摘要
利用反应谱法对±800k V电子式电流互感器进行抗震性能的可靠性分析,通过模态分析提取互感器前6阶振型进行分析,进而在8级烈度地震作用下,分析互感器传感头部分产生的最大位移,为软导线长度提供依据,同时验证了互感器整体结构强度满足8级烈度地震抗震要求。
Response spectrum method is used to analyze the seismic reliability of ±800 k V electronic current transformers.Modal analysis is used to obtain the first six mode of vibration. The maximum displacement of the sensing head under 8magnitude earthquake is analyzed to provide a basis for the length of flexible circuit conductor. The result indicates that the structural strength of the electronic current transformers can meet seismic requirements of level 8 magnitude earthquake.
