Embodiment Construction

[0006] Embodiments are described in detail with reference to the accompanying drawings. A tension field layout device for single-way replacement of a double-circuit line, including a wire reel 1, a wire grounding trolley 2, a tension machine 3, a tension ground wire 4, a ground wire and a ground anchor 5, and a wire 6. The wire reel 1 and the tension machine 3 are all fixed on the ground through the ground net and the ground anchor 5, the tension machine ground wire 4 is connected to the tension machine 3 and the ground, and the described wire 6 is drawn from the wire reel 1 and connected after passing through the tension machine 3 To the electric tower, the wire grounding trolley 2 is connected to the wire 6 and the ground. The invention can effectively solve the problem that the double-circuit line needs to be cut off at the same time in the previous work of replacing the single-line conductor of the double-circuit line on the same tower, and greatly improves the reliability...

Abstract

The invention discloses a tension field arrangement device for wire replacement of a one-way circuit in a double-circuit line. The tension field arrangement device comprises a wire plate, a wire ground pulley, a tensioner, a tension ground wire, a ground grid and ground anchors, as well as a wire, wherein the wire plate and the tensioner are fixed on the ground through the ground grid and the ground anchors; the tension ground wire is connected with the tensioner and the ground; the wire is led out from the wire plate, and passes the tensioner to be connected with a wire power; the wire round pulley is connected with the wire and the ground. By the adoption of the device, a problem that simultaneous power cut is required when wires of the one-way circuit in the double-circuit line on the tower are replaced in the prior art is solved, and the reliability of power supply is greatly solved.

Description

technical field [0001] The invention relates to an auxiliary device for maintenance of a double-circuit line, in particular to a tension field arrangement device for a single-way replacement conductor of a double-circuit line. Background technique [0002] The current transmission lines use a large number of double-circuit or even multiple-circuit lines on the same tower, especially in the power grid around the city due to the tight land use and narrow line channels, often only two lines on the same tower are used as backup for each other, while the previous double-circuit lines on the same tower are replaced During the work of the conductors, the double-circuit line must be cut off at the same time before the construction can be carried out. This will cause all the substations to lose power, which seriously affects the reliability of power supply. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a ...
