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(er)級配電(dian)(dian)(dian)(dian)柜(ju)必須懲罰(fa)級配電(dian)(dian)(dian)(dian)柜(ju)分(fen)配的電(dian)(dian)(dian)(dian)能(neng)。第三級配電(dian)(dian)(dian)(dian)柜(ju)是光通量配電(dian)(dian)(dian)(dian)柜(ju)。由于(yu)我們(men)分(fen)散(san)了其布局，因(yin)此容量相對較低。配電(dian)(dian)(dian)(dian)柜(ju)可以為我們(men)的生活提(ti)供安全保(bao)障，因(yin)此必須安裝配電(dian)(dian)(dian)(dian)柜(ju)，并根據情況(kuang)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(lu)的插頭和輔助觸(chu)點是否可靠焊接。電動(dong)或機械鎖定(ding)正確，因此手(shou)推(tui)車無(wu)法在(zai)關閉(bi)位置拉出。安(an)全(quan)隔板易于打開和關閉(bi)，并且可以通過手(shou)推(tui)車進行伸縮。手(shou)車的接地裝置應與高壓(ya)(ya)配電柜(ju)(ju)的固定(ding)框(kuang)架良好接觸(chu)。高低壓(ya)(ya)開關柜(ju)(ju)中的控(kong)制電纜已牢固固定(ding)，不會(hui)影(ying)響(xiang)手(shou)推(tui)車的移動(dong)。

高-低(di)(di)-高頻轉換器(qi)(qi)：應(ying)用(yong)上下方法在(zai)中高壓(ya)(ya)(ya)環(huan)境中應(ying)用(yong)低(di)(di)壓(ya)(ya)(ya)或(huo)通(tong)(tong)用(yong)驅動器(qi)(qi)。原理是(shi)使(shi)用(yong)降(jiang)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)將電(dian)網(wang)電(dian)壓(ya)(ya)(ya)降(jiang)低(di)(di)到低(di)(di)壓(ya)(ya)(ya)逆變(bian)(bian)(bian)(bian)器(qi)(qi)的(de)(de)(de)標稱或(huo)允許電(dian)壓(ya)(ya)(ya)輸入范圍。通(tong)(tong)過對逆變(bian)(bian)(bian)(bian)器(qi)(qi)進(jin)行(xing)(xing)轉換，然后將其從(cong)(cong)升(sheng)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)轉換為所(suo)需的(de)(de)(de)電(dian)動機，可(ke)以形成頻率和(he)幅度可(ke)變(bian)(bian)(bian)(bian)的(de)(de)(de)交流電(dian)源。電(dian)壓(ya)(ya)(ya)等級。如果(guo)運行(xing)(xing)中的(de)(de)(de)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)有(you)兩個(ge)或(huo)更多個(ge)接地(di)故障(zhang)，則在(zai)鐵芯(xin)(xin)的(de)(de)(de)工作(zuo)磁(ci)通(tong)(tong)周圍會形成短路匝。短路匝會產(chan)生(sheng)大的(de)(de)(de)渦流和(he)循(xun)環(huan)電(dian)流，以加(jia)熱鐵芯(xin)(xin)，升(sheng)高油(you)溫，使(shi)邊緣碳化，并產(chan)生(sheng)可(ke)燃(ran)氣體(ti)(ti)，從(cong)(cong)而導(dao)致(zhi)(zhi)輕質氣體(ti)(ti)的(de)(de)(de)連續(xu)運動。如果(guo)接地(di)不好，則循(xun)環(huan)可(ke)能是(shi)暫時的(de)(de)(de)，從(cong)(cong)而導(dao)致(zhi)(zhi)輪輞油(you)松動并碳化。此時，應(ying)通(tong)(tong)過色譜法對油(you)進(jin)行(xing)(xing)分析，以確定故障(zhang)的(de)(de)(de)性質。
