Uyini umehluko phakathi kwe-circuit breaker yecala elibunjiwe kanye ne-air circuit breaker?

Ii-air circuit breakerixhunywe kusiyingi, inqamule futhi iphathe amaza amanje asebenzayo alinganiselwe kanye namaphutha avamile afana nephutha lesekethe emfishane nokuvikela ukulayisha ngokweqile.gcina.Ama-air circuit breaker ngokuvamile ane-voltage ephansi, okungukuthi, i-voltage evamile yokusebenza elinganiselwe ingu-1Kv nangaphansi.I-air circuit breaker iyisisetshenziswa sokushintsha amandla esinemisebenzi eminingi yokulungisa engasika futhi ixhumanise amasekhethi ngesikhathi esilinganiselwe samanje nesikaliwe sokusebenza.Uhlobo lomsebenzi wayo wokulungisa kanye nendlela yokuvikela kufanele kukhethwe ikhasimende.Okufana nokuvikeleka kwe-overcurrent, ukuvikelwa kwe-overcurrent, ukusebenza, ukungasebenzi kahle, njll. Izinhlobo ezimbili zokuqala zokulungisa ziwukucushwa okuyisisekelo kwe-air circuit breaker, kanti lezi ezimbili zokugcina ziyazikhethela.Ngakho-ke, ama-air circuit breaker angaphinda avule amasekhethi kagesi ezimweni ezivamile zephutha (ukulayisha iphutha le-short-circuit, i-overcurrent yokulayisha, i-voltage ephansi, njll.).Ii-plastic case circuit breaker ingakwazi ukunqamula i-curse ngokuzenzakalelayo, lapho ukulayishwa kwamanje okungaphezu kwamandla kanye nephutha lesifunda esifushane, inganqamula ngokuzenzakalelayo futhi inqamule ukunikezwa kwamandla.Isekhethi yekesi yepulasitiki isho i-casing yensimbi yezinto zokusebenza, esetshenziselwa ukuvikela indawo ephakathi ye-conductor kagesi kanye nedivayisi ephansi yezinto zensimbi.Izigebengu zamasekhethi epulasitiki ngokuvamile zinesistimu eshisayo, isistimu kazibuthe, kanye nemiphumela yesistimu eshisayo: uma i-current idlula umthamo wamanje odingekayo ngokwezinga likazwelonke, into eshisayo enegolide eliphindwe kabili izoshisa futhi yonakale, ibangele ukuguquguquka futhi ikhuthaze ukuma kwezicubu.Nqamula, ngomphumela wokuvikela i-overvoltage;Umthelela wesistimu kazibuthe: Lapho i-current idlula umthamo we-short-circuit edingwa yizinga likazwelonke, ikhoyili kagesi ohlelweni lukazibuthe izokhiqiza i-flux kazibuthe enkulu kakhulu, futhi lapho amandla abangelwa ukugeleza kazibuthe edlula ukuzulazula kwe-transformer core Amandla e-axial entwasahlobo, umgogodla oguquguqukayo we-transformer ohlelweni lukazibuthe uzothuthukisa isikhundla seketango elincane, iketango elincane lizokhuthaza indawo yokuvala izicubu, i-rocker izophuka, futhi ibone ukuvikeleka kwe-overcurrent.Ngobubanzi, ama-breaker circuit afaka phakathi: ama-breaker circuit, ama-circuit breaker abunjiwe, nama-breaker circuit amancane.Kunezimbobo ezintathu ku-switch yokuhlukanisa igobolondo lepulasitiki, exhunywe kugesi wezigaba ezintathu (empeleni i-380V), esetshenziselwa uhlelo lokusabalalisa amandla okukhiqizwa kwezimboni kanye nesofthiwe yesistimu yokuvikela imoto;umshini wokuhlukanisa osetshenziswa ezindlini ubhekisela esigabeni esisodwa (empeleni esingu-220V), esisetshenziselwa ukukhiqizwa kwezimboni zamasistimu okusabalalisa amandla kanye nesofthiwe yesistimu yokuvikela imoto.Ukugcinwa kwezinto zokusabalalisa amandla kagesi ezisetshenziswa zokugcina ubunjiniyela.Ngakho-ke, kunezimbobo ezintathu ku-switch yokuhlukanisa igobolondo lepulasitiki, engakwazi ukusetshenziselwa ukusetshenziswa ekhaya.
