Iyini i-Molded Case Circuit Breaker

Ezweni lamasistimu kagesi namasekhethi, ukuphepha kubaluleke kakhulu.Isisetshenziswa esibalulekile esidlala indima ebalulekile ekugcineni ukuphephaI-Molded Case Circuit Breaker (MCCB).Njengoba iklanyelwe ukuvikela amasekhethi ekulayishweni ngokweqile noma kumasekhethi amafushane, le divayisi yokuphepha idlala indima ebalulekile ekuvimbeleni ukulimala kwamasistimu kagesi.

Ngakho-ke, yini ngempela i-circuit breaker yecala elibunjiwe?Eyaziwa nangokuthi i-MCCB, iyidivayisi yokuvikela isekethe ezenzakalelayo esetshenziswa kuwo womabili amasistimu anamandla kagesi aphansi kanye naphezulu.Umsebenzi wayo oyinhloko ukunqamula amandla ngokuzenzakalelayo lapho kutholwa iphutha noma isimo esidlulele.Lesi senzo esisheshayo sisiza ukuvimbela noma yimuphi umonakalo noma izimo eziyingozi ezingase zibe umphumela wephutha likagesi.

Ama-MCCBsziyizingxenye ezibalulekile ezinhlobonhlobo zezinhlelo zokusebenza ezisukela ezimbonini nasezindaweni zokuhweba kuya ezindaweni zokuhlala.Zivame ukusetshenziswa ezinhlelweni zokusabalalisa amandla, izikhungo zokulawula izimoto kanye nama-switchboards.Ukuhlukahluka kwazo kuzivumela ukuthi zinikeze ukuvikeleka kwamasekhethi ahlukahlukene, okuwenza abe yingxenye ebalulekile yokuphepha kukagesi.

Enye yezinzuzo eziyinhloko zama-MCCB amandla awo okuphatha imisinga ephezulu.Uma kwenzeka ukugcwala ngokweqile noma ukujikeleza okufushane, i-MCCB iphazamisa ngokushesha ukugeleza kwamanje, ivikela okokusebenza kukagesi okuxhunyiwe futhi ivimbele noma yimuphi umonakalo ongaba khona.Lesi sici asisizi nje kuphela ukuvikela uhlelo lukagesi kodwa futhi sivimbela noma yiziphi izingozi zomlilo ezibangelwa ukushisa ngokweqile okubangelwa izimo ezidlulele.

Ukwengeza, ama-MCCB kulula ukusebenza nokuyigcina.Uma iphutha selisuliwe, i-MCCB ingasethwa kabusha kalula ukuze ibuyisele amandla ohlelweni ngaphandle kokungenelela okwenziwa ngesandla.Lokhu kulula akugcini nje ukugcina isikhathi kodwa futhi kuqinisekisa ukusabela okusheshayo kunoma yimaphi amaphutha kagesi, ukunciphisa isikhathi sokuphumula nokugcina ukusebenza okuqhubekayo kwesistimu kagesi.

Esinye isici esibalulekile se-MCCB ukwethembeka kwayo.Lawa madivayisi aklanyelwe ukunikeza isivikelo esingaguquki nesiqinile kumaphutha kagesi ngokuhamba kwesikhathi.Ikhono labo lokusingatha imithwalo eminingi kagesi kanye nezimo zemvelo kwenza kube ukukhetha okuthembekile kokuqinisekisa ukuphepha kwesifunda nobuqotho.

Ngokufigqiwe,I-Molded Case Circuit Breakers (MCCBs) zibalulekile ekuqinisekiseni ukuphepha nokuvikelwa kwamasekethe.Ikhono labo lokusabela ngokushesha ekulayisheni ngokweqile noma ezimeni zesifunda esifushane, kuhambisana nokwethembeka kanye nokusebenza kalula, kubenza babe yingxenye ebalulekile yanoma yiluphi uhlelo lukagesi.Kungakhathaliseki ukuthi kusezimbonini, ezentengiselwano noma ezindaweni zokuhlala, ama-MCCB adlala indima ebalulekile ekuvimbeleni ukulimala kwezinto zikagesi, ukunciphisa isikhathi sokuphumula futhi okubaluleke kakhulu, ukuvikela izimpilo.Ukubaluleka kwama-MCCBs ekuphepheni kukagesi akukwazi ukweqiwa ngenxa yekhono lawo lokuhlinzeka ngokuvikelwa kwesekethe okusebenzayo nokuqinile.
