一、高低壓成套設備是什么
高壓成套設備(高壓(ya)配(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju))是(shi)指在電(dian)(dian)(dian)(dian)壓(ya)3kV及(ji)以上,頻率50Hz及(ji)以下的(de)(de)電(dian)(dian)(dian)(dian)力系(xi)統(tong)中運(yun)行的(de)(de)戶(hu)內和(he)(he)戶(hu)外交流開關設(she)(she)備(bei)。主要用(yong)于(yu)電(dian)(dian)(dian)(dian)力系(xi)統(tong)(包括發電(dian)(dian)(dian)(dian)廠(chang)、變電(dian)(dian)(dian)(dian)站、輸(shu)配(pei)(pei)電(dian)(dian)(dian)(dian)線(xian)路(lu)和(he)(he)工礦(kuang)企(qi)業等用(yong)戶(hu))的(de)(de)控制和(he)(he)保護,既可根據電(dian)(dian)(dian)(dian)網運(yun)行需要將一部分電(dian)(dian)(dian)(dian)力設(she)(she)備(bei)或(huo)線(xian)路(lu)投入(ru)或(huo)退出運(yun)行,也可在電(dian)(dian)(dian)(dian)力設(she)(she)備(bei)或(huo)線(xian)路(lu)發生故障時將故障部分從電(dian)(dian)(dian)(dian)網快速切除,從而保證電(dian)(dian)(dian)(dian)網中無故障部分的(de)(de)正(zheng)常運(yun)行及(ji)設(she)(she)備(bei)、運(yun)行維修人員的(de)(de)安全。因此(ci),高壓(ya)成(cheng)套(tao)設(she)(she)備(bei)是(shi)非常重要的(de)(de)輸(shu)配(pei)(pei)電(dian)(dian)(dian)(dian)設(she)(she)備(bei),其安全、可靠(kao)運(yun)行對電(dian)(dian)(dian)(dian)力系(xi)統(tong)的(de)(de)安全、有(you)效運(yun)行具(ju)有(you)十分重要的(de)(de)意(yi)義。
低(di)壓(ya)成套設備是指(zhi)380V及以下電(dian)壓(ya)等級中使(shi)用的(de)成套設備。后者(zhe)是從安(an)全角度來考慮(lv)的(de),但二者(zhe)并不矛(mao)盾,因(yin)為在發配電(dian)系(xi)統(tong)中,低(di)壓(ya)電(dian)器(qi)是指(zhi)380V配電(dian)系(xi)統(tong),因(yin)此,在實際工(gong)作中,低(di)壓(ya)成套是指(zhi)380V及以下電(dian)壓(ya)等級中使(shi)用的(de)電(dian)器(qi)設備。
