Bus-bar grounding rod for 10kV centrally-mounted switch cabinet

Abstract

The invention discloses a bus-bar grounding rod for a 10kV centrally-mounted switch cabinet. The invention aims to solve the problem of the inapplicability of other grounding rods to a switch cabinetdue to the narrow space of the switch cabinet. The bus-bar grounding rod comprises chuck connecting pieces; the chuck connecting pieces are two rod pieces which are symmetrically distributed; the twochuck connecting pieces are distributed to form a V-shape structure; a chuck part and a connecting part are connected so as to form the chuck connecting piece; a distance between the two chuck parts is larger than a distance between the two connecting parts; the top ends of the two chuck parts are provided with two contact ends respectively; a fixing piece is a T-shaped plate; the lower end of thefixing piece is connected with an insulating rod; the left end and right end of the upper portion of the fixing piece are in pin joint with the upper ends of the two connecting parts respectively; two ends of a spring are fixedly connected with the middles of the two connecting parts respectively; the two connecting parts each are in pin joint with one end of a movable connecting sheet; the otherends of the movable connecting sheets are in pin joint with each other; the other ends of the two movable connecting sheets are connected with one end of an insulating pull rope; the insulating pullrope penetrates through the insulating rod; the other end of the insulating pull rope is connected to a handle; and the handle can be pulled out along the insulating rod. The bus-bar grounding rod isconvenient and safe to operate.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a grounding rod for a bus bar of a 10kV mid-mounted switch cabinet. Background technique [0002] For now, for the 10kV power distribution room of the substation, it is often necessary to overhaul the 10kV bus due to equipment modification and expansion. It is larger and uses many types of grounding rods, but its versatility is poor and cannot meet the safety requirements of on-site work. For example, the "double tongue hook type" grounding rod is very suitable for grounding outdoor wires, wire lugs, etc., but not suitable for grounding aluminum bars, etc., and the "tweezers" grounding rod is very suitable for grounding bodies such as aluminum bars , but it is only applicable to the line maintenance situation, and the relevant safety measures cannot be satisfied during the maintenance process of the 10kV busbar. At the same time, for a place with a narrow space such as ...
