摘　　要：为研究我国电力设备抗震设计规范中关于电气设备动力反应放大系数条款的适用性,以美国变电站抗震设计推荐实施规程(IEEE 693—2005)、日本电气设备抗震设计指南(JEAG 5003—1980)和中国电力设施抗震设计规范(GB 50260—1996)为研究对象,从规范的适用条件、参数取值和影响因素等方面,综合对比美、中、日三国规范电气设备动力反应放大系数选取时的异同点,通过选用几种具有代表性的电气设备作为算例,利用有限元软件对其进行时程分析。研究结果表明:对于自振频率较低、自身重量较大的电气设备,可按我国电力设施抗震设计规范的要求进行设计;而对于自振频率较高,重量较小的电气设备,我国GB 50260—1996相应条款的适用性则有待进一步商榷。结合国外先进的抗震设计理论,提出完善我国相关电气设备动力反应放大系数规范条款的修订建议。In order to study the applicability of Chinese code of dynamic response magnification factors for high-voltage electric equipment,based on the IEEE recommended practice for seismic design of substations(IEEE 693—2005),Japan Electric Association Guideline for a seismic measures in electrical facilities(JEAG 5003—1980) and Chinese code for seismic design of electrical facilities(GB 50260—1996),the differences of relevant codes of the dynamic response magnification factors for electrical equipment between those three countries were compared from aspects of applicable conditions,parameters assignment and influence factors,etc.Then use the finite elements methodology to analysis certain typical electrical equipments.The result shows that the electrical equipment with lower frequency and larger weight should be designed comply with the GB 50260—1996;on the contrary,the applicability of GB 50260—1996 to the electrical equipment with higher frequency and lighter weight should be remain considering.In summary,referencing to the foreign advanced seismic design theory,propose relevant suggestions to improve the terms of the Chinese code of the dynamic response magnification factors for electric equipment.
