摘　　要：在输电线路中经常由于外部工况的变化导致输电铁塔的整体倾斜甚至产生倒塔事故的发生,而铁塔的倾斜必然会引起铁塔主材内力的变化,为了预防输电铁塔倾斜造成的铁塔倒塔事故,提出利用一种特制的应变式传感器来反应铁塔主材的受力状态,根据传感器输出值判断铁塔是否失稳,以此达到预警的目的,保证输电线路的安全正常运行。In transmission line,the change of external working conditions always leads to transmission tower whole inclination and collapse,which arouses the change of internal force of main material.In order to prevent transmission tower whole inclination and collapse,this paper proposes to adopt a unique strain sensor to reflect the behavior of main material and to judge the stability of tower according to the data given by the sensor,which realizes prewarning and guarantees the safe and normal running of transmission line.
