箱體的(de)主(zhu)要設備使(shi)用(yong)家用(yong)電(dian)器，例(li)如真(zhen)空控制柜(ju)，干式變(bian)壓(ya)器，干式變(bian)壓(ya)器，真(zhen)空斷路器（彈簧(huang)操作機構(gou)），并且產(chan)品沒有裸(luo)露的(de)帶(dai)電(dian)部件。它是全(quan)邊緣結構(gou)，可完全(quan)導致(zhi)零電(dian)擊事(shi)故。整個站可以實現高度(du)安全(quan)的(de)無油運行。第(di)二次，集成到(dao)微(wei)計(ji)算機中的(de)自動(dong)化(hua)系(xi)統用(yong)于實現無人值(zhi)守的(de)操作。

建議出(chu)于(yu)美(mei)觀(guan)原因，應使用鋼管敷設10 kV電(dian)(dian)(dian)纜(lan)出(chu)口(kou)。變(bian)(bian)電(dian)(dian)(dian)站(zhan)中的(de)10 kV箱式(shi)配電(dian)(dian)(dian)站(zhan)外殼(ke)通(tong)(tong)(tong)常用水泥(ni)鋪(pu)成，并(bing)且10 kV線(xian)路(lu)終端通(tong)(tong)(tong)常在(zai)變(bian)(bian)電(dian)(dian)(dian)站(zhan)壁外10 m。如(ru)果(guo)(guo)將(jiang)電(dian)(dian)(dian)纜(lan)直(zhi)接(jie)埋在(zai)地(di)下(xia)并(bing)引到電(dian)(dian)(dian)線(xian)桿上(shang)(shang)，則很(hen)難進行維護。因此，應將(jiang)10 kV電(dian)(dian)(dian)纜(lan)插座穿(chuan)過(guo)鋼管，以(yi)使用戶易于(yu)維護。如(ru)果(guo)(guo)10 kV線(xian)路(lu)的(de)連(lian)接(jie)極(ji)遠(yuan)離變(bian)(bian)電(dian)(dian)(dian)站(zhan)，則必(bi)須通(tong)(tong)(tong)過(guo)鋼管將(jiang)10 kV電(dian)(dian)(dian)纜(lan)的(de)出(chu)線(xian)口(kou)從機(ji)殼(ke)鋪(pu)設到變(bian)(bian)電(dian)(dian)(dian)站(zhan)的(de)墻壁。在(zai)電(dian)(dian)(dian)纜(lan)出(chu)口(kou)末端的(de)線(xian)路(lu)接(jie)線(xian)柱(zhu)上(shang)(shang)安裝了新的(de)電(dian)(dian)(dian)涌保護器，以(yi)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以安裝在35 kV設(she)(she)(she)(she)備，10 kV設(she)(she)(she)(she)備的(de)室(shi)外(wai)以及控(kong)制(zhi)和(he)保護系統箱體(ti)。這(zhe)種組合方(fang)法特別適用于(yu)將(jiang)舊(jiu)站(zhan)點轉換為農(nong)村電(dian)(dian)(dian)(dian)(dian)網的(de)轉換，即原始的(de)35 kV設(she)(she)(she)(she)備不動(dong)，僅安裝10 kV配電(dian)(dian)(dian)(dian)(dian)箱。可以滿(man)足無人值守(shou)的(de)要(yao)(yao)求。如果電(dian)(dian)(dian)(dian)(dian)氣設(she)(she)(she)(she)備在運行過(guo)程中被接地(di)(di)阻塞，則電(dian)(dian)(dian)(dian)(dian)流將(jiang)通過(guo)接地(di)(di)體(ti)流入地(di)(di)下。實驗表(biao)明，穿過(guo)地(di)(di)球(qiu)(qiu)的(de)電(dian)(dian)(dian)(dian)(dian)位為零(ling)，因(yin)此(ci)穿過(guo)地(di)(di)球(qiu)(qiu)的(de)電(dian)(dian)(dian)(dian)(dian)位為零(ling)。因(yin)此(ci)，在施(shi)加電(dian)(dian)(dian)(dian)(dian)能時要(yao)(yao)使用手動(dong)操作(zuo)，以防止所(suo)有(you)接觸體(ti)接地(di)(di)。無論環境如何，電(dian)(dian)(dian)(dian)(dian)勢均為零(ling)，并且用電(dian)(dian)(dian)(dian)(dian)安全(quan)。因(yin)此(ci)，接地(di)(di)的(de)主要(yao)(yao)作(zuo)用是(shi)保護人員和(he)設(she)(she)(she)(she)備的(de)安全(quan)。
