電(dian)(dian)(dian)容(rong)器柜：也稱為(wei)補償柜。它(ta)用于改善電(dian)(dian)(dian)網的功(gong)率因(yin)數或補償無功(gong)功(gong)率。主要組(zu)件是并聯的電(dian)(dian)(dian)容(rong)器組(zu)，開關控制回(hui)路和保險絲(si)組(zu)。使用電(dian)(dian)(dian)器。帶(dai)有輸入(ru)機柜的普通并聯設(she)備，可以并行操作一個或多個電(dian)(dian)(dian)容(rong)器柜。

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(xing)自(zi)動控(kong)制功能時(shi)，請注(zhu)意每(mei)組(zu)電(dian)容器組(zu)的開關時(shi)間(jian)的適當分配，以免(mian)出現一組(zu)電(dian)容器損(sun)壞而(er)其他(ta)組(zu)很少導(dao)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(mei)個分支斷路器應(ying)使用(yong)多少(shao)額定電流？無(wu)論是(shi)用(yong)于家庭還是(shi)其他應(ying)用(yong)，現代照明設備都(dou)使用(yong)純電阻燈和燈籠。

通(tong)常使用節能(neng)燈，熒光(guang)燈和(he)其(qi)他燈以及(ji)空調系統。像電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)這(zhe)(zhe)樣(yang)的(de)(de)(de)(de)負載很常見(jian)。由(you)于這(zhe)(zhe)種類型的(de)(de)(de)(de)負載包含電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)性(xing)(xing)非線性(xing)(xing)負載，因(yin)此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)波形變得(de)極為(wei)不(bu)規則，普通(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表無法(fa)測量諧波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱生產廠家(jia)只需根(gen)據(ju)計算(suan)出的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)選(xuan)擇(ze)斷(duan)路(lu)(lu)器。額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不(bu)合適(shi)，因(yin)此應根(gen)據(ju)實際負載組成(cheng)進行(xing)考慮(lv)。例如，對于某些具有大功(gong)率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)(de)負載，應選(xuan)擇(ze)一個斷(duan)路(lu)(lu)器來保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)。這(zhe)(zhe)就解釋了(le)為(wei)什(shen)么是這(zhe)(zhe)種情況，根(gen)據(ju)計算(suan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)間隙(xi)選(xuan)擇(ze)的(de)(de)(de)(de)斷(duan)路(lu)(lu)器仍然經(jing)常過載，并且端子的(de)(de)(de)(de)溫(wen)度始終(zhong)很高(gao)。
