Shifting device for two-circuit hot-line work of transmission line

Abstract

The invention discloses a shifting device for two-circuit hot-line work of a transmission line. The device comprises an insulating supporting rod and a fixed adjustment seat thereof, wherein the insulating supporting rod is movably hinged with the fixed adjustment seat; a connecting piece is arranged at the upper end of the insulating supporting rod; and the connecting piece is respectively connected with a pulley block and a hanging ladder. The insulating supporting rod of which the position can be adjusted in horizontal direction and vertical direction is arranged independently and fixedly outside a working position. Compared with the newly developed same-pole tower compact two-circuit and multi-circuit tower type which has the characteristics of small safety distance, non-enough combined gap or high overlapping difficulty, the invention has the advantages that: an equipotential worker can be quite conveniently and accurately shifted to a required working position; a novel auxiliarydevice is provided for equipotential operation of a power system; and the device is particularly applicable to operation such as replacement of a damper, repair of a lead and heating treatment of an anti-tension drainage wire joint on the same-pole tower two-circuit (multi-circuit) tower.

Description

technical field [0001] The invention belongs to an auxiliary tool for live work of electric facilities, in particular to a transfer-in device for safely implementing equipotential live work with dual circuits of the same pole and tower for 110-220kV transmission lines. Background technique [0002] With the promotion of condition-based maintenance of power transmission and transformation equipment in the power system, the routine maintenance and repair of transmission lines generally adopts the equipotential operation method, that is, the operator is sent to the equipotential operation site with the help of the relevant transfer device, and the operation is completed. Related daily maintenance and inspection work. At present, there are several ways for operators to enter the equipotential work site: horizontal entry along the insulating hard ladder, swinging in the hanging basket, swinging in the soft and hard ladder, or horizontal entry along the slide rail. However, in r...
