[0001] The utility model relates to the technical field of coupling capacitors, in particular to a coupling capacitor device for testing. Background Technique
[0002] A coupling capacitor is an important device in the high-frequency channel of the power system. It is a capacitor used to transmit signals in the power network and is mainly used in power frequency high-voltage and ultra-high-voltage AC transmission lines to achieve purposes such as carrier, communication, measurement, control, protection, and power extraction. In the initial stage of using the coupling capacitor, personnel usually conduct voltage tests on the coupling capacitor, which consists of a base, a coupler, a flange, a connection socket, etc.
[0003] The above-mentioned and existing related technologies often have the following defects: During the test, generally, wires are inserted into the connection socket of the flange through a connection plate. However, the base coupler is in the test site for a long time. Therefore, during the site test, it is very easy to drag the wires, and the wires will drive the position of the flange through the connection plate. Since the flange and the connection plate are generally connected by bolts, once the wires are dragged and the connection plate is pulled, the bolts are easily squeezed in the flange, resulting in the problem that the bolts are stripped in the connection plate and are not easy to disassemble later.
[0004] Therefore, we propose a coupling capacitor device for testing. Content of the Utility Model

DETAILED DESCRIPTION
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figure 1 , the present utility model provides a technical solution: a coupling capacitor device for experiments, including a base 1. A coupler 2 is installed on the upper surface of the base 1. The arc surface of the base 1 is fixedly connected with an outer box 3. A box door 4 is rotatably connected to one side of the outer box 3 away from the base 1. A flange 5 is fixedly connected to the position of the arc surface of the base 1 relative to the inside of the outer box 3. A connection socket 6 is provided on the inner wall of the flange 5. A positioning structure 7 is provided on the upper surface of the outer box 3, achieving the effect of positioning the connection socket 6 flange 5 of the experimental coupling capacitor, thereby minimizing the problem that the wires at the test site are easily dragged to drive the connection plate, causing the bolts in the flange 5 connected thereto to be extruded and the threads to slip, making it difficult to disassemble. An auxiliary structure 8 is provided on one side of the box door 4, achieving the effect of temporarily limiting the box door 4. After the box door 4 is limited by the cooperation of various components, the box door 4 will no longer swing naturally, thereby avoiding affecting the installation of the flange 5 by personnel and improving the practicability of the device.
[0031] The following specifically describes the specific settings and functions of its positioning structure 7 and auxiliary structure 8.
[0032] As Figure 2 and Figure 3 as well as Figure 4 shown, the positioning structure 7 includes a frame 701. The lower surface of the frame 701 is fixedly connected to the outer box 3. A driving rod 702 is threadedly penetrated through the upper surface of the frame 701. A sliding rod 703 is slidably penetrated through the inner wall of the frame 701. The sliding rod 703 penetrates the outer box 3. The lower end of the driving rod 702 abuts against the sliding rod 703. A positioning frame 704 is fixedly connected to the lower surface of the sliding rod 703. The inner wall of the positioning frame 704 abuts against the flange 5. A bottom plate 705 is fixedly connected to the arc surface of the base 1. The inner wall of the bottom plate 705 abuts against the flange 5. Two side plates 706 are fixedly connected to the inner wall of the bottom plate 705. Elastic ropes 707 are fixedly connected to both sides of the sliding rod 703 on the upper surface of the positioning frame 704. The other ends of the two elastic ropes 707 are fixedly connected to the outer box 3. When the sliding rod 703 is separated from the driving rod 702, the elastic ropes 707 contract, and the elastic ropes 707 play a role in quickly resetting the positioning frame 704.
[0033] The inner wall of the flange 5 is slidably connected with a positioning rod 708. The arc dimension of the positioning rod 708 is adapted to the inner wall dimension of the flange 5. Move the positioning rod 708 to insert it into the inner walls of the connecting plate and the flange 5. The positioning rod 708 achieves the effect of positioning the bolt connection holes between the connecting plate and the flange 5. One end of the positioning rod 708 is fixedly connected with a connecting rope 709. The other end of the connecting rope 709 is fixedly connected with the bottom plate 705. The movement of the positioning rod 708 drives the movement of the connecting rope 709. The connecting rope 709 plays a role in limiting the positioning rod 708 to prevent it from being lost. An inner groove 710 is formed in the inner wall of the bottom plate 705. A damping pad 711 is fixedly connected to the inner wall of the inner groove 710. The connecting plate is in contact with the damping pad 711. The damping pad 711 achieves the effect of improving the self-stability of the connecting plate.
