Description

Technical Field

[0001] The present invention relates to the field of power transmission line accessories, and more particularly to an anti-dancing spacing device and method for split conductors of power transmission lines. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. However, the intervals between line towers are usually large, because the transmission lines between towers are prone to dancing under the influence of wind, which can easily cause corona discharge and other situations.

[0003] Split conductor refers to a method of laying conductors for ultra-high voltage transmission lines to suppress corona discharge and reduce line reactance. The number of split conductors of ordinary split conductors generally does not exceed 4, and the number of split conductors of ultra-high voltage transmission lines is generally 3 to 4. Therefore, in the prior art, a conductor rack is usually used to support and stabilize the position of the transmission line. However, the conductor rack in the prior art is usually an integrated fixed structure, and the support width of the conductor rack cannot be adjusted as needed. Therefore, when the two conductor racks are far apart, it is still easy for the split conductors to contact each other. Moreover, during replacement and maintenance, when the conductor rack is removed, it is still easy for the split conductors to contact each other, thereby posing a threat to the safety of the staff.

[0004] In the prior art, a single spacer bar is often used to connect multiple split conductors to maintain the distance between the conductors at a fixed distance, thereby preventing the conductors from being deflected by the wind. However, when the amplitude is large, a single spacer bar often cannot provide a good wind protection effect, and the spacer bar will shake with the overall deviation of the multiple split conductors.

[0005] Moreover, when the spacing of the four-split conductors is fixed, a spacer with a non-adjustable wire clamp position is generally used. At the same time, in order to slow down the wind polarization, consume vibration energy, and use inertial force to achieve vibration elimination, a shockproof pendulum structure is generally set. According to different installation scenarios, the position, specifications, weight and angle of the pendulum are fixed, which is adapted to the installation environment and cannot be adjusted. However, when the wire spacing needs to be adjusted, the adjustable spacer is often not suitable for matching the shockproof pendulum, and naturally its anti-dancing performance cannot achieve a good effect. Prior art document 1 (CN107591763B) discloses a transmission line conductor shock-absorbing and anti-dancing phase spacer, comprising a composite insulator and a sub-conductor spacer movably connected to both ends of the composite insulator through hardware, which solves the problem of stress concentration at the outlet of the fixed damping wire clamp and reduces the wear on the wire and the wire clamp. However, the technical starting point of this technical document is that it is used in the scenario of two groups of four split conductors in the upper and lower parts, and the adjustable phase spacing is achieved through an adjustable connection mechanism, which plays a role in integrating the two groups of split conductors during dancing, thereby buffering the torque. It also cannot play the role of combining with a pendulum to consume the swinging inertia force of the wire segment provided with the spacer. Summary of the invention

[0006] In order to solve the deficiencies in the prior art, the present invention provides an anti-dancing spacing device for split conductors of power transmission lines, which is used to solve the problem of how to combine the anti-dancing performance of the pendulum to achieve the best anti-dancing effect in an installation environment where multiple split conductors have different spacings.

[0017] The second aspect of the present invention discloses a method for preventing galloping of split conductors of a power transmission line, based on the anti-galloping spacing device for split conductors of a power transmission line, comprising the following steps: Place the spacer between the multiple wires and place the wires inside the support, so that the support can stabilize the top cover through the connection assembly to prevent the wires from falling off; Connect multiple conductors to the support in sequence to complete the installation of the spacer bars; The distance between the support and the base frame is adjusted by the adjustment mechanism to avoid dancing contact caused by the base frame being too far away; A plurality of spacer bars with the same structure are arranged in parallel and connected through a connecting assembly to form an overall anti-galloping combined structure, thereby realizing the anti-galloping of the split conductors of the power transmission line.

[0018] The beneficial effect of the present invention is that, compared with the prior art, (1) When support for split conductors is required, the present scheme places the base frame between the multiple conductors and places the conductors inside the support.

The multiple conductors can be fixed in sequence to separate the multiple conductors to prevent them from dancing. The distance between the support and the base frame can be adjusted by adjusting the distance mechanism as needed to adjust the distance between the conductors. This can prevent the conductors from dancing and contacting due to the distance between the base frames being too far. When replacing the spacing device, the spacing devices at both ends of the base frame to be replaced can be adjusted to increase the spacing between the conductors. This can prevent the conductors from dancing and contacting when the base frame is replaced, thereby ensuring the safety of the workers.

