架空输电线路故障分析及应对策略研究

Analysis of Overhead Transmission Line Faults and Study of Countermeasures

随着城镇化水平不断提升,建设用地的高密度开发,架空输电线路的运维环境遭到较大破坏,跳闸次数不断增加。通过对近十年山东某地区架空输电线路运行状况的分析研究,得出造成线路跳闸的主要原因及故障特点,并结合当地城市发展和线路运维状况,从技防、物防、人防等维度给出运维策略,有效降低了架空输电线路的跳闸次数,提高了城市电网的安全性与稳定性。

With the continuous improvement of the level of urbanization and the high-density development of construction land,the operation and maintenance environment of overhead transmission lines has been greatly damaged,and the number of trips has continued to increase.Through the analysis and research of the operation status of overhead transmission lines in a certain area of Shandong in the past decade,the main causes and fault characteristics of line trips were obtained.Combining with the development of the local city and the operation and maintenance status of the line,the technical,physical,and civil air defense dimensions were taken into account.The operation and maintenance strategy was given,which effectively reduced the number of trips of overhead transmission lines and improved the safety and stability of the urban power grid.
