Abstract

The utility model discloses a transformer box which comprises a transformer box body and a box cover. A box eave is arranged at the top part of the transformer box body; the edge of the box cover is provided with downward folding edges; and a notch is arranged between two adjacent folding edges. As the edge of the box cover is provided with the downward folding edges, and rain water on the transformer box cover can flow downwards along the folding edges without entering into a sealing part in a rainy day so as to avoid affecting sealing performance due to penetration of the rain water. The notch is arranged between the two adjacent folding edges so that the box cover is easy to manufacture, and the manufacturing cost is low. In addition, due to the blocking of the folding edges, the problem of aging a sealing rubber strip caused by ultraviolet irradiation to affect the sealing performance is solved; thereby ensuring the safe operation of a power transformer.

Description

A kind of transformer tank with flanging structure case lid
Technical field
The utility model belongs to the power transmission and transforming equipment technical field, is specifically related to a kind of transformer tank with flanging structure case lid.
Background technology
At present, most of power transformer case case is along use flat plate usually, and case lid also adopts plate armature.Because case lid is plate armature, case cover and case along between have the gap, rainwater easily along case lid from case lid with the case edge between the gap enter into seals at, cause easily and seep water and influence performance of products; In addition, the sealing joint strip that exposes is subject to ultraviolet irradiation and wears out, and influences its sealing property.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of transformer tank is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The transformer tank of the utility model comprises transformer-cabinet and case lid, and the transformer-cabinet top is provided with the case edge, and the edge of case lid is provided with downward flanging, is provided with breach between adjacent two flangings.
Angle between flanging and the case lid less than 90 the degree, between flanging and the case lid end face by arc transition.
Because the utility model is provided with downward flanging at the edge of case lid, when raining, the rainwater that transformer tank covers can be dirty along flanging, can not get into seals at, and having avoided influences sealing property because of rainwater infiltrates.Be provided with breach between adjacent two flangings, being easy to case lid like this must process, and it is low to make the ability cost.In addition, because flanging blocks, solved the problem of sealing joint strip because of ultraviolet irradiation burn-in effects sealing property.Thereby guaranteed the safe operation of power transformer.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is an A part partial enlarged drawing among Fig. 1.
Embodiment
The transformer tank of the utility model comprises transformer-cabinet 2 and case lid 1, and transformer-cabinet 2 tops are provided with case along 2-1, and the edge of case lid 1 is provided with downward flanging 1-1, is provided with breach between adjacent two flangings.
Angle between flanging 1-1 and the case lid 1 less than 90 the degree, between flanging 1-1 and case lid 1 end face by arc transition.
In the utility model when assembling,, the case that case lid 1 is covered the power transformer casing of having placed sealing joint strip 3 is along on the 2-1, connects fixingly then through fastening bolt 4, and the turnup structure on the case lid plays the covering effect to sealing joint strip.

Claims (2)
