Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a dry-type transformer. Background Technology

[0002] Dry-type transformers are power transformers used for power distribution and conversion. They are characterized by the absence of liquid insulating medium between the windings and the core, instead using solid or dry insulating materials. This reduces fire and environmental risks, making them particularly useful in locations requiring higher safety standards, such as buildings and underground facilities. Furthermore, because they do not contain insulating oil, dry-type transformers eliminate the risk of oil leakage, which also results in typically lower maintenance costs.

[0003] The fixed base typically used for dry-type transformers makes movement during installation difficult. Therefore, large machinery is needed to lift and adjust the height, which increases labor costs and installation difficulty. At the same time, the transformer body lacks external protection, which reduces safety and maintenance efficiency.

[0004] Therefore, it is necessary to provide a dry-type transformer to solve the above-mentioned technical problems. Utility Model Content
