Under normal circumstances, the generator is not always running at full load, and the average running hours (daily average, monthly average, annual average, etc.). ) converted to the number of running hours at full load.
Control of running time of generator set;
Before the load operation, the generator set should make the following preparations:
1: After the diesel generator is successfully started, the no-load voltage is 400V and the frequency is 50HZ, and there is no big deviation in the three-phase voltage balance. If the voltage deviates too much from 400 volts and the frequency is lower than 47HZ or higher than 52HZ, the diesel generator should be inspected and repaired before the load operation can be carried out;
2. The coolant in the radiator should be saturated. When the temperature is above 60 degrees Celsius, the coolant can be connected with load, and the operating load should be gradually increased from small load to normal operation;
3: The oil level is within the specified scale line, and the oil pressure should not be lower than 0.2MPA after starting.
4: The warning sign of engine air filter pollution should be green. If the display is red, replace the air filter with a new one before running the load;
5: The grounding of the whole generator set is firm and effective, the cable connection is correct and firm, and there is no skin breakage;
6. The generator air switch can be opened and closed freely and flexibly, and the capacity of the air switch should be close to the generator current and effectively protected;
7. Finally, the simplest and most important link is that there is enough diesel in the fuel tank of diesel generator set for Cummins generator to run under load.
