Research on Wind Resistance and Monitoring Technology for Pole-line Structure in Transmission Lines

[摘要] The research on wind resistance monitoring technology of typical cement pole-line structure in 10kv transmission line is carried out in view of the fact that the transmission lines in the coastal areas of South China are often threatened by typhoons. Firstly, a wind-resistant monitoring system for pole-line structures is established. Secondly, the method to determine the early warning value in the monitoring system is proposed and the whole finite element model of the pole-line is established. Then, the wind speed is transformed into wind load to determine the early warning value of wind speed according to the wind-pole fluid-solid coupling model. Finally, the correctness of the wind-resistant monitoring technology of the pole-line structure is verified by the results monitored by practical engineering. The research shows that the wind load on the surface of the conductor is non-uniform, which can be accurately calculated through the wind-pole fluid-solid coupling model; The structural response obtained by the whole finite element model of the pole-line structure can accurately reflect the actual stress state, which can be used to determine the early warning value of wind speed; The proposed wind-resistant monitoring system in transmission lines has been verified by practical projects and can be popularized.
