Description

Technical Field

[0001] This invention relates to the field of high-voltage equipment technology, and in particular to an internal optical fiber arrangement device for optical fiber insulators. Background Technology

[0002] Fiber optic insulators are composite insulators with embedded optical fibers. The outer insulator provides insulation, while the inner fiber conducts current. Optical current measuring devices utilize the Faraday magneto-optical effect to measure the current being measured. These devices mainly consist of three parts: a fiber optic current sensing loop, a fiber optic insulator, and a data acquisition unit. When used in current measuring devices, fiber optic insulators can experience faults such as discharge, ablation, and fiber damage. Analysis has revealed that these faults primarily originate from the disordered distribution of materials within the fiber optic insulator. Summary of the Invention

[0003] This invention addresses the problem of uncontrollable chaotic fiber distribution inside fiber optic insulators by proposing a fiber optic insulator internal fiber optic arrangement device. When the arrangement device moves within the insulator, each positioning slot provides guidance for each fiber, ensuring that each fiber is arranged axially as the device moves along the insulator, resulting in a more orderly fiber arrangement and preventing fiber entanglement within the insulator.

[0006] The above solution provides an internal fiber optic insulator arrangement device. In use, it is placed inside the insulator cavity, ensuring that multiple contact parts abut against the inner wall of the insulator, thereby defining the positions of multiple positioning slots within the insulator. Each fiber is respectively positioned within one of the positioning slots and passes through the main body of the arrangement device along the slots. Therefore, when the arrangement device slides along the insulator axis within the insulator, each fiber can be arranged along the insulator axis under the guidance of the positioning slots, resulting in a more orderly fiber arrangement and preventing fiber entanglement within the insulator.

[0007] In one embodiment, the plurality of abutting portions are arranged at uniform intervals along a first circumferential direction, and the plurality of positioning grooves are also arranged at uniform intervals along the first circumferential direction.

[0010] In one embodiment, each of the support legs is provided with a roller at one end suspended outside the arrangement ring, the roller being used to abut against the inner wall of the insulator and roll along the axial direction of the insulator.

[0011] In one embodiment, the outer circumferential surface of the roller is provided with a first groove, and the positioning groove includes the first groove.

[0012] In one embodiment, each of the support feet has a portion located in the space enclosed by the inner ring of the arrangement ring, and this portion of the support foot is provided with a second groove that extends through the support foot along the axial direction of the arrangement ring, and the positioning groove includes the second groove.

[0013] In one embodiment, the length of each of the support feet is adjustable.

[0014] In one embodiment, each of the support legs includes a tail segment and a head segment, the tail segment being connected between the arrangement ring and the head segment, and the overlap length of the connection between the tail segment and the head segment in the length direction of the support leg is adjustable, and the abutment portion belongs to the head segment.

[0015] In one embodiment, the tail section is provided with a row of protruding teeth arranged along the length direction of the support foot, and the head section is provided with a row of tooth grooves arranged along the length direction of the support foot, wherein the protruding teeth and the tooth grooves can mesh with each other.

[0016] In one embodiment, the plurality of support feet constitute a support assembly, and the main body of the arrangement device includes two support assemblies.

[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments of this application, an internal optical fiber arrangement device 10 for an optical fiber insulator is provided, including a main body of the arrangement device. The main body of the arrangement device has a plurality of abutment portions (not shown in the figure) for abutting against the inner wall of the insulator 20. The main body of the arrangement device is provided with a plurality of positioning grooves 13 for positioning optical fibers 30. The plurality of positioning grooves 13 are arranged at intervals, and each positioning groove 13 penetrates the arrangement device 10 along the axial direction of the insulator 20.

