Ukuhlaziywa Kokusebenza kwe-Residual Current Circuit Breaker RCBO

UkuqondaAma-RCBO Residual Current Breakers: Umhlahlandlela Ophelele

Emkhakheni wokuphepha kukagesi,Ama-RCBO (ama-residual current breakers ane-overcurrent protection)ziyizingxenye ezibalulekile emishini kagesi yesimanje. Zihlanganisa ukusebenza kwamadivayisi wamanje asele (ama-RCD) kanye nama-miniature circuit breaker (ama-MCB), zihlinzeka ngokuvikelwa okubili emaphutheni omhlaba kanye nezimo zomsinga odlulele. Lesi sihloko sizogxila ezimisweni zokusebenza, izinzuzo, kanye nokusetshenziswa kwama-RCBO.

Kuyini i-RCBO?

Ama-RCBO aklanyelwe ukuvikela amasekethe kagesi ezingozini ezimbili eziyinhloko: amaphutha omhlaba kanye nokulayisha ngokweqile. Iphutha lomhlaba lenzeka lapho ugesi ugeleza uye emhlabathini ngendlela engahlosiwe, okungase kubangele ukushaqeka kukagesi noma umlilo. Ngakolunye uhlangothi, ukugcwala ngokweqile kwenzeka lapho ugesi ogeleza ngesekethe udlula umthamo wawo olinganiselwe, okungase kubangele ukushisa ngokweqile futhi kulimaze izinto zikagesi.

I-RCBO iqapha njalo ugesi ogeleza ngesekethe. Uma ibona ukungalingani phakathi kwabaqhubi abashisayo nabangathathi hlangothi (okungukuthi, ugesi ovuzayo), iyakhubeka futhi inqamule isekethe. Iphinde ikhubeke uma ugesi udlula umkhawulo onqunyiwe, ivikele isekethe kuzo zombili izinhlobo zamaphutha.

Izici eziyinhloko ze-RCBO

1. Ukuvikelwa Okubili: Inzuzo eyinhloko ye-RCBO yikhono layo lokuhlinzeka kokubili ukuvikelwa kwamanje okusele kanye nokuvikelwa kwamanje okweqile kudivayisi eyodwa. Lokhu kuqeda isidingo sama-RCD nama-MCB ahlukene, ngaleyo ndlela kube lula uhlelo lukagesi.

2. Umklamo Omncane: Ama-RCBO ngokuvamile ancane kakhulu kunokusebenzisa amadivayisi ahlukene, okuvumela ukusetshenziswa kahle kwesikhala kumayunithi abathengi noma amabhodi okusabalalisa.

3. Ukukhetha Okuhlukile: Ama-RCBO amaningi aklanywe ngendlela yokukhetha ukukhubeka, okusho ukuthi uma kwenzeka iphutha, isekethe ethintekile kuphela ezonqanyulwa. Lesi sici sithuthukisa ukuthembeka kohlelo lukagesi futhi sinciphisa ukuphazamiseka kwezinye isekethe.

4. Ukuzwela OkulungisekayoAma-RCBO anikeza amazinga ahlukahlukene okuzwela, ngokuvamile asukela ku-30mA yokuvikela komuntu siqu kuya ku-100mA noma ku-300mA yokuvikela imishini. Lokhu kuguquguquka kuvumela uhlelo lokuvikela ukuthi lwenziwe ngokwezifiso ngokwezidingo ezithile zokufakwa.

Ukusetshenziswa kwe-RCBO

Ama-RCBO asetshenziswa kabanzi ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni. Emakhaya, avame ukufakwa ezintweni zikagesi ukuvikela amasekethe anika amandla izinto ezibalulekile njengeziqandisi, imishini yokuwasha, kanye nezinhlelo zokushisa. Ezakhiweni zezentengiselwano, ama-RCBO abalulekile ekuvikeleni imishini ebucayi kanye nokuqinisekisa ukuphepha kwabasebenzi namakhasimende.

Ezisetshenziswa ezimbonini, ama-RCBO asetshenziswa emishinini edinga ukuvikelwa kwephutha lomhlabathi kanye nokusetshenziswa ngokweqile. Ukuvikelwa kwawo okuthembekile kusiza ekugwemeni ukungasebenzi okubizayo kanye nomonakalo wemishini.

Ngokufigqiwe

Amadivayisi wamanje asele e-RCBO (ama-RCBO) abalulekile ekuqinisekiseni ukuphepha kukagesi kuzo zonke izindawo. Ahlanganisa ukusebenza kwama-RCD nama-MCB, ahlinzeka ngokuvikelwa okuphelele kwephutha lomhlaba kanye nokweqisa komsinga. Ngokuvikelwa okubili, ukwakheka okuhlangene, ukukhubeka okukhethiwe, kanye nokuzwela okulungisekayo, ama-RCBO ayisisombululo esiguquguqukayo sokufakwa kukagesi kwesimanje. Njengoba ukuphepha kohlelo lukagesi kuyinto eza kuqala, ukuqonda nokusebenzisa ama-RCBO kubalulekile ekuvikeleni impilo kanye nempahla. Kungakhathaliseki ukuthi kusezindaweni zokuhlala, zezentengiselwano, noma zezimboni, ama-RCBO ayisihluthulelo sokuphepha kukagesi.
