Abstract

The invention relates to a power distribution network line real-time monitoring and fault locating system, and relates to the technical field of electric power systems, and achieves power distribution line real-time monitoring and fault locating. The power distribution network line real-time monitoring and fault locating system comprises a power distribution station, a power distribution line, a positioning terminal, a plurality of line load switches and a plurality of line transformers. Each line transformer is connected with the power distribution station through the power distribution line; each line load switch is connected in series with the power distribution line, and the mounting point of each line load switch is provided with a camera used for shooting the on-off state of the line load switch; the positioning terminal is provided with a video signal input port, and the video signal output port of each camera is connected to the video signal input port of the positioning terminal. The power distribution network line real-time monitoring and fault locating system can judge the type of line faults quickly, and can achieve line fault positioning quickly.

Description

technical field [0001] The invention relates to power system technology, in particular to a technology of a real-time monitoring fault location system for distribution network lines. Background technique [0002] In the power system, when the transmission line fails, it is necessary to find out the fault point and repair the fault line in time to restore the normal power supply. [0003] The existing transmission line fault monitoring method is: set a monitoring node every certain distance on the transmission line, and install a fault indicating device on each monitoring node, an indicator is arranged on the fault indicating device, and the monitoring node is in normal state. In the power transmission state, the indicator of the fault indication device displays a normal color (such as white), and when a transmission fault occurs on the line section to which the monitoring node belongs, the indicator of the fault indication device displays a striking alarm color (such as red)...
