摘要

本文主要针对2串接线结构的电容器组固定框架电位的运行进行了研究。通过分析一起电解铝行业的电容器组损坏单元的解剖结果

以及运用ATP软件仿真验证固定电位接法导致电容器损坏的原因。发现固定框架电位会影响到非故障的电容器单元。阐述了这2种接线方式在绝缘配合上的优缺点和适用范围。

Abstract

In this paper

the operation of the fixed-potential rack of capacitor bank with two series wiring structure is mainly studied. The reason for the capacitor damage due to the fixed-potential is simulated and verified throughout disassembly result of the damaged capacitor bank from an aluminum industry company and with the use of ATP software. It is founded that potential of the fixed rack can affect healthy capacitor unit. Both the advantage and disadvantage of the two wiring methods in the insulation coordination and its scope of application is described.
