高壓成套設(she)(she)備(bei)(高壓配電(dian)(dian)(dian)(dian)(dian)柜)是指在電(dian)(dian)(dian)(dian)(dian)壓3kV及(ji)以上(shang),頻率50Hz及(ji)以下的電(dian)(dian)(dian)(dian)(dian)力系統(tong)(tong)中運(yun)行(xing)(xing)(xing)的戶(hu)內和(he)戶(hu)外交流開關(guan)設(she)(she)備(bei)。主要用(yong)于電(dian)(dian)(dian)(dian)(dian)力系統(tong)(tong)(包(bao)括(kuo)發(fa)電(dian)(dian)(dian)(dian)(dian)廠、變電(dian)(dian)(dian)(dian)(dian)站、輸配電(dian)(dian)(dian)(dian)(dian)線(xian)路(lu)(lu)和(he)工礦(kuang)企業等用(yong)戶(hu))的控制和(he)保(bao)護,既可根(gen)據電(dian)(dian)(dian)(dian)(dian)網運(yun)行(xing)(xing)(xing)需要將一部分電(dian)(dian)(dian)(dian)(dian)力設(she)(she)備(bei)或(huo)線(xian)路(lu)(lu)投入或(huo)退出運(yun)行(xing)(xing)(xing),也可在電(dian)(dian)(dian)(dian)(dian)力設(she)(she)備(bei)或(huo)線(xian)路(lu)(lu)發(fa)生故(gu)障(zhang)時將故(gu)障(zhang)部分從電(dian)(dian)(dian)(dian)(dian)網快(kuai)速切除,從而保(bao)證(zheng)電(dian)(dian)(dian)(dian)(dian)網中無故(gu)障(zhang)部分的正(zheng)常運(yun)行(xing)(xing)(xing)及(ji)設(she)(she)備(bei)、運(yun)行(xing)(xing)(xing)維修人員的安(an)全。因此,高壓成套設(she)(she)備(bei)是非常重要的輸配電(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei),其安(an)全、可靠(kao)運(yun)行(xing)(xing)(xing)對(dui)電(dian)(dian)(dian)(dian)(dian)力系統(tong)(tong)的安(an)全、有效(xiao)運(yun)行(xing)(xing)(xing)具(ju)有十分重要的意義。
低(di)壓(ya)(ya)成套設(she)備是(shi)指(zhi)380V及(ji)(ji)以下(xia)電(dian)壓(ya)(ya)等(deng)級中(zhong)使用的(de)成套設(she)備。后(hou)者(zhe)是(shi)從安全角度來(lai)考慮(lv)的(de),但(dan)-者(zhe)并不矛盾,因為在發(fa)配(pei)電(dian)系統(tong)中(zhong),低(di)壓(ya)(ya)電(dian)器是(shi)指(zhi)380V配(pei)電(dian)系統(tong),因此,在實際工作(zuo)中(zhong),低(di)壓(ya)(ya)成套是(shi)指(zhi)380V及(ji)(ji)以下(xia)電(dian)壓(ya)(ya)等(deng)級中(zhong)使用的(de)電(dian)器設(she)備。
