Problems solved by technology

Due to the deflection of the wires of the straight corner tower by 0°-20°, the insulator string is subjected to a horizontal load and deflects, and the hanging point of the wires of the insulators will cross the farthest end of the cross arm. At this time, in the traditional straight tower operation method, the tower Workers cannot use ropes to pull equipotential workers and insulators to conductors

Abstract

The invention discloses a device and a method for replacing an insulator string of a straight corner tower in a hot-line work mode. The device comprises a replacement tool (1) which is used for fixing and transferring the load of an insulator string to be replaced. The device is characterized by also comprising an insulating cross arm (2), an insulating pulley block (3), a plurality of insulating hauling ropes (4) and an insulating basket (5). The method comprises the following steps: mounting the insulating cross arm (2) and the insulating pulley block (3); mounting the replacement tool (1); allowing the insulating hauling ropes (4) to penetrate through the insulating pulley block (3) and mounting the insulating basket (5); hauling the insulating hauling ropes (4) to ensure that the insulating basket (5) and an equal potential operator in the insulating basket (5) enter an equal potential, and the like. According to the device and the method for replacing the insulator string of the straight corner power in the hot-line work mode, which are disclosed by the invention, the device is simple in structure, reasonable in design, safe, reliable, free of influence from deflection of the insulator string and strong in university, and the device and the method are suitable for being widely popularized and applied.

Description

technical field [0001] The invention relates to a device and method for live replacement of straight-line corner tower insulator strings, in particular to a device and method capable of live replacement of 500kV line straight-corner tower insulator strings of different tower shapes, belonging to the technical field of power line maintenance. Background technique [0002] Insulators are an indispensable electrical component in the process of power transmission. They are mainly used on transmission line towers to carry the load of the wires and maintain electrical insulation between the wires and the tower itself. Since the insulator works in the outdoor environment for a long time, it is more prone to defects. Due to the deflection of the wires of the straight corner tower by 0°-20°, the insulator string is subjected to a horizontal load and deflects, and the hanging point of the wires of the insulators will cross the farthest end of the cross arm. At this time, in the tradit...
