AI Technical Summary

Technical Problem

Traditional high-voltage test reactors have poor heat dissipation performance, resulting in high manufacturing costs and difficulties in controlling operating noise. Existing tank-type iron-core reactors have low thermal conductivity due to the epoxy resin insulating outer cylinder, requiring a large amount of transformer oil or an increase in coil wire diameter to extend operating time.

Method used

A heat exchange jacket made of elastic material is installed around the iron ring of the tank-type iron-core reactor. It achieves efficient heat dissipation through water circulation. The outer layer is corrugated to increase the contact area with the transformer oil. The water pump is turned on during reactor operation for circulating heat exchange.

Benefits of technology

It significantly improves the heat dissipation performance of the reactor, reduces the amount of coil materials and transformer oil used, lowers manufacturing costs, and extends operating time.
