Ground wire device for vertical high-voltage lead

Abstract

The invention discloses a ground wire device for a vertical high-voltage lead. The ground wire device for the vertical high-voltage lead comprises a bottom plate, a first clamp piece, a second clamp piece and an insulating rod, the bottom plate is arranged vertically, the first clamp piece is symmetrical to the second clamp piece, the first clamp piece and second clamp piece are rotationally arranged at two sides of the bottom plate, the bottom plate is provided with a closing mechanism for driving the first clamp piece and second clamp piece to rotate to contact with each other to tightly hold the high-voltage lead, one end of the insulating rod is connected with the bottom plate, and the other end of the insulating rod is provided with a separating mechanism for driving the first clamp piece and second clamp piece to rotate to separate from each other to loosen the high-voltage lead. The ground wire device for the vertical high-voltage lead has advantages of simple structure, easiness in clamping and disassembling, and firm clamping.

Description

technical field [0001] The invention mainly relates to the technical field of grounding wires, in particular to a grounding wire device for vertical high-voltage wires. Background technique [0002] At present, when testing power equipment, it is often necessary to disassemble the vertically arranged busbar grounding knife down-lead, line down-lead, and lightning arrester down-lead on the line side to facilitate equipment testing. However, when the down-conductors are disassembled, the down-conductors connecting the lines need to be grounded for protection. The current grounding wire usually uses a double-tongue hook type grounding wire, and its structure is an inverted U shape. This type of grounding wire is more convenient to operate on horizontally arranged wires or clamps, but when installed on a vertical down-conductor , its installation and disassembly are more difficult, because the hook is not reliable and it is easy to drop; and at present, there is no special plac...

Problems solved by technology

The current grounding wire usually uses a double-tongue hook type grounding wire, and its structure is an inverted U shape. This type of grounding wire is more convenient to operate on horizontally arranged wires or clamps, but when installed on a vertical down-conductor , its installation and disassembly are more difficult, because the hook is not reliable and it is easy to drop; and there is no special place for installing grounding wires on the down-conductor of the current line, which brings great difficulties to the grounding work of vertical high-voltage conductors
