The insulation section is an important part of the track circuit and plays a great role in judging the position of the train and the electrical isolation of the track circuit signal. As high-speed railway continue to increase speed, maintaining the high-speed operation of the train will inevitably require a larger traction current. When the train passes through the insulation section, the large rail current will frequently appear to be briefly disconnected, and the arcing phenomenon will often occur between the wheel and rail. Due to the high traction rail current and overvoltage caused by the higher grade arc will burn the insulation section, resulting in damage to the insulation section, which will greatly affect the operation safety of the train when it is serious. Based on the “train-rail” circuit model constructed, this paper discusses that when the running speed of the train is 100km/h, the switch and resistance are connected in series between adjacent rails. Then the rail current when the train passes through the insulation section is reduced by controlling the resistance, so as to reduce the level of arcing, reduce the impact of current on the rail, and effectively ensure the safe and stable operation of the train.
