Description

Technical Field

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

[0002] Dry-type earthed transformers are a type of transformer used in an insulation system where the windings and core do not require any liquid cooling medium (such as oil). Instead, they use dry insulating materials (usually resin or similar materials) to insulate the windings and core. This type of transformer is often used in applications that require a high degree of safety and environmental friendliness, as they do not leak liquid insulating media during use.

[0003] In outdoor environments, transformers are core equipment for power transmission. Since they have high-voltage and low-voltage sides, lightning protection measures must be fully considered to ensure the safe operation of the transformer itself. Given that traditional lightning rods may not be able to cope with a variety of lightning weather conditions, in actual applications, it is necessary to flexibly adjust the size and height of lightning rods according to actual meteorological conditions in order to accurately detect and optimize the lightning protection effect. This adjustment process not only enhances the adaptability and reliability of the lightning protection system, but also improves the protection capabilities of the transformer and its surrounding facilities.

[0004] Therefore, there is an urgent need to provide a dry-type grounding transformer to solve the above problems. Utility Model Content
