Problems solved by technology

[0002] At present, in the high-voltage power grids of various industrial and mining enterprises, the line protection devices all use high-voltage drop fuses. Once the high-voltage drop fuses fail, the entire grid must be powered off for maintenance. This will cause huge damage to enterprises that do not allow intermittent power supply. economic loss

Abstract

The invention provides a high voltage distribution fuse, mainly comprising a distribution rubber-sheathed fuse, two copper conductive contact boards, insulation columns, an upper hanging ring, a lower hanging ring, a pulling spring and an insulation bushing. The insulation columns are respectively arranged at the two ends of the copper conductive contact board. The insulation columns which correspond to each other from bottom to top are hooked by the pulling spring to be connected. The outer part of the pulling spring is sleeved with the insulation bushing. Two ends of the distribution rubber-sheathed fuse are respectively connected with the ends of the upper and lower copper conductive contact boards to form a distribution branch. The invention is in parallel connection with the wiring screws at the two ends of a failed high voltage drop-out fuse and can displace the a failed high voltage drop-out fuse to work, so as to guarantee a constant work of the grid. The design of the invention is novel, the structure is simple, the operation is safe and easy and the use is convenient.

Description

Technical field: [0001] The invention relates to a high-voltage electric line protection device, in particular to a high-voltage shunt fuse. Background technique: [0002] At present, in the high-voltage power grids of various industrial and mining enterprises, the line protection devices all use high-voltage drop fuses. Once the high-voltage drop fuses fail, the entire grid must be powered off for maintenance. This will cause huge damage to enterprises that do not allow intermittent power supply. economic loss. Invention content: [0003] The object of the present invention is to provide a high voltage shunt fuse. When the high-voltage drop-out fuse fails, it can quickly replace the work of the high-voltage drop-out fuse to ensure the normal power supply of the grid. It not only has the same fusing protection function as the conventional high-voltage drop-out fuse, but also has a simple structure, safe operation and convenient use. [0004] A high-voltage shunt fuse, wh...
