Description

Technical Field

[0002] Distribution transformer refers to a static electrical device that transforms AC voltage and current according to the law of electromagnetic induction in the power distribution system to transmit AC power. In some areas, power transformers with voltage levels below 35 kV (mostly 10KV and below) are called "distribution transformers", or "distribution transformers" for short. Distribution transformers should be installed on poles or on the ground in the open air.

[0003] When the distribution transformer is in operation, the internal electrical components will generate a lot of heat and vibrate during operation. Currently, the heat dissipation method of the existing distribution transformer is mostly natural air cooling. When used in a high temperature environment, natural air cooling cannot meet the heat dissipation requirements of the transformer, causing the distribution transformer to overheat and be damaged. In addition, after a long period of vibration, the fixed parts of the transformer will also age, greatly reducing its service life. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-5 A multifunctional distribution transformer comprises a bottom plate 1, which is rectangular and made of metal material. The bottom plate 1 made of metal material has higher strength, is not easily deformed or damaged after being subjected to force, and is more durable. The inner wall of the bottom plate 1 is slidably connected to a limit shaft 2, the top of the limit shaft 2 is fixedly connected to a fixed plate 3, the top surface of the fixed plate 3 is fixedly connected to a transformer body 4, the surface of the transformer body 4 is fixedly connected to a heat dissipation fin 5, the inner wall of the heat dissipation fin 5 is fixedly connected to a circulation pipe 6, the bottom surface of the bottom plate 1 is fixedly connected to a liquid storage tank 7, a water circulation mechanism is arranged inside the liquid storage tank 7, and the water circulation mechanism is composed of a liquid inlet bellows 8, a return bellows 9 and a water pump 10. The liquid inlet bellows 8 is fixedly connected to the inner wall of the liquid storage tank 7, and the liquid outlet end of the liquid inlet bellows 8 is fixedly connected to the liquid inlet end of the circulation pipe 6, the reflux bellows 9 is fixedly connected to the inner wall of the liquid storage tank 7, and the liquid inlet end of the reflux bellows 9 is fixedly connected to the liquid outlet end of the circulation pipe 6, the water pump 10 is fixedly connected to the inner wall of the liquid inlet bellows 8, and the water pump 10 is fixedly connected to the top surface of the liquid storage tank 7, which is used to suck the cooled coolant to circulate along the inner wall of the circulation pipe 6 to quickly absorb heat, so as to facilitate the rapid heat dissipation and cooling of the transformer body 4. A refrigeration component is arranged inside the liquid storage tank 7, an elastic damping mechanism is arranged on the top surface of the bottom plate 1, and a liquid changing component is arranged inside the liquid storage tank 7.

[0022] Specifically, the refrigeration component is composed of a semiconductor refrigeration sheet 11, a wind hood 12 and a heat dissipation fan 13. There are multiple semiconductor refrigeration sheets 11, and the multiple semiconductor refrigeration sheets 11 are all located inside the liquid storage tank 7, which are used to reduce the temperature of the coolant and improve the refrigeration efficiency. The semiconductor refrigeration sheet 11 is fixedly connected to the inner wall of the liquid storage tank 7, the wind hood 12 is fixedly connected to the surface of the liquid storage tank 7, and the heat dissipation fan 13 is fixedly connected to the inner wall of the wind hood 12, which is used to cool and cool the coolant in the liquid storage tank 7, so as to facilitate the rapid cooling of the transformer body 4 by the low-temperature coolant.

[0023] Specifically, the elastic damping mechanism is composed of a spring 14 and a rubber damping ring 15. The spring 14 is fixedly connected to the top surface of the base plate 1, and the spring 14 is fixedly connected to the bottom surface of the fixed plate 3. The rubber damping ring 15 is fixedly connected to the inner wall of the base plate 1, and the inner wall of the rubber damping ring 15 is slidably connected to the surface of the limit shaft 2. The friction force generated by the extrusion rebound of the spring 14 and the rubber damping ring 15 is convenient to reduce and offset the vibration force generated by the transformer body 4, thereby improving the vibration reduction performance.

[0024] Specifically, the liquid exchange component consists of a liquid exchange tube 16 and a solenoid valve 17. The liquid exchange tube 16 is fixedly connected to the inner wall of the liquid storage tank 7, and the solenoid valve 17 is fixedly connected to the inner wall of the liquid exchange tube 16, which is used to inject coolant into the liquid storage tank 7 and facilitate the replacement of the coolant.

[0025] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0026] When in use: first open the solenoid valve 17 to inject the coolant into the liquid storage tank 7 through the liquid exchange pipe 16. When the transformer body 4 generates vibration during operation, the vibration force pushes the limit shaft 2 to slide downward along the bottom plate 1 and the inner wall of the rubber damping ring 15 through the fixed plate 3, and at the same time squeezes the spring 14. The rebound force generated by the spring 14, combined with the friction force generated by the sliding of the rubber damping ring 15 and the limit shaft 2, can reduce and offset the vibration force generated by the transformer body 4. At the same time, the heat generated by the operation of the transformer body 4 is transferred to the heat dissipation fins 5, and the semiconductor refrigeration sheet 11 is started to absorb and release heat. The heat of the coolant in the liquid storage tank 7 is absorbed by the heat absorbing end of the semiconductor refrigeration plate 11 to perform cooling and cooling work, the heat dissipation fan 13 is started to dissipate heat from the heat releasing end of the semiconductor refrigeration plate 11, and the water pump 10 is started to drive the coolant to circulate along the inner wall of the circulation pipe 6 through the liquid inlet bellows 8. The heat in the heat dissipation fins 5 is absorbed by the low-temperature coolant, and the low temperature is transferred to the transformer body 4 through the circulation pipe 6 and the heat dissipation fins 5, so that rapid cooling and heat dissipation work can be performed. After the coolant absorbs heat, it flows back to the liquid storage tank 7 through the reflux bellows 9, and the circulation cooling and cooling work can be performed.

[0027] To summarize, the multifunctional distribution transformer opens the fluid replacement component to inject the coolant into the fluid storage tank 7. The transformer main body 4 generates vibration during operation, and pushes the limit shaft 2 to slide downward along the bottom plate 1 through the fixed plate 3 to squeeze the elastic damping mechanism. The vibration force is reduced by the rebound force and friction force generated by the elastic damping mechanism. The refrigeration component is started to reduce the coolant temperature. The water circulation mechanism is started to drive the coolant to circulate through the circulation pipe 6 and the heat dissipation fins 5 to quickly cool down and dissipate the heat of the transformer main body 4, thereby achieving the goal of facilitating the multifunctional vibration reduction and heat dissipation protection of the distribution transformer, avoiding the vibration force and heat generated by the operation of the transformer, which may cause the transformer to be easily overheated and damaged in a high temperature environment, and the service life of the transformer fixed parts is reduced. It is used to solve the problems raised in the above-mentioned background technology.
