箱體的(de)(de)主要設備使用(yong)家(jia)用(yong)電器(qi)(qi)，例如真空(kong)控制柜，干式(shi)(shi)變壓(ya)(ya)器(qi)(qi)，干式(shi)(shi)變壓(ya)(ya)器(qi)(qi)，真空(kong)斷路(lu)器(qi)(qi)（彈(dan)簧操(cao)作機構(gou)），并且產(chan)品(pin)沒有(you)裸露的(de)(de)帶電部件。它是(shi)全(quan)邊緣結(jie)構(gou)，可完全(quan)導(dao)致零電擊事故。整個(ge)站可以實(shi)現(xian)高度安(an)全(quan)的(de)(de)無(wu)油運行。第二次(ci)，集(ji)成(cheng)到微計算機中的(de)(de)自動化系(xi)統用(yong)于實(shi)現(xian)無(wu)人值守(shou)的(de)(de)操(cao)作。

建議出(chu)(chu)于美(mei)觀原(yuan)因，應(ying)使用鋼管(guan)(guan)敷(fu)設10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜出(chu)(chu)口。變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)中的(de)(de)10 kV箱式配電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)外殼(ke)通(tong)常用水泥鋪(pu)成，并(bing)且10 kV線(xian)路終端(duan)通(tong)常在變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)壁外10 m。如(ru)果將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)纜直(zhi)接(jie)埋在地下并(bing)引到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)桿上，則很難進行維護。因此，應(ying)將(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜插座穿過(guo)鋼管(guan)(guan)，以(yi)使用戶易于維護。如(ru)果10 kV線(xian)路的(de)(de)連接(jie)極遠離(li)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)，則必須通(tong)過(guo)鋼管(guan)(guan)將(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)出(chu)(chu)線(xian)口從機(ji)殼(ke)鋪(pu)設到(dao)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)墻壁。在電(dian)(dian)(dian)(dian)(dian)(dian)纜出(chu)(chu)口末端(duan)的(de)(de)線(xian)路接(jie)線(xian)柱上安裝了新的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)涌保護器，以(yi)避(bi)免過(guo)電(dian)(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(jia)建議它還可以(yi)(yi)安(an)裝在(zai)35 kV設備，10 kV設備的(de)(de)室外以(yi)(yi)及(ji)控制和保護系(xi)統箱體(ti)(ti)。這種組合方法特別適用(yong)于將舊站點(dian)轉(zhuan)換(huan)為(wei)農村電(dian)網的(de)(de)轉(zhuan)換(huan)，即原始的(de)(de)35 kV設備不動，僅安(an)裝10 kV配電(dian)箱。可以(yi)(yi)滿足無(wu)人值守(shou)的(de)(de)要求。如果電(dian)氣設備在(zai)運行過(guo)(guo)程中被(bei)接地阻(zu)塞，則電(dian)流將通過(guo)(guo)接地體(ti)(ti)流入地下。實(shi)驗表明，穿(chuan)過(guo)(guo)地球(qiu)的(de)(de)電(dian)位為(wei)零，因此穿(chuan)過(guo)(guo)地球(qiu)的(de)(de)電(dian)位為(wei)零。因此，在(zai)施加(jia)電(dian)能時(shi)要使用(yong)手(shou)動操作(zuo)，以(yi)(yi)防止所(suo)有(you)接觸體(ti)(ti)接地。無(wu)論環境(jing)如何，電(dian)勢(shi)均為(wei)零，并且用(yong)電(dian)安(an)全(quan)。因此，接地的(de)(de)主要作(zuo)用(yong)是保護人員(yuan)和設備的(de)(de)安(an)全(quan)。
