I-Residual current breaker (RCCB): umlindi wokhuseleko lombane

I-Residual current breaker (RCCB): umgcini wokhuseleko lombane

Iziphuli zesekethe ezisele (ii-RCCB)ngamagorha angadunyiswanga okhuseleko lombane. Ngawo angundoqo wokuzikhusela kwiingozi zombane, ekhusela abantu kunye nempahla kwiingozi ezinxulumene nokusilela kombane. Kweli nqaku siza kujonga nzulu kwintoIi-RCCBzinjani, indlela ezisebenza ngayo kunye nesizathu sokuba zibalulekile kuyo yonke into efakelwa umbane.

Masiqale siqonde iziseko zeI-RCCBNgamazwi alula, iI-RCCBsisixhobo sombane esisetyenziselwa ukubona nokuthintela iimpazamo zamandla aseleyo ukuba zenzeke. Ezi mpazamo zihlala zibangelwa kukungasebenzi kakuhle kwe-insulation okanye ukuvuza kombane kwaye zinokubulala ukuba azibonwanga. I-RCCB ijonga isekethe kwaye ingawucima ngokukhawuleza umbane xa ungasebenzi, nto leyo enciphisa ngempumelelo umngcipheko weengozi zombane ezifana nokutshayiswa kombane kunye nomlilo.

Uphawu oluphambili lweIi-RCCBbubuthathaka babo kumbane oseleyo. Ingabona nokungalingani okuncinci phakathi kombane ophilayo nongakhethiyo ohamba kwisekethe. Olu buthathaka lubalulekile ekuthinteleni iingozi, njengoko luvumelaI-RCCBukukhubeka kwii-milliseconds ngaphambi kokuba umsinga ufikelele kumanqanaba ayingozi. Ngokwenza oku, ii-RCCB zibonelela ngenqanaba lokhuseleko olungenakwenziwa zi-circuit breakers eziqhelekileyo.

I-RCCB ifezekise oku ngetekhnoloji ephucukileyo.I-RCCBKukho isiseko semagnethi esinee-windings ezimbini ezahlukeneyo: eyokuqala neyesibini. I-winding yokuqala ithwala umsinga wesekethe, ngelixa i-winding yesibini ijonga ukungalingani phakathi kwe-live kunye ne-neutral currents. Ukuba oku kungalingani kudlula umda obekiweyo, i-RCCB iyawa kwaye iphazamise amandla, iqinisekisa ukhuseleko.

Ukongeza ekufumaneni umsinga osele, ii-RCCB zikwabonelela ngokhuseleko lwe-short-circuit kunye nokukhusela ukugqithisa. Olu tshintsho lubenza babe yinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane. Ngokudibanisa imisebenzi ye-I-RCCBngesixhobo esiqhelekileyo sokwaphula iisekethe, ukhuseleko olupheleleyo kwiimpazamo ezahlukeneyo zombane lunokuqinisekiswa.

Ii-RCCB zihlala zifakelwa kwi-switchboard ephambili okanye kwindawo yokuqala kwesekethe. Olu lungiselelo luqinisekisa ukuba yonke isekethe ikhuselekile, kuquka zonke izixhobo kunye nezixhobo ezisezantsi. Kubalulekile ukuqaphela ukuba ukuze kubekho ukhuseleko oluphezulu, ii-RCCB kufuneka zivavanywe kwaye zigcinwe rhoqo. Uvavanyo oluqhelekileyo luqinisekisa ukuba izixhobo zihlala zikwimeko entle kwaye ziyaqhubeka nokubonelela ngokhuseleko olusebenzayo.

Kufuphi,ii-residual current breakers (RCCB)zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lobomi kunye nepropathi kunye nokuphepha iingozi zombane. Ngenxa yokukwazi kwazo ukubona nokuthintela iimpazamo zamandla aseleyo, zibonelela ngomgangatho ongenakuthelekiswa nanto wokhuseleko ngokuchasene nokutsha kombane kunye nomlilo. Uvakalelo lwazo kunye nokukwazi kwazo ukukhusela kwiisekethe ezimfutshane kunye nokugqithisa kuzenza zibe yinxalenye ebalulekileyo yalo naluphi na ukufakelwa kombane. Ukubekwa phambili kufuneka kunikwe ukugcinwa rhoqo kombane.Ii-RCCBukuqinisekisa imigangatho ephezulu yokhuseleko lombane. Khumbula,I-RCCBngumgcini wethu othembekileyo xa kufikwa kukhuseleko lombane.
