基于单防区振动光纤的高压电缆防外破监测预警装置研发

Development of a Monitoring and Warning Device for External Damage Prevention of High-voltage Cables Based on Single Zone Vibration Optical Fiber

外破电缆线路故障跳闸的重要原因,针对目前外破盯防依赖人工的问题,研制了基于单防区振动光纤的高压电缆防外破监测预警装置,利用分布式光纤振动传感器的机械振动传感能力,结合信息传输和告警技术,能够有效识别出多种型号的外破风险源,并将告警信息推送至外破盯防人员微信,将电缆外破被动盯防转为主动预警,有效预防外力破坏事件,提高供电可靠性。

In view of the current problem of uninterrupted staring and defensive relying on the tactics of the sea of people,this paper develops a high-voltage cable anti-external breaking monitoring and early warning device based on the vibration optical fiber of the single defense area,using the mechanical vibration sensing capability of the distributed optical fiber vibration sensor,combined with information transmission and alarm technology,can effectively identify a variety of types of external breach risk sources,and push the alarm information to the external breach and defense personnel WeChat,turn the passive monitoring of the cable into active early warning,and effectively prevent external damage incidents.Improve power supply reliability.
