The process by which a car generator generates electricity is as follows:
1. Before you start, check whether there is enough oil in the fuel tank and whether there are any oil leaks. in every oil pipe and joint; cooling; Whether the water in the system is sufficient, clean, and leak-free, and whether the fan belt is properly tightened. Check that the transmission parts of the internal combustion engine and generator should be reliably connected, the output line wires should be well insulated, and all instruments should be complete and efficient.
2. 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 accelerates, the slip ring and commutator brushes should be ingood 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.
3. When abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting.
4. The generator power factor should not exceed late phase (lag) 0.95. The variation range of the frequency value should not exceed 0.5 Hz.
5. Before stopping, you must first turn off the main switches of each power branch, gradually reduce the load, then turn off the main power switch of the generator and return the excitation rheostat to the maximum resistance position to reduce the voltage to the minimum value, thencut off the excitation switch and the neutral point grounding switch, and finally stop the operation of the internal combustion engine.
