Description

Technical Field

[0001] This application relates to the field of isolating grounding switch technology, and in particular to an auxiliary positioning device for installing moving contacts. Background Technology

[0002] Disconnecting grounding switches typically function as circuit isolation and grounding protection devices in power systems. The moving conductor of a disconnecting grounding switch includes an actuating head and a sliding rod. The actuating head is fitted onto the sliding rod and can move axially within its cavity. During the assembly of the disconnecting grounding switch, the accuracy of the installation position of the moving contact has a critical impact on its performance. When connecting the moving contact to the insulator, the relative position of the moving contact and the insulator must be ensured. Existing fixing methods involve manually observing and determining the relative position of the moving contact and the insulator, then fixing them together using splines. Due to the lack of effective positioning methods, it is difficult to guarantee the assembly accuracy of the moving contact and the insulator, thus causing the disconnecting grounding switch to fail to successfully complete circuit isolation or grounding operations. Summary of the Invention

[0003] In view of this, this application proposes an auxiliary positioning device for installing a moving contact, which is suitable for providing positioning support for the moving contact when it is fixed to the insulator; it includes: a flange, a first positioning component, a second positioning component, and a centering rod;

[0005] The first positioning component includes: two first support rods, a first welding plate, and a first positioning plate; the two first support rods are parallel to each other in their length direction, and the first welding plate is fixedly disposed at the top of the two first support rods; the first positioning plate is fixedly disposed on the side of the first welding plate away from the first support rods; the first positioning plate is provided with a first positioning hole, which is suitable for the sliding rod to pass through the first positioning hole and abut against the first welding plate;

[0006] The second positioning assembly includes two second support rods, a second welding plate, and a second positioning plate. The two second support rods are parallel to each other in their length direction, and the second welding plate is fixedly installed at the top of the two second support rods. The second positioning plate is fixedly installed on the side of the second welding plate away from the second support rods. A second positioning hole is provided on the second positioning plate. The second positioning hole is coaxial with the first positioning hole. One end of the centering rod passes through the second positioning hole and the centering rod is suitable for insertion into the cavity of the moving contact.

[0007] In one possible implementation, a centering sleeve is also included; the centering sleeve is fixedly mounted on the first positioning plate, and the side of the centering sleeve facing the first positioning plate extends into the first positioning hole.

[0008] In one possible implementation, both the centering sleeve and the centering rod are made of nylon.

[0009] In one possible implementation, a first preset angle is provided between the first welding plate and the first positioning plate, and a second preset angle is provided between the second welding plate and the second positioning plate.

[0013] Beneficial effects of this application

[0014] This application, through the coordinated action of the first positioning component, the second positioning component, and the centering rod, can accurately fix the position of the moving contact during installation, avoiding deviations in the relative positions of the moving contact and the insulator during installation. This ensures the assembly accuracy of the moving contact and the insulator, thereby improving the overall performance stability of the isolating grounding switch. The accurate assembly accuracy enables the isolating grounding switch to more reliably complete circuit isolation and grounding operations during actual operation. Compared with the prior art that relies solely on manual observation for positioning, this auxiliary positioning device simplifies the installation process of the moving contact, eliminating the need for workers to rely on experience and repeated observation to determine the relative positions of the moving contact and the insulator. This reduces operational difficulty and improves work efficiency. Furthermore, the auxiliary positioning device of this application has a simple structure, can be reused, and has low processing costs.

