High voltage elevated transmission line remote electronic line-patrolling method

Abstract

The invention relates to a remote electronic line patrolling method for High Voltage Overhead Transmission Lines. The invention is characterized in that a front-end signal collecting system is arranged on each iron tower of the High Voltage Overhead Transmission Lines, and the front-end signal collecting system can communicate signals with a middle signal transmitting system. A plurality of front-end signal collecting systems share a middle signal transmitting system, which receives video frequency signals which are sent out by the front-end signal collecting system 1 and transmits control signals which are sent out by a back-end operating management flat roof system 3 for itself or the front-end signal collecting system 1. A plurality of middle signal transmitting systems 2 are connected with the back-end operating management flat roof system 3 via a local area network or the internet network 4. By using the method, a manager can make the line patrolling management without going out. The circulating status of the whole transmission line in real time can be known through the image information only by any computer which is connected on a control center of the network.

Description

technical field [0001] The invention relates to the application field of a network digital monitoring system, in particular to a remote electronic line inspection method for high-voltage overhead transmission lines, which allows the power operation management department to know the operating status of the power grid at all times through the monitoring system, and can detect in time Potential safety hazards in the operation process, so as to respond quickly and effectively to ensure the safe operation of the power grid. Background technique [0002] For a long time, the line inspection work of high-voltage overhead transmission lines still uses the method of manual line inspection. Under normal circumstances, manual line inspections are carried out at least monthly along the line to ensure the safe operation of the power grid. Line inspection is an indispensable job for the safe operation of the power grid. At present, line inspectors mainly rely on line inspectors to patrol...

AI Technical Summary

Problems solved by technology

Using this method, the problem of manual line inspection is still not solved, especially many lines are built in high mountainous areas, the lines are hundreds of kilometers or even thousands of kilometers long, it is normal that the wireless communication network coverage is not completely normal, and the emergence of blind spots makes this This method has limitations

[0006] 3. Some people have thought about the way of remote control aircraft patrolling the line, but in fact there is no progress
