2 I-Pole RCD eyinsalela ye-circuit breaker Uhlobo AC noma Uhlobo A RCCB JCRD2-125
I-JCR2-125 RCD iyisinqamuli samanje esizwelayo esiklanyelwe ukuvikela umsebenzisi kanye nempahla yakhe ekushayweni ugesi kanye nemililo engase ibe khona ngokuphula umsinga njengoba udlula kuyunithi yakho yabathengi/ibhokisi lokusabalalisa uma kwenzeka kuba nokungalingani okutholiwe noma ukuphazamiseka endleleni yamanje.
Isingeniso:
I-Residual-current device (RCD), i-residual-current circuit breaker (RCCB) iyisisetshenziswa sokuphepha sikagesi esiphula ngokushesha isekethe kagesi ngokuvuza kwamanje kuye phansi.Okokuvikela okokusebenza kanye nokunciphisa ingcuphe yokulimala kabi ngenxa yokushaqeka kukagesi okuqhubekayo.Ukulimala kungase kwenzeke kwezinye izimo, isibonelo uma umuntu ethola ukushaqeka kafushane ngaphambi kokuba isekethe kagesi ihlukaniswe, awe ngemva kokushaqeka, noma uma umuntu ethinta bobabili amakhondatha ngesikhathi esisodwa.
I-JCR2-125 iklanyelwe ukunqamula isifunda uma kukhona ukuvuza kwamanje.
I-JCR2-125 Imishini eyinsalela yamanje (ama-RCD) ikuvikela ekutholeni ukushaqeka kukagesi okubulalayo.Ukuvikelwa kwe-RCD kusindisa impilo futhi kuvikela emlilweni.Uma uthinta intambo engenalutho noma ezinye izingxenye ezibukhoma zeyunithi yomthengi, kuzogcina umsebenzisi wokugcina engalinyazwa.Uma isifaki sinqamula ikhebuli, izisetshenziswa zamanje ezisele zizocisha amandla agelezela emhlabeni.I-RCD izosetshenziswa njengedivaysi engenayo ephakela ugesi kuma-breaker circuit.Uma kwenzeka kuba nebhalansi kagesi, i-RCD iyaphuma futhi inqamule ukunikezwa kuma-breaker circuit.
Idivayisi yamanje eyinsalela noma eyaziwa kangcono njenge-RCD iyisisetshenziswa esibalulekile sokuphepha emhlabeni kagesi.I-RCD isetshenziswa ngokuyinhloko ukuvikela umuntu ekushayweni kagesi okuyingozi.Uma kukhona okungalungile ngomshini endlini, i-RCD isabela ngenxa yokwanda kwamandla futhi inqamule amandla kagesi.I-RCD yakhelwe ngokuyisisekelo ukuthi iphendule ngokushesha.Idivaysi yamanje eyinsalela yengamela amandla kagesi kanye nokushesha kwanoma yimuphi umsebenzi ongavamile idivayisi esabela ngayo ngokushesha.
Ama-RCD akhona ngezindlela ezahlukahlukene futhi asabela ngendlela ehlukile kuye ngobukhona bezingxenye ze-DC noma amaza ahlukene.Izinga lokuphepha abakunikezayo kuma-currents aphilayo likhulu kune-fuse evamile noma i-circuit breaker.Ama-RCD alandelayo ayatholakala nezimpawu ezifanele futhi umklami noma isifaki siyadingeka ukuze akhethe idivayisi efanelekile yohlelo lokusebenza oluthile.
Uhlobo S (Isikhathi Esibambezelekile)
I-Type S RCD iyidivayisi yamanje eyinsalela ye-sinusoidal ehlanganisa ukubambezeleka kwesikhathi.Ingafakwa enhla nomfula isuka ohlotsheni lwe-AC RCD ukuze inikeze ukukhetha.I-RCD ebambezeleke isikhathi ayikwazi ukusetshenziselwa ukuvikela okwengeziwe ngoba ngeke isebenze phakathi nesikhathi esidingekayo esingu-40 mS.
Thayipha i-AC
Uhlobo lwe-AC RCDs (Uhlobo Olujwayelekile), oluvame ukufakwa ezindlini, aklanyelwe ukusetshenziselwa ukushintshanisa i-sinusoidal residual current ukuze kuvikelwe okokusebenza okukwazi ukumelana naso, amandla noma inductive futhi engenazo izingxenye ze-elekthronikhi.
Ama-RCD Ohlobo Olujwayelekile awanakho ukubambezeleka kwesikhathi futhi asebenza ngaso leso sikhathi ekutholeni ukungalingani.
Uhlobo A
Ama-RCD ohlobo A asetshenziselwa ukushintshanisa i-sinusoidal residual current kanye ne-residual pulsating yamanje eqondile efika ku-6 mA.

Ngizihlola kanjani Izinhlobo ezahlukene ze-RCD?
Azikho izidingo ezengeziwe zokuthi isifaki sihlole ukusebenza okulungile ngenkathi singaphansi kwe-DC residual current.Lokhu kuhlola kwenziwa ngesikhathi senqubo yokukhiqiza futhi kubizwa ngokuthi ukuhlola uhlobo, okungahlukile endleleni okwamanje esithembele ngayo kuma-circuit-breaker ngaphansi kwezimo zamaphutha.Ama-RCD ohlobo A, B kanye no-F ahlolwa ngendlela efanayo ne-AC RCD.Imininingwane yenqubo yokuhlola kanye nezikhathi eziphezulu zokunqanyulwa kungatholakala ku-IET Guidance Note 3.
Kuthiwani uma ngithola Uhlobo lwe-AC RCD ngenkathi ngihlola ugesi ngesikhathi sombiko wesimo sokufakwa kukagesi?
Uma umhloli ekhathazekile ngokuthi i-DC eyinsalela ingase ithinte ukusebenza kohlobo lwe-AC RCDs, iklayenti kufanele laziswe.Iklayenti kufanele laziswe ngezingozi ezingase zivele futhi kuhlolwe inani lensalela yephutha le-DC okufanele lenziwe ukuze kunqunywe ukuthi i-RCD ikulungele yini ukuqhubeka nokusetshenziswa.Ngokuya ngenani lensalela yephutha le-DC, i-RCD evalwe amehlo yinsalela ye-DC fault current kungenzeka ingasebenzi okungaba yingozi njengokungabi nayo i-RCD efakwe kwasekuqaleni.
Ukuthembeka kwangaphakathi kwesevisi kwama-RCD
Ucwaningo oluningi ngokuthembeka kwangaphakathi kwenkonzo luye lwenziwa kuma-RCD afakwe ohlwini olubanzi lokufakwa olunikeza ukuqonda ngemiphumela izimo zemvelo nezinto zangaphandle ezingaba nazo ekusebenzeni kwe-RCD.
