If the diesel generator set does not generate electricity after starting, it will delay the progress of other units and cause inconvenience to the power user. So, what is the cause of this common fault?
1. The ammeter indicated on the control panel is broken.
2. The "automatic-manual-demagnetization power" switch on the control panel is in the demagnetization position.
3. Incorrect wiring.
4. No residual magnetism or too low residual magnetism.
5. The motor carbon brush and collector ring are loose or the motor carbon brush spring pressure is insufficient.
6. The motor carbon brush grip is rusted or the carbon powder is stuck in the motor carbon brush so that the motor carbon brush cannot move up and down.
7. The rectifier two on the excitation regulator rectifier board has a tube lead or a freewheeling diode short circuit fault.
8. The rotating rectifier control module is damaged.
9. The diesel generator winding or the excitation regulator winding is disconnected or loose.
The above are the reasons why the diesel generator set does not generate electricity after starting. Before analyzing the reasons, it is also necessary for personnel to conduct proper inspections, accurately identify them, and then deal with them according to the corresponding reasons.
