Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a device for installing fiber optic temperature sensors on the contact arms of a vacuum circuit breaker. Background Technology

[0002] A vacuum circuit breaker is a high-voltage switching device that uses a vacuum medium to break and close circuits. Its contact arm, as the core conductive component, undertakes the functions of current transmission and mechanical linkage. Because the contact arm is prone to overheating and oxidation due to carrying large currents for a long time, it is necessary to monitor parameters such as contact arm temperature and contact resistance online.

[0003] To address safety requirements in energized areas, existing technologies often employ wired monitoring methods such as fiber optic temperature measurement, which necessitates the installation of sensors or cables on the contact arm surface. However, due to variations in circuit breaker models, contact arm sizes differ, requiring traditional fixing devices to be compatible with specific specifications, resulting in poor device adaptability. Furthermore, various sizes of clamps are typically pre-installed between the device and the contact arm, leading to difficult installation, complex wiring, and low maintenance efficiency.

[0042] In the description of this utility model, it should be noted that the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Combination Figures 1 to 6 This utility model provides a device for installing an optical fiber temperature sensor on the contact arm of a vacuum circuit breaker, including a fixing component 1 and an adjusting component 2. The fixing component 1 is sleeved on the contact arm of the circuit breaker, and the adjusting component 2 is connected to the inner side of the fixing component 1 and abuts against the contact arm. The fixing component 1 includes a first fixing plate 11 and a second fixing plate 12. One end of the first fixing plate 11 is provided with a first connecting part 111, and the other end of the first fixing plate 11 is provided with a second connecting part 112. One end of the second fixing plate 12 is provided with a third connecting part 121, and the other end of the second fixing plate 12 is provided with a fourth connecting part 122. The first connecting part 111 and the third connecting part 121 are detachably connected, and the second connecting part 112 and the fourth connecting part 122 are detachably connected. A first through hole 1a is formed between the first connecting part 111 and the third connecting part 121, and a second through hole 1b is formed between the second connecting part 112 and the fourth connecting part 122.

[0044] Specifically, the fixing component 1 consists of a first fixing plate 11 and a second fixing plate 12, and is detachably connected to the first connecting part 111 and the third connecting part 121, and the second connecting part 112 and the fourth connecting part 122, so as to connect the first fixing plate 11 and the second fixing plate 12 to form a ring structure sleeved on the outside of the contact arm, providing a mounting carrier for the fiber optic temperature sensor or cable, and installing the laying device on the contact arm by cooperating with the adjusting component 2; the adjusting component 2 is connected to the inside of the fixing component 1 and abuts against the contact arm, so that the fixing component 1 can be adapted to contact arms of different diameters by adjusting the adjusting component 2; the through hole includes a first through hole 1a formed between the first connecting part 111 and the third connecting part 121, and a second through hole 1b formed between the second connecting part 112 and the fourth connecting part 122, for passing through the fiber optic or cable, so that the fiber optic temperature sensor cable can be fixed on the contact arm by the device.

[0045] It should be noted that the inner connection between the adjusting component 2 and the fixing component 1 specifically refers to the side of the fixing component 1 that is close to the contact arm, such as... Figure 1In this configuration, the contact arm is located within a circular hole formed by the first fixing plate 11 and the second fixing plate 12 (the structure of the contact arm is not shown in the figure). The adjusting component 2 is disposed inside the circular hole, thereby making the diameter of the circular hole of the fixing component 1 adjustable, allowing the placement device to accommodate contact arms of different diameters. The specific shape of the fixing component 1 is not limited here; its outer ring structure can be as follows... Figure 1 The circle shown can also be a polygonal structure, as long as it can adapt to the installation conditions in the circuit breaker. The specific structure of the inner ring of the fixing component 1 is also not limited; it can be... Figure 1 The circle shown is adapted to the specific structure of the contact arm. When the contact arm has other structures, such as an ellipse or a polygon, the inner ring of the fixing component 1 is also set to a corresponding structure. At this time, the shape of the adjusting component 2 corresponds to the shape of the inner ring of the fixing component 1, and the adjusting component 2 is set inside the inner ring of the fixing component 1 so that the adjusting component 2 abuts against the contact arm.

