Device for replacing linear single-string insulators by remote operations and application method of device

Abstract

The invention discloses a device for replacing linear single-string insulators. The device comprises a fixed frame and a pulley connected below the fixed frame, the fixed frame is fixed to a cross arm, a pole end of the cross arm is connected with a worm and gear device, the worm and gear device drives the pulley to move along the fixed frame through a sheaves and lifting insulation ropes, the front end of the pulley is lifted upwardly obliquely through the sheaves and the lifting insulation ropes to drag an insulator string so as to enable connection load between the upper end of the insulator string and the cross arm to be transferred onto a clamping plate of the pulley, and connection load between the lower end of the insulator string and a wire is transferred onto the fixed frame through hooks and a pulley component, thereby convenience and quickness in demounting of the insulator string are achieved. The invention further discloses a method of using the device for replacing the linear single-string insulators. By means of cooperation of a pole operator and a ground operator, the insulators are replaced by indirect operations of the operators adopting ground potential, replacement operations of the insulator strings are all completed at the pole end and away from the insulator strings, and accordingly safety and high efficiency are achieved.

Description

technical field [0001] The invention relates to a power transmission line of a straight single-string insulator, in particular to a device for remote operation and replacement of a straight single-string insulator on a power transmission line and an application method thereof. Background technique [0002] The current replacement of straight line single-string insulators generally requires one operator to mount the pulley block or fixture to the suspension point of the conductor, and another operator to climb to the conductor through a flat or soft ladder, and the two operators cooperate to install the tool. Transfer loads, replace insulators, remove tools and more to complete the job. However, the existing compact lines, multi-circuit transmission lines on the same tower, and multi-circuit compact lines on the same tower generally have the characteristics of high pole towers, various types of pole towers, small distances between cross-arms and phase-to-phase clearances, and...

Problems solved by technology

However, the existing compact lines, multi-circuit transmission lines on the same tower, and multi-circuit compact lines on the same tower generally have the characteristics of high towers, various types of towers, small distances between cross-arms and phase-to-phase clearances, and relatively complicated conductor arrangements. The characteristic of multi-circuit transmission lines on the same tower is particularly obvious, so that the safety distance cannot meet the requirements of live work, and live work cannot be carried out by using existing methods
