發那科電抗器介紹：電(dian)(dian)路(lu)中電(dian)(dian)抗(kang)器(qi)一般有兩(liang)個作用(yong)：①抑(yi)制(zhi)(zhi)浪(lang)(lang)涌（電(dian)(dian)壓、電(dian)(dian)流(liu)(liu)）；②抑(yi)制(zhi)(zhi)諧波電(dian)(dian)流(liu)(liu)。1. 抑(yi)制(zhi)(zhi)浪(lang)(lang)涌：在(zai)大(da)功(gong)率(lv)電(dian)(dian)力電(dian)(dian)子電(dian)(dian)路(lu)中，合閘瞬間，往(wang)(wang)往(wang)(wang)產生一個很大(da)的(de)(de)沖擊電(dian)(dian)流(liu)(liu)（浪(lang)(lang)涌電(dian)(dian)流(liu)(liu)），浪(lang)(lang)涌電(dian)(dian)流(liu)(liu)雖然作用(yong)時間短，但峰值卻很大(da)。比(bi)如，電(dian)(dian)弧爐(lu)、大(da)型軋鋼機，大(da)型開(kai)關電(dian)(dian)源(yuan)，UPS電(dian)(dian)源(yuan)，變(bian)頻(pin)器(qi)等，開(kai)機浪(lang)(lang)涌電(dian)(dian)流(liu)(liu)往(wang)(wang)往(wang)(wang)超過正(zheng)常工(gong)作電(dian)(dian)流(liu)(liu)的(de)(de)100倍以上(shang)。在(zai)輸入側串接電(dian)(dian)抗(kang)器(qi)，能(neng)有效的(de)(de)抑(yi)制(zhi)(zhi)這種(zhong)浪(lang)(lang)涌電(dian)(dian)流(liu)(liu)。『合閘瞬間，電(dian)(dian)抗(kang)器(qi)呈高阻(zu)態（相當于開(kai)路(lu)）』。2. 抑(yi)制(zhi)(zhi)諧波電(dian)(dian)流(liu)(liu)隨著電(dian)(dian)力電(dian)(dian)子技(ji)術(shu)的(de)(de)廣泛應用(yong)，我們的(de)(de)電(dian)(dian)網中增加了大(da)量的(de)(de)非(fei)線性負載，比(bi)如，AC－DC電(dian)(dian)源(yuan)，UPS，變(bian)頻(pin)器(qi)等，它們都是(shi)以開(kai)關方式工(gong)作的(de)(de)。這些以開(kai)關方式工(gong)作的(de)(de)用(yong)電(dian)(dian)設備(bei)，往(wang)(wang)往(wang)(wang)變(bian)成了諧波電(dian)(dian)流(liu)(liu)的(de)(de)發生源(yuan)，“污染"電(dian)(dian)網，使電(dian)(dian)網電(dian)(dian)壓波形(xing)畸變(bian)。諧波的(de)(de)危害之一便是(shi)中心(xin)線過載發熱燃燒。電(dian)(dian)抗(kang)器(qi)的(de)(de)接入，能(neng)有效抑(yi)制(zhi)(zhi)諧波污染。
