Description

Technical Field

[0001] The invention belongs to the technical field of overhead power transmission lines, and in particular relates to a live working triangular spacer for a 10 kV line. Background Art

[0002] In recent years, with the rapid development of social economy and the continuous improvement of people's living standards, power users have increasingly higher requirements for power supply reliability. The stability and safety of power supply are directly related to the normal operation of social production and life, especially under extreme weather conditions such as strong winds, hail, rain and snow, the safe operation of power lines faces severe challenges. Among them, 10 kV lines are an important part of the distribution network, and their operating status directly affects the power consumption experience of the majority of users.

[0003] In severe weather conditions, 10kV lines are extremely susceptible to ice. Ice on the conductors not only increases the weight of the conductors, resulting in an increase in gravity load and a larger arc of suspension, but also increases the surface area of ​​the conductors, significantly increasing wind loads and causing the conductors to dance. This dancing not only shortens the safe distance between line phases, but can also lead to phase-to-phase flashover, broken strands, and severe wear of lines and fittings, ultimately causing serious consequences such as phase-to-phase short circuits, phase-to-ground short circuits, relay protection action, and line tripping, and even catastrophic accidents such as line breakage and tower collapse.

[0004] To address this problem, existing technical means mainly focus on strengthening line inspections, improving line design standards, and adopting automated monitoring equipment. However, these measures still have problems such as slow response and limited prevention effects when dealing with sudden and extreme weather line failures. Especially in live working environments, how to effectively prevent line sway and phase-to-phase short circuits while ensuring the safety of workers has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a triangular spacer for live working on a 10 kV line to solve the above-mentioned technical problems.

[0006] A triangular spacer for live working on a 10 kV line comprises three insulating rods arranged in a triangle, three fixing assemblies arranged at the corners of the triangle, and a conductor clamp assembly installed at one end of the fixing assembly away from the insulating rods; the insulating rod comprises a core rod and an insulating sleeve sleeved around the core rod, the length of the core rod is greater than the length of the insulating sleeve, both ends of the core rod are fixed inside the fixing assembly, a damping shock absorber is arranged between the core rod and the fixing assembly, a vibration sensor is installed on the insulating sleeve, a microcontroller is also arranged on the fixing assembly, and the damping shock absorber and the vibration sensor are both connected to the microcontroller.

[0007] A further improvement of the present technical solution is that the fixing assembly includes a first metal fixing plate, a second metal fixing plate and a metal connecting plate, the first metal fixing plate and the second metal fixing plate are both vertically mounted on the connecting plate, the first metal fixing plate and the second metal fixing plate are arranged in parallel, two damping shock absorbers arranged at a preset angle are fixed between the first metal fixing plate and the first metal fixing plate, and the output end of the damping shock absorber is connected to the core rod.

[0008] A further improvement of the technical solution is that the surfaces of the first metal fixing plate and the second metal fixing plate are coated with a waterproof layer.

[0009] A further improvement of the technical solution is that the damping shock absorber adopts a damping shock absorber of model HCL-30.

[0010] A further improvement of the technical solution is that the wire clamp assembly includes a mounting seat and a wire clamp mounted on the mounting seat, and one end of the mounting seat away from the wire clamp is fixed to one end of the metal connecting plate away from the core rod.

[0011] A further improvement of the technical solution is that a shock-absorbing gasket is arranged between the mounting seat and the metal connecting plate.

[0012] A further improvement of the technical solution is that a rubber anti-skid pad is fixed on the inner surface of the anti-skid pad wire clamp.

[0013] A further improvement of the technical solution is that an umbrella skirt is fixed on the outer side of each insulating sleeve.

[0014] A further improvement of the technical solution is that the core rod is woven from glass fiber cloth impregnated with alicyclic epoxy resin, and the insulating sleeve is made of epoxy resin.

[0015] A further improvement of the technical solution is that it also includes a communication module, and the microcontroller is connected to a remote monitoring device via the communication module.

[0016] The beneficial effects of the present invention are: Improve power supply reliability and stability: By adopting the design of three insulating rods arranged in a triangle, the overall structural stability of the spacer rods is enhanced, effectively preventing faults such as phase-to-phase short circuits caused by conductor dancing, thereby significantly improving the reliability and stability of power supply and ensuring the normal progress of social production and life.

[0017] Active prevention and real-time response: The vibration sensor installed on the insulating rod can monitor the vibration of the wire in real time. Once abnormal vibration is detected, the signal is immediately transmitted to the microcontroller. The microcontroller analyzes the vibration data and promptly activates the damping shock absorber for shock absorption, thus achieving active prevention and real-time response to wire galloping, effectively preventing the shortening of the phase-to-phase safety distance.

[0018] Enhanced wind and ice resistance: The damping shock absorber design between the core rod and the fixed component effectively absorbs the increased gravity load and wind load of the conductor due to ice covering, reduces the dancing amplitude of the conductor, and enhances the wind and ice resistance of the spacer rod. Even in severe weather conditions, it can ensure the safe and stable operation of the line.

[0019] Improve the safety of live working: This technical solution not only solves the technical problems of line dancing and phase short circuit, but also fully considers the safety requirements of live working. By optimizing the structural design and functional configuration of the spacer, it provides a safer and more reliable working environment for live working personnel and reduces the operating risks.

[0020] Reduce maintenance costs and improve economic benefits: By improving the operational stability and reliability of the line, the number of power outages and maintenance costs caused by faults are reduced. At the same time, the application of this technical solution can also extend the service life of the line and improve the overall economic benefits of the power grid.

[0021] In addition, the invention has a reliable design principle, a simple structure and a very broad application prospect. BRIEF DESCRIPTION OF THE DRAWINGS
