DIESEL ELECTRIC LOCOMOTIVEDYNAMIC BRAKE HATCH ASSEMBLY
For WDG4/WDP4 EMD*** locomotives DU100101010
The Dynamic Brake Hatch assembly is mounted in the long hood frame of the high horse power Locomotives, 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 operate 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.
