A kind of operation method for carrying electricity in and out of the transmission line in the river network area

Abstract

The invention discloses an operation method for the equipotential entry and exit of a transmission line in a river network area, including checking the situation of the work site, checking the tools and materials, checking the double name, arranging the hanging points on the tower, laying the transmission rope system and the transmission pulley block system 1. The equipotential electrician enters the equipotential, the line eliminates the defect, and the equipotential electrician exits the equipotential. The equipotential electrician sits on the ladder and arranges the tools on the tower and descends the tower. The beneficial effects of the present invention are: in step A, it is convenient to provide reasonable and accurate data for the erection of the river network to ensure the normal operation of the project; in step C, it is convenient to take tools, and increase the number of operators to improve work efficiency. D. Ensure that the pulley system can provide sufficient labor-saving effect, reduce the operating burden of electricians, and facilitate the erection of wires. In steps A and E, ensure that the combined gap is at least 5.02 meters, so that it meets the live working conditions and ensures the safety of users. operating space.

Description

technical field [0001] The invention relates to an operation method, in particular to an operation method for a power transmission line in a river network area charged in and out of an equal potential, 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 operation methods are 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 and mud swamp area. Compared with the general transmission line project, the traffic in the river network area is difficult. 1. The power operation is diffi...

Problems solved by technology

[0003] Although the existing operation methods are 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 and 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 above water in the river network, insulation rods and insulating ropes and other insulating tools and appliances must be protected from moisture and cannot be in contact with water. Therefore, near water or on water Live work on transmission lines is restricted or there are potential safety hazards