[0046] With this configuration, the fiber optic temperature sensor installation device is divided into a fixing component 1 and an adjusting component 2. The adjusting component 2 allows for adjustable installation space of the fixing component 1, enabling flexible adjustment based on the contact arm size when the fixing component 1 is fitted onto the circuit breaker's contact arm. This allows the installation device to adapt to contact arms of different sizes and circuit breaker models, improving its versatility. The fixing component 1 consists of a first fixing plate 11 and a second fixing plate 12. A first connecting part 111, a second connecting part 112, a third connecting part 121, and a fourth connecting part 122 are respectively attached to both ends of the first fixing plate 11 and the second fixing plate 12, allowing for detachable connection between the fixing plate 11 and the contact arm. This simplifies the connection method and improves installation and maintenance efficiency. Furthermore, the detachable design allows for the recycling and reuse of the contact arm or installation device, saving costs. A through hole is provided at the connection between the first fixing plate 11 and the second fixing plate 12. The optical cable and other wire bundles of the optical fiber temperature sensor are stored through the first through hole 1a and the second through hole 1b, which further simplifies the structure of the optical fiber temperature sensor deployment device, avoids damage to the optical cable, and improves the overall service life.

[0047] It should be noted that the specific method of detachable connection between the first connecting part 111 and the third connecting part 121, and between the second connecting part 112 and the fourth connecting part 122 is not limited here. The detachable connection can be achieved through bolt connection, snap-fit, or a snap-fit ​​structure at the connection point. In a preferred embodiment, the first connecting part 111 and the third connecting part 121, and the second connecting part 112 and the fourth connecting part 122, are detachably connected by snap-fit. When installing the first fixing plate 11 and the second fixing plate 12, the connecting parts on the first fixing plate 11 and the second fixing plate 12 are simply snapped together.

[0048] In a preferred embodiment, a first disassembly hole 1c is formed between the first connecting portion 111 and the third connecting portion 121, and a second disassembly hole 1d is formed between the second connecting portion 112 and the fourth connecting portion 122. Specifically, the first disassembly hole 1c and the second disassembly hole 1d are used to enable quick disassembly of the first fixing plate 11 and the second fixing plate 12. When the installation device requires disassembly, a flat tool (such as a flathead screwdriver) can be inserted into the disassembly hole to pry open the snap-fit ​​connection portion, thereby achieving quick disassembly.

[0049] This design allows for the quick separation of the first fixing plate 11 and the second fixing plate 12 by inserting a disassembly tool (such as a flathead screwdriver) into the disassembly hole to pry open the snap-fit ​​structure. This solves the problem of traditional threaded connections requiring multiple screw tightenings and involving a large workload, simplifying the disassembly process, improving maintenance efficiency, and eliminating the need for specialized tools, thus reducing reliance on tools in on-site operations. The disassembly hole makes the assembly and disassembly of the fixing component 1 more convenient, avoiding disassembly difficulties caused by rusted or worn threads. It also reduces damage to the installation device and contact arm during assembly and disassembly, improves the maintainability of the installation device, facilitates equipment maintenance and reuse, and lowers operating costs.

[0050] The specific locations of the first disassembly hole 1c and the second disassembly hole 1d are not limited here. The entire disassembly hole can be located on one of the connecting parts, for example, the first disassembly hole 1c is formed on the first connecting part 111, and the third connecting part 121 has a planar structure at the corresponding position. Alternatively, they can be formed together on two corresponding connecting parts, for example, a part of the first disassembly hole 1c is formed on the first connecting part 111, and another part of the first disassembly hole 1c is formed on the third connecting part 121. When the first connecting part 111 and the third connecting part 121 are engaged, they together form the first disassembly hole 1c. The second disassembly hole 1d is the same as the first disassembly hole 1c, and will not be described in detail here.

[0051] In a preferred embodiment, a plurality of first through holes 1a are formed between the first connecting portion 111 and the third connecting portion 121, and the plurality of through holes are symmetrically arranged on both sides of the first disassembly hole 1c. Similarly, a plurality of second through holes 1b are formed between the second connecting portion 112 and the fourth connecting portion 122, and the plurality of second through holes 1b are symmetrically arranged on both sides of the second disassembly hole 1d. Specifically, the number of first through holes 1a and second through holes 1b is an even number, such as 2, 4, or 6. Figure 1 For example, two first through holes 1a and two second through holes 1b are set. The two first through holes 1a are symmetrically distributed on the left and right sides of the first disassembly hole 1c, and the two second through holes 1b are symmetrically distributed on the left and right sides of the second disassembly hole 1d. Here, left and right are... Figure 1 The directions shown are described, but the structure is not limited.

