概述

ZW20-12FT系列型户(hu)外(wai)高压真(zhen)空(kong)断(duan)(duan)路器(qi)（以下(xia)简称断(duan)(duan)路器(qi)）为(wei)额定电(dian)压12kV,三相交流50Hz的(de)(de)(de)(de)户(hu)外(wai)配电(dian)设备(bei)。它采用真(zhen)空(kong)灭弧和SF6气(qi)(qi)体作(zuo)(zuo)为(wei)绝(jue)缘(yuan)介质，是ZW2O-12F型柱(zhu)上真(zhen)空(kong)断(duan)(duan)路器(qi)改进(jin)型产(chan)品。箱体采用了引进(jin)日本东芝公(gong)司(si)VSP5的(de)(de)(de)(de)气(qi)(qi)体密封、防爆、绝(jue)缘(yuan)结构(gou)技(ji)术(shu)，进(jin)出(chu)线导管也进(jin)行了密封性(xing)(xing)(xing)能(neng)改进(jin)，整体密封性(xing)(xing)(xing)能(neng)优良，内部充装的(de)(de)(de)(de)SF6气(qi)(qi)体不(bu)泄(xie)漏，不(bu)受个(ge)界环境影响;其弹簧操作(zuo)(zuo)机(ji)构(gou)进(jin)行了小(xiao)型化(hua)设计和可(ke)靠(kao)性(xing)(xing)(xing)和稳定性(xing)(xing)(xing)优化(hua)，采用直动链条主(zhu)传动和多级脱扣系统，动作(zuo)(zuo)可(ke)靠(kao)性(xing)(xing)(xing)和稳定性(xing)(xing)(xing)比(bi)国内传统的(de)(de)(de)(de)弹簧操作(zuo)(zuo)机(ji)构(gou)提高了好几倍;主(zhu)回路的(de)(de)(de)(de)轴与(yu)套之间的(de)(de)(de)(de)接触采用了内收外(wai)张式表链结构(gou)，主(zhu)回路的(de)(de)(de)(de)接触电(dian)阻小(xiao)、温升(sheng)低。所以，ZW20-12F型户(hu)外(wai)柱(zhu)上真(zhen)空(kong)断(duan)(duan)路器(qi)是一种免维护产(chan)品，是柱(zhu)上断(duan)(duan)路器(qi)中的(de)(de)(de)(de)佳(jia)品。

ZW20-12F较(jiao)ZW20-12F还增(zeng)加了过流保(bao)护(hu)、机构弹簧储(chu)能(neng)(neng)指示，并(bing)配备航空(kong)插座作(zuo)二次电(dian)(dian)(dian)气连接，便于(yu)与智能(neng)(neng)化控制(zhi)器相结合。优良(liang)的(de)电(dian)(dian)(dian)气和机械性能(neng)(neng)，使(shi)ZW20-12F型(xing)户外柱上真空(kong)断路(lu)器得到(dao)广泛的(de)应用(yong)。主要(yao)用(yong)于(yu)开(kai)断、关合10kV电(dian)(dian)(dian)力系(xi)(xi)统的(de)负荷电(dian)(dian)(dian)流及短路(lu)电(dian)(dian)(dian)流，适用(yong)于(yu)变电(dian)(dian)(dian)站及工矿企业配电(dian)(dian)(dian)系(xi)(xi)统中作(zuo)保(bao)护(hu)和控制(zhi)之用(yong)，更适用(yong)于(yu)电(dian)(dian)(dian)网频繁操(cao)作(zuo)的(de)场(chang)所。本(ben)产(chan)品与控制(zhi)器配套，具(ju)有(you)优良(liang)的(de)重合器功能(neng)(neng)，能(neng)(neng)满(man)足配电(dian)(dian)(dian)自动化系(xi)(xi)统要(yao)求。
