UkuqondaAma-circuit Breaker: Amaqhawe Angadumile Okuphepha Kukagesi
Ama-circuit breaker adlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kwezinhlelo zikagesi. Lawa madivayisi aklanyelwe ukuvikela ama-circuit kagesi ekugcwaleni ngokweqile kanye nama-short circuit njengesivikelo ezingozini ezingaba khona. Ukuqonda ukuthi ama-circuit breaker asebenza kanjani, izinhlobo zawo, kanye nokubaluleka kwawo kungasiza abanikazi bezindlu nochwepheshe ukugcina indawo kagesi ephephile.
Kuyini i-circuit breaker?
I-circuit breaker iyiswishi kagesi ezenzakalelayo ephazamisa ukuhamba kukagesi kwisekethe uma ibona isimo esingavamile, njengokugcwala ngokweqile noma i-short circuit. Ngokungafani nama-fuse, okumele ashintshwe ngemva kokuba ephephukile, ama-circuit breaker angasethwa kabusha ngemva kokuba ekhubekile, okwenza kube ukukhetha okulula futhi okuphumelelayo kokuvikela isekethe.
Ama-circuit breaker asebenza kanjani?
Isimiso sokusebenza sama-circuit breaker silula: aqapha ugesi ogeleza ngesekethe. Uma ugesi udlula umkhawulo onqunyiwe, i-circuit breaker iyakhubeka, inqamule ugesi. Lesi senzo sivimbela ukushisa ngokweqile kanye nemililo engaba khona ebangelwa ugesi odlulele. Indlela yokusebenza ivame ukuhilela ugesi ohamba ngokushisa noma uhlelo lokuhamba olunezinjini.
- Ama-circuit breaker ashisayo: Lawa ma-circuit breaker asebenzisa umucu we-bimetallic ogobayo uma ushiswa ugesi omningi, ekugcineni ubangele iswishi yokuvula i-circuit.
- Ama-circuit breaker e-electromagnetic: Lawa ma-circuit breaker aphatha ukukhuphuka kwamanje okungazelelwe, njengalokho okubangelwa yi-short circuit. Asebenzisa i-electromagnet ukudonsa i-lever, ephula i-circuit cishe ngokushesha.
Izinhlobo zama-circuit breaker
Kunezinhlobo eziningana zama-circuit breaker, ngayinye inenjongo ethile:
1. I-circuit breaker ejwayelekile: Ivame ukutholakala ezindaweni zokuhlala, isetshenziselwa ukuvikela ekucindezelweni ngokweqile kanye ne-short circuits.
2. Iziphazamisi Zesifunda Sephutha Lomhlabathi (GFCI): Zibalulekile ezindaweni ezimanzi njengezindlu zangasese namakhishi njengoba zingakwazi ukubona amaphutha omhlaba futhi zivimbele ukushaqeka kukagesi.
3. Ama-Arc Fault Circuit Interrupters (AFCI): Aklanyelwe ukuvimbela imililo kagesi ebangelwa amaphutha e-arc, lawa ma-circuit breaker aya ngokuya ethandwa kakhulu emakhaya anamuhla.
4. I-Miniature Circuit Breaker (MCB): Isetshenziswa ezisetshenziswayo ze-voltage ephansi futhi inikeza ukuvikelwa kokusetshenziswa ngokweqile.
5. I-Residual Current Breaker (RCCB): Ithola ukungalingani kwamandla kagesi futhi ibalulekile ekuvimbeleni ukushaqeka kukagesi.
Ukubaluleka Kwama-Circuit Breakers
Ukubaluleka kwama-circuit breaker akunakweqiswa. Abalulekile ku:
- Ukuphepha: Ama-circuit breaker avikela impilo kanye nempahla ngokuvimbela imililo kagesi kanye nokushaqeka kukagesi.
- KULULA: Ngokungafani nama-fuse adinga ukushintshwa, ama-circuit breaker angasethwa kabusha kalula, okunciphisa isikhathi sokungasebenzi.
- Izindleko eziphansi: Nakuba ukutshalwa kwezimali kokuqala kungaba phezulu kune-fuse, ama-circuit breaker onga imali ngokuhamba kwesikhathi ngoba anciphisa ingozi yomonakalo kagesi kanye nesidingo sokushintshwa njalo.
- Ukuthobela imithetho: Amakhodi amaningi okwakha adinga ukufakwa kwama-circuit breaker, ikakhulukazi i-GFCI ne-AFCI, ukuqinisekisa ukuthi amazinga okuphepha ayahlangatshezwa.
Umugqa Ophansi
Ngamafuphi, ama-circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi zesimanje, ahlinzeka ngokuvikelwa okuyisisekelo ekuthwaleni ngokweqile kanye nama-short circuits. Angasethwa kabusha ngemva kokukhubeka, okwenza kube ukukhetha okusebenzayo kokubili ukusetshenziswa kwezindawo zokuhlala kanye nezentengiselwano. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kuvumela abantu ngabanye ukuthi benze izinqumo ezinolwazi mayelana nokuphepha kukagesi emakhaya abo nasezindaweni zokusebenza. Njengoba ubuchwepheshe buthuthuka, ama-circuit breaker azoqhubeka nokukhula, athuthukise indima yawo njengamaqhawe angaziwa okuphepha kukagesi.
