Problems solved by technology

[0003] During the use of existing fuses, when lightning strikes or electrical appliances with excessive power are connected, the overload is too large, and the input current suddenly increases, which causes the fuse to be disconnected instantaneously when heated, resulting in an open circuit. However, Due to the sudden instability of the current, the fuse disconnects the line, which makes the user need to open the fuse and replace the fuse every time. For ordinary residents, frequent replacement of the fuse is cumbersome.

Abstract

The invention discloses an automatically recoverable fuse, which comprises a casing, the casing is a hollow structure, and the upper end and one side wall of the casing are respectively provided with a first connection port and a second connection port, the A bearing is embedded on the bottom side wall of the housing, and the bearing key is connected with a vertically arranged rotating shaft. A sleeve is sleeved on the outer side wall of the rotating shaft, and one end of the sleeve is connected to the bottom side of the housing The wall is fixedly connected, and a limiting device for limiting the rotation of the rotating shaft is provided between the sleeve and the rotating shaft. A rotating block is fixedly connected to the upper end of the rotating shaft, and the rotating block is a hollow structure. There are many surrounding arrays in the rotating block. One installation tube, one end of the installation tube is connected with the side wall of the rotating shaft, and the other end of the installation tube is connected with a metal contact. In the present invention, the fuse can automatically restore the conduction to the circuit after being overloaded and disconnected, so as to avoid frequent replacement of the fuse or fuse, thereby avoiding the danger of replacement.

Description

technical field [0001] The invention relates to the technical field of circuit protection equipment, in particular to an automatically recoverable fuse. Background technique [0002] A fuse is an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. [0003] During the use of existing fuses, when lightning strikes or electrical appliances with excessive power are connected, the overload is too large, and the input current suddenly increases, which causes the fuse to be disconnected instantaneously when heated, resulting in an open circuit. However, Due to the sudden instability of the current, the fuse disconnects the line, and the user needs to open the fuse every time to replace the fuse. For ordinary residents, frequent replacement of the fuse is cumbersome. [0004] For this reason, we propose an automatically recoverable fuse to solve the above problems. Contents of the inv...
