Izinhlobo Zokuphula Isifunda kanye Nomhlahlandlela Wokukhetha

Ama-circuit breaker ayizingxenye ezibalulekile ezinhlelweni zikagesi, asebenza njengezinto zokuvikela ukuvimbela umonakalo obangelwa ukugcwala ngokweqile kanye nama-short circuits. Ama-circuit breaker aklanyelwe ukuphazamisa ngokuzenzakalelayo ukuhamba kukagesi lapho kutholakala iphutha, okuqinisekisa ukuphepha kohlelo lukagesi kanye nabasebenzisi balo. Lesi sihloko sizogxila emisebenzini, ezinhlotsheni, kanye nokubaluleka kwama-circuit breaker ezisetshenziswa zikagesi zanamuhla.

Umsebenzi oyinhloko we-circuit breaker ukuvula nokuvala i-electrical circuit. Ngokungafani nama-fuse endabuko, okumele ashintshwe ngemva kokuba evunguzile, ama-circuit breaker angasethwa kabusha ngemva kokukhubeka, okwenza abe yisisombululo sokuvikela ugesi esilula nesisebenza kahle. Uma kwenzeka iphutha likagesi, njengokugcwala ngokweqile (ugesi odlula umthamo olinganiselwe we-circuit) noma i-short circuit (ugesi ogeleza ngendlela engahlosiwe), i-circuit breaker ithola i-anomaly futhi iphazamise ukuhamba kogesi, ivimbele izingozi ezingaba khona njengemililo kagesi noma umonakalo wemishini.

Kunezinhlobo eziningi ezahlukene zama-circuit breaker, ngayinye eyenzelwe izinhlelo zokusebenza ezithile kanye nezindawo ezithile. Izinhlobo ezivame kakhulu zifaka:

1. I-Miniature Circuit Breaker (MCB): Isetshenziswa ezindaweni zokuhlala nezentengiselwano ukuvikela ekugcwaleni ngokweqile kanye nama-short circuits. Ama-MCB aqinile futhi kulula ukuwafaka emabhokisini okusabalalisa.
2. I-Residual Current Breaker (RCCB): Eyaziwa nangokuthi idivayisi yamanje eseleyo (i-RCD), lesi siphuli sesekethe senzelwe ukuvimbela ukushaqeka kukagesi ngokuthola ukungalingani kwamanje. Uma othile ethinta intambo ephilayo, i-RCCB iyakhubeka, inqamule ukunikezwa kwamandla.
3. I-Earth leakage circuit breaker (ELCB): Njenge-RCCB, i-ELCB isetshenziselwa ukuthola amaphutha omhlaba nokuvimbela ukushaqeka kukagesi. Ama-ELCB abaluleke kakhulu ezindaweni ezimanzi njengasezindlini zangasese nangaphandle.
4. I-Air Circuit Breaker (i-ACB): Lolu hlobo lwe-circuit breaker lusetshenziswa ezinhlotsheni zezimboni futhi lungaphatha amazinga aphezulu kagesi. Ama-air circuit breaker asetshenziselwa ukuvikela izinhlelo ezinkulu zikagesi futhi angasetshenziswa ngesandla noma ngokuzenzakalelayo.
5. Ama-Hydraulic Magnetic Circuit Breakers: Lawa ma-circuit breaker asebenzisa inhlanganisela yezindlela zokushisa kanye nezama-magnetic ukuvula i-circuit. Ngokuvamile asetshenziswa ezinhlelweni zikagesi ezinkulu ezidinga ukuvikelwa kokusebenzisa ngokweqile kanye ne-short-circuit.

Ukubaluleka kwama-circuit breaker akunakuphikiswa. Adlala indima ebalulekile ekuqinisekiseni ukuphepha kwemishini kagesi nokuvikela abantu nempahla ezingozini zamaphutha kagesi. Ngaphandle kokuphepha, ama-circuit breaker nawo anegalelo ekuthuthukiseni ukuthembeka kohlelo lukagesi. Ngokuvimbela umonakalo wemishini nokunciphisa isikhathi sokungasebenzi, asiza ekugcineni ukusebenza kahle ezindaweni zokuhlala nezebhizinisi.

Ngaphezu kwalokho, intuthuko kwezobuchwepheshe iholele ekuthuthukisweni kwama-smart circuit breaker, anikeza amakhono athuthukisiwe njengokuqapha kude. Lawa madivayisi esimanje anganikeza idatha yokusetshenziswa kukagesi ngesikhathi sangempela, okwenza abasebenzisi bakwazi ukwenza ngcono ukusetshenziswa kwamandla futhi babone izinkinga ngaphambi kokuba ziqhubeke.

Kalula nje, ama-circuit breaker ayizinto zokuphepha ezibalulekile ezivikela izinhlelo zikagesi ekugcwaleni ngokweqile kanye nasezifundeni ezimfushane.Kunezinhlobo eziningi zama-circuit breaker, afanele ukusetshenziswa okuhlukahlukene, okuqinisekisa ukuphepha nokuthembeka kokufakwa kukagesi. Ngokuqhubeka kwentuthuko kwezobuchwepheshe, ikusasa lama-circuit breaker libukeka liqhakazile, njengoba izinto ezintsha zizothuthukisa ukusebenza kwazo kanye nokusebenza kahle ekuvikeleni ingqalasizinda kagesi. Ukuqonda indima nokubaluleka kwama-circuit breaker kubalulekile kunoma ubani osebenza nezinhlelo zikagesi, kungaba uchwepheshe noma umninikhaya ofuna ukuqinisekisa ukuphepha kwazo.

 

Iyini i-circuit breaker?
I-circuit breaker iyithuluzi lokuphepha likagesi elenzelwe ukuvikela isekethe kagesi emonakalweni obangelwa ugesi ongaphezu kwalokho umshini ongakuthwala ngokuphephile (ugesi ongaphezu kwamandla). Umsebenzi walo oyisisekelo ukuphazamisa ukuhamba kogesi ukuvikela imishini nokuvimbela umlilo.
