工(gong)廠無功補償(chang)元(yuan)器件如何有效治理諧(xie)波問題

將變(bian)(bian)頻器正確的(de)接(jie)(jie)地也對諧波治理有(you)(you)效，既可(ke)以使(shi)(shi)系統有(you)(you)效地抑制(zhi)外(wai)來干擾，又(you)能降低設備本身對外(wai)界(jie)的(de)干擾。當然，變(bian)(bian)頻器一定要使(shi)(shi)用(yong)專用(yong)接(jie)(jie)地線(xian)，且用(yong)粗短(duan)線(xian)接(jie)(jie)地。同(tong)時，盡量縮短(duan)線(xian)路長度，并(bing)將電源線(xian)和信號線(xian)單(dan)獨敷設，避(bi)免交叉(cha)；若是(shi)因條件限制(zhi)不能避(bi)免時，必須垂(chui)直交叉(cha)，不能平(ping)等敷設；信號線(xian)屏蔽層不接(jie)(jie)到電機或變(bian)(bian)頻器的(de)地，而應該(gai)接(jie)(jie)到控(kong)制(zhi)線(xian)路的(de)公(gong)共端。

可(ke)替代常規(gui)由熔絲、復合開(kai)關或機械(xie)式接(jie)(jie)觸器、熱繼電器、低(di)壓電力電容器、指示(shi)燈等散件在(zai)柜(ju)內和柜(ju)面由導(dao)線連接(jie)(jie)而(er)組成的自動無功(gong)(gong)補(bu)償(chang)裝(zhuang)置(zhi)。改變了傳(chuan)統無功(gong)(gong)補(bu)償(chang)裝(zhuang)置(zhi)體積(ji)龐(pang)大(da)和笨重的結構模式，具(ju)有補(bu)償(chang)效果更(geng)(geng)(geng)好，體積(ji)更(geng)(geng)(geng)小，功(gong)(gong)耗更(geng)(geng)(geng)低(di)，價格更(geng)(geng)(geng)廉，節約成本更(geng)(geng)(geng)多，使(shi)(shi)用更(geng)(geng)(geng)加靈活，維(wei)護更(geng)(geng)(geng)方便，使(shi)(shi)用壽命更(geng)(geng)(geng)長(chang)，可(ke)靠性更(geng)(geng)(geng)高(gao)的特點，適(shi)應了現代電網對無功(gong)(gong)補(bu)償(chang)的更(geng)(geng)(geng)高(gao)要(yao)求。
