Description

Technical Field

[0001] This utility model relates to the field of gas relay technology, and more specifically, to a gas relay device and a transformer device having the same. Background Technology

[0002] A gas relay, also known as a gas-powered relay, is a device installed on the connecting pipeline between the transformer tank and the conservator. It is used to detect the accumulation rate of dissolved gas in the transformer oil, thereby determining internal transformer faults. When a serious fault occurs inside the transformer tank, it can serve as the main protection device for the transformer. It contains two floats, one upper and one lower. When a small amount of gas appears inside the transformer, the float will rise slightly; when a large amount of gas appears, the float will rise significantly. The upper float inside the relay will drive the transmission mechanism, causing the relay contacts to actuate, thereby sending a signal or disconnecting the faulty transformer. The relay has a simple structure, is sensitive, and reacts quickly, making it an extremely reliable device for transformer protection in power systems.

[0003] In related technologies, when replacing or installing a gas relay, the gas relay is subjected to tension from the metal bellows during the tightening process, which can easily cause the gas relay to crack. Utility Model Content

[0004] The main objective of this invention is to provide a gas relay device and a transformer device having the same, in order to solve the problem in related technologies where the gas relay is subjected to large tensile forces during installation, which leads to its easy damage.

[0005] To achieve the above objectives, according to one aspect of the present invention, a gas relay device is provided, comprising: a relay body; a first connecting pipe, including a first pipe body and a first flange connected to the first pipe body, the first flange being connected to a first end of the relay body; a second connecting pipe, including a second pipe body and a second flange connected to the second pipe body, the second flange being connected to a second end of the relay body; and a fixing structure, including a first clamping plate, a second clamping plate, and a first adjusting rod, wherein the first clamping plate is located on the side of the first flange away from the second flange, the second clamping plate is located on the side of the second flange away from the first flange, and the first adjusting rod is connected between the first clamping plate and the second clamping plate, the first adjusting rod being capable of adjusting the distance between the first clamping plate and the second clamping plate to clamp the first flange, the relay body, and the second flange.

[0006] Furthermore, the first clamping plate includes a first plate body and a first protrusion, and the second clamping plate includes a second plate body and a second protrusion. The first protrusion abuts against the first flange, and the second protrusion abuts against the second flange.

[0007] Furthermore, the first protrusion is located in the middle of the first plate body, and the second protrusion is located in the middle of the second plate body.

[0008] Furthermore, the length of the first protrusion is greater than the width of the first plate body; and / or, the length of the second protrusion is greater than the width of the second plate body.

[0009] Furthermore, the first adjusting rod includes a first threaded rod and a first fastening nut and a second fastening nut disposed on the first threaded rod. The first fastening nut is located on the side of the first clamping plate away from the first flange, and the second fastening nut is located on the side of the second clamping plate away from the second flange.

[0010] Furthermore, the fixing structure also includes a second adjusting rod, which is located between the first clamping plate and the second clamping plate, and the second adjusting rod and the first adjusting rod are spaced apart.

[0011] Furthermore, the fixing structure also includes a third clamping plate, a fourth clamping plate, a third adjusting rod, and a fourth adjusting rod. The third clamping plate is located on the side of the first flange away from the second flange, and the fourth clamping plate is located on the side of the second flange away from the first flange.

[0012] Furthermore, the fixing structure also includes a fifth adjusting rod and a sixth adjusting rod, with the fifth adjusting rod connected between the first clamping plate and the third clamping plate, and the sixth adjusting rod connected between the second clamping plate and the fourth clamping plate.

[0013] Furthermore, both the first and second adjusting rods are located between the fifth and sixth adjusting rods.

[0014] According to another aspect of the present invention, a transformer device is provided, including a gas relay mounting device, wherein the gas relay device is the gas relay device described above.

