Ama-circuit breaker esigaba esisodwaziyizingxenye ezibalulekile ezinhlelweni zikagesi, zihlinzeka ngokuvikelwa kokusebenzisa ugesi ngokweqile kanye nokwe-short-circuit. Zenzelwe ukuphazamisa ukuhamba kukagesi lapho kutholakala iphutha, ukuvimbela umonakalo ohlelweni lukagesi nokuqinisekisa ukuphepha komsebenzisi. Kulesi sihloko, sizohlola imisebenzi, izinhlobo, kanye nokusetshenziswa kwama-single-phase circuit breakers.
Imisebenzi ye-single phase circuit breaker
Umsebenzi oyinhloko we-single-phase circuit breaker ukuvikela i-circuit ekugcwaleni ngokweqile kanye nama-short circuit. Lapho ugesi ogeleza nge-circuit udlula umthamo olinganiselwe wezintambo nemishini, i-circuit breaker iyakhubeka, iphazamise ukuhamba kukagesi. Lesi senzo sivimbela ukushisa ngokweqile kanye nengozi yomlilo engaba khona. Ngaphezu kwalokho, uma kwenzeka i-short circuit futhi ugesi ukhuphuka ngokuzumayo, i-circuit breaker izonqamula ugesi ngokushesha ukuvimbela umonakalo ohlelweni.
Izinhlobo zama-single phase circuit breakers
Kunezinhlobo eziningana zama-circuit breaker esigaba esisodwa, ngayinye eyenzelwe izinhlelo zokusebenza ezithile kanye nezimo zokusebenza. Izinhlobo ezivame kakhulu zifaka phakathi ama-circuit breaker asebenzisa i-thermal-magnetic,ama-residual current breakers (RCCB)futhiama-miniature circuit breaker (MCB).
- Ama-circuit breaker asebenzisa i-thermal-magnetic: Lawa ma-circuit breaker ahlanganisa izindlela ze-thermal kanye ne-magnetic ukuze ahlinzeke ngokuvikelwa kokudlula ngokweqile kanye ne-short-circuit. I-thermal element iyasabela ezimweni ze-overcurrent, kuyilapho i-magnetic element ibona ukwanda okungazelelwe kwe-current, okuqinisekisa ukuvikelwa okuphelele.
- I-Residual Current Circuit Breaker (RCCB): I-RCCB yenzelwe ukuvikela ekushaqekeni kukagesi kanye nemililo kagesi ebangelwa amaphutha omhlaba. Iqapha ibhalansi yamanje phakathi kwabaqhubi abaphilayo nabangathathi hlangothi futhi ikhube isekethe lapho kutholwa iphutha.
- I-Miniature Circuit Breaker (MCB): I-MCB iyithuluzi elincane elisetshenziselwa ukuvikela amasekethe ekuthwaleni ngokweqile kanye namasekethe amafushane. Avame ukusetshenziswa ezindaweni zokuhlala kanye nezentengiselwano ngenxa yokwakheka kwawo okonga isikhala kanye nokulula kokufakwa.
Ukusetshenziswa kwe-single phase circuit breaker
Ama-circuit breaker esigaba esisodwa asetshenziswa kabanzi ezinhlelweni nasezinhlelweni zikagesi ezahlukahlukene. Ezindaweni zokuhlala, afakwa kumaphaneli kagesi ukuvikela ukukhanya, amasokhethi kagesi, kanye nezinto zasendlini. Ezindaweni zezentengiselwano nezezimboni, ama-circuit breaker esigaba esisodwa asetshenziswa ukuvikela imishini, imishini kanye nokufakwa kukagesi.
Ngaphezu kwalokho, ama-circuit breaker esigaba esisodwa abalulekile ezinhlelweni zamandla avuselelekayo njengokufakwa kwamandla elanga. Avikela ama-inverter, abalawuli beshaja kanye nezinye izingxenye zezinhlelo zamandla elanga, okuqinisekisa ukusebenza okuthembekile nokuphephile.
Ngamafuphi, ama-circuit breaker esigaba esisodwa adlala indima ebalulekile ekuphepheni kukagesi nasekuvikelweni kohlelo. Lawa madivayisi asiza ekuvimbeleni izingozi zikagesi kanye nomonakalo wemishini ngokubona nokuphazamisa ngempumelelo amaphutha okusebenzisa ugesi ngokweqile kanye namaphutha okusebenza kwe-short-circuit. Ukuqonda imisebenzi, izinhlobo, kanye nokusetshenziswa kwama-circuit breaker esigaba esisodwa kubalulekile ekuqinisekiseni ukuthembeka nokuphepha kohlelo lwakho lukagesi.
