箱體的主要設備使用(yong)家用(yong)電(dian)器，例如真空控制柜，干式(shi)變(bian)壓(ya)(ya)器，干式(shi)變(bian)壓(ya)(ya)器，真空斷路器（彈(dan)簧操作機構(gou)），并(bing)且產(chan)品沒有裸露的帶電(dian)部件。它是全邊(bian)緣結構(gou)，可完全導致零電(dian)擊事故。整個站可以實(shi)現高(gao)度安(an)全的無油運行。第二次，集成(cheng)到(dao)微計(ji)算機中的自(zi)動化系統用(yong)于實(shi)現無人值守的操作。

建議(yi)出(chu)于美(mei)觀原因，應(ying)使用鋼管敷設(she)10 kV電(dian)(dian)(dian)(dian)(dian)纜出(chu)口。變電(dian)(dian)(dian)(dian)(dian)站中的(de)(de)10 kV箱式(shi)配(pei)電(dian)(dian)(dian)(dian)(dian)站外(wai)殼(ke)通常(chang)用水泥鋪成，并且10 kV線(xian)路(lu)終端通常(chang)在變電(dian)(dian)(dian)(dian)(dian)站壁外(wai)10 m。如(ru)(ru)果將(jiang)電(dian)(dian)(dian)(dian)(dian)纜直接埋(mai)在地下并引到(dao)電(dian)(dian)(dian)(dian)(dian)線(xian)桿上(shang)，則很(hen)難進(jin)行維護。因此，應(ying)將(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)纜插座穿過(guo)鋼管，以(yi)使用戶易(yi)于維護。如(ru)(ru)果10 kV線(xian)路(lu)的(de)(de)連接極遠離變電(dian)(dian)(dian)(dian)(dian)站，則必須通過(guo)鋼管將(jiang)10 kV電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)出(chu)線(xian)口從(cong)機殼(ke)鋪設(she)到(dao)變電(dian)(dian)(dian)(dian)(dian)站的(de)(de)墻(qiang)壁。在電(dian)(dian)(dian)(dian)(dian)纜出(chu)口末(mo)端的(de)(de)線(xian)路(lu)接線(xian)柱上(shang)安裝了新的(de)(de)電(dian)(dian)(dian)(dian)(dian)涌保護器，以(yi)避免(mian)過(guo)電(dian)(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(ke)以安(an)裝在35 kV設(she)(she)備，10 kV設(she)(she)備的室外以及控制和保護(hu)(hu)系統箱體(ti)。這(zhe)種組合(he)方法特別適(shi)用(yong)于將(jiang)舊站點轉換(huan)為農村(cun)電(dian)(dian)網(wang)的轉換(huan)，即(ji)原始的35 kV設(she)(she)備不動，僅安(an)裝10 kV配電(dian)(dian)箱。可(ke)以滿足無人(ren)值守的要(yao)求。如果電(dian)(dian)氣設(she)(she)備在運行(xing)過(guo)程中被(bei)接(jie)(jie)(jie)地(di)阻塞(sai)，則電(dian)(dian)流將(jiang)通過(guo)接(jie)(jie)(jie)地(di)體(ti)流入地(di)下。實驗表(biao)明，穿(chuan)過(guo)地(di)球的電(dian)(dian)位為零(ling)，因此(ci)穿(chuan)過(guo)地(di)球的電(dian)(dian)位為零(ling)。因此(ci)，在施加電(dian)(dian)能時要(yao)使用(yong)手動操作，以防止所有接(jie)(jie)(jie)觸體(ti)接(jie)(jie)(jie)地(di)。無論環境如何，電(dian)(dian)勢均(jun)為零(ling)，并且用(yong)電(dian)(dian)安(an)全。因此(ci)，接(jie)(jie)(jie)地(di)的主要(yao)作用(yong)是保護(hu)(hu)人(ren)員(yuan)和設(she)(she)備的安(an)全。
