为研究影响变频电机用漆包线老化寿命的主要因素，采用不同规格的变频电机用漆包线作试样，对比研究了在不同脉冲电压上升时间下变频电机用漆包线的老化寿命。结果表明：在其它测试条件不变的情况下，试样电容值的变化会导致脉冲电压上升时间的变化，进而影响老化寿命；当脉冲上升时间加长时，击穿时间也延长；当脉冲上升时间缩短时，击穿时间也随之减少。

To study the main influence factors of the enameled wire’s ageing life for variable frequency motor, we used the different specifications of enameled wires to comparative study their ageing life under different pulse voltage rise time. The results show that the change of sample’s capacitance would result in the change of pulse voltage rise time and then affect its ageing life under the same test condi-tion. When the pulse rise time extends, the breakdown time prolongs; when the pulse rise time shortens, the breakdown time decreases.
