Abstract

The invention discloses a rotary disc wire replacement type power fuse. The fuse comprises a shell, a front cover, fuse wires and a power connection cylinder; the front cover is installed at the frontend of the shell; a rotary disc is rotatably connected to the inner side of the shell; and the six fuse wires are annularly installed on the outer portion of the rotary disc at equal angles; a supporting rotary column penetrating through the front cover is fixedly connected to the middle of the front end of the rotary disc; a rotary buckle attached to the front cover is installed at the front endof the supporting rotary column. According to the rotary disc wire replacement type power fuse of the invention, a rotary disc type fuse replacement structure is adopted, so that built-in replacementprocessing of the fuse can be carried out through external operation of the power fuse, the workload of an operator is reduced, the convenience of fuse replacement processing is improved, and the efficiency of power construction operation is improved; and a photoelectric reminding structure is adopted, and therefore, an operator can conveniently observe and process the working state of the fuse wires, so that the functionality of the power fuse is improved, and meanwhile, the use safety of the power fuse is also improved.

Description

technical field [0001] The invention relates to the technical field of power fuses, in particular to a rotary wire change type power fuse. Background technique [0002] A power fuse is one of the fuses, which refers to an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. However, there are still deficiencies in the existing power fuses: most of the fuses are fixed in the housing by welding or fasteners. The replacement of the fuse is installed in the shell, and the whole replacement process is time-consuming and laborious, which is difficult to meet the daily operation and use of power erection. Contents of the invention [0003] The purpose of ...
