無(wu)功(gong)(gong)(gong)(gong)補償的基本原理:電網輸出(chu)的功(gong)(gong)(gong)(gong)率包(bao)括兩(liang)部分(fen);一是有功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率,二(er)是無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率,前者(zhe)直接消(xiao)耗電能(neng)(neng)(neng),把電能(neng)(neng)(neng)轉(zhuan)變為機(ji)械能(neng)(neng)(neng)、熱能(neng)(neng)(neng)、化學能(neng)(neng)(neng)或聲能(neng)(neng)(neng),利用這些能(neng)(neng)(neng)做功(gong)(gong)(gong)(gong),這部分(fen)功(gong)(gong)(gong)(gong)率稱為有功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率其消(xiao)耗電能(neng)(neng)(neng),只(zhi)是把電能(neng)(neng)(neng)轉(zhuan)換為另一種形(xing)式的能(neng)(neng)(neng)。后者(zhe)這種能(neng)(neng)(neng)作為電氣(qi)設備能(neng)(neng)(neng)夠作功(gong)(gong)(gong)(gong)的必(bi)備條件,并且這種能(neng)(neng)(neng)是在電網中與電能(neng)(neng)(neng)進行周期(qi)性(xing)轉(zhuan)換,這部分(fen)功(gong)(gong)(gong)(gong)率稱為無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率。

安裝濾波補償模組的基本常識

在(zai)這個時候(hou)無功(gong)功(gong)率(lv)的補償器(qi)電阻的抵(di)(di)抗(kang)就是(shi)可以接受的，而與用電負(fu)載進(jin)行(xing)并聯之后就能降低(di)它的感抗(kang)性能，使得(de)功(gong)率(lv)因數變(bian)大(da)(da)，無功(gong)功(gong)率(lv)的因數就相對變(bian)小(xiao);相反，當用電負(fu)載是(shi)容性負(fu)載的時候(hou)，電流(liu)速度就會在(zai)電壓(ya)的前面，我們要調節(jie)晶(jing)閘管的導通角度，使得(de)可變(bian)性的電抗(kang)器(qi)的電阻抵(di)(di)抗(kang)力變(bian)大(da)(da)，一直到大(da)(da)于一定(ding)的期望(wang)值。

若進(jin)(jin)線(xian)回路(lu)有(you)兩(liang)條，情況(kuang)稍(shao)為(wei)復雜一(yi)些。此時(shi)通常將兩(liang)回進(jin)(jin)線(xian)柜安排在(zai)主(zhu)母(mu)線(xian)的(de)左右兩(liang)端(duan)，這樣電(dian)(dian)流(liu)(liu)的(de)流(liu)(liu)向分布更(geng)為(wei)合理，主(zhu)母(mu)線(xian)的(de)截(jie)面(mian)就(jiu)可以不按兩(liang)進(jin)(jin)路(lu)電(dian)(dian)流(liu)(liu)之和來選(xuan)取。這時(shi)，主(zhu)母(mu)線(xian)截(jie)面(mian)應在(zai)較大(da)進(jin)(jin)路(lu)電(dian)(dian)流(liu)(liu)至兩(liang)路(lu)電(dian)(dian)流(liu)(liu)之和的(de)電(dian)(dian)流(liu)(liu)范圍內考慮(lv)，具(ju)體取多大(da)要看進(jin)(jin)出柜布置(zhi)情況(kuang)，分析(xi)電(dian)(dian)流(liu)(liu)流(liu)(liu)向分布后決(jue)定。
