摘要
针对同步发电机励磁系统中灭磁方式在更新改造中暴露出的可靠性问题,分析了几种常见灭磁方式的工作原理和优缺点及几种灭磁开关的特性,提出一种新的改进方法。
Due to the reliability problem appeared in renovating the excitation extingushing way for the synehro generator extitation system, the work principle of some general kinds of excitation extinguishing ways, their advantage ＆ disadvantage and the character on the excitation extinguishing switches are analyzed and a new improvement method is put forward too.
