Cross-arm jig for replacing insulators with double-circuit steel pipe poles on the same tower

Abstract

The invention discloses a cross arm clamp for insulator replacement of a steel pipe pole of common-tower double-circuit lines. The cross arm clamp comprises a clamp body and is characterized in that the middle section of the clamp body is provided with two cross arm clamp seats, a wire grip clamp groove with an upward opening is formed in each of the two ends of the clamp body, a wire grip is hung in each wire grip clamp groove after being connected with an insulating pull rod and a wire lifting hook, and an insulator string can be replaced by tightening or loosening the wire grips. The cross arm clamp has the advantages that when the cross arm clamp is used, the problem of maintenance inconvenience caused by line design is solved; the cross arm clamp is simple to operate, time saving and labor saving, high in work efficiency, high in universality, free of special requirements on operating workers, low in operating worker number, simple in replacement, low in labor intensity, high in strength, light, high in safety, convenient to carry, short in operation time and capable of reducing line outage time and increasing electricity sales and line safety, and common hot-line operating workers can meet the maintenance process requirements.

Description

technical field [0001] The invention relates to a cross-arm jig for replacing hanging insulator strings with double-circuit steel pipe rods on the same tower, which is used for ground potential live work. Background technique [0002] With the continuous development of social economy, the public has higher and higher requirements for reliable power supply. Due to the small space occupied by the steel pipe pole, low investment, fast construction speed, beautiful and practical, it has been widely used in the construction of urban power grids in recent years. With the continuous increase of power lines and the gradual aging of some equipment, the daily maintenance and repair tasks of transmission lines are becoming more and more heavy. Due to the smooth surface of the steel pipe rod and the narrow operating space in the line design, the work task requirements of the live maintenance of the equipment are not fully considered, and limited by the design situation, the rod shape a...

AI Technical Summary

Problems solved by technology

Due to the smooth surface of the steel pipe rod and the narrow operating space in the line design, the work task requirements of the live maintenance of the equipment are not fully considered, and limited by the design situation, the rod shape and wire arrangement of the double-circuit steel pipe rod in the same tower are compared with the single-circuit angle steel tower. The line is more compact and the distance between the phases is also smaller, which makes it very difficult to replace the insulator string during live work on the steel pipe pole, which seriously affects the reliability and operation index of the line
