UkuqondaAma-circuit BreakerAmadivayisi Okuphepha Abalulekile Ezinhlelweni Zikagesi

Igama elithi “i-circuit breaker” livamile ezweni lobunjiniyela kagesi kanye nokuphepha kwasekhaya. Ama-circuit breaker ayizingxenye ezibalulekile ezivikela ama-circuit kagesi ekugcwaleni ngokweqile kanye nama-short circuit, okuqinisekisa ukuphepha kwezinhlelo zikagesi kanye nalabo abazisebenzisayo. Lesi sihloko sizobheka kabanzi umsebenzi, izinhlobo, kanye nokubaluleka kwama-circuit breaker ezinhlelweni zikagesi zanamuhla.

Kuyini i-circuit breaker?

I-circuit breaker iyiswishi kagesi ezenzakalelayo enqamula 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 ukukhetha okulula futhi okuphumelelayo kokuvikela isekethe. Ama-circuit breaker abalulekile ekuvimbeleni imililo kagesi, umonakalo wemishini, kanye nezinye izingozi ezihlobene nokungasebenzi kahle kukagesi.

Indlela ama-circuit breaker asebenza ngayo

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

1. Indlela yokuvikela ukushisa: Le ndlela isebenzisa umucu we-bimetallic ogoba lapho ugesi uphezulu kakhulu. Uma ugesi udlula inani elinqunyiwe, umucu wensimbi ugoba ngokwanele ukuze uqalise i-circuit breaker, ngaleyo ndlela unqume ugesi.

2. Indlela esebenza ngemagnethi: Le ndlela isebenza ngamandla kagesi. Uma kwenzeka i-short circuit, ukungena kwamandla kagesi ngokuzumayo kudala insimu yamagnetic enamandla ngokwanele ukudonsa i-lever bese iwisa i-circuit breaker.

Amanye ama-circuit breaker anamuhla ahlanganisa zombili izindlela zokuvikela okuthuthukisiwe, ahlinzeka ngempendulo ethembekile kakhulu ezinkingeni ezahlukahlukene zikagesi.

Izinhlobo zama-circuit breaker

Kunezinhlobo eziningana zama-circuit breaker, ngayinye inenjongo ethile:

1. Ama-Miniature Circuit Breaker (MCB): Lawa ma-circuit breaker avame ukusetshenziswa ezakhiweni zokuhlala nezebhizinisi ukuvikela ekugcwaleni ngokweqile kanye nama-short circuits. Ancane futhi angaphatha amazinga aphansi kuya kwaphakathi wamandla kagesi.

2. I-Residual Current Breaker (RCCB): Lawa madivayisi avimbela ukushaqeka kukagesi ngokuthola ukungalingani kwamanje. Uma kutholakala iphutha, i-RCCB izokhubeka futhi inqamule ugesi.

3. Ama-Residual Current Circuit Breakers (ELCB): Njengama-Residual Current Circuit Breakers (RCCB), ama-ELCB avikela amaphutha omhlaba. Abaluleke kakhulu ezindaweni ezimanzi njengasezindlini zangasese nasekhishini.

4. Ama-Air Circuit Breaker (ACB): Ama-air circuit breaker asetshenziswa ezisetshenziswa ezimbonini ukusingatha amazinga aphezulu wamandla kagesi nokunikeza isivikelo ekucindezelweni ngokweqile, i-short circuit, kanye ne-ground fault.

5. Ama-Hydraulic Magnetic Circuit Breaker: Lawa avame ukusetshenziswa ezinhlelweni zikagesi ezinkulu futhi ahlinzeka ngesisombululo esiqinile sokuvikela emifudlaneni enamandla amakhulu.

Ukubaluleka Kwama-Circuit Breakers

Ukubaluleka kwama-circuit breaker akunakuphikiswana ngakho. Angumugqa wokuqala wokuzivikela ezingozini zikagesi, avikela impilo kanye nempahla. Ama-circuit breaker anqamula ngokuzenzakalelayo ukuhamba kukagesi ezimweni eziyingozi, esiza ekuvimbeleni imililo kagesi, umonakalo wemishini, kanye nokulimala komuntu.

Ngaphezu kwalokho, ama-circuit breaker asiza ekuthuthukiseni ukusebenza kahle kwezinhlelo zikagesi. Ngokuvimbela ukugcwala ngokweqile, ama-circuit breaker aqinisekisa ukuthi imishini kagesi isebenza ngaphakathi kwemingcele ephephile, ngaleyo ndlela yandisa isikhathi sayo sokusebenza futhi inciphise izindleko zokulungisa.

Ngokufigqiwe

Sekukonke, ama-circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi zesimanje. Ikhono lawo lokubona nokuphendula amaphutha kagesi libalulekile ekuphepheni nasekusebenzeni kahle. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kungasiza abanikazi bezindlu namabhizinisi ukuthi benze izinqumo ezinolwazi mayelana nezinhlelo zabo zikagesi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ama-circuit breaker ngokungangabazeki azoqhubeka nokukhula, athuthukise indima yawo ekuvikeleni ingqalasizinda yethu kagesi.
