摘要
分析了引起变频电机绝缘材料过早失效的主要因素,介绍了变频电机绝缘材料寿命评估检测设备的主要参数,提出标准定义中脉冲上升时间存在的问题,给出了脉冲电压上升率指标,指出在用示波器测试上升时间时应注意的问题,最后介绍了变频电机绝缘材料的寿命评估方法。
The main factors causing premature failure of insulating materials for inverter-fed motor were analyzed and the main parameters of life assessment testing equipment were stated.The problems in standard definition for pulse rise time were put forward and the pulse voltage rise rate index was given.The problems in using oscilloscope to test the rise time were pointed out and finally,the life assessment methods of inverter-fed motor insulating materials were presented.