[0026] The above-described solution provides an internal fiber optic insulator fiber optic arrangement device 10. In use, it is placed inside the cavity of the insulator 20, ensuring that multiple contact parts abut against the inner wall of the insulator 20. This prevents the arrangement device 10 from shaking within the insulator 20, and maintains relatively stable positions for the multiple positioning slots 13. Each optical fiber 30 is respectively positioned within one of the positioning slots 13 and passes through the main body of the arrangement device along the slots 13. Therefore, when the arrangement device 10 moves along the axial direction of the insulator 20, each optical fiber 30 can be arranged along the axial direction of the insulator 20 under the guidance of the positioning slots 13, resulting in a more orderly arrangement of the optical fibers 30 and preventing entanglement of the optical fibers 30 within the insulator 20.

[0027] Specifically, the main body of the arrangement device can be actively driven to move along the axial direction of the insulator 20 within the insulator 20 by a drive device, or it can be moved along the axial direction of the insulator 20 within the insulator 20 by manual pulling, or the buoyancy of the filling medium 40 when filling the cavity of the insulator 20 with glue can be used to push the arrangement device 10 to move along the axial direction of the insulator 20.

[0028] like Figure 3 As shown, in some embodiments, the density of the main body of the arrangement device is less than 0.9 g / cm³. 3 The main body of the arrangement device has a lower density than the filling medium 40 used for potting. As the filling medium 40 is continuously poured into the insulator 20, the main body of the arrangement device will float in the filling medium 40 and be pushed forward by the filling medium 40. During the forward movement of the arrangement device 10, the optical fibers 30 guided by each positioning groove 13 are straightened and distributed along the axial direction of the insulator 20, and finally each optical fiber 30 is fixed in the insulator 20 by the filling medium 40.

[0029] Specifically, in one embodiment, the main body of the arrangement device is made of polypropylene.

[0030] Of course, alternatively, the main body of the arrangement device can also be made of other materials, as long as its density is less than 0.9 g / cm³. 3 It can slide along the axial direction of the insulator 20 under the action of the filling medium 40.

[0031] The arrangement of the multiple positioning slots 13 can be varied. For example, the multiple positioning slots 13 can be arranged circumferentially along the inner wall of the insulator 20, and the opening of each positioning slot 13 faces the inner wall of the insulator 20. Thus, each optical fiber 30 guided by the positioning slot 13 is arranged on the inner wall of the insulator 20, and each optical fiber 30 is arranged along the axial direction of the insulator 20. The multiple optical fibers 30 are distributed circumferentially along the inner wall of the insulator 20.

[0032] Alternatively, multiple positioning slots 13 are spaced apart in the inner cavity of the insulator 20, and the positioning slots 13 are spaced apart from the inner wall of the insulator 20. In this case, multiple optical fibers 30 guided by the positioning slots 13 will be spaced apart from the inner wall of the insulator 20, and the optical fibers 30 will be fixed in the insulator 20 under the action of the filling medium 40.

[0033] Or, as Figures 1 to 3 As shown, a portion of the positioning grooves 13 are arranged circumferentially along the inner wall of the insulator 20, and the openings of each positioning groove 13 in this portion face the inner wall of the insulator 20; another portion of the positioning grooves 13 are arranged at intervals in the inner cavity of the insulator, and the positioning grooves 13 in this portion are arranged at intervals with the inner wall of the insulator 20.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, in some embodiments, the plurality of abutting portions are arranged at uniform intervals along a first circumferential direction, and the plurality of positioning grooves 13 are also arranged at uniform intervals along the first circumferential direction. In other words, the plurality of abutting portions and the plurality of positioning grooves 13 are arranged along the same circumferential direction. Therefore, when the plurality of abutting portions abut against the inner wall of the insulator 20, the plurality of positioning grooves 13 are arranged at circumferential intervals defined by the axis of the insulator 20. Finally, the optical fibers 30, which are positioned and guided by each positioning groove 13, are arranged at intervals on the outer circumference of the axis of the insulator 20. Moreover, the optical fibers 30 positioned by the uniformly spaced plurality of positioning grooves 13 are also uniformly distributed, which can minimize the possibility of uneven distribution of optical fibers 30.

[0035] On the other hand, the inner cavity of the general insulator 20 is a cylindrical cavity, and the plurality of abutting parts are evenly spaced along the circumference of the insulator 20. When the arrangement device 10 is placed in the inner cavity of the insulator 20, each abutting part abuts against the inner wall of the insulator 20, and the position of the arrangement device 10 in the insulator 20 is more stable.

