Anti-release quick-assemble-disassemble grounding wire used on circuit side of open type switch cabinet

Abstract

The invention provides an anti-detachment quick assembly and disassembly grounding wire on the line side of an open switch cabinet. An anti-detachment quick-installation and disassembly grounding wire on the line side of an open switch cabinet, comprising an insulating rod and a frame-shaped frame with side openings at the top of the insulating rod, characterized in that: the middle side of the frame-shaped frame is fixed for The conductive hook hooking the bolt of the isolation knife switch and the clamping mechanism for clamping the gate of the isolation knife switch, the tip of the conductive hook faces the clamping mechanism. Without changing the function of the original grounding wire, a few parts are added to achieve easy and reliable assembly and disassembly of the wiring. Not only save labor but also improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of substation maintenance, and in particular relates to the assembly and disassembly work of the line-side ground wire of an open switch cabinet in a substation, and is widely used in the assembly and disassembly work of the line-side ground wire of an open switch cabinet of a power system substation. Background technique [0002] Assembling and disassembling the grounding wire is a safety work that is often done in substation maintenance and line maintenance work. It is an important technical measure to ensure safety in the power safety work regulations. It not only ensures the safe operation of the power grid and equipment, but also ensures the maintenance work. Personal and equipment safety is the top priority. [0003] Many open-type switchgears put into operation in the early years, due to their long history and design reasons, the assembly and disassembly of the grounding wire on the 10kV line side is ...

Problems solved by technology

These two methods have certain potential safety hazards, such as installing on the knife gate, because the knife gate is relatively narrow, and the grounding wire also needs to be installed horizontally, so the operator often needs to put his body into the switch cabinet, especially the body Short female team members cannot operate, which increases the risk of operation; if the grounding wire is installed on the screw that fixes the switch, although the operator does not have to put his body into the switch cabinet, since the screw is diamond-shaped, the grounding wire The clamps are flat, so it is easy to cause poor contact of the grounding wire, which poses a serious hidden danger to the safety inspection and accident handling of lines and switchgear.
