Description

Technical Field

[0001] This application relates to the field of power equipment technology, and more specifically, to a fixed structure for a solid-sealed pole insulating tie rod. Background Technology

[0002] Solid-sealed poles are poles formed by embedding the conductive parts of a circuit breaker into a solid insulating material such as epoxy resin or thermoplastic material that is easy to cure. As a core component of a circuit breaker, the quality and stability of solid-sealed poles directly determine whether the circuit breaker can operate normally.

[0003] The solidified electrode post mainly consists of an electrode post housing, an arc-extinguishing chamber, a flexible connector, and an insulating tie rod. The electrode post housing includes an upper and lower lead-out socket. The upper and lower lead-out sockets, as well as the arc-extinguishing chamber, are solidified using an epoxy resin mixture, which offers high stability. After the product is cast, the flexible connector and insulating tie rod are assembled.

[0004] The insulating tie rod is installed onto the moving end of the arc-extinguishing chamber. Because the insulating tie rod is relatively heavy, it cannot remain centered after installation. During transportation, shaking can cause deformation at the connection between the insulating tie rod and the moving end of the arc-extinguishing chamber, affecting the performance of the pole.

[0005] In conclusion, how to stably reinforce the insulating tie rod during transportation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] The core of this application is to provide a fixed structure for a solid-sealed pole insulating tie rod.

[0028] Please refer to Figure 1 and 2 .

[0029] The fixed structure for the insulating tie rod of the fixed terminal post provided in this application includes a temporary stabilizing frame 2, which is located at the bottom of the terminal post housing 1, and the insulating tie rod 11 extends from the center of the bottom of the terminal post housing 1. During the transportation of the terminal post housing 1, the temporary stabilizing frame 2 can be detachably connected to both the bottom end of the terminal post housing 1 and the end of the insulating tie rod 11. In the connected state, the terminal post housing 1 and the temporary stabilizing frame 2 are relatively fixed, and the end of the insulating tie rod 11 is also relatively fixed to the temporary stabilizing frame 2, that is, the insulating tie rod 11 and the terminal post housing 1 also maintain a relatively fixed relationship.

[0030] The aforementioned fixed structure for the insulating tie rod of the fixed pole effectively solves the problem of deformation of the insulating tie rod 11 due to instability at the end of the insulating tie rod 11 during transportation.

[0031] The solidified pole insulating tie rod fixing structure provided in this application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0032] In one specific implementation, reference is made to... Figure 1 and 2 .

[0033] Specifically, the temporary stabilizer 2 includes a fixed long beam 21, which is a rod-shaped structure. The connection point between the insulating tie rod 11 and the temporary stabilizer 2 is located in the middle of the fixed long beam 21. The temporary stabilizer 2 has two connection points with the pole housing 1, located at both ends of the fixed long beam 21 along its length. With this structural arrangement, the portion between the two connection points of the fixed long beam 21 and the pole housing 1 has higher stability relative to the pole housing 1 and is less prone to swaying deformation; that is, the relative stability between the insulating tie rod 11 and the pole housing 1 is also relatively high.

[0034] Based on the above embodiments, refer to Figure 1 and 2 .

[0035] Specifically, with the temporary stabilizer 2 and the pole housing 1 relatively fixed, the end faces of the fixed long beam 21 and the pole housing 1 abut against each other; a mating groove 23 is provided on the side of the fixed long beam 21 facing the insulating tie rod 11, and the mating groove 23 is for the end of the insulating tie rod 11 to be inserted; the design depth of the mating groove 23 is greater than or equal to the protrusion distance of the insulating tie rod 11 relative to the bottom end face of the pole housing 1. The space inside the mating groove 23 is used to accommodate the part of the insulating tie rod 11 that protrudes relative to the bottom end face of the pole housing 1, thereby adapting to the connection and mating of the temporary stabilizer 2 with the insulating tie rod 11.

[0036] Based on the above embodiments, refer to Figure 1 and 2 .

[0037] Specifically, a mating hole 27 is provided on the fixed long beam 21, and a threaded hole (not shown in the figure) is provided on the end face of the insulating tie rod 11. The depth direction of the threaded hole is parallel to the length direction of the insulating tie rod 11. When the temporary stabilizer 2 and the pole housing 1 are relatively fixed, the axis of the mating hole 27 coincides with the axis of the mating hole 27. A mating bolt (not shown in the figure) passes through the mating hole 27 on the fixed long beam 21. The mating bolt is threaded to the insulating tie rod 11 through the threaded hole, and the radial dimension of the bolt head is larger than the diameter of the mating hole 27. After tightening the mating bolt, the mating bolt applies a pulling force in opposite directions to the insulating tie rod 11 and the fixed long beam 21, so that the end of the insulating tie rod 11 and the fixed long beam 21 can maintain a relatively fixed state.

[0038] Based on the above embodiments, such as Figure 1 and 2 As shown.

