Description

A semi-automatic quick assembly and disassembly grounding hook and its operation method

technical field

The invention belongs to the technical field of mounting and dismounting grounding hooks, and in particular relates to a semi-automatic fast mounting and dismounting of grounding hooks and an operating method thereof.

Background technique

The short-circuit grounding wire is an important safety technical measure to ensure the safety of operators when electrical equipment and power lines are powered off for maintenance. The "lifeline" of electric power employees, only by standard and reliable hanging and removing of grounding wires can electrical accidents caused by grounding wires be avoided.

The grounding wire is mainly composed of three parts, which are the grounding hook, short-circuit wire, grounding electrode\grounding splint. The reliable connection of each component can ensure the effective short-circuiting of the wires and effectively prevent lightning strikes, misoperations, induced electricity and other accidents. The current will harm the personnel in the working area, and the grounding hook, an important component in the grounding wire currently used, has an ineffective and unreliable major safety hazard in the connection with the power wire, which directly threatens the personal safety of the maintenance personnel.

There are two types of single and double tongue reed grounding hooks and monkey head anti-dropping grounding hooks commonly used in electrical work:

1. The application and potential safety hazards of single and double reed type grounding hooks

This kind of grounding hook has a simple structure and low price, and is quick and convenient to assemble and disassemble. However, when it is installed at any angle, the actual contact surface with the wire will be too small, which cannot achieve the effect of effective and reliable conduction of current, and it is easy to fall off and the hook is locked. It will also damage the surface of the wire when it breaks away from the wire.

As shown in Figure 1 and Figure 2, the single- and double-tongued reed-type grounding hooks will form serious poor contact defects no matter at any installation angle, and are easily affected by the angle.

2. Monkey head anti-falling grounding hook:

At this stage, all maintenance units and departments of China Southern Power Grid use monkey head type anti-dropping grounding hooks. This type of hook can only clamp the wires and connect reliably when it is in an ideal state of 90° perpendicular to the power wires. There are large design flaws in the installation of corners, resulting in more serious potential safety hazards of unsafe and unreliable connection with wires, which seriously threaten the personal safety of maintenance personnel;

As shown in Figure 3, the reliable connection between the hook and the conductor can only be realized when the installation angle is ideal at 90°.

As shown in Figure 4, when the installation angle is not 90°, the pressure plate close to the inner side of the human body and the outer upper mouth of the caliper will be stuck due to force, and when the operator releases the grounding hook due to gravity, the hook will appear "hanging empty ring" The phenomenon and the unreliable connection of the wires cause serious safety hazards.

At the same time, there is an unreasonable ergonomics situation. Since the human wrist is used to twist the rod body to make the screw push column move back and forth to complete the firming and loosening of the wire, in an ideal state, the actual operation on the spot is measured. , It needs to be rotated about 60 turns when dismantling, and it takes about 1 minute. The installation and disassembly of a group of three hooks requires the operator to twist about 360 turns, and it takes about 6 to 7 minutes. Under the real working environment It takes about 50 minutes to assemble and disassemble the 10 kV tower wires, and about 60 minutes for the 35 kV line towers, and the operators are affected by the actual unfavorable working environment such as wearing insulating gloves and working at heights, making the operation more difficult. It consumes a lot of physical energy and increases the safety risk of operations. The extension of power outages will also cause adverse social impacts and economic losses in all walks of life.

In summary, the existing grounding hooks have the following problems:

(1) The reliability of the hook installation is affected by the angle, and there are serious potential safety hazards of unreliable connection;

(2) There is an unreasonable mechanism design in the monkey head anti-dropping hook, which is time-consuming and labor-intensive and has poor man-machine efficiency;

(3) Various types of grounding hooks currently in use have different degrees of clamping and friction damage to the surface of the wire;

(4) The head of the monkey head anti-dropping grounding hook is not fixed, and it will rotate under gravity. In actual operation, the operator will need to hold the short-circuit wire by hand to tighten and fix it, and then the opening will be oriented. There are serious violations and personal electric shock safety hazards. There are design security flaws;

(5) When removing the hook because it is far away from the body, the operator will inevitably touch the short-circuit line, which will cause serious violations and potential safety hazards of personal electric shock.
