箱體的(de)主(zhu)要設備使(shi)用(yong)(yong)家用(yong)(yong)電(dian)器(qi)，例如真空控制柜，干式(shi)變壓器(qi)，干式(shi)變壓器(qi)，真空斷路器(qi)（彈簧操作(zuo)機(ji)構），并且(qie)產品沒有(you)裸露的(de)帶電(dian)部件。它是全(quan)(quan)邊緣結構，可(ke)完全(quan)(quan)導致零電(dian)擊(ji)事故。整(zheng)個站可(ke)以實(shi)現(xian)高(gao)度安全(quan)(quan)的(de)無油運行。第二次，集成到(dao)微計算機(ji)中的(de)自動化(hua)系統用(yong)(yong)于實(shi)現(xian)無人值守的(de)操作(zuo)。

建議出于美觀(guan)原(yuan)因，應使(shi)用鋼管敷(fu)設(she)10 kV電(dian)(dian)(dian)(dian)纜(lan)出口(kou)。變電(dian)(dian)(dian)(dian)站(zhan)(zhan)中的(de)(de)(de)10 kV箱式(shi)配電(dian)(dian)(dian)(dian)站(zhan)(zhan)外殼通常用水(shui)泥鋪成，并且(qie)10 kV線(xian)(xian)(xian)路(lu)終端(duan)(duan)通常在變電(dian)(dian)(dian)(dian)站(zhan)(zhan)壁外10 m。如(ru)果將(jiang)(jiang)電(dian)(dian)(dian)(dian)纜(lan)直接(jie)埋在地(di)下(xia)并引(yin)到電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)桿(gan)上(shang)，則很難(nan)進行(xing)維護(hu)。因此，應將(jiang)(jiang)10 kV電(dian)(dian)(dian)(dian)纜(lan)插座(zuo)穿過鋼管，以使(shi)用戶易(yi)于維護(hu)。如(ru)果10 kV線(xian)(xian)(xian)路(lu)的(de)(de)(de)連接(jie)極(ji)遠離變電(dian)(dian)(dian)(dian)站(zhan)(zhan)，則必須通過鋼管將(jiang)(jiang)10 kV電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)出線(xian)(xian)(xian)口(kou)從機殼鋪設(she)到變電(dian)(dian)(dian)(dian)站(zhan)(zhan)的(de)(de)(de)墻壁。在電(dian)(dian)(dian)(dian)纜(lan)出口(kou)末端(duan)(duan)的(de)(de)(de)線(xian)(xian)(xian)路(lu)接(jie)線(xian)(xian)(xian)柱上(shang)安裝了新的(de)(de)(de)電(dian)(dian)(dian)(dian)涌保護(hu)器，以避免過電(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。生產廠(chang)家建議它還可以(yi)安(an)(an)裝(zhuang)在(zai)35 kV設(she)備，10 kV設(she)備的(de)(de)(de)室(shi)外以(yi)及控制和保(bao)護系統箱(xiang)(xiang)體。這種組(zu)合(he)方法特別適用于將舊站點轉換為農村(cun)電(dian)(dian)(dian)(dian)網的(de)(de)(de)轉換，即原(yuan)始的(de)(de)(de)35 kV設(she)備不動，僅安(an)(an)裝(zhuang)10 kV配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)。可以(yi)滿足無人值守的(de)(de)(de)要(yao)求。如(ru)果(guo)電(dian)(dian)(dian)(dian)氣設(she)備在(zai)運行過(guo)程中被接地(di)(di)(di)阻塞，則(ze)電(dian)(dian)(dian)(dian)流(liu)將通過(guo)接地(di)(di)(di)體流(liu)入地(di)(di)(di)下。實(shi)驗表明(ming)，穿過(guo)地(di)(di)(di)球的(de)(de)(de)電(dian)(dian)(dian)(dian)位為零，因(yin)(yin)此穿過(guo)地(di)(di)(di)球的(de)(de)(de)電(dian)(dian)(dian)(dian)位為零。因(yin)(yin)此，在(zai)施加電(dian)(dian)(dian)(dian)能時(shi)要(yao)使用手動操作(zuo)，以(yi)防止所有接觸(chu)體接地(di)(di)(di)。無論環境如(ru)何，電(dian)(dian)(dian)(dian)勢(shi)均為零，并且(qie)用電(dian)(dian)(dian)(dian)安(an)(an)全(quan)。因(yin)(yin)此，接地(di)(di)(di)的(de)(de)(de)主要(yao)作(zuo)用是保(bao)護人員(yuan)和設(she)備的(de)(de)(de)安(an)(an)全(quan)。
