[0002] The dry-type power transformer is an important equipment that plays a key role in the power system. It uses air as the cooling medium. Compared with traditional oil-immersed transformers, it has significant advantages such as good fire resistance, no pollution, and easy installation and maintenance. The core of the dry-type transformer is usually stacked with high-magnetic permeability silicon steel sheets, and the winding is wound with high-quality copper or aluminum wires. During operation, the dry-type transformer can convert the input high voltage into the low voltage required by the user, realizing the effective transmission and distribution of electric energy. It has good overload capacity and short-circuit resistance, and can adapt to complex changes in power load. Since dry-type transformers do not require oil storage facilities and occupy a small area, they are suitable for places with high requirements for fire protection and explosion protection, such as high-rise buildings, commercial centers, hospitals, airports, etc. With the continuous advancement of technology, the performance of dry-type power transformers continues to improve, providing a strong guarantee for the stable operation and reliable power supply of the power system;
