箱體的主要設備使用(yong)家用(yong)電(dian)(dian)器，例如真空控制柜，干(gan)式(shi)變壓器，干(gan)式(shi)變壓器，真空斷(duan)路器（彈簧操作(zuo)機(ji)構），并且產(chan)品(pin)沒有裸露的帶電(dian)(dian)部件。它是全(quan)(quan)邊緣結構，可(ke)完全(quan)(quan)導致零電(dian)(dian)擊事故。整(zheng)個站可(ke)以實現高度安全(quan)(quan)的無(wu)油(you)運行。第(di)二(er)次(ci)，集成到微(wei)計算機(ji)中的自動化系統用(yong)于實現無(wu)人值守(shou)的操作(zuo)。

建議出(chu)于(yu)美觀原因，應(ying)使用鋼(gang)管(guan)敷設(she)10 kV電(dian)(dian)(dian)纜出(chu)口。變電(dian)(dian)(dian)站(zhan)中(zhong)的10 kV箱式配(pei)電(dian)(dian)(dian)站(zhan)外殼通(tong)常用水(shui)泥鋪成，并(bing)且10 kV線路(lu)終端通(tong)常在(zai)變電(dian)(dian)(dian)站(zhan)壁外10 m。如果(guo)將電(dian)(dian)(dian)纜直接埋在(zai)地(di)下并(bing)引到電(dian)(dian)(dian)線桿(gan)上(shang)，則很難進行維(wei)護。因此，應(ying)將10 kV電(dian)(dian)(dian)纜插座穿過(guo)鋼(gang)管(guan)，以使用戶(hu)易于(yu)維(wei)護。如果(guo)10 kV線路(lu)的連接極遠(yuan)離變電(dian)(dian)(dian)站(zhan)，則必須通(tong)過(guo)鋼(gang)管(guan)將10 kV電(dian)(dian)(dian)纜的出(chu)線口從機殼鋪設(she)到變電(dian)(dian)(dian)站(zhan)的墻(qiang)壁。在(zai)電(dian)(dian)(dian)纜出(chu)口末(mo)端的線路(lu)接線柱(zhu)上(shang)安裝了新的電(dian)(dian)(dian)涌保護器，以避免過(guo)電(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。生產廠家建議它還可(ke)以安(an)(an)裝(zhuang)在(zai)35 kV設(she)(she)備，10 kV設(she)(she)備的(de)(de)室外(wai)以及控制和(he)保(bao)護系(xi)統箱體(ti)(ti)。這種組合方法特(te)別(bie)適用(yong)于將舊(jiu)站點轉換為(wei)農村電(dian)(dian)(dian)網(wang)的(de)(de)轉換，即原(yuan)始的(de)(de)35 kV設(she)(she)備不動，僅安(an)(an)裝(zhuang)10 kV配電(dian)(dian)(dian)箱。可(ke)以滿足(zu)無人值守的(de)(de)要(yao)求(qiu)。如果電(dian)(dian)(dian)氣設(she)(she)備在(zai)運行(xing)過程中被接(jie)地(di)(di)(di)阻塞，則電(dian)(dian)(dian)流(liu)(liu)將通過接(jie)地(di)(di)(di)體(ti)(ti)流(liu)(liu)入(ru)地(di)(di)(di)下。實驗表(biao)明，穿過地(di)(di)(di)球的(de)(de)電(dian)(dian)(dian)位(wei)為(wei)零，因(yin)(yin)此(ci)穿過地(di)(di)(di)球的(de)(de)電(dian)(dian)(dian)位(wei)為(wei)零。因(yin)(yin)此(ci)，在(zai)施加電(dian)(dian)(dian)能(neng)時要(yao)使用(yong)手動操作，以防止所有接(jie)觸體(ti)(ti)接(jie)地(di)(di)(di)。無論環境(jing)如何(he)，電(dian)(dian)(dian)勢均(jun)為(wei)零，并且用(yong)電(dian)(dian)(dian)安(an)(an)全。因(yin)(yin)此(ci)，接(jie)地(di)(di)(di)的(de)(de)主要(yao)作用(yong)是保(bao)護人員和(he)設(she)(she)備的(de)(de)安(an)(an)全。
