Multi-angle grounding wire suitable for substation

Abstract

The invention relates to the technical field of substation device inspection, and particularly relates to a multi-angle grounding wire suitable for a substation. The grounding wire comprises an insulation operation rod and an electric wire clamp used for clamping a high-voltage wire. A screw is connected between the electric wire clamp and the insulation operation rod. The electric wire clamp comprises a first contact and a second contact. The first contact is rotatably connected with the insulation operation rod. The second contact is movably connected with one end of the screw. An accommodating cavity which matches the high-voltage wire is formed between the first contact and the second contact. According to invention, high-voltage wires with different wire diameters can be effectively embedded; the positions of the high-voltage wires are fixed, and the high-voltage wires are prevented from slipping back and forth; in use, the angle of the first contact can be adjusted according to the field condition to adapt to horizontal and vertical high voltage wires at various angles; changing the direction of the insulation operation rod is not needed; the operation is easy; a contact surface is effectively fixed; and the installation of the grounding wire is firm.

Description

technical field [0001] The invention relates to the technical field of substation equipment maintenance, and more specifically relates to a multi-angle grounding wire suitable for substations. Background technique [0002] Before substation equipment maintenance, installing grounding wires on substation equipment is a basic measure to ensure the personal safety of maintenance personnel. The installation of grounding wires is directly related to the protection level of maintenance personnel. At the substation overhaul site, operating personnel often encounter difficulties in installing ground wires in some places and unreliable ground wires when installing ground wires. [0003] At present, there are two types of double-spring buckle-type grounding wires and flat-mouthed spiral-type grounding wires widely used in substations. When setting the ground wire, it is difficult to install the ground wire in some places, and the installation of the ground wire is not reliable; in ad...

At the substation overhaul site, operating personnel often encounter difficulties in installing ground wires in some places and unreliable ground wires when installing ground wires

[0003] At present, there are two types of double-spring buckle-type grounding wires and flat-mouthed spiral-type grounding wires widely used in substations. When setting the ground wire, it is difficult to install the ground wire in some places, and the installation of the ground wire is not reliable; in addition, the ground wire type widely used in the current substation cannot change the direction, and the operator can only change the direction of the insulating rod to make it Tower connection, cannot effectively fix the contact surface