[0036] Furthermore, such as Figures 1 to 3 As shown, in order to make the main body of the arrangement device move more smoothly in the insulator 20, in some embodiments, a roller 1221 can be provided at the abutment part, so that the arrangement device 10 moves in the insulator 20 by rolling, thereby reducing the frictional resistance between the arrangement device 10 and the insulator 20.

[0037] Of course, in other embodiments, the surface of the contact portion can be processed to have a smaller roughness, so that the contact portion can directly contact and rub against the inner wall of the insulator 20, and the friction between the two is also smaller.

[0038] like Figure 1 and Figure 2As shown, in some embodiments, the main body of the arrangement device includes an arrangement ring 11 and a plurality of support feet 12. Each support foot 12 is connected to the arrangement ring 11, and one end of each support foot 12 is suspended outside the arrangement ring 11 to form the abutment portion. The plurality of support feet 12 are arranged at intervals along the circumference of the arrangement ring 11.

[0039] The positioning groove 13 can be formed on the arrangement ring 11, or on the support foot 12, or when the main body of the arrangement device also includes other structures, the positioning groove 13 can also be formed on the other structures described here.

[0040] The arrangement ring 11 confines the various support feet 12 together, stabilizing their relative positions. Each support foot 12 can abut against the inner wall of the insulator 20, allowing the arrangement device 10 to move stably within the insulator 20.

[0041] like Figure 1 and Figure 2 As shown, each of the abutting parts is located on a virtual circle, the diameter of which is larger than the outer diameter of the arrangement ring 11. When the abutting part abuts against the inner wall of the insulator 20, the arrangement ring 11 is spaced apart from the inner wall of the insulator 20.

[0042] Specifically in one embodiment, such as Figures 1 to 3 As shown, each of the supporting legs 12 is provided with a roller 1221 at one end suspended outside the arrangement ring 11. The roller 1221 is used to abut against the inner wall of the insulator 20 and roll along the axial direction of the insulator 20. Here, rolling along the axial direction of the insulator 20 means that the rotation axis of the roller 1221 is perpendicular to the axis of the insulator 20.

[0043] like Figure 3 As shown, during use, the cross-section of the arrangement ring 11 is parallel to the inner cavity of the insulator 20, the contact area between the filling medium 40 and the arrangement ring 11 is large, and the thrust provided mainly acts on the arrangement ring 11, so that the arrangement device 10 can move along the axial direction of the insulator 20.

[0044] Furthermore, such as Figures 1 to 3 As shown, in some embodiments, the outer circumferential surface of the roller 1221 is provided with a first groove 131, and the positioning groove 13 includes the first groove 131. Each first groove 131 can provide a guiding function for an optical fiber 30. While the roller 1221 abuts against the inner wall of the insulator 20 and rolls along the axial direction of the insulator 20, it combs the optical fiber 30 so that it is arranged along the axial direction of the insulator 20 and in contact with the inner wall of the insulator 20.

[0045] Furthermore, in other embodiments, such as Figure 1 and Figure 2 As shown, each of the support feet 12 has a portion located within the space enclosed by the inner ring of the arrangement ring 11. This portion of the support foot 12 is provided with a second groove 132, which penetrates the support foot 12 along the axial direction of the arrangement ring 11. The positioning groove 13 includes the second groove 132. The second groove 132 located within the space enclosed by the arrangement ring 11 can also be used to position the optical fiber 30.

[0046] When the arrangement device 10 in a certain embodiment includes both the first groove 131 and the second groove 132, its applicability is wider. It can be applied to situations such as... Figure 3 The arrangement shown is suitable for situations where the optical fiber 30 needs to be attached to the inner wall of the insulator 20, and also for situations where the optical fiber 30 is spaced apart from the inner wall of the insulator 20. Of course, in a certain application, the optical fiber 30 can also be arranged in both the first groove 131 and the second groove 132.

