Description

Technical Field

[0001] The utility model belongs to the technical field of electronic components, and in particular relates to a transformer cabinet. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The transformer is usually placed inside a cabinet and then hoisted as a whole through a hoisting cabinet. Therefore, the overall hoisting strength of the transformer and cabinet needs to be considered when designing the transformer cabinet.

[0003] In the prior art, the transformer cabinet and the transformer inside it are only connected and fixed by fixing bolts at the bottom of the transformer. When hoisting, it is hoisted through the lifting rings on the top of the cabinet. The hoisting force only acts on the cabinet and cannot act on the transformer inside the cabinet. The overall hoisting strength is low. In addition, this cabinet structure and hoisting method require the cabinet itself to have a greater structural strength, which usually results in a heavier overall weight of the cabinet, which is not only not conducive to product hoisting, but also increases the production cost of the cabinet.
