How to ensure electricity safety in the event of a typhoon?

As the typhoon rainy season approaches, you should pay attention to the following points to ensure the safety of electricity use:

1. Make arrangements in advance for the use of electricity for production and living, and pay. pay attention to electrical safety;

2. When water enters the house, the main switch should be turned off to avoid electric shock;

3. When you go out, don't go there. near flooded areas and try to avoid going near transformers, poles, street lights and other electrical equipment;

p>

4. If you find a fallen pole or broken power line, you should stay. move away immediately and call the 24-hour power supply hotline, 95598, to report it.

We hope that our answer will be useful to you.

(1)Cause: Wiring error.

Processing: Checkand 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 connection 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, thereby driving the engine. crankshaft to rotate.

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

Detailed information:

When the generator is connected to a symmetrical load, the armature winding The three-phase current in the motor 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 temporal phase difference between the no-load electromotive force E0 and the armature current I. TheArmature reaction magnetic field is also related 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 magnetizer. This will increase the output voltage of the generator.
