箱體(ti)的(de)主要設(she)備使用(yong)家用(yong)電(dian)器(qi)(qi)，例如真(zhen)空(kong)(kong)控制柜，干式變(bian)壓器(qi)(qi)，干式變(bian)壓器(qi)(qi)，真(zhen)空(kong)(kong)斷路器(qi)(qi)（彈(dan)簧(huang)操(cao)作機構），并(bing)且產品沒有裸露的(de)帶(dai)電(dian)部件。它是全邊緣結構，可完全導致零電(dian)擊事故。整個站(zhan)可以(yi)實(shi)現高度安全的(de)無(wu)油運行。第二次(ci)，集成(cheng)到微計算機中的(de)自動化系(xi)統用(yong)于實(shi)現無(wu)人值守的(de)操(cao)作。

建議出于美觀原因，應(ying)使用鋼管敷設10 kV電(dian)(dian)(dian)纜(lan)(lan)出口(kou)(kou)。變電(dian)(dian)(dian)站中的10 kV箱式配(pei)電(dian)(dian)(dian)站外殼通常用水泥鋪(pu)成，并(bing)且10 kV線(xian)(xian)(xian)路終端(duan)通常在變電(dian)(dian)(dian)站壁(bi)(bi)外10 m。如果將電(dian)(dian)(dian)纜(lan)(lan)直接(jie)(jie)埋在地下并(bing)引到電(dian)(dian)(dian)線(xian)(xian)(xian)桿上，則很難進行維護(hu)(hu)(hu)。因此，應(ying)將10 kV電(dian)(dian)(dian)纜(lan)(lan)插座(zuo)穿過鋼管，以(yi)使用戶(hu)易于維護(hu)(hu)(hu)。如果10 kV線(xian)(xian)(xian)路的連接(jie)(jie)極遠(yuan)離(li)變電(dian)(dian)(dian)站，則必須通過鋼管將10 kV電(dian)(dian)(dian)纜(lan)(lan)的出線(xian)(xian)(xian)口(kou)(kou)從機殼鋪(pu)設到變電(dian)(dian)(dian)站的墻(qiang)壁(bi)(bi)。在電(dian)(dian)(dian)纜(lan)(lan)出口(kou)(kou)末端(duan)的線(xian)(xian)(xian)路接(jie)(jie)線(xian)(xian)(xian)柱上安(an)裝了(le)新的電(dian)(dian)(dian)涌保(bao)護(hu)(hu)(hu)器，以(yi)避免(mian)過電(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。生產廠家建議它還可(ke)以安(an)(an)裝(zhuang)在35 kV設(she)備，10 kV設(she)備的(de)(de)室外以及(ji)控制和(he)(he)保護(hu)系(xi)統箱體(ti)。這種(zhong)組合方法特(te)別適用(yong)于(yu)將舊站點轉換為(wei)農村(cun)電(dian)(dian)(dian)網的(de)(de)轉換，即原始(shi)的(de)(de)35 kV設(she)備不(bu)動，僅(jin)安(an)(an)裝(zhuang)10 kV配電(dian)(dian)(dian)箱。可(ke)以滿足無人值(zhi)守的(de)(de)要(yao)求。如果(guo)電(dian)(dian)(dian)氣設(she)備在運行(xing)過(guo)(guo)程中被接地(di)(di)阻塞(sai)，則電(dian)(dian)(dian)流(liu)將通(tong)過(guo)(guo)接地(di)(di)體(ti)流(liu)入地(di)(di)下(xia)。實驗表明，穿(chuan)過(guo)(guo)地(di)(di)球的(de)(de)電(dian)(dian)(dian)位為(wei)零，因此穿(chuan)過(guo)(guo)地(di)(di)球的(de)(de)電(dian)(dian)(dian)位為(wei)零。因此，在施(shi)加電(dian)(dian)(dian)能時要(yao)使用(yong)手動操作(zuo)，以防(fang)止所有接觸(chu)體(ti)接地(di)(di)。無論環境如何(he)，電(dian)(dian)(dian)勢均為(wei)零，并且(qie)用(yong)電(dian)(dian)(dian)安(an)(an)全。因此，接地(di)(di)的(de)(de)主要(yao)作(zuo)用(yong)是保護(hu)人員和(he)(he)設(she)備的(de)(de)安(an)(an)全。
