箱體(ti)的(de)主要(yao)設(she)備使用(yong)(yong)(yong)家用(yong)(yong)(yong)電(dian)器(qi)(qi)，例如(ru)真空(kong)控制柜(ju)，干式變壓器(qi)(qi)，干式變壓器(qi)(qi)，真空(kong)斷路(lu)器(qi)(qi)（彈簧操(cao)作機(ji)構），并且產品沒有裸露的(de)帶電(dian)部件。它是全(quan)邊緣(yuan)結構，可完全(quan)導(dao)致(zhi)零電(dian)擊事(shi)故。整個(ge)站可以(yi)實現高度(du)安全(quan)的(de)無(wu)油運行。第二(er)次，集成到微(wei)計算機(ji)中的(de)自動(dong)化系(xi)統用(yong)(yong)(yong)于實現無(wu)人值守的(de)操(cao)作。

建議(yi)出(chu)于美觀原因，應使用鋼(gang)管敷設10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)出(chu)口。變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)中的(de)(de)10 kV箱(xiang)式配(pei)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)外(wai)殼(ke)通常用水泥鋪成，并且(qie)10 kV線(xian)(xian)(xian)路(lu)終(zhong)端通常在變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)壁外(wai)10 m。如(ru)果(guo)將(jiang)(jiang)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)直接(jie)(jie)埋在地下并引到電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)桿上，則很難進行維(wei)(wei)護(hu)。因此，應將(jiang)(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)插座穿過鋼(gang)管，以使用戶易于維(wei)(wei)護(hu)。如(ru)果(guo)10 kV線(xian)(xian)(xian)路(lu)的(de)(de)連接(jie)(jie)極遠離變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，則必須通過鋼(gang)管將(jiang)(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)出(chu)線(xian)(xian)(xian)口從(cong)機(ji)殼(ke)鋪設到變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)(de)墻壁。在電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)出(chu)口末(mo)端的(de)(de)線(xian)(xian)(xian)路(lu)接(jie)(jie)線(xian)(xian)(xian)柱上安裝了新的(de)(de)電(dian)(dian)(dian)(dian)(dian)涌保護(hu)器，以避(bi)免過電(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。生產(chan)廠(chang)家建議它還可以(yi)安(an)(an)裝在35 kV設(she)備(bei)，10 kV設(she)備(bei)的室外以(yi)及控制(zhi)和保護(hu)系(xi)統箱體。這種組(zu)合(he)方法特別適用(yong)于將舊站點轉(zhuan)換為(wei)農村電網的轉(zhuan)換，即(ji)原始(shi)的35 kV設(she)備(bei)不動，僅安(an)(an)裝10 kV配電箱。可以(yi)滿(man)足(zu)無人值(zhi)守的要(yao)求。如果電氣設(she)備(bei)在運行過(guo)程中被(bei)接地(di)(di)阻塞，則電流(liu)將通(tong)過(guo)接地(di)(di)體流(liu)入地(di)(di)下。實(shi)驗表明，穿過(guo)地(di)(di)球(qiu)的電位為(wei)零，因此穿過(guo)地(di)(di)球(qiu)的電位為(wei)零。因此，在施加(jia)電能時要(yao)使用(yong)手動操作，以(yi)防止所有接觸(chu)體接地(di)(di)。無論(lun)環境(jing)如何(he)，電勢均為(wei)零，并且用(yong)電安(an)(an)全。因此，接地(di)(di)的主(zhu)要(yao)作用(yong)是保護(hu)人員(yuan)和設(she)備(bei)的安(an)(an)全。
