驼峰场雷达受牵引回流干扰问题解决方案探讨

Solution of Interference from Traction Return Current to Radar at Hump Yard

驼峰雷达受谐波干扰时会使测速数据不稳定,致使枢纽地区驼峰编组场较易发生车速控制不稳定,进而产生车辆超速或夹停的现象,影响运输安全.本文主要探讨枢纽地区驼峰雷达信号受供电牵引回流干扰影响测速的问题及其解决方案,为驼峰设计及施工提供指导.

Hump radar cannot give accurate speed measurement data stably due to harmonic in-terference,which leads to unstable car speed control of the hump marshaling yard at a hub sta-tion and even cause car over-speeding or stop,thus affecting the safety of transportation.There-fore,the influence of traction return current on hump radar signal at a hub area that may affect speed measurement is discussed and a solution is also given,offering a guide for the design and construction of hump yard.
