Green energy-saving transformer substation ventilation device

The invention relates to the technical field of transformer substation ventilation, in particular to a green and energy-saving transformer substation ventilation device which comprises a base frame, transverse surrounding plates and longitudinal surrounding plates, and the transverse surrounding plates and the longitudinal surrounding plates are vertically arranged on the four sides of the base frame in a surrounding mode. The two sets of transverse surrounding plates are oppositely arranged on the two sides of the base frame in the short edge direction in a surrounding mode. The transverse surrounding plate is composed of a front movable cabinet door and a rear surrounding plate and used for surrounding the two sides of the base frame in the long edge direction. The top sealing module is horizontally and fixedly arranged at the top of the base frame and used for sealing the top of the base frame. The natural air supply module is fixedly arranged on the outer wall of the transverse coaming in a vertical state
