Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically a universal housing for assembled transformers. Background Technology
[0002] Dry-type transformers are transformers that rely on air or special insulating materials for cooling. Because they do not require insulating oil or gas, they have advantages such as being environmentally friendly and having low maintenance costs, and are widely used in scenarios with strict fire protection requirements.
[0003] The transformer casing is an important component that protects the internal structure of the transformer and improves its safety. Existing general transformer casings are usually box structures made of multiple welded panels. After welding, the overall size of the transformer casing is large, which is inconvenient for transportation and handling, and there is also the problem that it cannot be installed as a whole in many installation sites. On-site welding is time-consuming and labor-intensive, increasing the labor intensity of workers. Therefore, there is a need to provide a modular general-purpose transformer casing to solve the above problems. Utility Model Content
