Problems solved by technology

At present, in some special applications, special cooling methods, such as forced air circulation and water cooling, are adopted to solve these problems. Usually, the cost is high and cooling devices such as fans and water pumps are prone to failure, which may easily cause the transformer to overheat and even burn out.

Abstract

The invention relates to a fully-sealed dry-type transformer. The transformer comprises a transformer shell with a right sealing structure, a transformer body is installed in the transformer shell, and key components are completely isolated from the external environment. The transformer shell is composed of a heat dissipation wall with a heat dissipation structure, and heat generated by an internal electrical structure can be effectively dissipated. The fully-sealed dry-type transformer provided by the invention can be applied to all application scenes of conventional liquid immersion type and dry-type transformers, has lower shutdown failure rate and longer service life, and is completely maintenance-free.

Description

technical field [0001] The invention belongs to the technical field of transformer devices, in particular to a fully sealed dry-type transformer. Background technique [0002] Generally, transformers can be divided into oil-immersed transformers and dry-type transformers according to the insulation medium. Transformers that undertake long-distance and large-capacity transmission generally use oil-immersed transformers due to their high voltage and large capacity. Among them, due to the relatively small voltage and capacity, both oil-immersed transformers and dry-type transformers are used. [0003] In some general power supply occasions, such as villages, communities, etc., where the requirements for transformer installation space and fire protection are not too high, oil-immersed transformers are often used; while in some buildings, such as basements, buildings, or ships, etc., the installation space and fire protection requirements are not very high. Where there are stric...
