箱體的主要設備使用家(jia)用電(dian)(dian)器(qi)，例如(ru)真空(kong)控(kong)制柜，干式(shi)變(bian)(bian)壓器(qi)，干式(shi)變(bian)(bian)壓器(qi)，真空(kong)斷(duan)路器(qi)（彈簧(huang)操(cao)(cao)作機(ji)構），并(bing)且(qie)產品沒有裸露的帶電(dian)(dian)部件。它(ta)是全邊(bian)緣結構，可完全導致零電(dian)(dian)擊事故。整個站可以實(shi)現高度安全的無油運行。第二(er)次(ci)，集成到微計算(suan)機(ji)中(zhong)的自動化系統用于實(shi)現無人值守(shou)的操(cao)(cao)作。

建(jian)議出(chu)于美(mei)觀原因，應使(shi)用鋼(gang)(gang)管(guan)(guan)敷設10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)口(kou)。變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)中的(de)10 kV箱式配(pei)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)外(wai)殼(ke)通常用水泥鋪成(cheng)，并且10 kV線(xian)路終端(duan)通常在變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)壁外(wai)10 m。如果將電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)直(zhi)接埋(mai)在地下并引(yin)到電(dian)(dian)(dian)(dian)(dian)線(xian)桿上，則很難(nan)進行維護(hu)。因此，應將10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)插座(zuo)穿過(guo)鋼(gang)(gang)管(guan)(guan)，以使(shi)用戶(hu)易于維護(hu)。如果10 kV線(xian)路的(de)連(lian)接極遠離變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，則必須通過(guo)鋼(gang)(gang)管(guan)(guan)將10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)出(chu)線(xian)口(kou)從(cong)機殼(ke)鋪設到變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)墻壁。在電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)口(kou)末端(duan)的(de)線(xian)路接線(xian)柱上安裝了(le)新的(de)電(dian)(dian)(dian)(dian)(dian)涌保(bao)護(hu)器(qi)，以避免過(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。生產廠(chang)家建議(yi)它(ta)還可(ke)以(yi)安裝在35 kV設備(bei)，10 kV設備(bei)的(de)室外以(yi)及控制(zhi)和保(bao)護系(xi)統箱(xiang)體。這種(zhong)組合(he)方法(fa)特別適(shi)用(yong)于將舊(jiu)站點轉(zhuan)換(huan)為(wei)農村電(dian)(dian)(dian)(dian)網的(de)轉(zhuan)換(huan)，即原始的(de)35 kV設備(bei)不動，僅安裝10 kV配電(dian)(dian)(dian)(dian)箱(xiang)。可(ke)以(yi)滿足無人值守(shou)的(de)要(yao)求。如果電(dian)(dian)(dian)(dian)氣設備(bei)在運行過(guo)(guo)程中被接地(di)(di)阻塞，則電(dian)(dian)(dian)(dian)流將通過(guo)(guo)接地(di)(di)體流入地(di)(di)下。實驗表(biao)明，穿過(guo)(guo)地(di)(di)球(qiu)的(de)電(dian)(dian)(dian)(dian)位(wei)為(wei)零，因(yin)此穿過(guo)(guo)地(di)(di)球(qiu)的(de)電(dian)(dian)(dian)(dian)位(wei)為(wei)零。因(yin)此，在施(shi)加電(dian)(dian)(dian)(dian)能時要(yao)使用(yong)手動操作，以(yi)防止所有接觸體接地(di)(di)。無論環(huan)境(jing)如何，電(dian)(dian)(dian)(dian)勢(shi)均(jun)為(wei)零，并且用(yong)電(dian)(dian)(dian)(dian)安全(quan)。因(yin)此，接地(di)(di)的(de)主要(yao)作用(yong)是保(bao)護人員和設備(bei)的(de)安全(quan)。
