Self-mending fuse of liquid metal structure

Abstract

The invention discloses a self-mending fuse of a liquid metal structure, and relates to the technical field of fuses. The fuse comprises a porcelain tube, and two ends of the porcelain tube are respectively provided with a first electrode fixing seat and a second electrode fixing seat, wherein the first electrode fixing seat is provided with a first electrode and a second electrode, and the secondelectrode fixing seat is provided with a third electrode and a fourth electrode. The interior of the cavity of the porcelain tube is provided with liquid metal conductor which is electrically connected with the first electrode and the third electrode. When the accidental conditions of fire, short circuit and emergent high temperature happen, the liquid metal conductor can melt to fall to the bottom, and the two idle electrodes at the bottom are connected, and then the circuit is completely cut off, thereby achieving the protection of the circuit; after the accidental conditions are avoided, the fuse is taken out and rotated for 180 degrees, and then is installed again for reuse, thereby solving a problem of inconvenient replacement, improving the maintenance efficiency, and saving the replacement cost.

Description

technical field [0001] The invention relates to the technical field of fuses. Background technique [0002] A fuse is a kind of electrical appliance that uses a metal conductor as a melt in series in the circuit. When an overload or short-circuit current passes through the melt, it will fuse due to its own heating, thereby breaking the circuit. A current protector made by using this principle. Fuses are widely used in power systems, various electrical equipment and household appliances, as short-circuit and over-current protectors, and are one of the most commonly used protection devices. [0003] Common types of fuses include [0004] Plug-in fuse: It is often used at the end of the line with a voltage level of 380V and below, as a short-circuit protection for distribution branch lines or electrical equipment. [0005] Spiral fuse: There is a fuse indicator on the upper end cover of the fuse. Once the fuse is blown, the indicator pops up immediately and can be observed t...
