官亭变电站750 kV高压并联电抗器运行状况分析

官亭变电站750 kV 2#电抗器是国内目前运行电压等级最高的一组高压并联电抗器。分析了750 kV高压电抗器在官亭变电站的运行情况和技术监督数据:技术监督数据稳定,油色谱分析数据良好,继电保护和安全自动装置无动作,电抗器整体运行状况良好。提出了未来改造计划:重新建造3台电抗器的基础,将目前的条形基础改为方形基础,增强电抗器的底部支持面,放弃现在使用的千斤顶;制造一台新的电抗器,替换运行中的电抗器B相。

Operating Analysis of Guanting Substation 750 kV Reactor

The 750 kV shunt reactor group running in Guanting substation has the highest voltage in China.This paper analyses the reactor group's operating situation and supervising data: the two-year data is stable;gas chromatographic analysis shows no abnormality;relay protection device do not start.All of these show that the reactor group is in good situation.The technique that modifies the reactor has been discussed: to rebuild the base of the reactors and change the base's shape from rectangle to square;and to manufacture a new reactor to replace the B phase of the reactor group.
