Abstract

The utility model relates to the technical field of transformers, in particular to an anti-corrosion dry-type transformer. The anti-corrosion dry-type transformer comprises a core and coil windings, and is characterized in that insulating layers with certain thickness are arranged on the surfaces of the core and the coil windings integrally and hermetically, and a heat dissipation opening is formed between the insulating layers of every two adjacent coil windings when the insulating layers are cast integrally. The anti-corrosion dry-type transformer has the advantages that the insulating layers are cast outside the core and coil winding structure of the transformer integrally, so that integral corrosion resistance of the anti-corrosion dry-type transformer is improved; by the aid of the heat dissipation openings between the coil windings, heat dissipation area of the transformer is enlarged, and heat dissipation effect and working reliability of the transformer are enhanced.

Description

Anticorrosive dry-type transformer

Technical field

The utility model belongs to transformer technology field, is specifically related to anticorrosive dry-type transformer.

Background technology

Often need to apply special transformer and meet the requirement of its applied environment in some special industries, as the transformer of application and extra large underwater work electrical equipment, be operated in the transformer etc. of high humidity place, deep-etching liquid or gaseous environment.And existing transformer technology mostly only adapts to the less demanding occasion of insulation environment, although there are some so-called full-sealed transformers, the relative conventional environment of its sealing property is higher with transformer, but can not meet the requirement of safe changing voltage in seawater, deep-etching gaseous environment.

Summary of the invention

The purpose of this utility model is to overcome existing transformer technology can not adapt to the deficiency in highly corrosive environments work, and a kind of anticorrosive dry-type transformer having compared with high leakproofness is provided.

For achieving the above object, the technical solution of the utility model comprises iron-core workpiece and coil windings.It is characterized in that: on the surface of iron-core workpiece and coil windings, not only integral sealing is provided with certain thickness insulating barrier, and in the time of integrated poured insulating barrier, between the insulating barrier of each 2 adjacent coil windings, be all provided with thermovent.

The beneficial effects of the utility model are: at transformer fe core body and the casting insulated layer of coil winding arrangement external overall, improved the corrosion resistance of transformer entirety; Thermovent between coil windings has strengthened transformer area of dissipation, has strengthened the radiating effect of transformer and the reliability of work.
