一、高低壓成套設備是什么
高壓成套設備(高壓配(pei)(pei)電(dian)(dian)(dian)(dian)柜)是(shi)指在(zai)電(dian)(dian)(dian)(dian)壓3kV及以(yi)上,頻(pin)率50Hz及以(yi)下的(de)電(dian)(dian)(dian)(dian)力(li)系(xi)統中(zhong)(zhong)運(yun)(yun)行(xing)的(de)戶(hu)內和(he)戶(hu)外(wai)交(jiao)流開(kai)關設(she)備(bei)。主(zhu)要用于電(dian)(dian)(dian)(dian)力(li)系(xi)統(包括(kuo)發電(dian)(dian)(dian)(dian)廠(chang)、變電(dian)(dian)(dian)(dian)站、輸配(pei)(pei)電(dian)(dian)(dian)(dian)線路和(he)工礦企業等用戶(hu))的(de)控制和(he)保護,既可(ke)(ke)根據電(dian)(dian)(dian)(dian)網(wang)運(yun)(yun)行(xing)需要將(jiang)一部分(fen)(fen)電(dian)(dian)(dian)(dian)力(li)設(she)備(bei)或線路投入或退出(chu)運(yun)(yun)行(xing),也可(ke)(ke)在(zai)電(dian)(dian)(dian)(dian)力(li)設(she)備(bei)或線路發生(sheng)故(gu)障(zhang)時將(jiang)故(gu)障(zhang)部分(fen)(fen)從電(dian)(dian)(dian)(dian)網(wang)快(kuai)速切除,從而(er)保證電(dian)(dian)(dian)(dian)網(wang)中(zhong)(zhong)無故(gu)障(zhang)部分(fen)(fen)的(de)正(zheng)常運(yun)(yun)行(xing)及設(she)備(bei)、運(yun)(yun)行(xing)維修人員的(de)安全(quan)(quan)。因此,高壓成(cheng)套設(she)備(bei)是(shi)非(fei)常重(zhong)要的(de)輸配(pei)(pei)電(dian)(dian)(dian)(dian)設(she)備(bei),其(qi)安全(quan)(quan)、可(ke)(ke)靠運(yun)(yun)行(xing)對電(dian)(dian)(dian)(dian)力(li)系(xi)統的(de)安全(quan)(quan)、有效運(yun)(yun)行(xing)具有十分(fen)(fen)重(zhong)要的(de)意義(yi)。
低壓(ya)(ya)(ya)成(cheng)套設(she)備(bei)是指380V及以下電(dian)壓(ya)(ya)(ya)等級(ji)中(zhong)使用的(de)成(cheng)套設(she)備(bei)。后(hou)者是從(cong)安全角度來考慮的(de),但二者并不矛(mao)盾,因為在(zai)發配電(dian)系(xi)統中(zhong),低壓(ya)(ya)(ya)電(dian)器是指380V配電(dian)系(xi)統,因此,在(zai)實際工(gong)作中(zhong),低壓(ya)(ya)(ya)成(cheng)套是指380V及以下電(dian)壓(ya)(ya)(ya)等級(ji)中(zhong)使用的(de)電(dian)器設(she)備(bei)。
二、高低壓成套設備包括哪些
