10kV high-voltage fuse dismounting and mounting tool

Abstract

The invention discloses a 10kV high-voltage fuse dismounting and mounting tool. The 10kV high-voltage fuse dismounting and mounting tool comprises a clamping body and an insulating rod; the insulating rod comprises an inner cylinder and an outer cylinder, the outer cylinder sleeves the inner cylinder in a sliding manner, one end of the inner cylinder is limited in the outer cylinder, and the other end of the inner cylinder is exposed out of the top end of the outer cylinder; and the clamping body is fixedly connected with the top end of the outer cylinder, a clamping space used for clamping a high-voltage fuse is formed between the clamping body and the exposed end of the inner cylinder, and in the process that the outer cylinder slides relative to the inner cylinder, the clamping body can move relatively along with the outer cylinder, so that the clamping space can be gradually increased or reduced. According to the 10kV high-voltage fuse dismounting and mounting tool, the size of the clamping space can be adjusted by controlling the relative sliding of the outer cylinder and the inner cylinder, so that the clamping space is matched with the actual size of the high-voltage fuse, and the safety and convenience of dismounting and mounting of the high-voltage fuse are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a tool for disassembling and assembling a 10kV high-voltage fuse. Background technique [0002] High-voltage fuses, also known as drop-out fuses and drop-out fuses, are the most commonly used short-circuit protection switches for branch lines of 10kV distribution lines and distribution transformers. It is installed on the branch line of 10kV distribution line. Because it has an obvious disconnection point and has the function of isolating switch, it creates a safe working environment for the maintenance line and equipment, and increases the maintenance installation. It has been popularized in 10kV distribution lines and distribution transformers. [0003] As an important component for measuring the PT interval of the 10kV busbar, it is often necessary to remove the 10kV high-voltage fuse in order to prevent secondary reverse power transmission during busbar power outages ...

AI Technical Summary

Problems solved by technology

[0005] 1) During the disassembly and assembly of 10kV high-voltage fuses, the safety distance between the operation duty personnel of the substation and the static contact of the PT knife switch is often less than 0.7 meters, which poses a safety hazard

[0006] 2) When the 10kV bus PT stops the power transmission operation, if there is a wrong operation in which the operation sequence is reversed once or twice, the second ti
