Abstract

The invention relates to the technical field of electric power grids,and discloses an open fuse with a fusible core easy to replace. The open fuse comprises a shell,wherein the left end and the rightend of the shell are fixedly provided with a wire outlet port and a wire inlet port respectively,a rotating disc is hinged to the interior of the shell,and a rotating shaft matched with the shell is installed on the rotating disc; a rotating handle is arranged at the tail end of the rotating shaft,and detachable movable ceramic units are inserted in the upper portion of the rotating disc in an array at equal intervals. According to the open fuse,power can be quickly recovered through the rotating disc and a plurality of replaceable fuse wires installed on the rotating disc; besides,the time for replacing the fuse wires can not influence the electric power recovery speed; meanwhile,the replaceable fuse wire area is isolated from an internal circuit,and electric power accidents are avoided during replacement. The fuse can also be used as a switch blade,and can directly skip the fuse wires and be connected with the circuit so that various use occasions and emergency states can be effectively dealt with,the application range is expanded,and practicability is improved.

Description

technical field

[0001] The invention relates to the technical field of power grids, in particular to an open fuse that is easy to replace a melting core. Background technique

[0002] A fuse is an electrical appliance that uses the heat generated by overcurrent to fuse itself and disconnect the circuit. Because of its simple structure and high reliability, it is widely used in high and low voltage power distribution systems and control systems as short circuit and overcurrent protectors. Existing fuses are mainly divided into closed and open structures. The closed structure is completely sealed inside and can only be used for one-time use, while the open fuse can be replaced with a new fuse, so it can be used repeatedly. But now The replacement process of some open fuses is still very complicated and takes a lot of time, which is not conducive to the rapid recovery of power.

[0003] Such problems can be solved by inventing a new type of open fuse that can quickly replace ...
