Ukuhlaziywa Kwemisebenzi Nokusetshenziswa Kwama-RCD Circuit Breakers

Ukuqonda Ama-Residual Current Operated Circuit Breakers: Umhlahlandlela Ophelele

Emkhakheni wokuphepha kukagesi, amadivayisi wamanje asele asetshenziswa njenge-circuit breaker (ama-RCD) adlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi. Lesi sihloko sigxila emisebenzini, ukubaluleka, kanye nokusetshenziswa kwama-RCD ohlobo lwe-circuit breaker, okuhloswe ukusiza abafundi ukuthi baqonde kabanzi ngale divayisi ebalulekile.

Iyini i-residual current circuit breaker (RCD)?

I-residual current current breaker (RCD) iyithuluzi lokuphepha elenzelwe ukuvimbela ukushaqeka kukagesi kanye nemililo kagesi ebangelwa amaphutha okubeka phansi. Isebenza ngokuqapha ugesi osesekethe. Uma ithola ukungalingani kugesi phakathi kwentambo ephilayo (isigaba) kanye nentambo engathathi hlangothi, okubonisa ukuvuza kwamanje entanjeni yomhlabathi, i-RCD inqamula ugesi ngokushesha. Lokhu kusabela okusheshayo—ngokuvamile ngaphakathiAma-millisecond angu-30— kuvimbela izehlakalo ezincane ukuthi zingabi izingozi ezisongela ukuphila.

Uyini umehluko phakathi kwe-standard breaker kanye ne-RCD breaker?

Umehluko oyinhloko phakathi kwe-RCD ne-circuit breaker usenjongweni yazo: I-RCD: Ivikela abantu ekushaqekeni kukagesi noma ekushayweni ugesi ngokuthola ugesi ovuzayo. I-Circle Breaker: Ivikela izinhlelo zikagesi kanye nezinto zikagesi ngokusika ugesi ngesikhathi sogesi odlulayo noma omfushane.

Iyini isimiso sokusebenza sedivayisi yamanje eseleyo (i-RCD) ku-circuit breaker?

Isimiso sokusebenza se-residual current current breaker (RCD) sisekelwe kusimiso samanje esihlukile. Ngaphansi kwezimo ezivamile, ugesi ogeleza ngentambo ephilayo kufanele ulingane nogesi ogeleza ngentambo engathathi hlangothi. Kodwa-ke, uma kwenzeka iphutha, njengokushaqeka kukagesi noma umonakalo kagesi, ugesi othile ungavuza uye entanjeni yomhlabathi. I-RCD ibona lokhu kungalingani kwamanje bese ikhubeka ukuze inqamule isekethe, ngaleyo ndlela inqamule ukunikezwa kwamandla.

Amadivayisi wamanje asele (ama-RCD) afika ngezilinganiso ezahlukene, ngokuvamile kusukela ku-30 mA yokuzivikela komuntu siqu to 100 mA noma 300 mA yokuvikela umliloIzilinganiso eziphansi zisho ukuthi idivayisi isheshe izwele kakhulu ekuvuthweni kwamanzi, okwenza ama-RCD abaluleke kakhulu ezindaweni lapho ukuphepha komuntu siqu kuyindaba eyinhloko.

Ukubaluleka Kwama-Residual Current Breakers

Ukubaluleka kwamadivayisi asebenza ngogesi asele (RCD) kuma-circuit breaker akunakunganakwa. Abalulekile ekuvimbeleni izingozi zikagesi ezingaholela ekulimaleni okukhulu komuntu noma ngisho nasekufeni. Izibalo zibonisa ukuthi ama-RCD angakwazikunciphisa ingozi yokushaqeka ngogesi ngamaphesenti afinyelela ku-90%.Lokhu kubenza babe yingxenye ebalulekile yezinhlelo zikagesi zokuhlala, zezentengiselwano, nezezimboni.

Ngaphezu kokuqinisekisa ukuphepha komuntu siqu, amadivayisi kagesi asele (ama-RCD) nawo avikela ukufakwa kukagesi ekulimaleni. Amaphutha kagesi angaholela ekushiseni ngokweqile nasemoyeni, okubangela umonakalo omkhulu wempahla. Ama-RCD asiza ekunciphiseni lezi zingozi ngokunqamula isekethe uma kwenzeka iphutha, ngaleyo ndlela andise isikhathi sokuphila kwezinhlelo zikagesi nemishini.

Ukusetshenziswa Kwamadivayisi Okuvikela I-Residual Current Breaker Protection Devices

Amadivayisi asele kagesi (ama-RCD) asetshenziswa kabanzi ezindaweni ezahlukene. Ezakhiweni zokuhlala, avame ukufakwa emabhokisini okusabalalisa ukuvikela amasekethe ahlinzeka ngogesi ezindaweni zokukhipha ugesi, ukukhanyisa, kanye nemishini yangaphandle. Ezakhiweni zezentengiselwano, ama-RCD abalulekile ekuvikeleni abasebenzi namakhasimende, ikakhulukazi ezindaweni ezinamanzi, njengekhishi nezindlu zangasese.

Ezindaweni zezimboni, amadivayisi okuvikela asetshenziswa njengamanje asele (ama-RCD) abalulekile ekuvikeleni imishini nokuqinisekisa ukuphepha kwabasebenzi abangase babhekane nezingozi zikagesi. Ngaphezu kwalokho, amakhodi nemithetho kagesi ngokuvamile idinga ukufakwa kwama-RCD, okwenza abe yingxenye ejwayelekile yokufakwa kukagesi kwesimanje.

Kafushane

Ngamafuphi, amadivayisi amanje asele asebenzisa i-circuit breaker (ama-RCD) ayimishini ebalulekile emkhakheni wokuphepha kukagesi. Angabona futhi aphendule ngokushesha emaphutheni kagesi, okwenza abe yingxenye ebalulekile ekuvikeleni impilo nempahla. Kungakhathaliseki ukuthi kusemakhaya, emabhizinisini, noma ezindaweni zezimboni, ukufaka ama-RCD ohlobo lwe-circuit breaker kuyisinyathelo esisebenzayo esingathuthukisa ukuphepha futhi sinciphise ingozi yezingozi zikagesi. Ngokuthuthuka kwezobuchwepheshe, ukwakheka nokusebenza kwama-RCD kuhlale kuthuthukiswa, kuqinisekisa ukuthi ahlala ehamba phambili ezixazululweni zokuphepha kukagesi.
