How to solve some 'difficulties' of the generator set?

Generator setCustomers will have a lot of 'why' during the use of the unit. Haixing has prepared some difficult questions about the unit. They will be explained in detail below. More difficult questions will be released on the Haixing official website one after another. You are welcome to focus on.

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

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

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

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

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

4. Why must the generator room be kept clean and the floor free of floating sand?

Answer: If the diesel engine inhales dirty air, the power will decrease; if the generator inhales sand and other impurities, the insulation between the stator and rotor gaps will be damaged, and in severe cases, it will cause burnout.
