Description

Technical Field

[0001] This utility model relates to the field of switchgear, and more particularly to a pull rod assembly for a solid-sealed pole, a solid-sealed pole, and an adjusting device for adjusting the pull rod assembly for adjusting the solid-sealed pole. Background Technology

[0002] The contact spacing of a high-voltage circuit breaker affects its breaking capacity and withstand voltage level. The vacuum interrupter, as the core component of the circuit breaker, contains stationary and moving contacts. The moving contact includes a moving conductive rod and moving contact plates, while the stationary contact consists of stationary contact plates. The contact spacing of the vacuum interrupter is a crucial parameter. The contact spacing refers to the distance between the moving and stationary contact plates that ensures the vacuum interrupter can disconnect. Whether the contact spacing is within the design range directly affects the performance and safety of the high-voltage circuit breaker. Therefore, the contact spacing of high-voltage circuit breakers must be calibrated before leaving the factory.

[0003] In the solid-sealed terminal block, the insulating tie rod is fixed to the moving contact, specifically to the moving conductive rod. Movement of the insulating tie rod causes the moving contact to contact or move away from the stationary contact. Currently, calibrating the contact gap requires manual adjustment of the effective length of the insulating tie rod in the solid-sealed terminal block. However, precise manual adjustment relies heavily on experience, resulting in low adjustment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a tie rod assembly for a solidified pole, which is beneficial to improving the adjustment efficiency of the effective length of the insulating tie rod.

[0005] Another objective of this invention is to provide a solid-sealed pole post, which facilitates the improvement of the adjustment efficiency of the effective length of the insulating tie rod.

[0006] Another object of this invention is to provide an adjustment device that can be used to adjust the tie rod assembly of the aforementioned solidified pole.

[0007] This invention provides a tie rod assembly for a solidified electrode post, comprising an insulating tie rod, an adjusting nut, a clamping nut, and a connector. One end of the insulating tie rod is used to connect to the moving contact of the vacuum interrupter chamber of the solidified electrode post. The adjusting nut is sleeved on the insulating tie rod and threadedly connected to it. The outer circumferential surface of the adjusting nut has circumferentially arranged teeth. The clamping nut is sleeved on the insulating tie rod and threadedly connected to it. The connector is slidably sleeved on the insulating tie rod and located between the adjusting nut and the clamping nut. The connector can be clamped by the adjusting nut and the clamping nut to fix its position on the insulating tie rod.

[0008] The tie rod assembly of this solid-sealed pole has a toothed adjusting nut, which can be turned by a mechanized gear transmission. This mechanized gear transmission allows for precise control of the adjusting nut's rotation angle, thus improving the efficiency of adjusting the effective length of the insulating tie rod.

[0009] In another illustrative embodiment of the tie rod assembly of the solidified pole, the adjusting nut has angle marking structures evenly distributed along its circumference to identify the rotation angle of the adjusting nut. This facilitates the verification of the rotation angle.

[0010] In another illustrative embodiment of the tie rod assembly of the fixed pole, the angle marking structure is a wedge-shaped groove recessed into the axial end face of the adjusting nut and extending radially. This structure is easy to manufacture, and the pointed tip of the wedge-shaped groove facilitates more accurate identification of the rotation angle.

[0011] In another illustrative embodiment of the tie rod assembly of the solidified pole, a key or keyway is formed at the other end of the insulating tie rod to form a key engagement with an external fastener, thereby achieving circumferential fixation of the insulating tie rod. This prevents the torque generated by turning the adjusting nut and clamping nut during adjustment from being transmitted to the moving contact via the insulating tie rod.

[0012] This utility model also provides a solid-sealed pole, which includes the above-mentioned tie rod assembly.

[0013] In another illustrative embodiment of the solid-sealed terminal, the insulating housing of the solid-sealed terminal is provided with an operating port. The operating port corresponds to the adjusting nut.

[0014] This invention also provides an adjustment device for adjusting the aforementioned tie rod assembly of the solidified pole. The adjustment device includes a support body, a terminal gear, and a drive mechanism. The terminal gear is rotatably mounted on the support body and engages with the teeth of the adjusting nut. The drive mechanism is mounted on the support body and is capable of driving the terminal gear to rotate, thereby adjusting the position of the adjusting nut on the insulating tie rod. This adjustment device can improve the adjustment efficiency of the effective length of the insulating tie rod.

