Wind-resistant reinforcing method for 10 kV beeline pole and windstay wire device

Abstract

The invention relates to a wind-resistant reinforcing method for a 10 kV beeline pole and a windstay wire device. The wind-resistant reinforcing method includes the steps of acquiring strong wind frequently-occurring time period data of a region where a 10 kV line needing wind-resistant reinforcing is located; selecting stay wire assembly and disassembly time nodes according to the strong wind frequently-occurring time period data; assembling and disassembling stay wires for the 10 kV beeline pole by the windstay wire device. The wind-resistant reinforcing method for the 10 kV beeline pole has the advantages that the windstay wire device easy for assembly and disassembly is used, and the stay wires are selected to be assembled and disassembled according to time periods affected by strong wind and normal time periods unaffected by the strong wind, so that the problems that an existing stay wire method is difficult to apply in special areas (such as farmland) due to large occupied area and insufficient flexibility can be solved effectively, windstay wire application of the 10 kV beeline pole can be popularized easily, and further, wind resistance of a power distribution network is improved.

Description

technical field [0001] The invention relates to the technical field of windproof reinforcement for electric pole lines, in particular to a windproof reinforcement method and a windproof wire pulling device for 10kV straight poles. Background technique [0002] The existing 10kV linear poles in the distribution network have a large proportion of low strength, and the anti-overturning bending moment is insufficient. In bad weather such as typhoons, it is easy to cause large-scale collapse and broken poles. Installing windproof guy wires on 10kV linear poles in the distribution network is one of the windproof reinforcement methods for distribution network lines. The windproof guy wires used in the existing 10kV linear poles are herringbone double-sided guy wires, which occupy a large area. For some areas, such as farmland areas, it is difficult to Promotional use. And after the cable is installed, unless its service life reaches the replacement period or it is damaged, the cab...

AI Technical Summary

Problems solved by technology

[0002] The low strength of the 10kV linear poles in the existing distribution network accounts for a large proportion, and the anti-overturning bending moment is insufficient, which is likely to cause large-scale collapse and broken poles in severe weather conditions such as typhoons

Installing windproof guy wires on 10kV linear poles in the distribution network is one of the windproof reinforcement methods for distribution network lines. The windproof guy wires used in the existing 10kV linear poles are herringbone double-sided guy wires, which occupy a large area. For some areas, such as farmland areas, it is difficult to promotional use

And after the cable is installed, unless its service life reaches the replacement period or it is damaged, the cable is generally not replaced or disassembled, and the effective time for windproof reinforcement is mostly in summer and autumn. This long-term fixed installation form is suitable for those who do not need windproof Some specific areas and specific activities (such as spring plowing in farmland areas) during the reinforcement period will cause certain obstacles, making it difficult to popularize and apply
