Description

Technical Field

[0001] The utility model relates to the field of oil-immersed transformers, in particular to an oil-immersed transformer with good explosion-proof performance. Background Art

[0002] The oil-immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional wound core has three core columns arranged in an equilateral triangle, and there is no air gap in the magnetic circuit. The winding is tighter, and the three magnetic circuits are of the same length and the shortest. The cross-sectional area of ​​the core column is closer to a circle, so the performance is further improved. In the prior art, a Chinese patent document with application number CN202111168655.6 records an oil-immersed explosion-proof transformer. The patent uses a sealing ring to prevent the oil inside the oil tank from entering the inside of the core. , to prevent the oil from flowing into the gap between the iron core and the upper iron yoke during the use of the device, causing accidents to the iron core during use; through the cooperation of the pressure block and the first compression spring, the pressure block can be squeezed by the first compression spring and the second compression spring on the surface of the sealing ring to make the sealing ring close to the surface of the iron core, further reducing the possibility of oil leakage and preventing accidents; through the limit buckle, when the device is disassembled and repaired, the pressure block will not be ejected from the device due to the squeezing of the first compression spring, causing the device parts to be damaged and unusable, and facilitating the disassembly and assembly of the device. When the device is in use, the rear surface is usually close to the wall or column, resulting in a small ventilation area. Through the cooperation of the ventilation grille and the cooling fan, the air flow on the rear surface of the device is improved to prevent the temperature from concentrating and burning the internal parts. An existing oil-immersed explosion-proof transformer with explosion-proof function cannot adjust the installation position during use, affecting construction and installation, and dust is easily accumulated on the surface of the heat dissipation fins. If it is not cleaned for a long time, it is easy to affect the use, which brings certain adverse effects to people's use process. For this reason, we propose an oil-immersed transformer with good explosion-proof performance. Utility Model Content
