Technical Field
[0001] The utility model relates to the technical field of fuses, in particular to a novel improved fuse sand filling device. Background Art
[0002] For high breaking capacity fuses, the sand filling amount and density are the key to efficient arc extinguishing ability. Traditional sand filling methods such as Figure 1 As shown, a hole 00 is directly punched on the cover plate of the fuse, and sand is loaded from the hole. After the sand is loaded, the hole needs to be blocked. The existing sand loading method has the following defects: (1) The sand loading hole is too small, the sand loading speed is slow, and the production efficiency is low; (2) The sand loading hole is too small, and the quartz sand is piled at the same position during operation, causing uneven sand loading and voids in the internal structure of the product; (3) The sand loading position inside the product cannot be clearly observed during operation, the sand loading amount is not accurate enough, and the sand loading density effect is poor. In addition, additional drilling and blocking are required.
