摘要
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。
Electrical equipment of composite material has been applied in some substations,due to its characteristics of lighter quality and higher breaking strength. However,little research has been done in the seismic behavior of electrical equipment of composite material,especially for the experimental study of earthquake simulation shaking table. Based on the Sichuan-Tibet interconnection project,this paper summarized the researches on the seismic behavior of electrical equipment of composite material at home and abroad,and then studied its assessment method combined with the existing research on the seismic behavior of electrical equipment in China. Then,the input waveform,the peak acceleration and the judging principle of seismic ability also had been confirmed for the shaking table test of composite materials electric equipment. With using this method,800 k V HV reactor bushing,220 k V GIS external insulation bushing,110 k V and 220 k V lightning arresters were tested respectively on earthquake simulation shaking table,and the dynamic characteristics and seismic response of the equipment were obtained. The test results show that the stresses on the tested electrical equipments of composite material all meet the seismic requirements of 0. 4 g designed basic acceleration.
