110KV牵引变电所电气主接线设计高铁接触网的日常维护及其检修.doc

毕业设计（论文） 中文题目：高铁接触网的日常维护及其检修  中 文 摘 要 如今，高速铁路即反映也代表着一个国家的经济技术水平与综合国力，是当 今世界铁路发展的趋势和潮流。接触网主要由支柱与基础、支持装置、定位装置、 接触悬挂等四个部分组成，高速铁路和客运专线接触网是高速铁路牵引供电系统 和铁路客运专线的主体和关键。接触网系统也是牵引供电系统中主要的供电设备 之一，它直接与机车相连，当列车高速运行时，接触导线和机车受电弓之间是一 种动态稳定的关系，受流质量既取决于弓的参数，又取决于网的整体，两者参数 接触网是电气化铁路的重要组成部分，接触网的质量的优劣，将直接影响行车安全和运输经济效益，做好接触网的维修是确保接触网质量的重要手段。发生接触网设备事故后，供电部门的当务之急就是对其进行抢修，以最快的速度使其恢复供电。抢修人员到达事故现场后，面对破坏的设备，首先要解决的问题就是如何进行抢修作业的组织和怎样才能达到“先通后复”的要求。因而，从事接触网运行和检修的人员迫切需要对事故案例要有个分析和技术指导。应合理的匹配才能实现高质量的取流，才能确保列车高速运行。 关键字：高速铁路；接触网；维修； 英 文 摘 要 Nowadays, high speed railway that is reflected also represents a countrys economic and technological level and comprehensive national power, is the current world railroad development tendency and the tidal current. Contact net is mainly composed of the pillar and foundation, support device, positioning device, contact suspension consists of four parts, high speed railway and passenger dedicated railway contact net is the traction power supply system of high-speed railway and passenger dedicated railway line subject and key. Contact system of traction power supply system is the main power supply device, it is connected directly with the engine, when the train runs at high speed, and the locomotive pantograph contact wire is a kind of dynamic stability, the quality stream not only Yu Gongs parameters, and depends on the network as a whole, the two parameters. Contact network of electrified railway is the important part of the contact network, quality, will directly influence the traffic safety and carriage economic benefits, make contact net repair is to ensure the quality of the important means of contact network. Contact line equipment accident, the electricity sector is a pressing matter of the moment for the repair, with the fastest speed the recovery of power supply. Repair personnel arrived at the scene of the accident, the face of broken equipment, the first problem to be sol
