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(ji)配(pei)電(dian)(dian)(dian)(dian)柜(ju)必須懲罰級(ji)配(pei)電(dian)(dian)(dian)(dian)柜(ju)分(fen)配(pei)的電(dian)(dian)(dian)(dian)能。第(di)三級(ji)配(pei)電(dian)(dian)(dian)(dian)柜(ju)是光通量配(pei)電(dian)(dian)(dian)(dian)柜(ju)。由于我們(men)分(fen)散了其(qi)布局，因(yin)此容(rong)量相對較低。配(pei)電(dian)(dian)(dian)(dian)柜(ju)可(ke)以為我們(men)的生活提(ti)供安全(quan)保障，因(yin)此必須安裝配(pei)電(dian)(dian)(dian)(dian)柜(ju)，并根(gen)據情況將其(qi)隱(yin)藏在墻(qiang)壁或其(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(er)次回路的插頭和輔助觸點是否可靠焊接(jie)。電(dian)動或機械鎖(suo)定正確，因(yin)此手(shou)推(tui)車(che)無法在(zai)關閉位置拉出(chu)。安全(quan)隔板易于打(da)開和關閉，并且可以通過手(shou)推(tui)車(che)進行伸縮。手(shou)車(che)的接(jie)地裝置應與高壓配電(dian)柜的固(gu)定框架良好接(jie)觸。高低壓開關柜中(zhong)的控(kong)制電(dian)纜已牢(lao)固(gu)固(gu)定，不會影響手(shou)推(tui)車(che)的移動。

高(gao)(gao)-低-高(gao)(gao)頻轉(zhuan)換(huan)(huan)器(qi)(qi)(qi)(qi)：應(ying)用(yong)上(shang)下方法(fa)(fa)在中(zhong)(zhong)高(gao)(gao)壓(ya)(ya)(ya)環(huan)(huan)境中(zhong)(zhong)應(ying)用(yong)低壓(ya)(ya)(ya)或(huo)通(tong)用(yong)驅動(dong)器(qi)(qi)(qi)(qi)。原理是(shi)使用(yong)降(jiang)壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)將(jiang)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)低到低壓(ya)(ya)(ya)逆變器(qi)(qi)(qi)(qi)的標稱或(huo)允許(xu)電(dian)(dian)(dian)壓(ya)(ya)(ya)輸(shu)入范圍。通(tong)過對逆變器(qi)(qi)(qi)(qi)進(jin)行轉(zhuan)換(huan)(huan)，然(ran)后將(jiang)其從升(sheng)壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)轉(zhuan)換(huan)(huan)為所(suo)需的電(dian)(dian)(dian)動(dong)機，可(ke)以(yi)(yi)形成頻率和幅度可(ke)變的交流電(dian)(dian)(dian)源(yuan)。電(dian)(dian)(dian)壓(ya)(ya)(ya)等級。如果運行中(zhong)(zhong)的變壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)有兩個或(huo)更多(duo)個接地故(gu)障，則在鐵(tie)芯(xin)的工作磁(ci)通(tong)周圍會形成短(duan)路(lu)匝。短(duan)路(lu)匝會產生大的渦(wo)流和循(xun)環(huan)(huan)電(dian)(dian)(dian)流，以(yi)(yi)加熱鐵(tie)芯(xin)，升(sheng)高(gao)(gao)油溫，使邊緣碳化，并(bing)產生可(ke)燃(ran)氣(qi)體，從而導(dao)致輕質氣(qi)體的連續運動(dong)。如果接地不好(hao)，則循(xun)環(huan)(huan)可(ke)能是(shi)暫(zan)時的，從而導(dao)致輪輞油松(song)動(dong)并(bing)碳化。此時，應(ying)通(tong)過色譜(pu)法(fa)(fa)對油進(jin)行分析，以(yi)(yi)確(que)定故(gu)障的性質。
