Typhoon disaster observation tower for transmission lines

Abstract

The invention discloses a typhoon disaster observation tower for transmission lines. At present, there is no actual observed data on the process in which typhoon acts on an actual transmission line tower, and there is no data support for anti-typhoon work in the transmission line design, construction, operation and other links. The typhoon disaster observation tower for transmission lines comprises a transmission line tower which is equipped with a video monitoring device, a mobile communication unit, a photovoltaic cell system, a micro meteorological monitoring unit, a tower material stress monitoring unit, and a power supply control system. The power supply control system supplies power to the tower material stress monitoring unit, the micro meteorological monitoring unit and the video monitoring device. The tower material stress monitoring unit, the micro meteorological monitoring unit and the video monitoring device transmit monitoring signals to the mobile communication unit. The typhoon disaster observation tower for transmission lines can provide a test platform for the research on the damage mechanism of tower materials under typhoon wind load, and accumulate monitoring data for the anti-typhoon work in the transmission line tower design, construction, operation and other links.

Description

technical field [0001] The invention relates to the field of disaster prevention and mitigation devices for power transmission lines, in particular to a typhoon disaster observation tower for power transmission lines. Background technique [0002] Experience in the operation of transmission lines shows that typhoons can cause wind deflection trips on transmission lines, damage to insulators and fittings, broken strands and wires of ground conductors, and damage to towers. For example, when typhoon "Yunna" landed in Zhejiang Province in 2004, 3,342km of transmission lines were damaged, and nine 220kV substations in the province lost power. It can be seen that the typhoon disaster had a serious impact on the safe operation of transmission lines. At present, the research on typhoon is mostly focused on the monitoring and analysis of wind field, and the mechanical tests of towers under the action of typhoon are mostly concentrated on the scaled-down model, and the wind tunnel te...

AI Technical Summary

Problems solved by technology

At present, the research on typhoon is mostly focused on the monitoring and analysis of wind field, and the mechanical tests of towers under the action of typhoon are mostly concentrated on the scaled-down model, and the wind tunnel technology is used to simulate the typhoon wind load; The size model is difficult to fully reflect the stress change of the tower material of the actual transmission line tower under the action of a real typhoon

[0003] Due to the lack of actual observation data on the process of typhoons acting on actual transmission line towers, the lack of monitoring methods for the damage mechanism of tower materials under the action of typhoon wind loads, resulting in a lack of data support for typhoon prevention work in the design, construction, and operation of transmission lines
