Ground-conductor energy release bar and ground-conductor spacer bar

Abstract

The invention provides a ground-conductor spacer bar. The ground-conductor spacer bar comprises a ground wire clip, a spacer bar insulator, an energy release bar, a connection fitting and a conductor spacer bar, which are connected in sequence, wherein the ground wire clip is movably connected with the spacer bar insulator, the connection fitting and the conductor spacer bar. The energy release bar includes a ground wire end fitting, a conductor end fitting, and an energy release mechanism, wherein the energy release mechanism includes a sleeve, a bushing, a guide rod and a spring; the ground wire end fitting is inserted into one end of the sleeve; a buffer cushion is placed in the sleeve at a position to which the ground wire end fitting is adhered; the other end of the sleeve is connected with the bushing having a contraction section and a guide rod moving port; an inner seal ring and an inner retainer ring are arranged between the contraction section and the sleeve; the guide rod with a guide block and a guide head is arranged in the bushing in a sliding manner, extends outside from the guide rod moving port, and is connected with the conductor fitting; and a spring is sheathed on the guide rod between the guide block and the inner retainer ring. The ground-conductor spacer bar provided by the invention can solve problem of tripping due to reduction of inter-wire safe distance and wave of the ground wire and the conductor caused by icing and deicing, thereby improving the operation security of the power transmission line.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to a spacer bar for ground wires and wires that can suppress galloping of ground wires and wires and ensure the insulation distance between ground wires and wires. Background technique [0002] In my country's high altitude, ice-covered and strong wind areas, the transmission lines of the power transmission system are not only affected by strong winds, but also affected by rain and snow in cold seasons. In rainy and snowy weather, the surface of the ground wire and the wire droops due to the thick ice layer and long ice hanging, and the distance between the ground wire and the wire part is reduced, which will cause the power transmission system to trip. The ice hanging is conductive, which further shortens the insulation distance between the ground wire and the wire below, and it is very easy to cause a flashover between the ground wire and the wire, causing a po...
