Also, the height of the first arched deck portion is greater than the height of the second arched deck portion.

The utility model has the advantages and positive effect:

1. The utility model discloses the top cap adopts an organic whole to pour the shaping structure, and the lamina tecti part that is located upper portion adopts to set up arched dysmorphism apron structure, has increased the height and the inner chamber volume of top cap, is favorable to reducing the influence of sunshine insolate to the temperature rise.

2. Shutter is installed at first arch apron part both ends at the top cap, and sets up the air outlet around the eave, has increased the area of transformer room air outlet like this by a wide margin. In addition, compared with the existing air outlet arranged below the top eaves and above the door lintel, the height of the air outlet is improved, and the height difference between the air inlet and the air outlet of the transformer substation is increased, so that ventilation and heat dissipation are facilitated.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A prefabricated substation top cover please refer to fig. 1-6, its invention point is:

the top cover is an integrated pouring forming structure with a steel bar prefabricated inside, and the pouring material is a glass fiber reinforced cement material. The top cover is composed of a top eave 2 in contact fit with the top of the wall body and a top cover plate 1 connected with the upper end of the top eave. The top cover plate is of a special-shaped cover plate structure and comprises a flat cover plate part 1-1, a first arched cover plate part 1-2 and a second arched cover plate part 1-3 vertically connected with two sides of the first arched cover plate part, wherein the first arched cover plate part is arranged along the front-back direction, and the second arched cover plate part is arranged along the left-right direction. Shutter mounting openings are formed in the front end and the rear end of the first arched cover plate part, and shutters 3 for achieving air outlet are fixedly mounted at the shutter mounting openings at the two ends. Air outlets 2-1, such as rectangular air outlets shown in the attached drawings, are arranged on the periphery of the outer side of the contact part of the top eaves and the top of the wall body.
