摘要
水轮发电机灭磁方式经历了线性常值电阻灭磁方式、自动灭磁开关的消弧栅灭磁方式和非线性电阻灭磁方式。对发电机的常值电阻灭磁方式、自动灭磁开关的消弧栅灭磁方式和非线性电阻灭磁方式进行了原理和性能分析,并与发电机理想灭磁的要求进行了比较,提出采用氧化锌非线性电阻灭磁装置灭磁的必要性。
Analyzes the principle and performance of generator magnetism erasing ways of constant resistance, automatic erasing switch with eliminating arc bar and non-linear resistance, compares with the ideal demand of generator magnetism erasing, puts forward the necessity of using zinc oxide non-linear resistance magnetism erasing device.
