Description

Technical Field

[0001] The utility model relates to the technical field of non-encapsulated dry-type transformers, in particular to a non-encapsulated dry-type transformer. Background Art

[0002] A dry-type transformer refers to a transformer whose core and windings are not immersed in insulating oil. It is widely used in places such as local lighting, high-rise buildings, airports, docks, CNC machinery and equipment. Existing non-encapsulated transformers are generally placed indoors for use. The transformer will release a large amount of heat during operation. When operating at rated capacity, it can be allowed to cool naturally by air.

[0003] After searching, the published patent number CN219066569U mentioned a non-encapsulated dry-type transformer, including a base, a transformer body, a top plate and a base. The transformer body is fixedly installed on the top of the base, the top plate is fixedly installed on the top of the transformer body, and the base is fixedly installed on the bottom of the base. A heat dissipation mechanism is provided inside the base; a dustproof mechanism is provided on the top of the base, and the dustproof mechanism includes a first fixed plate. This non-encapsulated dry-type transformer is provided with a dustproof mechanism and a first dustproof net and a second dustproof net to minimize the amount of dust falling on the transformer body, while maintaining the heat dissipation effect of the transformer body, thereby extending the service life of the transformer body and reducing the occurrence of accidents. By pulling the first pull rod and the second pull rod, the operator can quickly remove the first dustproof net and the second dustproof net, which can be convenient for the operator to clean the first dustproof net and the second dustproof net, and can be reused.

[0004] Although the above solution solves the problems raised in the background technology, the following shortcomings still exist: when dissipating heat from the transformer body, the first fan blade and the second fan blade have a single structure and are not easy to move, resulting in a small heat dissipation area and poor heat dissipation effect. At the same time, it is not convenient to disassemble and assemble the first dustproof net and the second dustproof net, resulting in poor protection effect and low practicality.
