箱體的主要設(she)備使用家用電(dian)(dian)器(qi)，例如真(zhen)空控制柜，干(gan)式變(bian)壓器(qi)，干(gan)式變(bian)壓器(qi)，真(zhen)空斷路器(qi)（彈簧操作機(ji)構），并且產品沒(mei)有裸露的帶電(dian)(dian)部件。它(ta)是全(quan)邊緣結構，可完全(quan)導致零電(dian)(dian)擊事(shi)故。整個站可以實現(xian)高度安全(quan)的無油運行。第二(er)次，集成到微計算(suan)機(ji)中的自(zi)動化系(xi)統用于實現(xian)無人值守的操作。

建(jian)議出(chu)于(yu)美觀原因，應(ying)使用鋼管敷(fu)設(she)10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜出(chu)口(kou)(kou)。變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)中的(de)10 kV箱式(shi)配電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)外殼(ke)通(tong)常用水泥鋪成(cheng)，并(bing)(bing)且10 kV線路(lu)終端通(tong)常在變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)壁外10 m。如(ru)果(guo)將電(dian)(dian)(dian)(dian)(dian)(dian)纜直(zhi)接埋在地下并(bing)(bing)引到電(dian)(dian)(dian)(dian)(dian)(dian)線桿上(shang)(shang)，則很難進行維護(hu)。因此，應(ying)將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜插座穿(chuan)過鋼管，以(yi)(yi)使用戶易于(yu)維護(hu)。如(ru)果(guo)10 kV線路(lu)的(de)連接極遠離變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)，則必須(xu)通(tong)過鋼管將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)出(chu)線口(kou)(kou)從機殼(ke)鋪設(she)到變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的(de)墻(qiang)壁。在電(dian)(dian)(dian)(dian)(dian)(dian)纜出(chu)口(kou)(kou)末端的(de)線路(lu)接線柱上(shang)(shang)安裝了新(xin)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)保護(hu)器，以(yi)(yi)避免過電(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(sheng)產廠家建(jian)議(yi)它還可(ke)(ke)以(yi)安(an)裝在35 kV設(she)備，10 kV設(she)備的(de)(de)室(shi)外(wai)以(yi)及控制和(he)保護系統(tong)箱(xiang)體。這(zhe)種組合(he)方法特別適用(yong)于將舊站點轉換為(wei)(wei)農村電(dian)(dian)網的(de)(de)轉換，即原始(shi)的(de)(de)35 kV設(she)備不(bu)動，僅安(an)裝10 kV配電(dian)(dian)箱(xiang)。可(ke)(ke)以(yi)滿足無人值守的(de)(de)要(yao)(yao)求。如果電(dian)(dian)氣設(she)備在運(yun)行過程中被接地阻塞，則電(dian)(dian)流將通過接地體流入地下。實驗(yan)表明，穿(chuan)過地球的(de)(de)電(dian)(dian)位為(wei)(wei)零，因此穿(chuan)過地球的(de)(de)電(dian)(dian)位為(wei)(wei)零。因此，在施加電(dian)(dian)能時要(yao)(yao)使用(yong)手動操(cao)作，以(yi)防止(zhi)所有接觸體接地。無論(lun)環境(jing)如何(he)，電(dian)(dian)勢均為(wei)(wei)零，并且用(yong)電(dian)(dian)安(an)全。因此，接地的(de)(de)主要(yao)(yao)作用(yong)是保護人員和(he)設(she)備的(de)(de)安(an)全。
