Insufficient or impure fuel: Diesel generators generate electricity by converting the energy released during fuel combustion into electrical energy. If the fuel is insufficient or impure, it will cause the diesel generator to fail to generate electricity normally.
Insufficient combustion: During the combustion process of diesel generators, a certain temperature and pressure are required to achieve complete combustion and release more energy. If the combustion is not sufficient, it will lead to insufficient power generation of the diesel generator, or even no power generation at all.
Mechanical damage: Diesel generators may experience some mechanical damage during use due to prolonged wear and tear or improper maintenance. Such damage may cause the generator to not rotate or result in low power generation efficiency.
Excitation issues: including the magnetic pole material of the exciter being close to soft steel, with small residual magnetism, and the magnetic field disappearing when there is no current in the excitation winding after shutdown; The magnetic poles of the generator lose their magnetism; The excitation circuit components are damaged or there are open circuits, short circuits, or grounding phenomena in the circuit; Poor contact between the excitation machine brush and the commutator or insufficient pressure on the brush holder; Incorrect wiring of excitation winding, opposite polarity, etc.
Line connection issues: including poor contact between the generator brush and slip ring, or insufficient brush pressure; Generator stator winding or rotor winding open circuit; Loose wiring of the generator lead or poor switch contact, etc.
For the above reasons, the following solutions can be taken:
Ensure fuel quality and supply: Use pure fuel and add enough fuel in a timely manner to avoid situations of insufficient or impure fuel.
Maintain sufficient combustion: Regularly inspect and maintain the combustion system of the diesel generator to ensure that the operating temperature and pressure are within the appropriate range.
Regular inspection and maintenance of mechanical components: Regularly inspect the wear and tear of mechanical components, and promptly replace and maintain damaged parts.
Resolve excitation issues: Inspect and repair the excitation system to ensure its proper functioning. Check the contact between the excitation machine brush and the commutator to ensure sufficient pressure and correct wiring.
Check and repair circuit connections: Check the contact between the generator's brushes and slip rings to ensure sufficient pressure, secure wiring, and no open circuits, short circuits, or grounding phenomena.
Through the above measures, the problem of zero current in Weifang generator sets can be effectively solved, ensuring the normal operation of the generator.
