In high-speed and heavy-load operation environment, the insulation joints of the station track circuit are damaged in many stations, which caused the carrier information of the adjacent sections to interfere with each other, endangered the safety of the train and reduced the reliability of the track circuit. In order to solve the incorrect code problem caused by the insulation joint breakage, we analysed the insulation damage situation for the station track circuit and the structural principle of BES choke transformer. Then the different structures of the insulation damage protection circuit are given and the relevant parameters are obtained, and verifying the anti-interference ability of the new BES choke transformer. Finally, a complete four-terminal network model of the new BES choke transformer is established. And its four-terminal network parameters are calculated by matlab simulation, which provides the theoretical basis for establishing the track circuit complete system.
