Description

Technical Field

[0001] This utility model relates to the field of line protection technology, and in particular to a quick-installation equalizing ring for lines. Background Technology

[0002] A voltage equalizing ring is a ring-shaped conductive fitting used in power lines to improve the voltage distribution at insulator strings or cable terminals. As an additional conductor, it guides the electric field lines around high-voltage power lines, making their distribution more uniform and reducing the potential difference across the insulators. For example, on high-voltage transmission lines, especially in areas with long insulator strings or high electric field strength, uneven electric field distribution can increase the voltage difference across the insulators. A voltage equalizing ring can change the electric field distribution, making the voltage more uniform.

[0003] The existing equalizing ring installation requires a power outage. If the installation is slow, the power outage time will be extended, which will also affect the overall construction progress and make it impossible to complete the construction or maintenance of the line on time. This may affect the normal power supply, cause inconvenience to production and life, and may even cause system failure, leading to an expansion of the power outage area and affecting the reliability and stability of the power system.

[0004] Therefore, since the existing equipotential ring installation requires a power outage, slow installation will prolong the power outage time, affect the construction progress, and may even cause system failures, affecting the reliability and stability of the power system. A quick-installation equipotential ring for the line can be designed, using a connection structure to quickly adapt and install the equipotential ring. Utility Model Content

[0005] To overcome the problem that the existing equalizing ring installation needs to be carried out under power outage conditions, if the installation speed is slow, the power outage time will be extended, affecting the construction progress, and may even cause system failure, affecting the reliability and stability of the power system.

[0006] The technical solution of this utility model is as follows: a quick-installation equalizing ring for a line, comprising a mounting plate, support rods, and a ring body; four sets of support rods are mounted around the outside of the mounting plate, the support rods are set at an angle, a ring body is provided below the mounting plate and fixedly connected to the support rods, four sets of mounting holes are opened around the mounting plate, and mounting screws are inserted through the center of the mounting holes.

[0007] Preferably, the mounting circular plate is first quickly fixed to the required position, and then, depending on the thickness of the plate, it is further reinforced by adjusting and limiting the extension and retraction through the arc-shaped telescopic sleeve and arc-shaped telescopic plate on the inner side of the ring.

[0008] Preferably, four sets of arc-shaped telescopic sleeves are arranged around the inner side of the ring, and an arc-shaped telescopic plate is sleeved and connected between each two sets of arc-shaped telescopic sleeves.

[0009] Preferably, a positioning pin is provided at the connection between the arc-shaped telescopic plate and the arc-shaped telescopic sleeve, and multiple sets of positioning holes are opened along the edge of the arc-shaped telescopic plate.

[0010] Preferably, the positioning pin passes through the arc-shaped telescopic sleeve and is positioned and connected to the arc-shaped telescopic plate through the positioning hole.

[0011] Preferably, a rectangular telescopic plate is installed on the middle of the outer side of the arc-shaped telescopic sleeve, and a rectangular telescopic sleeve that is fixedly connected to the ring body is fitted on the outside of the rectangular telescopic plate.

[0012] Preferably, fixing pins are symmetrically provided on both sides of the connection between the rectangular telescopic sleeve and the rectangular telescopic plate, and multiple sets of fixing holes are symmetrically opened on both sides of the rectangular telescopic plate.

[0013] Preferably, the fixing pin passes through the rectangular telescopic sleeve and is positioned and connected to the rectangular telescopic plate through the fixing hole.

[0014] The beneficial effects of this utility model are as follows: First, the mounting circular plate is quickly fixed to the required position. Then, according to the thickness of the plate at the position, the arc-shaped telescopic sleeve and arc-shaped telescopic plate on the inner side of the ring are used for telescopic adjustment and limiting, which further strengthens the installation. This method greatly reduces the operation steps and time required during installation, effectively improves the efficiency of line construction and maintenance, speeds up the overall construction progress, shortens the project cycle, and enables the line to be put into use or restored to operation more quickly, reducing the impact on power supply. It can also ensure the safe operation of the line in a high-voltage environment and improve the stability and reliability of the power system. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a quick-installation equalizing ring for a circuit, comprising a mounting circular plate 1, support rods 2, and a ring body 3; four sets of support rods 2 are mounted around the outside of the mounting circular plate 1, the support rods 2 are arranged at an angle, and a ring body 3 is provided below the mounting circular plate 1 to be fixedly connected to the support rods 2; four sets of mounting holes 101 are opened around the mounting circular plate 1, and mounting screws 102 are inserted through the middle of the mounting holes 101.

