摘要
电力电缆以其安全、美观、可靠性高等优点,在城市电网中逐步取代了架空线路,成为电能输送的主要元件。针对常见的电力电缆故障,阐述了故障定位的基本步骤,并针对不同性质的故障类型,研究了相应的故障精测定点方法,探讨了其优缺点,为配电网电力电缆运行维护提供参考。
With its advantages of safety,beauty and high reliability,power cables have gradually replaced overhead lines in urban power grids and have become the main components of power transmission.Aiming at common power cable faults,the basic steps of fault location are expounded.For different types of faults,the corresponding fault precise determination method is studied.Its advantages and disadvantages are discussed to provide reference for the operation and maintenance of power cables in distribution network.
