Fixed-type grounding hook device

Abstract

The invention discloses a fixed-type grounding hook device which is characterized by including two locking buckles which are arranged to be face to face. Upper parts and lower parts of the two locking buckles are provided with a wire installation groove and a hook installation groove respectively. A hook is installed in the hook installation groove. The two locking buckles are fixedly connected through bolts and nuts. The fixed-type grounding hook device is simple in structure, convenient to use, capable of helping maintenance personnel to find rapidly a grounding point of an high-voltage insulating wire and increasing firmness and stability of connection of a grounding wire clamp and the high-voltage insulating wire so that comparatively large safety guarantee is provided to the maintenance work personnel. The fixed-type grounding hook device is mainly used for auxiliary connection of a wire and a grounding wire clamp of a 6-10 kV high-voltage insulating circuit in a transformer substation.

Description

technical field [0001] The invention relates to an auxiliary device of a grounding clamp used for grounding a conductor during maintenance of a 6-10kV high-voltage insulated line in a substation, in particular to a fixed grounding hook. Background technique [0002] The substation is an important production site in the process of electric energy transmission. The equipment in the substation needs regular maintenance or troubleshooting, which requires power failure and reliable grounding of the overhauled equipment, so as to protect the safety of the personnel working on the equipment. The grounding needs to use special The grounding wire is generally equipped with a special clamp. [0003] The traditional grounding method is to hang the clamp on the grounding wire directly on the exposed high-voltage wire, but the bare wire is easily short-circuited and grounded due to the influence of the external environment. In recent years, 6-10kV high-voltage lines have been gradually ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that operators often cannot accurately hang the grounding wire clamp on the grounding point of the high-voltage insulated wire during the maintenance of the current high-voltage insulated wire, the grounding wire clip is easy to slide to the part where the high-voltage insulated wire has insulation, and the grounding is not firm.
