Description

Technical Field

[0001] This utility model relates to the field of voltage transformer technology, and more specifically, to a high-voltage wiring device for a voltage transformer used in combined electrical appliances. Background Technology

[0002] Voltage transformers are important measuring components in combined electrical appliances, while high-voltage connection devices are key equipment for ensuring the correct and safe connection between voltage transformers and high-voltage circuits. They ensure the accuracy of voltage measurement in the power system, thereby guaranteeing the safe and stable operation of the power system.

[0003] In the existing technology, the contact and the contact seat achieve elastic contact under the elastic force of the spring, which does not achieve a completely rigid connection. During transportation, the contact and the contact seat will vibrate and rub against each other. Vibration and friction cause wear on the contact and the contact seat, which can easily lead to partial discharge failure of the equipment and affect the safe operation of the equipment.

[0004] A search revealed that Chinese patent CN201886888U discloses a high-voltage wiring device for a voltage transformer used in combined electrical appliances. This device fixes a shielding cylinder to the central conductor of an insulator. One end of a conductor is connected to the central conductor of the insulator, and the other end is fixed to the upper end of a conductive rod. The lower end of the conductive rod is fixed to the coil shield. The central conductor of the insulator and the coil shield are equipotentially connected through the conductive rod and conductor, achieving a flexible connection. This solves several potential problems associated with the original structure, such as electrical connection failure due to vibration and friction during transportation. The device features a simple structure, easy component processing and assembly, and high electrical connection reliability.

[0005] However, in actual use, this structure is quite complex, and the installation process in the combined electrical appliance is cumbersome, requiring a lot of on-site installation. Furthermore, the height and tilt angle of the voltage transformer cannot be adjusted according to the actual situation, which affects the performance. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-voltage wiring device for a voltage transformer for combined electrical appliances, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-voltage wiring device for a voltage transformer in a combined electrical appliance includes a housing. An oil tank is fixedly installed inside the housing. An inlet pipe is passed through the top of the oil tank, and a sealing cap is snapped onto the top of the inlet pipe. Two porcelain sleeves are passed through the top of the oil tank, and an oil storage cylinder is passed through one end of each of the two porcelain sleeves. An adjustment mechanism is provided at the bottom of the housing. The adjustment mechanism includes a fixed plate fixedly installed at the bottom of the housing. Two fixed sleeves are fixedly installed on both sides of the fixed plate. Two threaded grooves are formed on the surface of each of the two fixed sleeves. Threaded posts are threaded into the interior of each of the two threaded grooves. A handle is fixedly installed at one end of each threaded post, and a clamping plate is rotatably connected to the other end of the threaded post. The clamping plate is arc-shaped, and a rubber layer is fixedly installed on one side of the clamping plate.

[0009] By adopting the above technical solution, the height of the outer casing can be adjusted more easily, making it easier to achieve precise docking with the connected equipment, facilitating later inspection and maintenance, and reducing the difficulty and workload of operation.

[0010] As a further description of the above technical solution: each of the plurality of fixing sleeves is fitted with a fixing post, the bottom of the fixing post is fixedly provided with a base plate, the surface of the fixing post is fixedly provided with an anti-slip layer, the anti-slip layer is made of soft rubber material, the top of the ceramic sleeve is fixedly provided with a first terminal, and a connecting piece is threaded to one side of the first terminal.

[0011] By adopting the above technical solution, stability can be further enhanced, thereby improving the effectiveness of use.

[0012] As a further description of the above technical solution: a second terminal is threadedly connected to one side of the connecting piece, a first insulating layer is fixedly disposed on the outside of the connecting piece, and a second insulating layer is fixedly disposed on the outside of the outer shell. Both the first insulating layer and the second insulating layer are made of nanocomposite insulating material.

[0013] By adopting the above technical solution, the electrical insulation performance of the device is guaranteed in order to withstand high voltage, prevent electrical breakdown and leakage.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting an adjustment mechanism, compared with the existing technology, holding the handle and rotating it in the forward direction will drive the threaded column to rotate in the forward direction, thereby driving the threaded column to rotate from the threaded groove opened on the surface of the fixed sleeve, which in turn drives the clamping plate to move away from the fixed column, thereby separating the clamping plate from the fixed column, and then driving the fixed sleeve to move up and down outside the fixed column, so as to adjust according to the actual situation. This allows for adjustment of the height of the four corners of the fixed plate, which facilitates the height adjustment of the outer shell, while also ensuring the stability of the outer shell, thereby ensuring accurate wiring and improving the performance.

