摘要

对于应用在发电机保护断路器成套装置中的电容器

要求其长期运行在较高环境温度下。笔者从提高电容器使用温度的角度

对聚丙烯膜浸渍苄基甲苯电力电容器进行了高温条件下的老化试验和过载试验研究

分析了提高全膜电容器使用温度的可能性及极限温度

认为该介质结构的电力电容器在心子温升不超过10℃时

可连续运行在80℃高温环境中。

Abstract

For the power capacitor

used in the circuit breaker complete set for the generator protection

it is always required to operate in higher ambient temperature for a long time.From the perspective of increasing the capacitor’s operating temperature

the aging test and overload test of power capacitor of Benzyl toluene impregnated polypropylene film is studied

the maximum temperature and possibility of increasing the operation temperature of all-film capacitor is analyzed.The results show that power capacitor of this structure can run continuously at 80 ℃ high temperature when the temperature rise of the core is limited no more than 10 ℃.
