Problems solved by technology

Unnecessary power supply interruption for users of non-faulty lines due to line selection
Visual line inspection and positioning consume a lot of manpower and material resources, delaying the positioning time
These two methods are extremely incompatible with the high degree of automation of the modern power grid

Abstract

The invention discloses a transmission line fault monitoring system, comprising: a terminal monitoring device, a communication subsystem and a server arranged on each section of the monitored transmission line; a measurement module is used to monitor the data information of the transmission line, and upload the collected data in real time To the server; the terminal host aggregates, preprocesses and uploads the monitored data and collected data, and controls the terminal monitoring device according to the command sent by the server; the camera device monitors visible light video image data, and the infrared thermal imager collects infrared image data ; The camera device and the infrared thermal imager are set in the same airborne platform to ensure the correspondence between the infrared image data and the monitoring object; the microwave Doppler detector detects foreign matter intrusion into the transmission line; Surveillance, analysis and early warning requirements. Dividing the transmission line into several sections can construct accurate transmission line fault location, so as to realize rapid fault removal.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a transmission line fault monitoring system. Background technique [0002] During the operation of the power system, failures often occur. The unplanned power supply interruption caused by the failure will stop production, cause chaos in life, and even endanger the safety of people and equipment, resulting in very serious consequences. The statistics of the power system show that most of the faults in the distribution network operation are short-circuit faults, and more than 90% of them are single-phase ground faults. The main cause of short circuit is that the phase-to-phase insulation or phase-to-ground insulation of the current-carrying part of the electrical equipment is damaged. Therefore, after a single-phase ground fault occurs in the distribution network, if fast and accurate positioning can be achieved, not only can the line be repaired as soon as possible to ensure the rel...
