摘要

对汶川地震和我国以往的几次大地震中电网设备损坏较为严重的电瓷型高压设备——220kV绝缘子及避雷器进行振动试验研究,测定其在不同地震作用下关键部位的加速度、应变等主要参数,以此来分析电瓷型高压设备结构的动力特性、抗震性能以及设备支架和上部设备连接处的受力性能,并为综合评定结构的抗震性能和结构设计方法提供参考。
Vibration test study has been carried out on the HV electro ceramic equipment,i.e.the 220 kV insulators and the lightening arrester,which are often found seriously damaged in the Wenchuan Earthquake and the other major earthquakes that previously took place in China.Major parameters such as the acceleration of the key parts and the strain of the equipment are measured under different earthquake wave conditions.These parameters are used to analyze the dynamic characteristics,anti-seismic performance of the equipment as well as the load-carrying capacity of the bracing at the joints with the equipment above.This study is aimed at providing reference for comprehensive evaluation of the anti-seismic performance of the equipment structure and its structure design.
