Abstract

The invention belongs to the field of cooling devices, and particularly relates to a main transformer cooling device. Air cooling is mostly adopted for the cooling structure of an existing dry-type transformer, there is only a single cooling mode, the cooling effect is poor, the transformer is easily damaged due to over-high temperature in hot summer, and thus, the requirements of people cannot bemet. In order to solve the problem, the scheme as follows is put forward: the main transformer cooling device comprises a shell of a hollow structure, a mounting base is fixedly mounted on the bottominner wall of the shell, a placing groove is formed in the top of the mounting base, a transformer body is placed in the placing groove, two ventilation openings are formed in the top of the shell, and a same dustproof filter plate is fixedly mounted on the inner walls of the two sides of each ventilation opening. The main transformer cooling device is simple in structure and convenient to operate. Dust adhered to the dustproof filter plates can be cleaned and collected while the transformer body can be rapidly cooled, the situation that the transformer body is damaged due to too high temperature is prevented, and therefore, the requirements of people are met.

Description

technical field [0001] The invention relates to the technical field of cooling devices, in particular to a cooling device for a main transformer. Background technique [0002] According to relevant data records, dry-type transformers have developed rapidly in the past 20 years, especially in distribution transformers, dry-type transformers account for an increasing proportion. 30%-40%, the safe operation and service life of dry-type transformers depend largely on the safety and reliability of transformer winding insulation. In addition to the increase of its own temperature, it will also increase the temperature of the surrounding medium. When the temperature of the winding exceeds the heat resistance limit of the insulating material, the insulating material will be damaged. This is one of the main reasons why the transformer cannot work normally, and it will reduce The service life of the transformer, therefore, the cooling of the dry-type transformer becomes the focus of ...
