Grounding device for jp cabinet

Abstract

The invention discloses a grounding device for a JP cabinet, aiming to provide a grounding device that can not only hang the grounding wire in the JP cabinet, but also provide a suitable grounding position to facilitate the hanging of the grounding wire; A grounding device for JP cabinets that effectively prevents the grounding clip from falling off easily. It includes a clamping assembly. The clamping assembly includes a clamping head and a locking stud. The clamping head is provided with a clamping groove and a bolt hole communicating with the clamping groove. The stud section, the clamping section and the locking head, the stud section is matched with the bolt hole; the locking device, the locking device includes an insulating operating rod and a sleeve arranged at one end of the insulating operating rod, and the sleeve is used for connecting with the locking head Cooperate to tighten or loosen the locking stud; the grounding wire assembly, the grounding wire assembly includes a grounding wire clamp and a grounding wire electrically connected to the grounding wire clamp; a sliding locking type misuse prevention device.

Description

Technical field [0001] The invention relates to a grounding device, in particular to a grounding device for JP cabinets. technical background [0002] JP cabinet refers to JP integrated distribution box, which is a kind of integrated control box integrating electric energy distribution, measurement, protection, control and reactive power compensation. The grounding line is the line directly connected to the earth, which can also be called the safe return line. The grounding line in the power system is an important tool to ensure the safety of the staff when voltage unexpectedly appears on the equipment and lines that have been cut off. As there is no grounding device in JP cabinet itself, it is necessary to hang a grounding wire in JP cabinet during maintenance to ensure the safety of operators. At present, the grounding wire (grounding wire clamp at one end) hung in JP cabinet is generally installed at the outlet bus bar of main knife in JP cabinet, that is, the grounding wire c...

AI Technical Summary

Problems solved by technology

At present, the grounding wire (with a grounding wire clamp at one end of the grounding wire) hung in the JP cabinet is generally installed at the main switch outlet busbar in the JP cabinet, that is, the grounding wire clamp is directly clamped on the busbar. In this way, although it can be realized Grounding, but the handle of the grounding clamp often protrudes out of the cabinet door, and it is easy to cause the cabinet door to squeeze the handle of the grounding clamp when the cabinet door is closed (for example, accidentally touching the cabinet door to make the door close), causing the wire clip shedding problem

On the other hand, due to the small distance between the outlet busbars of the main switch, it is often impossible to find a suitable place for the clamping of the grounding wire. In this way, although grounding can be achieved, the clamping stability of the grounding clamp is not good, and it is easy to cause the problem of the clamp falling off
