Technical Field

[0001] This invention relates to the field of solid-state transformer technology, specifically to a power supply protection device based on a solid-state transformer. Background Technology

[0002] Solid-state transformers are a combination of converters and transformers. Also known as smart transformers, they are a type of modern electrical energy equipment. Solid-state transformers use power electronic devices to replace traditional copper or aluminum coils to achieve the transmission and conversion of electrical energy. During use, solid-state transformers require protective equipment for protection.

[0003] Existing technologies, such as CN221149760U, describe a protective mechanism for a transformer. In this mechanism, a limiting block, under the elastic force of a first spring, is inserted into a hole in a fixing plate to fix the position of the sliding plate. The arc-shaped plate serves to shield against wind and rain, greatly reducing the possibility of rainwater contacting the transformer body.

[0004] However, there are still some shortcomings in the use of this institution: This structure is not suitable for providing overall protection for the transformer body. It only uses arc-shaped plates to shield against wind and rain, which can only protect certain areas. It lacks effective protective measures for other parts of the transformer body, such as the sides and back.

[0005] This structure makes it difficult to install transformers stably. There are no corresponding shock absorption and buffer devices for the vibration and shaking generated by the transformer during operation. After long-term use, the installation position of the transformer is prone to shift. Summary of the Invention
