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。第二級(ji)配電(dian)(dian)柜必(bi)(bi)須(xu)懲罰級(ji)配電(dian)(dian)柜分(fen)配的(de)電(dian)(dian)能。第三級(ji)配電(dian)(dian)柜是(shi)光通量配電(dian)(dian)柜。由于(yu)我們(men)分(fen)散了其(qi)布(bu)局(ju)，因此(ci)容量相(xiang)對較低。配電(dian)(dian)柜可以為(wei)我們(men)的(de)生活(huo)提供安(an)全保障，因此(ci)必(bi)(bi)須(xu)安(an)裝(zhuang)配電(dian)(dian)柜，并根據情況將其(qi)隱(yin)藏在墻壁或(huo)其(qi)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(ci)回(hui)路的插頭和輔助(zhu)觸(chu)點是否可靠焊(han)接。電(dian)動(dong)或機械(xie)鎖定(ding)正確，因(yin)此手(shou)(shou)推(tui)車無法在(zai)關閉位置拉(la)出。安全隔板易于打開和關閉，并且可以通過手(shou)(shou)推(tui)車進(jin)行(xing)伸縮。手(shou)(shou)車的接地裝置應與高壓配(pei)電(dian)柜的固定(ding)框架良(liang)好接觸(chu)。高低壓開關柜中(zhong)的控制電(dian)纜已牢固固定(ding)，不(bu)會影響手(shou)(shou)推(tui)車的移動(dong)。

高-低-高頻(pin)轉(zhuan)(zhuan)換器(qi)(qi)(qi)：應用(yong)上下方法在中(zhong)(zhong)高壓(ya)(ya)(ya)(ya)(ya)環(huan)境(jing)中(zhong)(zhong)應用(yong)低壓(ya)(ya)(ya)(ya)(ya)或通(tong)(tong)用(yong)驅動(dong)器(qi)(qi)(qi)。原理(li)是(shi)使用(yong)降壓(ya)(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)將電(dian)(dian)網電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)降低到低壓(ya)(ya)(ya)(ya)(ya)逆變器(qi)(qi)(qi)的(de)標稱(cheng)或允許(xu)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)輸入范圍。通(tong)(tong)過對(dui)逆變器(qi)(qi)(qi)進行轉(zhuan)(zhuan)換，然后將其(qi)從(cong)(cong)升(sheng)壓(ya)(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)轉(zhuan)(zhuan)換為所需(xu)的(de)電(dian)(dian)動(dong)機，可(ke)以形成頻(pin)率(lv)和幅度可(ke)變的(de)交(jiao)流電(dian)(dian)源(yuan)。電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級。如果(guo)運(yun)行中(zhong)(zhong)的(de)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)有(you)兩(liang)個或更多個接地故障，則(ze)在鐵芯的(de)工作(zuo)磁通(tong)(tong)周圍會形成短路匝。短路匝會產(chan)生大的(de)渦流和循(xun)環(huan)電(dian)(dian)流，以加熱鐵芯，升(sheng)高油(you)溫，使邊緣碳化，并產(chan)生可(ke)燃氣體，從(cong)(cong)而導致輕(qing)質(zhi)氣體的(de)連續運(yun)動(dong)。如果(guo)接地不好，則(ze)循(xun)環(huan)可(ke)能(neng)是(shi)暫時的(de)，從(cong)(cong)而導致輪輞油(you)松動(dong)并碳化。此時，應通(tong)(tong)過色譜法對(dui)油(you)進行分析，以確(que)定故障的(de)性(xing)質(zhi)。
