Multifunctional ground wire insulating rod

Abstract

The invention discloses a multifunctional ground wire insulating rod, which comprises a ground wire clamp and an insulating rod, wherein the ground wire clamp comprises a fixed part and a movable part; the fixed part comprises an upper clamping plate; the upper clamping plate is a cavity body with an opening in the bottom surface; an arc-shaped recess is formed in the middle part of the cavity body; a longitudinal support rod and a movable rod are arranged in the cavity body; an elastic electric conductor is arranged between the support rod and the movable rod; the middle part of the elastic electric conductor is arranged in the arc-shaped recess; three fixing rings at least sleeve the elastic electric conductor along the arc length at equal intervals; the upper side of each fixing ring is connected with the lower end of a stretched spring; the upper end of the stretched spring is fixed with the upper clamping plate along the radial direction of the arc-shaped recess; the elastic electric conductor comprises a plurality of conductive copper wires which are arranged in parallel; one end of each conductive copper wire is fixed with the support rod; and the other end of each conductive copper wire is fixed with the movable rod and then can wind the periphery of the movable rod in a contracting and releasing manner. The multifunctional ground wire insulating rod has the advantages of being relatively wide in application range, convenient to use and firm to contact; meanwhile, the ground wire clamp has relatively good clamping force on a charged body; and the safety of using staff is ensured.

Description

technical field [0001] The invention relates to a grounding wire device, which belongs to electric engineering safety auxiliary tools, in particular to a multifunctional grounding wire insulation rod. Background technique [0002] The grounding line is the line directly connected to the earth, and it can also be called a safety return line. It can directly transmit high voltage to the ground in case of danger. In the power engineering system, the grounding wire is an important tool to ensure the staff when there is an unexpected voltage on the equipment and lines that have been powered off. According to the standard requirements, the ground wire must be 25mm 2 above bare copper flexible wires. The structure of the high-voltage grounding wire includes an insulating operating rod, a wire clamp, a short-circuit wire, a grounding wire, and a grounding terminal. [0003] At present, the bayonet of the grounding wire insulation operating rod used in substations is flat and can ...

Problems solved by technology

This invention realizes that the hook can be rotated relative to the insulating rod by setting a locking device between the hook and the top of the insulating rod, thereby solving the problem of using the hook at an angle, but the technical scheme adopted is more complicated and cannot achieve more accurate tilt angle control
