AI Technical Summary
Existing transformer cooling systems are not ideal for heat dissipation under heavy power loads or prolonged high temperatures, and cannot reliably control transformer temperature for extended periods, resulting in deteriorated operating performance.
The transformer heat dissipation device includes first and second heat dissipation fins and three sets of heat dissipation fan units. It achieves two-stage heat dissipation by using oil-immersed self-cooling heat dissipation in conjunction with the fan units. The fan units are used to carry heat from the fins to the top of the transformer and blow it out horizontally.
It improves heat dissipation efficiency, enhances the load capacity of transformers, extends equipment life, reduces operating losses and failure risks, and improves operational stability and flexibility.
