Problems solved by technology

[0008] Aiming at the technical problem that the existing insulating soft ladder equipotential method requires the equipotential workers to climb up and down the soft ladder, the physical exertion is large, and the ground potential electrician is time-consuming and laborious to climb the tower and hang the pulley, the present invention provides a power line equipotential based on the high-altitude rope technology. Compared with the existing insulating ladder equipotential method, this method can save the physical strength of the operators, improve the maintenance efficiency and live safety level

Embodiment 1

[0034] Embodiment 1 A method for equipotential operation of power lines based on high-altitude rope technology

[0035] Such as figure 1 As shown, the equipotential operation method for power lines based on high-altitude rope technology includes the following steps:

[0036] S1: Hang a heavy object on one end of the guide rope 2, connect the other end with the traction rope 3 in series, use the UAV 1 to hang the guide rope 2, and the UAV 1 crosses the wire to be overhauled, and connect the guide rope 2 together with the weight Objects are dropped together, so that the guide rope 2 crosses the wire to be overhauled;

[0037] S2: Pull the guide rope 2, so that the traction rope 3 crosses the wire to be repaired and returns to the ground;

[0038] S3: fix the maintenance platform 4 on the other end of the traction rope 3, set a traction machine 9 on the ground, the traction machine 9 is provided with an insulating transmission rope 6, and the other end of the insulation transmi...

Embodiment 2

[0042] Embodiment 2 A power line equipotential operation method based on high-altitude rope technology

[0043] On the basis of embodiment 1, working method also comprises the steps:

[0044] S7: The ground staff use the guide rope 2 to lift the traction rope 3, remove the inspection platform 4 from the wire to be inspected and lower it to the ground;

[0045] S8: Remove the guide rope 2 and the traction rope 3 .

Embodiment 3

[0046] Embodiment 3 A power line equipotential operation method based on high-altitude rope technology

[0047] On the basis of embodiment 1, the ascender 8 is a chest type ascender, and the model is PETZL AVAO BOD CROLL FAST (S-L);

[0048] The model of the descender 11 is PETZL ID;

[0049] The backup protector 7 model is PETZL EAC.

Abstract

The invention relates to the technical field of hot-line work, in particular to a power line equipotential operation method based on a high-altitude rope technology, which comprises the following steps: allowing a guide rope to cross a to-be-overhauled wire; enabling a traction rope to cross the to-be-overhauled wire and return to the ground; enabling a maintenance platform to be hung at a maintenance position of the to-be-overhauled wire; under the action of a traction machine and a pulley, transmitting an equipotential operator to the maintenance platform such that the equipotential operatorenters an equipotential state; carrying out live maintenance work; and allowing the operator to land on the ground by using a descender. Compared with an existing insulation rope ladder equipotentialmethod, the operation method provided by the invention can save the physical strength of the operator and improve the maintenance efficiency and the electrified safety level.

Description

technical field [0001] The invention relates to the technical field of live working, in particular to an equipotential working method for power lines based on high-altitude rope technology. Background technique [0002] At present, the latest equipotential operation methods for transmission lines include the equipotential method of the insulating ladder, the equipotential method of the helicopter, the equipotential method of the insulating flat ladder, and the equipotential method of the swing. The helicopter equipotential operation method is limited by objective conditions, and the first-line enterprises cannot configure live maintenance helicopters; the insulating flat ladder and swing equipotential method need to build a platform with the help of the pole tower structure, so it is only suitable for the operating environment where the maintenance position is close to the pole tower; In the maintenance section of the transmission line stalls that is far away from the line t...
