Abstract

The invention discloses a fireproof electric fuse which is easy to replace the fuse, which comprises a casing, a connection pipe and a fuse. The inner side of the electric tube is fixedly connected with a connecting block which communicates with the casing, and the inner side of the casing is rotatably connected with a turntable, and the inner side of the turntable is installed with four groups of fuses arranged in a circular array. In the present invention, first of all, the rotating disk type wire replacement structure is adopted, which can realize the convenient replacement of the fuse, reduces the workload of the operator, improves the convenience of the replacement of the fuse, and thus facilitates the actual operation and use of the power fuse. Secondly, The cover-type fire extinguishing structure is adopted, and the fuse can be covered and extinguished when the temperature of the fuse is abnormal or an open flame is generated, which reduces the occurrence of the burnout of the fuse, thereby improving the safety of the use of the electric fuse.

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, fuses 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 fus...
