摘　　要：特高压干式平波电抗器广泛应用在电力工程中,具有适应性好、方便运输、安装灵活等特点,能够抵抗恶劣天气的影响,长期在户外条件下运行。干式平波电抗器质量大、尺寸大、重心高,具有较高的地震易损性,是变电站直流输电工程中重要塔式设备,有必要对其抗震设计和评估进行深入研究。以典型布置的干式平波电抗器为研究对象,采用振型分解反应谱法进行地震反应分析,为实际工程中特高压干式平波电抗器的抗震设计评估及薄弱环节提供参考。UHV dry-type smoothing reactors are widely used in good adaptability,easy transportation,flexible installation,etc.They are able to resist the influence of bad weather and operate under outdoor conditions for a long time.With large mass,large size and high center of gravity,dry-type smoothing reactors have high seismic susceptibility and are important tower equipment in DC transmission projects of substations,which necessitates in-depth study of their seismic design and evaluation.Taking the typical arrangement of dry-type smoothing reactor as the research object,the seismic response analysis is carried out by using the vibration mode decomposition reaction spectrum method,which provides a reference for the seismic response analysis of UHV dry-type smoothing reactor and its weak points in the actual engineering.
