POWER DISTRIBUTION FACILITY LIVE-LINE WORKING METHOD

摘要

A power distribution facility live-line working method of the present invention comprises the steps of: erecting a new electric pole on a line of electric wires formed between existing electric poles; fixing an temporary arm part to the new electric pole; transferring an electric wire to an electric wire support part provided on the temporary arm part; positioning the electric wire to be in a higher position than the expected installation height of a pin-pole assembly by moving the temporary arm part or the electric wire support part upward, and moving, in a separating direction from the new electric pole, at least one of a plurality of electric wire support parts having electric wires transferred thereto; installing the pin-pole assembly on the new electric pole; moving, in the direction of the pin-pole assembly, the at least one of the plurality of electric wire support parts moved in a separating direction from the new electric pole; and transferring the electric wire from the electric wire support part to an LP insulator of the pin-pole assembly.
