⑤ The equipotential electrician opens the wire adjustment plate to adjust the slack of the wire.

In the step ③, the double wire is the upper wire, and the lock tackle is the upper tackle on the lock, and the upper tackle on the lock is installed on the upper eye of the double plate working eye, and the insulating rope is passed through the upper eye. Put the pulley on the lock head, and then pass through the pulley of the wire clamp along the wire, and carry the pulley on the lock head to lock the end along the opposite direction of the upper wire.

In the step ③, the double wire is the lower wire, and the lock block is a right-angle block. Head right-angle pulley, along the wire and then pass through the pulley of the wire clamp, along the opposite direction of the lower wire, lock the head on the lock right-angle pulley.

Advantage and effect that the present invention has are:

The method for adjusting the joints of multiple conductors with electricity on the 220kV-66kV transmission line of the present invention, the ground potential personnel on the tower hang the front end of the insulating hard ladder on the outside of the crimping pipe, and the rear end uses an insulating rope on the body of the iron tower to make the hard ladder as horizontal as possible, etc. Potential personnel carry pulleys, wire clamps, insulating ropes, and lock pulleys into the strong electric field. Install the wire clamp with a pulley at a distance of 1.0 meters from the crimping pipe, install the lock block on the suitable working eye of the two-joint plate, pass the insulating rope into the lock block, and then pass through the wire clamp into the pulley of the wire clamp. In the opposite direction of the wire, lock the end on the end block. The ground potential personnel put the leading end of the threaded insulating rope into the pulley of the iron tower cross-arm head, and use a twist mill under the tower to tighten the insulating rope so that the tension of the conductor is transferred to the insulating rope. The equipotentialist opens the wire adjustment plate and installs in the appropriate eye. The method makes the insulated hoisting rope bear force along the required working eye of the two-joint plate. The invention can reduce the number of power outages, improve the randomness of work and the reliability of power supply. almost. And it effectively solves the problem that the upper and lower wires touch each other and damage the wire due to the different latitude of the double wire. It is suitable for all insulation forms of line equipment from 220kV to 66kV, and has a very high versatility.

Detailed ways

The method for adjusting the seams of multiple wires with electricity in the 220kV-66kV transmission line of the present invention is to use the lock tackle to make the insulating rope bear the force along the required working eye of the two-piece board. Since this method requires resistance, the upper and lower wires cannot Simultaneous adjustments should be made separately.
