Description

Technical Field

[0001] This application relates to the field of vacuum interrupter installation structure technology, and specifically to an installation device for a vacuum interrupter. Background Technology

[0002] A pole-mounted circuit breaker is a primary device used in high-voltage power systems, mainly in urban and rural power distribution networks. Its main function is to disconnect or connect lines under normal conditions, and in the event of a short-circuit fault, to manually or automatically switch the faulty line through operation or relay protection devices, thereby protecting the power grid. The assembly of a pole-mounted circuit breaker requires manual adjustment of the high end of the double-ended bolts inside the insulation components and the height of the insulation tie rod, as well as tightening of the bolts and fasteners, to facilitate subsequent adjustment of the circuit breaker's switching mechanical characteristic parameters.

[0003] Generally speaking, pole-mounted circuit breakers consist of three phases, A, B, and C, and each unit includes three vacuum interrupters. In the current assembly process, the vacuum interrupters are usually installed one by one. This inevitably leads to differences in the height of the three vacuum interrupters, that is, inconsistencies in the relative installation status of the double-ended bolts, insulating tie rods, and vacuum interrupters.

[0004] This presents the following problems: First, during installation, because each component needs to be installed individually, the relative installation positions of the double-ended bolts, insulating tie rods, and vacuum interrupters need to be repeatedly measured, resulting in low installation efficiency and a high risk of erroneous readings, leading to rework. Second, only one vacuum interrupter can be installed at a time, making the installation process cumbersome and inefficient. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0039] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 8 As shown, this embodiment provides an installation device 100 for a vacuum interrupter 200, including a base 1, a clamp 2, a first limiting rod 3, a first limiting piece 41, and a second limiting piece 42; the clamp 2 is disposed on the base 1 and is used to clamp the stationary contact of the vacuum interrupter 200; one end of the first limiting rod 3 is connected to the base 1, and the other end of the first limiting rod 3 extends in a direction away from the base 1; the first limiting piece 41 and the second limiting piece 42 are respectively movably disposed on the first limiting rod 3; wherein, the first limiting piece 41 is disposed corresponding to the double-ended screw 300, and the second limiting piece 42 is disposed corresponding to the insulating pull rod 400.

[0042] To facilitate understanding by relevant technical personnel, the working process / working principle of the above technical solution will be explained below.

[0043] When installing the vacuum interrupter 200, first use the clamp 2 to clamp the stationary contact of the vacuum interrupter 200. Then, screw the double-ended screw 300 into the moving contact of the vacuum interrupter 200. Then, control the relative distance between the moving contact of the vacuum interrupter 200 and the top of the double-ended screw 300 to the required distance by rotating the double-ended screw 300. Then, adjust the position of the first limiting piece 41 so that it corresponds to the double-ended screw 300 and lock the first limiting piece 41 in place. Then, screw the insulating rod 400 onto the top of the double-ended screw 300, and adjust the relative distance between the top of the insulating rod 400 and the double-ended screw 300 to the required distance by rotating the insulating rod 400. Then, adjust the position of the second limiting piece 42 so that it corresponds to the insulating rod 400 and lock the second limiting piece 42 onto the second limiting piece 42. At this time, the standard installation and docking process of a vacuum interrupter 200, insulating rod 400 and double-ended screw 300 is completed.

[0044] When installing the next vacuum interrupter 200, insulating tie rod 400, and double-ended screw 300, remove the previously installed vacuum interrupter 200, insulating tie rod 400, and double-ended screw 300 (simply loosen clamp 2), and then repeat the above installation process.

[0045] In other words, the principle by which the installation device 100 for vacuum interrupters of this application can quickly complete the installation of multiple vacuum interrupters 200 is as follows: Since the multiple vacuum interrupters 200, multiple insulating tie rods 400, and multiple double-ended screws 300 used in the same pole-mounted circuit breaker are all of the same specification, after the initial assembly is completed using the installation device 100 for vacuum interrupters of this application, the relative positions of the clamp 2, the first limiting piece 41, and the second limiting piece 42 fixedly installed on the base 1 are already defined, and they correspond to the relative positions of the vacuum interrupter 200, the double-ended screw 300, and the insulating tie rod 400, respectively. The operator can quickly and accurately complete the assembly of the remaining vacuum interrupters 200, insulating tie rods 400, and double-ended screws 300 with the help of the clamp 2, the first limiting piece 41, and the second limiting piece 42.

[0046] Thus, through the above technical solution, firstly, the installation device 100 for vacuum interrupters of this application only needs to measure the relative distance during the first assembly process, and the relative distance does not need to be measured in the remaining assembly processes. This can effectively avoid the process of repeated measurement, effectively improve installation efficiency, and since only one measurement is required, it can also effectively avoid the problem of reading errors caused by multiple measurements. In addition, it can effectively ensure that all vacuum interrupters 200 can be installed with a relatively consistent standard, which can effectively reduce the probability of rework.

[0047] Secondly, the installation device 100 for vacuum interrupters in this application can quickly and accurately define the relative positions of the double-ended bolts, insulating tie rods 400 and vacuum interrupters 200, so as to enable the rapid installation of multiple vacuum interrupters 200 at one time, which can effectively improve the installation efficiency.

