Rapid grounding device for field high-voltage equipment

Abstract

The invention provides a rapid grounding device for field high-voltage equipment. The rapid grounding device comprises an upper clamp plate, a lower clamp plate, a clamp adjustment assembly, a locking assembly, a wiring clamp assembly and a ground insertion assembly. The upper clamp plate and the lower clamp plate adopts the clamp adjustment assembly to realize distance and clamp force adjustment between the upper clamp plate and the lower clamp plate; the locking assembly for locking the upper clamp plate and the lower clamp plate is arranged between the upper clamp plate and the lower clamp plate; the upper clamp plate or the lower clamp plate is connected with the wiring clamp assembly; and the lower portion of the wiring clamp assembly is connected with the ground insertion assembly. Through the cooperation of a gear and a toothed bar, the upper clamp plate and the lower clamp plate can be clamped accurately and conveniently; an electric wire is allowed to be connected between the upper clamp plate and the lower clamp plate, and reliability and stability of the wiring are improved; a constructor can connect the electric wire between the upper clamp plate and the lower clamp plate or clamp the electric wire in the wiring clamp assembly according to actual demand; and through rotating a force application nut, rapid insertion of an insertion pin can be realized.

Description

technical field [0001] The invention relates to the technical field of power distribution protection, more specifically to a quick grounding device for outdoor high-voltage equipment, which belongs to the technical field of electric power. Background technique [0002] In the power system, due to the aging, wear or overvoltage breakdown of the electrical device insulation, the original uncharged parts (such as metal bases, metal shells, metal frames, etc.) will be charged, or the original low voltage parts will be charged. Bring high-voltage electricity, these unexpected abnormal charging will cause damage to electrical equipment and personal electric shock casualties. In order to avoid such accidents, protective measures of protective grounding and protective zero connection are usually taken. Protective grounding refers to connecting the metal part of the electrical device that is not charged under normal conditions with the grounding device to prevent the part from being...

Problems solved by technology

At present, for high-voltage equipment in the field, it is generally necessary to use special equipment to ground it. However, the current grounding equipment structure is not perfect, and the grounding effect of the equipment is poor. For the limited field facilities, it is difficult to achieve fast grounding. Meet the requirements of fast grounding, resulting in low construction efficiency and poor reliability
