[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of a primary coil, a secondary coil, and an iron core. The transformer is the basic equipment for power transmission and distribution. Its main function is to convert AC power of one voltage and current into another voltage and current of the same frequency. Its specific functions include voltage conversion, current conversion, voltage stabilization, etc. Therefore, transformers are used in many fields.

[0015] (2) The connection and installation of the heat conducting sheet is completed by using the adhesive layer, and then the mounting plate is installed on the outside of the transformer. At this time, the heat conducting sheet is first used for contact heat conduction, and then the square heat conducting plates are fixed on the front and back of the inner wall of the mounting plate.
