Condensation is easy to occur, which reduces the insulation resistance of the generator.
The temperature rise of the wire increases, causing insulation cracks due to excessive thermal expansion and elongation. The temperature difference between the rotor copper and iron is too large, which may cause permanent deformation of the rotor coil.
The insulation becomes brittle and may not be able to withstand the mechanical torque generated by a sudden short circuit.
Generators (English name: Generators) are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other power machinery to convert water flow, air flow, fuel combustion or atomic nuclei. The energy produced by fission is converted into mechanical energy and passed to the generator, which is then converted into electrical energy.
The water temperature of the diesel generator set is preferably around 80°, and the maximum temperature cannot exceed 95°! Remember not to let the temperature be too high or too low, as it will cause harm to the generator set! (For reference only: YANAN Diesel Generator Answer_: 4000-080-999) The reasons for the water temperature being too high when the diesel generator set is running are as follows: 1. The water tank fan does not rotate. It is easiest to check whether the water tank fan is running normally. The method is to turn on the refrigeration system. If the compressor has started but the fan is still not running, the fan must be faulty; when the water temperature sensor is disconnected, the fan will run by itself to protect the engine. In this case, you can unplug the water temperature sensor. judge. 2. Poor heat dissipation of the radiator. This situation often occurs in summer. During inspection, you only need to open the hood and observe whether the radiator behind the bumper is filled with too many foreign objects. If the radiator is too clogged, you need to go to a repair shop for cleaning. 3. The thermostat cannot be opened normally. In this case, the coolant cannot circulate normally and cannot play a cooling role at all. The main manifestation is that the water tank and return pipe are both at normal temperature (normally they should be hot), and because The gas in the water pipes expands, and both the upper and lower water pipes become very hard. 4. Insufficient coolant This is a situation that is relatively easy to observe. Just open the engine compartment and observe whether the coolant level meets the requirements. 5. The water pump is not working properly. The water pump belt sometimes slips and idling due to long use. When this problem occurs, the main characteristic is that it will return to normal after depressing the accelerator for a period of time. 6. Abnormal water temperature sensor, instrument and circuit. If the above problems have been eliminated, then the excessive water temperature may be caused by the failure of the water temperature sensor or the failure of the instrument or circuit. In this case, it is necessary to go to the maintenance service point for detailed inspection in time.
