Problems solved by technology

[0004] The insulator is installed on the cross arm of the pole. Usually, the maintenance personnel need to climb the pole for maintenance to fasten the insulator. The line must be powered off when the pole is overhauled. The work ticket and operation ticket need to be filled in for the maintenance of the line. Not only the work intensity is high, but also the efficiency Low, there are potential safety hazards, and the operation is cumbersome

Embodiment Construction

[0021] An insulator fastening wrench, comprising: an insulating pull rod 1 and a fastening head 2, the fastening head 2 is connected to the top of the insulating pull rod 1, and an insulating envelope 4 is provided at the connecting end of the insulating pull rod 1 and the fastening head 2.

[0022] The fastening head 2 is an inner hexagon.

[0023] The length of the insulating pull rod is 4-6 meters.

[0024] The insulating pull rod 1 is formed by connecting at least two sections of insulating operating rods 3 .

[0025] The insulating envelope 3 is made of silicone rubber insulating material, which can effectively avoid being broken down under high-voltage conditions, prevent personal injury accidents, and is suitable for maintenance of lines of various voltage levels.

[0026] When in use, the three sections of insulating operating rods 3 are connected together to form an insulating pull rod 1, and the fastening head 2 is aligned with the bolts on the insulator to fasten t...

Abstract

The invention discloses an insulator fastening lever, and belongs to the technical field of electric auxiliary tools. The insulator fastening lever comprises an insulating draw bar and a fastening head. The fastening head is connected to the top of the insulating draw bar, and an insulating sleeve is arranged at a joint end of the insulating draw bar and the fastening head; the fastening head is internally hexagonal; the length of the insulating draw bar ranges from 4 meters to 6 meters; at least two insulating operating bars are connected with each other to form the insulating draw bar. The insulator fastening lever has the advantages that the insulator fastening lever can be operated under an electrified condition, long-time power failure due to defects of equipment is reduced, the maintenance time is shortened, the power supply capacity is improved, social and economic benefits are increased, normal power supply of the equipment is guaranteed, the work efficiency and the power supply reliability of the equipment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of power auxiliary tools, in particular to an insulator fastening wrench. Background technique [0002] In overhead transmission lines, insulators are often used as insulation controls. In the past, they were mostly used for utility poles, and gradually developed in high-voltage wire connection towers. They are used to increase creepage distances, support busbars and live conductors, and connect live conductors or conductors There is sufficient distance and insulation between the earth. An insulator is a special insulating control, usually made of glass or ceramics, with sufficient electrical insulation strength and moisture resistance. [0003] As a special insulation control, insulators play a very important role in overhead transmission lines, but in power lines, due to years of operation, the nuts at the bottom of insulators often loosen and cause insulators to tilt, and in severe cases they will fall o...
