Live working phase spacing control device on equipotential wire

Abstract

The invention discloses a live working phase spacing control device on an equipotential wire. The live working phase spacing control device comprises a wire fixing device and an insulation ruler which are connected, wherein the wire fixing device comprises an insulation yoke plate and two wire fixing grooves which are detachably formed in the insulation yoke plate and are used for fixing a sub-busbar of a lower wire; each wire fixing groove comprises a mounting base, a pulley and a self-locking protection key; the pulley is arranged in the mounting base in a rotating manner; the self-locking protection key is detachably mounted on the mounting base and used for preventing a wire from falling; the insulation ruler is provided with scales for marking length. When an operator walks on the wire by using the live working phase spacing control device, the lower wire of the wire, on which the operator walks, changes according to the sag change of the wire on which the operator walks, can guarantee a sufficient safety distance between the operator and the lower wire, and is simple and convenient to use and safe to operate, and meanwhile, as the self-locking protection key is arranged on the mounting base, the sub-busbar of the lower wire can be effectively locked, the wire is prevented from falling when the device moves, thus the device is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of live work on power grids and transmission lines, in particular to a control device for phase-to-phase distance of live work on equipotential conductors. Background technique [0002] With the development of society and economy, the society's demand for electric power is increasing, which promotes the continuous expansion of the grid scale. As the current main mode of power transmission, overhead line transmission is also increasing the scale of the line. With the acceleration of urbanization, the land resources are becoming more and more tense. The commonly used typical angle steel towers occupy a wide line channel and the towers are large, which cannot adapt to the current situation of land resources shortage in economically developed areas. However, if steel pipe poles are used, although it can meet the requirements of reducing the occupied area, the steel pipe pole lines have higher requirements than i...

AI Technical Summary

Problems solved by technology

The conductors of each phase of the narrow base tower are erected compactly. When personnel are required to equipotentially enter the gear for maintenance work, the weight of the maintenance personnel plus the weight of materials, tools, etc. will cause the sag of the phase conductors to become larger, which may lead to failure to meet the equipotential requirements. Requirements of personnel for the safety distance of adjacent conductors
