Description

An electric tool for installing and removing grounding wires

technical field

The invention relates to the field of installing and disassembling grounding wires, in particular to an electric tool for installing and disassembling grounding wires.

Background technique

The top of the existing grounding operation rod is a fixed connector, which is used to connect the clamp of the grounding wire line end; the middle part of the grounding operation rod is an insulating part, the lower part of the hand guard in the middle is the grip part of the grounding operation rod, and the bottom of the grounding operation rod is Rotating the handle requires a lot of effort because the moment arm is short. During large-scale operations, the installation of multiple grounding wires can easily cause excessive fatigue and muscle soreness. When using the grounding rod to install the grounding wire, the tightening force varies from person to person, and there is no uniform standard. If the force is small, the line end clamp may not be tightened tightly, and if the force is too large, the line end clamp may be loose. Risk of becoming loose or deformed. According to the work experience of substation operation, it is found that the grounding wire is tightened by hand during installation, and the handle of the grounding operating lever needs to be rotated 10 times to hang one phase of the ground wire. 1 minute. And in the large-scale operation of the centralized maintenance of the substation, at least 20 pairs of 10kV grounding wires are operated. According to the estimated time above, it takes 20 minutes to hang 20 pairs of grounding wires. It does not include the time for operating other equipment. After the operation, the arm is numb, and the manual operation is time-consuming and laborious. Because the strength of the arm cannot keep up, the operation time is doubled, and the grounding wire may not be clamped. If the wire clamp is not in good contact, it will There are certain potential safety hazards, which may cause the grounding wire to fall off during work, injure workers or electrical equipment, and also violate electrical safety work regulations.