[0016] 2. By setting up an inlet pipe, an oil storage tank, a first insulation layer, and a second insulation layer, compared with the existing technology, the insulating oil is poured into the oil tank through the inlet pipe by opening the sealing cover, and insulating oil is also added to the inside of the oil storage tank. Insulating oil is a good dielectric. Under high voltage environment, insulating oil can prevent discharge between components with different potentials, ensuring the insulation performance of the voltage transformer. Secondly, by setting up the first insulation layer and the second insulation layer, since both the first insulation layer and the second insulation layer are made of nano-composite insulating material, the nano-insulating material can withstand high voltage, prevent electrical breakdown and leakage, and ensure the efficient and stable conduction of high voltage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The embodiments disclosed in this application are as follows: Figure 1-5 The high-voltage wiring device for a voltage transformer in a combined electrical appliance includes a housing 1. An oil tank 2 is fixedly installed inside the housing 1. An inlet pipe 3 is passed through the top of the oil tank 2, and a sealing cap 4 is snapped onto the top of the inlet pipe 3. Two porcelain sleeves 5 are passed through the top of the oil tank 2, and an oil reservoir 6 is passed through one end of each of the two porcelain sleeves 5. An adjustment mechanism is provided at the bottom of the housing 1. The adjustment mechanism includes a fixing plate 7 fixedly installed at the bottom of the housing 1. Two fixing sleeves 8 are fixedly installed on both sides of the fixing plate 7. Two threaded grooves are formed on the surface of each fixing sleeve 8. Threaded posts 9 are threadedly connected to the interior of each threaded groove. A handle 10 is fixedly installed at one end of each threaded post 9, and a clamping plate 11 is rotatably connected to the other end of each threaded post 9. The clamping plate 11 is arc-shaped. One side of the clamping plate 11... A rubber layer 12 is fixedly installed. When the height of the outer shell 1 needs to be adjusted, or when the position where the outer shell 1 needs to be placed is uneven, hold the handle 10 and rotate it clockwise. This will cause the threaded post 9 to rotate clockwise, which will cause the threaded post 9 to rotate out of the threaded groove on the surface of the fixing sleeve 8. This will cause the clamping plate 11 to move, moving it away from the fixing post 13 and separating the clamping plate 11 from the fixing post 13. This will cause the fixing sleeve 8 to move up and down outside the fixing post 13, thus adjusting it according to the actual situation. At the same time, the fixing sleeves 8 at the four corners of the fixing plate 7 can also be operated in the same way, so that the height of the four corners can be adjusted, which will facilitate the height adjustment of the outer shell 1 and ensure the stability of the outer shell 1, thus ensuring accurate wiring.

[0025] Reference Figure 2-4As shown, each of the multiple fixed sleeves 8 has a fixed post 13 inside. The bottom of the fixed post 13 is fixedly provided with a base plate 14. The surface of the fixed post 13 is fixedly provided with an anti-slip layer 15, which is made of soft rubber. The top of the porcelain sleeve 5 is fixedly provided with a first terminal 16. A connecting piece 17 is threaded to one side of the first terminal 16. The sealing cover 4 is opened and the insulating oil is poured into the oil tank 2 through the feed pipe 3. Insulating oil is also added to the inside of the oil storage cylinder 6. The insulating oil is a good dielectric. Under high voltage conditions, the insulating oil can prevent the discharge phenomenon between components with different potentials, ensuring the insulation performance of the voltage transformer. When the 15 and 12 on one side of the fixed post 13 come into contact, the friction effect is increased, thereby improving the stability.

[0026] Reference Figure 5 As shown, a second terminal 18 is threadedly connected to one side of the connecting piece 17. A first insulating layer 19 is fixedly disposed on the outside of the connecting piece 17, and a second insulating layer 20 is fixedly disposed on the outside of the outer shell 1. Both the first insulating layer 19 and the second insulating layer 20 are made of nanocomposite insulating material. By setting the first insulating layer 19 and the second insulating layer 20, since both the first insulating layer 19 and the second insulating layer 20 are made of nanocomposite insulating material, the nano insulating material can withstand high voltage, prevent electrical breakdown and leakage, and ensure the electrical insulation performance of the device.

[0027] Working principle of this utility model:

[0028] This utility model relates to a high-voltage wiring device for a voltage transformer used in combined electrical appliances. In operation, the insulating oil is introduced into the oil tank 2 through the inlet pipe 3 by opening the sealing cover 4. Insulating oil is also added to the oil storage cylinder 6. The insulating oil, being an excellent dielectric, completely immerses the primary winding, secondary winding, and core components inside the porcelain bushing 5. Under high voltage conditions, the insulating oil prevents discharge between components at different potentials, ensuring the insulation performance of the voltage transformer. Furthermore, the insulating oil fills all the gaps inside the porcelain bushing 5, reducing the presence of air gaps. Since air has relatively low insulation strength, the presence of the insulating oil significantly improves the overall insulation level of the voltage transformer, enabling it to operate safely under high voltage. When the primary winding is connected to a high-voltage AC power supply, an AC current flows through the winding. This current generates an alternating magnetic flux in the core at the same frequency as the power supply, ensuring efficient and stable conduction of high-voltage electricity.

[0029] Simultaneously, the height of the outer casing 1 needs to be adjusted. If the outer casing 1 is not placed on an uneven surface, grip the handle 10 and rotate it clockwise. This will cause the threaded post 9 to rotate clockwise, rotating it from the threaded groove on the surface of the fixing sleeve 8. This will move the clamping plate 11 away from the fixing post 13, separating the clamping plate 11 from the fixing post 13. This will cause the fixing sleeve 8 to move up and down outside the fixing post 13, allowing for adjustment according to the actual situation. The fixing sleeves 8 at the four corners of the fixing plate 7 can also be operated according to the above steps, allowing for height adjustment of the four corners. This facilitates height adjustment of the outer casing 1 and ensures its stability, thus ensuring accurate wiring. Furthermore, by setting the first insulating layer 19 and the second insulating layer 20, both made of nanocomposite insulating material, which can withstand high voltage and prevent electrical breakdown and leakage, the electrical insulation performance of the device is guaranteed.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
