摘　　要：地震灾害调查资料显示,电瓷型高压电气设备在电网工程中破坏严重。结合震后电网受损情况的调研,对电瓷型高压电气设备进行振动台试验及有限元分析,评价目前电力设施抗震设计标准的适用性,在技术经济合理的前提下,提出了在工程建设中切实可行的抗震措施,使其能更好地指导工程设计。同时,提出了提高电瓷型高压电气设备抗震能力的建议。It is shown from the investigation of earthquake damages that the porcelain high-voltage electrical equipment in the power grids engineering is seriously damaged after the earthquake.Based on an investigation of the power grid damages in an earthquake,shaking table tests and finite element analysis（FEA） are conducted of the porcelain high-voltage electrical equipment in order to assess the applicability of the existing aseismatic design standards for electric power establishment.On the precondition of technical and economic rationality,some applicable aseismatic measures are proposed for better guiding engineering design.In addition,some suggestions are also proposed on improving the aseismatic capabilities for porcelain high-voltage electrical equipment.
