During the operation of power transformers, if there is an abnormal temperature, the principle of "first identifying the cause, then classifying and handling, and finally shutting down for troubleshooting" should be followed to prioritize equipment safety and avoid the expansion of faults.

Power transformer is a kind of static electrical equipment that realizes AC voltage conversion through electromagnetic induction principle. It is used to convert AC power of a certain voltage level into electric power of another voltage level with the same frequency. It is the core equipment for power transmission, distribution and use in power system.

8 main reasons for transformer burnout and how to prevent transformer burnout

The global explosion of AI computing power has triggered a "power equipment shortage," with once-obscure transformers becoming a "hard currency" in high demand in the international market. As the world's largest transformer producer, China, leveraging its complete industrial chain advantages, rapid delivery capabilities, and high cost-effectiveness, has seen its products sweep across markets in Europe, America, Southeast Asia, the Middle East, and Latin America. In 2025, exports reached 64.6 billion yuan, a year-on-year surge of 35.6%; in the first two months of 2026, exports increased by another 41%-61%, with exports to the US soaring by 182% and exports to Europe surging by 138%. Leading companies have orders booked until the end of 2027-2028, creating a scene of "global scramble for goods and long queues for orders."

As a key piece of equipment in power transmission, Box Type Sustations are widely used in various scenarios such as residential communities, industrial and mining enterprises, and public buildings due to their advantages of integration, miniaturization, and mobility. From the mature and stable European-style Box Type Sustations to the efficient and convenient American-style Box Type Sustations, and then to the innovative adaptations of domestically produced Box Type Sustations, my country's prefabricated substation industry has undergone multiple iterations, gradually forming a product system that adapts to different needs. At the same time, it also faces pressing issues such as fire prevention and capacity expansion.
