我国第一套超高压单相并联电抗器组十四年运行的回顾

Review of Fourteen Years of Operation of the First Ultrahigh Voltage Single-Phase Shunt Reactors in China

我国第一组330千伏单相并联电抗器于1975年4月在甘肃省秦安变电站投入运行。本文以十四年运行中发生的几次典型的恶性未遂事故为例,介绍了电抗器故障的发现和处理经过。文中揭示了电抗器设计和制造中的缺陷和问题,介绍了一些取得成效的改进措施,并对气相色谱分析在监视电抗器安全运行中的重要作用做出了肯定的评价。本文为超高压并联电抗器的设计、制造、维护和检修工作提供了可贵的经验。

This paper introduces the processes and the measures of detecting and handling of reactor faults, for instance first ultra-high voltage single-phase shunt reactors during the fourteen years opration, indicates problems of designing and manufacturing of reactors, introduces some effective improving measure. It is affirmed that the vapor phase charomutography plays an important role in supervising security opration of reactors. This paper provided valuable experience for design, manufaction, maintenance and overhauling of ultrahigh voltage shunt reactors.
