集合式电容器差压保护动作原因分析

摘要

Aiming at a35 kV assembly capacitors differential pressure protection action accident, this paper analyzed that the dam-age of capacitor element was the cause of capacitor differential pressure protection action. Combined with this accident analysis, this paper introduced the principle, the structure and the action accident analysis method of assembly capacitors differential pressure pro-tection, and raised measurement and acceptance examination actual suggestions for assembly capacitors.%　　针对一起35 kV电容器组差压保护动作事故，分析了电容器差压保护动作的原因是电容器内部元件受损导致的。结合此次事故分析，介绍了集合式电容器差压保护的原理、集合式电容器结构以及集合式电容器差压保护动作事故分析方法，并对集合式电容器的测量与交接验收提出了具体建议。
