Abstract

The invention discloses a strain insulator exchange tool, which comprises a first insulated end plate, a second insulated end plate, a line blocking device, at least two clamping plates and at least two insulated pull rods, wherein the at least two insulated pull rods can stretch; a control handle for controlling stretching is arranged on each insulated pull rod; the first insulated end plate and the second insulated end plate are arranged at two ends of the insulated pull rods respectively; the first insulated end plate and the second insulated end plate and the at least two insulated pull rods form an insulated line tightening frame; the clamping plates are arranged on the at least two insulated pull rods; recessed arc gaps for supporting a strain insulator is formed in the clamping plates; connecting rods are arranged between the adjacent two clamping plates in a penetrating manner; the at least two clamping plates and the connecting rods can form a bracket capable of putting the insulator; and the line blocking device is arranged on the first insulated end plate. The strain insulator exchange tool has the characteristics that the strain insulator is exchanged in an electrified manner, and the strain insulator exchange tool is convenient to operate, high in safety and the like.

Description

technical field [0001] The invention relates to the technical field of power system maintenance, in particular to a tension insulator replacement tool. Background technique [0002] At present, in the 10KV power supply line, most of the defective insulators are replaced by the power-off type, that is, maintenance and replacement are carried out under the condition of power failure, which will cause inconvenience to the enterprises, institutions and residents within the power supply range of the line. It also adversely affects economic and social benefits. Contents of the invention [0003] Based on this, the purpose of the present invention is to overcome the defects of the prior art and provide a tension insulator replacement tool, which has the characteristics of live replacement of tension insulators, easy operation and high safety. [0004] Its technical scheme is as follows: [0005] A strain insulator replacement tool, comprising a first insulating end plate, a sec...
