Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a fuse with a signal transmission mechanism. Background Art

[0002] A fuse is an electrical component that is mainly used to protect the safe operation of the circuit. When a circuit fails or is abnormal, along with the continuous increase in current, some important or valuable components in the circuit may be damaged, and may even cause a fire. The fuse can cut off the current after the current abnormally rises to a certain height and a certain period of time, thereby protecting the safe operation of the circuit. Its working principle is that when the current exceeds the specified value, the heat generated by itself causes the fuse to melt and disconnect the circuit. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment, and are one of the most commonly used protective devices.

[0003] For example, Chinese patent publication number CN216120180U discloses a knife-type contact fuse, comprising a shell, a fuse body and a fixing assembly; a first contact hole is provided at the bottom of the shell; the fuse body is arranged inside the shell, and a first contact and a second contact are provided on the side wall of the fuse body; the first contact passes through the first contact hole; the fixing assembly is arranged on the side wall of the shell; the fixing assembly comprises a baffle, a cover plate and a fixing mechanism; the baffle is fixedly connected to the side wall of the shell end; the cover plate is covered at the shell end, and a second contact hole is provided on the side wall of the cover plate; the second contact passes through the second contact hole; the fixing mechanism is arranged on the cover plate; the fuse body is placed inside the shell, the cover plate is limited and clamped by the baffle, and the cover plate is locked by the fixing mechanism, so that the fuse body remains stable inside the shell, avoiding unstable installation of the fuse body affecting its use effect.

[0004] However, when the fuse in this solution blows, the fuse signal cannot be immediately transmitted to the monitoring system terminal, resulting in the inability to promptly alert the operator, and the operator cannot promptly handle the fault point, thus affecting the recovery time of the distribution system.
