Braking resistors are made locomotive excitation regulator control

Wheel on the train through the kinetic energy into electrical energy consumed in the braking resistor, then the form of heat escaping into the atmosphere. In this process, generated by the traction motor shaft counter moment acting on the motorcycle wheel braking force generated on. The braking effect is called resistance braking.  electric transformer  diesel locomotives, most equipped with resistor braking devices. All Dongfeng diesel locomotive braking resistor circuit conditions substantially the same as the braking resistor are made locomotive excitation regulator (or resistor braking control cabinet) control, when the resistor  power transformers , the excitation regulator (or resistance brake control cabinet) according to the engine speed signal and provides the braking current and the magnetizing current  Voltage stabilizer  and actual braking current and excitation current is compared with a reference value by calculation, outputs a signal to control the chopper excitation current excitation system, the braking current and excitation current limit within a predetermined range.
