Description

Technical Field

[0001] The utility model relates to the technical field of tension strings, in particular to a tension string with an ice-covering-reducing structure. Background Art

[0002] Strain strings, also known as strain insulator strings, are important components in the process of erecting transmission lines. They mainly include two types: ceramic strain insulator strings and composite strain insulator strings. They can effectively isolate live conductors from the ground and keep each wire in its respective position. Strain strings play a key role in the operation and maintenance of transmission lines because they can withstand the influence of various factors, including high voltage of current and changes in the natural environment. An existing patent is for an anti-icing and line-breaking strain string. Patent publication number CN201920363868.6 includes a first U-shaped hanging ring with one end connected to the crossarm and the other end connected to one end of a spring device. The other end of the spring device is connected to a second U-shaped hanging ring. The other end of the second U-shaped hanging ring is connected to a first connecting plate. One end of the ball head hanging ring is connected to the first right-angle hanging plate, and the other end is connected to the end of the insulator. The other end of the sub is connected to the bowl head hanging plate, the bowl head hanging plate is connected to the second connecting plate, the second connecting plate is connected to the second right-angle hanging plate, the second right-angle hanging plate is connected to the adjustment plate, one end of the adjustment plate is connected to the second right-angle hanging plate, and the other end is connected to the third U-shaped hanging ring, and the third U-shaped hanging ring is connected to the tension wire clamp of the fixed conductor to form an anti-icing and wire break tension string. The utility model arranges a spring device, and when the ice tension of the conductor increases, the spring is stretched to prevent the conductor from being broken due to excessive tension. The whole device has a simple structure and can meet the requirements of anti-icing and wire breakage.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although the springs can be used to resist stretching during use, fatigue is prone to occur when the springs are used alone for connection due to the lack of effective rigid connection. When the springs break, the tension string will also break. This has limitations, so we proposed a tension string with an ice-reducing structure to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a tension string with an ice-reducing structure, which solves the problem that the existing technology lacks an effective rigid connection and is prone to fatigue when simply using springs for connection, resulting in the tension string breaking when the spring breaks, which has limitations.

Beneficial Effects
