　　BLK52-63/4L防爆斷(duan)路器(qi)_4P帶(dai)漏電(dian)主要部(bu)件是(shi)個(ge)磁(ci)環感(gan)應(ying)器(qi),火(huo)線(xian)(xian)(xian)(xian)(xian)和零線(xian)(xian)(xian)(xian)(xian)采用并(bing)列繞(rao)法在(zai)(zai)磁(ci)環上纏繞(rao)幾(ji)圈(quan)(quan),在(zai)(zai)磁(ci)環上還有(you)個(ge)次級(ji)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan).當同一相的(de)火(huo)線(xian)(xian)(xian)(xian)(xian)和零線(xian)(xian)(xian)(xian)(xian)在(zai)(zai)正常(chang)工作時(shi),電(dian)生(sheng)的(de)磁(ci)通(tong)正好抵消,在(zai)(zai)次級(ji)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)不(bu)會感(gan)應(ying)出電(dian)壓.如(ru)果某(mou)一線(xian)(xian)(xian)(xian)(xian)有(you)漏電(dian),或未(wei)接零線(xian)(xian)(xian)(xian)(xian),在(zai)(zai)磁(ci)環中通(tong)過(guo)(guo)的(de)火(huo)線(xian)(xian)(xian)(xian)(xian)和零線(xian)(xian)(xian)(xian)(xian)的(de)電(dian)流就會不(bu)平衡,而產生(sheng)穿過(guo)(guo)磁(ci)環的(de)磁(ci)通(tong),在(zai)(zai)次級(ji)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)中感(gan)應(ying)出電(dian)壓,通(tong)過(guo)(guo)電(dian)磁鐵使脫扣器動作(zuo)跳閘.
