Tool for live replacement of over-voltage protection device of distribution line

Abstract

The invention relates to a tool for the live replacement of an over-voltage protection device of a distribution line. The distribution line comprises a conducting wire, a cross arm, an insulator and the over-voltage protection device, wherein the over-voltage protection device and the insulator are arranged in parallel between the conducting wire and the cross arm. The tool comprises an insulating bracket and an insulating operating rod. The insulating bracket comprises a bracket body and a fastening component. The lower end of the bracket body is fixed on the cross arm of the line through the fastening component, and the upper end of the bracket body jacks the conducting wire. The insulating operating rod comprises a chuck, a fastening bolt, an upper cover and a lower cover. One end of the chuck penetrates through the upper cover, and then is fixed. The lower cover is connected with the upper cover through the fastening bolt. After the bracket body jacks the conducting wire, the chuck clamps the over-voltage protection device. Compared with the prior art, the tool has the advantages of ensuring live work, shortening interruption duration, increasing a power supply volume, and the like.

Description

technical field [0001] The invention relates to a tool in the field of electrical construction, in particular to a tool for live replacement of an overvoltage protection device for a power distribution line. Background technique [0002] Nowadays, as the overhead distribution lines are gradually insulated, it solves the corridor and safety problems that bare wires cannot solve, but the problem of lightning disconnection is very prominent. The overvoltage protection device is a very effective device to avoid lightning tripping and lightning disconnection of the overhead insulated conductors of the distribution network. However, the device will inevitably fail and be damaged during use. At present, how to replace the damaged There is no better solution for the overvoltage protection device and how to keep the wires in contact with other substances in the workspace during the replacement process. Contents of the invention [0003] The purpose of the present invention is to p...
