高压防爆同步电动机静态励磁调节装置故障分析及处理

Faults Analysis and Handle on Static State Excitation Regulation Device of High Voltage Ex Synchronous Motor

吐哈油田甲醇厂采用了两台功率为 330 0kW的正压通风型交流高压无刷励磁同步电动机、配套静态励磁装置 (WLK - 0 2H型 ) ,运行以来 ,同步电动机励磁装置曾出现故障 ,本文摘取其中较为典型的几例故障进行分析。

Two high voltage Ex ' p ' brushless excitation synchronous motor with static State excitation device,rated output is 3 300 kW (Type of WLK - 02H) are running in this plant. Several faults have been arisen in the excitation device of synchronous motor. Here,some typical faults are picked up for analyzing.
