High-temperature faults in transformers are not simply caused by the heat resistance of materials; more than 80% of power supply abnormalities stem from heat accumulation resulting from defective heat dissipation structural designs.
Abnormalities and potential hazards that may arise from the overheating transformer
To achieve precise voltage output throughout the entire life cycle of the transformer and prevent long-term parameter drift, the key does not lie in merely optimizing the winding resistance, but rather in reducing the iron core's magnetic hysteresis loss from all dimensions including materials, structure, design, and process. This is to stabilize the magnetic circuit operation state and lock in the long-term output accuracy.
Hysteresis loss in transformer directly affects the output accuracy.
The power frequency low-frequency transformers, with their electromagnetic coupling buffering characteristics, magnetic circuit energy storage voltage stabilization capabilities, and electrical isolation protection advantages, inherently possess the ability to resist voltage fluctuations.
The anti-voltage fluctuation capability of the power frequency transformer ensures stable power supply
In the design system of power frequency transformers, the number of turns in the windings is not merely a basic parameter for meeting the voltage ratio requirements. Instead, it is the sole core variable that can be adjusted in both directions to control copper loss and iron loss, thereby achieving the minimization of total loss.
The design of the number of windings directly affects the balance between copper and iron loss in the transformer
