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 circuits, ngaleyo ndlela evikela izingozi 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 esingajwayelekile, njengokugcwala ngokweqile noma i-short circuit. Ngokungafani nama-fuse, adinga ukushintshwa ngemva kokuqhuma, ama-circuit breaker angasethwa kabusha ngemva kokukhubeka, okwenza kube ukukhetha okulula futhi okuphumelelayo kokuvikela isekethe.
Ama-circuit breaker asebenza kanjani?
Isimiso sokusebenza se-circuit breaker silula: siqapha ugesi ogeleza nge-circuit. Uma ugesi udlula umkhawulo onqunyiwe, i-circuit breaker iyakhubeka, inqamule ukunikezwa kwamandla. Lesi senzo sivimbela ukushisa ngokweqile kanye nemililo engaba khona ebangelwa ugesi owedlulele. Indlela yokusebenza ngemuva kwalokhu ihilela izingxenye ezizwela ukushisa noma ezizwela amandla kazibuthe.
1. Ama-thermal circuit breaker: Lawa madivayisi asebenzisa umucu we-bimetallic ogobayo uma ushiswa ugesi omningi, ekugcineni ubangele ukushintsha, uphule ugesi.
2. I-magnetic circuit breaker: Le circuit breaker isebenza ne-electromagnet. Uma ugesi udlula umkhawulo ophephile, i-electromagnet iyanikwa amandla, idonsa i-lever ukuvula i-circuit.
Amanye ama-circuit breaker esimanje ahlanganisa imisebenzi yokushisa kanye neyamagnetic ukuze ahlinzeke ngokuvikelwa okuthuthukisiwe kanye nokusabela.
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 zibona amaphutha omhlabathi futhi zivimbela ukushaqeka kukagesi.
3. I-Arc Fault Circuit Interrupter (AFCI): Yakhelwe ukuvimbela imililo kagesi ebangelwa amaphutha e-arc, ama-AFCI ayadingeka kakhulu emakhaya amasha.
4. Ama-Miniature Circuit Breaker (ama-MCB): Lawa asetshenziswa ezisetshenziswayo ze-voltage ephansi futhi alungele ukuvikela isekethe eyodwa.
5. Ama-Residual Current Circuit Breakers (RCCB): Lawa madivayisi athola ukungalingani kokugeleza kwamandla kagesi futhi abalulekile ekuvimbeleni ukushaqeka kukagesi.
Ukubaluleka Kwama-Circuit Breakers
Ukubaluleka kwama-circuit breaker akunakweqiswa. Abalulekile ku:
- Kuvimbela imililo kagesi: Ngokuphazamisa ukuhamba kukagesi ngesikhathi sokulayisha ngokweqile, ama-circuit breaker anciphisa kakhulu ingozi yemililo ebangelwa ukushisa ngokweqile kwezintambo zikagesi.
- VIKELA AMADIVAYISI AKHO: Ama-circuit breaker asiza ukuvikela imishini kagesi neye-elekthronikhi emonakalweni obangelwa ukwanda kwamandla noma amaphutha.
- Ukuphepha okuthuthukisiwe: Uma kwenzeka iphutha, i-circuit breaker inganqamula ngokushesha nangokuphumelelayo ukunikezwa kwamandla ukuze ivikele ukuphepha kwabantu nempahla.
- Ukuthobela Imithetho Kagesi: Amakhodi amaningi okwakha adinga ukufakwa kwama-circuit breaker ukuqinisekisa ukuthi amazinga okuphepha ayahlangatshezwa.
Umugqa Ophansi
Ngamafuphi, ama-circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi zesimanje, ahlinzeka ngokuvikelwa okuyisisekelo ekuthwaleni ngokweqile, ama-short circuit, kanye namaphutha kagesi. Ukuhleleka kwawo kabusha kuwenza abe ukukhetha okusebenzayo kokubili ukusetshenziswa kwezindlu kanye nezentengiselwano. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kungasiza abantu benze izinqumo zokuphepha kagesi ezihlakaniphile ekhaya nasemsebenzini. Njengoba ubuchwepheshe buthuthuka, ama-circuit breaker azoqhubeka nokukhula, athuthukise indima yawo njengamaqhawe angaziwa okuphepha kukagesi.
