Abstract

The invention discloses a safe assembly and disassembly device for high-voltage grounding wires, and belongs to the field of grounding wire assembling equipment in a power grid. The assembly and disassembly device comprises an insulated hollow insulation sleeve, a chuck, a pull rod and an operating trigger, wherein the chuck is arranged inside one end of the insulation sleeve; the operating trigger and a return spring of the operating trigger are arranged at the other end of the insulation sleeve; the pull rod connecting the chuck with the operating trigger is arranged inside the insulation sleeve; the chuck comprises a fixed joint, a fixed sheet and claws; the fixed joint is hollow; the triangular fixed sheet is arranged at the end part of the fixed joint; the three open-close type claws are articulated with three edges of the fixed sheet respectively; and the other end of the fixed joint is connected with the pull rod. The assembly and disassembly device is simple in structure, safe and reliable to operate, can improve the assembly and disassembly efficiency of the grounding wires, and can solve the problems of high-altitude falling of the grounding wires, and difficult operation due to rotating of the grounding wires with a brake pull rod in assembly and disassembly processes.

Description

technical field [0001] The invention belongs to the technical field of electric equipment grounding wires. Background technique [0002] The high-voltage grounding wire is used in the construction of lines and substations, in order to prevent electrostatic induction electric shock or false closing of the adjacent charged body, and to ensure safety. There are two types of high-voltage grounding wires: split-phase type and combined type, and the wire clamps are divided into two types: spring-loaded type and spiral type. Among them, the screw-type flat-mouth line clamp is suitable for power-off maintenance in copper and aluminum busbars and indoor switch cabinets, and the spring-compression type (double spring bayonet type) is suitable for power-off maintenance of 500 kV lines. The short-circuit grounding wire is composed of an insulating operating rod, a wire clamp, a short-circuit wire, a grounding wire, a grounding submersible, a confluence clamp, and a grounding clamp.
