About fixed resistors in locomotive engines
Fixed resistors are electrical components designed to provide a specific amount of resistance to the flow of electric current. In locomotive engines, these resistors are typically used in the traction and braking systems.
In the traction system, fixed resistors are employed to control the amount of electric current supplied to the traction motors. By adjusting the resistance, the speed and torque of the locomotive can be effectively regulated. This is essential for maintaining optimal performance and ensuring smooth acceleration and deceleration.
In the braking system, fixed resistors are incorporated to dissipate excess electrical energy generated during regenerative braking. Regenerative braking is a process whereby the kinetic energy of the moving locomotive is converted into electrical energy and fed back into the power supply system. Fixed resistors provide a means to safely dissipate this excess energy, preventing damage to the locomotive and maintaining system stability.
