金属化聚丙烯膜交流电容器寿命评价
摘要
为了缩短金属化聚丙烯膜电容器耐久性试验时间
可以从提高电压和试验温度两方面来进行加速试验。提出了相应的寿命估算公式
两种应力的加速系数均为对应应力比值的幂指数。
Abstract
In order to cut down the metallized polypropylene film dielectric capacitor endurance test time
the accelerated test is used for increasing voltage and test temperature.The estimation formula of life expectancy is presented
the two kinds of stress acceleration factors are exponent index of the homologous stress ratios.
