摘要
随着能源结构转型,新能源的发展直接促进远距离高压传输电网的建设,使其建设规模得到进一步的扩大。杆塔、线路故障越来越频繁,由此造成的直接或间接经济损失也越来越高。介绍了一种基于杆塔接地电流综合在线监测系统,通过有效、正确及时地掌握管区内输电线路的运行状态,利用接地电流对杆塔及输电线进行故障定位及分类,对预防重大停电事故的发生具有重要意义。
With the transformation of the energy structure,the development of new energy has directly promoted the construction of long-distance high-voltage transmission grids,which has further expanded the construction scale.Under the above background,pole and tower faults are becoming more frequent,and the direct or indirect economic losses caused by them are also getting higher and higher.Based on this,this article introduces a comprehensive on-line monitoring system for transmission towers,which effectively and accurately grasps the operating status of transmission lines in the pipeline area,uses grounding current to locate and classify the faults of towers and transmission lines,which can prevent major power outages.
