箱體的(de)主要設(she)備使用(yong)家用(yong)電(dian)器，例如真空控制柜，干式(shi)變壓(ya)器，干式(shi)變壓(ya)器，真空斷路器（彈(dan)簧(huang)操(cao)作(zuo)機構），并且產品(pin)沒有裸(luo)露的(de)帶電(dian)部件。它是(shi)全(quan)邊緣結構，可完全(quan)導致(zhi)零(ling)電(dian)擊(ji)事故。整個站可以(yi)實現高度安全(quan)的(de)無(wu)油(you)運(yun)行(xing)。第二次，集成到微計(ji)算機中(zhong)的(de)自(zi)動化系統用(yong)于(yu)實現無(wu)人值守的(de)操(cao)作(zuo)。

建議(yi)出(chu)于美(mei)觀原(yuan)因(yin)(yin)，應使用鋼(gang)管(guan)敷設10 kV電(dian)(dian)纜(lan)(lan)出(chu)口。變(bian)(bian)電(dian)(dian)站(zhan)(zhan)中(zhong)的(de)10 kV箱式配電(dian)(dian)站(zhan)(zhan)外殼(ke)通(tong)(tong)(tong)常用水泥鋪成，并且10 kV線(xian)路終端通(tong)(tong)(tong)常在(zai)變(bian)(bian)電(dian)(dian)站(zhan)(zhan)壁外10 m。如(ru)果將電(dian)(dian)纜(lan)(lan)直接(jie)埋在(zai)地(di)下并引到(dao)電(dian)(dian)線(xian)桿上(shang)(shang)，則很(hen)難進行維(wei)護(hu)。因(yin)(yin)此(ci)，應將10 kV電(dian)(dian)纜(lan)(lan)插座穿過(guo)鋼(gang)管(guan)，以使用戶易于維(wei)護(hu)。如(ru)果10 kV線(xian)路的(de)連接(jie)極遠離(li)變(bian)(bian)電(dian)(dian)站(zhan)(zhan)，則必(bi)須通(tong)(tong)(tong)過(guo)鋼(gang)管(guan)將10 kV電(dian)(dian)纜(lan)(lan)的(de)出(chu)線(xian)口從機殼(ke)鋪設到(dao)變(bian)(bian)電(dian)(dian)站(zhan)(zhan)的(de)墻(qiang)壁。在(zai)電(dian)(dian)纜(lan)(lan)出(chu)口末(mo)端的(de)線(xian)路接(jie)線(xian)柱上(shang)(shang)安裝(zhuang)了新的(de)電(dian)(dian)涌保護(hu)器，以避免(mian)過(guo)電(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(chan)廠家建議它還(huan)可(ke)以安(an)裝在35 kV設(she)備(bei)，10 kV設(she)備(bei)的(de)(de)室(shi)外以及控制和(he)保護(hu)系統箱(xiang)體(ti)。這種(zhong)組合方法(fa)特(te)別適(shi)用(yong)于將(jiang)舊站點(dian)轉換為農村電(dian)(dian)(dian)(dian)(dian)(dian)網的(de)(de)轉換，即原始(shi)的(de)(de)35 kV設(she)備(bei)不動，僅安(an)裝10 kV配電(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)。可(ke)以滿足無(wu)人(ren)值守的(de)(de)要求。如果電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設(she)備(bei)在運(yun)行過(guo)程(cheng)中被接地阻(zu)塞，則電(dian)(dian)(dian)(dian)(dian)(dian)流將(jiang)通過(guo)接地體(ti)流入地下。實驗表明，穿(chuan)過(guo)地球的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)位(wei)為零(ling)(ling)，因(yin)(yin)此穿(chuan)過(guo)地球的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)位(wei)為零(ling)(ling)。因(yin)(yin)此，在施加(jia)電(dian)(dian)(dian)(dian)(dian)(dian)能時要使用(yong)手動操作，以防止所有接觸體(ti)接地。無(wu)論環(huan)境如何，電(dian)(dian)(dian)(dian)(dian)(dian)勢均為零(ling)(ling)，并(bing)且用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)安(an)全。因(yin)(yin)此，接地的(de)(de)主要作用(yong)是保護(hu)人(ren)員和(he)設(she)備(bei)的(de)(de)安(an)全。
