Embodiment 1

[0042] Such as Figure 1 to Figure 6 As shown, the present invention discloses a device for quickly repairing damaged wires, including a wire tightener, a frame, an aluminum row and a pull wire, and the number of the wire tighteners is three, which are respectively the first wire tightener 1- 1. The second tensioner 1-2 and the third tensioner 1-3, the structure of the first tensioner 1-1 and the second tensioner 1-2 are symmetrical, and the number of the frames is two One, respectively the first frame 2-1 and the second frame 2-2 with symmetrical structure, the first wire tightener 1-1, the first frame 2-1, the second frame 2-2 and the second wire tightener The first wire tightener 1-1 is connected to the first frame 2-1, the second wire tightener 1-2 is connected to the second frame 2-2, and the third wire tightener 1-3 is fixed on the first frame 2-1, and the pull wire coiled on the second frame 2-2 and the first frame 2-1 is pulled by the third wire tensioner 1-3 and make...

Embodiment 2

[0051] Embodiment 2 is different from Embodiment 1 in that the wire tightener in Embodiment 1 is a ratchet wire tightener, and the wire tightener in Embodiment 2 is a double-hook wire tightener.

[0052] Such as Figure 1 to Figure 6 As shown, the present invention discloses a device for quickly repairing damaged wires, including a wire tightener, a frame, an aluminum row and a pull wire, and the number of the wire tighteners is three, which are respectively the first wire tightener 1- 1. The second tensioner 1-2 and the third tensioner 1-3, the structure of the first tensioner 1-1 and the second tensioner 1-2 are symmetrical, and the number of the frames is two One, respectively the first frame 2-1 and the second frame 2-2 with symmetrical structure, the first wire tightener 1-1, the first frame 2-1, the second frame 2-2 and the second wire tightener The first wire tightener 1-1 is connected to the first frame 2-1, the second wire tightener 1-2 is connected to the second fra...

Embodiment 3

[0059] Such as Figure 7 As shown, the present invention discloses a method for rapid repair of damaged wires, using the device of Embodiment 1 and performing the following operations,

[0060] S1 fixed tensioner and frame

[0061] Fix the first wire tightener 1-1 on the wire 6 on the left side of the broken strand point, fix the second wire tightener 1-2 on the wire 6 on the right side of the broken strand point, and connect the first wire tightener 1-1 with The first frame 2-1 is fixedly connected by a steel wire, and the second wire tensioner 1-2 is fixedly connected with the second frame 2-2 by a steel wire, the first wire tensioner 1-1, the first frame 2-1, The second frame 2-2 and the second wire tensioner 1-2 are distributed sequentially, and the third wire tensioner 1-3 is fixed on the first frame 2-1.

[0062] Open the connecting side panels of the two frames respectively, wrap the frame wrap around the wire 6, and then close the frame.

[0063] S2 coiled cable

Abstract

The invention discloses a device and method for quickly repairing a damaged wire and relates to the technical field of power maintenance. The device comprises a first wire tightener, a second wire tightener, a third wire tightener, a first frame, a second frame and a pull wire, wherein the first tightener, the first frame, the second frame and the second tightener are sequentially distributed, thefirst tightener is connected with the first frame, the second tightener is connected with the second frame, the third tightener is fixed on the first frame, and the third tightener pulls a pull wirecoiled on the second frame and the first frame to enable the first frame and the second frame to be close to each other. The method comprises four operation steps of S1, fixing the wire tightener andthe frame; S2, coiling a stay wire; S3, repairing the damaged wire; and S4, dismounting the fixed wire tightener and the frame. The device is advantaged in that the damaged wire can be rapidly repaired through the wire tightener, the frame, the stay wire and the like.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a device and method for quickly repairing damaged wires. Background technique [0002] In the rural distribution network, the phenomenon of broken strands of overhead conductors is often found in 10kV and 0.4kV lines, so it is necessary to eliminate them in time. [0003] The common reasons for stock breakage are: [0004] One is external damage, the other is that the wire has been running for too long, and the third is that there are hidden defects in the initial installation of the wire. [0005] The harm of broken strands of overhead conductors is self-evident, and they must be eliminated in time after discovery. [0006] The prior art usually adopts methods such as replacing wires, welding repairs, side auxiliary lines, and crossing lines. The replacement of wires has disadvantages such as long power failure time, high cost, and high labor intensity; wel...
