微地形区输电线路覆冰在线监测装置研究

严重的输电线路覆冰会造成断线、倒塔等事故,而严重的覆冰多处于微地形微气象区。通过对在线监测技术原理和输电线路覆冰理论的深入研究,针对微地形微气象区设计出一种新型的输电线路覆冰在线监测装置,解决了现有在线监测装置只能辅助人工巡视的局限性,并成功运用于输电线路,通过分析其采集数据验证了装置的可行性,可以更好地提高线路巡检工作效率和质量。

Study on On-line Monitoring Device of Transmission Line Icing in Micro Terrain Area

Severe icing on transmission lines will cause accidents such as line break and tower fall,while the severe icing is mostly in micro terrain and micro meteorological area. Based on the in-depth study of the principle of on-line monitoring technology and the theory of transmission line icing,a new type of on-line monitoring device for transmission line icing is designed for micro terrain micro meteorological area. It solves the limitation that the existing on-line monitoring device can only assist the manual inspection,and is successfully applied to the transmission line. The feasibility of the device is verified by analyzing its acquisition data,which can better improve the efficiency and quality of the line inspection.