[0039] Specifically, the fixed long beam 21 has two mounting slots 26, each corresponding to a connection point between the mounting bracket and the pole housing 1. The length direction of the mounting slot 26 is radial to the insulating tie rod 11. The bottom surface of the pole housing 1 is approximately square, with a threaded hole near each of its four corners. The length direction of the fixed long beam 21 is diagonal to the bottom surface of the pole housing 1. A mounting bolt (not shown in the figure) passes through the mounting slots 26 on the fixed long beam 21. The mounting bolt passes through the fixed long beam 21 and is screwed into the threaded hole. The radial dimension of the bolt head is larger than the width of the mounting slot 26. After tightening the mounting bolt, the bottom surfaces of the fixed long beam 21 and the pole housing 1 abut against each other, simultaneously achieving relative fixation of the fixed long beam 21 and the pole housing 1.

[0040] The position of the end of the insulating tie rod 11 or the position of the threaded hole on the insulating tie rod 11 varies depending on the size of the insulating tie rod 11. The presence of the mounting waist-shaped hole 26 allows for a certain adaptive adjustment of the relative position of the temporary stabilizer 2 and the pole housing 1, ultimately achieving the positioning and matching of the fixed long beam 21, the pole housing 1, and the insulating tie rod 11.

[0041] Based on the above embodiments, such as Figure 2 As shown.

[0042] Specifically, the fixed long beam 21 includes a U-shaped component 24 and two side wing beams 25. A mating groove 23 is formed on the U-shaped component 24. The two side wing beams 25 and the U-shaped component 24 are fixedly connected, with the connection point located at the opening of the mating groove 23. With this structure, the fixed long beam 21 is simple in structure, uses less material, and is lightweight, making it easy for operators to handle. In actual implementation, the fixed long beam 21 can be formed by integrally bending a steel plate to create the U-shaped component 24 and the side wing beams 25, or it can be fixedly connected by welding.

[0043] Based on any of the above embodiments, such as Figure 2 As shown.

[0044] Specifically, the temporary stabilizer 2 also includes reinforcing ribs 22, of which there are two, fixedly connected to the two long sides of the fixed long beam 21. The length direction of the reinforcing ribs 22 is consistent with the length direction of the fixed long beam 21, and the trajectory of the reinforcing ribs 22 is the same as the trajectory of the long side of the fixed long beam 21. The reinforcing ribs 22 improve the bending deformation resistance of the fixed long beam 21, thereby improving the morphological stability of the temporary stabilizer 2.

[0045] Based on any of the above embodiments, such as Figure 2 and 3 As shown.

[0046] Specifically, when the design depth of the mating groove 23 is greater than the protrusion distance of the insulating tie rod 11 relative to the bottom end face of the pole housing 1, bending stress will be generated on the fixed long beam 21 and tensile stress will be generated on the insulating tie rod 11 after tightening the mating bolt. In order to reduce the negative impact of stress on both, one or more adjusting shims 3 are selectively provided in the mating groove 23. The adjusting shims 3 are used to change the depth of the mating groove 23 and fill the gap between the end face of the insulating tie rod 11 and the bottom of the mating groove 23 in the natural state. The adjusting shims 3 are coaxial with the mating hole 27, and the adjusting shims 3 are for the mating bolt to pass through. The specific thickness and number of adjusting shims 3 are adaptively adjusted according to the size of the gap between the end face of the insulating tie rod 11 and the bottom of the mating groove 23, thereby reducing the deformation tendency of the insulating tie rod 11 and the fixed long beam 21 after tightening the mating bolt.

[0047] Based on the above embodiments, such as Figure 3 As shown.

[0048] Specifically, since the adjusting shim 3 is not directly fixed to the temporary stabilizer 2 or the insulating tie rod 11, a positioning structure 31 is fixedly provided in the mating groove 23 during the installation of the temporary stabilizer 2 to enable the adjusting shim 3 to be quickly positioned within the mating groove 23 to be coaxial with the mating hole 27. In this embodiment, the positioning structure 31 is a positioning ridge, which is fixedly connected to the groove wall of the mating groove 23. The length direction of the positioning ridge is parallel to the axis of the mating hole 27. The number of positioning ridges must be greater than or equal to three, and the angular span of these positioning ridges in the circumferential direction must be greater than 180°. When the edge of the adjusting shim 3 contacts all the positioning ridges simultaneously, the adjusting shim 3 and the mating hole 27 are coaxial, thereby enabling rapid positioning of the adjusting shim 3. It also allows all the adjusting shims 3 to be neatly arranged when there are multiple adjusting shims 3, and prevents each adjusting shim 3 from sliding out of the mating groove 23 laterally.

[0049] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0050] Based on the above embodiments, such as Figure 3 As shown.

[0051] Specifically, an elastic buffer pad 4 is fixedly connected to the bottom of the mating groove 23. The elastic buffer pad 4 is made of rubber, is annular in shape, and coaxial with the mating hole 27. The elastic buffer pad 4 has a through hole for the adjusting bolt to pass through, and the diameter of the through hole is slightly larger than the diameter of the mating hole 27. After tightening the adjusting bolt, the adjusting shim 3 closest to the bottom of the mating groove 23 and the elastic buffer pad 4 abut against each other. The elastic buffer pad 4 plays a vibration buffering role between the temporary stabilizer 2 and the adjusting shim 3. When the temporary stabilizer 2 and the pole housing 1 are connected, when the temporary stabilizer 2 is subjected to external force, its own vibration tendency or deformation tendency can be weakened by the elastic buffer pad 4, thereby reducing the force on the insulating tie rod 11 and providing structural protection for the insulating tie rod 11.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
