Technical Field

The invention belongs to the technical field of electric power construction, and particularly relates to a multifunctional grounding assembly for electric power equipment maintenance.

Background

In consideration of eliminating residual charges in equipment and avoiding the risk of sudden call, the power equipment is usually grounded before maintenance, and equipment to be maintained is connected with the ground through a grounding device, so that working (maintenance) personnel can safely carry out field work. Besides the grounding disconnecting link, a temporary grounding wire is also often hung on a working site to perform short-circuit grounding on the maintenance equipment.

The grounding wire is a grounding device composed of a wire clamp, a soft copper wire, a grounding terminal and the like, and in use, a contact electroscope is used for testing electricity of the hanging part, and then a matched insulating operation rod is used for completing the step of hanging the grounding wire. Because the grounding wire can be freely detached and moved, the grounding wire becomes a power equipment maintenance safety tool with extremely high usability.

However, the ground wires commonly used at present have the following inconvenience problems:

1. the ground wire is difficult to articulate. When the existing common grounding wire is arranged on an operating rod, a wire clamp of the common grounding wire and the operating rod form an included angle of 90 degrees which cannot be adjusted, and the angles of hanging points of different equipment to be overhauled are completely different, and are different from the horizontal to the vertical to the ground. In use, the phenomenon that the grounding wire is difficult to be hung frequently occurs due to the angle problem, and the workload of arranging safety measures is greatly increased.

2. The use of tools is numerous. Because hanging the earth connection in electrified way is equivalent to short circuit grounding of the electrified equipment, serious safety accidents can occur, and therefore, the three-level electricity testing needs to be carried out by using an electricity testing pen fixed at the front end of an insulating operating rod before grounding. In the process of hanging the ground wire, in order to keep enough safe distance, another corresponding insulated operating rod is also used for operation. Therefore, a plurality of insulating operation rods, a test pencil, a grounding wire and other devices are required to be carried in the process of one-time grounding. If two or more voltage levels are involved in a single operation, the equipment carried will be quite numerous.

Therefore, it is desirable to develop a novel grounding wire device, the joint of which can be adjusted at multiple angles to adapt to different working environments, and meanwhile, the electroscope is integrated into the grounding wire device in a matching manner, so that the number of tools required to be carried by the grounding wire can be reduced.
