AI Technical Summary

Technical Problem

During the operation of a transformer, if the temperature sensor detects that the temperature exceeds the set value, uneven cooling by air will hinder heat transfer on the winding surface, and vibration may cause insulation aging and poor contact.

Method used

The design of the three-dimensional wound transformer with alloy iron core enhances the contact area and turbulence intensity between airflow and winding surface by setting staggered S-shaped guide plates and angle adjustment mechanisms on the inner and outer sides of the insulator. The annular guide mechanism and shock absorption mechanism ensure uniform heat dissipation and reduce the impact of vibration.

Benefits of technology

It improves the cooling rate and equipment reliability, avoids insulation aging and poor contact caused by vibration, and ensures uniform heat dissipation and stable operation of the transformer.
