摘要
当风力达到一定程度后,会使城市轨道交通接触网产生巨大摆动和上下震动,造成接触线的技术状态发生急剧变化,以致影响列车的正常运行,发生弓网故障。分析了大风对接触网的影响,对接触网的设计风速取值、接触张力及其跨距、支柱选择、防风设计等内容进行了研究。提出接触网防风措施以提高接触网防风性能。
When the fresh gale achieves to a certain extent, it will cause the huge swing and up-down shake of URT overhead contact system, resulting in sharp changes of contact line technical state, affecting the normal train operation and even leading to the pantograph OCS fault. Through an analysis of the fresh gale effects on OCS, problems like contact tension, span, pillar selection and windproof design are studied. Measures to improve OCS windproof performance are proposed.
