The failure of electric wires is inevitable. Therefore, effective, fast and accurate diagnosis and prediction of power line failures are the guarantee for the reliable and safe operation of power line power supply systems, especially overhead line power supply systems.

[0003] At present, the overhead power line fault detection work mostly uses personnel to climb ladders and hold non-contact test pens to perform segmented fault detection on the overhead cables because the overhead power lines are located at a high height. Since the entire power line is long, power maintenance personnel need to climb ladders repeatedly, which makes it difficult to determine the short-circuit location of the wire in a short time, and the efficiency of wire fault detection is low. Utility Model Content

[0004] The disclosed embodiment relates to a power fault detection device, which solves the problem of existing overhead power line fault detection operations. Because the overhead power lines are located at a high height, personnel usually climb ladders and hold non-contact test pens to perform segmented fault detection on the overhead cables. Since the entire power line is long, power maintenance personnel need to climb ladders repeatedly, making it difficult to determine the short-circuit location of the power line in a short time, resulting in low power line fault detection efficiency.

[0009] In at least some embodiments, the top of the hollow main pipe is symmetrically provided with two lower connecting holes, the bottom of the tension spring is connected to the lower connecting hole of the hollow main pipe, the left and right ends of the upper movable frame are respectively provided with upper connecting holes, and the top of the tension spring is connected to the upper connecting hole of the upper movable frame.

[0010] In at least some embodiments, the inner rod is slidably connected to the inside of the hollow main pipe, the top of the inner rod extends to the outside of the top of the hollow main pipe, and the top of the inner rod is rotatably connected to the upper movable frame.

[0011] In at least some embodiments, a movable sliding hole is formed on the outer side of the hollow main pipe, the movable sliding hole is L-shaped, a handle is provided at the bottom of the inner rod, and the handle provided on the inner rod is slidably connected to the movable sliding hole provided on the hollow main pipe.

[0012] The utility model provides a power fault detection device, which has the following beneficial effects:

[0013] When the utility model is in use, when the wire to be detected is located in the middle of the lower clamping wheel and the upper clamping wheel, the upper movable frame moves downward along the guide vertical hole under the influence of the tension of the tension spring, so that the lower clamping wheel and the upper clamping wheel are in contact with the wire.

When the handle moves to the top of the movable sliding hole, the upper movable frame moves upward to the topmost point, and the distance between the lower clamping wheel and the upper clamping wheel increases, so that the wire can reach the middle position between the lower clamping wheel and the upper clamping wheel. When the handle moves to the bottom of the movable sliding hole, the upper movable frame moves to the lowest end under the influence of the tension of the tension spring, and the distance between the lower clamping wheel and the upper clamping wheel decreases, so that the lower clamping wheel and the upper clamping wheel can contact with the wire, making the operation easier.