[0015] In another illustrative embodiment of the adjusting device, the support body is a hollow shell structure with an insertion portion. The insertion portion is flat and strip-shaped. A terminal gear is rotatably fitted into the end of the insertion portion and extends out of the insertion portion along its length. The portion of the terminal gear extending out of the insertion portion is used to engage the adjusting nut. The axis of the terminal gear is parallel to the thickness direction of the insertion portion. This structure is compact, which helps to reduce the volume of the insertion portion, thereby minimizing the operating opening.

[0016] In another illustrative embodiment of the adjusting device, the adjusting device further includes several transmission gears. These transmission gears are rotatably disposed within the insertion section and mesh sequentially along the length of the insertion section. The foremost transmission gear meshes with the terminal gear. A drive mechanism can drive the rearmost transmission gear to rotate. This facilitates a reduction in the volume of the insertion section, thereby minimizing the operating opening.

[0017] In another illustrative embodiment of the adjusting device, the adjusting device further includes a bracket, a first adjusting seat, a second adjusting seat, and a third adjusting seat. The first adjusting seat is movably connected to the bracket in a vertical direction. The second adjusting seat is movably connected to the first adjusting seat in a first horizontal direction. The third adjusting seat is movably connected to the second adjusting seat in a second horizontal direction perpendicular to the first horizontal direction. The supporting body is connected to the third adjusting seat. This facilitates adjustment of the position of the supporting body and makes it convenient to use.

[0018] In another illustrative embodiment of the adjusting device, the adjusting device further includes a fixing rod. One end of the fixing rod has a key or keyway to form a key engagement with the end of the insulating pull rod, thereby achieving circumferential fixation of the insulating pull rod. This prevents the torque generated by the turning of the adjusting nut and clamping nut during adjustment from being transmitted to the moving contact through the insulating pull rod.

[0019] In another illustrative embodiment of the adjusting device, the adjusting device further includes an adjusting sleeve. The adjusting sleeve can be fitted onto the outside of the fixed rod, and one end is fitted onto the clamping nut and forms a key engagement with the clamping nut. This facilitates operation.

[0069] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0070] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0071] In this document, terms such as "first," "second," etc., do not indicate degree of importance or order, but are used only to distinguish them from each other for the purpose of document description. Nouns and pronouns relating to persons in this patent application are not limited to specific genders.

[0072] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.

[0073] Figure 1 This is a schematic diagram of one embodiment of the tie rod assembly for a solidified pole. Figure 2 for Figure 1 The diagram shows the exploded state of the tie rod assembly. Figure 3 For use Figure 1 The diagram shows a structural schematic of the solidified terminal block of the tie rod assembly. This solidified terminal block is used, for example, in high-voltage circuit breakers, but is not limited thereto.

[0074] like Figures 1 to 3 As shown, the tie rod assembly of the solidified pole in this illustrative embodiment includes an insulating tie rod 10, an adjusting nut 20, a clamping nut 30, and a connector 40. One end of the insulating tie rod 10 along its length direction A (i.e., Figures 1 to 3 The upper end of the middle) is used to connect the moving contact D of the vacuum interrupter 101 of the solid-sealed pole 100.

[0075] The adjusting nut 20 is sleeved on the insulating rod 10 and threadedly connected to the insulating rod 10 (threads are not shown in the figure). By turning the adjusting nut 20, its position on the insulating rod 10 along the length direction A can be adjusted. Figure 4 This is a schematic diagram of the adjusting nut, where C represents the circumferential direction of the adjusting nut 20 and Z represents the axial direction of the adjusting nut 20. Figure 4 As shown, the outer circumferential surface of the adjusting nut 20 is formed with gear teeth 21 arranged along its circumferential direction C. Figure 4 Only one gear tooth 21 is schematically shown in the diagram, thus enabling the adjusting nut 20 to function as a gear. From another perspective, the adjusting nut 20 can be understood, for example, as a gear that is threaded onto the insulating pull rod 10, with the axis of the gear coinciding with the axis of the thread.

[0076] The clamping nut 30 is sleeved on the insulating rod 10 and threadedly connected to the insulating rod 10 (threads are not shown in the figure). The position of the clamping nut 30 on the insulating rod 10 along the length A of the insulating rod 10 can be adjusted by turning the clamping nut 30.

