A hanging grounding device

Abstract

The invention discloses a throwing-hanging type grounding device. The device comprises a hook, the hook is of a U-shaped structure with a first opening, and the interior of the first opening is used for accommodating a wire. The hook is connected with a first rope and a second rope which are used for adjusting the orientation of the first opening of the hook, and a stop lever is arranged at the first opening, is hinged to one side of the first opening and rotates around a hinge point under the action of gravity, and is used for closing the first opening to limit the wire in the first opening,or opening the first opening to form a channel through which the wire can pass. The hook with the opening is matched with the stop lever for intermittently closing the opening, the stop lever is controlled by the gravity to limit the falling of the wire or open the opening to detach the hook, and the whole process only needs to be controlled through the two ropes, so that the operation difficultyis reduced while the connection stability of the grounding wire and the wire is guaranteed, and the operation efficiency and the grounding efficiency are improved.

Description

technical field [0001] This application relates to the field of high voltage power transmission, in particular to a throwing type grounding device. Background technique [0002] In the process of maintenance or laying of transmission lines, each line is not live, but for safety, the electric power safety work regulations stipulate: After the line experience is clear that there is no voltage, the grounding wire should be installed immediately and the three-phase short circuit should be installed. The branches that may come to transmit power to the working section of the power outage line must be tested and installed with grounding wires. The complete set of grounding wires should be composed of multiple strands of soft copper wires with transparent sheaths, and the cross-sectional area must not be less than 25mm. 2 , the installation process should use insulating rods or special insulating ropes, and the human body is not allowed to touch the ungrounded wires; Personnel thro...

Problems solved by technology

[0003] The inventor found that in the actual maintenance work, due to the limitation of the structure of the traditional grounding wire and the way of hanging, when hanging, the operator needs to throw the insulating rope, and accurately connect the opening of the grounding wire chuck to the wire, and the wire can only be clamped after the wire hits the tongue. However, every time the operator hangs a grounding wire, they need to try many times to succeed; when facing a tension tower with a large corner, the wire is far away from the cross arm, and the installation is more difficult, and even forced to change the installation. Towers, this will greatly prolong the working time, increase the workload of operators, and bring great potential safety hazards; there are other grounding wire structures, although the opening of the hook is enlarged, or it is not equipped with insurance, which is easy to fall off, or it is installed after the insurance is installed. The complexity of its operation is greatly increased; the existing traditional grounding wire is difficult to meet the requirements of high work efficiency, less workload, and small safety hazards during the suspension process; it is difficult to ensure safe and reliable successful installation of the grounding wire
