The
Dynamic Brake Hatch assembly is mounted in the long hood frame of the
EMD Locomotives manufactured by Indian Railways, which consists of a
eight grid resistor boxes, two blowers powered by two direct current
series motors, cable assemblies and other accessories.
The
Dynamic Brake is used to control the speed of the train on a
continuous down gradient as well as on level section. When the
locomotive is operating in dynamic braking, the traction motors
operates as generators. The electrical power generated by the
traction motor is converted into heat in braking grids. This heat is
dissipated into the atmosphere by the dynamic brake fan and motor
assembly.
The
Dynamic Brake grid motor is powered by a portion of the electricity
generated by the traction motors during dynamic braking operation. |