[0077] The connector 40 is slidably fitted onto the insulating rod 10. More specifically, it is slidably fitted onto the insulating rod 10 along its length direction A and the opposite direction of length direction A, and the connector 40 is located between the adjusting nut 20 and the clamping nut 30. The connector 40 can be clamped by the adjusting nut 20 and the clamping nut 30 to fix its position on the insulating rod 10 along its length direction A. The connector 40 is used to connect an external drive unit, which can drive the insulating rod 10 to move along its length direction A and the opposite direction of length direction A via the connector 40, thereby driving the moving contact D to move and realize the opening and closing of the circuit. This drive unit is, for example, part of a high-voltage circuit breaker. The effective length of the insulating rod 10 is, for example, expressed as the distance along the length direction A from the end of the insulating rod 10 used to connect the moving contact D to the connector 40. As an example, the distance along the length direction A from the end of the insulating rod 10 used to connect the moving contact D to the connector 40 is, for example, expressed as... Figure 6The distance from the top of the flexible conductive element 105 to the center of the connector along the length direction A is, for example... Figure 6 The distance B in the figure is shown.

[0078] The following exemplarily describes the adjustment method of the tie rod assembly of the solidified pole in this schematic embodiment during the calibration process of the contact opening distance of a high-voltage circuit breaker. When it is necessary to adjust the effective length of the insulating tie rod 10 of the solidified pole, first, the clamping nut 30 is turned to move it away from the adjusting nut 20 to allow adjustment space for the adjusting nut 20 and the connecting member 40. Then, the adjusting nut 20 is turned to adjust its position on the insulating tie rod 10. Finally, the clamping nut 30 is turned closer to the adjusting nut 20 until it clamps the connecting member 40 with the adjusting nut 20 and reaches the set torque. During the process, the insulating tie rod 10 remains fixed, and the connecting member 40 moves but does not rotate, for example. Since the insulating tie rod 10 is connected to the moving contact D, the movement of the insulating tie rod 10 drives the movement of the moving contact D, and the movement distance of the insulating tie rod 10 can determine the contact opening distance. As an example, the distance that the insulating rod 10 needs to be pulled can be predetermined in other ways, and the movement distance of the insulating rod 10 can be precisely adjusted by turning the adjusting nut 20.

[0079] Since the adjusting nut 20 has gear teeth 21, the adjusting nut 20 can be turned by mechanical gear transmission. Mechanical gear transmission can facilitate precise control of the rotation angle of the adjusting nut 20, thus improving the adjustment efficiency of the effective length of the insulating rod.

[0080] Specifically, adjustment can be achieved, for example, through the adjustment device provided by this utility model. Figure 5 This is a schematic diagram illustrating one embodiment of the adjusting device. (Example) Figure 5 As shown, the adjusting device 200 includes a support body 60, a terminal gear 71, and a drive mechanism 80. The terminal gear 71 is rotatably mounted on the support body 60 and is used to mesh with the teeth 21 of the adjusting nut 20. The drive mechanism 80 is mounted on the support body 60 and is capable of actuating to drive the terminal gear 71 to rotate. The drive mechanism 80 is, for example, a motor to facilitate automatic control, but is not limited thereto. Figure 6 To display Figure 5 A schematic diagram showing the operating state of the adjustment device. (As shown) Figure 6 As shown, in use, the adjusting device 200 can be inserted into the fixed end post 100, so that the terminal gear 71 meshes with the gear teeth 21 of the adjusting nut 20. Then, the drive mechanism 80 is activated to drive the terminal gear 71 to rotate, thereby causing the adjusting nut 20 to rotate relative to the insulating rod 10. This adjusting device can help improve the adjustment efficiency of the effective length of the insulating rod 10.

