10KV高壓無功補償裝置采用先進的無功功率控制器
10KV高壓無功自動補償裝置為積木(mu)式(shi)設(she)計,各(ge)柜體采(cai)用硬母線連接,運行可靠,可擴充柜數增加(jia)容(rong)量(liang)(liang)。該裝置應(ying)在各(ge)種(zhong)工(gong)作條件下進行共振驗證(zheng)。選(xuan)擇單組容(rong)量(liang)(liang)時,盡(jin)量(liang)(liang)避(bi)開諧振放大區,或選(xuan)擇合適的電抗率,避(bi)開諧振條件,保證(zheng)裝置在各(ge)種(zhong)工(gong)況(kuang)下安全運行。
MSCHA高壓無功自動補償(chang)裝置(zhi)采用先進(jin)的(de)無功功率控制器(qi),能實時在線監測系(xi)統(tong)(tong)的(de)無功功率因數,實時跟蹤投切。也可根據(ju)用戶(hu)要(yao)求配備RS232/485通信接口(kou),將整個裝置(zhi)的(de)運行數據(ju)上傳至監控系(xi)統(tong)(tong)。除了使用噴霧熔(rong)斷(duan)器(qi)或內部熔(rong)斷(duan)器(qi)作(zuo)為單個電容器(qi)的(de)過(guo)流(liu)保(bao)護之外,還提供零序電壓保(bao)護。
那(nei)么無功補(bu)償的(de)原理是什么呢?
電(dian)(dian)(dian)網(wang)(wang)的輸出功(gong)(gong)(gong)率(lv)包括無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)和(he)有(you)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv),其中(zhong)有(you)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)是(shi)(shi)指直接(jie)消耗(hao)電(dian)(dian)(dian)能(neng)(neng)(neng)并(bing)直接(jie)轉化(hua)為熱能(neng)(neng)(neng)、化(hua)學能(neng)(neng)(neng)、機械能(neng)(neng)(neng)、聲能(neng)(neng)(neng)而產生的功(gong)(gong)(gong)率(lv)。無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)是(shi)(shi)指不消耗(hao)電(dian)(dian)(dian)能(neng)(neng)(neng),只是(shi)(shi)將電(dian)(dian)(dian)能(neng)(neng)(neng)轉化(hua)為另(ling)一種形式的能(neng)(neng)(neng)量。這種能(neng)(neng)(neng)量是(shi)(shi)電(dian)(dian)(dian)氣設(she)備做(zuo)功(gong)(gong)(gong)的必要條件,可以周期性地與電(dian)(dian)(dian)網(wang)(wang)中(zhong)的電(dian)(dian)(dian)能(neng)(neng)(neng)進行轉換。這部分(fen)功(gong)(gong)(gong)率(lv)稱為無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)。當帶(dai)容(rong)(rong)性功(gong)(gong)(gong)率(lv)負(fu)(fu)載(zai)的裝置(zhi)和(he)帶(dai)感(gan)性功(gong)(gong)(gong)率(lv)負(fu)(fu)載(zai)的裝置(zhi)并(bing)聯在同一電(dian)(dian)(dian)路中(zhong)時,能(neng)(neng)(neng)量可以在兩個(ge)負(fu)(fu)載(zai)之間來回轉換,感(gan)性負(fu)(fu)載(zai)所需的無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)可以由容(rong)(rong)性負(fu)(fu)載(zai)輸出的無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)來補償。
