摘要
采用氧化锌阀片取代灭磁回路中的灭磁电阻,发挥其良好的非线性及导通和截止功能,消除了灭磁回路因机械机构失灵造成转子回路危险过电压的可能性.灭磁回路结线简化,维护工作量少,运行可靠性增加,大大缩短了灭磁时间.
Using zinc oxide valve-disks instead of de-excitation resistance in the de-excitation circuit, taking its advantage of non-linearity and on-off function) can elimilate dangerous field over-voltage due to mechanical failure of contactor in de-excitation circuit. Simplification of de-excitation circuit leads to less maintenance higher reliablity and shorter de-excitation time.
