The fan room 10 may be provided in a room structure existing in the prior art. The blower room 10 is usually provided with air intakes 101 at its peripheral side. Preferably, a filter screen is disposed on the air inlet 101 to prevent foreign matters from entering the blower room 10. Outside normal temperature air enters the fan room 10 through the air inlet 101. Alternatively, the blower room 10 may be disposed underground, and the air intake 101 thereof is disposed at the top of the blower room 10. In this embodiment, the blower room 10 is disposed on the ground, preferably above the fire pool 2. The normal temperature air entering the blower room 10 is sucked into the blower group 11.

Specifically, the first fan 115 is used for preparing the humidity-standard air, the humidity-standard air is then led into the fire-fighting water tank 2 for cooling, and the second fan 116 pushes the low-temperature humidity-standard air into the transformer substation 3. Alternatively, when the air humidity in the substation 3 meets the requirement, the first fan 115 may not perform the preparation of the humidity-marked air, but directly introduce the normal-temperature air into the fire-fighting water tank 2 for cooling.
