How is the generator output neutral line connected?

There are four wires coming out of the generator, which should be three live wires and one neutral wire. One end of the three live wires is the live wire and the other end is grounded with the neutral wire.

In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the volume decreases. the temperature rises rapidly, reaching the ignition point of diesel. The diesel ignites, the gas mixture burns violently and the volume increases rapidly, pushing the piston down.

Detailed information:

< p>The thrust on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thus causing the crankshaft to rotate. By installing the brushless synchronous alternator coaxially to the crankshaft 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 induced electromotive force. and a current can be generated through the closed charging loop.

After starting, it should run at low speed for 3-5 minutes. The operation can only be started after the oil temperature and pressure are normal. There should be no abnormal noise when the generator increases in speed, the slip ring and commutator brushes should be in good contact, and there should be no jumps or sparks. After the operation is stable and the frequency and voltage reach the rated values, power can be supplied externally.

This is an altethree-phase generator. Use a multimeter to measure it. 4 binding terminal resistors can be used to distinguish which one is the neutral wire (the red test lead is connected to the neutral wire, and the black test lead measures the same resistance value of the other three wires, then the red test lead is the neutral wire, and the other three are live wires.) There are two connection methods: one is to use a live wire and a neutral wire to connect a diode for charging the 12 volt battery; involves using three live wires to connect the three-phase bridge rectifier to a 12-volt DC output to charge the battery.

In addition, you can also use a live wire and a neutral wire to directly connect the car headlights for lighting purposes.
