Learn the generator and auxiliary engine inspection items:
1. The coil temperature and iron core temperature of the generator cannot exceed the standard.
2. The air temperature at the inlet and outlet of the generator cannot exceed the standard.
3. The carbon brush slip ring has no sparking.
4. There is no discharge or spark inside the generator.
5. The excitation current and voltage of the generator must match the primary voltage and current of the generator and cannot exceed the standard.
What are the generator inspection items?
Yes. Generator wind temperature refers to the cooling air temperature of the generator coil. When the generator is working, a certain air temperature must be maintained to ensure the cooling effect of the generator coil. If the temperature of thent is too low, the generator coil will not be cooled sufficiently, causing the generator to overheat and affect its normal operation.
What should be the rated generator inlet air temperature and outlet air temperature?
The generator set inspection items are as follows :
1) The temperature of the coil and iron core of the generator The temperature cannot exceed the standard
2) The air temperature at the inlet and at the generator output cannot exceed the standard
3) There is There is no spark in the carbon brush slip ring
4) There is no There is no discharge inside the generator, no sparking
5) The excitation current and voltage of the generator must match the primary voltage and current of the generator and cannot exceed Standard.
What are the dangers if the air temperature of the turbogenerator is too high or toop low?
The inlet air temperature is ambient temperature; the outlet air temperature should not exceed 40°C.
According to international technical requirements, the ambient operating temperature of the generator is set at 40°C. All designs and wattages are based on this ambient temperature. For generators, ambient temperature is the inlet air temperature of the generator. Since the generator works with the diesel engine, the heat generated by the diesel engine will cause the entire space to exceed 40°C.
The ambient temperature of the generator during actual operation must not exceed 40°C. If the actual ambient temperature exceeds 40°C, the generator must operate at reduced power. For the ambient temperature, if it is lower than 40°C, the generator power may be higher than the rated power.
Detailed information:
1. Check that the internal combustion engine and the transmission part of the generator should be reliably connected, the output line wires should be well insulated, and all instruments should be complete and efficient.
2. After starting, it should run at low speed for 3-5 minutes. The operation can only be started after the oil temperature and pressure are normal. There should be no abnormal noise when the generator increases in speed, the slip ring and commutator brushes should be in good contact, and there should be no jumps or sparks.
3. Before shutdown, you must first turn off the main switches of each power branch, gradually reduce the load, turn off the main power switch of the generator and return the excitation rheostat to the positionn of maximum resistance to reduce the voltage to the lowest value. Turn off the excitation switch and neutral point ground switch to stop the internal combustion engine.

If the wind temperature of the generator is too high, the temperature of the stator coil and core of the iron will increase accordingly, making the insulation brittle, oxidation, loss of mechanical strength, significantly shortening the life of the generator and, in severe cases, it can cause damage to the generator insulation, breakdowns and accidents .
If the wind temperature is too low, the hydrogen gas will condense and leak, causing water droplets to condense on the generator coil, reducing its insulation capacity and damaging the generator. Therefore, the wind temperature of the generator must be kept within the range specified by theregulation during normal operation.
