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(pei)電(dian)(dian)柜(ju)(ju)(ju)必(bi)須懲罰級配(pei)電(dian)(dian)柜(ju)(ju)(ju)分配(pei)的電(dian)(dian)能。第(di)三級配(pei)電(dian)(dian)柜(ju)(ju)(ju)是光通量(liang)配(pei)電(dian)(dian)柜(ju)(ju)(ju)。由(you)于我(wo)們分散了其(qi)布局，因(yin)此(ci)容量(liang)相對較低。配(pei)電(dian)(dian)柜(ju)(ju)(ju)可以(yi)為我(wo)們的生(sheng)活提供安(an)全保障，因(yin)此(ci)必(bi)須安(an)裝配(pei)電(dian)(dian)柜(ju)(ju)(ju)，并根據情況將其(qi)隱藏在墻(qiang)壁(bi)或其(qi)他地(di)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(ci)回路的插頭和(he)輔助觸點是否(fou)可靠焊接(jie)。電動或機械鎖定(ding)正(zheng)確，因此手(shou)推(tui)(tui)車無(wu)法在關(guan)閉(bi)位置拉出(chu)。安全(quan)隔(ge)板易于(yu)打開(kai)和(he)關(guan)閉(bi)，并且可以通過(guo)手(shou)推(tui)(tui)車進行伸縮。手(shou)車的接(jie)地裝置應與高(gao)壓(ya)配(pei)電柜(ju)的固定(ding)框架良好接(jie)觸。高(gao)低壓(ya)開(kai)關(guan)柜(ju)中的控制電纜(lan)已牢固固定(ding)，不會(hui)影響手(shou)推(tui)(tui)車的移(yi)動。

高-低(di)(di)-高頻(pin)(pin)轉(zhuan)換(huan)器(qi)(qi)：應(ying)用(yong)上(shang)下(xia)方法在(zai)中(zhong)(zhong)高壓(ya)(ya)(ya)(ya)環(huan)境中(zhong)(zhong)應(ying)用(yong)低(di)(di)壓(ya)(ya)(ya)(ya)或通(tong)(tong)用(yong)驅動器(qi)(qi)。原理是(shi)使(shi)用(yong)降壓(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)器(qi)(qi)將電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)降低(di)(di)到低(di)(di)壓(ya)(ya)(ya)(ya)逆(ni)變器(qi)(qi)的(de)(de)標稱或允許(xu)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)輸入(ru)范圍(wei)。通(tong)(tong)過(guo)對(dui)逆(ni)變器(qi)(qi)進行(xing)轉(zhuan)換(huan)，然后將其從(cong)(cong)升壓(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)器(qi)(qi)轉(zhuan)換(huan)為(wei)所需(xu)的(de)(de)電(dian)(dian)(dian)動機，可以(yi)(yi)形(xing)(xing)成頻(pin)(pin)率(lv)和幅度(du)可變的(de)(de)交流電(dian)(dian)(dian)源。電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)等級。如(ru)果(guo)(guo)運行(xing)中(zhong)(zhong)的(de)(de)變壓(ya)(ya)(ya)(ya)器(qi)(qi)有兩(liang)個或更多個接地故障，則(ze)在(zai)鐵(tie)(tie)芯(xin)的(de)(de)工作磁通(tong)(tong)周圍(wei)會形(xing)(xing)成短(duan)(duan)路(lu)(lu)匝(za)。短(duan)(duan)路(lu)(lu)匝(za)會產生(sheng)大的(de)(de)渦流和循環(huan)電(dian)(dian)(dian)流，以(yi)(yi)加熱鐵(tie)(tie)芯(xin)，升高油溫，使(shi)邊緣碳(tan)化，并產生(sheng)可燃氣體，從(cong)(cong)而(er)導(dao)致(zhi)輕質氣體的(de)(de)連續運動。如(ru)果(guo)(guo)接地不好，則(ze)循環(huan)可能(neng)是(shi)暫時(shi)的(de)(de)，從(cong)(cong)而(er)導(dao)致(zhi)輪輞油松動并碳(tan)化。此時(shi)，應(ying)通(tong)(tong)過(guo)色譜法對(dui)油進行(xing)分析(xi)，以(yi)(yi)確定(ding)故障的(de)(de)性質。
