Outdoor transformer box

Abstract

The invention relates to an outdoor transformer box. The outdoor transformer box comprises a box body which comprises a back plate, two side plates, a top plate, a bottom plate and a front door, wherein the top plate is arranged forward, the front end of the top plate extends to the front and upper part of the front door and rain discharge grooves which extend towards the direction of the front door from the back plate are arranged in the top plate; cooling devices are symmetrically arranged on the two side plates; each cooling device comprises a cooling hole and a rain baffle hinged with the upper part of the cooling hole; and each rain baffle is provided with a rain adjusting device. The outdoor transformer box has the advantages that the rain conveniently slips off from the upper part of the front door by a forward top plate design method; the top plate extends out of the front part of the front door; when the rain comes, the front door with a poor sealing effect is protected to the maximum extent; and the rain baffles are arranged on the cooling holes and the opening and closing conditions of the rain baffles can be automatically adjusted by the rain adjusting devices according to the rain condition, so that effective heat dissipation can be carried out when the rain is prevented.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an outdoor transformer box. Background technique [0002] In the power system, all kinds of high and low voltage transformers are very important and often used power equipment, and most of the transformers are usually installed outdoors to facilitate ventilation and maintenance. However, this kind of transformer placed outdoors also has a big disadvantage. It is easy to be exposed to rain and snow. Due to the long-term rainwater immersion, it is easy to cause a short circuit in the internal circuit and damp inside the oil tank, which seriously affects the service life of the transformer. Due to the heat dissipation requirements of the transformer, there are usually cooling holes on the box body, which can play a certain role in cooling. However, in rainy days, the cooling holes are easy to enter water, which affects the rainproof performance of the transformer box. Cont...
