How to Approach Transformer Temperature Rise Reasonably?

Perspectives on temperature rise encompass various aspects essential for the long-term stable operation of transformers, specifically in the following dimensions:

Safety: The prudent control of temperature rise aims to ensure that the internal temperature of the transformer does not exceed safety limits. This measure is primarily intended to mitigate the risk of overheating, effectively preventing potential fire incidents or other malfunctions.

Efficiency: Careful temperature rise control contributes to improving the efficiency of transformers. During the design phase, the emphasis is typically on achieving the lowest possible temperature rise to reduce energy wastage and enhance overall energy efficiency. This ensures that transformers operate more economically and efficiently.

Lifespan: The judicious design of temperature rise levels can extend the lifespan of transformers. Excessive temperature rise may accelerate the aging of insulation materials, thereby reducing the equipment's longevity. Effective temperature rise control helps protect insulation materials, slowing down the aging process and enhancing the long-term reliability of the equipment.

In the comprehensive consideration of factors such as safety, efficiency, lifespan, and load capacity, the permissible temperature rise of transformers becomes a crucial parameter that requires careful balancing in the design process. Ensuring the optimal temperature rise level, while meeting all requirements, is essential to achieving the reliability and stability of transformers during prolonged operation.
