電力濾波電容器在改善(shan)供(gong)電(dian)(dian)(dian)系統(tong)(tong)中(zhong)電(dian)(dian)(dian)網的功率因(yin)數，減少供(gong)電(dian)(dian)(dian)變壓器和(he)輸電(dian)(dian)(dian)線路的損(sun)耗(hao)，提高供(gong)電(dian)(dian)(dian)效率以及改善(shan)供(gong)電(dian)(dian)(dian)環境(jing)方(fang)面發揮(hui)著作用(yong)。合理選擇(ze)補償(chang)裝置可(ke)以最大程度(du)地減少電(dian)(dian)(dian)網損(sun)耗(hao)，提高電(dian)(dian)(dian)網質量。相反，選擇(ze)或使(shi)用(yong)不當可(ke)能(neng)會(hui)導(dao)致許(xu)多因(yin)素，例如(ru)電(dian)(dian)(dian)源(yuan)系統(tong)(tong)，電(dian)(dian)(dian)壓波動和(he)諧(xie)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(jie)線端有絕緣罩要蓋，安(an)全可靠。線圈接(jie)線端帶(dai)有標出電壓數據,可防止接(jie)錯(cuo)。

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(dian)網(wang)中(zhong)的無功(gong)功(gong)率供應超過需求，則(ze)電(dian)氣(qi)設備(bei)將沒有足夠(gou)的無功(gong)功(gong)率來建立正(zheng)常(chang)(chang)的電(dian)磁(ci)場，這些電(dian)氣(qi)設備(bei)將無法在額定條件下運行(xing)，并且電(dian)氣(qi)設備(bei)的端(duan)電(dian)壓(ya)將下降，這會影響電(dian)氣(qi)設備(bei)的正(zheng)常(chang)(chang)運行(xing)。

電力濾波電容器中(zhong)的(de)(de)(de)(de)投切(qie)開(kai)(kai)關(guan)(guan)具有特殊的(de)(de)(de)(de)電(dian)(dian)(dian)磁過(guo)零(ling)開(kai)(kai)關(guan)(guan)技術。 過(guo)零(ling)開(kai)(kai)關(guan)(guan)的(de)(de)(de)(de)偏(pian)移小于2.5。 開(kai)(kai)關(guan)(guan)浪涌電(dian)(dian)(dian)流(liu)小于額定電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)2.5倍。 智能控(kong)制單元通過(guo)在斷(duan)開(kai)(kai)開(kai)(kai)關(guan)(guan)的(de)(de)(de)(de)動(dong)態和(he)(he)(he)(he)靜(jing)態觸(chu)點(dian)(dian)時(shi)(shi)(shi)檢(jian)測(ce)兩端電(dian)(dian)(dian)壓來(lai)控(kong)制電(dian)(dian)(dian)壓的(de)(de)(de)(de)零(ling)交叉點(dian)(dian)的(de)(de)(de)(de)閉(bi)合(he)(he)：通過(guo)在投切(qie)開(kai)(kai)關(guan)(guan)的(de)(de)(de)(de)動(dong)態和(he)(he)(he)(he)靜(jing)態觸(chu)點(dian)(dian)時(shi)(shi)(shi)檢(jian)測(ce)電(dian)(dian)(dian)流(liu)來(lai)控(kong)制電(dian)(dian)(dian)壓閉(bi)合(he)(he)時(shi)(shi)(shi)，控(kong)制其在電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)過(guo)零(ling)點(dian)(dian)處斷(duan)開(kai)(kai)以實(shi)現“過(guo)零(ling)開(kai)(kai)關(guan)(guan)”功(gong)能，使低壓功(gong)率電(dian)(dian)(dian)容器(qi)(qi)投入運行時(shi)(shi)(shi)產(chan)(chan)生的(de)(de)(de)(de)浪涌電(dian)(dian)(dian)流(liu)很小，并(bing)且沒有返回低壓功(gong)率電(dian)(dian)(dian)容器(qi)(qi)時(shi)(shi)(shi)會產(chan)(chan)生電(dian)(dian)(dian)弧，從而(er)延長了低壓功(gong)率電(dian)(dian)(dian)容器(qi)(qi)和(he)(he)(he)(he)開(kai)(kai)關(guan)(guan)設備本(ben)身的(de)(de)(de)(de)壽命，還減少了開(kai)(kai)關(guan)(guan)設備接通和(he)(he)(he)(he)關(guan)(guan)閉(bi)時(shi)(shi)(shi)對電(dian)(dian)(dian)網(wang)的(de)(de)(de)(de)影響：提(ti)高了電(dian)(dian)(dian)網(wang)的(de)(de)(de)(de)電(dian)(dian)(dian)能質量(liang)。
