The invention discloses a higher harmonic suppression device for ground signals and vehicle-mounted equipment, the higher harmonic suppression device is applied to a substation, a section post or a switching station of a traction power supply system of a railway system, and particularly comprises at least one filter circuit, a filter circuit is respectively arranged between a contact line of a power supply arm and a steel rail and between a positive feeder line and the steel rail in an AT power supply mode, and a filter circuit is arranged between the contact line of the power supply arm and the steel rail in a direct power supply mode. High-order harmonics on a loop between the contact line/positive feeder line and the steel rail can be filtered out through the filter circuit, and therefore the situation that due to the high-order harmonics, a track circuit receives voltage fluctuation or abnormal braking of a locomotive is caused is avoided.

    本申请公开了一种地面信号及车载设备的高次谐波抑制装置,该装置应用于铁路系统的牵引供电系统的变电所、分区所或开闭所,具体来说至少包括一个滤波电路,即在AT供电方式下在供电臂的接触线与钢轨之间和正馈线与钢轨之间分别设置一个滤波电路,在直接供电方式下在供电臂的接触线与钢轨之间设置一个滤波电路,通过滤波电路可以将接触线/正馈线与钢轨之间回路上的高次谐波予以滤除,这样就不会因为高次谐波而导致轨道电路接收电压波动或机车的异常制动。
