The reasons why the Pacific Automotive Network alternator fault light is on are: the alternator is not synchronized; alternator temperature increases; the alternator stator winding is damaged; the alternator rotor winding is grounded; When the unbalance of the three-phase load of the generator exceeds the allowable value, the rotor temperature will also increase. At this time, the load should be reduced immediately and the system should be adjusted to reduce the imbalance of the three-phase load. that the rotor temperature falls within the permitted range.
Reasons the generator fault light is on include: the generator is not synchronized; generator temperature increases; the generator stator winding is damaged; the generator rotor winding is grounded.
Generator Failure Measures: 1. Whenhe generators are put in parallel using the quasi-synchronous method, they must meet the three conditions of same voltage, cycle and phase.
2. When the three-phase load unbalance of the generator exceeds the allowable value, the rotor temperature will also increase. At this time, the load should be reduced immediately and efforts should be made to adjust the temperature. system to reduce the imbalance of the three-phase load. Reduce the rotor temperature within the permitted range.
3. If you see a fire on the generator arc, the generator relay protection device will operate immediately, causing the main switch, field switch and emergency circuit breaker to trip, and the generator will shut down to function.
4. If the rotor's two-point grounding protection device is activated, its relay will also operate. At this time, the main circuit breakerThe generator must be shut off immediately to decouple the generator from the system. and stop, and at the same time turn off the de-excitation switch, set the magnetic field rheostat to the maximum resistance position, and check the rotor and excitation system after stopping.
