Description

Technical Field

[0001] This application relates to the field of insulation testing, and in particular to an insulation rod withstand voltage test frame. Background Technology

[0002] Insulating rods are essential safety tools for the operation and maintenance of power systems. To verify the safety effectiveness of insulating rods, a withstand voltage test is required.

[0003] For example, the patent with publication number "CN219715515U" and title "An Insulating Rod Test Bracket with Automatic Adjustable Gap" discloses a test bracket for supporting an insulating rod, which is then used to clamp and fix the insulating rod to be tested through a main electrode clamp and an auxiliary electrode clamp.

[0004] However, while clamping makes installing the insulating rod very convenient, the fixed size of the through hole and clamping hole prevents the sidewalls of the hole from fitting the insulating rod well, and also makes it inconvenient to test insulating rods of different thicknesses, thus limiting its applicability. Summary of the Invention

[0005] To facilitate testing of insulating rods of different thicknesses, this application provides an insulating rod withstand voltage test frame.

[0006] The insulating rod withstand voltage test frame provided in this application adopts the following technical solution: An insulating rod withstand voltage test frame includes a placement frame and a plurality of conductive rods disposed on the placement frame, with cables connected to the ends of the conductive rods; each conductive rod is further provided with a support base for supporting the insulating rod, and each conductive rod is provided with a conductive wire capable of being wound around the insulating rod; each conductive rod is provided with a positioning seat, the positioning seat including a positioning block connected to the conductive rod and a connector spirally connected to the positioning block; the connector is used to fix the conductive wire to the positioning block.

[0007] By adopting the above technical solution, the placement frame is used to support the conductive rod, the cable can energize or ground the conductive rod, the support base can support the insulating rod on the conductive rod to reduce rolling, the conductive wire is wound around the insulating rod by winding, and then detachably fixed to the conductive rod by the positioning seat, the connector presses the conductive wire tightly on the positioning block to prevent the conductive wire from being too loose, and the winding method can facilitate the testing of insulating rods of different thicknesses, thereby improving the applicability of the test frame.

[0008] Optionally, the support base consists of multiple conductive sponges fixed to the conductive rod, with grooves formed between adjacent sponges for placing the insulating rod.

[0009] By adopting the above technical solution, the conductive sponge can support the insulating rod on the one hand, and on the other hand, placing the insulating rod on the groove can also provide a preliminary limiting effect, giving the insulating rod better stability. It also facilitates the winding of conductive wires around the insulating rod, and the winding method facilitates the transfer of current from the conductive wires to the insulating rod when energized.

[0010] Optionally, the conductive rod has a first sliding groove, and the positioning block is slidably disposed in the first sliding groove; the first sliding groove is also provided with a tensioning elastic element that can push the positioning block to slide along the length direction of the first sliding groove, and the conductive rod has a limiting groove communicating with the first sliding groove, and the limiting groove is provided with an elastic limiting element that can restrict the sliding of the positioning block.

[0011] By adopting the above technical solution, the first slide groove provides movement space for the positioning block. The tensioning elastic element can push the positioning block, forcing the conductive wire wound on the insulating rod to be tensioned, thus allowing the conductive wire to better contact the insulating rod. One end of the elastic limiting element can extend from the limiting groove into the first slide groove. When one end of the elastic limiting element extends into the first slide groove, the positioning block will be stuck by the elastic limiting element after moving along the first slide groove. At this time, the positioning block will not be pushed by the tensioning elastic element, and the conductive rope is in a slack state, which allows the insulating rod to be easily removed by pulling it out.

[0012] Optionally, the first chute is further fixedly provided with a guide rod, which passes through the positioning block and is fixed at both ends to the chute wall of the first chute. The axis of the guide rod is parallel to the length direction of the first chute.

[0013] By adopting the above technical solution, the guide rod is used to guide the movement of the positioning block, improve the stability of the positioning block movement, and enable the positioning block to slide stably in the first groove when moving.

[0014] Optionally, the positioning seat is a gripper capable of restricting the insulating rod from rolling on the conductive rod; the conductive rod is provided with a spreading assembly for spreading the gripper; the conductive rod has a second sliding groove, the gripper is slidably disposed in the second sliding groove, the conductive rod has a clearance groove communicating with the second sliding groove, a pushing elastic element is disposed in the clearance groove, the pushing elastic element can push the gripper to move towards the outlet direction of the second sliding groove, the gripper has a clamping end for gripping the insulating rod, the output end of the spreading assembly is connected to the clamping end of the gripper, and the conductive wire is embedded in the clamping end of the gripper; when the clamping end of the gripper moves away from the second sliding groove, the spreading assembly can cause the clamping end of the gripper and the conductive wire on the clamping end to spread out synchronously.

