Abstract

The invention provides an overhead power transmission line monitoring and early warning system which comprises a transmitting module, a receiving module, a transmitting end main control module and a receiving end main control module, wherein the transmitting module is connected with the transmitting end main control module and used for transmitting a detection signal; the receiving module is connected with the receiving end main control module and used for receiving the detection signal transmitted by the transmitting module; a monitoring space is formed between the transmitting module and the receiving module through the detection signal; the transmitting end main control module is arranged on a transmission line tower and used for controlling the work of the transmitting module; and thereceiving end main control module is arranged within a detection range and positioned at a transmission line tower except for the transmission line tower where the transmitting end main control module is, and is used for controlling the work of the receiving module and outputting a warning signal when a foreign object with the minimum length of L intrudes into the monitoring space and the moving speed is within the preset speed range. According to the invention, the monitoring coverage range of a monitoring and early warning system for a transmission line is enlarged, and timely warning can be realized.

Description

technical field [0001] The invention belongs to the field of electric power monitoring, and in particular relates to an overhead transmission line monitoring and early warning system and a working method thereof. Background technique [0002] Overhead transmission lines stretch for thousands of miles, and the terrain of the line corridors is complex and changeable. They are often damaged due to the invasion of external forces, such as cranes touching the lines, illegal construction, short-circuiting of foreign objects, and theft. These damages range from causing large-scale power outages to severe casualties. Therefore, when foreign objects invade, it is of great significance to monitor and warn the overhead transmission line in time before causing damage to the overhead transmission line. [0003] The existing overhead transmission line monitoring products have limited monitoring coverage, relatively weak monitoring signals, relatively low monitoring accuracy, and relativ...
