摘　　要：目前10～35 kV电容器组最常用的串联电抗器为干式空心结构,随着干式空心电抗器的广泛应用,其存在的各种问题也日渐暴露出来,事故的频繁发生对电网安全运行造成了一定的影响。本文结合典型的干式空心串联电抗器事故,从电抗器的设计、工艺及运行入手,对干式空心串联电抗器事故可能原因进行分析,并对电抗器安全运行的防护措施进行研究,总结了电抗器在设计、生产及运行阶段应注意的事项。At present, the most common series reactors for 10 -35 kV capacitor bank are of dry-type air-core structure. With wide application of dry-type air-core reactors, the existed various problems are exposed gradually and safe operation of the electric network is influenced by frequent occurrence of faults. In this paper, the possible reasons of fault for the air-core series reactor are analyzed based on the design, process and operation together with typical fault of dry-type air-core series reactor and the prevention measures on safe operation of reactor is studied. The precautions of reactor in the design, production and operation stages are summarized.
