串联电容器装置保护的可靠性分析

Reliability Analysis of Series Capacitor Protection Devices

介绍串联补偿装置的发展状况,对其基本结构、接线方式、不平衡保护计算进行探讨。对比无熔丝电容器和内熔丝电容器的结构、性能差异,分析2种电容器的适用性以及在串联电容器装置中使用时的可靠性,提出提高保护可靠性的方法。

In this paper,the development situation of series compensation devices is described. The basic structures,the connection modes,and the calculation ways of unbalance protection are discussed. The comparison of the structure and the performance differences between the capacitors with and without internal fuses are made. Meanwhile,the applicability of the two kinds of capacitors and the application reliability in series compensation capacitor devices are also analyzed. Finally,the way to improve the reliability is presented.
