Operation process for live-line equipotential access of power transmission line in river network area

Abstract

The invention discloses an operation process for live-line equipotential access of a power transmission line in a river network area. The method comprises the steps of checking the situation of a worksite, checking tools, instruments and materials, checking double names, arranging hanging points on a tower, arranging a transmission rope system, transmitting a pulley block system, enabling an equipotential electrician to enter equipotential, eliminating line defects, enabling the equipotential electrician to get out of the equipotential, enabling the equipotential electrician to sit in a ladder shaped like a Chinese character' shi 'and arranging the tower. The beneficial effects of the invention are that: t step A, reasonable and accurate data can be conveniently provided for erection of ariver network to ensure normal operation of a project step C, tools are convenient to take in and out, step D, a pulley system is ensured to provide enough labor-saving effect, the operation burden ofelectricians is reduced, the erection of wires is facilitated, and in the step A and the step E, the minimum combination gap is ensured to be 5.02 m, so that the pulley system meets the hot-line workcondition, and the operation space of users is ensured.

Description

technical field [0001] The invention relates to an operation process, in particular to an operation process for a power transmission line in a river network area charged in and out of an equipotential operation, and belongs to the technical field of transmission line erection in the river network area. Background technique [0002] With the rapid development of my country's power grid, the scale of power construction is getting larger and larger, and the transmission line equipment is also becoming larger and larger. The proportion of all lines is increasing, and the inspection of transmission lines is difficult and requires high quality. [0003] Although the existing operating technology is widely used, there are still some problems in the actual use process. First, there are many ditches, lakes and fish ponds in the river network mud swamp area. Compared with general transmission line projects, the traffic in the river network area is difficult. 1. The power operation is ...

Problems solved by technology

[0003] Although the existing operating technology is widely used, there are still some problems in the actual use process. First, there are many ditches, lakes and fish ponds in the river network mud swamp area. Compared with the general transmission line project, the traffic in the river network area is difficult. 1. The power operation is difficult, and there are higher requirements for the live operation of the transmission line. Second, according to the geological and topographical characteristics of the river network area, the live operation of the transmission line is restricted by the geographical division of the river network area and bridges, and the road is generally difficult to reach The location of the tower and the river network area have poor geology, high groundwater level, and the surrounding area of ​​the tower base is relatively narrow. Third, live work on overhead lines involves high-altitude work, which requires the cooperation of ground and high-altitude personnel, and requires a relatively flat place to place live work workers. Appliances, tools and appliances used in live work need more moisture-proof insulation, and when live work is carried out near or on the water in the river network, it is necessary to ensure that insulating tools and appliances such as insulating rods and insulating ropes are moisture-proof and cannot be in contact with water. Live work on transmission lines is restricted or there are potential safety hazards