[0015] By adopting the above technical solution, the gripper's clamping end can clamp the insulating rod. When the insulating rod needs to be disassembled, the opening component can open the gripper. The pushing elastic element can push the gripper to slide in the second slide groove. Since the conductive wire is embedded in the clamping end and can also be wound around the insulating rod, when the insulating rod needs to be disassembled, pulling the insulating rod can also pull the gripper. At this time, the opening component can make the gripping end of the gripper and the conductive wire open simultaneously. The coil formed by the conductive wire wound around the insulating rod will be expanded, and the expanded coil can facilitate the removal of the insulating rod.

[0016] Optionally, the gripper also has a sliding end, which is slidably disposed in the second slide groove. One end of the sliding end extends out of the second slide groove and is fixedly connected to the clamping end. The clamping end includes multiple clamping plates, which are connected to each other by a torsion spring. The clamping plate closest to the sliding end is fixedly connected to the sliding end, and the clamping plate farthest from the sliding end is fixedly connected to the output end of the spreading assembly. The torsion spring can force the clamping end to tend to retract.

[0017] By adopting the above technical solution, the sliding end of the gripper can move within the second groove. When the insulating rod is placed in the gripper, the gripper moves downward, causing the sliding end to move into the second groove. At this time, the opening component is not working, and the clamping plate, under the action of the torsion spring, tends to clamp and retract the insulating rod. When the insulating rod is pulled, the output end of the opening component pulls the clamping plate furthest from the sliding end. At this time, the clamping plate is pulled open by the output end of the opening component, thereby opening the clamping end of the gripper, ultimately facilitating the removal of the insulating rod from the gripper.

[0018] Optionally, the spreading assembly includes a rotating rod rotatably disposed in the relief groove, and a pull rope fixedly connected to the rotating rod, one end of the pull rope being fixedly connected to the rotating rod, and the other end being fixedly connected to the clamping plate furthest from the sliding end.

[0019] By adopting the above technical solution, the rotating rod can wind the pull rope when it rotates, and it can also release the pull rope wound on the rotating rod. When it is necessary to open the gripper's clamping end, the rotating rod rotates to wind the pull rope, and the pull rope will pull the clamping end, causing the clamping end to open. When it is necessary to clamp the insulating rod, the rotating rod rotates to release the pull rope wound on the rotating rod. The pull rope becomes loose and can no longer pull the clamping end. At this time, the clamping plate can clamp the insulating rod under the action of the torsion spring.

[0020] Optionally, the sliding end has a toothed groove, and the rotating rod has protruding teeth that mesh with the toothed groove. When the sliding end slides toward the outlet direction of the second groove, it can drive the rotating rod to rotate, forcing the pull rope to wrap around the rotating rod.

[0021] By adopting the above technical solution, the sliding end can rotate the rotating rod through meshing. When the sliding end moves upward, it indicates that the insulating rod needs to be disassembled. At this time, the sliding end will drive the rotating rod to rotate in one direction, allowing the rotating rod to release the pull rope wrapped around it. Conversely, when the sliding end moves downward, it will drive the rotating rod to rotate in the other direction. At this time, the rotating rod will wrap around the pull rope, and the pull rope will be under tension, which can pull the gripping end of the gripper, allowing the gripping end and the conductive wire located at the gripping end to separate, thus facilitating the removal of the insulating rod.

[0022] Optionally, the conductive rod also has a linkage groove that communicates with the limiting groove and the second sliding groove respectively. A linkage block is slidably disposed in the linkage groove. The linkage block is fixedly connected to the elastic limiting member. A linkage elastic member is disposed in the linkage groove to force the linkage block to move toward the second sliding groove. The linkage block has a pushing part. The sliding end can push the pushing part to move the linkage block toward the limiting groove. The side wall of the limiting groove also has a first guide surface. The elastic limiting member has a second guide surface that abuts against the first guide surface.

