摘要

本文研究环境温度与桥差保护电容器组不平衡电流的关系

首先分析温度对并联电容器的影响

通过试验得到不同电容器的温度系数

进而得到电容器温度系数的普遍规律

在此基础上

对桥差不平衡电容器组进行考虑温度因素的仿真分析

最后参考换流站实际运行情况

分析直流工程中桥差保护电容器组的不平衡电流与温度的关系。为直流工程中电容器组调平提供了参考。

Abstract

The relationship between ambient temperature and unbalanced current of bridge differential protection capacitor banks is studied in this paper. Firstly

the influence of temperature on shunt capacitors is analyzed

the temperature coefficients of different capacitors are obtained through test and then the general law of temperature coefficient of capacitors is obtained. On this basis

the simulation analysis of bridge differential unbalanced capacitor banks considering temperature factors is carried out. Finally

with reference to the actual operation of the converter station

the relationship between the unbalanced current and temperature of the bridge differential protection capacitor bank in DC engineering is analyzed.
