Abstract

The invention provides an online monitoring system for fault location of a transmission line, comprising: a plurality of current detecting devices, wherein at least three detection points are arrangedbetween two adjacent substations, and each detection point is provided with a current detecting device; sub-controllers, wherein each of the current detecting devices is connected to one sub-controller; a first wireless communication modules, wherein each sub-controller is connected to the first wireless communication module; a second wireless communication module, wherein the first wireless communication module is connected to the second wireless communication module; and a total controller, wherein the second wireless communication module is connected to the total controller, and the totalcontroller calculates a fault point position according to the detection data of each current detecting device. The online monitoring system for fault location of the transmission line solves the phenomenon in the prior art that the controller is prone to crash when one controller executes the fault occurrence judgment and the fault location finding at the same time.

Description

technical field [0001] The invention relates to transmission line fault detection, in particular to an on-line monitoring system for transmission line fault location. Background technique [0002] A Chinese patent discloses a transmission line fault location system with the application number CN201520275841.3. The transmission line fault location system includes: a sampling device connected to the transmission line; a data acquisition device connected to the sampling device; a fault starting device connected to the data acquisition device ; The wireless transmission device is connected to the fault starting device; the power supply device is connected to the transmission line, the data acquisition device, the fault starting device and the wireless transmission device; The time difference between the first fault waveform and the second fault waveform collected by the device, the transmission speed of the traveling wave in the transmission line, and the distance between the sa...
