Multifunctional ground wire insulation rod

Abstract

The multi-functional grounding wire insulating rod includes a grounding wire clamp and an insulating rod. The grounding wire clamp includes a fixed part and a movable part. The fixed part includes an upper splint. A vertical support rod and a movable rod are installed in the cavity, and an elastic conductor is arranged between the support rod and the movable rod. The fixed ring, the upper side of the fixed ring is connected with the lower end of the tension spring, and the upper end of the tension spring is fixed with the upper splint along the radial direction of the arc-shaped notch; the elastic conductor is composed of multiple conductive copper wires arranged in parallel, and the conductive copper wire One end of the utility model is fixed to the support rod, and the other end is fixed to the movable rod and can be retracted and wound around the outer periphery of the movable rod. The invention has a wide application range and is convenient to use. At the same time, the grounding wire clamp has a good clamping force on the charged body, and the contact is firm, ensuring the safety of users.

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
