Abstract

The invention discloses a reusable fuse, which comprises a casing and an active chamber, the movable chamber is installed in the casing, the movable chamber is filled with electrorheological fluid, and a slider is installed in the movable chamber. An airbag is arranged below the slider, and a linkage shaft is fixedly connected above the slider, and the slider is slidingly connected with the inner wall of the movable chamber, and the linkage shaft passes through the movable chamber, and the linkage shaft is far away from the inner wall of the slider. One end is fixedly connected with a U-shaped shaft, and the U-shaped shaft is fixedly connected with a pressing shaft. The pressing shaft passes through the casing, and connecting lines are symmetrically installed on both sides of the casing, and connecting lines are symmetrically installed inside the casing. Corresponding connection plate. The invention utilizes the inherent properties of the electrorheological fluid. When the current flowing through it is overloaded, the circuit can be effectively disconnected by simple driving, and can be reused. After the circuit is effectively disconnected, it can be used again when the circuit returns to normal. .

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a reusable fuse. Background technique [0002] A fuse refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. Melting, so as to disconnect the circuit, a current protector made by using this principle, the fuse is widely used in high and low voltage power distribution systems and control systems and electrical equipment, as a short circuit and overcurrent protector, is One of the most commonly used protection devices. [0003] During the use of the fuse, there is always a current passing through it, and it will generate heat. When it is used for a long time or the instantaneous current is too large to be limited, the inside of the fuse will automatically break and disconnect the circuit to protect the circuit. However, the circuit Once it is disconnected, replace it with a ne...
