一种高速列车车载接触网激光除障系统的设计

Design of A High-speed Train Carried Laser Removal System for OCS

接触网是高速铁路牵引供电系统的薄弱环节,易遭受树枝、轻飘异物等侵扰,导致变电所跳闸,影响弓网受流,甚至导致塌网事故,影响列车安全正点运行。本文以激光除障技术为研究对象,通过对比现有激光技术和计算接触网温度场模型,提出了一种高速列车车载激光除障系统,可以在列车行驶过程中及时清除挂网异物并发出预警,具有一定的应用价值。

The overhead contact line system(OCS)is a weak link in the traction power supply system of high-speed railway,and it is prone to be interfered from the tree branches,floating foreign objects,etc.,leading to substation tripping,affecting the current collection of the pantograph-catenary system,and even leading to accidents of catenary collapse,interfering the safe and punctual operation of trains.The paper,taking the obstacle removal technology as the research object,by comparing of existing laser technologies and calculating of OCS temperature field model,puts forward a high-speed train carried laser obstacle removal system.It is able to remove the foreign objects attached on OCS and send out pre-warning alarm during train running process,and it has a certain application value.
