浅谈断路器电容器介质损耗问题

Brief Discussion on the Dielectric Loss of Circuit-breaker Capacitor

通过对断路器电容器特点及其损耗产生的分析 ,解释了断路器电容器常见的低场强下损耗角正切 tanδ易于偏大以及随着时间的增加 tanδ增长的现象 。

The analysis of the dielectric loss and characteristics of circuit breaker capacitor explains the reasons why the tangent of the loss angle (tanδ) tends to be big at low voltage, and why it increases with the voltage application time. Finally, the solutions are suggested.
