电机长期过载运行,受潮,定转子相擦引起的局部过热都可能导致绝缘性能降低、老化,发脆而起接地故筛障。因此在实际工作中,我们常常检测电机的绝缘电阻,用来衡量电机绕组和绝缘情况是否符合规定的要求,以保证电机的安全使用。究竟如何检测,检测出来的电阻值相对于规定要求的电阻 Long-term overload motor operation, damp, due to local rotor friction caused by local overheating may result in reduced insulation properties, aging, brittle and ground from the screen so the screen barrier. Therefore, in actual work, we often check the motor insulation resistance, used to measure the motor windings and insulation meet the requirements of the regulations to ensure the safe use of the motor. How to detect, detect the resistance value relative to the required resistance
