AUXILIARY DEVICE FOR POWER DISTRIBUTION FACILITY LIVE-LINE WORKING, AND POWER DISTRIBUTION FACILITY LIVE-LINE WORKING METHOD USING SAME

摘要

A power distribution facility live-line working method of the present invention comprises the steps of: fixing an temporary arm part to an electric pole; transferring an electric wire connected to the electric pole to an electric wire support part provided on the temporary arm part; by moving the temporary arm part or the electric wire support part upward, separating the electric wire from an existing LP insulator pre-installed on a pin crossarm; moving, in a separating direction from the electric pole, at least one of a plurality of electric wire support parts having electric wires transferred thereto; removing the existing LP insulator installed on the pin crossarm; installing a new LP insulator on the pin crossarm; by moving, in the direction of the electric pole, the at least one of the plurality of electric wire support parts moved in a separating direction from the electric pole, bringing the at least one of the plurality of electric wire support parts close to the new LP insulator; and transferring the electric wire from the electric wire support part to the new LP insulator.
