摘要
对大型水内冷发电机直流耐压试验和泄漏电流测试技术进行了探讨;阐述了大型水内冷发电机进行直流耐压试验和泄漏电流测试的具体方法、注意事项、影响测试准确性的因素以及对试验结果的分析判断;对发电机泄漏电流异常的常见原因进行了归纳总结,以供分析判断时参考。
The paper discusses the DC voltage endurance and current leakage test of large inner water cooling generators;describes the test in detail in terms of method,focal points,factors that influence the testing accuracy,and analysis of the testing results;and makes a summary of the common causes for abnormal current leakage of generators,which can be used as a reference for analysis.
