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(ci)線圈的(de)(de)(de)電氣(qi)設備，要建立(li)磁(ci)場，就要消耗無功(gong)(gong)(gong)功(gong)(gong)(gong)率。比如(ru)40瓦的(de)(de)(de)日光(guang)燈，除需40多(duo)瓦有功(gong)(gong)(gong)功(gong)(gong)(gong)率(鎮流(liu)器也需消耗一部分有功(gong)(gong)(gong)功(gong)(gong)(gong)率)來發(fa)光(guang)外，還需80乏(fa)左右的(de)(de)(de)無功(gong)(gong)(gong)功(gong)(gong)(gong)率供鎮流(liu)器的(de)(de)(de)線圈建立(li)交(jiao)變磁(ci)場用(yong)。由于它不對(dui)外做功(gong)(gong)(gong)，才被稱之(zhi)為“無功(gong)(gong)(gong)”。無功(gong)(gong)(gong)功(gong)(gong)(gong)率的(de)(de)(de)符號用(yong)Q表示，單位為乏(fa)(Var)或千乏(fa)(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(yi)過一段時間以后發覺交流接觸器(qi)又(you)壞了，要是沒有想起是由于投切經常造成(cheng)的交流接觸器(qi)毀(hui)壞，這類就全靠(kao)拆換交流接觸器(qi)湊合再次應用。

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(rong)器、動態投切單元、刀熔開關(guan)、連接母(mu)排、導線、端子等(deng)元器件組成(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。 它安裝在架空線路的(de)(de)(de)桿或塔上(shang)，并可以(yi)根據無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)和電(dian)(dian)壓(ya)(ya)自動調節以(yi)進行(xing)無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)補(bu)(bu)償，以(yi)提(ti)(ti)高(gao)配電(dian)(dian)網(wang)的(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)率(lv)因數(shu)，從而達到減少損耗和提(ti)(ti)高(gao)電(dian)(dian)壓(ya)(ya)的(de)(de)(de)目的(de)(de)(de)。 適用(yong)于大(da)量公共變(bian)壓(ya)(ya)器(qi)無低(di)壓(ya)(ya)無功(gong)(gong)(gong)(gong)(gong)補(bu)(bu)償的(de)(de)(de)輸(shu)電(dian)(dian)線路，以(yi)幫(bang)助提(ti)(ti)高(gao)輸(shu)電(dian)(dian)網(wang)的(de)(de)(de)電(dian)(dian)壓(ya)(ya)。
