電容柜全稱無功功率補償，是一種在電力供電系統中起提高電網的功率因數的作用，降低供電變壓器及輸送線路的損耗，提高供電效率，改善供電環境的技術。所以黑龍江電容柜在(zai)(zai)電(dian)(dian)力(li)供(gong)電(dian)(dian)系統中處在(zai)(zai)一個不可(ke)缺少的非常重要的位(wei)置。合理(li)的選擇(ze)(ze)無功補償裝置，可(ke)以做到(dao)最大(da)限(xian)度的減少電(dian)(dian)網的損耗，使電(dian)(dian)網質量提高(gao)。反(fan)之，如選擇(ze)(ze)或使用不當，可(ke)能(neng)造(zao)成供(gong)電(dian)(dian)系統，電(dian)(dian)壓波動，諧波增(zeng)大(da)等(deng)諸多因素。

一般大型企業采用大量用電設備，包括電感電動機、變壓器等。電容柜價格供電系統中既包括有功功率，又包括無功功率，使發電設備和輸電設備不能充分發揮作用，黑龍江電容柜并增加輸電(dian)線路的(de)(de)(de)功(gong)率(lv)(lv)損(sun)耗和(he)電(dian)壓損(sun)失(shi)，故(gu)提(ti)高用戶的(de)(de)(de)功(gong)率(lv)(lv)因數有如(ru)下益處。①提(ti)高電(dian)力系統(tong)的(de)(de)(de)供(gong)電(dian)能力；②減少網(wang)絡中的(de)(de)(de)電(dian)壓損(sun)失(shi)，提(ti)高供(gong)電(dian)質量；③降低網(wang)絡中的(de)(de)(de)功(gong)率(lv)(lv)損(sun)耗。

高壓電容柜比較抽象，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。電容柜價格凡是有電(dian)磁線圈(quan)(quan)的電(dian)氣設備，要建立磁場(chang)，就要消(xiao)耗無功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)。比如40瓦的日光燈，除(chu)需40多瓦有功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(鎮(zhen)(zhen)流器也需消(xiao)耗一部分有功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv))來發光外，還需80乏左(zuo)右(you)的無功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)供鎮(zhen)(zhen)流器的線圈(quan)(quan)建立交(jiao)變磁場(chang)用(yong)。由于(yu)它不對(dui)外做功(gong)(gong)(gong)(gong)(gong)(gong)，才被稱之(zhi)為“無功(gong)(gong)(gong)(gong)(gong)(gong)”。無功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)的符號用(yong)Q表示，單位為乏(Var)或千(qian)乏(kVar)。

黑龍江電容柜高壓集中補償方式。優點：采用高壓集中補償的初期，投資要求較低。6~10KV母線上產生的無功功率其曲線變化比較平穩，便于運行管理和調節，而且利用率高，可提高企業供電系統的變壓器的負荷能力。 黑龍江高壓電容柜缺點：高壓集中(zhong)補償方式對(dui)環境要(yao)求(qiu)高，需(xu)要(yao)設有(you)專(zhuan)門(men)的電容器室，并(bing)且(qie)通(tong)風好，室內(nei)溫度適(shi)宜，并(bing)要(yao)求(qiu)有(you)可靠的放電設備。
