高壓配電柜的(de)(de)走(zou)電(dian)(dian)保(bao)護電(dian)(dian)源(yuan)開(kai)(kai)(kai)關(guan)(guan)的(de)(de)原理：走(zou)電(dian)(dian)保(bao)護器的(de)(de)工作中(zhong)電(dian)(dian)路(lu)原理圖(tu)。LH為(wei)零序(xu)電(dian)(dian)流電(dian)(dian)壓(ya)(ya)互(hu)感(gan)器，它由坡莫合金為(wei)原材料(liao)的(de)(de)變壓(ya)(ya)器鐵芯，和繞在(zai)(zai)環形變壓(ya)(ya)器鐵芯上的(de)(de)二次(ci)電(dian)(dian)磁(ci)線(xian)(xian)圈構成檢驗(yan)元器件(jian)。開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)源(yuan)火線(xian)(xian)零線(xian)(xian)和中(zhong)性(xing)點(dian)越(yue)過圓(yuan)洞變成零序(xu)互(hu)感(gan)器的(de)(de)一次(ci)電(dian)(dian)磁(ci)線(xian)(xian)圈。電(dian)(dian)壓(ya)(ya)互(hu)感(gan)器的(de)(de)后側小組出(chu)線(xian)(xian)即是保(bao)護范疇(chou)。走(zou)電(dian)(dian)保(bao)護電(dian)(dian)源(yuan)開(kai)(kai)(kai)關(guan)(guan)的(de)(de)功效:1、當電(dian)(dian)器設備(bei)或路(lu)線(xian)(xian)產生走(zou)電(dian)(dian)或接地(di)裝置(zhi)常(chang)見故障時，能(neng)(neng)在(zai)(zai)人并未碰觸(chu)(chu)以前就把開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)源(yuan)斷(duan)開(kai)(kai)(kai)。2、當身體(ti)碰觸(chu)(chu)感(gan)應(ying)起電(dian)(dian)的(de)(de)物件(jian)時，能(neng)(neng)在(zai)(zai)011s內斷(duan)開(kai)(kai)(kai)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)源(yuan)，進(jin)而緩解電(dian)(dian)流量(liang)對(dui)身體(ti)的(de)(de)損(sun)害水平。3、能(neng)(neng)夠避免 因走(zou)電(dian)(dian)而造成的(de)(de)安全事故。
