Where is the neutral line of the 380 V generator?

Notes:

Electric meter load can be adjusted with different Options. The inductance coil meets the usage requirements. For example, if an electric meter with a specification of 3x1(2)A is used with an inductor coil and the inductance coil ratio is selected as 1:50, the maximum current rating that each phase can carry is of 100 A.

In accordance with regulations, the neutral wire of the 380 V civil power supply must not be earthed at the input. If grounding is carried out on the transformer side, this grounding must take into account that the floating potential cannot cause a potential higher than the supply voltage. There is some resistance in the ground between the user side ground and the user side ground. the end of the transformer. The power method is a live wireion and a neutral wire, that is to say the conductive wire of the neutral point, forming a loop. There is also a ground wire connected to the single-phase, three-conductor power outlet.

How to connect the generator line of a gasoline engine? There are three lines on the generator. How should I connect it?

1 The electricity generated by the generator can be used directly, but if you use it for precision instruments, it is recommended to check whether the voltage and other parameters generated by the generator meet the equipment requirements. ;

2 Typically the generator has a star connection, with three-phase outgoing wires, what you call the live wire, and a center point wire, what you call the neutral wire;

3 It is recommended that the neutral wire of the generator be directly grounded to ensure: 1) The voltage of each phase of the live wire to ground is 220 V. Even ifone phase of the live wire is grounded. the ground voltage will not reach 380V to ensure the safety of people and equipment;

4 If the neutral line is not grounded, this does not mean that there is no voltage between the live wire and the ground. The tension still exists. You can try it with an electric meter.

5 If the neutral wire is not grounded, there is still capacitance between the circuit and ground. Therefore, when a person comes into contact with a live wire, a capacitive current flows through the person. If the generator capacity is small, the external circuit is short and the capacity is small, the capacitor current will be small and cannot cause personal accident. However, if the capacity is large enough, there will be personal danger;

6 If you touch the live wire,The live wire of the other phase is grounded and the voltagen on your body is 380V, just wait until you see God.

Whether it is a gasoline generator or a diesel generator, the principle and output of the generator are the same.

There are two sets of coils inside the generator. One is the excitation coil, also called the magnetic field coil, which is used to generate a magnetic field after being energized. The other is also the armature coil. called rotor, which is generated by rotating and cutting magnetic lines of force. The circuit diagram of the generator is as follows:

As shown in the circuit diagram, the output line of the generator has three terminals, namely the magnetic field terminal, the voltage output terminal and the earth wire. Terminal.

As shown in the figure, the magnetic field terminal should be connected to the magnetic field of the voltage regulator, and the voltage output is connected to the battery and electrical equipment.cudgel.
