摘要
Abstract
The failure is easily caused by the brittle fracture of semi-pantograph disconnector under the earthquake action. In this article, the experimental and numerical modal characteristics are analyzed and the response of dynamical time-history is investigated. The result shows that the resonance frequency of the equipment is close to the frequency of the earthquake wave. The porcelain column insulator and some joint positions can be easily destroyed under the earthquake action. The result provides the imperative data for improving the earthquake resistance of the equipment.关键词
