6180KW DC1800 Ground Absorption Device Dynamic Braking Resistor

Product application:

In order to reduce the vehicle resistance equipment, inhibit the tunnel temperature rise, improve the
environmental effect, generally do not set in the car full power resistor braking device, but in order to ensure the regenerative braking of the grid voltage to maintain a certain range, generally used in the ground A certain distance between the set set of inverter absorber or resistance absorption device to absorb the excess energy generated when braking.
In the energy feedback system, when the inverter feedback device part of the capacity is limited, can no longer absorb the energy generated by the train regeneration brake, by putting the brake resistor device to
consume excess energy.

Features:

1. Effectively inhibit the temperature inside the subway, reduce vehicle equipment, reduce maintenance；
2. The whole device does not require the use of fans to reduce the dust inside the cave；
3. Can be intuitive to know the working status of the device；
4. The current application of more common programs at home and abroad, the program control is simple, reliable, mature application.

Product principles:

Ground absorption device acts as a power dissipation unit of the urban rail braking energy consuming device. When the locomotive is electrically braking, the traction motor works in the generator working condition, and the motor generates the counter-torque in the process of power generation to cause the train to decelerate.
When the electric energy is unable sent back to the grid, the braking resistor cabinet absorbs and dissipates the energy . Traction conditions, when the middle part of the DC voltage is too high, the excess energy needs to be released through the braking resistor.
