Abstract

The invention discloses a self-recovery fuse realized by using liquid metal and a circuit, and belongs to the technical field of electrics.The self-recovery fuse comprises a shell, a coil assembly, two U-shaped magnets and a quartz electric arc tube, the coil assembly, the U-shaped magnets and the quartz electric arc tube are all located in the shell, the number of the U-shaped magnets is two, the two U-shaped magnets are located on the two sides of the quartz electric arc tube respectively, and each U-shaped magnet is wound with a coil group. According to the invention, self-recovery of the fuse can be realized; the self-recovery fuse is suitable for a high-power fuse; the electric arc can be blown out; and the adjusting range is wide by using the variable resistor.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a self-restoring fuse and a circuit realized by using liquid metal. Background technique [0002] A fuse refers to an electrical appliance that fuses the melt and disconnects the circuit with the heat generated by itself when the current exceeds the specified value; device. [0003] The current fuses mainly include disposable fuses and recoverable fuses; once the current disposable fuses are blown out, they need to be replaced as a whole, which is very inconvenient, and artificial replacement is very inconvenient, and there are certain safety hazards; at present The main form of the resettable fuse is a bimetallic strip thermal relay, and its on-off parts are composed of bimetallic strips with different thermal deformation coefficients. When the current is too large and the temperature of the bimetallic strip is too high, the bimetallic strip is deformed due to deformation Discon...
