Description

Technical Field

[0001] This application relates to the field of high-voltage electrical equipment technology, specifically to a vacuum interrupter assembly fixture. Background Technology

[0002] Vacuum interrupters, also known as vacuum switch tubes, are core components of medium and high voltage power switches. Through the excellent insulation of the vacuum inside the tube, they enable rapid arc extinguishing and current suppression after power is cut off in medium and high voltage circuits, preventing accidents and incidents. The conductive clamp is in close contact with the moving conductive rod of the vacuum interrupter, transferring current from the external circuit (such as downstream flexible connections or cables) to the moving contact, and then through the closed contact pair to the stationary contact, forming a complete current path. If the installation position accuracy between the conductive clamp and the vacuum interrupter body cannot be ensured during assembly, the conductive clamp will not be in close contact with the moving conductive rod, reducing the reliability of the vacuum interrupter.

[0003] In the existing technology, the manual assembly of conductive clamps relies on the experience and skills of the workers, which is not only inefficient but also cannot guarantee the assembly consistency between several vacuum interrupters.

[0004] Therefore, there is an urgent need for a vacuum interrupter assembly fixture to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this application is to provide a vacuum interrupter assembly fixture that can improve the assembly efficiency of the conductive clamp and ensure assembly consistency among several vacuum interrupters.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A vacuum interrupter assembly fixture is provided, capable of assembling a conductive clamp onto the interrupter body, comprising:

[0008] The frame, on which the main body of the arc-extinguishing chamber is mounted;

[0009] A fastener is slidably connected to the frame along a first direction, which is horizontally positioned.

[0010] The arc-extinguishing chamber body is provided with a first positioning surface, and the conductive clamp is provided with a second positioning surface corresponding to the first positioning surface. The first direction is perpendicular to both the first positioning surface and the second positioning surface. The conductive clamp is connected to the fixing member and can move along the first direction, so that the second positioning surface contacts or moves away from the first positioning surface.

[0011] In some embodiments, the vacuum interrupter assembly fixture further includes a slide rail extending along the first direction, and the fixing member is slidably connected to the slide rail.

[0012] In some embodiments, the fastener is provided with a slot for engaging the conductive clip.

[0013] In some embodiments, the slide rail is provided with a first sliding hole, the frame is provided with a first sliding rod extending in a vertical direction, and the first sliding hole and the first sliding rod are slidably engaged; the slide rail is also provided with a first threaded hole that is angled to the first sliding hole and communicates with the first sliding hole, and the vacuum interrupter assembly fixture also includes a first locking bolt that is threadedly engaged with the first threaded hole.

[0014] In some embodiments, an insulating tie rod is mounted on the main body of the arc-extinguishing chamber, and the vacuum arc-extinguishing chamber assembly fixture further includes a height measuring component, which is mounted on the frame and used to detect the installation height of the insulating tie rod.

[0015] In some embodiments, the height measuring component includes a second slide rod and a pressing block. One end of the second slide rod is fixedly connected to the frame in a vertical direction. The pressing block is slidably connected to the second slide rod in a vertical direction and is movable to contact the upper end face of the insulating pull rod. The second slide rod is provided with a scale for indicating the installation height of the insulating pull rod.

[0016] In some embodiments, the pressing block is provided with a pointer that corresponds to the scale.

[0017] In some embodiments, the pressing block is provided with a second sliding hole, and the inner sidewall of the second sliding hole matches the peripheral sidewall of the second sliding rod.

[0018] In some embodiments, the second slide bar is rotatably connected to the frame with its own central axis as the pivot.

[0019] In some embodiments, a first positioning element is provided on the frame, and a second positioning element is provided on the main body of the arc extinguishing chamber to position and cooperate with the first positioning element.

[0020] The beneficial effects of this application are as follows:

[0021] The vacuum interrupter assembly fixture provided in this application has the interrupter body mounted on a frame, and a fixing member slidably connected to the frame along a first direction. The interrupter body is provided with a first positioning surface, and the conductive clamp is provided with a second positioning surface corresponding to the first positioning surface. The first direction is perpendicular to both the first and second positioning surfaces. The conductive clamp is connected to the fixing member and can move along the first direction, so that the second positioning surface contacts or moves away from the first positioning surface, thereby making the positioning surface of the conductive clamp coincide with the positioning surface of the interrupter body. When the conductive clamp is assembled onto the interrupter body, no manual adjustment is required to make the positioning surface of the conductive clamp coincide with the positioning surface of the interrupter body, which improves the assembly efficiency of the conductive clamp. Moreover, because it moves directly along the first direction through the fixing member to make the first positioning surface coincide with the second positioning surface, it can ensure the assembly consistency among several vacuum interrupters.

[0030] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0031] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0035] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0036] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0037] Figure 1 This is a structural schematic diagram of the vacuum interrupter assembly fixture provided in this embodiment. (See attached diagram.) Figure 1 As shown, the vacuum interrupter assembly fixture provided in this embodiment can assemble the conductive clamp 100 onto the interrupter body 200. The vacuum interrupter assembly fixture includes a frame 1 and a fixing member 2. The interrupter body 200 is installed on the frame 1. The fixing member 2 is slidably connected to the frame 1 along a first direction, which is horizontal. The interrupter body 200 is provided with a first positioning surface, and the conductive clamp 100 is provided with a second positioning surface corresponding to the first positioning surface. The first direction is perpendicular to both the first and second positioning surfaces. The conductive clamp 100 is connected to the fixing member 2 and can move along the first direction, so that the second positioning surface contacts or moves away from the first positioning surface.

