An outdoor installation box for an urban electric power engineering transformer substation

Abstract

The invention relates to the technical field of urban electric power engineering facilitates and in particular provides an outdoor installation box for an urban electric power engineering transformersubstation. The outdoor installation box comprises an outer box body fixed to the ground via bolts; an inner box body is fixedly welded to the inner side wall of the outer box body. The outdoor installation box is characterized in that a top supporting frame and the outer box body are connected via L-shaped connecting supporting racks; a detachable metal filter screen is inserted in the top supporting frame so that the surface of the outer box body is prevented from being directly exposed to the rain and the problem is solved that water and dirt accumulate at the surface of an outer box body exposed to the rain and thus heat dissipation is influenced; separating plates provided with metal heat conducting bars at the surface are fixed in the inner box body and the metal heat conducting barsand bottom surfaces of the connecting supporting racks are connected, so that the inner heat can be discharged quickly and the inner heat dissipation performance is greatly improved while the inner air tightness is not influenced.

Description

technical field [0001] The invention relates to the technical field of urban electric engineering facilities, in particular to an outdoor installation box for urban electric engineering substations. Background technique [0002] In the current power transmission process and use process, box-type substations are widely used in order to meet the needs of urban commercial and residential production and living. Since most of them are installed outdoors, the box body of the substation is generally sealed in order to achieve waterproof and dustproof effects, which greatly affects the heat dissipation performance of the box-type substation, and too high temperature not only affects the working efficiency of the transformer in the box and stability, and also has great potential safety hazards, while the internal heat dissipation devices of traditional box-type substations are mostly simple air-cooled heat dissipation devices, and most of the air-cooled heat dissipation devices are d...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved outdoor installation box for urban power engineering substations is provided to solve the problem that the internal heat dissipation structure of the current box-type substation is single and the heat cannot be quickly exported , leading to very limited heat dissipation performance, and long-term rain on the top will cause surface pollution, which will also greatly affect the heat dissipation performance of the top
