一、高低壓成套設備是什么

高壓成套設備（高(gao)壓(ya)配電(dian)(dian)(dian)(dian)柜）是指(zhi)在(zai)電(dian)(dian)(dian)(dian)壓(ya)3kV及以上(shang)，頻率50Hz及以下的(de)(de)電(dian)(dian)(dian)(dian)力系統(tong)中運(yun)(yun)行(xing)的(de)(de)戶內和(he)戶外交流開關設備(bei)(bei)。主要用(yong)于電(dian)(dian)(dian)(dian)力系統(tong)（包括發電(dian)(dian)(dian)(dian)廠、變電(dian)(dian)(dian)(dian)站、輸(shu)配電(dian)(dian)(dian)(dian)線(xian)路(lu)和(he)工礦企業等用(yong)戶）的(de)(de)控制和(he)保護，既可(ke)根據電(dian)(dian)(dian)(dian)網運(yun)(yun)行(xing)需要將(jiang)一部分電(dian)(dian)(dian)(dian)力設備(bei)(bei)或(huo)(huo)線(xian)路(lu)投入或(huo)(huo)退(tui)出運(yun)(yun)行(xing)，也可(ke)在(zai)電(dian)(dian)(dian)(dian)力設備(bei)(bei)或(huo)(huo)線(xian)路(lu)發生故(gu)障時將(jiang)故(gu)障部分從(cong)電(dian)(dian)(dian)(dian)網快(kuai)速(su)切除，從(cong)而保證電(dian)(dian)(dian)(dian)網中無故(gu)障部分的(de)(de)正常(chang)運(yun)(yun)行(xing)及設備(bei)(bei)、運(yun)(yun)行(xing)維修人(ren)員(yuan)的(de)(de)安全。因此(ci)，高(gao)壓(ya)成套設備(bei)(bei)是非常(chang)重要的(de)(de)輸(shu)配電(dian)(dian)(dian)(dian)設備(bei)(bei)，其安全、可(ke)靠運(yun)(yun)行(xing)對電(dian)(dian)(dian)(dian)力系統(tong)的(de)(de)安全、有效運(yun)(yun)行(xing)具(ju)有十分重要的(de)(de)意義。

低(di)壓(ya)成套(tao)設備(bei)是(shi)指380V及以下電(dian)(dian)壓(ya)等(deng)(deng)級中(zhong)(zhong)使用(yong)的(de)成套(tao)設備(bei)。后者是(shi)從安全角度來考慮的(de)，但二者并不矛盾，因為在發配(pei)電(dian)(dian)系統(tong)中(zhong)(zhong)，低(di)壓(ya)電(dian)(dian)器是(shi)指380V配(pei)電(dian)(dian)系統(tong)，因此，在實際工作中(zhong)(zhong)，低(di)壓(ya)成套(tao)是(shi)指380V及以下電(dian)(dian)壓(ya)等(deng)(deng)級中(zhong)(zhong)使用(yong)的(de)電(dian)(dian)器設備(bei)。
