電力無功補償器比較抽象，它是用于電路內電場與磁場的交換，并用來在電氣設備中建立和維持磁場的電功率。它不對外作功，而是轉變為其他形式的能量。無功補償器廠家凡是有電磁線(xian)(xian)圈(quan)的(de)(de)電氣設(she)備，要建立磁場，就要消耗無(wu)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)。比如40瓦的(de)(de)日光燈，除(chu)需(xu)40多瓦有功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(鎮流器也需(xu)消耗一部分(fen)有功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv))來發光外，還需(xu)80乏左(zuo)右(you)的(de)(de)無(wu)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)供(gong)鎮流器的(de)(de)線(xian)(xian)圈(quan)建立交變磁場用。由于(yu)它(ta)不對外做功(gong)(gong)(gong)(gong)(gong)(gong)，才被稱之為“無(wu)功(gong)(gong)(gong)(gong)(gong)(gong)”。無(wu)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)的(de)(de)符號(hao)用Q表(biao)示，單位為乏(Var)或千乏(kVar)。

電力無功補償器一般來說客戶的第一反應并不是控制板的難題，一般會認為是交流接觸器的品質不合格，只把交流接觸器換了再次應用，顯而易見是沒有處理壓根難題的。湖北無功補償器已過一段時間以后發覺交流接(jie)(jie)觸器(qi)(qi)又壞了，要是(shi)沒有想起是(shi)由于投(tou)切經常造(zao)成的交流接(jie)(jie)觸器(qi)(qi)毀壞，這類就全靠拆換交流接(jie)(jie)觸器(qi)(qi)湊合再(zai)次應用。

電力無功補償器裝置是一款集動態無功補償及諧波治理于一體的智能控制產品。它通過合理的結構設計和專業的散熱設計將無功補償及諧波治理組件與進口可控硅投切單元組合成模塊形式，采用可控硅對濾波模塊進行電壓過零投入與電流過零切除，實現模塊的動態投切（≤20ms）。湖北無功補償器主要由濾(lv)波電抗器、濾(lv)波補償電容器、動(dong)態投切單元、刀熔開關(guan)、連接(jie)母排、導(dao)線(xian)、端子等元器件組(zu)成(cheng)。

柱上安裝的高壓電容柜主要用于10kv（6kv）配電線路上的電力無功補償器。 它安裝(zhuang)在架空線路的(de)(de)桿或塔上，并可以根據無功(gong)功(gong)率(lv)和電壓(ya)自(zi)動調節(jie)以進行無功(gong)功(gong)率(lv)補償(chang)，以提(ti)高(gao)配(pei)電網(wang)的(de)(de)功(gong)率(lv)因數，從而達(da)到減少(shao)損耗和提(ti)高(gao)電壓(ya)的(de)(de)目的(de)(de)。 適用于(yu)大量公共變壓(ya)器(qi)無低(di)壓(ya)無功(gong)補償(chang)的(de)(de)輸(shu)電線路，以幫助(zhu)提(ti)高(gao)輸(shu)電網(wang)的(de)(de)電壓(ya)。
