Iibhloko zokusasazwa kwamandla (PDB) zeereli ze-DIN
Weidmuller diibhloko zokusasazwa kweengcingo ezinqamlezileyo ukusuka kwi-1.5 mm² ukuya kwi-185 mm² - Iibhloko zokusasazwa ezixineneyo zokuqhagamshela ucingo lwe-aluminiyam kunye nocingo lobhedu.
Iibhloko zokusasazwa kwesigaba (PDB) kunye neebhloko zokusasazwa kwesakhelo ukuze kusasazwe okunokwenzeka
Iibhloko zokucinezela kunye neebhloko zokusasazwa kwamandla (PDB) ze-DIN rail zifanelekile ukuqokelela nokusasaza amandla kwiibhokisi zokusasazwa ezincinci kunye neswitchgear. Uyilo oluncinci lweebhloko zokucinezela amandla luvumela ukuba kubekho uxinano olucacileyo noluphezulu lweentambo. Iibhloko zamandla zikhuselekile kuzo zonke iicala ngokuhambelana ne-EN 50274 kwaye ukumelana ne-short-circuit ngokuhambelana nomgangatho ophezulu we-SCCR (200 kA) kukwaqinisekisa umgangatho ophezulu wokhuseleko.
Ngenxa yokwambathiswa okukhethekileyo komzimba wobhedu, ii-conductors ze-copper wire, i-aluminium wires kunye ne-flat conductors zinokudityaniswa kwi-phase distribution block. Ukuvunywa ngokwe-VDE, UL, CSA kunye ne-IEC kwenza kube lula ukusetyenziswa kwezinye iinkqubo zoshishino nakwiimarike zamazwe ngamazwe.
Uqhagamshelo lweengcingo zobhedu kunye neze-aluminiyam
Umbindi wobhedu webhloko yokusasazwa kunye nophahla lwayo olukhethekileyo, kunye nezikrufu ezineehexagonal, kuvumela uqhagamshelo lweengcingo zobhedu kunye nezealuminiyam. Zombini uyilo lwe-conductor olujikelezileyo nolunesimo secandelo lunokuqhagamshelwa kwibhloko yokusasazwa kwamandla (PDB) kwi-DIN rail. Uqhagamshelo lwee-flat conductors lunokwenziwa nakwezinye iibhloko zokusasazwa ezinokubakho.
Iibhloko zokusasazwa ezinokubakho phakathi komnye nomnye iibhulorho
Iibhloko zokusasazwa kwamandla eWPD (PDB) ezinoqhagamshelo lwezikrufu zinokuqhagamshelwa ngokulula nangokulula ngebhulorho yobhedu ethe tyaba. Ukuphindaphindwa kabini okanye ukuphindwe kathathu kweendawo zoqhagamshelo kwicala eliphumayo kunokufezekiswa. Ngenxa yesi sizathu, iibhloko zesiphelo sombane zinokubotshelelwa kunye ukuze kubekho uzinzo olongezelelekileyo loomatshini kwireyile ye-DIN.
Ibhloko yokusasazwa okuncinci
Uyilo olukhethekileyo lwezitebhisi luvumela ubungakanani obuncinci beebhloko zokusasazwa kweWPD (PDB). Xa kuthelekiswa nokuseta okuqhelekileyo, ukonga indawo kwenziwa ngaphandle kokulahleka kokucaca ngaphakathi kwikhabhinethi.
Umzekelo, ucingo olunye olunecandelo elinqamlezileyo eliyi-95 mm² kunye neentambo ezine ezinecandelo elinqamlezileyo eliyi-95 mm² zinokudityaniswa kububanzi obuyi-3.6 cm kuphela, ubude obuncinci bube ziisentimitha ezisixhenxe.
Ukwahluka kwemibala kuyo yonke into enokwenzeka
Iibhloko zesiphelo ezinemibala ziyafumaneka ukuze kufakwe iintambo ezicacileyo kunye nokufakelwa ikhabhinethi yeswitchgear. Umbala oluhlaza okwesibhakabhaka njengebhloko yesiphelo se-N kunye noluhlaza kwibhloko yesiphelo se-PE (esemhlabeni). Ngokuxhomekeke kwibhloko yokusasazwa kwamandla kunye nokusetyenziswa kwayo, intambo yesigaba inokukhethwa phakathi kobomvu, omnyama, omdaka kunye nongwevu.