[0015] By setting up a synchronization plate, the synchronization plate detects the sliding rods of multiple moving contacts and adjusts the relative positions of the sliding rods and moving contacts based on the detection results. This ensures that multiple moving contacts can act synchronously during operation, thereby ensuring that the isolating grounding switch can normally achieve its isolation and grounding functions and guaranteeing the normal operation of the isolating grounding switch.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0035] This application proposes an auxiliary positioning device for installing a moving contact, suitable for providing positioning support for the moving contact 510 when it is fixed to the insulator 530; it includes: a flange 100, a first positioning assembly, a second positioning assembly, and a centering rod 410; the first positioning assembly and the second positioning assembly are disposed opposite to each other on the flange 100; the first positioning assembly includes: two first support rods 210, a first welding plate 220, and a first positioning plate 230; the length directions of the two first support rods 210 are parallel to each other, and the first welding plate 220 is fixedly disposed at the top of the two first support rods 210; The first positioning plate 230 is fixedly disposed on the side of the first welding plate 220 away from the first support rod 210; the first positioning plate 230 is provided with a first positioning hole 231, which is suitable for the sliding rod 520 to pass through the first positioning hole 231 and abut against the first welding plate 220; the second positioning assembly includes two second support rods 310, a second welding plate 320 and a second positioning plate 330; the length directions of the two second support rods 310 are parallel to each other, and the second welding plate 320 is fixedly disposed at the top of the two second support rods 310; the second positioning plate 330 is fixedly disposed on the side of the second welding plate 320 away from the second support rods 310; the second positioning plate 330 is provided with a second positioning hole 331; and the second positioning hole 331 is coaxially disposed with the first positioning hole 231, one end of the centering rod 410 passes through the second positioning hole 331 and the centering rod 410 is suitable for insertion into the cavity of the moving contact 510.

[0036] It should be noted that the first support rod 210 provides stable support for the first welding plate 220 and the first positioning plate 230, fixing them at a certain height so that the first positioning plate 230 can be positioned appropriately to pre-position the moving contact 510. The first welding plate 220 is fixedly mounted on the top of the two first support rods 210, and the length direction of the first welding plate 220 is perpendicular to the length direction of the first support rods 210. The first welding plate 220 provides a stable mounting base for the first positioning plate 230, ensuring the positional accuracy of the first positioning plate 230. The first positioning plate 230 has a first positioning hole 231, which matches the outer contour of the sliding rod 520. When installing the moving contact 510, the sliding rod 520 on the moving contact 510 passes through the first positioning hole 231 and abuts against the first welding plate 220, thereby positioning one end of the sliding rod 520. The first positioning component limits the sliding rod 520 to prevent displacement of the moving contact 510. The second support rod 310 is used to fix the second welding plate 320 and the second positioning plate 330 at a certain height, so that the second positioning plate 330 is in a position corresponding to the first positioning plate 230, and together they position the moving contact 510. The second positioning hole 331 cooperates with the first positioning hole 231 to position the moving contact 510 from two opposite directions, thereby ensuring the axial alignment of the moving contact 510, so that the moving contact 510 can be assembled along the accurate axial direction during installation; improving the accuracy and reliability of positioning. When the centering rod 410 is inserted into the cavity of the moving contact 510, the position of the moving contact 510 can be further accurately determined, ensuring the axial accuracy of the connection between the moving contact 510 and the insulator 530, thereby improving the assembly accuracy of the moving contact 510 and the insulator 530.

[0037] When assembling the moving contact 510 of the isolating grounding switch with the insulator 530, the flange 100 is installed on the insulator 530 and fixed by tightening the conical nut 540. The sliding rod 520 inside the moving contact 510 is rocked toward the first positioning assembly so that the end of the sliding rod 520 away from the contact head passes through the first positioning hole 231 on the first positioning plate 230 and abuts against the first welding plate 220, thereby achieving the pre-positioning of the moving contact 510. One end of the centering rod 410 passes through the second positioning hole 331 on the second positioning plate 330 and is inserted into the cavity of the moving contact 510. The two ends of the moving contact 510 work together with the sliding rod 520 and the centering rod 410 to achieve accurate positioning of the moving contact 510 in the axial direction, ensuring that the sliding rod 520, the moving contact 510 and the centering rod 410 are in a centered state when fixed. At this time, the moving contact 510 and the insulator 530 can be fixed by tightening the spline.

