電(dian)(dian)容(rong)器(qi)柜(ju)(ju)：也稱為補(bu)償(chang)柜(ju)(ju)。它(ta)用(yong)于改善電(dian)(dian)網的(de)功率因數(shu)或(huo)補(bu)償(chang)無功功率。主要組件是并聯的(de)電(dian)(dian)容(rong)器(qi)組，開關控制回路和保險絲組。使用(yong)電(dian)(dian)器(qi)。帶有輸入機柜(ju)(ju)的(de)普通并聯設備，可以并行操作一個或(huo)多個電(dian)(dian)容(rong)器(qi)柜(ju)(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。在執行自動控制功能(neng)時(shi)，請注意每組(zu)電(dian)容(rong)器(qi)(qi)組(zu)的開(kai)關(guan)時(shi)間的適當(dang)分配，以免(mian)出現一組(zu)電(dian)容(rong)器(qi)(qi)損(sun)壞(huai)而其他組(zu)很少(shao)導通的情況。

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(zhong)的每個分支斷(duan)路器(qi)應使用(yong)多少額定電流？無論是(shi)用(yong)于(yu)家庭還是(shi)其他應用(yong)，現代照(zhao)明設備都使用(yong)純電阻燈和燈籠。

通常使用節能燈，熒光燈和(he)其他燈以及(ji)空(kong)調(diao)系(xi)統。像(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機這(zhe)樣的(de)(de)負(fu)(fu)載(zai)(zai)很(hen)常見(jian)。由于(yu)這(zhe)種(zhong)類型(xing)的(de)(de)負(fu)(fu)載(zai)(zai)包含電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感性(xing)非線性(xing)負(fu)(fu)載(zai)(zai)，因(yin)此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流波形變(bian)得極為不規則，普通的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表無法測(ce)量諧波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱生(sheng)產廠家只需(xu)根據計算出(chu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流選(xuan)擇斷(duan)路器。額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不合(he)適(shi)，因(yin)此應根據實際負(fu)(fu)載(zai)(zai)組成(cheng)進行考慮。例如，對于(yu)某些具有大功率(lv)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機的(de)(de)負(fu)(fu)載(zai)(zai)，應選(xuan)擇一個斷(duan)路器來保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機。這(zhe)就解釋了為什么是這(zhe)種(zhong)情況，根據計算的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)間隙(xi)選(xuan)擇的(de)(de)斷(duan)路器仍然經(jing)常過(guo)載(zai)(zai)，并且端子的(de)(de)溫度(du)始(shi)終很(hen)高。
