湖北发电机组

灭磁电阻的作用:发电机的励磁绕组就是一个具有较大电感的线圈,在正常情况下,励磁电流在发电机转子上产生较强的磁场。当发电机内部故障时,需要迅速切断励磁电流,除去发电机的磁场,以免事故扩大。但是,用开关直接切断这种具有较大电感的电路中的电流是很困难的。因为直接切断励磁电流会在励磁绕组的两端产生高电压,可能烧坏开关触头。因此,在切断励磁回路前,首先在转子两端并联接入灭磁电阻,这样再切断励磁回路时,灭磁电阻就可迅速吸收励磁绕阻的磁能,减缓转子电流变化速度,达到降低转子自感电动势,起到抑制转子过电压和灭磁的目的。

直流灭磁:常规磁场断路器一般都串联在励磁直流回路中,目前国内大部分新建机组及老机组改造都选择灭磁开关配合ZnO 非线性电阻的灭磁方案。
