A ground wire assembly

Abstract

The invention discloses a ground wire assembly comprising a main rod body and an auxiliary rod body which are arranged in parallel. The top end of the main rod body is provided with a fixing head restraint matched with a wiring terminal. The top end of the auxiliary rod body is provided with a movable head restraint clamped and matched with the fixing head restraint. A guiding aperture is arranged in the fixing head restraint along an axial direction of the main rod body. The tail end of the movable head restraint is movably inserted in the guiding aperture and is in hinged connection with the auxiliary rod body. The middle portion of the main rod body is provided with an adjusting gear in a rotatable mode. The axis of the adjusting gear is perpendicular to the axis of the main rod body. A matched surface between the tail end of the auxiliary rod body and the main rod body is provided with a tooth bar engaged with the adjusting gear in a matched mode. The connection structure of the ground wire assembly is safe and reliable, and the operation process is simple to perform.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for erection and maintenance of power transmission and transformation lines, in particular to a ground wire assembly. Background technique [0002] In the daily operation and maintenance of substations, most operations require power outages, so adding ground wires to equipment that has been powered off is one of the common operations in substation operation and maintenance. [0003] In the current actual operation process, the grounding wires used in the existing substations are of the turnbuckle type. When the grounding wire is added, the operator must forcefully hold the grounding wire to the hanging point to perform the turnbuckle, otherwise It will lead to incomplete contact between the hanging grounding wire and the grounding point, so that the grounding resistance does not meet the requirements, and improper force may cause the grounding wire terminal to slip, posing a threat to...

[0003] In the current actual operation process, the grounding wires used in the existing substations are of the turnbuckle type. When the grounding wire is added, the operator must forcefully hold the grounding wire to the hanging point to perform the turnbuckle, otherwise It will lead to incomplete contact between the hanging grounding wire and the grounding point, so that the grounding resistance does not meet the requirements, and improper force may cause the grounding wire terminal to slip, posing a threat to the personal safety of the staff. At the same time, the operator is wearing insulating gloves. It is very inconvenient to rotate the grounding wire under the condition of
