1 城市配网架空线路运行分析及提升目标
1.1 配网架空线路问题分析
一是城市配电架空线路设备受历史因素影响,整体设备运行年限较久,设备老旧情况较为严重,故障频发;部分县域在雨季期间,雷击故障多发;配电架空线路绝缘化率整体较低,除市区架空线路基本实现绝缘化外,远郊区县配电架空线路裸导线占比较大,在大风、降雪等恶劣天气下,极易发生搭挂异物、树碰线等原因造成配网故障。二是设备本体故障占比较高,设备本体缺陷隐患引发故障较多。避雷器、绝缘子等设备本体故障发生率较高,该类设备运行年限较长,常规巡视手段发现缺陷困难,需加大力度彻底消除该类设备隐患。
1.2 提升目标
建立配网综合治理常态机制,充分发挥配电线路计划停电作用,连续每年完成80条故障率较高的配电线路的治理工作,实现配网整体故障率下降20%以上目标。……
