基于高压输电线路的防外力破坏预警技术研究

Research on Early Warning System of Preventing External Damage for High Voltage Transmission Lines

输电线路分布区域广、传输距离长、地形条件复杂,超高车辆线下通行或超高机具线旁作业等外力破坏引发线路断裂、短路事故时有发生,这不仅给用电企业造成了经济损失,也对电网安全运行构成了严重威胁。这些事故的发生往往具有经常性、隐蔽性、突发性,致使日常巡视难以达到预期效果。为保护输电线路的安全,预防输电线路外力破坏隐患,本文设计和开发了一套输电线路防外力破坏预警系统,旨在有效减少或消除外力破坏事故,提高输电线路安全运行和智能化管理水平。

Power transmission lines are usually deployed in wide, long-distance and varied topography. Superhigh vehicles driving under, or superhigh machines working nearby may break or short-circuit the power lines. Further-more, serious economic loss and security threat will be caused by the power cut. Since the external damage happens often, covertly and unexpectedly, daily patrols by the power supply department are not sufficient and effective in management. To protect the power lines from being damaged externally, this thesis designed and devdoped a external damage precaution system fo r power lines to reduce external damage events even eliminate them so that safe operation and smart management of the power lines can be improved.
