Embodiment 1

[0016] exist figure 1 , figure 2 In the first embodiment shown, the disconnection self-falling transmission line fixing device includes a wire fixing piece 1 assembled on the power transmission frame; the wire fixing piece 1 includes a strip-shaped sliding hole 10 for the transmission line to pass through; the A wire pillow slider 11 that can slide up and down along the wire slide hole 10 is provided in the strip slide hole 10, and the transmission line 3 is pillowed above the wire pillow slider 11; A compression spring 12 is provided between the lower ends of the strip-shaped sliding holes 10 ; a cutting edge 13 is provided at the upper end of the strip-shaped sliding holes 10 .

[0017] In the above-mentioned power transmission line fixing device, the lower end of the compression spring 12 is fixed to the lower end of the strip-shaped sliding hole 10, and the upper end of the compression spring 12 is not fixed to the pillow wire slider 11, so that the compression spring 1...

Embodiment 2

[0021] For the wire fixing part 1, its second embodiment is as image 3 As shown, the difference from Embodiment 1 is that in the wire fixing member 1, the part surrounding the strip-shaped sliding hole 10 is formed by stacking rectangular frame-shaped silicon steel sheets, which is a silicon steel frame; the silicon steel An induction coil 101 is wound on the frame arm of the frame, one output end of the induction coil 101 is electrically connected to the cutting edge 13, and the other output end is electrically connected to the static electrode inside the strip-shaped sliding hole 10. Contact 102; the mutual contact surfaces of the strip sliding hole 10 and the pillow line slider 11 are provided with an insulating layer, and the induction coil 101 is arranged on the inside of the insulating layer on the strip sliding hole 10 to prevent contact with the pillow line The sliding block 11 rubs against each other; the side of the pillow thread sliding block 11 is provided with a ...

Abstract

The present invention provides a broken line self-falling off power transmission line fixing device. The device comprises an electric wire fixing member comprising a strip-like sliding hole from which a power transmission line penetrates, a line supporting sliding block capable of sliding up and down is arranged inside the strip-like sliding hole, and the power transmission line is arranged on the line supporting sliding block. A compression spring is arranged under the line supporting sliding block, the upper end of the strip-like sliding hole is equipped with a cutting edge, and a threading frame is also fixed on the electric wire fixing member and is symmetrically equipped with a pair of external threading holes from which the power transmission line can penetrate at the two sides of the strip-like sliding hole. A sliding frame capable of sliding forth and back in the threading frame is arranged at the inner side of the threading frame and is equipped with a pair of internal threading holes from which the power transmission line can penetrate at the two sides of the strip-like sliding hole, the internal threading holes are lower than the external threading holes, and when the sliding frame slides to the limit position of any side, the penetration-through area of the internal hole and the external hole at the side is less than the cross-section area of the power transmission line. The broken line self-falling off power transmission line fixing device is assembled on a power transmission rack, and enables the broken power transmission line to fall off from a power grid totally when the power transmission line breaks accidently, thereby eliminating the potential safety hazards.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular, to a power transmission line fixing device. Background technique [0002] For the current transmission line, when the transmission line is broken, the broken line will sag to the ground, and a step voltage will be generated on the ground, or the broken line of the transmission line will directly contact the human body or combustibles on the ground, which will cause great danger. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a broken wire self-falling transmission line fixing device, which is assembled on the power transmission frame, and can make the broken transmission line fall off from the power grid completely when the power transmission line breaks accidentally, so as to Eliminate security risks. [0004] The technical solution adopted by the present invention to solve the technical problem is:...
