Pressing type grounding wire joint connecting device

Abstract

The invention discloses a pressing type grounding wire joint connecting device, which comprises a wire clamp, wherein the bottom of the wire clamp is provided with a fixed contact, the fixed contact is provided with a movable contact, and the bottom of the movable contact is connected with a grounding wire; the fixed contact includes a cylindrical body fixed at the bottom of the wire clamp, the bottom of the cylindrical body is provided with an inserting port, the inserting port is internally provided with an extrusion spring, and the inner wall at the bottom of the inserting port is providedwith a plurality of uniformly distributed clamping slots; and the movable contact includes an upper inserting head, the bottom of the upper inserting head is provided with a grounding wire sleeve, andthe side wall surface of the upper inserting head is provided with clamping blocks matched with the clamping slots. The device has the characteristics that the firmness of grounding wire connection can be improved, the labor intensity of operators can be reduced, and the assembly efficiency can be improved.

Description

technical field [0001] The invention relates to a ground wire joint structure, in particular to a push-type ground wire joint connection device. Background technique [0002] In order to ensure the safe operation of the 220kV system in the switch station of the hydropower station, a combined grounding device is generally used. The combined grounding device consists of an insulating operating rod with a clamp, a grounding wire, and a three-phase grounding terminal. At present, three grounding wires have been fixed in the three-phase grounding terminal of the grounding wire. When assembling the grounding wire, it is only necessary to connect the three-phase grounding wire and the clamp of the operating rod to fix it; however, a wrench must be used during the assembly of the grounding wire Unscrewing and tightening the nut to fix or loosen the grounding wire, this process not only has the potential safety hazard of the grounding wire being loosened and dropped, but also consume...

AI Technical Summary

Problems solved by technology

At present, three grounding wires have been fixed on the three-phase grounding terminal of the grounding wire. When assembling the grounding wire, it is only necessary to connect the three-phase grounding wire and the clamp of the operating rod to fix it; however, a wrench must be used during the assembly of the grounding wire Unscrew and tighten the nut to fix or loosen the grounding wire. This process not only has the potential safety hazard of the grounding wire loosening and falling, but also consumes a long time in the whole process and the labor intensity of the operator is high.

Therefore, the existing technology has the problems that the ground wire is easy to fall off and the assembly process is time-consuming and laborious.
