyo lwe-UL 1059 kunye namaxwebhu okuqatshelwa kwe-UL ochungechunge lwe-PCT-211 kususa ukukhangela kweqela lokuthenga enye indlela ehambelanayo.

Xa ndicebisa ii-OEM zephaneli yokulawula yaseJamani malunga nokuthengwa kweebhloko zesiphelo, ndicebisa ukuba kuchazwe umgangatho kunye neemfuno zovavanyo ezithile, kungekhona uphawu lwesatifikethi kuphela. Kwizicelo ze-480V, inkcazo kufuneka ibhekisele kwi-IEC 60947-7-1 ithathelwe ingqalelo ngokukodwa kwiCandelo 5.3 (ukunyamezela koomatshini) kunye neCandelo 6.2 (ukunyuka kobushushu phantsi komthwalo), kwaye kufuneka ifune idatha yovavanyo lomgama we-creepage njengemfuneko yoxwebhu lokuhambisa. Eli nqanaba lokucaciswa kwinkcazo lisusa ukungacaci okukhokelela ekulibazisekeni kokuthengwa kwaye liqinisekisa ukuba iibhloko zesiphelo ezihanjiswayo zifanelekile ngokwenene kwisicelo - kungekhona nje "ukuqinisekiswa" komgangatho ongenakugubungela iiparameter zokusebenza ezifanelekileyo.
Uthotho lwe-PCT-211 luyimpendulo kaJ-Guang kulo mceli mngeni weenkcukacha: ibhloko yesiphelo esineedekhi ezimbini eqinisekisiweyo kwi-IEC 60947-7-1 kunye ne-UL 1059, kunye nedatha yovavanyo lomgama we-creepage ekhoyo kwibhetshi nganye yemveliso, kunye nenkqubo yokuhlola ekwinkqubo enika abakhi beephaneli baseJamani ukuhambelana kwebhetshi ukuya kwibhetshi abayifunayo ukuze bagcine umgangatho wemveliso kwinqanaba. Ukuze ufumane ulwazi oluthe kratya malunga neenkcukacha zothotho lwe-PCT-211 kunye nephakheji yamaxwebhu, ndwendwela Ikhathalogu yemveliso yebhloko yesiphelo sikaJ-Guang okanye uqhagamshelane neqela lobuchwephesha le-J-Guang ngokuthe ngqo.
Umxholo wesicelo esisebenzayo sothotho lwe-PCT-211 kwizicelo ze-480V PDU uquka iimeko ezahlukeneyo zokusetyenziswa apho indibaniselwano yoqwalaselo lwe-double-deck kunye ne-5.2mm pitch geometry inika inzuzo egqibeleleyo kunezinye iindlela ze-single-deck. Kwiiphaneli zokusasazwa kwe-motor feeder — apho iisekethe ezininzi zeemoto zihanjiswa ukusuka kwi-busbar eqhelekileyo ukuya kwi-motor drives nganye — inzuzo yoxinano lweentambo zoqwalaselo lwe-double-deck ibonakala kakhulu. Iphaneli ye-motor feeder eya kufuna i-DIN rail assembly ye-400mm ebanzi kunye neebhloko zesiphelo se-single-deck ingancitshiswa ibe yi-250mm ebanzi kunye neebhloko ze-double-deck, nto leyo eguqulela ngokuthe ngqo kwi-panel form factor encinci kunye nexabiso eliphantsi lezinto ezisetyenziswayo kwi-panel enclosure.
Kwabakhi beephaneli zaseJamani ababonelela ngeephaneli zolawulo kwishishini lokutya neziselo, iimfuno zococeko zesicelo zenza ukuba kubekho ingqwalasela eyongezelelweyo. Iindawo zokucubungula ukutya neziselo zifuna iiphaneli zolawulo ezineendawo zangaphandle ezigudileyo (ukuthintela ukuqokelelana kweebhaktheriya) kunye novavanyo lokhuseleko lwe-IP65 okanye ngaphezulu kwiindawo zangaphandle. Ijiyometri yezindlu zochungechunge lwe-PCT-211 yenzelwe ezi mfuno engqondweni: iprofayili yezindlu ezigudileyo zoluhlu lwe-PCT-211 ivumela ukucocwa okulula, kwaye olu luhlu lufumaneka ngezigqubuthelo ezicacileyo ezikhethiweyo ze-IP65 ezigcina amandla okuqinisekisa ngokubonakalayo imeko yokuphela kwentambo ngelixa zibonelela ngokhuseleko lwe-IP65 kuqhagamshelo lombane. Ii-OEM zokutya neziselo zaseJamani zihlala zichaza olu lungiselelo lwezikhululo zolawulo lwepaneli kwiindawo zokucubungula ezimanzi.
Esinye isicelo apho ulungiselelo lwe-double-deck yochungechunge lwe-PCT-211 lubonelela ngenzuzo ebalulekileyo kukwiiphaneli zokusasazwa kwe-solar inverter. Ukufakelwa kwe-solar inverter eJamani nakwezinye iimarike zaseYurophu kuqhubeka kucaciswa ngeenkqubo zebhetri yokugcina ezidibeneyo, ezifuna umthamo owongezelelweyo wesekethe kwiphaneli yokusasazwa. Ukongeza lo mthamo kwiphaneli ekhoyo yedekhi enye kufuna ulwandiso lwephaneli okanye uyilo olutsha olunezixhobo ezinoxinano oluphezulu. Ulungelelwaniso lwe-double-deck yochungechunge lwe-PCT-211 lubonelela ngomthamo owongezelelweyo wesekethe ngaphakathi kwe-footprint yephaneli ekhoyo, ngaphandle kolwandiso lwephaneli okanye ukutshintshwa kwe-enclosure. Abafakeli belanga baseJamani abachaze uthotho lwe-PCT-211 kolu setyenziso baxela iindleko zokuphucula iphaneli eziphantsi ngama-40-50% kuneendleko zolwandiso lwephaneli okanye ukutshintshwa ngezixhobo zedekhi enye.
Uthotho lwe-PCT-211 lukaJ-Guang lwenziwa kwiziko lenkampani iNingbo phantsi kwemigangatho yolawulo lomgangatho we-ISO 9001. Kwii-OEM zaseJamani ezifuna utyelelo lokuhlolwa kwefektri okanye umgangatho njengenxalenye yenkqubo yazo yokufaneleka kubathengisi, iqela lobuchwephesha likaJ-Guang linokulungiselela utyelelo kwiziko kwindawo yemveliso yaseNingbo. iwebhusayithi esemthethweni ibonelela ngolwazi loqhagamshelwano lokuhlela iingxoxo zobugcisa kunye namalungiselelo okutyelela ifektri. Ngeenkcukacha zobugcisa, iifayile ze-CAD ezinokukhutshelwa, kunye nokucwangciswa kwesicelo sesampulu, icandelo lekhathalogu yemveliso Iwebhusayithi ye-J-Guang ibonelela ngokufikelela ngokuthe ngqo kumaxwebhu obuchwephesha kuzo zonke iimodeli ze-PCT series terminal block.