[0048] In existing related technologies, during the installation process, a wrench is generally used to fix the stationary contact of the vacuum interrupter 200, and then the double-ended screw 300 is screwed into the moving contact of the vacuum interrupter 200. During the operation, the hand holding the wrench will rotate or move, causing the wrench to shift or rotate. This can easily lead to damage to the threads of the stationary contact of the vacuum interrupter 200 caused by the shifted or rotated wrench, affecting the efficiency of the subsequent assembly of the inlet busbar.

[0049] In view of this, in one embodiment of this application, such as Figures 1 to 3 , Figure 8As shown, the clamp 2 of this application may include an elastic element 21, a first clamping block 22, a second clamping block 23, and a rotating screw 24. The two ends of the elastic element 21 are respectively connected to the first clamping block 22 and the base 1. The second clamping block 23 is fixedly installed on the base 1. The second clamping block 23 has a mounting through hole for the rotating screw 24 to pass through. The rotating screw 24 passes through the mounting through hole and is threadedly connected to the first clamping block 22. The first clamping block 22 has a first notch 221, and the second clamping block 23 has a second notch 231. The first notch 221 and the second notch 231 together form a receiving groove for accommodating the stationary contact of the vacuum interrupter 200.

[0050] Thus, on the one hand, the clamp 2 of this application is installed on the base 1, and there will be no displacement or rotation during the assembly process, which can effectively avoid the problem of damage to the thread of the stationary contact, and thus effectively ensure the efficiency when assembling the inlet busbar later; on the other hand, the clamp 2 of this application can stably and reliably hold the stationary contact of the vacuum interrupter 200, so as to complete the assembly process.

[0051] The working process / principle of the clamp 2 in this application is as follows: By rotating the rotating screw 24, the rotating screw 24 drives the first clamping block 22 to move towards the second clamping block 23, thereby achieving the effect of the first clamping block 22 and the second clamping block 23 jointly clamping the vacuum interrupter 200. When disassembly is required, simply rotate the rotating screw 24 in the opposite direction. Under the action of the rotating screw 24 and the elastic element 21, the second clamping block 23 will move away from the first clamping block 22 and the second clamping block 23, thereby achieving the effect of the first clamping block 22 and the second clamping block 23 releasing the vacuum interrupter 200.

[0052] It is understandable that, such as Figure 1 and Figure 3 As shown, the rotating screw 24 of this application can also be used with a handle to facilitate rotation of the rotating screw 24. In addition, the rotating screw 24 can also adopt a ratchet-type fixing clamping method to facilitate self-locking.

[0053] In one embodiment of this application, such as Figure 2 and Figure 8 As shown, a groove 11 can be formed on the base 1 of this application, and the first clamping block 22 is movably installed in the groove 11. In this way, the first clamping block 22 will move closer to or further away from the second clamping block 23 along a fixed preset direction under the action of the rotating screw 24 and the groove 11, so as to ensure the clamping effect and clamping state, thereby effectively avoiding damage to the stationary contact caused by the first clamping block 22 and the second clamping block 23.

[0054] In one embodiment of this application, such as Figures 1 to 3As shown, the installation device 100 for the vacuum interrupter of this application may further include a second limiting rod 5 disposed opposite to the first limiting rod 3, one end of the second limiting rod 5 being installed on the second clamping block 23; the installation device 100 for the vacuum interrupter includes two first limiting pieces 41 and two second limiting pieces 42, the two first limiting pieces 41 being disposed opposite to each other and movably mounted on the first limiting rod 3 and the second limiting rod 5 respectively, and the two second limiting pieces 42 being disposed opposite to each other and movably mounted on the first limiting rod 3 and the second limiting rod 5 respectively.

[0055] Thus, the installation device 100 for the vacuum interrupter of this application has two first limiting plates 41 and second limiting plates 42 arranged opposite to each other. This not only effectively ensures the reliable and accurate assembly of the vacuum interrupter 200, the double-ended screw 300 and the insulating tie rod 400, but also facilitates the formation of multiple relative alignment reference positions for the vacuum interrupter 200, the double-ended screw 300 and the insulating tie rod 400, thereby further improving the assembly efficiency.

[0056] In one embodiment of this application, such as Figures 1 to 3 ,as well as Figure 8 As shown, the mounting device 100 for the vacuum interrupter 200 of this application may further include two opposing support bars 61, which are respectively mounted on the first limiting rod 3 and the second limiting rod 5. The two support bars 61 are used to jointly support the lower end of the vacuum interrupter 200. In this way, the two support bars 61 arranged in this manner can stably and reliably bear the weight of the vacuum interrupter 200. Combined with the clamp 2, this can effectively ensure the reliability of the position and shape of the vacuum interrupter 200 during the assembly process, so as to facilitate quick and reliable assembly.

