Embodiment Construction

[0037] The following is attached Figure 1-5 The application is described in further detail.

[0038] The embodiment of the present application discloses a modular outer box. refer to figure 1 , The modular outer box includes a box body 1, and two box doors 2 are installed on the front and back of the box body 1. Both the box body 1 and the box door 2 are provided with reinforcement structures 3 .

[0039] refer to figure 1 , each side plate of the box body 1 is provided with cooling holes 11 . The heat dissipation holes 11 on the top and bottom surfaces of the box body 1 are evenly arranged in several rows, and the heat dissipation holes 11 on the four vertical sides of the box body 1 are divided into two groups, along the upper side of the vertical side of the box body 1 A set of cooling holes 11 are respectively provided on the side and the lower side. The upper group of cooling holes 11 includes five rows of cooling holes 11 , and the lower group of cooling holes 11 ...

Abstract

The invention relates to a dry-type transformer and a modular outer box thereof, and relates to the field of power transformers. The dry-type transformer comprises a box body, a plurality of rows of heat dissipation holes are formed in the box body, a reinforcing structure is fixedly arranged on the box body, and the reinforcing structure comprises a plurality of rows of box bulges fixedly arranged on the box body; and the same row of heat dissipation holes are formed along the same datum line, the row of box body bulges are arranged along a straight line parallel to the datum line, the box body bulges are adjacent to the heat dissipation holes in position, and the length of the box body bulges in the datum line direction is larger than that of the heat dissipation holes in the datum line direction. The strength of the side plates of the box body is improved, meanwhile, a reinforcing structure is not additionally installed, and the cost increase amount is small.

Description

technical field [0001] The present application relates to the field of power transformers, in particular to a dry-type transformer and its modular outer box. Background technique [0002] With the continuous improvement of urban power grid power supply requirements and the advancement of transformer technology, dry-type transformers are becoming more and more common in our country. Dry-type transformer refers to a transformer whose iron core and winding are not immersed in insulating oil. It is widely used in local lighting, high-rise buildings, airports, docks and other places. [0003] Since the dry-type transformer is used in various places with different environments, especially in the open air, it is necessary to install a protective box. However, after installing the protective box, it will more or less affect the heat dissipation effect of the dry-type transformer. If some types of transformers have poor heat dissipation, they are prone to danger. Therefore, many h...
