箱體的(de)(de)主要設備使(shi)用家用電(dian)器(qi)，例如(ru)真(zhen)空控制柜，干(gan)式變壓器(qi)，干(gan)式變壓器(qi)，真(zhen)空斷路(lu)器(qi)（彈簧操作(zuo)機構(gou)），并且產(chan)品(pin)沒有(you)裸露的(de)(de)帶(dai)電(dian)部件。它是(shi)全(quan)邊緣結構(gou)，可(ke)完(wan)全(quan)導致零電(dian)擊事故。整個站可(ke)以實現高度安(an)全(quan)的(de)(de)無(wu)油(you)運行。第(di)二(er)次，集成到微計(ji)算機中的(de)(de)自動化系(xi)統用于實現無(wu)人(ren)值(zhi)守的(de)(de)操作(zuo)。

建議出(chu)(chu)于(yu)美觀原因，應使用(yong)鋼管(guan)敷設(she)10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)(chu)口。變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)中的(de)10 kV箱式配電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)外殼通(tong)常用(yong)水泥鋪成(cheng)，并且(qie)10 kV線路終端(duan)通(tong)常在變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)壁外10 m。如果(guo)將電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)直接埋在地下并引(yin)到電(dian)(dian)(dian)(dian)(dian)線桿上，則很難進(jin)行(xing)維護。因此，應將10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)插座穿(chuan)過(guo)鋼管(guan)，以(yi)使用(yong)戶易于(yu)維護。如果(guo)10 kV線路的(de)連接極遠離變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，則必須通(tong)過(guo)鋼管(guan)將10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)出(chu)(chu)線口從(cong)機殼鋪設(she)到變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)墻(qiang)壁。在電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)(chu)口末端(duan)的(de)線路接線柱上安(an)裝了新的(de)電(dian)(dian)(dian)(dian)(dian)涌保護器，以(yi)避免過(guo)電(dian)(dian)(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(sheng)產(chan)廠(chang)家建議它(ta)還可以(yi)安裝(zhuang)在35 kV設備(bei)(bei)，10 kV設備(bei)(bei)的(de)(de)室(shi)外以(yi)及控(kong)制和保護(hu)系統(tong)箱體(ti)。這(zhe)種組合(he)方法(fa)特別(bie)適用(yong)于(yu)將舊站(zhan)點轉換(huan)為(wei)(wei)農村電(dian)(dian)(dian)(dian)網(wang)的(de)(de)轉換(huan)，即原(yuan)始的(de)(de)35 kV設備(bei)(bei)不動，僅安裝(zhuang)10 kV配電(dian)(dian)(dian)(dian)箱。可以(yi)滿足無人值守的(de)(de)要求。如果電(dian)(dian)(dian)(dian)氣(qi)設備(bei)(bei)在運行過程(cheng)中被接地阻塞，則電(dian)(dian)(dian)(dian)流將通過接地體(ti)流入地下。實驗表明，穿(chuan)過地球的(de)(de)電(dian)(dian)(dian)(dian)位(wei)為(wei)(wei)零(ling)，因此(ci)穿(chuan)過地球的(de)(de)電(dian)(dian)(dian)(dian)位(wei)為(wei)(wei)零(ling)。因此(ci)，在施加電(dian)(dian)(dian)(dian)能時要使用(yong)手動操作(zuo)，以(yi)防止所有接觸體(ti)接地。無論環境如何(he)，電(dian)(dian)(dian)(dian)勢均為(wei)(wei)零(ling)，并且用(yong)電(dian)(dian)(dian)(dian)安全(quan)。因此(ci)，接地的(de)(de)主要作(zuo)用(yong)是保護(hu)人員和設備(bei)(bei)的(de)(de)安全(quan)。
