Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of transformers, and more particularly relates to a novel ceramic insulation oil-immersed transformer. BACKGROUND

[0002] The oil-immersed transformer is a kind of power equipment taking insulation oil as insulation and heat dissipation medium, and the core is to realize insulation protection and heat dissipation of the transformer coil through the insulation oil to ensure the stability of power conversion and transmission.

[0003] At present, the oil-immersed transformer has at least the following technical problems: First, the oil-immersed transformer faces severe operation challenges in plateau and other low-temperature environments. The temperature difference between day and night in these areas is very large, and the temperature often drops to minus several dozen degrees Celsius at night. The internal insulation oil will have a sharp increase in viscosity under the action of continuous low temperature, and even directly coagulate into a solid state. As the core medium of the transformer, the insulation oil not only bears the insulation function of isolating the transformer coil and the shell to prevent short circuit, but also shoulders the heat dissipation responsibility of absorbing the heat generated by the coil during work and dissipating it. Once the viscosity of the insulation oil increases sharply or coagulates, its flowability will be completely lost, which not only cannot circulate and transfer heat in the transformer, causing the heat generated by the coil to be unable to dissipate in time, resulting in continuous temperature rise in the local area, accelerating the aging of the insulation material; but also loses the insulation protection effect, greatly reducing the insulation performance between the coils and between the coil and the shell, and easily causing short circuit and other faults, seriously threatening the safe operation of the transformer.

[0004] Second, in the plateau and other low-temperature environments, the traditional oil-immersed transformer has obvious limitations in heat preservation. The temperature in these areas drops sharply at night, and there is a lack of continuous heat source. The traditional oil-immersed transformer does not have a special heat preservation design and cannot effectively block the exchange of internal and external low temperatures. When there is no light at night, the environmental temperature drops rapidly, and the traditional structure is difficult to reduce the heat loss of the insulation oil, resulting in a sharp drop in the temperature of the insulation oil along with the environment. Due to the lack of targeted heat preservation measures, the insulation oil is easy to lose the appropriate viscosity due to low temperature, and even coagulate, thereby failing to normally play the insulation protection role on the transformer coil and being difficult to efficiently transfer the heat generated by the coil. The lack of heat preservation capacity makes it difficult for the traditional oil-immersed transformer to maintain the stable state of the insulation oil at night in low temperature, and aggravates the instability of the equipment operation, which cannot meet the special requirements of the plateau and other low-temperature environments on the heat preservation performance of the transformer.

When the light sensor on the heat exchange tank insulation board 3 senses external sunlight, the third sleeve 19 drives the second push rod 20 to move outward, which can drive the heat collection plate composed of the heat exchange tank insulation board 3 and the light heat collection plate 5 to expand, and part of the light heat collection plate 5 expands to collect heat. When the light sensor on the heat exchange tank insulation board 3 detects that there is no external sunlight, the heat exchange oil tank 2 moves inward to retract the heat collection plate. At this time, the light heat collection plate 5 can effectively insulate the insulating oil in the transformer shell 1. The rotation of the third gear 16 can drive the fourth gear 25 to rotate, and the rotation of the fourth gear 25 can drive the rotating fixed plate 7 to rotate synchronously. The rotation of the rotating fixed plate 7 can control the heat collection plate composed of the light heat collection plate 5 and the heat exchange tank insulation board 3 to expand and retract.

[0019] The heat storage and exchange mechanism includes an insulating oil exchange channel 4. The insulating oil exchange channel 4 is internally provided with a channel for exchanging insulating oil. One end of the insulating oil exchange channel 4 is fixedly connected with an external oil storage tank 18, and the other end of the insulating oil exchange channel 4 is fixedly connected with a main oil storage tank 22. The insulating oil exchange channel 4 is designed as a sleeve. The insulating oil exchange channel 4 is used to exchange insulating oil at different temperatures in the main oil storage tank 22 and the external oil storage tank 18. A space is formed at the lower end of the transformer shell 1. The insulating oil exchange channel 4 is installed in the space formed at the lower end of the transformer shell 1. A valve body is arranged at the connection between the insulating oil exchange channel 4 and the heat oil tank 2. When the heat oil tank 2 collects enough heat outside during the day, the valve body is opened when the heat oil tank 2 returns to the inside of the transformer shell 1. Because the insulating oil with a higher temperature rises and the insulating oil with a lower temperature falls, the insulating oil in the external oil storage tank 18 exchanges heat with the insulating oil in the space composed of the main oil storage tank 22 and the partitioning and sealing plate 21 through the pipeline in the insulating oil exchange channel 4, so as to prevent the insulating oil in the transformer shell 1 from condensing due to a too low temperature at night, which affects the transformer coil 23.

[0020] Working principle: When the light sensor on the heat exchange tank insulation board 3 detects sunlight, the expansion mechanism is started. The third sleeve 19 pushes the second push rod 20 to slide in the sliding groove. The second push rod 20 drives the heat oil tank 2 to move outward. At the same time, the first push rod 9 slides in the sliding groove in the first sleeve 8. Because the threaded sliding groove 10 on the first push rod 9 is engaged with the sliding block of the second sleeve 11, the second sleeve 11 drives the first gear 12 to rotate. The first gear 12 engages the second gears 14 on both sides. The second gears 14 drive the third gears 16 to rotate through the first shaft 15. The gear reversing mechanism of one of the first shafts 15 makes the two third gears 16 rotate in opposite directions, which prepares for the expansion of the light heat collection plate 5.

[0021] In the second step, the third spur gear 16 drives the fourth spur gear 25 to rotate through the first transmission belt 24, and the fourth spur gear 25 drives the fifth spur gear 28 to rotate through the second rotating shaft 26 and the second transmission belt 27. The fifth spur gear 28 rotates the rotating fixed plate 7 through the rotating shaft 6, and finally drives the light heat collection plate 5 to unfold. The graphene-based thermal conductive coating on the outside of the light heat collection plate 5 absorbs solar energy and conducts heat to the external oil storage tank 18 to heat the internal insulating oil.

[0022] In the third step, the light sensor detects that the sunlight has ended, and the deployment mechanism runs in reverse. The second push rod 20 drives the heat exchange oil tank 2 to be retracted into the main oil storage tank 22. The first push rod 9 slides in the opposite direction in the first sleeve 8. The gear and the transmission belt drive in the opposite direction to reverse the light heat collection plate 5. At this time, the heat exchange box insulation plate 3 faces inward, and its rock wool material is used to insulate the insulating oil in the main oil storage tank 22 and the external oil storage tank 18, further preventing the insulating oil from condensing due to low temperature, and ensuring the normal operation of the transformer coil 23.

[0023] In the fourth step, when the heat exchange tank 2 returns to the interior of the transformer housing 1, the valve on the insulating oil exchange passage opens, connecting the external oil tank 18 and the main oil tank 22. The heated insulating oil in the external oil tank 18 rises in temperature and then flows through the insulating oil exchange passage 4 into the main oil tank 22. The cooler insulating oil in the main oil tank 22, due to its higher density, drops in temperature and flows through the insulating oil exchange passage 4 into the external oil tank 18. This process utilizes the principle that "hotter insulating oil rises in temperature" to achieve a cyclic exchange of insulating oil between the external oil tank 18 and the main oil tank 22, ensuring a stable insulating oil temperature in the main oil tank 22 at night.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
