Three-Dimensional Temperature Field Simulation and Analysis of Natural Oil Circulation Transformer

The temperature inside the transformer box can reflect its real-time operating status, so the temperature variation can be used to judge the safe operation of the transformer. The tank, iron core and winding of a natural oil circulation transformer are simulated and calculated, so that the temperature field distribution is obtained, which provides a reference for studying the running state of the transformer. It can be concluded that the transformer winding and core temperature are significantly higher than the transformer box temperature at the same height; the transformer winding temperature is higher than the core temperature, and the low-voltage winding temperature is the highest.
