The 800kw diesel generator set voltage regulating board is an important part of the set. It can adjust the excitation current according to the change of the generator load to maintain the terminal voltage as a given value; control the reactive power distribution among the generators in parallel operation; Stabilize the voltage, and demagnetize the generator when there is a fault inside the generator to reduce the degree of fault loss; implement the maximum excitation limit and the minimum excitation limit for the generator according to the operating requirements. Explain the troubleshooting method of the pressure regulating plate of the 800kw diesel generator set.
1. First check the oil level of the engine. When the generator voltage regulating board is normal, the installation wiring of the oil leakage alarm can be removed. If the starter can start, the oil alarm installation is damaged.
2. The starter can be started without burning the switch, which indicates that the switch is short-circuited. The burner switch can be removed for inspection or replacement.
3. If the spark plug magnet is damaged or the intermediate electrode is corroded and damaged, the spark plug should be replaced.
4. The spark plug is too dirty, you can clean it with gasoline, then adjust the electrode gap to 0.6mm-0.8mm, then dry it and use it again.
5. Whether the resistance values of the low-voltage coil and charging coil of the accessories are within their limits, or whether the peak voltage can be checked normally, or the relevant coil or the entire electronic burner has been replaced.
6. If the connection between the high voltage wire and the spark plug is not firmly connected, it can be replaced with a new governor plate. When the high-voltage line is exposed to moisture and leaks, it can be removed for cleaning and cleaning of the high-voltage line.
7. Assuming that the combustion system is normal, it should be reconsidered whether the oil circuit can be dredged, and whether the diesel in the fuel tank can be mixed with water.
8. Check whether there is diesel oil in the fuel tank, then carefully check whether the fuel switch can be turned on, and then dredge the fuel tank through the air hole, so that the fuel tank is connected to the atmosphere to form a pressure difference.
The above method is the fault maintenance method of the pressure regulating plate. The pressure regulating plate of the 800kw diesel generator set has the functions of regulating, stabilizing the voltage and overvoltage protection. When a fault occurs, the user must repair it in time.
