A live working method for vertically arranged conductors

Abstract

The invention relates to a live working method for vertically arranging conducting wires, which comprises the following steps: using the drone pilot to control the unmanned aerial vehicle to the ground wire and the conducting wire below the working phase in stages, and throw out the guiding wire; Conductors, materials and tools weight, adjust the load of the counterweight truck; ground operators pull the insulating rope through the guide wire, so that the end of the insulating rope crosses the conductor and returns to the ground, so that one end of the insulating rope is fixedly connected to the ground, And tie the backup protection rope to the ground wire counterweight truck, and then control the counterweight truck to climb to the wire along the other end of the insulating rope to complete the wire introduction; the equipotential workers enter the electric field, install the outlet tools, and fasten the upper counterweight truck The back-up protection rope; the equipotential operators work out the wires, and the ground operators control the walking speed of the counterweight truck manually or automatically, and follow the operators to keep moving synchronously. This operation method can effectively guarantee the safety of workers working on the upper wire.

Description

technical field [0001] The invention relates to a live working method for vertically arranging conducting wires to lead out. Background technique [0002] At present, there are mainly the following three problems in carrying out 110kV-220kV same-tower erection of double-circuit lines and long-distance outgoing conductor live work. One is the problem of insufficient distance between phases after single-phase conductor load. After equipotential workers carry materials and tools, the concentrated load on the conductors can sometimes reach more than 1000N, which will inevitably reduce the phase-to-phase safety distance from the lower conductors, increase the sag of the working phase conductors, and easily cause insufficient safety distances between phases, endangering operations. To ensure the safety of personnel, an object of the same weight as the workers must be placed on the lower wire to ensure the safety of phases. In case of emergency, such operations can only be carried...

Problems solved by technology

After equipotential workers carry materials and tools, the concentrated load on the conductors can sometimes reach more than 1000N, which will inevitably reduce the phase-to-phase safety distance from the lower conductors, increase the sag of the working phase conductors, and easily cause insufficient safety distances between phases, endangering operations. For the safety of personnel, an object of the same weight as the worker must be placed on the lower conductor to ensure the safety of the interphase. In case of emergency, such operations can only be carried out by applying for a power outage.

The second is the problem of backup protection for long-distance lead-out operations

When the slope of the wire is large, it is difficult to pull the pulley, which not only increases the labor intensity of the operators, but also tends to cause the pulley to pull the wheel and the wheel to be deflected.

The third is that it is difficult to carry out the load test in advance. When the conductor encounters serious external damage such as mountain blasting, there may be invisible damage that is easily overlooked.
