The generator is three-phase and four-wire (three fires and one zero), and the distribution cabinet is three-phase and five-wire (three fires and one zero and one ground). After fire to fire and zero to zero, the electrical distribution cabinet ground wire is directly connected to the ground wire.
B is the +28V generator output, connected to the battery, and D+ is the low voltage 24. W is the center tap voltage of 13V (theoretically half of +B ), used for speed measurement or other relay power supply.
If the distribution cabinet and the generator are very close, the distribution cabinet and the generator must have ground lines common, that is, the generator shell, distribution cabinet shell and generator neutral line (neutral line) are all connected together. The distribution cabinet ground wire is drawn from the neutral line and metal. distribution cabinet shellution. No need to go to the generator to get it.
Main categories
Generator categories include:
Generators are divided into. : DC generators and alternators.
The alternator is divided into: synchronous generator and asynchronous generator (rarely used)
The alternator can also be divided into single-phase generator and three-phase generator. /p>
There are many types of generators. In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators. In terms of generation methods, they are divided into turbine and turbine generators. Hydraulic wheels. Generators, diesel generators, gasoline generators, etc. are divided into thermal generators, hydraulic generators, etc.
A light, zero and two wires are connected to the house. There is no distinction between neutral and live wires, and the ground wire is used toprotection. For example, if the generator produces electricity with a motor, the ground wire must be connected to the motor housing. Of course, there must be a space in between. The generator and the engine. The leakage protection switch, fire and zero of the generator should be connected to the leakage protection switch input interface. The generator ground wire cannot be used as a neutral wire. must be used in accordance with regulations. Otherwise it will be dangerous. If you do not connect ground to ground, it could charge the generator shell. p>
