Arc-extinguishing device and method for disconnecting and connecting power transmission and transformation lead in electrified manner

Abstract

The invention relates to the technical field of power transmission / transformation electrified disconnection lead wires, and provides an electrified disconnection power transmission and transformation lead wire arc-extinguishing device and method, a ground potential electrician can complete installation or disassembly of the arc-extinguishing device by using an operating rod, and the operation link that an equipotential electrician enters an electric field to assemble / disassemble the arc-extinguishing device is omitted; the hook realizes a locking insurance function through the movable buckle, and can be automatically closed to lock a lead when being hung on the lead, so that the arc extinguishing device is prevented from falling off in the use process, and the safety of live-line disconnection of the lead is ensured; two universal pulleys are arranged, when live-line lead disconnection and connection operation is carried out, a ground potential electrician can send an arc extinction rope and a transmission rope into an electric field together through an operating rod, an equipotential electrician does not need to carry the transmission rope to go in and out of the electric field, the steps that the equipotential electrician carries the transmission rope and installs the transmission rope are reduced, and the labor intensity of the equipotential electrician is reduced; an arc extinguishing rope and an insulation transmission rope are convenient to install, and the operation efficiency is improved.
