Operation tool for tightening 10KV high voltage power distribution line porcelain insulator

Abstract

The invention relates to an operation tool for tightening a 10KV high voltage power distribution line porcelain insulator. The operation tool is used for the hot-line tightening operation of a medium-phase porcelain insulator. The operation tool comprises an insulation operation rod, a nut sleeve tube and a gear disc, wherein the gear disc comprises a first gear and a second gear, the diameter of the first gear is smaller than the diameter of the second gear, the centers of the first gear and the second gear are respectively provided with a key pin connecting head opening, the upper end of the insulation operation rod is provided with a first key pin connecting head, the first key pin connecting head is connected with the gear disc through the key pin connecting head opening of the first gear, a second key pin connecting head is inserted into the key pin connecting head opening of the second gear, the nut sleeve tube is arranged on the second key pin connecting head, and the bottom end of the insulation operation rod is provided with an insulation rotary handle. The operation tool has the advantages that the tightening operation of the medium-phase porcelain insulator is easily realized, and the problem that the existing operation tool cannot completely extend into the gap between a heightening bracket and a transverse beam to complete the tightening operation of the medium-phase porcelain insulator is solved.

Description

technical field [0001] The invention relates to a 10KV high-voltage power distribution line, in particular to an operating tool for fastening porcelain vases of the 10KV high-voltage power distribution line. Background technique [0002] In 10KV overhead distribution lines, pin insulators (a type of porcelain bottle) are usually used to fix the wires, and the pin insulators are fixed on the supporting cross-arm through bolts and nuts. During the operation of the 10KV overhead distribution line, the bolts are easily corroded due to the influence of rain and humid air, and the influence of wind will cause the mechanical vibration of the wire to resonate, which will easily lead to the loosening of the bolts and nuts of the insulator, and even the nuts fall off. Once the phenomenon of loosening or falling off occurs, the wires are likely to fly out of the porcelain bottle, resulting in phase-to-phase short circuit or ground short circuit accidents (especially bare wires), which...

Problems solved by technology

[0005] The object of the present invention is to provide an operation tool for fastening porcelain bottles of 10KV high-voltage power distribution lines. The operation tool adds a gear plate to the original operation tool to realize the fastening work of the middle-phase porcelain bottle, so as to solve the problem of The distance between the raised bracket and the cross-arm of the high-voltage distribution line is too small, so that the existing operating tools cannot fully penetrate into the gap between the two, and the problem of fastening the medium-phase porcelain bottle is completed