[0015] By applying the technical solution of this utility model, the first flange and the second flange are respectively connected to the relay body, thereby realizing the connection between the first connecting pipe and the second connecting pipe and the relay body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0027] like Figures 1 to 4 As shown, in this embodiment, the gas relay device includes: a relay body 10, a first connecting pipe 20, a second connecting pipe 30, and a fixing structure 40. The first connecting pipe 20 includes a first pipe body 21 and a first flange 22 connected to the first pipe body 21, the first flange 22 being connected to a first end of the relay body 10. The second connecting pipe 30 includes a second pipe body 31 and a second flange 32 connected to the second pipe body 31, the second flange 32 being connected to a second end of the relay body 10. The fixing structure 40 includes a first clamping plate 41, a second clamping plate 42, and a first adjusting rod 43. The first clamping plate 41 is located on the side of the first flange 22 away from the second flange 32, and the second clamping plate 42 is located on the side of the second flange 32 away from the first flange 22. The first adjusting rod 43 is connected between the first clamping plate 41 and the second clamping plate 42, and the first adjusting rod 43 can adjust the distance between the first clamping plate 41 and the second clamping plate 42 to clamp the first flange 22, the relay body 10, and the second flange 32.

[0028] Applying the technical solution of this embodiment, the first flange 22 and the second flange 32 are respectively connected to the relay body 10, thereby connecting the first connecting pipe 20 and the second connecting pipe 30 to the relay body 10. The fixing structure 40 includes a first clamping plate 41, a second clamping plate 42, and a first adjusting rod 43. The first clamping plate 41 and the second clamping plate 42 are located outside the first flange 22 and the second flange 32, respectively. That is, the first adjusting rod 43 can adjust the distance between the first clamping plate 41 and the second clamping plate 42, thereby connecting the first flange 22, the second flange 32, and the relay body 10 into a whole. Thus, during installation, when the second connecting pipe 30 applies a pulling force to the relay body 10, the pulling force is transmitted to the first connecting pipe 20 through the fixing structure 40. This prevents the pulling force from directly pulling the relay body 10, thereby preventing damage to the relay body 10. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the gas relay is subjected to a large pulling force during installation, leading to easy damage.

[0029] like Figures 1 to 4 As shown, in this embodiment, the first clamping plate 41 includes a first plate body 411 and a first protrusion 412, and the second clamping plate 42 includes a second plate body 421 and a second protrusion 422. The first protrusion 412 abuts against the first flange 22, and the second protrusion 422 abuts against the second flange 32. The first protrusion 412 allows a gap to be formed between the first plate body 411 and the first flange 22, enabling the operator to connect the relay body 10 and the first flange 22 through this gap. The second protrusion 422 has the same function as the first protrusion 412.

[0030] Specifically, the tightness of the connection is further improved by the cooperation between the first protrusion 412 and the first flange 22 and the second protrusion 422 and the second flange 32, making it suitable for high-load and high-vibration industrial environments.

[0031] like Figures 1 to 5 As shown, in this embodiment, the first protrusion 412 is located in the middle of the first plate body 411, and the second protrusion 422 is located in the middle of the second plate body 421. This layout design makes the overall structure more balanced, effectively disperses external forces, reduces local stress, and extends the service life of the equipment.

[0032] Specifically, by setting the first protrusion 412 in the middle of the first plate body 411 and the second protrusion 422 in the middle of the second plate body 421, not only can the stability of the structure be improved, but also the local stress concentration caused by external force can be effectively reduced, thereby extending the service life of the equipment.

[0033] like Figures 1 to 5As shown, in this embodiment, the length of the first protrusion 412 is greater than the width of the first plate body 411; the length of the second protrusion 422 is greater than the width of the second plate body 421. By increasing the length of the first protrusion 412 and the second protrusion 422, the contact area with the first flange 22 and the second flange 32 is increased, enhancing the connection's firmness, thereby making the connection between the gas relay device and the transformer more secure.

