Description

An adjustable double-row hook paralleling device for transmission lines

technical field

The invention relates to an adjustable double-row hook paralleling device for power transmission lines.

Background technique

On high-voltage transmission lines, in order to reduce the power loss caused by wire corona discharge and the interference to communication, split wires are generally used to transmit power. In my country's 220KV transmission lines, double-split wires are generally used. In order to prevent sub-wires between double-split wires If there is no phenomenon of mutual attraction, collision and entanglement under the action of wind force, a spacer bar is generally installed between the two sub-conductors, and the length of the spacer bar is generally designed according to the design spacing between the split conductors. When the spacer is initially installed, the ladder is generally used to hang on a sub-conductor, and the operator climbs the ladder to reach the installation position. However, the two sub-conductors will be pulled up and down by a certain distance under the gravity of the staff and the ladder itself. (Generally at 3-5m), if the sub-conductor above cannot be contacted, it will cause the operator to be unable to complete the installation of the spacer bar. Pull it back, but the success rate of throwing the rope is low, and the staff is difficult to use force, resulting in low installation efficiency of the spacer and high labor intensity of the staff.
