Why Does The Temperature Rise Problem Occur In Constant Voltage Transformers?

During operation, 3 phase constant voltage transformer may experience an abnormal temperature rise. This condition means that the internal heat accumulates beyond what can be dissipated, which can have an adverse effect on components such as winding insulation.

constant voltage transformer for home's heat primarily originates from load losses and core losses. Heat is naturally generated during operation, but if the load exceeds the rated capacity or the operating environment has poor ventilation, heat accumulation accelerates, leading to a continuous rise in internal temperature. Thermal cycling effects may also affect the performance of insulation materials, causing secondary faults such as aging, open circuits, or short circuits.
