電(dian)容(rong)器柜：也(ye)稱(cheng)為補償(chang)柜。它用于改善(shan)電(dian)網(wang)的功率(lv)因數或補償(chang)無功功率(lv)。主(zhu)要組(zu)件(jian)是并(bing)聯的電(dian)容(rong)器組(zu)，開關控制(zhi)回路和保險絲組(zu)。使用電(dian)器。帶有(you)輸入機柜的普通并(bing)聯設備(bei)，可以(yi)并(bing)行(xing)操(cao)作(zuo)一個或多個電(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。在執行自動控制功能(neng)時(shi)，請注意每(mei)組電(dian)容(rong)器組的(de)(de)開關時(shi)間的(de)(de)適當分配，以免出現一組電(dian)容(rong)器損壞而其他組很少(shao)導通(tong)的(de)(de)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。中的每個分支斷路器(qi)應使(shi)用(yong)(yong)(yong)多少額定(ding)電流？無論是用(yong)(yong)(yong)于家(jia)庭(ting)還是其他應用(yong)(yong)(yong)，現(xian)代照明設備(bei)都使(shi)用(yong)(yong)(yong)純(chun)電阻燈和燈籠。

通常使用節能燈(deng)(deng)，熒(ying)光燈(deng)(deng)和其他燈(deng)(deng)以及空調系統。像電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機這樣(yang)的負(fu)載很(hen)常見。由(you)于(yu)這種類型的負(fu)載包含電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感性非線性負(fu)載，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)波形變得極為不規則，普通的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表無法(fa)測(ce)量諧(xie)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱生產(chan)廠家只(zhi)需(xu)根(gen)據計算(suan)出的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)選(xuan)擇(ze)斷(duan)路(lu)器(qi)。額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不合適，因此應(ying)根(gen)據實際負(fu)載組成進行考(kao)慮。例如(ru)，對于(yu)某(mou)些具有大功率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機的負(fu)載，應(ying)選(xuan)擇(ze)一個斷(duan)路(lu)器(qi)來保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機。這就(jiu)解(jie)釋了為什么是這種情況，根(gen)據計算(suan)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣間隙選(xuan)擇(ze)的斷(duan)路(lu)器(qi)仍然經(jing)常過(guo)載，并(bing)且端子的溫度(du)始終很(hen)高(gao)。
