Example Embodiment
[0022] Example 1
[0023] Such as figure 1 As shown, the prototype fuse includes an insulator body 8, a fuse barrel 72, an insulating barrel 73, a lower electrode fixing ring 79, an upper electrode 74 and a sealing assembly 9. The prototype fuse of the present invention extends the overall length of the insulator body 8, the fuse barrel 72, the insulation barrel 73 and the fuse to improve the pressure resistance of the fuse and increase the creeping distance, so that it can be used in a plateau environment .
[0024] Such as figure 2 , 3 4, the fuse cartridge 72 is arranged inside the insulator body 8. The fuse cartridge 72 includes the fuse cartridge cover 1, the fuse assembly 2, the arc suppression cartridge 3, the lower contact metal 4, the connecting sleeve 7, and the spring 5 and the bottom sleeve 6, the fuse assembly 2 includes a fuse 21 and a metal lead 22, the fuse 21 can be blown when the line is overloaded or short-circuited, and the line is disconnected, thereby achiev...
