[0002] Oil-immersed power transformers are a type of electrical equipment that uses mineral insulating oil as a cooling and insulating medium and are widely used in power transmission and distribution systems. Their core consists of an iron core and windings, and the oil tank is filled with transformer oil. These transformers have the characteristics of good insulation performance, strong overload capacity, and stable operation. Compared with dry-type transformers, they are lower in cost and more suitable for large-capacity scenarios. They are mainly used in substations, industrial and mining enterprises, and other places. They are key equipment for realizing voltage conversion and power distribution in power systems.

[0003] The oil-immersed power transformers currently in use still have the following problems: 1. Generally, there is a lack of corresponding installation structure, which makes it inconvenient to quickly connect to poles with different spacings. In addition, the power transformer is prone to position deviation after installation, resulting in uneven force on the installation structure. 2. The insulating oil is usually located inside the power transformer, and it is impossible to circulate and cool the insulating oil through the heat sink, which reduces the heat dissipation effect of the power transformer; 3. When replacing the insulating oil, the impurities on the inner wall of the power transformer cannot be cleaned by the remaining insulating oil, which affects the replacement effect of the insulating oil; and it is inconvenient for the staff to quickly clean the heat sink of the power transformer, which increases the difficulty of cleaning the heat sink of the power transformer.
