Striking point is determined by color change when can be used in blown fuse, is unable to carry out early warning before blown fuse,
Its preparation process is relative complex, influences production efficiency.
The shell of existing fuse is usually plastic casing or ceramic shell, although ceramic shell high temperature resistant is more stupid
Weight, plastic casing is although light but non-refractory, and there are larger security risk, existing markets during long-time use
It is above also a kind of to use light and safe fuse.
Existing fuse in the market only has a fuse, and under service failure situation or bearing power becomes larger
When, can only be used by replacing entire fuse or replacing other specification fuses to be replaced, this under accident situation not
It is only inconvenient, for the production operations department such as factory, can equally influence production efficiency, thus fuse equally exist it is not smart enough
Defect that is convenient, influencing factory economy benefit.
