Grounding device suitable for switch cabinet cable head and application method thereof

Abstract

The invention discloses a grounding device suitable for a switch cabinet cable head. The device comprises a grounding wire clamp, an insulating operating rod and a grounding wire, wherein the grounding wire clamp comprises arc-shaped tongue pieces, a bolt through hole, a left worm wheel, a right worm wheel, a worm, a limiting block, a fixing frame and a clamping head, the left worm wheel and the right worm wheel are mounted on the fixing frame, a worm is arranged between the left worm wheel and the right worm wheel and meshed with the left worm wheel and the right worm wheel, the arc-shaped tongue pieces are arranged at an upper end of the left worm wheel and an upper end of the right worm wheel respectively, the two arc-shaped tongue pieces are close to be O-shaped when closed, a bolt through hole connected with the grounding wire is formed in one arc-shaped tongue piece, and two horizontal chucks are symmetrically arranged at a lower end of the worm. The grounding device is advantaged in that an insulating operating rod comprises a clamping sleeve, a head rod, an upper coupler, a torque sensor, a lower coupler, a tail rod and an antiskid insulating handle, a wire clamp side copper nose is arranged at one end of the grounding wire, and a grounding side copper nose is arranged at the other end of the grounding wire. The invention further provides an application method of the grounding device suitable for the switch cabinet cable head. The device is advantaged in that the device is simple in structure, convenient to operate, safe and reliable, the power failure time is shortened, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power system operation tools, in particular to a grounding device suitable for a cable head of a switch cabinet and a use method thereof. Background technique [0002] The high-voltage grounding wire is used for line and substation inspection and maintenance, and is a necessary safety tool to prevent the electric shock generated by the adjacent live equipment or the accidental closing of the switch to cause the maintenance personnel to get an electric shock. Hanging the grounding wire is a safety barrier to protect the maintenance personnel, and it can also be said that the grounding wire is the lifeline of the maintenance personnel. The reliable connection of the ground wire is the key to ensure the safety of maintenance personnel. [0003] When the switchgear is overhauled, especially when it is necessary to overhaul the ground knife on the outlet side of the switchgear, it is necessary to hang the gro...

Problems solved by technology

Due to the difference in the arm strength of different operators, the clamping degree of the ground wire clamp is also different. Whether it is clamped reliably can only be based on experience.

The double-tongue grounding wire clamps the wire by the expansion and contraction force of the double-tongue spring, and the degree of clamping cannot be judged.
