In a further technical scheme, two or more air inlet compartments are arranged.

The ventilation method of the ventilation dustproof transformer substation is characterized in that outside wind is driven by an air inlet fan to enter an air inlet compartment from an air inlet and then enter a foundation, after the outside wind is subjected to speed reduction and sedimentation, the outside wind enters a low-pressure chamber and then is exhausted from a ventilation grid on the side surface of a top cover through air duct flexible connection, and preferably, two or more air inlet compartments are arranged.

Through the technical scheme, the utility model provides a dustproof transformer substation of ventilation has following advantage:

1. the air inlet and the air inlet fan form an independent air inlet compartment, and dust and rainwater cannot enter the interior of the transformer substation through the compartment;

2. the wind enters the transformer substation foundation, the size of the foundation is large, and the effects of weakening wind speed and reducing dust can be achieved;

3. independent air inlet compartments are arranged by utilizing redundant space in the transformer substation, and an air inlet duct is integrated into the transformer substation, so that a ventilation shaft does not need to be independently established, and materials and civil engineering cost can be saved;

4. inside the top cap was arranged in to the transformer substation's top fan of airing exhaust, aired exhaust through the ventilation grille of top cap side, can solve the problem of leaking.

5. The air inlet compartment is connected with the high-voltage chamber, the transformer chamber and the low-voltage chamber in a sealing way, and the protection grade reaches above IP 54.
