How to solve some 'difficult and complicated problems' of generator sets?

During the use of generator sets , customers will have many 'whys'. Haixing has prepared some difficult problems about the unit and will explain them in detail below. More difficult problems will be published on Haixing's official website one after another. Your attention is welcome.

1. What are the conditions for the use of two generator sets in parallel? What device is used to complete the parallel work?

Answer: The conditions for parallel machine use are that the voltage, frequency and phase of the two machines are the same instantaneously. Commonly known as 'three simultaneous' means that the parallel machine is used to complete the parallel machine work. It is generally recommended to use fully automatic merging cabinets, and try not to manually merging the machine, because the success or failure of manual merging depends on human experience, and the reliable success rate of manual merging of diesel generators is equal to 0.

2. What is the power factor of a three-phase generator? Can a power compensator be added to improve power factors?

Answer: The power factor is 0.8. No, because charging and discharging of the capacitor will cause small power supply fluctuations. and unit oscillation.

3. Why do customers need to tighten all electrical contacts after every 200 hours of unit operation?
Answer: The diesel generator set is a vibrating worker. Once the electrical fasteners are loose, a large contact resistance will be generated, causing the unit to run abnormally.

4. Why is the generator room guaranteed to be clean and the ground is free of sand?

Answer: If the diesel engine sucks dirty air, it will reduce the power; if the generator sucks sand and other impurities, it will damage the insulation between the stator gap, which will cause burning.
