低压线路故障查找与线路保护系统的应用分析

Low Voltage Line Fault Finding and Application Analysis of Line Protection System

低压线路运行状态直接影响着配网安全性能,已经成为新时期人们关注的焦点。本次研究过程中主要从低压线路的常见故障出发,分析低压线路故障查找与保护工作的要点,确保线路漏电或线路接地后能够第一时间实现报警与投切保护。并根据智能装置和云端系统,形成实时监测保护系统,从根本上提升了低压线路运行的安全性、可靠性和稳定性,为新时期电网建设提供了参考依据。

The operation status of low-voltage lines directly affects the safety performance of distribution network,which has become the focus of attention in the new era.In the process of this study,starting from the common faults of low-voltage lines,this paper analyzes the key points of fault finding and protection of low-voltage lines,so as to ensure that the alarm and switching protection can be realized at the first time after the line leakage or line grounding.According to the intelligent device and cloud system,a real-time monitoring and protection system is formed,which fundamentally improves the safety,reliability and stability of low-voltage line operation,and provides a reference for power grid construction in the new period.
