Should the generator rotor insulation standard be converted to 75 degrees? Why does the short circuit resistance need to be converted to 75 degrees? ? Excitation resistance is not used_Baidu knows
When the generator is used under rated working conditions, the voltage, current and loss of the excitation system are based on the value of the excitation resistor. Rotor DC resistance at 75 or 130 degrees. The 75 and 130 here are based on generator isolation. The quality is determined, choose 75 degrees for B-grade insulation and choose 130 degrees for F-grade insulation. So the generator...

1 When it is found that water has entered the generator, immediately stop the generator if it is running . He is not allowed to light it. he is stopped.
2. Support one side of the mobile generator set with a hard object and lift it so that the oil drain part of the engine oil pan is in the lowest position, unscrew the oil drain plug, remove it. oil dipstick and make the oil pan. The water inside drains out on its own. When the oil is about to drain, let the oil and water drain for a while, then tighten the oil drain plug.
3. Remove the air filter, replace the new filter element and soak it in oil.
4. Remove the intake pipes andexhaust and muffler, and remove any water from the pipes. Turn on the pressure relief, crank the diesel engine to generate electricity, and observe if water flows from the inlet and exhaust ports. If there is water drained, continue to rotate the crankshaft until all the water in the cylinder is drained. Install the intake and exhaust pipes and mufflers, add a little engine oil to the air inlet, crank the crankshaft a few times, then install the air filter.
5. Remove the fuel tank, drain all oil and water from it, check for water in the fuel system and drain it.
6. Release the waste water into the water tank and water channels, clean the water channels and add clean river water or boiled well water until the water float mounted. Turn on the throttle switch and start the diesel engine. After it startedage of the diesel engine, pay attention to the rising engine oil indicator and listen for any abnormal noise coming from the diesel engine. After checking whether all parts are normal, run the diesel engine. The operating sequence is first at idle, then medium speed, then high speed. The running time is 5 minutes each. After break-in, stop the engine and drain the engine oil. Add new engine oil again, start the diesel engine and run it at medium speed for 5 minutes, then it can be used normally.
7. Disassemble the generator, check the stator and rotor inside the generator, then dry them before assembly.
Users of mobile generator sets should pay attention to protecting the unit after the unit is wet and in humid environments, to ensure the normal operation of the generator set.
