[0002] At present, the forced oil circulation air-cooled transformer coolers in our factory are distributed on the left and right sides of the transformer, with 4 groups on one side and 3 groups on the other side. 3-4 groups of independent coolers are installed on each side, and each group has three cooling fans installed vertically. However, after long-term use, the surface of the cooler is prone to dirt, especially in spring, when a large amount of poplar fluff is attached to the transformer cooler, which may even increase the load of the cooling fan, thereby causing the circuit line to heat up and overload tripping. In order to solve the above problems, our factory originally used manual flushing to do the operation, which required 4 people to spend 3-4 hours to complete, and the cleaning efficiency was not high. Moreover, as an important equipment in the power production process, the transformer cannot be shut down at any time, and can only be flushed by manpower in operation.
