基于灾害预防的配电网架空线图像监测系统设计

Design of Aerial Line Image Monitoring Device for Distribution Network Based on Disaster Prevention

摘要: 配电线路走廊环境多样复杂，是电网可靠性的薄弱环节。经常面临如大型机械入侵施工、鸟巢活动、飘挂物、导线覆冰、火灾、树木生长等跳闸性事故风险。然而配网线路覆盖面广，也缺少相关的监控技术手段，导致运维人员无法及时高效解决线路故障及隐患。如何在故障、受灾等情况下，及时获取现场的可视化图像，评估故障及灾害的影响程度，对现场抢修工作进行远程指导，一直是配网管理中比较常见的安全生产难题。为应对配网架空线路各种灾害的监测要求，提出了一种基于配网图像监测装置的设计方案，设计方案包含了配电网架空线路图像监测装置样机的构架、夹具单元、图像采集单元、通信单元、等多个模块。

Abstract: The corridor environment of distribution lines is various and complex, which is a weak link of power grid reliability. It often faces tripping accident risks such as large-scale mechanical intrusion construction, bird's nest activities, floating objects, conductor icing, fire, tree growth and so on. However, due to the wide coverage of distribution network lines and the lack of relevant monitoring technology, operation and maintenance personnel cannot solve line faults and hidden dangers in a timely and efficient manner. How to get the visual image of the scene in time, evaluate the influence degree of the fault and disaster, and give the remote guidance to the emergency repair work on the spot under the condition of fault and disaster has been a common safety problem in distribution network management. In order to meet the monitoring requirements of overhead lines in distribution network, a design scheme of image monitoring device based on distribution network is proposed. The design scheme includes the frame, fixture unit, image acquisition unit, communication unit and other modules of the prototype of image monitoring device for overhead lines in distribution network.
