Description
Technical Field
[0001] The utility model relates to the technical field of high-voltage line monitoring, in particular to a high-voltage line dancing process monitoring device. Background Art
[0002] The galloping of high-voltage transmission lines is a low-frequency, large-amplitude self-excited vibration generated under the influence of natural wind. When the wires gallop, it is easy to cause broken wires and loose bolts, which will cause damage to the tower materials. At the same time, in severe cases, the line jumper string will be damaged or the string will be dropped and danced, resulting in line arc burns, increasing the pressure on the tower, causing the tower to collapse and causing serious mechanical accidents. At the same time, when the transmission line gallops, due to the long duration and large amplitude, the amplitude of the line swing may exceed ten meters, and the swing trajectory naturally presents an elliptical shape. However, when the vertically arranged lines gallop, if the swing trajectory is in an elliptical state, it will cause a short circuit in the line; when the horizontally arranged lines gallop, the insulation gap between the wires and the obstacles is insufficient, and the high-voltage transmission line will discharge, bringing certain safety hazards to the natural environment. In general, the galloping of transmission lines will cause the insulation gap between wires, between wires and overhead ground wires, and between wires and towers or crossarms to decrease, thereby inducing cross-contact discharge between phases, causing repeated tripping of the line, and ultimately damaging the reclosing switch. If the conductor dancing continues for a long time, it will also pose a threat to the safe operation of the power grid, causing large-scale power outages and seriously affecting people's production and life.
[0003] In order to better prevent the high-voltage transmission line from galloping and reduce a series of losses caused by the transmission line galloping, a high-voltage line galloping process monitoring device is urgently needed to solve the above problems. Utility Model Content
