I-Residual current breaker (RCCB): umqaphi wokuphepha kukagesi

Ama-Residual current breakers (ama-RCCB)bangamaqhawe angaziwa okuphepha kukagesi. Bangumugqa wokuqala wokuzivikela ezingozini zikagesi, bevikela abantu nempahla ezingozini ezihambisana nokwehluleka kukagesi. Kulesi sihloko sibheka ngokujulile lokhoAma-RCCBukuthi ziyini, ukuthi zisebenza kanjani nokuthi kungani zibalulekile kuzo zonke izinhlelo zikagesi.

Ake siqale siqonde izisekelo zeI-RCCBNgamagama alula, i-I-RCCBiyithuluzi likagesi elisetshenziselwa ukuthola nokuvimbela amaphutha asele kagesi ukuthi angenzeki. Lokhu kwehluleka kuvame ukubangelwa ukwehluleka kokufakwa kokushisa noma ukuvuza kukagesi futhi kungaba yingozi uma kungatholakali. I-RCCB iqapha isekethe futhi inganqamula ngokushesha ukunikezwa kukagesi uma kwenzeka ukwehluleka, okunciphisa ngempumelelo ingozi yezingozi zikagesi njengokushaqeka kukagesi nomlilo.

Isici esibalulekile seAma-RCCBukuzwela kwazo ku-residual current. Ingabona ngisho nokungalingani okuncane kakhulu phakathi kwe-live kanye ne-neutral currents egeleza ku-circuit. Lokhu kuzwela kubalulekile ekuvimbeleni izingozi, njengoba kuvumelaI-RCCBukukhubeka ngaphakathi kwama-millisecond ngaphambi kokuba ugesi ufinyelele amazinga ayingozi. Ngokwenza lokhu, ama-RCCB ahlinzeka ngezinga lokuvikela ama-circuit breaker avamile angakwazi ukulivikela.

I-RCCB ifinyelele lokhu ngobuchwepheshe obuthuthukisiwe. NgaphakathiI-RCCBKukhona i-magnetic core enezingqimba ezimbili ezihlukene: eyokuqala neyesibili. Ukujikijela okuyinhloko kuthwala umsinga wesekethe, kuyilapho ukujikijela kwesibili kuqapha ukungalingani phakathi kwemisinga ephilayo nengathathi hlangothi. Uma lokhu kungalingani kudlula umkhawulo onqunyiwe, i-RCCB iyaphazamisa futhi iphazamise amandla, iqinisekisa ukuphepha.

Ngaphezu kokuthola ugesi osele, ama-RCCB ahlinzeka nangokuvikeleka kwe-short-circuit kanye nokuvikela ukulayisha ngokweqile. Lokhu kuguquguquka kuwenza abe yingxenye ebalulekile yanoma yiluphi uhlelo lukagesi. Ngokuhlanganisa imisebenzi ye-I-RCCBnge-circuit breaker ejwayelekile, kungaqinisekiswa ukuvikelwa okuphelele emaphutheni ahlukahlukene kagesi.

Ama-RCCB avame ukufakwa ebhodini lokushintsha eliyinhloko noma ekuqaleni kwesekethe. Lokhu kubekwa okunesu kuqinisekisa ukuthi yonke isekethe ivikelwe, kufaka phakathi yonke imishini nezinto zikagesi ezingezansi komfula. Kubalulekile ukuqaphela ukuthi ukuze kuphephe kakhulu, ama-RCCB kumele ahlolwe futhi agcinwe njalo. Ukuhlolwa njalo kuqinisekisa ukuthi imishini ihlala isesimweni esihle futhi iyaqhubeka nokunikeza isivikelo esisebenzayo.

Kafushane,ama-residual current breakers (RCCB)zidlala indima ebalulekile ekuqinisekiseni ukuphepha kwempilo kanye nempahla kanye nokugwema izingozi zikagesi. Njengoba zinekhono lokubona nokuvimbela amaphutha asele kagesi, zinikeza izinga elingenakuqhathaniswa lokuvikelwa ekushaqekeni kukagesi kanye nomlilo. Ukuzwela kwazo kuhlangene nekhono lazo lokuvikela kuma-short circuits kanye nokulayisha ngokweqile kuzenza zibe yingxenye ebalulekile yanoma yikuphi ukufakwa kukagesi. Okubalulekile kumele kunikezwe ukufakwa kanye nokugcinwa njalo kwe-Ama-RCCBukuqinisekisa amazinga aphezulu okuphepha kagesi. Khumbula,I-RCCBungumnakekeli wethu othembekile uma kukhulunywa ngokuphepha kukagesi.
