Distribution line fault detection method

The embodiment of the invention provides a distribution line fault detection method. The method comprises the following steps: disconnecting a fault line in a distribution line from a system power supply; a self-contained power supply is used for supplying power to the fault line; and detecting the fault line by using a detector so as to search a fault point in the fault line. The embodiment of the invention provides a fault detection method for a power distribution line, so as to safely, reliably, accurately and quickly detect a fault point. The power distribution line fault detection methodprovided by the embodiment of the invention is a basis for ensuring reliable power supply, and a 10KV high-voltage line within a range of dozens of meters of power supply does not exceed two hours anda low voltage does not exceed half an hour. 本发明实施例提供一种配电线路故障检测方法，包括：将所述配电线路中的故障线路与系统电源断开；使用自备电源对所述故障线路送电；使用检测仪对所述故障线路检测，以查找所述故障线路中的故障点。本发明实施例提供一种配电线路故障检测方法，以实现能够安全、可靠、准确、快速检测到故障点。本发明实施例提供的配电线路故障检测方法，是保证可靠供电的基础，供电几十里范围内的10KV高压
