Novel ground wire clamp

Abstract

The invention belongs to the technical field of power detection and particularly relates to a novel ground wire clamp which comprises a clamping part, a connecting part and an operating rod. The clamping part is connected to the operating rod through the connecting part to form an L-shaped structure. A limit mechanism is arranged between the connecting part and the clamping part. The clamping partis provided with a hook clamp and a pushing clamp. The hook clamp is provided with a wiring hole and is slidingly connected to the pushing clamp. One end of the pushing clamping is movably connectedto the connecting part. The other end of the pushing clamp is slidingly connected to the hook. One end of the limit mechanism is fixedly connected to the hook, and the other end of the limit mechanismis movably connected to the connecting part. The connecting part is movably connected to the operating rod. According to the novel ground wire clamp, through the principle of a rotating shaft of a helical gear, a wiring clamp and a manual rotation operation rod are separated to form a core component which is an L-shaped operation mechanism, and a convenient grounding mode of a lead conductor in avertical direction is realized.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a novel grounding clamp. Background technique [0002] The grounding wire is a necessary safety tool in substation power outage maintenance work, which involves the personal safety of equipment maintenance staff and is very important. When the equipment is converted to maintenance after power failure, some equipment does not have a grounding switch device on both sides or one side. At this time, it is necessary to manually use an external grounding wire to hang on the associated conductor of the primary equipment. Grounded to complete the state of equipment maintenance. The grounding method of connecting the grounding wire and the conductor can not only allow the residual current of the equipment shell or the primary conductor to be released to the ground, but also avoid the induction potential caused by the induction effect during the power failure ...

AI Technical Summary

Problems solved by technology

This regulation makes a large number of line voltage transformers and other equipment with outgoing line intervals lack grounding switches. With the existing grounding line structure, it is necessary to use an aerial work vehicle to lift people to the same level as the line before they can be connected.

At the same time, in some areas of the substation, it is difficult for operating vehicles to enter, so it is very difficult to connect the grounding wire, which has caused problems in the application of the grounding wire

[0004] At present, the grounding wires used in substations are all connected in a straight line between the grounding clamp and the operating rod, and the conductors suitable for grounding are arranged horizontally and horizontally. However, most equipment such as CVT directly lead vertically from the terminal board to the frame jumper above. The traditional grounding wire will increase the difficulty for the operator to hang the wire, and the wire clip becomes a horizontal snap-in method, making the grounding difficult to stabilize. At the same time, the grounding contact area is poor, which seriously affects the grounding quality