[0052] This symmetrical arrangement allows the fiber optic temperature sensor's cable and other wiring to be threaded through multiple holes, meeting the needs of simultaneous multi-cable deployment. It solves the problem of traditional devices having a fixed number of through holes and being unable to adapt to multi-sensor monitoring, thus improving the applicability and flexibility of the deployment device. The symmetrical arrangement of the through holes ensures even stress distribution on the cables after installation, avoiding instability or cable pulling caused by unilateral stress. This enhances the stability of the cable deployment, reduces the impact of loose or damaged cables on monitoring performance, and improves the overall reliability and lifespan of the equipment.

[0053] It should be noted that the specific implementation of the engagement between the first connecting part 111 and the third connecting part 121, and the second connecting part 112 and the third connecting part 121, is not limited here. It can be an elastic snap, a threaded bolt connection, or a groove-protrusion engagement connection, etc. In a preferred embodiment, the first connecting part 111 has a first connecting groove 111a, the third connecting part 121 has a first connecting protrusion 121a, and the first connecting groove 111a engages with the first connecting protrusion 121a; the second connecting part 112 has a second connecting groove 112a, and the fourth connecting part 122 has a second connecting protrusion 122a, and the second connecting groove 112a engages with the second connecting protrusion 122a. Specifically, the first connecting groove 111a of the first connecting part 111 engages with the first connecting protrusion 121a of the third connecting part 121, and the second connecting groove 112a of the second connecting part 112 engages with the second connecting protrusion 122a of the fourth connecting part 122. The snap-fit ​​structure achieves quick positioning and fixation by inserting protrusions into the grooves, eliminating the need for threaded tightening.

[0054] With this configuration, the first connecting part 111 and the third connecting part 121 are engaged through the first connecting groove 111a and the first connecting protrusion 121a, and the second connecting part 112 and the fourth connecting part 122 are engaged through the second connecting groove 112a and the second connecting protrusion 122a. This engagement structure eliminates the need for threaded tightening; simply aligning the protrusion with the groove and pressing it down completes the connection. This solves the problems of time-consuming installation and cumbersome operation associated with traditional threaded connections. It also addresses the issues of poor connection stability and loosening inherent in variable elastic snap-fit ​​structures, enabling rapid installation and disassembly of the fixing component 1 and significantly improving on-site work efficiency. The snap-fit ​​structure achieves fixation through mechanical interlocking, providing excellent anti-loosening performance. It can resist vibrations during circuit breaker operation, preventing connection loosening caused by vibration, ensuring connection stability between the installation device and the contact arm, reducing maintenance requirements during equipment operation, and improving equipment reliability.

[0055] In a preferred embodiment, the first connecting portion 111 has a third connecting protrusion 111b, and the third connecting portion 121 has a third connecting groove 121b, with the third connecting protrusion 111b engaging with the third connecting groove 121b. The second connecting portion 112 has a fourth connecting protrusion 112b, and the fourth connecting portion 122 has a fourth connecting groove 122b, with the fourth connecting protrusion 112b engaging with the fourth connecting groove 122b. Specifically, the third connecting protrusion 111b of the first connecting portion 111 and the third connecting groove 121b of the third connecting portion 121, and the fourth connecting protrusion 112b of the second connecting portion 112 and the fourth connecting groove 122b of the fourth connecting portion 122, form another set of engagements. This double engagement enhances the connection strength of the fixing assembly 1 and prevents unilateral engagement failure.

[0056] This design incorporates a double-clamping structure between the first connecting part 111 and the third connecting part 121, and between the second connecting part 112 and the fourth connecting part 122. The cooperation of these two sets of clamping structures creates a more stable connection, resolving the issue of potential loosening under long-term vibration with a single clamping structure. This significantly enhances the connection strength and reliability of the fixing component 1. The double-clamping structure restricts the fixing plate in both the radial and circumferential directions, improving the device's adaptability to high-frequency operation scenarios of circuit breakers, reducing the risk of device loosening due to vibration, ensuring the stable deployment of the fiber optic temperature sensor, and guaranteeing the accuracy and reliability of the monitoring data.

