High voltage grounding wire apparatus

Abstract

The invention discloses a high voltage grounding wire apparatus. The high voltage grounding wire apparatus comprises an insulation operating lever, a wire terminal clamp and a power connection clamp, wherein the power connection clamp is in clamp connection with the wire terminal clamp in the circumferential-direction-spacing way; the wire terminal clamp is fixedly connected with the insulation operating lever; the insulation operating lever is hollow; an insulation operating handle is arranged at the middle part of the insulation operating lever and is spacing along the axial direction of the insulation operating lever; and the insulation operating handle is in threaded connection with the power connection clamp. When the high voltage grounding wire apparatus works, the power connection clamp which is in threaded connection with the insulation operating handle moves axially through rotation of the insulation operating handle, thus realizing adjustment of the distance between the power connection clamp and the wire terminal clamp so as to realize clamping and releasing of the wire. The wire terminal clamp and the insulation operating lever are fixed together; the insulation operating handle at the middle part of the insulation operating lever is used to drive the power connection clamp so as to guarantee that the insulation operating lever and the wire terminal clamp are fixed firmly so as to prevent unstable fixing of the wire or the ground wire because of rotation of the wire terminal clamp, thus guaranteeing the reliability for power supply and reducing the potential safety hazard.

Description

technical field [0001] The invention relates to the technical field of electric equipment, and more specifically, relates to a high-voltage grounding wire device. Background technique [0002] With the increasing scale of the power grid, the number of substations has increased, and the daily switching operations in the substations have also continued to increase. The safety and timeliness of installing and disassembling the grounding wire have become increasingly prominent. [0003] The high-voltage grounding wire is used in the construction of lines and substations, and is used to prevent electrostatic induction electric shocks near electrified bodies or to ensure safety when closing the switch by mistake. [0004] At present, the portable high-voltage grounding wire device in the substation includes: wire end clamp, connecting clamp, insulating operating rod, short-circuit wire and grounding wire, wherein, the conducting wire end clamp is connected with the insulating oper...

Problems solved by technology

[0005] However, the operation mode of the above-mentioned grounding wire is that the insulating operating lever easily drives the wire end clamp to rotate together during the fastening process, so that the fixing of the wire or the grounding wire is not firm, which brings a major hidden danger to the switching operation and affects This affects the reliability of power supply, and even endangers the safety of personal and equipment operation.
