Dry-type transformer

Abstract

Disclosed is a dry-type transformer comprising a transformer body, a drip-proof cover, a gear adjusting device and a mutual inductor fixing device, wherein the drip-proof cover, the gear adjusting device and the mutual inductor fixing device are arranged on the transformer body. The drip-proof cover is in an umbrella cover shape and is installed on the transformer body through a screw rod. The drip-proof cover is designed on the transformer body, so that condensation on a ceiling is prevented from dripping on the transformer body, and the risks of breakdown and burnout of the transformer are avoided; by designing the gear adjusting device, the tapping gear binding post is prevented from being affected by rainwater, moisture and foreign matter falling into or adhering to the tapping gear binding post, a good protection effect is achieved on the tapping gear binding post, and gear adjustment is not affected. The mutual inductor is installed by designing the mutual inductor fixing device,installation is convenient, and the structure is stable.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a dry-type transformer. Background technique [0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, and wharf CNC machinery and equipment. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. It has the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise. [0003] However, there are still many problems in the existing dry-type transformers: 1. Many power distribution rooms are located in dark and humid basements, and condensation will occur on the ceiling of the power room. When the indoor dry-type transformer does not have a casing, the condensation will It may fall on the transformer body, causing the transformer to have the risk of breakdown and burning. 2. Espe...

Problems solved by technology

[0003] However, there are still many problems in the existing dry-type transformers: 1. Many power distribution rooms are located in dark and humid basements, and condensation will occur on the ceiling of the power room. When the indoor dry-type transformer does not have a casing, the condensation will It may fall on the transformer body, causing the transformer to have the risk of breakdown and burning. 2. Especially the terminals of the dry-type transformer should avoid the influence of rain, moisture and foreign matter falling or adhering, otherwise it may cause serious damage. Electric accidents, and, while protecting the terminal, how to not affect the adjustment of the terminal position is also a difficult point at present; 3. Based on the consideration of electricity safety, many areas require to increase the input or output of the dry-type transformer. In order to monitor the operation of the transformer in real time, the installation of the current transformer is cumbersome and the structure is unstable after installation
