Description
Technical Field
The invention relates to the technical field of live working, in particular to an electric power line equipotential working method based on an aerial rope technology.
Background
At present, the latest electric transmission line equipotential operation methods include an insulating rope ladder equipotential method, a helicopter equipotential method, an insulating flat ladder equipotential method, a swing equipotential method and the like. The equipotential operation method of the helicopter is greatly limited by objective conditions, and a first-line enterprise cannot configure the live-line maintenance helicopter; the equipotential method of the insulating flat ladder and the swing needs to build a platform by means of a tower structure, so the method is only suitable for the operation environment with the maintenance position close to the tower; in the maintenance section far away from the tower in the middle of the span of the transmission line, an insulation rope ladder equipotential method is mostly adopted.
Although the equipotential method of the insulating rope ladder is suitable for most live working scenes, the method also has some obvious defects:
1. the rope ladder needs the operating personnel to climb up by self physical power, and transmission line's height is generally between 30 to 40 meters, and is probably higher under the special environment, therefore the operating personnel just consumed a large amount of physical power before getting into the equipotential and beginning to overhaul the work, has both reduced the efficiency of live-wire overhaul work, has also increased live-wire operation's potential safety hazard.
2. Traditional rope ladder operation method needs the earth potential operation personnel to get into the shaft tower of overhauing section one end in advance, utilizes insulating bar to hang the upset coaster to the wire in the stockbridge damper outside on, and ground operation personnel utilize insulating rope to pull the upset coaster to overhauing the position, can begin to hang the ladder operation. The operation process consumes the manpower too big, and the maintenance position is far away from the shaft tower moreover, and guardianship is inconvenient, has increased live working's potential safety hazard.
3. After the live-line maintenance work is finished, the equipotential operating personnel still need to climb down from the high-altitude operation position by means of self physical strength, and the turnover pulley still needs to climb up the tower by means of the earth potential operating personnel and is picked off from the conducting wire by means of the insulating operating rod.
Therefore, a new equipotential operation method for power lines is needed.