[0081] like Figure 4As shown, in a schematic embodiment of the tie rod assembly of the solidified pole, the adjusting nut 20 is provided with six angle marking structures 22 evenly arranged along its circumferential direction C. Figure 4 Only one of these is schematically shown in the diagram, used to identify the rotation angle of the adjusting nut 20. This facilitates the verification of the rotation angle. In some cases, the operator can also rotate the adjusting nut 20 using a simple tool such as a screwdriver. In this case, the angle marking structure 22 allows the operator to easily observe the rotation angle of the adjusting nut 20. Specifically, the angle marking structure 22 is, for example, a wedge-shaped groove recessed into the axial end face of the adjusting nut 20 and extending radially, that is, the wedge-shaped groove extends to the circumferential side of the adjusting nut 20. This structure is easy to manufacture, and the pointed tip of the wedge-shaped groove facilitates more accurate identification of the rotation angle. However, this is not the only limitation; in other illustrative embodiments, angle marking can be implemented using other structures. In this illustrative embodiment, the adjusting nut 20 is provided with six angle marking structures 22, but this is not the only limitation. In other illustrative embodiments, the number of angle marking structures 22 can be adjusted as needed.

[0082] like Figure 1 As shown, in a schematic embodiment of the tie rod assembly of the solidified pole, the other end of the insulating tie rod 10 along its length direction A (i.e. Figure 1 A key 11 is formed at the lower end of the insulating rod 10. The key 11 can engage with the keyway of the external fastener to achieve circumferential fixation of the insulating rod 10. This prevents the torque generated by the turning of the adjusting nut 20 and the clamping nut 30 from being transmitted to the moving contact D through the insulating rod 10 during adjustment. In other illustrative embodiments, the key 11 can also be replaced with a keyway structure to engage with the key of the external fastener, which can also achieve the same function of circumferential fixation of the insulating rod 10.

[0083] like Figure 1 As shown in the schematic embodiment of the tie rod assembly of the solidified pole, a washer 50 is provided between the clamping nut 30 and the connector 40, for example, to prevent the adjusting nut 20, the clamping nut 30 and the connector 40 from loosening during the use of the solidified pole, but is not limited thereto.

[0084] This utility model also provides a solid-sealed pole. Figure 3 This is a schematic structural diagram of one embodiment of a solidified terminal block, which is used, for example, in a high-voltage circuit breaker, but is not limited thereto. The solidified terminal block 100 includes an insulating housing 102, a vacuum interrupter 101, an upper terminal block 103, a lower terminal block 104, a flexible conductive element 105, and... Figure 1The pull rod assembly is shown. The upper terminal block 103 connects to the stationary contact J of the vacuum interrupter 101, and the lower terminal block 104 connects to the moving contact D of the vacuum interrupter 101 via a flexible conductive element 105. The vacuum interrupter 101, upper terminal block 103, and lower terminal block 104 are enclosed within an insulating housing 102. One end of the insulating pull rod 10 along its length direction A (i.e....) Figure 3 The upper end of the terminal block is connected to the moving contact D of the vacuum interrupter 101. This solid-sealed pole can improve the adjustment efficiency of the effective length of the insulating tie rod.

[0085] like Figure 3 As shown, in the illustrative embodiment, the solidified pole 100 has, for example, an operating port 106 reserved in its insulating housing 102. The operating port 106 is opposite to the adjusting nut 20, so that the adjusting device 200 can enter the solidified pole through the operating port 106 to turn the adjusting nut 20.

[0086] Figure 7 for Figure 5 The diagram shows an exploded view of part of the structure of the regulating device. (See attached diagram.) Figure 5 and Figure 7 As shown in the schematic embodiment of the adjusting device, the support body 60 is a hollow shell structure composed of two parts and has an insertion part 61. The insertion part 61 is flat and strip-shaped. A terminal gear 71 is rotatably fitted into the end of the insertion part 61 and extends out of the insertion part 61 along the length direction L of the insertion part 61. The portion of the terminal gear 71 extending out of the insertion part 61 is used to engage the adjusting nut 20. The axis of the terminal gear 71 is parallel to the thickness direction T of the insertion part 61. In use, the insertion part 61 of the adjusting device 200 is inserted into the operating port 106 of the sealing pole 100 along the length direction L of the insertion part 61, so that the terminal gear 71 engages with the adjusting nut 20. This structure is compact, which helps to reduce the volume of the insertion part 61, so as to minimize the operating port 106.

