Ultra-high voltage power transmission line equipotential live working device and use method thereof

Abstract

The invention provides an ultra-high voltage power transmission line equipotential live working device. The ultra-high voltage power transmission line equipotential live working device comprises an unmanned machine and two insulation pulleys, wherein the two insulation pulleys respectively are an upper insulation pulley and a lower insulation pulley; each insulation pulley consists of a housing, a hook body, a roller and a hanging ring, the roller is arranged on the housing, a reverse hook body is arranged at the upper part of the housing, and the hanging ring is mounted at the upper part of the hook body; the unmanned machine is connected with the upper end of an insulation hanging rope, the lower end of the insulation hanging rope is connected with the hanging ring of the upper insulation pulley, a ladder rope is wound around the roller of the upper insulation pulley, the end part of the ladder rope is connected with the upper part of a ladder, and ladder hooks are arranged at the upper part of the ladder. By adopting the ultra-high voltage power transmission line equipotential live working device provided by the invention, a person can directly reach a repair line position to perform a repair operation and does not need to start to move from a pole, so that a lot of labor is saved; only one person can finish operations of the whole device to complete the repair operation, so that the labor is reduced.

Description

technical field [0001] The invention belongs to the field of electric power maintenance equipment, and in particular relates to an equipotential live working device for an ultra-high voltage transmission line and a method for using the same. Background technique [0002] Live work is a method of repairing and testing high-voltage electrical equipment without power failure. According to the relationship between the human body and the charged body, it can be divided into: equipotential work, ground potential work and intermediate potential work. In the equipotential live work, the operator needs to climb the tower or climb the soft ladder and walk to the maintenance position for live work. The human body is in contact with the high-voltage live wire, which is dangerous and poses a great threat to the physical, mental and psychological quality of the workers. test. [0003] At present, conventional equipotential live working methods for ultra-high voltage transmission lines in...

Problems solved by technology

[0003] At present, conventional equipotential live working methods for ultra-high voltage transmission lines include: "cross two sections and three" method, soft ladder method and swing method, but there are still many disadvantages: 1) If the maintenance location is near the middle of the line span and far away from the tower When using the main body, the operator needs to climb the tower or climb the soft ladder to the wire, and then live the wire to the working position, which greatly consumes the physical strength of the operator and affects the working time and efficiency; 2) Use the soft ladder method or swing method to perform equipotential live work 1 ground potential electrician and 4 ground electricians are required to cooperate, which is not conducive to the organization and implementation of the work; 3) In the live work on the narrow tower window pole tower, the requirements for the minimum safety distance of the combined gap are very strict harsh
