隨著科學技術的進(jin)步和(he)人民(min)生活水平的提高,配電系統(tong)結構日益復雜,尤其當今企業對電動(dong)機(ji)、整流裝置、變頻器等用(yong)(yong)電設備(bei)的大量使用(yong)(yong),導致用(yong)(yong)電不足現(xian)象,使得功率因素偏低(di),不僅對用(yong)(yong)電設備(bei)利用(yong)(yong)率較低(di),電能損(sun)耗(hao)成本增(zeng)加,而且對低(di)壓(ya)配電系統(tong)造成損(sun)耗(hao)和(he)污(wu)染,所(suo)以(yi)急需對電能質量問題進(jin)行治理(li)。
現(xian)在廣泛的治理方法是在低壓(ya)配(pei)電系統中采(cai)用(yong)并(bing)聯電容器對其進行無功補償,下面小希用(yong)實(shi)際案例來(lai)與大家分(fen)享一(yi)下關(guan)于低壓(ya)無功補償裝置的技術改造及應(ying)用(yong):
根據配電(dian)室的(de)(de)位置(zhi)以及現場情況勘察,決定首先安裝低壓電(dian)力電(dian)容器(qi)(qi)(qi)(qi)(qi)補償容量,電(dian)容器(qi)(qi)(qi)(qi)(qi)此(ci)次(ci)選擇希(xi)拓(tuo)電(dian)氣(qi)氮氣(qi)填充的(de)(de)干式電(dian)容器(qi)(qi)(qi)(qi)(qi),其具(ju)有自(zi)愈功能,安全(quan)性更高,同時串聯上純銅繞組的(de)(de)電(dian)抗器(qi)(qi)(qi)(qi)(qi),在保護電(dian)容器(qi)(qi)(qi)(qi)(qi)的(de)(de)安全(quan)和穩定性的(de)(de)同時消除諧波。
對(dui)配(pei)電(dian)(dian)房(fang)無(wu)功(gong)(gong)補(bu)償柜改造后,該企業功(gong)(gong)率因(yin)素顯示在(zai)0.95左右(you),電(dian)(dian)壓也(ye)由原(yuan)來的375V左右(you)提高到了380V左右(you), 電(dian)(dian)流(liu)也(ye)有(you)所降低(di)。通過此次(ci)(ci)電(dian)(dian)容柜改造項目,提高了企業設備利用率,減(jian)少了電(dian)(dian)能損耗(hao),節(jie)省電(dian)(dian)費并產(chan)生了一定經(jing)濟效(xiao)應,此次(ci)(ci)無(wu)功(gong)(gong)補(bu)償改造圓滿成功(gong)(gong)!
