Izinhlobo ze-Circuit Breaker kanye nomhlahlandlela wokusebenzisa

UkuqondaAma-circuit BreakerAmadivayisi Okuphepha Abalulekile Ezinhlelweni Zikagesi

Ezweni lobunjiniyela kagesi kanye nokuphepha kwasekhaya, igama elithi “circuit breaker” livela kakhulu. I-circuit breaker iyithuluzi elibalulekile elenzelwe ukuvikela amasekethe kagesi ekugcwaleni ngokweqile kanye namasekethe amafushane, okuqinisekisa ukuphepha kwezinhlelo zikagesi kanye nalabo abazisebenzisayo. Lesi sihloko sibheka ngokujulile umsebenzi, izinhlobo, kanye nokubaluleka kwamasekethe aphulayo ezinhlelweni zikagesi zanamuhla.

Kuyini i-circuit breaker?

I-circuit breaker iyiswishi ezenzakalelayo ephazamisa ukuhamba kukagesi kwisekethe uma ibona isimo esingajwayelekile, njengokugcwala ngokweqile noma i-short circuit. Ngokungafani nama-fuse, okumele ashintshwe ngemva kokuba evunguzile, ama-circuit breaker angasethwa kabusha ngemva kokuba ekhubekile, okwenza abe inketho yokuphepha kagesi elula nephumelelayo. Avame ukufakwa kumaphaneli kagesi futhi abalulekile ekuvimbeleni imililo kagesi kanye nomonakalo wemishini.

Ama-circuit breaker asebenza kanjani?

Ama-circuit breaker asebenza ngokusekelwe ezindleleni ezimbili eziyinhloko: ukushisa kanye ne-magnetic.

1. Indlela yokushisa: Le ndlela isebenzisa umucu we-bimetallic ofudumalayo futhi ugobe lapho ugesi uphezulu kakhulu. Lapho umucu we-bimetallic ugoba ngezinga elithile, ubangela ukuthi i-circuit breaker ivuleke, okuphazamisa i-circuit.

2. Indlela yokusebenza kagesi: Le ndlela yokusebenza incike emandleni kagesi. Uma kwenzeka i-short circuit, ukukhuphuka kwamandla kagesi okungazelelwe kudala insimu yamagnetic enamandla ngokwanele ukudonsa i-lever, ngaleyo ndlela kuphule i-circuit.

Amanye ama-circuit breaker anamuhla ahlanganisa zombili izindlela zokuvikela okuthuthukisiwe futhi aziwa ngokuthi ama-circuit breaker “anemisebenzi emibili”.

Izinhlobo zama-circuit breaker

Kunezinhlobo eziningana zama-circuit breaker, ngayinye inenjongo ethile:

1. Ama-Standard Circuit Breaker: Lawa ama-circuit breaker avame kakhulu ukutholakala ezakhiweni zokuhlala nezebhizinisi. Avikela ekugcwaleni ngokweqile kanye nama-short circuit.

2. I-Ground Fault Circuit Interrupter (GFCI): Lawa ma-circuit breaker aklanyelwe ukuvikela amaphutha omhlaba, okwenzeka lapho ukuvuza kwamandla kagesi kusuka ku-circuit yawo ehlosiwe. Ama-GFCI avame ukusetshenziswa ezindaweni ezimanzi njengezindlu zangasese namakhishi.

3. I-Arc Fault Circuit Interrupter (AFCI): Ama-AFCI aklanyelwe ukuthola amaphutha e-arc angabangela imililo kagesi. Awusizo kakhulu emakamelweni okuphumula nasemakamelweni okulala.

4. Ama-Miniature Circuit Breaker (ama-MCB): Lawa ma-circuit breaker asetshenziswa ezisetshenziswayo ze-voltage ephansi futhi aklanyelwe ukukhubeka ku-current ethile elinganisiwe.

5. Idivayisi Yamanje Esele (i-RCD): Njenge-GFCI, i-RCD ivimbela ukushaqeka kukagesi ngokuthola ukungalingani kwamanje.

Ukubaluleka Kwama-Circuit Breakers

Ukubaluleka kwama-circuit breaker akunakuphikiswa. Angumugqa wokuqala wokuzivikela ezingozini zikagesi. Ngokuvala ugesi ngokuzenzakalelayo ezimweni eziyingozi, ama-circuit breaker asiza ekuvimbeleni imililo kagesi, umonakalo wemishini, kanye nokulimala komuntu.

Ngaphezu kwalokho, ama-circuit breaker asiza ekuthuthukiseni ukusebenza kahle kwezinhlelo zikagesi. Aphatha ngokuphephile imithwalo kagesi, aqinisekise ukuthi ama-circuit asebenza ngaphakathi kwamandla awo aklanyelwe wona. Lokhu akugcini nje ngokwandisa isikhathi sokuphila kwemishini, kodwa futhi kunciphisa nokusetshenziswa kwamandla.

UMGOMO OPHANSI

Ekuphetheni, ama-circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi zesimanje. Abalulekile ekuphepheni kwamakhaya namabhizinisi ngoba avimbela ukugcwala ngokweqile, ama-short circuit, kanye namanye amaphutha kagesi. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kungenza abantu bakwazi ukwenza izinqumo ezinolwazi mayelana nezinhlelo zabo zikagesi, ekugcineni kuthuthukiswe ukuphepha nokusebenza kahle. Njengoba ubuchwepheshe buqhubeka nokukhula, ama-circuit breaker ngokungangabazeki azodlala indima ebalulekile esikhathini esizayo sokuphepha kukagesi.
