Embodiment Construction
[0021] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] Such as figure 1 As mentioned above, it is a preferred embodiment of the free-stroke elastic wire clip of the present invention, which is a wire clip for an anti-shielding lightning rod, and is used to fix the anti-shielding lightning rod on an overhead ground wire. see figure 2 and image 3 , the wire clamp includes a wire clamp base 1, an elastic element 2, a movable clamp block 3 and a movable clamp block guide rod 4, the wire clamp base 1 has an elastic element seat 10 for placing the elastic element 2 and is located above the elastic element 2 The hanging wire part 11, the bottom of the elastic element seat 10 has a through hole (not shown) for the guide rod 4 to pass through, one end of the connecting ro...

The invention discloses an elastic wire clamp with free stroke. The elastic wire clamp comprises a wire clamp base, an elastic element, a movable clamping block and a guide rod of the movable clamping block, wherein the wire clamp base is provided with a elastic element seat used for holding the elastic element and a wire-hanging part above the elastic element; the bottom of the elastic element seat is provided with a through hole through which the guide rod passes; one end of the guide rod is connected with the movable clamping block, and the other end of the guide rod penetrates through the though hole; the movable clamping block pushes against the wire-hanging part under the action of the elastic element; and the wire-hanging part and the movable clamping block is provided with a first wire slot respectively and the two first wire slots are arranged oppositely. In the elastic wire clamp with free stroke, the movable clamping block pushes against the wire-hanging part of the wire clamp base under the action of the elastic element; and the movable clamping block has a larger free stroke, and the stroke length can be adjusted when the elastic wire clamp is in use; therefore the elastic wire clamp with free stroke is convenient to move and is suitable for places in which equipment is required to be suspended on overhead wires.
Description
technical field [0001] The present invention relates to clamps for power transmission lines, and more particularly, to a free-stroke elastic clamp for power transmission lines. Background technique [0002] Lightning protection of overhead transmission lines has always been the focus of line maintenance and transformation. A large number of statistics on line operation in my country show that, whether it is high-voltage or ultra-high-voltage transmission lines, lightning faults still account for 40-70% of line faults, especially in mountainous areas. The thunder and lightning shielding strike occupies a considerable proportion. [0003] Operational experience at home and abroad and combined analysis of faults show that lightning flashover of ultra-high voltage lines is still the main reason except for the counterattack of towers with high grounding resistance. A large number of lightning tripping faults are caused by relatively small lightning current, generally about 15-30K...