[0038] The vacuum interrupter assembly fixture provided in this embodiment is mounted on the frame 1 via the interrupter body 200. The fixing member 2 is slidably connected to the frame 1 along the first direction. The interrupter body 200 is provided with a first positioning surface, and the conductive clamp 100 is provided with a second positioning surface corresponding to the first positioning surface. The first direction is perpendicular to both the first and second positioning surfaces. The conductive clamp 100 is connected to the fixing member 2 and can move along the first direction, so that the second positioning surface contacts or moves away from the first positioning surface, thereby making the positioning surface of the conductive clamp 100 coincide with the positioning surface of the interrupter body 200. When assembling the conductive clamp 100 onto the interrupter body 200, no manual adjustment is required to make the positioning surface of the conductive clamp 100 coincide with the positioning surface of the interrupter body 200, which improves the assembly efficiency of the conductive clamp 100. Furthermore, because it moves directly along the first direction through the fixing member 2 to make the first positioning surface coincide with the second positioning surface, the assembly consistency among several vacuum interrupters can be guaranteed.

[0039] Continue as Figure 1As shown, the vacuum interrupter assembly fixture also includes a slide rail 3, which extends along a first direction. The fixing member 2 is slidably connected to the slide rail 3, thereby guiding the movement direction of the fixing member 2 to ensure that the conductive clamp 100 moves along the first direction with the fixing member 2, and the first positioning surface and the second positioning surface can fit together.

[0040] In some embodiments, the fixing member 2 is provided with a slot for engaging the conductive clip 100, so that the conductive clip 100 can be engaged with the fixing member 2. After the conductive clip 100 is assembled into the arc-extinguishing chamber body 200, the conductive clip 100 can be quickly separated from the fixing member 2, thereby improving the assembly efficiency of the vacuum arc-extinguishing chamber assembly tooling.

[0041] Continue as Figure 1 As shown, the slide rail 3 has a first sliding hole 31, and the frame 1 is provided with a first sliding rod 11 extending in the vertical direction. The first sliding hole 31 and the first sliding rod 11 are slidably engaged. The slide rail 3 also has a first threaded hole that is angled to and communicates with the first sliding hole 31. The vacuum interrupter assembly fixture also includes a first locking bolt that is threaded into the first threaded hole. Thus, the slide rail 3 can move in the vertical direction, thereby adjusting the relative position of the conductive clamp 100 and the interrupter body 200 in the vertical direction, and thus adapting to different specifications and models of vacuum interrupters. The first positioning surface and the second positioning surface can be coplanar and correspond to each other. After adjusting the position of the conductive clamp 100 in the vertical direction, the first locking bolt can be screwed on to press against the peripheral wall of the first slide rod 11, thereby locking the relative position between the slide rail 3 and the first slide rod 11. When assembling several arc-extinguishing chambers of the same specification, it is not necessary to readjust the position of the conductive clamp 100 in the vertical direction, so that the first positioning surface and the second positioning surface are in contact, thereby improving the assembly efficiency of the vacuum arc-extinguishing chamber assembly tool conductive clamp 100.

[0042] After the conductive clamp 100 is assembled on the main body 200 of the arc-extinguishing chamber, an insulating tie rod 300 is also assembled on the main body 200 to achieve electrical isolation and transmit operating force mechanically. Whether the installation height of the insulating tie rod 300 meets the accuracy requirements can also affect the reliability of the vacuum arc-extinguishing chamber. To test the installation height of the insulating tie rod 300, such as... Figure 1As shown, the vacuum interrupter assembly fixture also includes a height measuring component 4, which is mounted on the frame 1 and used to detect the installation height of the insulating tie rod 300. Specifically, the height measuring component 4 includes a second slide rod 41 and a pressing block 42. One end of the second slide rod 41 is fixedly connected to the frame 1 in the vertical direction. The pressing block 42 is slidably connected to the second slide rod 41 in the vertical direction and can move to contact the upper end face of the insulating tie rod 300. The second slide rod 41 is provided with a scale for indicating the installation height of the insulating tie rod 300, so that the operator can determine whether the installation height of the insulating tie rod 300 meets the accuracy requirements by observing the position of the pressing block 42 corresponding to the scale.

[0043] Preferably, the pressing block 42 is provided with a pointer that corresponds to the scale, so that the staff can easily read the installation height data of the insulating pull rod 300 on the scale.

[0044] In some embodiments, the pressing block 42 is provided with a second sliding hole, the inner sidewall of the second sliding hole matches the peripheral sidewall of the second sliding rod 41, thereby ensuring that when the pressing block 42 is pressed against the upper end face of the insulating rod 300, the horizontal sway will not affect the reading of the installation height data of the insulating rod 300.

[0045] In some embodiments, the second slide bar 41 is rotatably connected to the frame 1 with its own central axis as the pivot, thereby adjusting the relative position of the pressing block 42 and the insulating pull rod 300. When assembling the insulating pull rod 300, the pressing block 42 can be moved away to avoid the pressing block 42 obstructing the assembly of the insulating pull rod 300. When measuring the installation height of the insulating pull rod 300, the pressing block 42 can be rotated to press against the upper end face of the insulating pull rod 300.

[0046] In some embodiments, a first positioning member is provided on the frame 1, and a second positioning member is provided on the arc-extinguishing chamber body 200 to position and cooperate with the first positioning member. This allows the arc-extinguishing chamber body 200 to be quickly installed on the frame 1, thereby establishing a unified first positioning surface reference. When assembling several vacuum arc-extinguishing chambers, the conductive clamp 100 can be directly installed on the fixing member 2, and the fixing member 2 can be moved along the first direction, so that the first positioning surface and the second positioning surface are coplanar. It should be noted that the specific types of the first and second positioning members are not limited here. The first and second positioning members can be positioning pins and positioning holes, or positioning protrusions and positioning grooves, as long as they can locate the installation position of the arc-extinguishing chamber body 200 relative to the frame 1.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