[0087] like Figure 7 As shown, in a schematic embodiment of the adjusting device, the adjusting device further includes several transmission gears 72 ( Figure 7Only two of the transmission gears 72 are schematically shown in the diagram. Several transmission gears 72 are rotatably disposed within the insertion portion 61 and mesh sequentially along the length L of the insertion portion 61. The foremost transmission gear 72 meshes with the terminal gear 71. The terminal gear 71 and several transmission gears 72 are arranged along the length L of the insertion portion 61 and mesh sequentially, which helps to reduce the volume of the insertion portion 61, thereby minimizing the operating opening 106. The drive mechanism 80 is capable of driving the rearmost transmission gear 72 to rotate. Specifically, in this illustrative embodiment, the drive mechanism 80 drives the rearmost transmission gear 72 to rotate via a transmission mechanism 73, which includes, for example, a synchronous belt drive mechanism, but is not limited to this. In other illustrative embodiments, the transmission mechanism 73 may also be other transmission structures. In this illustrative embodiment, the number of transmission gears 72 can be adjusted as needed.

[0088] like Figure 5 As shown in the schematic embodiment of the adjustment device, the adjustment device further includes a bracket 90, a first adjustment seat 91, a second adjustment seat 92, and a third adjustment seat 93. During adjustment, the sealing pole 100 is fixed to the bracket 90, for example. The first adjustment seat 91 is movably connected to the bracket 90 along the vertical direction S and the opposite direction of the vertical direction S. The second adjustment seat 92 is movably connected to the first adjustment seat 91 along the first horizontal direction D1 and the opposite direction of the first horizontal direction D1. The third adjustment seat 93 is movably connected to the second adjustment seat 92 along a second horizontal direction D2 perpendicular to the first horizontal direction D1 and the opposite direction of the second horizontal direction D2. The support body 60 is connected to the third adjustment seat 93. Both the first horizontal direction D1 and the second horizontal direction D2 are perpendicular to the vertical direction S.

[0089] When the three-phase fixed-seal poles of the high-voltage circuit breaker are fixed to the bracket 90 in the product-defined arrangement, the first horizontal direction D1 is, for example, parallel to the arrangement direction of the three-phase fixed-seal poles of the high-voltage circuit breaker. Adjusting the position of the second adjusting seat 92 along the first horizontal direction D1 facilitates switching between the three-phase fixed-seal poles of the support body 60. The second horizontal direction D2 is, for example, parallel to the length direction L of the insertion part 61, thereby facilitating the insertion part 61 into the operating port 106 of the fixed-seal pole 100, but is not limited thereto. The vertical direction S is, for example, parallel to the height direction of the fixed-seal poles, to accommodate different models of fixed-seal poles. This facilitates adjustment of the position of the support body 60 for convenient use.

[0090] In an illustrative embodiment, the adjustment device may further include, for example, a drive module (not shown) capable of driving the first adjustment seat 91, the second adjustment seat 92, and the third adjustment seat 93 to move. The drive module may be, for example, but is not limited to, a motor, thereby facilitating automatic control. In an illustrative embodiment, the first adjustment seat 91, the second adjustment seat 92, and the third adjustment seat 93, and their corresponding drive modules, may be integrated, for example, into three linear motors arranged perpendicularly in pairs.

[0091] Figure 8 This is a schematic diagram illustrating another illustrative embodiment of the adjusting device. The adjusting device of this illustrative embodiment... Figure 5 The adjustment device shown is modified by adding a fixing rod 94 and an adjusting sleeve 95. For example... Figure 8 As shown, one end of the fixing rod 94 (i.e. Figure 8 The upper end of the insulating rod 10 has a keyway 941, which can engage with the key 11 at the end of the insulating rod 10 to achieve circumferential fixation of the insulating rod 10. This prevents the torque generated by the turning of the adjusting nut 20 and clamping nut 30 from being transmitted to the moving contact D through the insulating rod 10 during adjustment. In other illustrative embodiments, one end of the fixing rod 94 may also have a key, which can engage with the keyway at the end of the insulating rod 10 to achieve circumferential fixation of the insulating rod 10.

[0092] like Figure 8 As shown, the adjusting sleeve 95 can be fitted onto the outside of the fixing rod 94, and one end is fitted onto the clamping nut 30, forming a key engagement with the clamping nut 30. In use, the insulating pull rod 10 can be fixed via the fixing rod 94. With the insulating pull rod 10 fixed, the clamping nut 30 can be turned via the adjusting sleeve 95. This facilitates operation.

[0093] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0094] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent implementation schemes or modifications made without departing from the spirit of the present utility model, such as combinations, divisions or repetitions of features, should be included within the scope of protection of the present utility model.
