Embodiment
In order to more clearly understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with drawings and Examples, the utility model is described further.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the utility model, but, the utility model can also adopt and be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of the specific embodiment of prospectus below.
Embodiment, as shown in Figure 1 and Figure 2, a kind of electric power box-type substation comprises casing 1, and casing 1 comprises base plate 4, shell 2 and top cover 3.
In order to keep the firm and head cover drainage of body structure, shell 2 adopts stainless steel material, and top cover 3 is arranged to inclination ramp shaped, and form triangular structure and be arranged at shell 2 and push up, top cover 3 adopts waterproof, radiation proof material.Consider transformer station's each function element ventilation and heat demand, shell 2 is provided with blow vent 15, base plate 4 is provided with hole structure 17, forms a space that can maintain the circulation of air.
Box house is divided into three regions by dividing plate: hyperbaric chamber 5, low-pressure chamber 6 and transformation room 7.Narrow and small in order to overcome electric power box-type substation inner space, be inconvenient to dismantle and the problem such as maintenance, hyperbaric chamber 5 is arranged at side, transformation room, and low-pressure chamber 6 is arranged at dead ahead, transformation room, form delta structure, transformer 16 can pull out or hang out from top easily in casing 1.Hyperbaric chamber, low-pressure chamber are arranged at both sides, transformation room and form order character form structure, and order character form structure is conducive to user's maintenance, changes and increase-volume.
