Abstract

The invention discloses a laser tree branch growth preventing early warning system for a high voltage line and relates to the technical field of power transmission line maintenance. The system comprises a laser band modulation signal transmitting part, a displacement detection unit, a foreign body monitoring module, a scanning module, a display module, an alarm unit, a laser detection module, a storage module and a controller; and the foreign body monitoring module scans a high voltage line scene line by line by emitting a modulated light beam by virtue of a laser sensor, monitors foreign bodyinformation at the circumference of the high voltage line in real time and transmits the monitored foreign body information to the controller. The system disclosed by the invention has the advantagesthat the high voltage line scene is scanned line by line by emitting the modulated light beam by virtue of the laser sensor, a new scanned physical medium is compared and analyzed in 288 grids of a recoverable receiving part, whether the new physical medium is a tree branch or not is determined, and a distance from the tree branch to safe conductor sag is measured and a photo of a foreign body point is transmitted back, so that related personnel can be timely informed, work stress of mountain patrols is greatly reduced, work efficiency is improved, and safety of the high voltage line is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of transmission line maintenance, in particular to a high-voltage line branch growth early warning system. Background technique [0002] After the high-voltage line touches the tree branch, it will form a line ground, and the power distribution room will display the ground and give an alarm. The branch is grounded instantaneously when there is wind, and the part of the branch that touches the line will be burned and separated from the line, and the grounding is over at this moment. If there are conditions such as rain, snow or wet weather at this moment, and people touch trees or pass under trees, people will get an electric shock or be shocked by the step voltage. [0003] At present, most of the hidden dangers of tree barriers on high-voltage lines are manually inspected regularly. Manual inspection is time-consuming and laborious, and the occurrence rate of mistakes is high; the inspection process of hid...