[0047] In some embodiments, the inner ring surface of the arrangement ring 11 may be further provided with a plurality of third grooves (not shown in the figure), each third groove passing through the arrangement ring 11 along the axial direction of the arrangement ring 11. The third groove also belongs to the positioning groove 13 and can be used to comb the optical fiber 30.

[0048] In some embodiments, the length of each of the support legs 12 is adjustable. In other words, by adjusting the length of the support legs 12, each abutment portion can abut against the inner wall of the insulator 20 with a different diameter, further expanding the applicability of the arrangement device 10.

[0049] The length adjustment method of the support foot 12 can be diverse. For example, the support foot 12 can be a telescopic component, so that its length can be adjusted by telescoping; or the support foot 12 can be divided into multiple support segments in the length direction, and some support segments can be selectively used as needed, so that the length of the support foot 12 can adapt to the inner wall diameter of the insulator 20.

[0050] It can also be like Figure 1 and Figure 2As shown, each of the support legs 12 includes a tail section 121 and a head section 122. The tail section 121 connects the arrangement ring 11 and the head section 122, and the abutting portion belongs to the head section 122. The overlap length of the connecting portion of the tail section 121 and the head section 122 in the length direction of the support leg 12 is adjustable. If a longer length of the support leg 12 is required to accommodate an insulator 20 with a larger inner diameter, the overlap length of the tail section 121 and the head section 122 can be reduced. The smaller the overlap length, the longer the support leg 12. If a shorter length of the support leg 12 is required to accommodate an insulator 20 with a smaller inner diameter, the overlap length of the tail section 121 and the head section 122 can be increased.

[0051] Specifically, such as Figure 2 As shown, the tail section 121 has a row of protruding teeth 1211 arranged along the length of the supporting leg 12, and the head section 122 has a row of tooth grooves arranged along the length of the supporting leg 12. The protruding teeth 1211 and the tooth grooves can mesh with each other. It can be understood that the protruding teeth 1211 and the tooth grooves in the overlapping part of the tail section 121 and the head section 122 mesh with each other, so that the relative position of the tail section 121 and the head section 122 is stable after the overlap length of the tail section 121 and the head section 122 is set. The longer the overlap length of the protruding teeth 1211 and the tooth grooves, the shorter the length of the supporting leg 12.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the roller 1221 is provided at one end of the head section 122 away from the tail section 121.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the portion of the support foot 12 that is suspended outside the arrangement ring 11 is tilted away from the end face of the arrangement ring 11 in a direction away from the arrangement ring 11.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments, multiple support feet 12 constitute a support assembly 14, and the main body of the arrangement device includes two support assemblies 14. The abutting portions of one support assembly 14 are all located on one side of the arrangement ring 11, and the abutting portions of the other support assembly 14 are located on the other side of the arrangement ring 11. The two sets of support assemblies 14 can be more stably supported in the insulator 20.

[0055] Furthermore, the support feet 12 included in the two support components 14 have a one-to-one correspondence. In other words, the two support components 14 are symmetrically arranged with the plane passing through the center of the arrangement ring 11 and perpendicular to the axis of the arrangement ring 11 as the plane of symmetry. When the first groove 131 on the roller 1221 is used to position the optical fiber 30, each optical fiber 30 is defined by two first grooves 131 arranged axially on the insulator 20, which further improves the smoothness of combing the optical fiber 30.

[0056] like Figure 3 As shown, when the insulator 20 is filled with adhesive, the support component 14 on the side of the arrangement ring 11 facing the filling medium 40 is immersed in the filling medium 40, while the other support component 14 is located outside the filling medium 40. The optical fiber 30 located between the two first grooves 131 is arranged along the axial direction of the insulator 20.

[0057] Moreover, since the support feet 12 included in the two support components 14 are tilted in opposite directions, the distance between the two first grooves 131 arranged axially in the insulator 20 is much greater than the thickness of the arrangement ring 11. Therefore, the length of the optical fiber segment between the two first grooves 131 is longer, which makes the optical fiber 30 arranged axially in the insulator 20 more accurate.
