Trip is one of the failures encountered in the use of diesel generator set. Many users do not know the reason for the trip of the unit, and it is inevitable to be in a hurry when the trip occurs. Diesel generator set manufacturer, if the unit trip phenomenon, can be checked from the following aspects:
1. Check the external of the transformer set and related equipment in detail to determine whether there is any external fault.
2. Check whether the display device of the generator shows failure, if so, cut off the excitation, if not, should adjust the voltage and frequency of the generator, check whether the power supply is normal or not, whether the starting transformer is connected to each other.
3. If the generator overcurrent protection is caused by busbar differential or substation fault, it is necessary to check whether the external of the generator is normal, and then connect the power grid after isolating the fault.
4. Before tripping, if there is strong excitation effect and current impact, it indicates the internal failure of the generator and transformer, which should be dealt with in time.
5. If there is no strong excitation effect and no current impact before tripping, the power grid is in normal operation, and the engine, generator and main transformer are also in normal operation, then it is necessary to check the action protection, if everything is normal in the voltage boost process, the generator can be connected to the power grid, and then continue to find other reasons.
Lead to diesel generator tripping, there are many reasons why want unit manufacturer to provide the above five kinds of thinking can give you some inspiration, at the time of tripping problems, targeted screening, find out the cause of the problem as soon as possible to solve, if necessary please professional diesel generator set manufacturers to come to maintenance, let into the group back up and running as soon as possible.
