I-Low-voltage circuit breaker yohlobo lwe-low-voltage, ingeyomshini oyinhloko wokusabalalisa, iyisihlukanisi sesekethe esinamandla amakhulu aphansi, esinamandla amakhulu okuphuka kwesiyingi esifushane kanye nokuzinza okuphezulu okuguquguqukayo, izici zokuvikela izigaba eziningi, ikakhulukazi ezisetshenziswa ku-10kV/380V. i-power transformer 380V side, esetshenziselwa ukusabalalisa amandla nokuvikela imigqa nemishini yamandla, Ngokugcwala ngokweqile, isifunda esifushane, ngaphansi kwe-voltage, isisekelo sesigaba esisodwa kanye nomunye umsebenzi wokuvikela amaphutha nomsebenzi wokuzihlukanisa.I-Universal low-voltage circuit breaker grade grade grade grade grade rated yamanje ivamise ukuba ngu-200A ~ 6300A, umthamo wokuphuka kwesekethe emfishane ngu-40 ~ 50kA, enezindlela ezintathu zokusebenza ezenziwa ngesandla, i-lever kanye nezikagesi, umkhawulo womthamo ophezulu wokucisha we-universal circuit breaker esetshenziswayo. indlela yokusebenza yokugcina amandla ukuthuthukisa isivinini sokucisha.I-universal low-voltage circuit breaker ikakhulukazi yakhiwe isistimu yokuxhumana, indlela yokusebenza, idivayisi yokukhishwa yamanje, idivayisi yokukhishwa kwe-shunt kanye nedivayisi yokukhulula engaphansi kwe-voltage, izesekeli, uhlaka, isekethe yezintambo zesibili nezinye izingxenye.Zonke izingxenye zifakwe insulated futhi zifakwe esisekelweni sensimbi se-insulation liner.Amadivayisi ahlukene okukhipha kanye nezinsiza kungahlanganiswa ukwenza ama-circuit breaker anezici zokusebenza ezikhethiwe, ezingakhethi noma eziphambene.Isilawuli kude singenzeka ngoxhumana nabo abasizayo.Kunezinhlobo eziningi namamodeli we-universal low-voltage circuit breaker, izinhlobo eziningi, nokusebenza okuhlukile.Ngaphansi kwezimo ezijwayelekile, ingasetshenziswa njengokuguqulwa okungajwayelekile komugqa.
Igobolondo lepulasitiki lohlobo lwe-low-voltage circuit breaker (okubizwa ngokuthi i-plastic-case type low-voltage circuit breaker) ingeyezinto zikagesi ezisabalalisa okwesibili.Ibonakala ngezinhlobonhlobo zezesekeli zingahlanganiswa zibe imisebenzi ehlukene ye-breaker circuit, isakhiwo esiyisisekelo sakhiwe ngegobolondo elivaliwe elivaliwe (eminye imikhiqizo igobolondo elisobala), indlela yokusebenza, ukuthintana kanye nesistimu yokucisha i-arc, ukukhululwa kazibuthe ezishisayo nezinye izesekeli. 5 izingxenye eziyisisekelo.Izingxenye eziyisisekelo zifaka idivayisi yokukhishwa yamahhala, idivayisi yokukhishwa kwe-thermal, othintana naye oyinhloko, inkinobho yokuhlola, isango lokucisha i-arc kanye nendlela yokusebenza.Izesekeli ezahlukene zingakhethwa ngokwezidingo ukuhlangabezana nezidingo ezahlukene zokusebenza.
Ama-circuit breaker amancane, aziwa nangokuthi ama-modular miniature circuit breaker, asetshenziswa kabanzi emabhokisini okusabalalisa amandla ekugcineni kwemigqa yokusabalalisa i-terminal, amabhokisi okusabalalisa izibani kanye namanye amasethi aphelele amabhokisi kagesi, imigqa yokusabalalisa, ama-motor, amasekhethi okukhanyisa nezinye izinto zikagesi. ukusatshalaliswa, ukulawula kanye nokuvikela (isifunda esifushane, ukugcwala ngokweqile, ukuvuza).I-micro circuit breaker iqukethe indlela yokusebenza yesibambo, idivayisi yokukhishwa kwe-thermal, idivayisi yokukhishwa kuka-electromagnetic, isistimu yokuxhumana, isiphazamisi se-arc nezinye izingxenye, zonke ezibekwe endaweni evikelayo.Izici zesakhiwo usayizi wohlaka we-modular (ukuphindaphinda kwe-9mm) kanye nojantshi wokufaka, ububanzi bemodulus ye-single-pole (1P) i-circuit breaker yomkhiqizo wamanje ngu-18mm (27mm), ububanzi be-single- i-pole (1P) ye-circuit breaker yomkhiqizo wamanje omncane ngu-17.7mm, ukuphakama kwentamo eyi-convex ngu-45mm, futhi ukufakwa kusebenzisa ujantshi ojwayelekile ongu-35mm.I-slot yokufaka ngemuva kwe-circuit breaker kanye nesiqeshana sokubopha esinentwasahlobo kusetshenziselwa ukubeka nokuqaqa kalula.Kunezinhlobo ze-unipolar + neutral (uhlobo lwe-1P+N), i-unipolar (1P), ezimbili (2P), ezintathu (3P) kanye nezinhlobo ezine (4P).
