In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

As shown in Figures 1-5, a box-type substation includes a rectangular base 8, and vertical plates directly in contact with the ground are fixedly connected around the base 8. Vertically arranged right-angle wrappings 6 are fitted and fixed on the outer end faces of the four right-angle parts of the base 8 . The right-angle wrapping 6 is detachably connected to the base 8, and a flat wrapping is fitted and fixed between the bottoms of every two adjacent right-angle wrappings 6, and the flat wrapping is connected to the base 8 and the base 8. The above-mentioned right-angle wrapping 6 is detachably connected, so as to facilitate the assembly and disassembly of the box-type substation, thereby providing convenience for the maintenance of the box-type substation.

In order to simplify the connection structure of the detachable connection, a plurality of installation holes are provided on the bottom end surface of the right-angle edging 6, the end surfaces of the two ends of the flat edging and the side end surfaces of the base 8. The right-angle edging 6 , The flat edge is fixedly connected with the base 8 by bolts. In this way, the right-angle wrapping 6 , the flat wrapping and the base 8 jointly constitute a supporting structure for installing and fixing the side wall 2 and the top cover 1 of the box-type substation.

In order to improve the assembly convenience between the right-angle wrapping 6 and the base 8, and avoid the sharp corners of the right-angle wrapping 6 from causing injury to the staff, the bottom edge of the right-angle wrapping 6 is designed to be Curved outward. Similarly, the sharp edges and corners of the edging of the flat panel are also cut off, so as to improve the safety of workers during the assembly process.

Wherein, the two right-angled surfaces of the right-angled edge 6 are integrally formed, that is, the two planes are formed by a stamping process and bent at 90°, so as to be assembled and fixed with the base 8, so the right-angled surface of this structure Compared with traditional vertically supported splicing panels, the hemming 6 has higher mechanical strength, so the product quality of the present invention can be further significantly improved. The side wall 2 includes a door panel 3 connected to the right-angled edge 6 through a hinge.

In order to improve the anti-corrosion capability of the door panel 3, a layer of dense protective coating is attached to the outer surface of the metal plate through a plastic spraying process. The dense protective coating is acrylic powder coating or polyester powder coating. In addition, because the door panel 3 is provided with an insulating interlayer in the middle of the structure, the door panel 3 has good thermal insulation performance, its structure is stronger and more durable, and its appearance is more beautiful. The structure of the door panel 3 is shown in FIG. 6 .

A starlight camera is installed on the door lock mounting hole in the door panel 3, and the starlight camera is located at the underside of the cover plate of the door lock mounting hole. The main controller of the starlight camera passes the video signal through the wireless network. The video is transmitted to the monitoring host in the main control room of the substation, and the video taken by the starlight camera is displayed through the LED display of the monitoring host. The installation of the starlight camera provides a stronger guarantee for the safe use of the door panel 3 . This is mainly because the starlight camera can clearly display the illegal operation process of picking the door lock, stealing or maliciously destroying the door lock on the LED display of the monitoring host under low light conditions, such as at night, so that the staff in the main control room Real-time grasp of the safe use of each substation. In addition, the starlight camera will only be exposed when the cover is opened to open the door lock, so the cover has a good protective effect on the starlight camera.

The main controller of the starlight camera is equipped with an infrared sensor switch. Whether someone approaches the door lock is judged by the infrared sensor switch, and once someone opens the cover plate, the starlight camera in a sleep state will be quickly turned on to make it in a normal working state. This design enables the starlight camera to have the advantage of saving electric energy. In addition, the cover plate is connected to the door plate 3 through a hinge rotation or through a sliding slot. The door lock in the door panel 3 is a heaven and earth linkage lock.

Heat dissipation holes 4, the top of the top cover 1 is provided with a large second heat dissipation hole 5 or a plurality of small second heat dissipation holes 5 evenly distributed in a linear array, which can significantly increase the heat dissipation paths of the box-type substation to achieve The purpose of optimizing the heat dissipation effect of the box-type substation.

The top end of the top cover 1 is fixedly connected with a cover body, and the top end of the top cover 1 is fixedly connected with a cover body. As for the sand support, the outer edge of the cover top is fixed to the rain-shielding eaves through a blind rivet, the rain-shielding eaves are arranged obliquely, and the inclination trend of the rain-shielding eaves is consistent with that of the main body of the top cover.

The curved ventilation and sand-proof support is fixedly connected with the vertical plate in the top cover 1, and the curved ventilation and sand-proof support includes an upper support plate and a lower support plate, and the upper support plate and the lower support plate are core-pulled. The rivets are fixedly connected as one, and the upper support plate and the lower support plate are provided with the second cooling holes 5 for ventilation, the upper support plate and the lower support plate are located inside the rain-shielding eaves, and the top cover 1 The second cooling holes 5 are located on the inner side of the vertical plate. The ventilation and anti-sand bracket of the curve and the top cover 1 jointly constitute the slope curve.

This design allows rainwater to flow to the outer surface of the top cover 1 under the blocking of the vertical plate even after passing through the gap for air circulation between the rain-shielding eaves and the roof. Since the top cover 1 is arranged obliquely downward, and there is a certain gap between the bottom of the rain eaves and the top cover 1, the rainwater entering the inner side of the eaves will also flow from the top of the bottom of the eaves. Quickly slide off cover 1.

A plurality of exhaust fans 7 are installed at the lower end of the top cover 1 . The exhaust fan 7 includes a mounting seat in a rectangular mounting frame structure. In order to make the installation operation between the exhaust fan 7 and the box-type substation more convenient, an assembly hole for assembling and connecting with the top of the box-type substation is opened on the edge of the mounting base. A shock-absorbing rubber gasket is arranged between the mounting seat and the top cover 1 , this design can make the running state of the exhaust fan 7 more stable, and significantly reduce the impact of the mounting seat on the top cover 1 .

The rear end of the installation frame is fixedly connected by bolts with a plurality of support ribs bent backwards to form an arc, and the arc design is to improve the supporting capacity of the support ribs. The supporting ribs are evenly distributed in a circular array with the centerline of the mounting seat as the axis and constitute a bracket for assembling parts.
