概述

ZW20-12F 戶(hu)外高壓(ya)真空分界(jie)斷路(lu)器( 看門(men)狗開關) 為(wei)額定電(dian)(dian)壓(ya)12kV，三相交流50Hz 的戶(hu)外配(pei)電(dian)(dian)設備。當12kV 配(pei)電(dian)(dian)線(xian)路(lu)T 型接線(xian)的用戶(hu)內部發(fa)生(sheng)故(gu)(gu)障時(shi)(shi)，或雖然發(fa)生(sheng)在用戶(hu)進線(xian)開關內側(ce)，但其保(bao)護動(dong)作時(shi)(shi)限(xian)與變電(dian)(dian)站出線(xian)開關保(bao)護不(bu)當時(shi)(shi)，會造成變電(dian)(dian)站出線(xian)開關保(bao)護分閘。如果故(gu)(gu)障是長(chang)久(jiu)性(xing)的，變電(dian)(dian)站重(zhong)(zhong)合不(bu)成功，則一個(ge)中壓(ya)用戶(hu)界(jie)內的事(shi)故(gu)(gu)將使(shi)整條(tiao)配(pei)電(dian)(dian)干線(xian)停電(dian)(dian)。這種電(dian)(dian)網中常見(jian)的波(bo)及事(shi)故(gu)(gu)，將對社會造成重(zhong)(zhong)大損失。

ZW20-12F 戶外(wai)高壓真空分界斷(duan)路器( 看門狗開關)，安(an)裝(zhuang)于架空配電線(xian)(xian)路的(de)責任分界處則用(yong)戶進線(xian)(xian)的(de)前端，將會自(zi)動切除用(yong)戶內單相接地故(gu)障(zhang)和相間短路故(gu)障(zhang)，避免用(yong)戶界內故(gu)障(zhang)波及(ji)輸(shu)電干線(xian)(xian)，保(bao)證非故(gu)障(zhang)用(yong)戶的(de)用(yong)電安(an)全，提高用(yong)電可靠性(xing)。
