Abstract

The invention discloses a fireproof power fuse capable of conveniently replacing a fuse wire. The fireproof power fuse comprises a shell, power connection pipes and fuse wires, wherein the two ends ofthe shell are both fixedly connected with the power connection pipes which are horizontally distributed, the inner sides of the two sets of power connection pipes are fixedly connected with power connection blocks which are communicated with the shell, the inner side of the shell is rotatably connected with a rotary disc, and the inner side of the rotary disc is provided with the four sets of fuse wires which are distributed in an annular array mode. According to the present invention, a rotary disc type wire changing structure is adopted, so that convenient replacement of a fuse wire can berealized, the workload of an operator is reduced, and fuse wire replacement convenience is improved so as to facilitate the actual operation and use of the power fuse; and the fuse wire can be coveredand extinguished when the temperature of the fuse wire is abnormal or open fire is generated due to the adoption of the covering type fire extinguishing structure, so that the burning phenomenon of the fuse is reduced so as to improve the use safety of the power fuse wire.

Description

technical field [0001] The invention relates to the technical field of power fuses, in particular to a fireproof power fuse which is convenient for replacing fuses. 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. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment, as short circuit and overcurrent protectors, and are one of the most commonly used protection devices. However, the existing power fuses still have disadvantages: First, most of them use a single insurance structure. When the fuse ...
