受冲击液压装配式跨越架拉线优化布置研究

摘要

以一种新型液压装配式电网跨越架为研究对象,介绍了其结构和安装过程.结合常见的跨越架拉线布置方式,选取跨越架架体的拉线间距和拉线层数为主要设计要素.为了提高此类型跨越架架体的抗冲击能力,本文模拟计算了跨越架在发生电缆断裂事故后受的等效冲击载荷,研究了在等效冲载荷作用下两个设计要素改变时跨越架架体承载响应变化.针对这种类型跨越架的拉线布置提出优化建议,明显增强了其抗冲击性能.%This paper uses a new hydraulic power grid crossing as the research object and introduces its structure and installation process.Referring to widely used crossing's pulling layout,the pulling spacing and pulling layers are selected as the main design elements.In order to improve its impact resistance of the crossing frame,the paper simulates the crossing frame in cable cord equivalent impact in the cable breaking accident and studies crossing frame's bearing responding to the change of two design elements under the action of equivalent impact.The paper suggests the pulling layout optimization of this crossing,so as to enhance the impact resistance of the power grid assembled crossing.
