2 Pole RCD na yanzu mai jujjuyawa Nau'in AC ko Nau'in A RCCB JCRD2-125
JCR2-125 RCD wani ƙwanƙwasa ne na yanzu wanda aka ƙera don kare mai amfani da dukiyoyinsu daga girgiza wutar lantarki da yuwuwar gobara ta hanyar karya na yanzu kamar yadda yake wucewa ta sashin mabukaci/akwatin rarrabawa a yayin da aka gano rashin daidaituwa ko rushewa ga hanyar yanzu.
Gabatarwa:
Na'urar saura na yanzu (RCD), saura-current circuit breaker (RCCB) na'urar aminci ce ta lantarki wacce ke karya da'irar lantarki da sauri tare da ɗigogi zuwa ƙasa.Shi ne don kare kayan aiki da kuma rage haɗarin mummunan lahani daga girgiza wutar lantarki mai gudana.Har ila yau akwai rauni a wasu lokuta, misali idan mutum ya sami ɗan girgiza kafin a keɓe wutar lantarki, ya faɗi bayan ya sami girgiza, ko kuma idan mutum ya taɓa masu gudanarwa a lokaci guda.
An tsara JCR2-125 don cire haɗin da'irar idan akwai ɗigogi na halin yanzu.
JCR2-125 Ragowar na'urori na yanzu (RCDs) suna hana ku samun mugunyar girgizar lantarki.Kariyar RCD ita ce ceton rai kuma tana kariya daga gobara.Idan ka taɓa waya mara amfani ko wasu abubuwan rayuwa na rukunin mabukaci, zai kiyaye ƙarshen mai amfani daga cutarwa.Idan mai sakawa ya yanke ta hanyar kebul, sauran na'urori na yanzu zasu kashe wutar da ke gudana zuwa ƙasa.Za a yi amfani da RCD azaman na'urar da ke shigowa wacce ke ciyar da wutar lantarki zuwa masu watsewar kewaye.A cikin yanayin ma'auni na lantarki, RCD tana fita kuma ta cire haɗin kayan aiki zuwa masu watsewar kewayawa.
Ragowar na'urar yanzu ko wacce aka fi sani da RCD babbar na'urar aminci ce a duniyar lantarki.Ana amfani da RCD da farko don kare ɗan adam daga girgizar lantarki mai haɗari.Idan akwai lahani tare da na'ura a cikin gidan, RCD yana amsawa saboda yawan wutar lantarki kuma yana cire haɗin wutar lantarki.RCD an ƙera shi da gaske don amsa da sauri.Ragowar na'urar tana kula da wutar lantarki da take duk wani mummunan aiki da na'urar ta yi cikin sauri.

Nau'in S (An jinkirta lokaci)
Nau'in S RCD shine na'urar saura na sinusoidal na yanzu wanda ya haɗa da jinkirin lokaci.Ana iya shigar dashi sama daga Nau'in AC RCD don samar da zaɓi.Ba za a iya amfani da RCD da aka jinkirta lokaci don ƙarin kariya ba saboda ba zai yi aiki a cikin lokacin da ake buƙata na 40 mS ba.
Nau'in AC
Nau'in AC RCDs (Nau'in Gabaɗaya), waɗanda aka fi shigar da su a cikin gidaje, an ƙirƙira su don amfani da su don canza ragowar sinusoidal na yanzu don kare kayan aikin da ke da juriya, mai ƙarfi ko inductive kuma ba tare da kowane kayan lantarki ba.
Gabaɗaya Nau'in RCDs ba su da jinkirin lokaci kuma suna aiki nan take akan gano rashin daidaituwa.
Nau'in A
Ana amfani da nau'in RCDs na A don musanya ragowar sinusoidal na yanzu da kuma saura pulsating kai tsaye halin yanzu har zuwa 6 mA.