[0057] In one embodiment of this application, such as Figures 1 to 3 , Figure 7 and Figure 8 As shown, the installation device 100 for the vacuum interrupter of this application may further include two sets of support components 62. The two sets of support components 62 are respectively disposed above and below the support bar 61. Each set of support components 62 includes a first support member 621 and a second support member 622 disposed opposite to each other. The first support member 621 includes a first elastic body 6211 and a first support block 6212 connected to each other. The second support member 622 includes a second elastic body 6221 and a second support block 6222 connected to each other. The end of the first elastic body 6211 away from the first support block 6212 is connected to the first limiting rod 3. The first support block 6212 is used to abut against the side of the vacuum interrupter 200. The end of the second elastic body 6221 away from the second support block 6222 is connected to the second limiting rod 5. The second support block 6222 is used to abut against the side of the vacuum interrupter 200.

[0058] In this way, the two sets of support components 62 can be respectively set at the upper and lower ends of the vacuum interrupter 200, so as to avoid the rotation problem that may occur in the vacuum interrupter 200 when the double-ended screw 300 is screwed into the moving contact of the vacuum interrupter 200. This can further improve the reliability of the position and shape of the vacuum interrupter 200 during the assembly process, so as to facilitate installation and reliably complete the assembly process.

[0059] In one embodiment of this application, such as Figure 1 , Figure 3 and Figure 7 As shown, the installation device 100 for the vacuum interrupter of this application may further include two elastic support columns 63 arranged opposite to each other. The two elastic support columns 63 are respectively installed on the first limiting rod 3 and the second limiting rod 5. The elastic support columns 63 are arranged between the two sets of support components 62, and the two elastic support columns 63 are used to abut against the upper end of the vacuum interrupter 200.

[0060] In this way, the two elastic pillars can be positioned to abut against the outer shell of the vacuum interrupter 200, which can further improve the reliability of the position and shape of the vacuum interrupter 200 during the assembly process, so as to facilitate quick and reliable assembly.

[0061] In one embodiment of this application, such as Figure 1 and Figure 3 As shown, the installation device 100 for a vacuum interrupter in this application may further include a first connecting rod 71 and a second connecting rod 72. The two ends of the first connecting rod 71 are respectively connected to the ends of the two first limiting plates 41 away from the first limiting rod 3, and the two ends of the second connecting rod 72 are respectively connected to the ends of the two second limiting plates 42 away from the second limiting rod 5.

[0062] In this way, the first connecting rod 71 and the second connecting rod 72, which are configured in this way, can connect the first limiting piece 41 and the second limiting piece 42 respectively, so as to improve the stability of their position and thus further improve the accuracy of installation.

[0063] In this application, it is understood that the connection method between the first limiting piece 41 and the second limiting piece 42 and the first connecting rod 71, the second connecting rod 72, the first limiting rod 3 and the second limiting rod 5 respectively can be: the first connecting rod 71, the second connecting rod 72, the first limiting rod 3 and the second limiting rod 5 are all partially or entirely threaded sections, and the first limiting piece 41 and the second limiting piece 42 are installed on them by fastening with double nuts, which not only facilitates installation and disassembly, but also effectively simplifies the structure.

[0064] In one embodiment of this application, such as Figure 1 and Figure 3As shown, the installation device 100 for a vacuum interrupter in this application may further include a first scale rod 81 and a second scale rod 82, a first limiting rod 3 and a second limiting rod 5 located between the first scale rod 81 and the second scale rod 82, and scales respectively provided on the first scale rod 81 and the second scale rod 82. One end of the first scale rod 81 is installed on the base 1, and the second scale rod 82 is installed on the second clamping block 23.

[0065] In this way, the relative distance between the moving contact of the vacuum interrupter 200 and the top of the double-ended screw 300, as well as the relative distance between the top of the insulating pull rod 400 and the double-ended screw 300, can be directly read by the first scale rod 81 and the second scale rod 82 as set up in this way. There is no need to use a steel ruler or vernier caliper, which can effectively simplify the installation steps and reduce the installation difficulty, thereby effectively improving the installation efficiency.

[0066] In one embodiment of this application, such as Figures 3 to 6 As shown, the mounting device 100 for a vacuum interrupter of this application may further include a stabilizing rod 9; one end of the stabilizing rod 9 is rotatably mounted on the end of the first scale rod 81 away from the base 1, and the other end of the stabilizing rod 9 is detachably connected to the second scale rod 82; or, one end of the stabilizing rod 9 is rotatably mounted on the end of the second scale rod 82 away from the second clamping block 23, and the other end of the stabilizing rod 9 is detachably connected to the first scale rod 81; wherein, a first protrusion 91 and a second protrusion 92 are formed on the stabilizing rod 9, a first groove 31 matching the first protrusion 91 is formed on the first limiting rod 3, and a second groove 51 matching the second protrusion 92 is formed on the second limiting rod 5.

[0067] In this way, the stabilizer bar 9, the first groove 31 and the second groove 51 can effectively improve the structural stability of the entire structure, and thus effectively improve the stability of the relative positions of the first limiting piece 41, the second limiting piece 42 and the clamp 2, thereby effectively ensuring the quickness and accuracy of the installation of the vacuum interrupter 200.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
