箱(xiang)體的(de)(de)(de)主要設備使用(yong)家(jia)用(yong)電器(qi)(qi)，例如真(zhen)空控制(zhi)柜，干式(shi)變壓器(qi)(qi)，干式(shi)變壓器(qi)(qi)，真(zhen)空斷路器(qi)(qi)（彈簧操作機構），并且產品沒有裸露的(de)(de)(de)帶電部件。它是全(quan)邊緣結(jie)構，可(ke)完全(quan)導致零電擊事(shi)故(gu)。整個站可(ke)以(yi)實現高度安全(quan)的(de)(de)(de)無油運行。第二次，集成到微計算機中的(de)(de)(de)自動化系統用(yong)于實現無人(ren)值守的(de)(de)(de)操作。

建(jian)議(yi)出(chu)于(yu)美(mei)觀原因，應使(shi)用鋼(gang)管敷設(she)10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)出(chu)口。變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)中的(de)(de)10 kV箱(xiang)式配電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)外殼通(tong)常用水泥(ni)鋪成，并(bing)且10 kV線路終(zhong)端通(tong)常在(zai)變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)壁外10 m。如果將電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)直(zhi)接埋在(zai)地(di)下并(bing)引(yin)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)線桿(gan)上，則很(hen)難進行維(wei)(wei)護。因此，應將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)插座穿(chuan)過(guo)鋼(gang)管，以使(shi)用戶易于(yu)維(wei)(wei)護。如果10 kV線路的(de)(de)連(lian)接極遠離變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)，則必須通(tong)過(guo)鋼(gang)管將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)出(chu)線口從機殼鋪設(she)到(dao)變電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)墻壁。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)出(chu)口末端的(de)(de)線路接線柱上安裝了新的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)涌保護器，以避免過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。

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)廠家(jia)建議它還可以(yi)安裝在(zai)(zai)35 kV設(she)備，10 kV設(she)備的(de)室外以(yi)及控制和保護系統箱(xiang)體。這(zhe)種組合方法特別適(shi)用(yong)于將(jiang)舊站(zhan)點(dian)轉換為農村電(dian)(dian)(dian)網的(de)轉換，即原始的(de)35 kV設(she)備不動，僅安裝10 kV配電(dian)(dian)(dian)箱(xiang)。可以(yi)滿足(zu)無人值守的(de)要求。如(ru)果電(dian)(dian)(dian)氣設(she)備在(zai)(zai)運行過程中(zhong)被接(jie)地(di)(di)阻(zu)塞(sai)，則電(dian)(dian)(dian)流將(jiang)通過接(jie)地(di)(di)體流入地(di)(di)下。實驗表明(ming)，穿(chuan)過地(di)(di)球(qiu)的(de)電(dian)(dian)(dian)位為零，因(yin)此穿(chuan)過地(di)(di)球(qiu)的(de)電(dian)(dian)(dian)位為零。因(yin)此，在(zai)(zai)施加電(dian)(dian)(dian)能時要使用(yong)手動操作(zuo)，以(yi)防(fang)止所有接(jie)觸體接(jie)地(di)(di)。無論(lun)環境如(ru)何，電(dian)(dian)(dian)勢(shi)均為零，并且用(yong)電(dian)(dian)(dian)安全。因(yin)此，接(jie)地(di)(di)的(de)主要作(zuo)用(yong)是保護人員(yuan)和設(she)備的(de)安全。
