[0002] With the continuous development of my country's economy, the demand for electricity continues to increase, which in turn leads to the interconnection of power grids, the continuous increase of near-load center sources, the increasing capacity of single machines and generators, etc., making the short-circuit current problem of power grids at all levels of voltage in the power system increasingly serious. Coupling capacitors are mainly used in industrial frequency high-voltage and ultra-high-voltage AC transmission lines to achieve the purposes of carrier, communication, measurement, control, protection and extraction of electric energy. Coupling capacitors can solve problems such as excessive short-circuit current in the power grid.

[0003] At present, when connecting a coupling capacitor, the connection is made by docking the wiring harness and the joint of the coupling capacitor, and the two sides of the lower end of the coupler are directly limited and fixed by blocks. Coupling capacitors are mostly used outdoors. Due to the outdoor use environment, the coupling capacitor has poor stability during use. When encountering strong winds or impact, the bottom of the coupling capacitor is easily loosened, resulting in low installation stability of the coupling capacitor.

[0004] Therefore, we propose a coupling capacitor structure to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-3 A coupling capacitor structure includes a coupling capacitor body 1 and a connecting component 2 arranged at the upper end of the coupling capacitor body 1, a docking component 3 is fixedly installed at the lower end of the coupling capacitor body 1, and mounting components 4 are movably installed at the four corners of the upper end of the docking component 3. The setting of the docking component 3 is used to assist the coupling capacitor body 1 in fixed installation. The docking component 3 includes a first docking mechanism 31 and a fixing mechanism 32 movably installed in the inner cavity of one end of the first docking mechanism 31, and a second docking mechanism 33 is movably installed at one end of the fixing mechanism 32. The first docking mechanism 31, the fixing mechanism 32 and the second docking mechanism 33 are set to fix the lower end of the coupling capacitor body 1.

[0025] The first docking mechanism 31 includes a U-shaped bottom plate 311 and a through groove 312 provided in the middle of both sides of the upper end of the U-shaped bottom plate 311. An insulating rubber layer 313 is embedded in the inner wall of the U-shaped bottom plate 311 to improve the safety of the installation of the U-shaped bottom plate 311.

[0026] The fixing mechanism 32 includes a right-angle block 321 and a threaded rod 322 fixedly installed on one side of the upper end of the right-angle block 321. An elastic element 323 is fixedly installed on one end of the outer wall of the right-angle block 321, and a round clamping ball 324 is fixedly installed on one end of the elastic element 323. The right-angle block 321 drives the threaded rod 322 to be movably installed in the inner cavity of the penetration groove 312, and the threaded rod 322 is threadedly fixedly installed on one side of the notch of the penetration groove 312 through a nut.

[0027] The second docking mechanism 33 includes a corresponding U-shaped block 331 and an embedding groove 332 opened at both ends of one side of the corresponding U-shaped block 331. A circular groove 333 is opened on one side of the inner wall of the embedding groove 332. The other end of the right-angle block 321 is movably installed in the inner cavity of the embedding groove 332. The round card ball 324 is automatically inserted into the inner cavity of the circular groove 333 under the elastic force of the elastic element 323.

[0028] In this embodiment: when installing the coupling capacitor, the operator can first use the U-shaped bottom plate 311 and the corresponding U-shaped block 331 to wrap the lower end of the coupling capacitor, and then push the right-angle blocks 321 movably installed on both sides of the U-shaped bottom plate 311 into the inner cavity of the embedding groove 332, so that the right-angle blocks 321 drive the elastic element 323 and the round card ball 324 to be inserted into the inner cavity of the embedding groove 332, and the round card ball 324 will automatically be embedded in the inner cavity of the circular groove 333 for fixation after encountering the circular groove 333 under the elastic force of the elastic element 323. The operator uses a nut to thread the threaded rod 322 to the upper end of the notch of the penetration groove 312, thereby completing the fixation of the lower end of the coupling capacitor, and then fixes the U-shaped bottom plate 311 and the corresponding U-shaped block 331 to the position where they need to be fixed by screws, thereby improving the stability of the installation of the bottom of the coupling capacitor.

[0029] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 4-5 Square grooves 314 are respectively formed on both sides of the upper end of the U-shaped bottom plate 311 , and insertion grooves 315 are formed around the inner wall of the square groove 314 .

[0030] The mounting assembly 4 includes a hollow ring 41 and an insertion rod 42 fixedly mounted around the outer wall of the hollow ring 41 . The hollow ring 41 drives the insertion rod 42 to be movably mounted in the inner cavity of the square groove 314 . The insertion rod 42 is movably mounted in the inner cavity of the insertion groove 315 .

[0031] In this embodiment: the operator determines the fixed position of the coupling capacitor, opens a threaded groove at the position to be fixed in advance, places the docking component 3 on its upper end, and according to the position of the threaded groove opened at the fixed position, passes the screw through the hollow ring 41 to drive the hollow ring 41 to move in the inner cavity of the square groove 314. By setting the hollow ring 41 to drive the screw to move, the screw can accurately drive the hollow ring 41 and the fixed position to be threadedly fixed, thereby reducing the problem of the notch opened at the upper end of the U-shaped bottom plate 311 not corresponding to the notch opened at the fixed position.

[0032] Working principle: The operator uses the U-shaped bottom plate 311 and the corresponding U-shaped block 331 to wrap the lower end of the coupling capacitor, and then pushes the right-angle blocks 321 movably installed on both sides of the U-shaped bottom plate 311 into the inner cavity of the embedding groove 332, so that the right-angle blocks 321 drive the elastic element 323 and the round card ball 324 to be inserted into the inner cavity of the embedding groove 332, and the round card ball 324 will automatically be embedded in the inner cavity of the round groove 333 under the elastic force of the elastic element 323 after encountering the round groove 333 for fixing. The threaded rod 322 is threadedly fixedly installed on the upper end of the notch of the penetration groove 312 with a nut to complete the fixation of the lower end of the coupling capacitor. After determining the fixing position of the coupling capacitor, a threaded groove is opened in advance at the position to be fixed. According to the position of the threaded groove opened at the fixed position, the screw is passed through the hollow ring 41 to drive the hollow ring 41 to move in the inner cavity of the square groove 314. By setting the hollow ring 41 to drive the screw to move, the screw can accurately drive the hollow ring 41 and the fixed position to be threadedly fixed.
