Ezinhlelweni zokusabalalisa amandla, ukukhetha okusebenzayo nokunembayo kwezintambo ezinephutha kubalulekile ukuze kuqinisekiswe ukuphakelwa kukagesi okungaphazamiseki.Ii-parallel resistor device, eyaziwa nangokuthi i-parallel resistor cabinet, iyithuluzi lokukhetha umugqa elibanzi elifakwe ngokuhambisana nendawo emaphakathi yesistimu futhi lixhunywe kukhoyili yokucindezela i-arc.Ngokusebenza kwayo okuyingqayizivele, le mishini ithuthukisa kakhulu ukunemba kokukhethwa komugqa wamaphutha, ngaleyo ndlela ikhulise ukusebenza kahle kokusebenza futhi inciphise isikhathi sokuphumula.
Amadivayisi aphikisanayo adlala indima ebalulekile ekukhethweni komugqa onephutha ezinhlelweni zokusabalalisa amandla.Ngokufakwa ngokuhambisana nokungathathi hlangothi kwesistimu, kusiza ukudlulisela iphutha kude nemigqa enempilo.Idivayisi ixhunywe kukhoyili yokucindezela i-arc, ihlukanise ngempumelelo ingxenye enephutha kuyo yonke igridi.Lokhu kusetha okuhlakaniphile kuqinisekisa ukuthi imigqa enephutha kuphela ebonwayo futhi ehlukanisiwe, okuvumela amandla ukuthi ageleze ngaphandle kokuphazamiseka emigqeni enempilo.
Esinye sezici ezivelele ze-parallel resistor integrated line device yokukhetha ikhono lokuthola ukunemba kwe-100% yokukhetha umugqa ohlelweni lwekhoyili yokucindezela i-arc.Ngokungafani nezindlela ezivamile ezithembele ekuhloleni okwenziwa ngesandla noma ekuhlakanipheni kobuhlakani, ukwakheka okukhaliphile kwedivayisi yokumelana ne-parallel iqinisekisa umzila onephutha onembile.Ngokukhomba ngokunembile isigaba esinephutha, ama-opharetha egridi angasebenza ngokushesha ukuze anciphise isikhathi sokuphumula futhi abuyisele amandla ngendlela efanele.
Idivayisi ye-shunt resistor iqukethe i-resistor esekelwe phansi efakwe kukhabethe eliphikisayo.I-ground resistor yamukela futhi ihlakaze i-fault current, iwususa kude nolayini oxhunywe kukhoyili yokucindezela i-arc.Lokhu kwakhiwa okuqinile kuqinisekisa ukuhlonza okusheshayo nokunembile kwemigqa enephutha ngaphandle kokulimaza lonke uhlelo lokusabalalisa.Ukwengeza, amakhabethe okumelana ahlinzeka ngendawo ephephile futhi elawulwayo yalezi zingxenye ezibalulekile, ngaleyo ndlela andise impilo yabo yesevisi nokusebenza.
Ngaphezu kwezinzuzo zobuchwepheshe, amadivaysi e-parallel resistor nawo anezinzuzo ezingabizi kakhulu.Ngokunika amandla ukukhetha okunembile kwezintambo, idivayisi isiza ukunciphisa isikhathi nomzamo odingekayo wokuhlonza iphutha nokuxazulula inkinga.Lokhu kusho izinhlelo zokulungisa ezithuthukisiwe kanye nezindleko ezincishisiwe zabasebenzi kubasebenzisi begridi.Ukwengeza, amadivaysi aphikisanayo afanayo asiza ukunciphisa umthelela wokucisha ngokuhlukanisa ngokushesha izingxenye ezinephutha, ngaleyo ndlela andise ukwaneliseka kwamakhasimende futhi athuthukise ukwethembeka kwesistimu iyonke.
Kafushane, amadivayisi we-shunt resistor ayingxenye ebalulekile yezinhlelo zokusabalalisa amandla.Ikhono layo lokuthola ukunemba kokukhethwa kwemigqa engu-100%, kuhlanganiswe nokwakhiwa kwayo okumazombezombe kanye nokusebenza kahle kwezindleko, kuyenza ibe ithuluzi elibalulekile kubaqhubi begridi.Ngokufaka lesi sisetshenziswa, ama-opharetha angakhuphula ukusebenza kahle kokuhlonza amaphutha, anciphise isikhathi sokuphumula, futhi ekugcineni anikeze ugesi othembekile, ongaphazamiseki kubasebenzisi bokugcina.
