Ama-Circuit Breakers: Abaqaphi Bokuphepha Kwamandla

UkuqondaAma-circuit BreakerAmadivayisi Okuphepha Abalulekile Ezinhlelweni Zikagesi

Ezweni lobunjiniyela kagesi kanye nokuphepha kwasekhaya, igama elithi “circuit breaker” livame ukuvela. I-circuit breaker iyithuluzi elibalulekile elenzelwe ukuvikela amasekethe kagesi emonakalweni obangelwa ukugcwala ngokweqile noma amasekethe amafushane. Ngokuphazamisa ngokuzenzakalelayo ukuhamba kukagesi lapho kutholakala iphutha, amasekethe adlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kwezinhlelo zikagesi ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni.

Kuyini i-circuit breaker?

I-circuit breaker empeleni iyiswishi ye-electromechanical evula noma ivala isekethe ngaphansi kwezimo ezijwayelekile nezingalungile. Ngokungafani ne-fuse, okumele ishintshwe ngemva kokuba ishayile, i-circuit breaker ingasethwa kabusha ngemva kokuba ishayile, okwenza kube ukukhetha okulula nokuqhubekayo kokuvikela isekethe. Ziza ngezinhlobo ezahlukene nosayizi ukuze zihlangabezane nezidingo ezithile zezinhlelo zokusebenza ezahlukene.

Izinhlobo zama-circuit breaker

Kunezinhlobo eziningana zama-circuit breaker, ngayinye inomsebenzi wayo othize:

1. I-Miniature Circuit Breaker (MCB): Lawa ma-circuit breaker avame ukusetshenziswa ezindaweni zokuhlala nezentengiselwano ukuvikela ekugcwaleni ngokweqile kanye nama-short circuits. Ama-MCB aklanyelwe ukukhubeka ngokuzenzakalelayo lapho ugesi udlula izinga elinqunyiwe.

2. Ama-Residual Current Circuit Breakers (RCCB): Lawa ma-circuit breaker, aziwa nangokuthi ama-RCD (Residual Current Devices), aklanyelwe ukuvimbela ukushaqeka kukagesi ngokuthola ukungalingani kwamandla kagesi. Uma kwenzeka iphutha, njengomuntu othinta ucingo oluphilayo, i-RCCB izokhubeka, inqume ukunikezwa kwamandla kagesi.

3. I-Leakage Current Circuit Breaker (ELCB): Njenge-RCCB, i-ELCB isetshenziselwa ukuthola amaphutha omhlaba nokuvimbela ukushaqeka kukagesi. Zibaluleke kakhulu ezindaweni ezimanzi, njengezindlu zangasese namakhishi.

4. Ama-Air Circuit Breaker (ACB): Lawa ma-circuit breaker asetshenziswa ezinhlotsheni ze-voltage ephezulu futhi angaphatha ama-current aphezulu. Ama-ACB avame ukusetshenziswa ezindaweni zezimboni futhi aklanyelwe ukuvikela izinhlelo ezinkulu zikagesi.

5. Ama-Hydraulic Magnetic Circuit Breaker: Lawa ma-circuit breaker asebenzisa inhlanganisela yezindlela ze-hydraulic kanye ne-electromagnetic ukusika i-circuit. Avame ukusetshenziswa ezinhlelweni zikagesi ezinkulu ezidinga ukulawulwa okunembile.

Indlela ama-circuit breaker asebenza ngayo

Ama-circuit breaker asebenza ngokuthola i-overcurrent. Uma i-current egeleza nge-circuit idlula umthamo olinganiselwe we-circuit breaker, ibangela indlela evula i-circuit, ngaleyo ndlela ivimbele ukugeleza kwe-current. Lokhu kungenzeka ngezizathu eziningana, njenge-short circuit, i-overloaded circuit, noma iphutha ohlelweni lukagesi.

Indlela yohambo ingaba ukushisa, amandla kazibuthe, noma inhlanganisela yakho kokubili. Uhambo lokushisa lusebenzisa umucu we-bimetallic ogobayo uma ushiswa amandla kagesi amaningi, kuyilapho uhambo olusebenzisa amandla kazibuthe lusebenzisa i-electromagnet esebenza lapho amandla kagesi edlula umkhawulo othile.

Ukubaluleka Kwama-Circuit Breakers

Ukubaluleka kwama-circuit breaker akunakuphikiswana ngakho. Abalulekile ekuvimbeleni imililo kagesi, ekuvikeleni izinto zikagesi kanye nemishini ekulimaleni, nasekuqinisekiseni ukuphepha komuntu siqu. Ekhaya, ama-circuit breaker ayindlela yokuqala yokuzivikela ezingozini zikagesi, okuvumela abanikazi bezindlu ukuthi basheshe bayisethe kabusha uhlelo ngemva kohambo.

Ngaphezu kwalokho, ama-circuit breaker asiza ekuthuthukiseni ukusebenza kahle kwezinhlelo zikagesi. Ngokuvimbela ukugcwala ngokweqile, ama-circuit breaker asiza ekugcineni ubuqotho bengqalasizinda kagesi, anciphise ingozi yokulungiswa okubizayo kanye nesikhathi sokungasebenzi.

UMGOMO OPHANSI

Ekuphetheni, ama-circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi zesimanje. Abalulekile ekuphepheni kwamakhaya, amabhizinisi, kanye nezindawo zezimboni ngoba avimbela ukugcwala ngokweqile kanye nama-short circuit. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kungasiza abantu ngabanye ukuba benze izinqumo ezinolwazi mayelana nokuphepha kukagesi kanye nokugcinwa kwawo. Njengoba ubuchwepheshe buqhubeka nokukhula, ama-circuit breaker ngokungangabazeki azodlala indima ebalulekile esikhathini esizayo sobunjiniyela kagesi kanye nokuphepha.
