Abstract

The invention discloses a turntable wire-changing electric fuse, which comprises a housing, a front cover, a fuse and a torch. , the outside of the rotating disc is arranged with six fuses at an equal angle in a ring shape, and the middle part of the front end of the rotating disc is fixedly connected with a supporting rotating column that penetrates the front cover, and the front end of the supporting rotating column is installed with the front cover. fitted turnbuckle. In the present invention, first of all, the rotating disk type wire replacement structure is adopted, and the built-in replacement process of the fuse can be performed by operating outside the power fuse, which reduces the workload of the operator and improves the convenience of the fuse replacement process, thereby It improves the efficiency of power construction operations. Secondly, it is equipped with a photoelectric reminder structure, which is convenient for operators to observe and process the working status of the fuse. It not only improves the functionality of the power fuse, but also improves the safety of the use of the power fuse. .

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 ...
