摘要
地震给电力设备带来严重破坏,需要加强对电力设备抗震性能方面的研究。根据GB50260-1996电力设备抗震设计规范,阐述了振型分解反应谱理论计算电力设备地震响应的基本内容及步骤,结合500kV电流互感器抗震性能评估的工程实例,应用强度破坏准则对模型进行了抗震性能验算。结果表明,该互感器可满足抗震设防烈度为9度地区的使用要求;根据危险断面出现位置,给出提高抗震性能的几点措施,可为其他电力设备抗震性能优化提供参考。
The heavy seismic damage to the electrical equipment has been brought,it is necessary to study the seismic performance of electrical equipment.According to the GB 50260-1996 Code for seismic design of electrical installations,the basic contents and steps of seismic response analysis for the electrical equipment calculation by mode decomposition and response spectrum theory are described.The seismic performance of 500kV current transformer is analyzed by using material strength failure criterion.The results show that the 500kV current transformer is able to satisfy the serviceability requirement in seismic intensity 9 regions.According to the position of danger section,several measures to improve the seismic performance of the current transformer are put forward,which could be for reference of seismic design for other electrical equipments.
