西双版纳电网高压架空输电线路所经的地区地形复杂,具有雷暴活动频繁、高海拔、山区、高土壤电阻率等特点,因此,版纳电网架空输电线路的防雷任务较重。多年运行数据显示,因雷害造成的线路跳闸占线路总跳闸次数的70%以上,雷击跳闸一直是影响线路安全稳定运行的最主要因素。面对严峻的形势,西双版纳供电局积极开展防雷和抢险工作。防范雷害于未然事故处理的一般性原则是迅速限制事故的发展,消除事故根源,解除对人身、电网和设备的威胁。西双版纳供电局输电所从
Xishuangbanna power grid overhead transmission lines through the area of complex terrain, with frequent thunderstorms, high altitude, mountain, high soil resistivity and other characteristics, therefore, Banna overhead transmission line lightning protection task heavier. Years of operation data show that the line trip caused by lightning damage accounted for more than 70% of the total trips of the line. The lightning trip has always been the most important factor affecting the safe and stable operation of the line. Faced with the harsh situation, Xishuangbanna Power Supply Bureau actively carry out lightning protection and rescue work. The general principle of preventing mine damage from unplanned accidents is to rapidly limit the development of accidents, eliminate the root causes of accidents and relieve the threats to people, power grids and equipment. Xishuangbanna Power Supply Bureau from the