[0023] By adopting the above technical solution, the linkage block can slide in the linkage groove. When the gripper moves downward to clamp the insulating rod, it can push the elastic limiting member. The first guide surface can guide the second guide surface of the elastic limiting member, allowing the second guide surface of the elastic limiting member to enter the limiting groove along the first guide surface, so that the elastic limiting member can no longer limit the positioning block. At this time, the positioning block will maintain tension on the conductive wire under the push of the tensioning elastic member. When the gripper moves upward, the linkage elastic member will push the linkage block to slide towards the second slide groove. The elastic limiting member will reset under its own elasticity, causing one end of the elastic limiting member to extend into the first slide groove. At this time, when the positioning block slides in the first slide groove, it can be limited by the elastic limiting member, so that the tensioning elastic member cannot push the positioning block, thereby making the conductive wire slack and facilitating the removal of the insulating rod by extraction.

[0024] Optionally, the placement rack is further provided with an abutment component, the abutment component including an abutment seat fixed to the placement rack and an abutment block slidably disposed on the abutment seat, the height of the abutment block being higher than the sliding end of the gripper.

[0025] By adopting the above technical solution, the abutment component is used to assist in the installation of the insulating rod. The abutment block prevents the insulating rod from pressing down on the gripper due to its own weight during installation. During installation, the end of the insulating rod is first supported on the abutment block. Then, the end of the insulating rod is passed through the coil formed by the conductive wire on the gripper one by one. After all the wires are passed through, the abutment block is removed, and the weight of the insulating rod is transferred to the gripper. The gripper moves downward and clamps the insulating rod.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a winding method, it is convenient to test insulating rods of different thicknesses, thereby improving the applicability of the test frame.

[0027] 2. The positioning seat can slide on the conductive rod, thereby relaxing the conductive wire and making it convenient for the insulating rod to be directly inserted into the coil formed by the conductive wire.

[0028] 3. The coil of the conductive wire is linked to the gripper. When the gripper is opened, the coil of the conductive wire will also enlarge, making it easy to remove the insulating rod by pulling it out. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0039] This application discloses an insulating rod withstand voltage test frame.

[0040] Example 1: Reference Figure 1 An insulating rod withstand voltage test frame includes a placement frame 2, multiple conductive rods 21, and two sets of cables 22. The multiple conductive rods 21 are installed parallel to each other and equidistantly on the placement frame 2. Each conductive rod 21 is arranged sequentially. Odd-numbered conductive rods 21 are connected by one set of cables 22, and even-numbered conductive rods 21 are connected by the other set of cables 22. The conductive rods 21 are also provided with support seats for supporting the insulating rods 1. In this embodiment, the support seats are several conductive sponges 24, specifically two, and a groove 241 for placing the insulating rods 1 is formed between the two conductive sponges 24. Each conductive rod 21 is provided with a conductive wire 23. In this embodiment, the conductive wire 23 is a copper wire. After the insulating rod 1 is placed on the groove 241, the conductive wire 23 is wound around the insulating rod 1. The two ends of the conductive wire 23 are in contact with the conductive rod 21 and are detachably fixed. The odd number of conductive rods 21 are energized through the cable 22, and the even number of conductive rods 21 are grounded through the cable 22. Then, an insulation withstand voltage test is performed according to the national standard GB13398-2008.

[0041] The implementation principle of Example 1 is as follows: After the conductive wire 23 is wrapped around the insulating rod 1, the two ends of the conductive wire 23 are fixed on the conductive rod 21, and then the experiment is carried out by energizing.

[0042] Example 2: Reference Figure 2 and 3The difference between this embodiment and Embodiment 1 is that the conductive rod 21 is provided with a positioning seat 4, which includes a positioning block 41 and a connector 42. The positioning block 41 is slidably connected to the conductive rod 21, and the connector 42 is a bolt that is screwed to the connector 42 of the positioning block 41. The connector 42 can fix one end of the conductive wire 23 to the positioning block 41. The conductive wire 23 is used to wind the insulating rod 1. In this embodiment, the conductive wire 23 is embedded in the support seat. The initial state of the conductive wire 23 forms a coil 231 that can be wound. The support seat can expand or shrink the coil 231. After the coil 231 expands, the insulating rod 1 passes through the coil 231 of the conductive wire 23. Then the support seat shrinks the coil 231. Then, when the positioning block 41 moves, the conductive wire 23 is in a taut state, allowing the conductive wire 23 to be better wound on the insulating rod 1.

[0043] Reference Figure 2 and 3 The conductive rod 21 has a first groove 43, and the positioning block 41 is slidably disposed in the first groove 43. The first groove 43 is also provided with a tensioning elastic element 44, which is a spring. The tensioning elastic element 44 can push the positioning block 41 to slide along the length direction of the first groove 43. When the conductive wire 23 is connected to the positioning block 41, the tensioning elastic element 44 can keep the conductive wire 23 in a taut state.

