根據的說法，將有用于大型電源系統的1級，2級和3級設備。通常，級主要是用于功率控制的配電中心，該配電中心通常安裝在變電站中，負責將電能分配到第二級。配電柜。第(di)二級配電(dian)(dian)柜(ju)(ju)(ju)必(bi)須懲罰(fa)級配電(dian)(dian)柜(ju)(ju)(ju)分配的(de)電(dian)(dian)能。第(di)三級配電(dian)(dian)柜(ju)(ju)(ju)是光通量配電(dian)(dian)柜(ju)(ju)(ju)。由于我們分散了(le)其布(bu)局，因此容量相對較(jiao)低。配電(dian)(dian)柜(ju)(ju)(ju)可以(yi)為(wei)我們的(de)生活提供安全保障，因此必(bi)須安裝配電(dian)(dian)柜(ju)(ju)(ju)，并根據(ju)情(qing)況將其隱藏在墻壁或其他地方。

安裝手車式高壓開關柜。安裝方法與固定式高壓開關柜的安裝方法基本相同，但區別在于要確保手推車的互換性。每個手推車型動觸頭必須設置一致，動觸頭和靜觸頭的中心必須均勻且緊密接觸，以確保互換性。配電柜廠家需要不定時的檢查二次回路的(de)插(cha)頭和輔助觸點是否可靠焊(han)接。電(dian)動或機械鎖(suo)定正(zheng)確，因此(ci)手(shou)推(tui)車無法在關(guan)(guan)閉(bi)位(wei)置拉(la)出。安全(quan)隔板易于打開(kai)和關(guan)(guan)閉(bi)，并且(qie)可以(yi)通過手(shou)推(tui)車進(jin)行伸縮。手(shou)車的(de)接地裝置應(ying)與高(gao)壓(ya)配(pei)電(dian)柜(ju)的(de)固定框架良好接觸。高(gao)低壓(ya)開(kai)關(guan)(guan)柜(ju)中(zhong)的(de)控(kong)制(zhi)電(dian)纜已牢固固定，不(bu)會(hui)影響手(shou)推(tui)車的(de)移動。

高(gao)(gao)-低(di)-高(gao)(gao)頻轉(zhuan)(zhuan)換(huan)器(qi)(qi)(qi)：應用上下(xia)方法在(zai)中(zhong)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)環(huan)(huan)境中(zhong)應用低(di)壓(ya)(ya)(ya)(ya)(ya)或通(tong)(tong)用驅動器(qi)(qi)(qi)。原理是使(shi)用降壓(ya)(ya)(ya)(ya)(ya)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)將電(dian)(dian)網(wang)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)降低(di)到(dao)低(di)壓(ya)(ya)(ya)(ya)(ya)逆變(bian)(bian)器(qi)(qi)(qi)的(de)標(biao)稱或允許電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)輸入范圍。通(tong)(tong)過對(dui)(dui)逆變(bian)(bian)器(qi)(qi)(qi)進(jin)(jin)行轉(zhuan)(zhuan)換(huan)，然(ran)后將其從升壓(ya)(ya)(ya)(ya)(ya)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)轉(zhuan)(zhuan)換(huan)為所需的(de)電(dian)(dian)動機，可(ke)以形成(cheng)頻率和幅度可(ke)變(bian)(bian)的(de)交流(liu)(liu)(liu)電(dian)(dian)源。電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級。如(ru)果(guo)運(yun)行中(zhong)的(de)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)有兩個(ge)(ge)或更(geng)多個(ge)(ge)接地故障，則(ze)在(zai)鐵芯的(de)工作(zuo)磁通(tong)(tong)周圍會形成(cheng)短(duan)路匝(za)。短(duan)路匝(za)會產生大的(de)渦流(liu)(liu)(liu)和循(xun)環(huan)(huan)電(dian)(dian)流(liu)(liu)(liu)，以加熱鐵芯，升高(gao)(gao)油(you)溫，使(shi)邊緣碳化(hua)，并產生可(ke)燃氣體(ti)，從而導致輕(qing)質氣體(ti)的(de)連續運(yun)動。如(ru)果(guo)接地不好，則(ze)循(xun)環(huan)(huan)可(ke)能是暫(zan)時的(de)，從而導致輪輞油(you)松(song)動并碳化(hua)。此(ci)時，應通(tong)(tong)過色(se)譜法對(dui)(dui)油(you)進(jin)(jin)行分析，以確定故障的(de)性質。
