摘要
重点介绍美国IEEE Std 693-2005、IEC系列标准和我国电气设备抗震规范的基本情况后,从抗震设防目标、设防水准、场地类别、抗震设计反应谱、安装方式、抗震措施和抗震能力要求等方面对比分析了电气设备抗震设计技术的差异,指出我国规范中设计的不足。通过对比研究美欧先进的电气设备抗震设防标准,提出了改进我国电气设备抗震设计规范修订的建议。建议我国应适度提高电气设备抗震设防目标和设防水准、重新考虑阶梯跳跃变化的场地分类方案,修正设计反应谱的特征周期和反应谱值,以及提高我国电气设施抗震设计的措施等,提高我国电气设备的抗震能力。
It was put emphasis on introducing the basic information of IEEE Std 693-2005 of USA,IEC standard and China’s code for seismic design of electrical installations,and comparing the difference of seismic design technologies of electrical equipment in aspects of precautionary objectives,seismic qualification levels,site class definitions,the required response spectrum,mounting,seismic measures and seismic qualification among the above three standards,and it pointed out the shortcomings in seismic design in our country. Through comparative study on the advanced seismic precautionary standards for electrical equipment of USA and Europe,this paper put forward some suggestions on our country’s seismic design improvement and standard revision. It was suggested that China should improve the seismic precautionary objectives and seismic qualification levels of electrical equipment,reconsider the site classification scheme of terraced jump variations,modify the design characteristic periods of ground motion and response spectrum values of design response spectra,and improve the measures of seismic design of electrical installations to improve the seismic capability of electrical equipment in our country.