[0044] Reference Figure 4 and 5 To improve the stability of the positioning block 41 sliding on the first slide groove 43, a guide rod 46 is also fixedly installed in the first slide groove 43. The guide rod 46 passes through the positioning block 41, and both ends of the guide rod 46 are fixed to the groove wall of the first slide groove 43. The axis of the guide rod 46 is parallel to the length direction of the first slide groove 43, and can be used to guide the sliding of the positioning block 41.

[0045] Reference Figure 5 and 6 In this embodiment, the support base is a gripper 3, which has a sliding end 35 and a clamping end 34; the conductive rod 21 has a second sliding groove 31, the sliding end 35 is slidably disposed in the second sliding groove 31, and the clamping end 34 can clamp the insulating rod 1; one end of the sliding end 35 extends out of the second sliding groove 31, and the end of the sliding end 35 extending out of the second sliding groove 31 is fixedly connected to the clamping end 34.

[0046] Reference Figure 5 and 6 The conductive rod 21 has a relief groove 32, which is connected to the second sliding groove 31. The relief groove 32 is provided with a support component 5. The output end of the support component 5 is connected to the clamping end 34, which can control the opening of the clamping end 34. Part of the conductive wire 23 is embedded in the clamping end 34.

[0047] The spreading component 5 can spread open the clamping end 34 of the gripper 3; after the clamping end 34 is spread open, the coil 231 of the conductive wire 23 wound on the insulating rod 1 will be spread open, which can facilitate the disassembly and installation of the insulating rod 1.

[0048] In this application, there are two clamping ends 34. The two clamping ends 34 limit the insulating rod 1 by clamping. The clamping end 34 includes multiple clamping plates 341. The clamping plates 341 are connected to each other by torsion springs. The clamping plate 341 closest to the sliding end 35 is fixedly connected to the sliding end 35, and the clamping plate 341 farthest from the sliding end 35 is fixedly connected to the output end of the spreading assembly 5. The torsion springs can force the clamping ends 34 to tend to retract.

[0049] Reference Figure 5 and 6 A pushing elastic element 33 is provided inside the clearance groove 32. The sliding end 35 of the gripper 3 extends into the clearance groove 32. The pushing elastic element 33 is a spring. One end of the pushing elastic element 33 is fixedly connected to the sliding end 35 located in the clearance groove 32, and the other end is fixedly connected to the bottom of the clearance groove 32. The pushing elastic element 33 can push the gripper 3 to move towards the outlet direction of the second slide groove 31. When the gripping end 34 of the gripper 3 moves away from the second slide groove 31, the spreading component 5 enables the gripping end 34 of the gripper 3 and the conductive wire 23 on the gripping end 34 to spread out synchronously.

[0050] Reference Figure 5 and 6 The spreading assembly 5 includes a rotating rod 51 and a pull rope 52. The rotating rod 51 is located in the relief groove 32 and its two ends are rotatably set on the side wall of the relief groove 32. The rotating rod 51 is positioned higher than the sliding end 35 extending into the relief groove 32. One end of the rope is fixedly connected to the rotating rod 51, and the other end is fixedly connected to the clamping plate 341 furthest from the sliding end 35.

[0051] Reference Figure 5 and 6 The sliding end 35 has a toothed groove, and the rotating rod 51 has a toothed protrusion that meshes with the toothed groove. When the sliding end 35 slides toward the outlet direction of the second groove 31, it can drive the rotating rod 51 to rotate, forcing the pull rope 52 to wrap around the rotating rod 51. The toothed groove and the toothed protrusion are not shown in this embodiment.

[0052] Reference Figure 5 and 6When the gripper 3 moves away from the second slide groove 31, the rotating rod 51 can retract the wire, and the pull rope 52 can pull the clamping plate 341, allowing the clamping end 34 to unfold. After the clamping end 34 unfolds, the coil 231 of the conductive wire 23 is also stretched open, making it easier to pull out the insulating rod 1. Conversely, when the insulating rod 1 is installed on the gripper 3, the gripper 3 is pressed and moved towards the second slide groove 31. At this time, the pull rope 52 is released, and the clamping plate 341 clamps the insulating rod 1 under the action of the torsion spring.