[0038] This application, through the synergistic action of the first positioning component, the second positioning component, and the centering rod 410, can accurately fix the position of the moving contact 510 during installation, avoiding deviations in the relative positions of the moving contact 510 and the insulator 530 during installation. This ensures the assembly accuracy of the moving contact 510 and the insulator 530, thereby improving the overall performance stability of the isolating grounding switch. The accurate assembly accuracy enables the isolating grounding switch to more reliably complete circuit isolation and grounding operations during actual operation. Compared with the prior art that relies solely on manual observation for positioning, this auxiliary positioning device simplifies the installation process of the moving contact 510, eliminating the need for workers to rely on experience and repeated observation to determine the relative positions of the moving contact 510 and the insulator 530. This reduces operational difficulty and improves work efficiency. Furthermore, the auxiliary positioning device of this application has a simple structure, can be reused, and has low processing costs.

[0039] Furthermore, flange 100, the first positioning group, and the second positioning assembly are all made of aluminum alloy, which is lightweight, corrosion-resistant, and easy to process.

[0040] In one possible implementation, the centering rod 410 is made of nylon material. The elastic properties of nylon material allow the centering rod 410 to adapt to the shape and size of the moving contact 510, thereby ensuring that the centering rod 410 can be smoothly inserted into the cavity of the moving contact 510. This not only greatly reduces the difficulty of installation, but also the nylon centering rod 410 can effectively reduce the impact or scratches on the moving contact 510 during the insertion process, thus ensuring the integrity and functionality of the moving contact 510.

[0041] In one possible implementation, there are two or more first positioning holes 231; these two or more first positioning holes 231 are equidistantly arranged along the length of the first positioning plate 230. It should be noted that the lengths of the first positioning plate 230 and the second positioning plate 330 are the same, and correspondingly, there are two or more second positioning holes 331. These two or more second positioning holes 331 are equidistantly arranged along the length of the second positioning plate 330, and the corresponding first positioning holes 231 and second positioning holes 331 are coaxially arranged. The two or more coaxially arranged first positioning holes 231 and second positioning holes 331 can simultaneously perform positioning operations on multiple moving contacts 510, further improving work efficiency. At the same time, the equidistant and coaxial design ensures that the relative position and installation accuracy of each moving contact 510 and the insulator 530 remain highly consistent, ensuring that multiple moving contacts 510 are all on the same plane. This ensures the performance consistency among the moving contacts 510 of the isolating grounding switch and avoids performance instability of the isolating grounding switch due to differences in the installation position of the moving contacts 510.

[0042] In one possible implementation, a centering sleeve 420 is also included; the centering sleeve 420 is fixedly mounted on the first positioning plate 230, and the side of the centering sleeve 420 facing the first positioning plate 230 extends into the first positioning hole 231.

[0043] It should be noted that the centering sleeve 420 is inserted into the first positioning hole 231, and its inner diameter can be adapted to the sliding rod 520. When the sliding contact 510 passes through the first positioning hole 231, the centering sleeve 420 can limit the sliding rod 520 from all sides, which greatly improves the coaxiality between the sliding rod 520 and the first positioning hole 231, prevents it from shifting during the positioning process, and makes the positioning of the sliding rod 520 more accurate.

[0044] Furthermore, the centering sleeve 420 includes an anti-collision part 422 and a fixing part 421. The anti-collision part 422 is arranged in the first positioning hole 231, and one side of the anti-collision part 422 is connected to the fixing part 421. The main body of the fixing part 421 is in a ring shape. The fixing part 421 has a mounting hole. The bolt passes through the mounting hole on the fixing part 421 and connects to the first positioning plate 230, thereby fixing the centering sleeve 420 in the positioning hole of the first positioning plate 230.

[0045] Furthermore, the second positioning plate 330 is provided with a centering sleeve 420, and the second positioning plate 330 and the centering sleeve 420 of the first positioning plate 230 are set in the same way and have the same function, as described in detail above, and will not be repeated here.

