复合材料电气设备由于其具有质量小强度高的材料特点,已在部分变电站内推广应用,但对于复合材料电气设备的抗震性能,尤其对于其真型设备的地震模拟振动台的试验研究,各国学者研究较少。依托于川藏联网工程,在总结国内外复合材料电气设备抗震研究成果的基础上,结合我国已有电气设备抗震研究成果,开展了适用于复合材料电气设备抗震性能评估方法的研究,确定了复合材料电气设备振动台试验输入波形、波形峰值加速度以及设备抗震能力判定原则,采用此方法对800 k V高抗套管、220 k V GIS外绝缘套管、110 k V及220 k V避雷器分别进行地震模拟振动台试验,得到了设备的动力特性和地震响应。由试验结果可以看出,参与试验的复合材料电气设备应力均满足设计基本加速度为0.4 g的抗震要求。
Composite electrical equipment has been widely used in some substations due to its low mass and high strength material characteristics. However, for the seismic performance of composite electrical equipment, especially for the seismic research of its true equipment, Less research Based on the Sichuan-Tibet interconnection project, based on the summarization of the seismic research results of composite electrical equipment at home and abroad, combined with the seismic research results of existing electrical equipment in our country, the research on the seismic performance evaluation methods for composite electrical equipment is carried out. Materials Vibration table test input waveforms, peak waveform acceleration and equipment seismic principles determine the principle of using this method for 800 k V high anti-casing, 220 k V GIS outer bushing, 110 k V and 220 k V arrester respectively Earthquake simulation shaker test, got the dynamic characteristics of equipment and seismic response. It can be seen from the test results that the stress of the composite electrical equipment participating in the test meets the seismic requirements of designing a basic acceleration of 0.4 g.
