Description

Technical Field

[0002] The disconnection of the drainage wire of the distribution line is a routine project of live working in the distribution network and is widely carried out. In the traditional mode, the disconnection of the drainage wire requires two workers to operate on the pole at the same time. A main operator uses an insulated wire cutter to disconnect the drainage wire, and an auxiliary operator uses an insulated clamp rod to fix the drainage wire to prevent the drainage wire from swinging uncontrollably at the moment of disconnection. At the same time, in order to ensure a sufficient safety distance, the length of the insulated wire cutter is usually about 2m. The weight of the wire cutter itself plus the additional gravity caused by the tilt angle during use often requires the main operator to have sufficient strength and familiar use skills. Otherwise, at the moment the drainage wire is disconnected, the insulated wire cutter will fall sharply or even fall from a high altitude. And at this stage, due to the different lengths of the drainage wires, many working points of the longer drainage wires do not meet the safety distance of live working, resulting in many disconnection work cannot be carried out normally, and can only be carried out through power outage maintenance plan.