[0022] Please see Figures 3-4 In this embodiment, four sets of arc-shaped telescopic sleeves 301 are arranged around the inner side of the ring body 3. An arc-shaped telescopic plate 302 is sleeved and connected between every two sets of arc-shaped telescopic sleeves 301. By adjusting the positioning pin 303, the arc-shaped telescopic plate 302 retracts and adjusts along the arc-shaped telescopic sleeve 301 until the inner wall of the arc-shaped telescopic sleeve 301 is close to its position. A positioning pin 303 is provided at the connection between the arc-shaped telescopic plate 302 and the arc-shaped telescopic sleeve 301. Multiple sets of positioning holes 304 are opened along the edge of the arc-shaped telescopic plate 302. The positioning pin 303 passes through the positioning hole 304 to fix the adjustment of the arc-shaped telescopic sleeve 301 and the arc-shaped telescopic plate 302. The positioning pin 303 passes through the arc-shaped telescopic sleeve 301 and is positioned and connected to the arc-shaped telescopic plate 302 through the positioning hole 304. Pick up the positioning pin 303, pass it through the arc-shaped telescopic sleeve 301 and position it to the arc-shaped telescopic plate 302 through the positioning hole 304. A rectangular telescopic plate 305 is installed on the middle of the outer side of the arc-shaped telescopic sleeve 301. A rectangular telescopic sleeve 306, which is fixedly connected to the ring body 3, is fitted on the outside of the rectangular telescopic plate 305. By adjusting the fixing pin 307, the rectangular telescopic plate 305 drives the arc-shaped telescopic sleeve 301 to move along the rectangular telescopic sleeve 306. Fixing pins 307 are symmetrically arranged on both sides of the connection between the rectangular telescopic sleeve 306 and the rectangular telescopic plate 305. Multiple sets of fixing holes 308 are symmetrically opened on both sides of the rectangular telescopic plate 305. The fixing pins 307 pass through the fixing holes 308 to fix the adjustment of the rectangular telescopic sleeve 306 and the rectangular telescopic plate 305. The fixing pins 307 pass through the rectangular telescopic sleeve 306 and are positioned and connected to the rectangular telescopic plate 305 through the fixing holes 308. The fixing pins 307 are picked up and passed through the rectangular telescopic sleeve 306 and are positioned and connected to the rectangular telescopic plate 305 through the fixing holes 308.

[0023] During operation, first, pass the ring 3 through the desired installation position, then place the mounting plate 1 in the position. If the mounting screw 102 is removed, pass it through the mounting hole 101 to fix the mounting plate 1 in place. Then, depending on the thickness of the position, adjust the fixing pin 307 and the positioning pin 303. The rectangular telescopic plate 305 drives the arc telescopic sleeve 301 to move along the rectangular telescopic sleeve 306. At the same time, the arc telescopic plate 302 retracts along the arc telescopic sleeve 301 until the inner wall of the arc telescopic sleeve 301 is close to the position, limiting and reinforcing it. After confirming that everything is correct, remove the fixing pin 307, pass it through the rectangular telescopic sleeve 306 and fix it to the rectangular telescopic plate 305 through the fixing hole 308. Then remove the positioning pin 303, pass it through the arc telescopic sleeve 301 and fix it to the arc telescopic plate 302 through the positioning hole 304. After all the assembly is completed, it can be used. During this process, the support rod 2 can support and fix the ring 3.

[0024] Through the above steps, the installation circular plate 1 is first quickly fixed to the required position. Then, according to its thickness, the arc-shaped telescopic sleeve 301 and arc-shaped telescopic plate 302 on the inner side of the ring body 3 are used for telescopic adjustment and limiting, and further reinforcement is carried out. This method greatly reduces the operation steps and time required during the installation process, effectively improves the efficiency of line construction and maintenance, speeds up the overall construction progress, shortens the project cycle, and enables the line to be put into use or restored to operation more quickly, reducing the impact on power supply. It can also ensure the safe operation of the line in a high-voltage environment, improve the stability and reliability of the power system, and solve the problem that the installation of the existing equalizing ring needs to be carried out under power outage conditions. If the installation speed is slow, the power outage time will be prolonged, affecting the construction progress, and may even cause system failure, affecting the reliability and stability of the power system.
