接触网动态硬点是影响接触网,尤其是高速铁路接触网正常弓网关系的一项较为重要的因素,它会加快导线和受电弓滑板的异常磨耗和撞击性损害,破坏弓线间的正常接触和受流,并在硬点部位造成火花和拉弧。本文从多个方面分析接触网动态硬点形成的原因,并提出处理方案,为今后类似施工提高工程质量具有很好的指导作用。 The dynamic hard point of the catenary is a more important factor that affects the catenary of the catenary, especially the high-speed railway catenary. It will speed up the abnormal wear and impact damage of the cords and the pantograph, Normal contact and flow, and in the hard spot caused by sparks and arcs. This article analyzes the reasons for the formation of dynamic hard points in OCS from many aspects and puts forward the solutions to improve the quality of similar projects in the future.