[0046] In one possible implementation, the middle sleeve 420 is made of nylon material with a certain degree of elasticity and wear resistance, thereby avoiding rigid contact between the sliding rod 520 and the first positioning hole 231 and preventing wear between the sliding rod 520 and the first positioning plate 230.

[0047] In one possible implementation, a first preset angle is provided between the first welding plate 220 and the first positioning plate 230, and a second preset angle is provided between the second welding plate 320 and the second positioning plate 330. It should be noted that the first preset angle is set according to the actual angle required when the moving contact 510 of the isolating grounding switch is connected to the insulator 530. By setting the first and second preset angles, the tilt angles of the first positioning plate 230 and the second positioning plate 330 can be matched with the installation angle of the moving contact 510, ensuring that the moving contact 510 can be fixedly installed with the insulator 530 at the correct angle.

[0048] In one possible implementation, a synchronizing plate 430 is also included; the synchronizing plate 430 is detachably mounted on the second positioning plate 330. It should be noted that after the moving contact 510 and the insulator 530 are aligned and fixed, the centering rod 410 is pulled out and the synchronizing plate 430 is installed on the side of the second positioning plate 330 opposite to the first positioning plate 230. The synchronizing plate 430 is used to detect whether the sliding rods 520 of multiple moving contacts 510 are coplanar. The synchronizing plate 430 detects the sliding rods 520 of multiple moving contacts 510 and adjusts the relative position of the sliding rods 520 and the moving contacts 510 based on the detection results, ensuring that multiple moving contacts 510 can act synchronously during operation, thereby ensuring that the isolating grounding switch can normally achieve its isolation and grounding functions, and guaranteeing the normal operation of the isolating grounding switch.

[0049] In one possible implementation, the synchronization plate 430 includes a calibration plate 431, a connecting seat 432, and bolts; the connecting seat 432 is fixedly disposed on the side of the calibration plate 431 facing the second positioning plate 330, and the bolts pass through the calibration plate 431 and the connecting seat 432 in sequence to connect with the second positioning plate 330.

[0050] It should be noted that the calibration plate 431 is used to provide a reference plane for detecting the sliding rods 520 of multiple moving contacts 510, and to provide a basis for adjusting the position of the sliding rods 520 and the moving contacts 510. The connecting seat 432 is used to connect the calibration plate 431 and the second positioning plate 330. At the same time, the connecting seat 432 separates the calibration plate 431 and the second positioning plate 330 by a certain distance, so that the operator can observe the contact between each sliding rod 520 and the calibration plate 431, ensuring that the sliding rods 520 of multiple moving contacts 510 are in a synchronous state. The bolts pass through the calibration plate 431, the connecting seat 432 and the second positioning plate 330 in sequence. The preload generated by tightening the bolts makes the calibration plate 431 and the connecting seat 432 firmly fixed on the second positioning plate 330, preventing the synchronization plate 430 from loosening during use. The synchronization plate 430 can be disassembled by turning the bolts in the opposite direction.

[0051] After the moving contact 510 and the insulator 530 are aligned and fixed, the centering rod 410 is pulled out and the synchronizing plate 430 is installed on the side of the second positioning plate 330 away from the first positioning plate 230. The isolation grounding switch is turned on so that two or more sliding rods 520 move synchronously toward the second positioning plate 330. When multiple sliding rods 520 pass through the second positioning hole 331 of the second positioning plate 330 and come into contact with the calibration plate 431, the plane of the calibration plate 431 is used as the reference plane. If multiple sliding rods 520 are in contact with the plane of the calibration plate 431, it can be determined that the sliding rods 520 of multiple moving contacts 510 are in a coplanar state. Otherwise, the relative position of the sliding rods 520 and the moving contact 510 is adjusted and tested until the sliding rods 520 of multiple moving contacts 510 are in a coplanar state.
