摘要
为研究地震动输入共振拍波的频率与特高压电气设备频率不一致时对设备抗震性能评估结果产生的影响,通过理论分析与数值仿真,分析了共振拍波在特高压电气设备抗震试验中的局限性和不足之处。研究结果表明,特高压电气设备在地震作用下具有较强的非线性特征,试验过程中设备基频变化比较明显,选用共振拍波已不能达到与设备共振的目的。结合特高压电气设备的特点,提出了适用于特高压电气设备抗震试验的地震加速度反应谱,该反应谱的地震动力放大系数为2.5、特征周期为0.9 s,具有广泛的场地包络性,研究成果为特高压电气设备的抗震试验提供了依据。
In order to research the influences of equipment on the evaluation results of the seismic performance when the earthquake input resonance beat wave frequency is not consistent with equipment frequency, by theoretical analysis and simulation, we analyzed the limitations and inadequacies of resonance beat wave used in the seismic test of UHV electrical equipment. The research results indicate that resonance beat wave is not suitable for seismic test for UHV electrical equipment, this is mainly because UHV electrical equipment has strong nonlinear characteristics under earthquake, and the equipment's fundamental frequency changes significantly during the test, which means that using resonance beat wave can not reach the purpose of resonance. Combined with the characteristics of UHV electrical equipment, earthquake acceleration response spectrum which is suitable for UHV electrical equipment is proposed, of which the earthquake dynamic application coefficient is 2.5 and the characteristic period is 0.9 s. This response spectrum can envelope characteristic period of most sites. The research provides the basis for the seismic test of UHV electrical equipments.
