摘要

采用树脂封装成型的电力电子金属化电容器具有重量轻、极壳绝缘强度高、安装方便等特点

但内部材料在温度变化时由于膨胀系数不同而导致体积变化

进而造成壳体开裂以及在潮湿条件下可能发生水气浸入电容器内部等质量问题

因此需对其机械性能和承受环境应力的能力需要进行验证考核。本文根据相关标准、使用条件和树脂封装成型电容器的参数要求及薄弱环节确定了多项参数加严和特定试验项目

用于验证此种电容器能否满足轨道交通的使用要求。最后通过试验验证了树脂封装成型电容器的可靠性。

Abstract

Power electronic metallization capacitor formed by resin encapsulation has such features as light weight

high insulation strength of case and convenient installation.However

the volume is changed due to different expansion coefficient in case of temperature variation of internal material in the temperature variation

thus causing such quality problem as case breakage and moisture penetration into capacitor in the wet and humid condition

therefore its mechanical performance and ability to withstand environmental stress shall be verified and checked.In this paper

multiple parameters and specific test items are defined in accordance with related standards

service condition

and the parameter requirement of re sin enc apsulated forming capacitor as well as weak points

which is used for verifying whether such capacitor can meet application in rail transportation.Finally

the reliability of the resin enc apsulated c apacitors is verified by the tests.
