1. Intshayelelo yeIsaphuli seSekethe yangoku eshiyekileyo

I-Residual Current Circuit Breaker (RCCB) sisixhobo sokukhusela umbane esikhupha isiphaluka nanini na xa sibona ukungalingani phakathi kwemisinga ephilayo kunye nengathathi hlangothi. Oku kungalingani kubonisa ukuvuza kwangoku okuqukuqela emhlabeni, okunokuba yingozi ebantwini okanye kunokukhokelela kumlilo wombane.

Ngokungafaniyo nezixhobo eziqhelekileyo zokukhusela, ii-RCCBs azikhuseli ngokugqithiswa okanye iimeko zesiphaluka ezimfutshane. Endaweni yoko, indima yabo ephambili kukuqinisekisa ukhuseleko lomntu ngokufumanisa nokuba imisinga evuzayo encinci-kaninzi isezantsi njenge-30mA.

2. Isebenza njani iIsaphuli seSekethe yangoku eshiyekileyo

Umgaqo wokusebenza weResidual Current Circuit Breaker usekelwe kumthetho wangoku waseKirchhoff, othi i-current ingena kwisiphaluka kufuneka ilingane nokushiya kwangoku. Ukuba kukho nawuphi na umahluko, kubonisa ukuvuza.

Ngaphakathi kwe-RCCB, i-transformer yangoku isoloko ibeka iliso kubaqhubi abaphilayo nabangathathi hlangothi. Ngaphantsi kweemeko eziqhelekileyo, imimandla yamagnetic ikhansela enye kwenye. Nangona kunjalo, xa ukuvuza kusenzeka, ukungalingani kubangela indlela yohambo.

• Imeko eqhelekileyo: Phila ngoku = I-Neutral current
• Imeko yempazamo: Phila ngoku ≠ Umsinga ophakathi
• Intshukumo yohambo: Isekethe iyaqhawula ngoko nangoko (imizuzwana emingaphi)