[0034] like Figures 1 to 5 As shown, in this embodiment, the first adjusting rod 43 includes a first threaded rod 431 and a first fastening nut 432 and a second fastening nut 433 disposed on the first threaded rod 431. The first fastening nut 432 is located on the side of the first clamping plate 41 away from the first flange 22, and the second fastening nut 433 is located on the side of the second clamping plate 42 away from the second flange 32. The design of the first threaded rod 431 makes the installation and disassembly process more convenient, reduces maintenance costs, and improves work efficiency.

[0035] like Figures 1 to 5 As shown, in this embodiment, the fixing structure 40 further includes a second adjusting rod 44, which is located between the first clamping plate 41 and the second clamping plate 42, and is spaced apart from the first adjusting rod 43. The addition of the second adjusting rod 44 further improves the stability of the connection, making it suitable for power systems requiring high reliability, such as nuclear power plants and aerospace equipment, ensuring the safe operation of power facilities under extreme conditions.

[0036] like Figures 1 to 5 As shown, in this embodiment, the fixing structure 40 further includes a third clamping plate 451, a fourth clamping plate 452, a third adjusting rod 453, and a fourth adjusting rod 454. The third clamping plate 451 is located on the side of the first flange 22 away from the second flange 32, and the fourth clamping plate 452 is located on the side of the second flange 32 away from the first flange 22. The third adjusting rod 453 and the fourth adjusting rod 454 are spaced apart and connected between the third clamping plate 451 and the fourth clamping plate 452. The first clamping plate 41 and the third clamping plate 451 are also spaced apart. The design of the third clamping plate 451, the fourth clamping plate 452, the third adjusting rod 453, and the fourth adjusting rod 454 not only enhances the stability of the structure but also improves the seismic performance of the equipment. That is, this not only ensures the force transmission effect but also achieves the anti-detachment function.

[0037] like Figures 1 to 5As shown, in this embodiment, the fixing structure 40 further includes a fifth adjusting rod 455 and a sixth adjusting rod 456. The fifth adjusting rod 455 is connected between the first clamping plate 41 and the third clamping plate 451, and the sixth adjusting rod 456 is connected between the second clamping plate 42 and the fourth clamping plate 452. By adding the additional fifth adjusting rod 455 and sixth adjusting rod 456, the tightness of the connection and the stability of the structure are further improved, making it suitable for power facilities under extreme weather conditions, such as wind power stations and solar power stations in high-altitude and cold regions, ensuring the safe operation of power facilities in harsh environments. Under extreme weather conditions, such as wind power stations and solar power stations in high-altitude and cold regions, the added fifth adjusting rod 455 and sixth adjusting rod 456 can effectively cope with harsh environmental factors such as sudden temperature changes and snow loads. The tight connection of the fifth adjusting rod 455 and sixth adjusting rod 456 improves the environmental adaptability and safety of the equipment.

[0038] like Figures 1 to 5 As shown, in this embodiment, both the first adjusting rod 43 and the second adjusting rod 44 are located between the fifth adjusting rod 455 and the sixth adjusting rod 456. This layout design makes the overall structure more compact and improves space utilization.

[0039] According to another aspect of this application, a transformer device is provided. This embodiment of the transformer device includes a gas relay mounting device, and the gas relay device is the aforementioned gas relay device. Applying the gas relay device of this embodiment to the transformer device can not only significantly improve the operational stability and safety of the transformer device, but also effectively cope with various complex operating conditions in the power system, such as load fluctuations and short-circuit faults, ensuring the normal operation of the power system. This plays an important role in guaranteeing power supply and improving the operating efficiency of power facilities.

[0040] Specifically, by adding a fixing structure 40, the gas relay device in this embodiment can effectively enhance the connection stability between the gas relay and the transformer device, and avoid loosening of the connection due to vibration or external force during operation, thereby improving the safety and reliability of the equipment operation.

[0041] Furthermore, the design with multiple adjusting rods makes installation and disassembly more convenient, reducing maintenance costs and improving work efficiency. Applying the gas relay device of this embodiment to transformer systems can significantly improve the operational stability and safety of the transformer system, playing a vital role in ensuring the normal operation of the power system.

[0042] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0043] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0044] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
