A generator is identical to a three-phase transformer. It has three live wires and one neutral wire. The connection between the three lights is 380 volts and the connection between the zero and the light is 220 volts.
Generators come in many forms, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
The neutral wire is a ground wire. In fact, there will be one buried in the ground at the power plant. When it arrives at its destination (usually the power transformer), we will run another wire up. floor. ThereNeutral line mentioned above uses the conductivity of the earth to save a line, which of course saves money. If a person stands on the ground and touches the neutral line, he will not feel any electricity, which is equivalent to touching an iron wire on a tree on the ground. 50 Hz means that the direction of current changes 50 times per second, that is, it flows from the live wire through the electrical appliance to the neutral wire, then from the neutral wire to the live wire. This alternating cycle counts for 50 cycles per second, which is very fast.
