摘要
接触网张力补偿装置作为接触网关键设备之一,是保证接触网可靠受流、安全运行的重要保障。文章基于高原铁路青藏铁路格拉段的强震、大风和高温差等复杂环境和气候条件,对比分析了常用张力补偿装置的适应性、可靠性,推荐选用弹簧补偿装置,通过有限元方法对接触网受温度变化影响后的跨中形变和弹簧伸缩进行定量分析,满足标准要求,从而验证了弹簧补偿装置的高原铁路适应性。
As one of the key equipment of the contact network,the tension compensation device of the contact network is an important guarantee for ensuring the reliable current collection and safe operation of the contact network.This article compares and analyzes the adaptability and reliability of commonly used tension compensation devices based on complex environmental and climatic conditions such as strong earthquakes,strong winds,and high temperature differences in the Gola section of the Qinghai Tibet Railway on the plateau railway.It is recommended to use spring compensation devices.Through finite element method,quantitative analysis is conducted on the mid span deformation and spring expansion of the contact network after temperature changes,meeting the standard requirements,and thus verifying the adaptability of spring compensation devices on the plateau railway.
