Description
Technical Field
The invention belongs to the field of distribution line application tools, and particularly relates to a device for quickly adjusting conductor sag.
Background
The sag is the vertical distance between the lowest point of the wire and a connecting line between two suspension points on the flat ground when the suspension heights of the wires on two adjacent base electric poles are the same. Generally, when the transmission distance is far, due to the dead weight of the wire, a slight sag is formed, so that the wire is in the shape of a catenary, if the heights of the suspension points of the wire on two adjacent electric poles are different, at this time, two sags appear in one span, namely two vertical distances from the two suspension points of the wire to the lowest point of the wire are called as a maximum sag and a minimum sag, theoretically, due to the fact that infinite force is required for straightening one wire, and such force does not exist in practice, if the sag of the wire of an electric line is too large, the distance between the lowest point of the line and the ground does not meet the safety distance required by design, and when a strong wind and the line have a short-circuit fault, the swing degree of the wire enables the inter-phase distance of the line to not meet the safety distance requirement, the service life of the cable is shortened, so that the sag is required to be reserved within a controllable range, therefore, the arc sag of the electric wire needs to be properly adjusted, but the electric wire needs to be disassembled and assembled again when the arc sag is adjusted at present, single adjustment is inconvenient, and if parts of an adjusting device are damaged, the arc sag cannot be continuously adjusted, so that the fault tolerance of the electric wire in the adjusting process needs to be increased, and the loss is reduced.
