架空输电线路三角支撑防风偏装置研究探讨

Research on Triangular Support Anti-wind Deflection Devices for Overhead Transmission Lines

风偏故障是导致架空输电线路停运的最主要原因之一,通过对风偏故障进行技术分析,结合现场实际运行情况,针对不同类型的输电线路铁塔总结出三角支撑防风偏装置,并成功应用于现场实际中。经过试验和实际运行证明,防风偏改造是成功的,有效避免了线路风偏跳闸事故。

Wind deflection fault is one of the most important causes of overhead transmission line outage. Through technical analysis of wind deflection fault, combined with the actual operation of the site, the triangle support anti-wind deflection device is summarized for different types of transmission line pylons and successfully applied to the actual site. After the test and actual operation, it is proved that the wind deflection prevention transformation is successful and effective, and the line wind deflection tripping accident is avoided.
