Analysis of transmission pole collapse damage pattern and development of safety protection device
摘要
Abstract
In order to solve the impact of transmission pole collapse accidents on the stable operation of the power system and safeguard power transmission,a transmission pole safety protection device was researched and manufactured with the transmission pole as the research object.Based on the analysis of typical accidents of transmission pole collapse,the mechanical characteristics of the collapse damage of transmission poles were clarified,the damage mode were mastered,the corresponding structure of the safety protection device of transmission poles was designed,and a simulation experiment platform to verify the practical effectiveness of the device was built.The results show that the main mode of transmission pole collapse damage is the tension generated by the foreign objects overriding the transmission line and acting on the transmission pole body along the line,which will lead to the collapse damage of the transmission pole when it exceeds the damage threshold of the transmission pole.The transmission pole safety protection device unloads the load by sacrificing the weak link,and accurately protects the transmission pole.The device can reduce all kinds of disasters on the transmission pole damage and losses due to the collapse accident of the pole,improve the emergency repair efficiency and the reliability of power supply.The developed safety protection device for transmission poles is characterized by simple structure and wide applicability,which can provide new reference for the disaster prevention in distribution network system.关键词