[0057] It should be noted that the specific structure of each connecting groove and connecting protrusion is not limited here, nor is their arrangement on the corresponding connecting part limited, as long as the connection of the first fixing plate 11 and the second fixing plate 12 can be achieved. In a preferred embodiment, the first connecting groove 111a, the second connecting groove 112a, the third connecting groove 121b, and the fourth connecting groove 122b have the same structure, and the first connecting protrusion 121a, the second connecting protrusion 122a, the third connecting protrusion 111b, and the fourth connecting protrusion 112b have the same structure. The first connecting groove 111a and the third connecting groove 121b are symmetrically arranged with respect to the center of the first disassembly hole 1c, and the second connecting groove 112a and the fourth connecting groove 122b are symmetrically arranged with respect to the center of the second disassembly hole 1d. Specifically, all connecting grooves have the same structure and size, and the corresponding connecting protrusions also have the same structure and size. Furthermore, as... Figure 1 and Figure 2 As shown, after the first fixing plate 11 and the second fixing plate 12 are connected, the first connecting groove 111a and the third connecting groove 121b are symmetrically arranged with respect to the center of the second disassembly hole 1d. That is, after the first connecting groove 111a engages with the first connecting protrusion 121a and the third connecting groove 121b engages with the third connecting protrusion 111b, the clamping force between the first connecting part 111 and the third connecting part 121 is symmetrically distributed with respect to the first disassembly hole 1d.

[0058] With this configuration, all connecting grooves and protrusions have identical structures and are symmetrically arranged relative to the center of the disassembly holes. This symmetrical and uniform structural design allows all components to share a common mold for production, solving the problem of high costs associated with custom-made molds for asymmetrical structures. This reduces production costs and improves production efficiency and processing accuracy. Furthermore, after the installation of the mounting device, the stress at the connections is uniform during operation, improving the stability of the mounting device.

[0059] In a preferred embodiment, the first connecting portion 111 has a first groove 111c, and the third connecting portion 121 has a second groove 121c. The first groove 111c and the second groove 121c are symmetrically arranged, forming a first disassembly hole 1c. The second connecting portion 112 has a third groove 112c, and the fourth connecting portion 122 has a fourth groove 122c. The third groove 112c and the fourth groove 122c are symmetrically arranged, forming a second disassembly hole 1d. Specifically, the first groove 111c of the first connecting portion 111 and the second groove 121c of the third connecting portion 121 combine to form the first disassembly hole 1c, and the third groove 112c of the second connecting portion 112 and the fourth groove 122c of the fourth connecting portion 122 combine to form the second disassembly hole 1d. Each groove has the same depth, ensuring that the tool can be precisely inserted at the locking point during disassembly, avoiding uneven force distribution caused by the asymmetrical structure, which could affect the disassembly effect or even damage the structure.

[0060] With this configuration, the first disassembly hole 1c is formed by combining the first groove 111c of the first connecting part 111 and the second groove 121c of the third connecting part 121, and the second disassembly hole 1d is formed by combining the third groove 112c and the fourth groove 122c. This groove combination structure design ensures that the disassembly tool can be accurately inserted and act on the snap-fit ​​interface, solving the problem of difficulty in applying force due to inaccurate disassembly hole position, making the disassembly process smoother and more efficient. In addition, by setting the grooves as symmetrical structures, the structures of the first connecting part 111 and the fourth connecting part 122 are the same, and the structures of the second connecting part 112 and the third connecting part 121 are the same. During the processing, the processing and forming of each connecting part can be achieved using two different mold structures, saving processing costs and improving processing efficiency.

[0061] It should be noted that the specific connection positions of the first fixing plate 11 and the second fixing plate 12 are not limited here, taking the fixing component 1 as an example. Figure 1 and Figure 2Taking the circular ring as an example, the connecting portions at both ends can be located on the same diameter; or they can be staggered, meaning the positions of the first connecting portion 111 and the third connecting portion 121 are staggered from the positions of the second connecting portion 112 and the fourth connecting portion 122, but are on the same diameter. In a preferred embodiment, the first fixing plate 11 and the second fixing plate 12 have the same structure, and further, the connecting positions of the first fixing plate 11 and the second fixing plate 12 are on the same diameter. Specifically, as shown... Figure 1 and Figure 2 As shown, the two fixing plates have the same structure. After the fixing component 1 is assembled, the first fixing plate 11 and the second fixing plate 12 are symmetrically arranged with respect to the center of the straight line where the first disassembly hole 1c and the second disassembly hole 1d are located. That is, after the first fixing plate 11 is rotated 180 degrees along the line connecting the centers of the two disassembly holes, it coincides with the second fixing plate 12.

[0062] With this configuration, the first fixing plate 11 and the second fixing plate 12 are structurally identical and interchangeable. This solves the problem of inconsistent left and right plate structures and easy reverse installation in traditional devices. Operators no longer need to identify the plate orientation; they can directly assemble them, simplifying the installation process, improving installation efficiency, and reducing the installation error rate. The identical fixing plates facilitate mass production and inventory management, reducing inventory types, lowering warehousing costs and production management complexity. They also facilitate spare parts replacement and maintenance, improving the convenience of equipment maintenance.

