No power generation
The reasons of no power generation:
1. The voltmeter of the control panel is damaged or the wiring is in poor contact. This situation is generally after the diesel generator starts normally, and the voltage on the meter sometimes does not move. It is necessary to use a multimeter to measure the U, V, W, N phases of the motor, and the phases between U, V, and W. The voltage is about 400v, and the voltage between single-phase U, V, W and N is about 230v.
2. The air switch on the electric ball in the diesel generator is damaged: the phenomenon that occurs is that the diesel generator is normal when it is started, and it trips when the load is turned on.
3. Brushed motor equipped with diesel generator: The disadvantage of brushed motor is that demagnetization occurs occasionally, so it is necessary to keep 1-2 pairs of carbon brushes to prevent this situation.
4. The starting elements are not reached: the starting elements of diesel generators refer to the speed of 1500 rpm, frequency of 50HZ, and voltage of 400v. Many users feel that the noise of diesel generators will be very large when this data value is reached, so they reduce the speed by themselves. , the consequence is that the voltage is not enough, the frequency is not enough, and the power is not generated. After a long time, the power of the diesel generator will be insufficient.
5. Damage to the voltage regulating plate: The function of the voltage regulating plate is to adjust the excitation current correspondingly according to the change of the generator load, so as to maintain the terminal voltage as a given value, which can obviously smell the smell of burning.
The above are the common reasons for the failure of diesel generators to generate electricity summarized by our editor. We hereby suggest that if your diesel generator has not expired, please contact the diesel generator manufacturer to provide guidance on operation, and try not to repair it yourself.
