Grounding gun for grounding wire of high-voltage equipment

Abstract

The invention discloses a grounding gun for a grounding wire of high-voltage equipment. The grounding gun for the grounding wire of the high-voltage equipment comprises a gun head and an insulation rod which are connected. A cavity is formed inside the gun head. A power source, an electromagnet and a pull switch are arranged in the cavity. A power source is connected with the electromagnet through the pull switch and a connection guide line. The upper end of a pull rope of the pull switch is connected with a movable contact of the pull switch. One end of the power source is connected with one static contact of the pull switch through a guide line. One end of an electromagnet coil of the electromagnet is connected with the other static contact of the pull switch through a guide line. A pull switch housing and a stay wire are electrical insulators. The power source and the electromagnet are connected with the inner wall of the cavity through an insulation rubber board. The lower portion of the gun head is provided with a gun head opening. The gun head opening is combined and connected with an electrical insulation end cover through a screw and a nut. The end cover is connected with the insulation rod. The grounding gun for the grounding wire of the high-voltage equipment is compact in structure and convenient to operate. The safety and reliability of the grounding wire assembling work can be ensured, personal injury to operators from high voltage is avoided, and the efficiency of the grounding wire assembling and disassembling work is improved.

Description

technical field [0001] The invention relates to the technical field of grounding protection equipment for high-voltage equipment, in particular to a grounding gun for grounding wires of high-voltage equipment. Background technique [0002] When high-voltage equipment such as substations, transmission lines, and distribution lines are powered off for inspection and maintenance, in order to ensure the safety of the staff, it is necessary to install grounding wires on the side that may receive electricity. Spring clips are mostly used in the equipment part. In order to ensure that the clips are firmly hung, the spring clips generally have a relatively large tension and contraction force. The grounding gun is a tool used for installing or removing the grounding wire. The existing grounding gun is manually forced to pull the spring clip apart. [0003] The existing grounding gun is manually forced to pull the spring clip apart. Due to the large tension and contraction force of ...

AI Technical Summary

Problems solved by technology

Due to the large tension and contraction force of the spring clip of the ground wire, a large force is required to pull it apart, which is not conducive to efficient work

At the same time, problems such as mechanical jamming often occur at the connection between the manual force part of the existing grounding gun and the steel wire of the gun head part, which brings a lot of trouble for the installation and removal of the grounding wire for switching operations. On the other hand, the mechanical jamming often damages the grounding Economic loss caused by gun replacement and maintenance
