浅谈绝缘电阻测量分析与提高的措施

Analysis and Improvement Measures for Insulation Resistance Measurement

绝缘电阻是电气设备重要的电气性能之一。绝缘电阻的正确测量和测量结果判断分析,直接影响电气设备的安全稳定运行。本篇文章从测量方法和注意事项入手,详细论述了绝缘电阻测量的影响因素,作者以自己在变电所测量绝缘电阻为例,讲述了测量结果的判断分析,并提出了现场设备提高电气设备绝缘电阻的措施。

Insulation resistance is one of the important electrical properties of electrical equipment.The correct measurement of insulation resistance and the judgment and analysis of measurement results directly affect the safe and stable operation of electrical equipment.This article starts with measurement methods and precautions,and discusses in detail the influencing factors of insulation resistance measurement.The author takes his own measure-ment of insulation resistance in a substation as an example,explains the judgment and analysis of measurement re-sults,and proposes measures to improve the insulation resistance of electrical equipment on site.
