Description
Technical Field
[0001] The utility model relates to the technical field of wiring ground clamps, in particular to a busbar grounding wire clamp. Background Art
[0002] Busbar is the name of the conductive material on the power distribution equipment. It is made of flat copper. There is no insulating layer on the outside of the busbar. The outside is painted with color paint indicating the phase sequence. The grounding wire is used for temporary maintenance. The clamped busbar is used to hold the residual current in the grounding wire, thereby ensuring the safety of the staff during power outages for maintenance.
[0003] The current operating method is that the operator rotates the insulating rod to clamp the lower conductor. The fixed part often detaches from the copper busbar as it rotates, and the success rate of one-time tightening is very low. It usually takes more than 10 minutes to install three phases, and most of the time is invalid operation time. In addition, the busbar grounding clamp needs to repeatedly rotate the metal rod when fixing the line so that the metal block can clamp the line. The fixation is very inconvenient and the process is also time-consuming. In addition, the wire clamp has no corresponding blocking measures after clamping a line, which may cause other lines to enter the inside of the wire clamp or the bottom handle to collide.
