Power station is an electrical generating station. The energy
efficiency of a power station is usually called thermal efficiency and
may be defined as the electrical energy leaving the station divided by
the fuel energy entering the station. It is essentially a measure of the
overall fuel conversion efficiency for the electricity generation
process. The types of power station includes:
|
Helical gears - Are used to minimise noise and power losses.
Bevel gears - Used to change the axis of rotational motion.
Spur gears - Passes power from idler gears to the wheels.
Planetary gears - Used between internal combustion engine and an electric motor to transmit power.
