什么是串聯電抗器?

串聯(lian)電抗(kang)器是指一(yi)種由金屬導線繞制而成具(ju)有一(yi)定電(dian)(dian)(dian)抗值的電(dian)(dian)(dian)氣設備。它串聯于(yu)電(dian)(dian)(dian)氣回路(lu)上，主要(yao)用以限制短(duan)路(lu)電(dian)(dian)(dian)流。在(zai)城市電(dian)(dian)(dian)闡改造中，利用串聯電(dian)(dian)(dian)抗器(qi)限制短(duan)路(lu)容量，使一(yi)些斷流容量不足(zu)的繼路(lu)器(qi)可以繼續使用。一(yi)般用于(yu)35kV及以下電(dian)(dian)(dian)壓的電(dian)(dian)(dian)力系統中。
