Problems solved by technology

[0002] At present, transmission lines have been tripped many times due to floating objects such as reflective film. Usually, the towers of transmission lines are relatively high, and it is difficult for foreign objects to fly directly onto the lines. It reaches the cross-arm insulator, which causes the grounding trip of the transmission line. Because there are many orchards in Yantai area, orchards use reflective film on a large area, and the line trip caused by the reflective film on the transmission and distribution line accounts for nearly 50% of all line faults every year.

specific Embodiment approach

[0009] The specific embodiment: the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

Embodiment

[0010] Embodiment: a kind of barb mechanism of anti-transmission line reflective film (see Figure 1-Figure 3 ), which includes a parallel groove clamp 1, and a parallel groove clamp 1 includes a wire clamp 1-1 connected by a bolt 1-2, and the two sides of the wire clamp 1-1 are respectively provided with a barbed connection hole 1-3, a pull wire connection Holes 1-4, parallel groove clamp 1 connected to umbrella-shaped barb 2, umbrella-shaped barb 2 is composed of binding part 2-1 and steel strand wire 2-2 evenly distributed in an umbrella shape, and is composed of a 1-meter-long steel Stranded wire is disassembled and made.

[0011] When in use, install one side of the ditch clamp 1 on the backguy to be protected, and install the umbrella-shaped barb 2 on the other side. The installation position of the upper end of each stay wire is less than 5 meters from the cross arm of the pole, and a group is installed every 1 meter, and the installation starts at 2.5 meters above the...

Abstract

The invention discloses a barb mechanism for protecting transmission lines from antireflective films. The barb mechanism is characterized in that the mechanism comprises a parallel-groove clamp (1); the parallel-groove clamp (1) includes a clamp (1-1) connected by a bolt (1-2), and the two sides of the clamp (1-1) are respectively provided with a barb connecting hole (1-3) and a stay wire connecting hole (1-4); the parallel-groove clamp (1) is connected with an umbrella-shaped barb (2); and the umbrella-shaped barb (2) is composed of a bundling part (2-1) and steel strand wires (2-2) evenly distributed in an umbrella shape. The barb mechanism of the invention is simple and practical. By adopting the barb mechanism, the number of tripping times of transmission lines can be reduced, and safe operation of lines can be improved.

Description

Technical field: [0001] The invention relates to a barb mechanism for an anti-transmission line reflective film, and belongs to the technical field of power system transmission operation. Background technique: [0002] At present, transmission lines have been tripped many times due to floating objects such as reflective film. Usually, the towers of transmission lines are relatively high, and it is difficult for foreign objects to fly directly onto the lines. It reaches the cross-arm insulator, which causes the grounding trip of the transmission line. Because there are many orchards in Yantai area, orchard farmers use reflective film on a large area. The line trip caused by reflective film on the transmission and distribution line accounts for nearly 50% of all line faults every year. Among them, in 2013 and 2014, the 110kV Haijiu line and the 110kV Haijin line were tripped due to reflective film. Through inspection, it was found that the reflective film floated upward along...
