Description

Technical field

[0001] The invention relates to the technical field of power transmission line construction, in particular to a ground potential installation type shunt clamp device and an installation method thereof. Background technique

[0002] Heating caused by loose bolts or line overload is a common defect in line operation. Long-term heating or short-term overheating will cause the equipment life to be reduced or even damaged. The installation of shunt clamps to shunt is the basic method to deal with heating defects, and the effect is high. And the scope of application is wide.

[0003] At present, the shunt clamps are made of two aluminum clamps connected by drain wires and fastened by bolts on both sides. The installation of the shunt clamps is done by equipotential operation. The specific method is to install the two ends of the insulated hard ladder separately. At the cross arm of the tower and the conductor side (the hanging point is near the heating point), then the e...

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0021] The ground potential installation type shunt clamp device of the present invention, such as figure 1 As shown, it includes two wire clips 1, 2 on the left and right sides, and a drainage wire 3 connecting the two wire clips. The upper end of the left wire clip 1 is connected to a bracket 4, and the bracket 4 is fixedly connected to the right with a The upper end of the first bolt 5 and the right clamp 2 is provided with a through hole 6 having a diameter larger than that of the first bolt 5 and is sleeved on the first bolt 5. A rotating block 7 is hinged on the lower end of the right-side wire clamp 2. The rotating block 7 is provided with a threaded through hole 8 and a second bolt 9 is penetrated, so that the second bolt 9 can swing around with the rotation speed 7 or with the right The side clamp 2 rotates around the first bolt 5. A bayone...