[0019] (2) By rotating the screw rod and stabilizing the position of the screw rod in the through slot by the positioning assembly, and stabilizing the position of the support rod in the rod slot by the limit assembly, the support rod is prevented from rotating with the screw rod. The screw rod can drive the support rod to slide in the rod slot through the threaded groove, so that the support rod can drive the support platform to move at the same time, so that the adjustment mechanism can adjust the distance between the support platform and the base frame, and then adjust the wire spacing, avoiding the corona discharge caused by the dancing contact of the wires.

[0020] (3) By arranging two groups of spacer bars in parallel, the segmented conductor can resist greater wind force better than a single spacer bar. At the same time, since the two groups of spacer bars are fixedly connected by a connecting assembly, the segmented conductor can withstand greater twisting force, greatly enhancing the wind resistance level. By arranging a pendulum structure that can maintain buffering and self-balancing, it can be ensured that the overall structure of the spacer device has an excellent effect of consuming vibration energy when the wind deflects and dances, so that the overall solution of the present invention has a strong level of adaptability to different scenarios and comprehensive anti-dance ability.

[0035] Embodiment 2 of the present invention provides a method for preventing galloping of split conductors of a power transmission line, based on the anti-galloping spacing device for split conductors of a power transmission line, comprising the following steps: Place the spacer rods between the multiple wires, and place the wires inside the support 3, so that the support 3 can stabilize the position of the top cover 4 through the connecting assembly 5 to prevent the wires from falling off; Connect multiple wires to the support 3 in sequence to complete the installation of the base frame 1; The distance between the support 3 and the base frame 1 is adjusted by the adjustment mechanism 2 to avoid the base frame 1 being too far away and causing dancing contact; A plurality of spacer bars with the same structure are arranged in parallel and connected through the connecting assembly 6 to form an overall anti-dancing combined structure, thereby achieving anti-dancing of the split conductors of the power transmission line.

[0036] The working process of the embodiment of the present invention is described in detail below: When a single spacer rod is used to support the split conductor, the base frame 1 is placed between the multiple conductors, and the conductors are placed inside the support platform 3. Then, the top cover 4 is rotated inside the mounting frame 311 by the rotating rod 312, so that the top cover 4 can close the support platform 3 through the rotating component 31, and at the same time, the connecting block 51 is inserted into the inside of the connecting frame 52. Then, one end of the bolt 531 passes through the connecting frame 52 and the connecting block 51, and the nut 532 is threadedly connected to the outer wall of one end of the bolt 531, so that the front side of the nut 532 fits with the back side of the connecting frame 52, and the connecting block 51 can be fixed inside the connecting frame 52 by the fixing component 53, so that the support platform 3 can fix the position of the top cover 4 through the connecting component 5 to prevent the conductor from falling off. Then, the conductors are connected to the support platform 3 in sequence to complete the installation of the base frame 1, thereby achieving the effect of separating the multiple conductors. Then, as needed, the distance between the support platform 3 and the base frame 1 is adjusted through the adjustment mechanism 2, the screw rod 242 is rotated, and the positioning block 251 is rotated to be connected to the inside of the positioning groove 252, so that the positioning assembly 25 stabilizes the position of the screw rod 242 in the through groove 241, and the limiting block 231 is slidably connected to the inside of the limiting groove 232, so that the limiting assembly 23 stabilizes the position of the support rod 22 in the rod groove 21, and prevents the support rod 22 from rotating with the screw rod 242, that is, the screw 242 can drive the support rod 22 to slide in the inside of the rod groove 21 through the thread groove 243, so that the control assembly 24 can adjust the position of the support platform 3 through the support rod 22, so that the adjustment mechanism 2 can adjust the distance between the support platform 3 and the base frame 1, and then adjust the distance between the wires, and avoid the situation where the base frame 1 is too far away and the wires are in dancing contact; When replacing the spacer, the spacers at both ends of the base frame 1 to be replaced are adjusted to increase the interval between the wires, so that the wires can be prevented from dancing and contacting when the base frame 1 is replaced. Two spacers with the same structure are arranged in parallel and connected by a connecting assembly to form an overall anti-dancing combined structure. The pendulum structure inside the connecting assembly is buffered and self-balanced by springs and air bags, which is conducive to the contraction of inertial force and amplitude during dancing, so as to greatly reduce vibration energy.

[0037] It is worth noting that by setting two spliced ​​spacer bars on a certain section of the conductor, on the one hand, the combined spacer bars can be used as an overall anti-dance mechanism to achieve anti-dance, and on the other hand, a pendulum structure that can be fine-tuned by a spring can be set at the second connecting component of the overall structure to achieve the anti-inertia force of the pendulum.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
