箱體(ti)的(de)主要設備使用家(jia)用電(dian)器，例如真(zhen)空控制(zhi)柜，干(gan)(gan)式(shi)變壓(ya)(ya)器，干(gan)(gan)式(shi)變壓(ya)(ya)器，真(zhen)空斷路器（彈簧操作機構），并且產(chan)品沒有裸(luo)露的(de)帶電(dian)部件(jian)。它是全(quan)邊緣結構，可(ke)完(wan)全(quan)導致零電(dian)擊事(shi)故。整個站可(ke)以實現高(gao)度安(an)全(quan)的(de)無油(you)運行。第二次，集成到(dao)微(wei)計算機中的(de)自動化系(xi)統用于實現無人值守的(de)操作。

建議出(chu)于(yu)美觀(guan)原因(yin)，應(ying)使(shi)用(yong)(yong)鋼管(guan)敷設10 kV電(dian)(dian)(dian)纜出(chu)口。變電(dian)(dian)(dian)站(zhan)(zhan)中的10 kV箱式配電(dian)(dian)(dian)站(zhan)(zhan)外殼(ke)通(tong)(tong)常(chang)用(yong)(yong)水泥鋪成，并(bing)且(qie)10 kV線路(lu)終端通(tong)(tong)常(chang)在(zai)變電(dian)(dian)(dian)站(zhan)(zhan)壁(bi)外10 m。如(ru)果(guo)將(jiang)(jiang)電(dian)(dian)(dian)纜直接(jie)埋在(zai)地下并(bing)引(yin)到電(dian)(dian)(dian)線桿上，則很難進行維護。因(yin)此，應(ying)將(jiang)(jiang)10 kV電(dian)(dian)(dian)纜插座穿(chuan)過(guo)鋼管(guan)，以(yi)使(shi)用(yong)(yong)戶(hu)易(yi)于(yu)維護。如(ru)果(guo)10 kV線路(lu)的連接(jie)極遠離變電(dian)(dian)(dian)站(zhan)(zhan)，則必須通(tong)(tong)過(guo)鋼管(guan)將(jiang)(jiang)10 kV電(dian)(dian)(dian)纜的出(chu)線口從機殼(ke)鋪設到變電(dian)(dian)(dian)站(zhan)(zhan)的墻壁(bi)。在(zai)電(dian)(dian)(dian)纜出(chu)口末端的線路(lu)接(jie)線柱上安裝了新的電(dian)(dian)(dian)涌保(bao)護器(qi)，以(yi)避免過(guo)電(dian)(dian)(dian)壓。

由于箱式變電站的緊湊結構，每個箱體代表一個獨立的系統，使組合方法變得靈活且可互換。我們可以使用所有箱式設備，即在所有箱體安裝35 kV和10 kV設備，以形成一個完整的箱式變電站。生產廠家建(jian)議它還(huan)可(ke)以安(an)裝在(zai)35 kV設(she)備(bei)(bei)(bei)，10 kV設(she)備(bei)(bei)(bei)的(de)(de)(de)室外以及控制和保護(hu)系統(tong)箱體。這種組合(he)方(fang)法(fa)特別適(shi)用(yong)(yong)于將舊站點轉(zhuan)換(huan)為(wei)農村電(dian)(dian)(dian)網的(de)(de)(de)轉(zhuan)換(huan)，即原始的(de)(de)(de)35 kV設(she)備(bei)(bei)(bei)不動，僅安(an)裝10 kV配(pei)電(dian)(dian)(dian)箱。可(ke)以滿(man)足(zu)無(wu)人值守的(de)(de)(de)要(yao)求。如果電(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)在(zai)運(yun)行過(guo)程中被接地(di)阻塞，則電(dian)(dian)(dian)流將通過(guo)接地(di)體流入地(di)下(xia)。實(shi)驗(yan)表明(ming)，穿過(guo)地(di)球的(de)(de)(de)電(dian)(dian)(dian)位為(wei)零(ling)，因此穿過(guo)地(di)球的(de)(de)(de)電(dian)(dian)(dian)位為(wei)零(ling)。因此，在(zai)施(shi)加電(dian)(dian)(dian)能(neng)時(shi)要(yao)使用(yong)(yong)手(shou)動操作，以防止(zhi)所有(you)接觸體接地(di)。無(wu)論環境如何，電(dian)(dian)(dian)勢均為(wei)零(ling)，并且用(yong)(yong)電(dian)(dian)(dian)安(an)全。因此，接地(di)的(de)(de)(de)主要(yao)作用(yong)(yong)是(shi)保護(hu)人員(yuan)和設(she)備(bei)(bei)(bei)的(de)(de)(de)安(an)全。
