The wall waterproof structure is a waterproof opening arranged along the inner side of the upper end surface of the wall of the pit and integrally formed with the wall of the pit. The wall waterproof structure of the utility model can resist rainwater from invading the pit from the outer side of the upper end surface of the pit, and provides favorable conditions for safe and reliable operation of the buried transformer.

Description

A wall waterproof structure of buried transformer

technical field

The utility model relates to a wall waterproof structure of an underground transformer.

Background technique

The buried transformer is installed in the basement or cellar, which can advocate green power and optimize the urban environment. It is suitable for streets, highways, bridges, tunnels, parking lots, and is suitable for lighting and power systems in urban environments, airports, ports, tourist attractions, etc., especially Suitable for densely populated central cities. The buried transformer is divided into two parts above ground and underground, and its body is installed in a pit constructed of concrete without occupying surface space. The cover of the buried transformer is equipped with high-voltage casing and low-voltage terminals, high-voltage load switch and backup fuse, plug-in lightning arrester, pressure relief valve, vacuum pressure gauge, temperature control and oil level indicator. These accessories can be found in Observe and operate on the ground. The oil tank is made of stainless steel, with a fully sealed structure and a closed welded structure along the tank to minimize the sealing area, and can operate safely for a long time in the special environment in the ground.

However, the buried transformer has not completely solved the safety problem at the upper end of the pit, so it has been greatly affected in the transformation of the urban power grid into the ground. Rainwater can flow into the pit through the outside of the upper end surface of the pit in rainy days, causing the inside of the pit to accumulate water, which brings trouble to the insulation of the transformer.

Contents of the invention

The purpose of this utility model is to overcome the defects of the prior art and provide a wall waterproof structure for buried transformers, which can resist rainwater from intruding into the pit from the outside of the upper end surface of the pit, and provide safe and reliable protection for buried transformers. Operation provides favorable conditions.

The technical solution to achieve the above purpose is: a wall waterproof structure of an underground transformer, the buried transformer includes a rectangular cubic pit whose upper part is exposed to the ground and has an upper end opening, a transformer installed in the pit, and a transformer located in the underground pit. The aboveground part at the upper end of the pit, the aboveground part includes a ventilation window and a cover plate, and the ventilation window includes a window installed on the outer side of the upper end surface of the wall of the pit; the waterproof structure of the wall is along the A waterproof port is provided on the inner side of the upper end surface of the wall of the pit and integrally formed with the wall of the pit.

In the wall waterproof structure of the above-mentioned buried transformer, the height and width of the waterproof opening are both 50mm.

The waterproof structure of the wall of the buried transformer of the utility model can resist rainwater intruding into the pit from the outside of the upper end surface of the pit, so as to prevent water accumulation inside the pit and provide favorable conditions for the safe and reliable operation of the buried transformer. condition.

Description of drawings

Figure 1 is a schematic diagram of the structure of the buried transformer;

Fig. 2 is a structural schematic diagram of the wall waterproof structure of the buried transformer of the present invention.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to FIG. 1 , the buried transformer includes a rectangular cuboid pit 10 with an upper part exposed to the ground 20 and an upper end open, a transformer installed in the pit 10 and an aboveground part located at the upper end of the pit 10 . The above-ground part comprises a ventilation window and a cover plate 3 . The ventilation window includes a window 2 installed on the outer side of the upper end surface of the wall of the pit 10 .

Referring to Fig. 2 again, the wall waterproof structure of the buried transformer of the present utility model is a waterproof port 40 which is arranged along the inner side of the wall upper surface of the pit 10 and integrally formed with the wall of the pit 10. The height and width of the waterproof port 40 are both 50 mm.

The wall waterproof structure of the buried transformer of the utility model can be reserved during the wall construction of the pit. It can resist rainwater intruding into the pit from the outside of the upper end surface of the pit, prevent the interior of the pit from accumulating water, and provide favorable conditions for the safe and reliable operation of the buried transformer.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
