Description

A grounding clamp for bus bridge grounding

technical field

The utility model relates to the technical field of grounding safety, in particular to a grounding clip used for grounding of a bus bridge.

Background technique

At present, the grounding clamp used for grounding the busbar bridge in the substation is a crimping type. According to the "State Grid Corporation Electricity Safety Work Regulations" (substation part), the grounding wire should be connected to the grounding end first, and then to the conductor end. When the busbar bridge is grounded, after the grounding wire and the grounding end are connected and fixed, the opening of the traditional grounding wire clamp (consisting of the metal frame of the grounding wire clamp and the movable clamp) is connected to the conductor end, and the rotating insulating rod is used to move the movable clamp of the grounding wire up and down. In order to realize the connection and fixation between the grounding clamp and the conductor end. The traditional grounding clamps used for busbar bridge grounding have the following problems during the operation process: (1) The traditional grounding wire grounding operation takes a long time. The opening adjustment is relatively large, but the large opening will cause the time for the rotating insulating rod to move up and down to move the ground wire clamp movable clamp to fix the conductor end, thereby increasing the time for grounding operations and increasing the labor intensity of the staff; (2) Traditional ground wires There is a risk that the clamp is not firmly connected to the bus bridge. When the rotating insulating rod moves up and down and the movable clamp is fixed to connect the conductor end, under the influence of the multi-strand annealed copper wire's own gravity, when the grounding clamp is connected to the A and C two-phase bus bridge It is easy to fall off; at the same time, when the insulating rod is rotated, the metal frame of the grounding wire clamp rotates together, so that the opening of the grounding wire clamp cannot be crimped vertically with the conductor end.

Aiming at the problems in the related technologies, no effective solution has been proposed yet.
