高(gao)壓低(di)壓預裝式(shi)箱式(shi)變電(dian)(dian)站，是將高(gao)壓電(dian)(dian)器設備、變壓器、低(di)壓電(dian)(dian)器設備等組合成緊湊型成套配電(dian)(dian)裝置，用于城(cheng)市高(gao)層建筑、城(cheng)鄉建筑、居民小(xiao)區、技術開發區、中小(xiao)型工廠、礦山油(you)田以及(ji)臨時施工用電(dian)(dian)等場所，作配電(dian)(dian)系統中接(jie)受和分配電(dian)(dian)能(neng)之用。
高壓(ya)(ya)低壓(ya)(ya)預裝式箱式變電(dian)(dian)(dian)站，是將高壓(ya)(ya)電(dian)(dian)(dian)器(qi)設(she)備(bei)、變壓(ya)(ya)器(qi)、低壓(ya)(ya)電(dian)(dian)(dian)器(qi)設(she)備(bei)等(deng)組合成(cheng)緊湊(cou)型成(cheng)套配電(dian)(dian)(dian)裝置，用于城市(shi)高層(ceng)建(jian)筑(zhu)、城鄉建(jian)筑(zhu)、居民小(xiao)區(qu)、技術(shu)開發(fa)區(qu)、中小(xiao)型工廠、礦山油田(tian)以及(ji)臨時施工用電(dian)(dian)(dian)等(deng)場所，作配電(dian)(dian)(dian)系統中接受和(he)分配電(dian)(dian)(dian)能之用。
高壓低壓預裝(zhuang)式(shi)(shi)箱(xiang)式(shi)(shi)變電(dian)(dian)站，具(ju)有成套(tao)性強、體積小(xiao)、結構緊湊、運行安(an)全可靠、維護方便、以(yi)及(ji)可移動(dong)等特點(dian)，與常規(gui)土建(jian)式(shi)(shi)變電(dian)(dian)站相比，同(tong)容量的箱(xiang)式(shi)(shi)變電(dian)(dian)站占地面積通常僅為(wei)常規(gui)變電(dian)(dian)站的1/10～1/5，大大減少了(le)設計工(gong)作量及(ji)施工(gong)量，減少了(le)建(jian)設費用。在(zai)配(pei)電(dian)(dian)系統中，可用于環(huan)網(wang)配(pei)電(dian)(dian)系統，也(ye)可用于雙電(dian)(dian)源或放射(she)終(zhong)端配(pei)電(dian)(dian)系統，是目前城鄉變電(dian)(dian)站建(jian)設和改造(zao)的新成套(tao)設備。
高壓(ya)(ya)低壓(ya)(ya)預裝式箱(xiang)式變電站符(fu)合SD320-1992《箱(xiang)式變電站技(ji)術條件》和GB/T17467-1998《高壓(ya)(ya)／低壓(ya)(ya)預裝式變電站》的標準。
