摘要

在工程应用中

存在一套电容器装置包含多个电容器组并共用中性点的情况。文章以采用开口三角电压保护的装置为例分析了此类电容器装置的不平衡故障状态

建立了相应的计算模型

给出了不平衡电压保护的计算方法。结合实例与具有相同分组形式并与独立开关投切的电容器装置进行了比较

为今后工程实施提出了建议。

Abstract

In engineering application such case as multiple capacitor banks are included and neutral point is shared in a set of capacitor installation.The unbalanced fault condition of such capacitor installation is analyzed by the example of open delta voltage protection device

corresponding calculation model is set up and calculation method on the unbalanced voltage protection is given.The comparisons are made between such capacitor banks and other ones having the same grouping form but switched by independent switches

which provide suggestions for the project implementation in the future.
