salient pole การใช้

• The underground power station generates power by two vertical units comprising Francis turbines and salient pole generators and has an installed capacity of.
• What type of generator is suitable ( asynchronous ) and what type of rotor ( squirrel-cage rotor, wound rotor, salient pole rotor or cylindrical rotor )?
• The generators are vertical shaft, salient pole, air cooled units each having 12 electromagnetic poles weighing 10 tonnes each, producing a terminal voltage of 18 kV, synchronous speed is 500 rpm.
• Within the Hawker Siddeley Group the company manufactured a vast range of electrical products including; turbo-generators, salient pole machines, induction motors, traction motors and generators, traction locomotives, switchgear, transformers and fuses.
• If a conventional squirrel-cage rotor has flats ground on it to create salient poles and increase reluctance, it will start conventionally, but will run synchronously, although it can provide only a modest torque at synchronous speed.
