Abstract

The invention discloses an operation structure for ground potential live-line lapping operation, which comprises a wire clamp assembly, a support rod assembly and a sleeve assembly. The wire clamp assembly is supported on the support rod assembly. The sleeve assembly is located below the wire clamp assembly. The wire clamp assembly comprises an upper clamping plate and a lower clamping plate. Boththe upper clamping plate and the lower clamping plate are of a square structure, two or three studs are fixedly connected to the lower portion of the upper clamping plate, the lower clamping plate isarranged on the studs in a sleeving mode and fixed through gaskets and nuts, arc-shaped grooves which are symmetrical up and down are formed in the opposite faces of the upper clamping plate and thelower clamping plate, and wires to be connected are located in the grooves. The upper and lower cross rods are arranged at the top end of an insulating rod, the wire clamp can be positioned between the cross rods, and then the wire to be connected passes through the wire clamp to be fixedly connected, so that live-line lapping can be carried out, and a very good effect is achieved.

Description
