[0039] The fuse 100 includes a fuse tube 101, a sealing cover 102, a terminal block 103 and a fuse piece 104. The fuse tube 101 is a hollow cylinder with an open structure at both ends. The sealing cover 102 is arranged at both ends of the fuse tube 101 and is threadedly connected to the fuse tube 101. The sealing cover 102 plays a certain sealing role to prevent rainwater or dust from entering the interior of the fuse tube 101 when installed outdoors. There are two groups of terminal blocks 103, which are respectively arranged at both ends of the fuse tube 101. The terminal blocks 103 are respectively connected to both ends of the transmission line and connected in series to the line. The fuse piece 104 is arranged inside the fuse tube 101. The two ends of the fuse piece 104 are respectively bolted to the ends of the two groups of terminal blocks 103. When a fault occurs in the line connected to the terminal block 103 and causes the current to exceed the specified value, the fuse piece 104 is melted due to its own heat, so that the circuit is disconnected.

[0040] The detection mechanism 200 includes a shell 201, a signal acquisition module 202, a signal processing module 203, a control module 204, a power supply module 205 and a wireless communication module 206. The shell 201 is arranged on one side of the fuse tube 101, and the four corners of the bottom of the shell 201 are fixed to the outer wall of the fuse tube 101 by screws, which is convenient for installation and effectively saves the volume and weight of the detection device.

The two ends of the terminal block 103 are respectively connected to the transmission line and the fuse piece 104. They are used to conduct electrical energy during normal use and disconnect the circuit in time when a fault occurs.
