摘　　要：简要介绍了电网存在的无功过剩问题以及并联电抗器在电网中的作用和发展应用情况。归纳总结近些年部分变电站的干式空心并联电抗器的故障类型,分析了产生故障的原因。针对故障原因探索性地提出了一种将感应线圈置于电抗器底部,通过感知感应电压变化来检测故障是否发生的监测方法。This article briefly introduces the surplus reactive power problems of power grid and the role of shunt reactor in power grid. It Introduces the development and application of shunt reactor and summarizes fault of dry-type air-core shunt reactors types in some substations recent years and analyzes the causes of fault. For the cause of the problem in exploratory put forward a solution which put the induction coil on the bottom of the reactor and through magnetic flux change induced voltage change detecting fault＇s occur.
