Description

Technical Field

[0001] This application relates to the field of energy storage transformer technology, and in particular to a heat dissipation device for the outer shell of an energy storage transformer. Background Technology

[0002] As an indispensable part of modern power systems, energy storage transformer substations play a crucial role in energy storage and distribution. However, during transformer operation, due to load fluctuations, changes in ambient temperature, and the transformer's own operating characteristics, the temperature rise of the transformer can increase significantly, thus affecting the system's operational stability and safety.

[0003] Currently, transformer cooling primarily relies on traditional fan exhaust or natural convection methods. While these methods can help lower transformer temperatures to some extent, their cooling efficiency is low, especially under high temperature and high load conditions, and they cannot effectively prevent excessive temperature rise. Excessive temperature rise not only shortens the transformer's lifespan but can also lead to equipment damage and even safety hazards. Utility Model Content
