Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a transformer with convenient replacement of insulating pads. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components include a primary coil, a secondary coil, and an iron core (magnetic core). In the existing patent application with application number CN202123198720.8, a transformer that is convenient for replacing insulating pads is proposed. Although it uses the design of an auxiliary fixing component to replace the fixing screws connected to the top side of the sealing cover with multiple auxiliary fixing components, it only needs to use the fixing screws to position and limit the four corners, and then use the auxiliary fixing components for auxiliary fixing to complete the sealing of the transformer body. The convenience of unlocking the auxiliary fixing components makes it easier to disassemble and fix the sealing cover and the transformer body, so that it is more convenient to replace the insulating plate. However, the operation steps are still relatively complicated, so that the disassembly and fixing efficiency between the sealing cover and the transformer body still needs to be improved, so it needs to be improved, so that the insulating pad of the transformer is easier to replace.
