摘要
在水力发电公司检修时,几次碰到发电机不能启励建压的情况,经过检查分析,最终确定为剩磁的原因,主要是检修后剩磁的极性与转子直流电产生的极性相反造成的。针对剩磁原因造成不能启励的情况,提出相应的应对措施。
In the course of doing repair work for the Hydraulic Power Co., it occasioned several times that generator excitation could not get started. Checking and analysis revealed at last, that it was caused by residual magnetism after repair, the polarity of which was opposite to that effected by direct current in the rofor. Relevant remedial measures are proposed.
