When braking subway, light rail, and tram vehicles, excess electrical energy is converted into heat energy for consumption, thereby achieving the goal of safe electric braking of the vehicles. Principle: When the electrical energy generated by electric braking of a vehicle cannot be stored or absorbed by the power grid, the chopper module is triggered to convert the electrical energy into thermal energy for dissipation by the braking resistor device.
Installation: Connected to the vehicle body through bolts, its external structure and installation method depend on the structural requirements of the host factory's vehicle body.
Connection: Braking resistor devices are generally used in main or auxiliary circuits, or can suppress instantaneous overvoltage caused by idling or pantograph jumping during traction and braking conditions.
