What are the reasons why the generator cannot produce electricity?

(1)Cause: wiring error.

Treatment: Check and correct according to the wiring diagram.

(2) Reason: The speed is too low.

Processing: Measure the rotation speed and keep it at the nominal value.

(3) Cause: There is mud or oxide on the wiring joint between the stator winding and the generator power distribution equipment, wiring screws are loose, the connecting wire is broken, and the stator winding is broken. .

Treatment: Use a multimeter or light test method to find out where the disconnection is. Check the connection and contact of each wiring screw.

Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thus driving the engine. crankshaft to rotate.

Instrunning the brushless synchronous alternator coaxially to the crankshaft of the electric machine, the rotation of the electric machine can be used to drive the generator rotor. Using the principle of "electromagnetic induction", the generator. will produce an induced electromotive force. The charging circuit can generate current.

Detailed information:

< p>When the generator is connected to a symmetrical load, the three-phase current in the armature winding will produce another rotating magnetic field, called the armature reaction magnetic field. Its speed is exactly equal to the speed of the rotor.

The armature reaction magnetic field and the excitation magnetic field of the synchronous generator rotor can be approximately considered to be distributed according to the sinusoidal law. The spatial phase difference between them depends on the pha differencee time between the no-load electromotive force E0 and the armature current I. The armature reaction magnetic field is also linked to the state of charge.

When the generator load is inductive, the armature reaction magnetic field acts as a demagnetizer, which will cause the generator voltage to decrease; when the load is capacitive, the armature reaction magnetic field acts as a demagnetizer; a magnetizer. This will increase the output voltage of the generator.

The following reasons can be considered for high generator temperature:

1. Poor ventilation system and significant blockage of vents. ;

2. The load is overloaded and the current is too large and the temperature rises;

3. The winding insulation is not qualified and the overall insulation level decreases;

4. The bearing is damaged or lack of oil, etc.
