摘要: 针对高压电流互感器抗震能力较为薄弱的问题,以某型电流互感器为研究对象,开展其抗震及减震性能分析研究,旨在确保高压电流互感器在地震发生时的无破坏性。文中基于ANSYS开展电流互感器模态分析研究,获得电流互感器的固有频率和模态振型,确定电流互感器易损坏的部位;根据美国变电站抗震设计推荐规程IEEE Std-693-2005和高压开关设备抗地震性能试验GB/T13540-2009要求,选用天然Elcentro波和Taft波对高压电流互感器进行水平激励,开展易损坏部位的位移和应力时程分析,确定其最大位移和最大应力,为电流互感器的抗震设计优化提供技术支撑。
Abstract: According to the weak character of seismic capacity of high voltage current transformer and en-suring no damage at the time of the earthquake, the current transformer is used as research object to carry out the aseismic capacity and seismic isolation analysis. Firstly, the modal analysis of high voltage current transformer is carried out, and the natural frequency and mode shape of the breaker are calculated, and the easily damaged parts of high voltage current transformer are determined. Secondly, according to the standards of the IEEE Std-693-2005 and GB/T13540-92, natural El-centro wave and Taft wave are used to carry out the level excitation of the high voltage current transformer, and the time history analysis of the displacement and stress of the vulnerable parts of current transformer is carried out, and the maximum displacement and maximum stress of vulnerable parts are determined. The above research can provide technical support for the seismic design optimization of the current transformer.
