High-voltage line snow covering thickness monitoring and early warning device

Abstract

The invention discloses a high-voltage line snow covering thickness monitoring and early warning device, and belongs to the technical field of high-voltage line snow covering thickness monitoring and early warning. The early warning device is installed at the top end of the electric tower, and the snow covering condition of the high-voltage line in the same area is fed back through the snow covering condition of the sample line; when the sample line is covered with accumulated snow, laser ranging is realized by utilizing laser emission and receiving of the laser receiver and the laser emitter so as to judge whether the accumulated snow thickness on the sample line is a safe snow covering thickness, a low early warning snow covering thickness or a high early warning snow covering thickness, so that corresponding measures can be taken according to the actual snow covering condition, and meanwhile, when the high early warning snow covering thickness is reached, the electric push rod is controlled by triggering the intelligent starting piece to drive the sample wire to move up and down, so that accumulated snow on the sample wire is shaken off repeatedly; therefore, the number of times that the sample wire reaches the high early-warning snow covering thickness within a certain period of time is monitored, and the snow covering impact degree borne by the high-voltage wire at the position is judged.

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
