電力濾波電容器在改(gai)善(shan)供電(dian)系(xi)統中電(dian)網(wang)(wang)的(de)功率因數，減少供電(dian)變(bian)壓(ya)(ya)器(qi)和輸(shu)電(dian)線(xian)路的(de)損耗(hao)，提高(gao)供電(dian)效率以(yi)及改(gai)善(shan)供電(dian)環境方面發揮著作用(yong)。合理選擇(ze)補償裝置可(ke)以(yi)最大程度地(di)減少電(dian)網(wang)(wang)損耗(hao)，提高(gao)電(dian)網(wang)(wang)質量。相(xiang)反(fan)，選擇(ze)或使用(yong)不當可(ke)能會導(dao)致許多因素，例如(ru)電(dian)源系(xi)統，電(dian)壓(ya)(ya)波動和諧波增加。

電力濾波電容器為直動式雙斷點結構,觸頭系統分上下兩層布置,上層有三對限流觸頭與限流電阻構成抑制涌流裝置。當合閘時它先接通經數毫秒之后工作觸頭接通,限流觸頭中永久磁塊在彈簧反作用下釋放,斷開限流電阻,使電容器正常工作。濾波電容器價格接線(xian)端(duan)有絕緣罩要蓋(gai)，安全(quan)可靠。線(xian)圈接線(xian)端(duan)帶有標出電(dian)壓(ya)數據,可防止接錯。

通常情況下，電氣設備不僅需要從電源獲取有功功率，而且還需要從電源獲取電力濾波電容器。如果電網中的(de)無(wu)功(gong)功(gong)率供應超過需(xu)求，則(ze)電氣(qi)設備(bei)(bei)將(jiang)(jiang)沒有足夠的(de)無(wu)功(gong)功(gong)率來建立正(zheng)常(chang)的(de)電磁場，這些電氣(qi)設備(bei)(bei)將(jiang)(jiang)無(wu)法在額定條件下運行，并(bing)且電氣(qi)設備(bei)(bei)的(de)端電壓將(jiang)(jiang)下降，這會影響電氣(qi)設備(bei)(bei)的(de)正(zheng)常(chang)運行。

電力濾波電容器中的(de)(de)投切開關(guan)(guan)(guan)具有特殊(shu)的(de)(de)電(dian)(dian)(dian)(dian)磁過(guo)(guo)零(ling)開關(guan)(guan)(guan)技(ji)術。 過(guo)(guo)零(ling)開關(guan)(guan)(guan)的(de)(de)偏移小(xiao)于2.5。 開關(guan)(guan)(guan)浪(lang)涌電(dian)(dian)(dian)(dian)流(liu)小(xiao)于額定電(dian)(dian)(dian)(dian)流(liu)的(de)(de)2.5倍(bei)。 智能(neng)控(kong)(kong)制單(dan)元通(tong)過(guo)(guo)在斷開開關(guan)(guan)(guan)的(de)(de)動(dong)態和靜態觸點時(shi)(shi)檢測(ce)兩端電(dian)(dian)(dian)(dian)壓來控(kong)(kong)制電(dian)(dian)(dian)(dian)壓的(de)(de)零(ling)交(jiao)叉點的(de)(de)閉(bi)合：通(tong)過(guo)(guo)在投切開關(guan)(guan)(guan)的(de)(de)動(dong)態和靜態觸點時(shi)(shi)檢測(ce)電(dian)(dian)(dian)(dian)流(liu)來控(kong)(kong)制電(dian)(dian)(dian)(dian)壓閉(bi)合時(shi)(shi)，控(kong)(kong)制其在電(dian)(dian)(dian)(dian)流(liu)的(de)(de)過(guo)(guo)零(ling)點處斷開以實現“過(guo)(guo)零(ling)開關(guan)(guan)(guan)”功(gong)能(neng)，使(shi)低(di)壓功(gong)率(lv)電(dian)(dian)(dian)(dian)容(rong)(rong)器投入運行時(shi)(shi)產生的(de)(de)浪(lang)涌電(dian)(dian)(dian)(dian)流(liu)很小(xiao)，并且沒(mei)有返回低(di)壓功(gong)率(lv)電(dian)(dian)(dian)(dian)容(rong)(rong)器時(shi)(shi)會產生電(dian)(dian)(dian)(dian)弧，從(cong)而延長了(le)低(di)壓功(gong)率(lv)電(dian)(dian)(dian)(dian)容(rong)(rong)器和開關(guan)(guan)(guan)設備本身的(de)(de)壽命，還(huan)減少(shao)了(le)開關(guan)(guan)(guan)設備接通(tong)和關(guan)(guan)(guan)閉(bi)時(shi)(shi)對電(dian)(dian)(dian)(dian)網(wang)的(de)(de)影(ying)響：提高了(le)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)電(dian)(dian)(dian)(dian)能(neng)質量。
