Transmission line protection device

Abstract

The invention discloses a transmission line protection device, comprising a casing, wherein an up and down moving piece, a first connecting frame and a second connecting frame are arranged in the casing, and rollers are provided on the opposite sides of the first connecting frame and the second connecting frame. The first connecting frame and the second connecting frame are both provided with vertical grooves, the cleaning rods are slidably connected in the vertical grooves, the upper and lower moving parts are connected with a moving frame, and the moving frame is located between the first connecting frame and the second connecting frame, and the moving frame The side wall is connected with an arc-shaped cleaning plate through an elastic spring, and the lower end of the moving frame is connected with two inclined plates. The inclined plates are hingedly arranged with the moving frame. The end face is provided with a heating plate, the lower end of the heating plate is provided with a plurality of impact rods, and the lower end of the casing is provided with a plurality of circulation holes matched with the impact rods. The present invention facilitates the protection of power transmission lines.

Description

technical field [0001] The invention relates to the technical field of transmission line protection, in particular to a transmission line protection device. Background technique [0002] Snow covering of transmission lines in winter is one of the natural disasters of the power system. Due to the increase of ice and snow on the wires, certain mechanical damages will be caused to the wires, iron towers and hardware. When the ice and snow are severe, the wires will be broken, the tower will be collapsed, the wires will dance and flashover. The trip caused a large-scale power outage accident. Since the accident occurred in the severe winter season, heavy snow blocked mountains or frozen roads, the emergency repair conditions were very difficult, resulting in long-term power outages, which seriously threatened the safe and stable operation of the power grid and the reliability of power supply, and affected the national economy. cause heavy losses. [0003] Objects such as ice an...

[0002] Snow covering transmission lines in winter is one of the natural disasters of the power system. Due to the increase of ice and snow on the conductors, it will cause certain mechanical damage to the conductors, iron towers and fittings. Tripping caused large-scale power outages. Since the accident occurred in the severe winter season, the mountains were blocked by heavy snow or the roads were icy, making repair conditions very difficult, resulting in long-term power outages, which seriously threatened the safe and stable operation of the power grid and the reliability of power supply. cause heavy losses

[0003] The existing transmission lines are prone to sticking with ice and snow and other objects, which are prone to breakage
