電容器(qi)(qi)柜(ju)：也(ye)稱為補(bu)償柜(ju)。它用于改善(shan)電網的(de)功(gong)率因數或(huo)(huo)補(bu)償無功(gong)功(gong)率。主要組件是并(bing)聯(lian)的(de)電容器(qi)(qi)組，開關控制回路和保險絲組。使用電器(qi)(qi)。帶有輸入機柜(ju)的(de)普通并(bing)聯(lian)設備，可以并(bing)行操作一個或(huo)(huo)多個電容器(qi)(qi)柜(ju)。

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。在執行自動控制功(gong)能時，請注(zhu)意每組(zu)電容(rong)器組(zu)的(de)開(kai)關(guan)時間的(de)適當分配，以(yi)免出現一組(zu)電容(rong)器損壞而其他組(zu)很少導通的(de)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。中的每個分支斷路器(qi)應使(shi)用(yong)(yong)多(duo)少額(e)定電(dian)流？無(wu)論是用(yong)(yong)于(yu)家庭(ting)還是其他應用(yong)(yong)，現代照明設備都(dou)使(shi)用(yong)(yong)純(chun)電(dian)阻(zu)燈和燈籠。

通常使用節(jie)能燈(deng)，熒光燈(deng)和(he)其(qi)他燈(deng)以(yi)及空調系(xi)統。像電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機這(zhe)樣的(de)(de)(de)負(fu)載很常見。由于這(zhe)種(zhong)類型的(de)(de)(de)負(fu)載包含電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感性(xing)非線性(xing)負(fu)載，因此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流波形變得極為不規則，普通的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表無法測量諧波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱生(sheng)產廠(chang)家(jia)只(zhi)需根(gen)據計(ji)算(suan)出(chu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流選(xuan)擇斷(duan)(duan)路器(qi)。額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不合適，因此(ci)應(ying)根(gen)據實(shi)際負(fu)載組成進(jin)行考慮(lv)。例如，對于某些具有大功率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機的(de)(de)(de)負(fu)載，應(ying)選(xuan)擇一個斷(duan)(duan)路器(qi)來保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機。這(zhe)就解釋(shi)了為什么是這(zhe)種(zhong)情況，根(gen)據計(ji)算(suan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣間(jian)隙選(xuan)擇的(de)(de)(de)斷(duan)(duan)路器(qi)仍然(ran)經常過(guo)載，并且端(duan)子的(de)(de)(de)溫度(du)始終很高。