[0063] It should be noted that the specific structure of the adjusting component 2 is not limited here, as long as it can be adapted to the inner side of the fixing component 1, so that the fixing component 1 can adapt to touch arms of different sizes. In a preferred embodiment, the fixing component 1 is a ring structure, and the adjusting component 2 includes a plurality of first adjusting members 21 and a plurality of second adjusting members 22. The plurality of first adjusting members 21 and the plurality of second adjusting members 22 correspond one-to-one. The plurality of first adjusting members 21 are arranged radially overlapping inside the first fixing plate 11, and the plurality of second adjusting members 22 are arranged radially overlapping inside the second fixing plate 12.

[0064] Specifically, in combination Figures 1 to 6Multiple first adjusting members 21 are disposed inside the first fixed plate 11, that is, sequentially overlapped between the first fixed plate 11 and the contact arm. The specific number of first adjusting members 21 is not limited here; it is determined according to the adjustment space required by the device. Taking the structure with two first adjusting members 21 shown in the figure as an example, the two first adjusting members 21 are connected to each other. The inner first adjusting member 21 abuts against the contact arm (the structure of the contact arm is not shown in the figure), and the outer first adjusting member 21 is connected to the inner side of the first fixed plate 11. The second adjusting member 22 is disposed in the same way as the first adjusting member 21, and will not be described again here. In a preferred embodiment, the structure of the first adjusting member 21 and the second adjusting member 22 at the connection part corresponds to the structure of the connection part, that is, the adjusting member also has the same groove, protrusion, and through hole for wiring as the connection part, to meet the installation and wiring requirements of the fiber optic temperature sensor.

[0065] With this configuration, the fixing component 1 is a circular structure with a circular inner ring, facilitating a close fit to the contact arm during installation. This structural design allows the deployment device to adapt to different installation spaces, solving the problems of fixed shape and poor spatial adaptability of traditional devices, and improving the application range and flexibility of the device. The adjustment component 2 includes multiple first adjustment members 21 and second adjustment members 22 arranged radially overlapping inside the first fixing plate 11 and the second fixing plate 12. During the installation of the deployment device, by installing and removing adjustment members with different numbers of adjustment rings according to the specific dimensions of the contact arm, the inner rings of the fixing component 1 can be adjusted to fit the diameter of the contact arm. This solves the problems of fixed inner diameter and the need for pre-installation of multiple specifications in traditional devices, improving the versatility and on-site adaptability of the deployment device, and reducing equipment configuration costs.

[0066] It should be noted that the connection relationship between the adjusting component 2 and the fixing component 1 is not limited here. In optional cases, such as... Figure 2 As shown, there is a gap between the adjusting component 2 and the fixing component 1, and they are connected by a narrower connecting structure, such as a connecting rib, or the adjusting component 2 and the fixing component 1 are integrally formed. The various adjusting parts in the adjusting component 2 are also connected by connecting ribs or integrally formed in the same way. During the process of adapting the laying device to the contact arm, the excess adjusting parts of the inner ring are cut off so that the laying device can be adapted to the diameter of the contact arm.

[0067] In another alternative configuration, the adjusting component 2 is detachably connected to the fixing component 1, adjacent first adjusting components 21 are detachably connected, and adjacent second adjusting components 22 are detachably connected. For example, a connecting strip is provided on the outer side of the adjusting component (the side closer to the fixing component 1), and connecting holes are provided on the inner side of the fixing component 1 and the inner side of the adjusting component (the side closer to the contact arm). Multiple adjusting components are arranged in an overlapping manner and are detachably connected sequentially through the connecting strip and connecting holes. During use, the inner adjusting components are installed or removed according to the actual size of the contact arm to ensure that the mounting device matches the diameter of the contact arm.

[0068] With this configuration, the adjusting component 2 is detachably connected to the fixed component 1 and adjacent adjusting parts. By directly removing or installing the inner adjusting key, the inner diameter of the fixed component 1 can be changed, enabling rapid and precise adjustment of its inner diameter. This results in a higher compatibility between the installation device and the contact arm, improving the efficiency and convenience of on-site installation. The detachable adjusting component 2 design allows the device to be flexibly adjusted according to the actual size of the contact arm, ensuring a tight fit between the fixed component 1 and the contact arm. This avoids loosening of the device or monitoring errors due to excessive gaps, improving the accuracy and reliability of temperature monitoring, and extending the device's service life.
