国内外大量变压器震害资料表明,降低变压器及套管体系的加速度响应是提高变压器及套管抗震能力的关键。针对变压器及套管体系的结构特点,提出变压器隔震设计的最低目标和3种有效的变压器隔震型式与布置方案,成功研制了变压器组合隔震支座并进行力学性能试验,并提出与变压器隔震设计相对应的验算指标。最后,结合四川220kV下孟变电站1#主变,开展变压器隔震技术的设计与应用。研究表明只要通过合理设计,变压器隔震技术可有效降低变压器及套管的地震响应,提高变压器的抗震能力。

Seismic damage data and experiences on power transformer at home and abroad indicate that reducing the acceleration response of transformer and bushings system is the key to improve the seismic capacity of the transformer and bushing. Considering the structural characteristics of transformer and bushing system, minimum targets and three effective layout program of isolation design on transformer are proposed. One combinational isolation beatings were successfully developed and the mechanical properties testing were completed. Checking targets according with isolation design are proposed. Finally, depending on No.1 main transformer of Xiameng 220 kV substations in Sichuan province of China, the design and application on seismic isolation technology for power transformer were carried out. It is concluded from above research that seismic isolation technology on transformer can effectively reduce the seismic response of transformer and bushing to improve the seismic capacity of the transformer on condition that seismic isolation design is rational.