[0034] As Figure 5 shown, the auxiliary structure 8 includes a sliding frame 81. One side of the sliding frame 81 is fixedly connected with the box door 4. A sliding plate 82 is slidably connected to the inner wall of the sliding frame 81. One side of the sliding plate 82 is fixedly connected with a connecting rod 83. The other side of the connecting rod 83 is fixedly connected with an iron plate 84. A magnet 85 is fixedly connected to the upper surface of the box door 4. One side of the magnet 85 is attracted to the iron plate 84. A U-shaped ring 86 is fixedly connected to one side of the box door 4 close to the sliding frame 81. The surface of the sliding plate 82 is slidably connected to the inner wall of the U-shaped ring 86. Move the sliding plate 82 to insert it into the U-shaped ring 86. The U-shaped ring 86 plays a role in supporting the sliding plate 82 so that it no longer contacts the magnet 85, enabling the box door 4 to open and close quickly.
[0035] Working principle: When it is necessary to test the coupling capacitor, first open the box door 4. After limiting the box door 4 through the auxiliary structure 8, drive the wire with the connection plate to move above the bottom plate 705 on one side of the flange plate 5. Then slowly place the connection plate to fit with the damping pad 711. The damping pad 711 achieves the effect of improving the stability of the connection plate itself. At this time, the connection plate fits with the side plate 706, and the wire is inserted into the connection socket 6 through the connection plate. Then move the positioning rod 708 to drive the connection rope 709 to insert into the bolt hole on one side of the connection plate. The connection rope 709 plays a role in limiting and preventing the loss of the positioning rod 708. The positioning rod 708 is inserted into the bolt hole on one side of the flange plate 5 through the connection plate. The positioning rod 708 achieves the effect of positioning the bolt connection hole between the connection plate and the flange plate 5, thereby aligning the bolt holes of the connection plate and the flange plate 5. Then rotate the driving rod 702 through the frame 701 towards the side close to the flange plate 5. The sliding rod 703 slides out of the frame 701 through the driving rod 702 and then slides out of the outer box 3. The positioning frame 704 fits with the flange plate 5 and the connection plate through the sliding rod 703. The elastic rope 707 is in a stretched state at this time due to the movement of the positioning frame 704. The elastic rope 707 plays a role in quickly resetting the positioning frame 704. Finally, insert the bolt into the bolt holes of the connection plate and the flange plate 5 for installation. After pulling out the positioning rod 708, install the remaining bolts. Then transmit the voltage of the wire to the base 1, so as to test whether the strong electricity and weak electricity can be isolated by the coupler 2.
[0036] When it is necessary to limit the box door 4, rotate the box door 4. The sliding plate 82 in the sliding frame 81 drives the connecting rod 83 to rotate through the box door 4. The iron plate 84 rotates through the connecting rod 83 to fit with the magnet 85. The magnet 85 is then attracted to the iron plate 84 by magnetic force, thereby driving the iron plate 84 to drive the sliding plate 82 to be limited through the connecting rod 83. The sliding frame 81 limits the box door 4 rotated by a certain angle through the sliding plate 82. When it is only necessary to open the box door 4 without limiting it, move the sliding plate 82 to disengage from the sliding frame 81 and insert it into the U-shaped ring 86. The U-shaped ring 86 plays a role in supporting the sliding plate 82 so that it no longer contacts the magnet 85, enabling the box door 4 to open and close quickly. When the box door 4 drives the U-shaped ring 86 to rotate, the sliding plate 82 drives the iron plate 84 to fit with the box door 4 through the U-shaped ring 86 and the connecting rod 83, so that the magnet 85 and the iron plate 84 no longer contact.
