Isihloko: Ukuqonda Ukubaluleka Kwe-Ama-Earth Leakage Circuit Breakers
ukwethula
Ezweni lanamuhla lapho ukuphepha kukagesi kubaluleke kakhulu,ama-residual current breakers (ama-RCCB)badlala indima ebalulekile ekuvikeleni ukuphepha kwempilo yabantu kanye nempahla. Nakuba abaningi bengase bangalazi leli gama,Ama-RCCBziyingxenye ebalulekile yanoma yiluphi uhlelo lukagesi. Lesi sihloko sihlose ukucacisa ukubaluleka kwama-residual current breakers, umsebenzi wawo kanye nezinzuzo zawo ekuvikeleni ukufakwa kukagesi.
Isigaba 1: Kuyinii-earth leaking circuit breaker?
I-residual current breaker, evame ukubizwa ngokuthi i-I-RCCB, iyithuluzi likagesi elenzelwe ukuvikela abantu kanye nezindawo zikagesi ekushaqekeni kukagesi kanye nezingozi zomlilo ezibangelwa ukuvuza kukagesi. Kalula nje, i-I-RCCBiqapha ugesi osesekethe bese iphazamisa ugesi uma ithola ukungalingani kogesi. Lokhu kungalingani kungabangelwa ugesi ovuzayo, amaphutha okushisa, noma ukuxhumana ngqo nabaqhubi abaphilayo.
Isigaba 2: Kwenzeka kanjaniumsebenzi we-earth leak circuit breaker?
Ama-circuit breaker avuzayo afakwe ama-transformer azwelayo alinganisa njalo ugesi ngokusebenzisa ama-conductor aphilayo nangathathi hlangothi. Noma nini lapho kunomehluko phakathi kogesi wokufaka kanye nogesi wokubuya, kubonisa ukuvuza noma iphutha.I-RCCBibona lokhu kungafani bese ikhubaza isekethe ngokushesha, inqamule amandla ukuze ivimbele umonakalo owengeziwe.
Isigaba sesithathu: izinzuzo zama-leaking circuit breakers
Ukufaka i-earth leakage circuit breaker kunezinzuzo eziningi ngokuphepha nokuvikelwa. Okokuqala, kunganciphisa kakhulu ingozi yokushaqeka kukagesi ngokuthola ukungalingani okuncane kakhulu kwesekethe nokuphazamisa ugesi ngesikhathi. Okwesibili,Ama-RCCBzibalulekile ekuvikeleni emlilweni obangelwa amaphutha kagesi, njengoba zisabela ngokushesha emifudlaneni kagesi engajwayelekile, zinciphisa amathuba okushisa ngokweqile kanye nokugoba.
Ngaphezu kwalokho, ama-circuit breaker avuzayo anganqamula ngokushesha ukunikezwa kwamandla uma kwenzeka ukuvuza noma ukwehluleka, okuhlinzeka ngokuvikeleka okwengeziwe kwemishini nezinto zikagesi. Ngokwenza kanjalo, imishini eyigugu ingavikelwa ngendlela yokuvimbela ekulimaleni okungenzeka, okuholela ekongeni izindleko kanye nokuphila isikhathi eside.
Isigaba 4: Izinhlobo zama-earth leakage circuit breakers
Kunezinhlobo ezimbili eziyinhloko ze-Ama-RCCB: Uhlobo lwe-AC kanye nohlobo lwe-A. Ama-RCCB ohlobo lwe-AC avame ukusetshenziswa ezindaweni zokuhlala ukuze ahlinzeke ngokuvikelwa emifudlaneni eshintshashintshayo ye-sinusoidal. Lawa ma-RCCB afaneleka kakhulu ekuvikeleni emithonjeni evamile yokuvuza njengokungaxhumani kahle kwezintambo, izintambo ezonakele, kanye nokwehluleka kwemishini.
Ngakolunye uhlangothi, ama-RCCB ohlobo A athuthuke kakhulu futhi ahlinzeka ngokuvikeleka okwengeziwe ngokufaka ugesi oshintshashintshayo kanye nogesi oqondile oshayayo (DC). Lawa ma-RCCB avame ukufakwa ezicelweni zobungcweti ezifana nezibhedlela, izindawo zezimboni kanye nalapho kusetshenziswa khona imishini kagesi ebucayi kakhulu. Ama-RCCB ohlobo A aqinisekisa ukuvikeleka okugcwele emaphutheni e-AC kanye ne-DC ngaphandle kwesikhala sokuyekethisa.
Isigaba 5: Ukubaluleka kokuvamileI-RCCBukuhlolwa nokugcinwa
Nakuba ama-residual current breakers ngokungangabazeki abalulekile ekuphepheni kukagesi, kubalulekile futhi ukuqonda ukubaluleka kokuhlolwa nokugcinwa njalo. Njenganoma iyiphi enye idivayisi kagesi,Ama-RCCBukuguga ngokuhamba kwesikhathi, kunciphisa ukusebenza kwazo noma ngisho nokwehluleka. Ngakho-ke, ukuhlolwa nokugcinwa njalo kumele kuhlelwe ukuqinisekisa ukuthiI-RCCBisebenza kahle kakhulu futhi ivimbela noma yiziphi izingozi zikagesi ezingaba khona.
Isigaba 6: Isiphetho
Ekuphetheni, ama-residual current breakers ayingxenye ebalulekile yezinhlelo zikagesi zesimanje, ahlinzeka ngokuvikelwa okubalulekile ekushaqekeni kukagesi kanye nezingozi zomlilo. I-RCCB ingabona ukungalingani kwamanje futhi iphazamise isekethe ngesikhathi, okungathuthukisa kakhulu ukuphepha kokusetshenziswa kukagesi futhi kuvikele impilo kanye nempahla. Ngokutshala imali kuma-RCCB asezingeni eliphezulu, ukukhetha uhlobo olufanele lohlelo ngalunye, nokwenza ukuhlolwa nokugcinwa njalo, sonke singakha indawo kagesi ephephile kithi kanye nezizukulwane ezizayo.
