The invention provides a track circuit. The track circuit comprises a sending side and a receiving side, each of the transmitting side and the receiving side comprises a transmitting-receiving transformer, a lightning protection transformer, a transmission cable and a matching transformer; the transmitting-receiving device is connected with a steel rail through a transmitting-receiving transformer, a lightning protection transformer, a transmission cable and a matching transformer in sequence. The transmitting-receiving device in the transmitting side is a transmitting device, and the transmitting-receiving device in the receiving side is a receiving device; a resonance circuit is added on a line of a sending side and/or a receiving side; therefore, the power of the transmitting device is reduced, and only the signal strength in the section is enhanced; therefore, by adopting the track circuit provided by the invention, the power of the transmitting equipment of the track circuit can be reduced, the strength of the received signal can be improved, and in addition, the interference to the power frequency signal can be further weakened.
本发明提供一种轨道电路,包括:发送侧和接收侧;发送侧和接收侧均包括:收发变压器、防雷变压器、传输电缆、匹配变压器;收发装置依次通过收发变压器、防雷变压器、传输电缆和匹配变压器连接钢轨;发送侧中的收发装置为发送装置,接收侧中的收发装置为接收装置;在发送侧和/或接收侧的线路上增加谐振电路;以使降低发送装置功率,且只增强本区段内的信号强度;因此,采用本申请提供的轨道电路,可以降低轨道电路发送设备功率,还可提高接收信号的强度,另外对工频信号的干扰还能进一步削弱。
