[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The automatic control device of the power prefabricated cabin substation starts the vacuum fan to extract and discharge the hot air inside the main body, and then transports the outside air to the water tank through the air pump, so that the clean water in the water tank washes the air, and then removes the dust in the air.
