電(dian)(dian)容(rong)器(qi)柜：也稱(cheng)為(wei)補償柜。它用(yong)于改善電(dian)(dian)網(wang)的(de)(de)功率因數或補償無功功率。主要組(zu)件是并(bing)(bing)聯的(de)(de)電(dian)(dian)容(rong)器(qi)組(zu)，開(kai)關控制回路和保險絲組(zu)。使用(yong)電(dian)(dian)器(qi)。帶有輸入機柜的(de)(de)普通并(bing)(bing)聯設備，可(ke)以并(bing)(bing)行(xing)操作(zuo)一個或多個電(dian)(dian)容(rong)器(qi)柜。

斷開電容器柜與電源的連接后，在停電后的一定時間內（根據電容器組），不能直接觸摸機柜中的組件，尤其是電容器組，因為電容器組需要一定的時間才能完成放電過程根據電容器的大小（例如1分鐘），可能不會再次合上電容器，以免損壞電容器的過電壓。在執行自(zi)動控制功能(neng)時，請注(zhu)意每(mei)組(zu)(zu)(zu)電容器組(zu)(zu)(zu)的開關時間的適當分配，以免(mian)出(chu)現一組(zu)(zu)(zu)電容器損壞而其他組(zu)(zu)(zu)很(hen)少導通的情(qing)況。

必須根據制造商的使用說明書中指定的功率降低規定來使用斷路器，并且如果條件允許，可以通過測試確定斷路器。中的每個分(fen)支斷路(lu)器應(ying)使(shi)(shi)用(yong)多少(shao)額(e)定電流？無(wu)論是用(yong)于家庭(ting)還是其他應(ying)用(yong)，現(xian)代照(zhao)明設備都使(shi)(shi)用(yong)純電阻(zu)燈(deng)和(he)燈(deng)籠。

通常使用節能燈，熒光燈和其他燈以(yi)及空調系(xi)統。像電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)這樣的(de)負(fu)載(zai)(zai)(zai)很常見。由于這種(zhong)類(lei)型的(de)負(fu)載(zai)(zai)(zai)包含(han)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)感性非線性負(fu)載(zai)(zai)(zai)，因(yin)此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流波形變(bian)得極為(wei)不(bu)規則(ze)，普(pu)通的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表(biao)無法(fa)測量諧(xie)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱生產(chan)廠家只需根據(ju)計算出的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流選擇斷(duan)路(lu)器。額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不(bu)合適，因(yin)此(ci)應根據(ju)實際(ji)負(fu)載(zai)(zai)(zai)組成(cheng)進行考慮。例如，對于某些具(ju)有大(da)功率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)負(fu)載(zai)(zai)(zai)，應選擇一個斷(duan)路(lu)器來保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)。這就解釋了為(wei)什(shen)么是這種(zhong)情況，根據(ju)計算的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣間隙(xi)選擇的(de)斷(duan)路(lu)器仍然(ran)經常過載(zai)(zai)(zai)，并且端子的(de)溫(wen)度始終很高。
