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)配電(dian)(dian)柜(ju)必須懲罰級(ji)配電(dian)(dian)柜(ju)分配的電(dian)(dian)能。第(di)三級(ji)配電(dian)(dian)柜(ju)是(shi)光通量配電(dian)(dian)柜(ju)。由于我們分散了其布(bu)局(ju)，因此容量相(xiang)對較低。配電(dian)(dian)柜(ju)可(ke)以為我們的生活提供安全保障，因此必須安裝配電(dian)(dian)柜(ju)，并根據情(qing)況將其隱(yin)藏在(zai)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(dian)是否可(ke)靠焊接(jie)。電(dian)(dian)動(dong)或機械(xie)鎖定(ding)(ding)正確(que)，因此(ci)手(shou)推(tui)(tui)車無法在關(guan)閉位置(zhi)拉出(chu)。安全隔板易于打開和關(guan)閉，并且可(ke)以通過(guo)手(shou)推(tui)(tui)車進行(xing)伸縮。手(shou)車的(de)接(jie)地(di)裝置(zhi)應與高壓配電(dian)(dian)柜的(de)固定(ding)(ding)框架良(liang)好接(jie)觸。高低(di)壓開關(guan)柜中(zhong)的(de)控制電(dian)(dian)纜(lan)已牢固固定(ding)(ding)，不會影響手(shou)推(tui)(tui)車的(de)移動(dong)。

高(gao)-低-高(gao)頻轉換(huan)器(qi)：應(ying)用(yong)上下方法(fa)在中(zhong)(zhong)高(gao)壓(ya)(ya)(ya)(ya)環(huan)境中(zhong)(zhong)應(ying)用(yong)低壓(ya)(ya)(ya)(ya)或(huo)通用(yong)驅(qu)動(dong)器(qi)。原理是使用(yong)降壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)將電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)降低到低壓(ya)(ya)(ya)(ya)逆(ni)變(bian)(bian)(bian)器(qi)的(de)(de)標(biao)稱(cheng)或(huo)允(yun)許電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)輸入范(fan)圍。通過(guo)對逆(ni)變(bian)(bian)(bian)器(qi)進行轉換(huan)，然后(hou)將其從(cong)(cong)升壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)轉換(huan)為所需的(de)(de)電(dian)(dian)(dian)動(dong)機，可以(yi)形成(cheng)頻率和幅度(du)可變(bian)(bian)(bian)的(de)(de)交流(liu)(liu)電(dian)(dian)(dian)源。電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)等級。如果運(yun)行中(zhong)(zhong)的(de)(de)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)有兩(liang)個或(huo)更多個接地(di)故障(zhang)，則在鐵芯的(de)(de)工(gong)作磁通周圍會形成(cheng)短路(lu)匝(za)。短路(lu)匝(za)會產生(sheng)(sheng)大的(de)(de)渦流(liu)(liu)和循環(huan)電(dian)(dian)(dian)流(liu)(liu)，以(yi)加熱鐵芯，升高(gao)油(you)溫，使邊(bian)緣碳化，并產生(sheng)(sheng)可燃氣(qi)體，從(cong)(cong)而(er)導(dao)致輕質氣(qi)體的(de)(de)連續運(yun)動(dong)。如果接地(di)不好，則循環(huan)可能(neng)是暫時(shi)的(de)(de)，從(cong)(cong)而(er)導(dao)致輪輞(wang)油(you)松動(dong)并碳化。此(ci)時(shi)，應(ying)通過(guo)色譜法(fa)對油(you)進行分析，以(yi)確定故障(zhang)的(de)(de)性質。
