A monitoring and early warning device for snow cover thickness on high-voltage lines

Abstract

The invention discloses a snow cover thickness monitoring and early warning device for high-voltage lines, which belongs to the technical field of snow cover thickness monitoring and early warning for high-voltage lines. The early warning device is installed on the top of an electric tower, and the snow coverage of the sample line is used to feed back the coverage of high-voltage lines in the same area. For snow conditions, when the transect is covered with snow, use the laser receiver and laser transmitter to emit and receive laser light to achieve laser ranging and determine the snow thickness on the transect as safe snow cover thickness and low warning Which one of snow cover thickness and high early warning snow cover thickness can be used so that corresponding measures can be taken according to the actual snow cover situation. The line moves up and down, so as to shake off the snow on the transect, and reciprocate in this way, so as to monitor the number of times the transect reaches the high warning snow thickness within a certain period of time, so as to judge the snow coverage of the high-voltage line at that place Shock level.

Description

technical field [0001] The invention relates to the technical field of monitoring and early warning of snow cover thickness on high-voltage lines, and more specifically relates to a monitoring and early warning device for snow cover thickness of high-voltage lines. Background technique [0002] Power supply interruptions caused by ice and snow disasters on high-voltage lines in winter often occur. In winter, heavy snow covers high-voltage lines. Since high-voltage lines are located on high iron towers, and many iron towers are in mountainous areas, the transportation is inconvenient. This makes it difficult for people to Keep abreast of the snow coverage of high-voltage power lines. [0003] Long-term snow cover causes super high pressure on the high-voltage line. When the high-voltage line is oppressed by the thick snow layer and cannot be detected in time, it is difficult to take corresponding measures in time, which increases the load of the line, and the line is easily b...

[0002] Power supply interruptions caused by ice and snow disasters on high-voltage lines in winter often occur. In winter, heavy snow covers high-voltage lines. Since high-voltage lines are located on high iron towers, and many iron towers are in mountainous areas, the transportation is inconvenient. This makes it difficult for people to Keep abreast of the snow coverage of high-voltage wires

[0003] Long-term snow cover causes super high pressure on the high-voltage line. When the high-voltage line is oppressed by the thick snow layer and cannot be detected in time, it is difficult to take corresponding measures in time, which increases the load of the line, and the line is easily broken, resulting in line damage. Accidents such as accidents continue to occur, causing huge damage to the life of the country and the people; at the same time, although the snow cannot accumulate after a certain thickness, the continuous snowfall still causes pressure impacts on the high-voltage lines, and for long-term coverage It is also difficult to judge the impact pressure of snow on high-voltage lines due to snow conditions
