箱體的(de)主要(yao)設備使用(yong)家用(yong)電器(qi)，例如真空(kong)控制柜，干(gan)式(shi)(shi)變(bian)壓器(qi)，干(gan)式(shi)(shi)變(bian)壓器(qi)，真空(kong)斷(duan)路器(qi)（彈簧(huang)操(cao)作機構），并(bing)且產品沒有裸露的(de)帶(dai)電部件。它是全邊(bian)緣結構，可完全導(dao)致零(ling)電擊事故。整個(ge)站可以實現高度安全的(de)無油運行(xing)。第二次，集成到微計算機中(zhong)的(de)自動(dong)化系統(tong)用(yong)于(yu)實現無人值(zhi)守(shou)的(de)操(cao)作。

建議出(chu)于美觀原因(yin)，應使(shi)用鋼(gang)管(guan)敷設10 kV電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)口(kou)。變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站中的10 kV箱式配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站外殼通(tong)常用水泥鋪(pu)成(cheng)，并且10 kV線(xian)(xian)路終(zhong)端(duan)通(tong)常在(zai)(zai)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站壁外10 m。如(ru)(ru)果(guo)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)直接(jie)埋在(zai)(zai)地(di)下并引到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)桿(gan)上，則(ze)很難(nan)進行維護。因(yin)此(ci)，應將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)插座穿過(guo)鋼(gang)管(guan)，以使(shi)用戶易于維護。如(ru)(ru)果(guo)10 kV線(xian)(xian)路的連接(jie)極(ji)遠(yuan)離變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站，則(ze)必須通(tong)過(guo)鋼(gang)管(guan)將10 kV電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的出(chu)線(xian)(xian)口(kou)從機殼鋪(pu)設到變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站的墻壁。在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)出(chu)口(kou)末端(duan)的線(xian)(xian)路接(jie)線(xian)(xian)柱上安裝了(le)新(xin)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)涌保(bao)護器(qi)，以避免(mian)過(guo)電(dian)(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)產廠家(jia)建議它還可(ke)以(yi)(yi)安(an)裝(zhuang)在35 kV設(she)備，10 kV設(she)備的室外以(yi)(yi)及控制和保(bao)護系統箱體(ti)。這種組(zu)合方法特別適用于將(jiang)(jiang)舊站點轉(zhuan)換(huan)為農村電網的轉(zhuan)換(huan)，即原始的35 kV設(she)備不動，僅安(an)裝(zhuang)10 kV配電箱。可(ke)以(yi)(yi)滿足無人(ren)值守(shou)的要(yao)求。如果電氣(qi)設(she)備在運(yun)行過(guo)程中被接(jie)地(di)(di)阻塞，則(ze)電流將(jiang)(jiang)通過(guo)接(jie)地(di)(di)體(ti)流入地(di)(di)下。實驗(yan)表明(ming)，穿過(guo)地(di)(di)球(qiu)的電位為零(ling)，因(yin)此穿過(guo)地(di)(di)球(qiu)的電位為零(ling)。因(yin)此，在施加電能時要(yao)使用手動操作，以(yi)(yi)防止所有(you)接(jie)觸體(ti)接(jie)地(di)(di)。無論(lun)環境如何，電勢均為零(ling)，并(bing)且用電安(an)全。因(yin)此，接(jie)地(di)(di)的主要(yao)作用是保(bao)護人(ren)員(yuan)和設(she)備的安(an)全。
