一、高低壓成套設備是什么

高壓成套設備（高(gao)(gao)壓配電(dian)(dian)(dian)柜）是(shi)指在(zai)電(dian)(dian)(dian)壓3kV及以上，頻率(lv)50Hz及以下的(de)電(dian)(dian)(dian)力系(xi)統(tong)中運(yun)行(xing)(xing)的(de)戶(hu)(hu)內和戶(hu)(hu)外交流開關設(she)(she)備(bei)。主(zhu)要(yao)用于電(dian)(dian)(dian)力系(xi)統(tong)（包(bao)括發電(dian)(dian)(dian)廠、變(bian)電(dian)(dian)(dian)站、輸配電(dian)(dian)(dian)線(xian)(xian)路和工礦企業(ye)等(deng)用戶(hu)(hu)）的(de)控(kong)制和保護(hu)，既(ji)可根據電(dian)(dian)(dian)網(wang)運(yun)行(xing)(xing)需要(yao)將一部(bu)分(fen)電(dian)(dian)(dian)力設(she)(she)備(bei)或線(xian)(xian)路投入或退(tui)出運(yun)行(xing)(xing)，也可在(zai)電(dian)(dian)(dian)力設(she)(she)備(bei)或線(xian)(xian)路發生故(gu)障(zhang)時將故(gu)障(zhang)部(bu)分(fen)從電(dian)(dian)(dian)網(wang)快速(su)切除，從而保證電(dian)(dian)(dian)網(wang)中無故(gu)障(zhang)部(bu)分(fen)的(de)正常運(yun)行(xing)(xing)及設(she)(she)備(bei)、運(yun)行(xing)(xing)維修人員(yuan)的(de)安全。因此，高(gao)(gao)壓成套設(she)(she)備(bei)是(shi)非常重要(yao)的(de)輸配電(dian)(dian)(dian)設(she)(she)備(bei)，其安全、可靠運(yun)行(xing)(xing)對電(dian)(dian)(dian)力系(xi)統(tong)的(de)安全、有效運(yun)行(xing)(xing)具有十(shi)分(fen)重要(yao)的(de)意義。

低(di)(di)壓成套設(she)備(bei)是(shi)(shi)指(zhi)(zhi)380V及以下(xia)電(dian)(dian)(dian)壓等級中使(shi)用的(de)成套設(she)備(bei)。后(hou)者是(shi)(shi)從安全角度來(lai)考慮的(de)，但二者并不矛盾，因為在(zai)發配電(dian)(dian)(dian)系統中，低(di)(di)壓電(dian)(dian)(dian)器是(shi)(shi)指(zhi)(zhi)380V配電(dian)(dian)(dian)系統，因此(ci)，在(zai)實際工作(zuo)中，低(di)(di)壓成套是(shi)(shi)指(zhi)(zhi)380V及以下(xia)電(dian)(dian)(dian)壓等級中使(shi)用的(de)電(dian)(dian)(dian)器設(she)備(bei)。
