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 generator and alternator.
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.
How to connect a three-phase generator to three single-phase motors. What is the best wiring method? Is it better to use quatre wires or just one live wire and one neutral wire?
A wire, zero wire, and two wires are connected to the house, regardless of the wiring type? the neutral wire, the live wire and the earth wire. It's for protection. For example, if a generator produces electricity with a motor, the ground wire must be connected to the motor housing. Of course, there must be a leakage protection switch. between the generator and the engine. The zero line should be connected to the input interface of the leakage protection switch. The generator ground wire cannot be used as a neutral line. Any high voltage electrical element must be used in accordance with regulations. Otherwise, it's dangerous. If you connect one, zero and one ground there will be no voltage, do not connect the fire to the house, this may charge the generator shell! >Consider load balance and efficient use of energygenerator bearing to reduce the single voltage of the generator. The winding load
All four wires are used
Each of the. the three live wires are connected to a motor with the zero wire (neutral wire),
9KW The output can only be obtained when the load of the three-phase four-wire system is balanced if you. use only one light and one zero, you only use one of the phase power windings. It can only provide a maximum of 3 kW, which means it can drive a 3 kW single-phase motor at the moment. , one must be connected to each phase, and one winding corresponds to one motor, so that a single winding is not burned due to overload.
