產品簡介(jie)：ZW20-12F 戶(hu)外(wai)高壓真空分界斷路(lu)器( 看(kan)門狗(gou)開關(guan)(guan)) 為額定電(dian)壓12kV，三相交流50Hz 的(de)戶(hu)外(wai)配(pei)電(dian)設(she)備。當12kV 配(pei)電(dian)線路(lu)T 型接線的(de)用(yong)戶(hu)內(nei)部(bu)發生故(gu)(gu)障(zhang)時(shi)(shi)(shi)，或雖然發生在(zai)用(yong)戶(hu)進線開關(guan)(guan)內(nei)側，但(dan)其(qi)保護動作時(shi)(shi)(shi)限與變(bian)電(dian)站(zhan)出線開關(guan)(guan)保護不(bu)當時(shi)(shi)(shi)，會(hui)造成變(bian)電(dian)站(zhan)出線開關(guan)(guan)保護分閘。如果(guo)故(gu)(gu)障(zhang)是長(chang)久性的(de)，變(bian)電(dian)站(zhan)重合不(bu)成功(gong)，則一個中壓用(yong)戶(hu)界內(nei)的(de)事(shi)(shi)故(gu)(gu)將使整條配(pei)電(dian)干線停(ting)電(dian)。這種電(dian)網中常見的(de)波(bo)及(ji)事(shi)(shi)故(gu)(gu)，將對社會(hui)造成重大損失。
概述
ZW20-12F 戶(hu)(hu)外(wai)高(gao)壓真空分界斷(duan)路(lu)器(qi)( 看門狗(gou)開關(guan)) 為額定電(dian)(dian)壓12kV，三相(xiang)交流(liu)50Hz 的(de)(de)戶(hu)(hu)外(wai)配電(dian)(dian)設備。當(dang)12kV 配電(dian)(dian)線(xian)(xian)路(lu)T 型接線(xian)(xian)的(de)(de)用(yong)戶(hu)(hu)內部發(fa)生故障時(shi)，或雖然發(fa)生在用(yong)戶(hu)(hu)進線(xian)(xian)開關(guan)內側，但其保護動作時(shi)限(xian)與變(bian)(bian)電(dian)(dian)站出線(xian)(xian)開關(guan)保護不當(dang)時(shi)，會(hui)造成(cheng)變(bian)(bian)電(dian)(dian)站出線(xian)(xian)開關(guan)保護分閘。如果(guo)故障是長久性(xing)的(de)(de)，變(bian)(bian)電(dian)(dian)站重(zhong)合不成(cheng)功，則一(yi)個中壓用(yong)戶(hu)(hu)界內的(de)(de)事故將使整(zheng)條配電(dian)(dian)干線(xian)(xian)停電(dian)(dian)。這(zhe)種電(dian)(dian)網(wang)中常見的(de)(de)波及事故，將對社會(hui)造成(cheng)重(zhong)大損失。
ZW20-12F 戶(hu)外(wai)高壓真空分界(jie)(jie)斷路器( 看門(men)狗開關(guan))，安裝于架空配(pei)電(dian)線(xian)路的(de)責任分界(jie)(jie)處(chu)則(ze)用(yong)戶(hu)進線(xian)的(de)前(qian)端，將會(hui)自動切除用(yong)戶(hu)內單(dan)相(xiang)接地故障和(he)相(xiang)間短路故障，避免用(yong)戶(hu)界(jie)(jie)內故障波及輸(shu)電(dian)干線(xian)，保證非故障用(yong)戶(hu)的(de)用(yong)電(dian)安全，提高用(yong)電(dian)可靠性。