[0053] Reference Figure 5 and 6 The conductive rod 21 has a limiting groove 47 and a linkage groove 211. The limiting groove 47 is connected to the first sliding groove 43. One end of the linkage groove 211 is connected to the limiting groove 47, and the other end of the linkage groove 211 is connected to the second sliding groove 31. An elastic limiting member 45 is provided in the limiting groove 47, and a linkage block 212 is provided in the linkage groove 211. The linkage block 212 is fixedly connected to the elastic limiting member 45. The elastic limiting member 45 is an elastic sheet. The side wall of the limiting groove 47 also has a first guide surface 48. The elastic limiting member 45 has a second guide surface 49 that abuts against the first guide surface 48. One end of the elastic limiting member 45 can extend from the limiting groove 47 into the first sliding groove 43. When the positioning block 41 slides to one side of the elastic limiting member 45, the elastic limiting member 45 can restrict the movement of the positioning block 41.

[0054] Reference Figure 5 and 6 The linkage groove 211 is provided with a linkage elastic member 213 that forces the linkage block 212 to move toward the second slide groove 31. The linkage block 212 has a pushing part 214. The sliding end 35 of the gripper 3 can push the pushing part 214 to move the linkage block 212 toward the limiting groove 47. At this time, the second guide surface 49 of the elastic limiting member 45 abuts against the first guide surface 48, and under the guidance of the first guide surface 48, one end of the elastic limiting member 45 extends into the first slide groove 43.

[0055] Reference Figure 7 The placement frame 2 is also equipped with an abutment component 6, which includes an abutment seat 61 and an abutment block 62. The abutment seat 61 is fixed to the placement frame 2, and the abutment block 62 is slidably disposed on the abutment seat 61. The height of the abutment block 62 is higher than the height of the gripper 3. During the installation of the insulating rod 1, the insulating rod 1 is first supported by the abutment block 62 so that the insulating rod 1 will not directly press the gripper 3 due to its weight. After the insulating rod 1 is passed through the coil 231 of the conductive wire 23, the abutment block 62 is removed, allowing the insulating rod 1 to press the gripper 3. This enables the gripper 3 to clamp the insulating rod 1.

[0056] The implementation principle of Example 2 is as follows: During installation, first support the insulating rod 1 on the abutment block 62, then let the insulating rod 1 pass through the coil 231 formed by the conductive wire 23 on the clamping end 34 of the gripper 3. After the insulating rod 1 has passed through the coil 231, remove the insulating rod 1. The weight of the insulating rod 1 will press the gripper 3 downward. During the downward movement of the gripper 3, the pull rope 52 will be relaxed, and the torsion spring between the clamping plates 341 will clamp the clamping plates 341 on the insulating rod 1, so that the clamping end 34 of the gripper 3 clamps the insulating rod 1. The conductive wire 23 embedded on the clamping end 34 will also come into contact with the insulating rod 1. The downward movement of the sliding end 35 of the gripper 3 can push the pushing part 214 of the linkage block 212, so that the linkage block 212 slides towards the first sliding groove 43. The linkage block 212 will push the elastic limiting member 45. Under the guidance of the first guiding surface 48, the second guide surface 49 of the elastic limiting member 45 enters the limiting groove 47. At this time, the elastic limiting member 45 no longer limits the positioning block 41. The positioning block 41 moves under the action of the tensioning elastic member 44, so that the conductive wire 23 is in a taut state, and the conductive wire 23 is more closely wound around the insulating rod 1.

[0057] When disassembling the insulating rod 1 after the test, grasp the insulating rod 1 with both hands and move it upwards. At this time, the gripper 3 will also move upwards, and the pull rope 52 will pull the clamping end 34 of the gripper 3, thereby opening the gripper 3. The linkage elastic element 213 in the linkage groove 211 will push the linkage rod to move towards the second slide groove 31, and the elastic limiting element 45 will reset, so that one end of the elastic limiting element 45 extends into the first slide groove 43. When the insulating rod 1 moves upwards, the conductive wire 23 will be further stretched. At this time, the conductive wire 23 will pull the positioning block 41, so that the positioning block 41 is limited by the elastic limiting element 45, so that the positioning block 41 is not driven by the tensioning elastic element 44. Then, let the insulating rod 1 move slightly downwards, the conductive wire 23 is in a relaxed state, and then pull the insulating rod 1 out in the axial direction to disassemble the insulating rod 1. When a new insulating rod 1 needs to be installed, the above installation method is repeated.
