Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a high-efficiency oil-circulating cooling transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the magnetic core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). There are many ways to cool a transformer, including cooling by circulating oil outside the transformer.

[0003] In existing technologies, traditional transformers with external oil circulation cooling typically have their heat sinks directly fixed to the outside of the transformer. This method makes it difficult to quickly disassemble the heat sinks when they are damaged or blocked, hindering repairs or replacements and affecting the normal operation of the transformer oil circulation cooling. Furthermore, the heat sinks are generally not protected, reducing the transformer's safety and convenience. Utility Model Content
