What is the reason why a hydroelectric generator switches to electric motor operation?

Introduction What is the reason why a hydroelectric generator switches to electric motor operation? According to the law of energy conversion, electrical energy is generated through the principle of cutting magnetic field lines. This is the principle of the generator.

What is the reason why a hydroelectric generator switches to electric motor operation?

According to the law of energy conversion, electrical energy is generated through the principle of cutting magnetic induction lines. This is the principle of the generator. Water at high altitudes flows downward due to the earth's gravity. The force of the flow is called gravitational potential energy. Gravitational potential energy causes the generator blades to conduct mechanical energy to the generator so that it rotates and generates electrical energy. the coils cutting the magnetic induction lines. The generator itself can also be used as an electrical device when electricity passes through it, it converts electrical energy into mechanical energy and rotates it.

Generators are generally composed of stators, rotors, end covers, bearings and other components.

The stator consists of the stator core, wire windings, machine base and other structural partsurelles that secure these parts.

The rotor is composed of a rotor core winding (or magnetic pole, magnetic yoke), retaining ring, center ring, slip ring, a fan and a rotating shaft.

There are many types of generators. In terms of energy, they are divided into thermal generators, hydraulic generators, etc. ; In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators. In terms of generation method, they are divided into steam turbine generators, hydraulic generators, diesel generators, gasoline generators, etc.

The working principle is that the stator and rotor of the generator are connected and assembled by the bearings and end covers, so that the rotor can rotate in the stator and carry out the cutting movement magnetic lines of force. , thus generating a mateinduced electrical current, which passes through the terminals. When removed and connected in the loop, a current is generated.
