Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, and particularly relates to a high-power vehicle-mounted potted vertical flat transformer base. Background Art
[0002] In power systems and industrial applications, high-power transformers are core components used to transform voltage, current, and impedance. However, in the design of traditional high-power transformers, in order to ensure structural stability and electrical insulation performance, epoxy boards are often used to fix the base. Although this approach enhances the mechanical strength and safety of the transformer, it also brings problems such as large volume and heavy weight, seriously hindering its development towards miniaturization and lightweight. The epoxy board itself has a certain thickness and weight, and combining it with the transformer base will increase the volume and weight of the entire device. In addition, the production and processing cost of the epoxy board is relatively high, and together with its additional weight and volume, the overall cost of the high-power transformer increases, affecting the market competitiveness of the product.
