Function Of Time Delay Micro Fuses
1. Under normal circumstances, disposable fuse plays the role of
connecting the circuit in the circuit.
2. Under abnormal (overload) circumstances, one-time fuse as a
safety protection element in the circuit, through its own fuse
safety cut off and protect the circuit.
Working Principle Of Time Lag Micro Fuses
When a one-time fuse is energized, the heat converted by electrical
energy raises the melt temperature. When the normal working current
or allowed overload current passes through, the heat generated will
radiate to the surrounding environment through the melt and outer
shell, and the heat emitted by convection and conduction will
gradually reach the balance with the heat generated.If the heat
generated is greater than the heat emitted, the excess heat will
gradually accumulate in the melt, causing the melt temperature to
rise.When the temperature reaches and exceeds the melting point of
the melt, it will make the melt melt, fuse and cut off the current,
played the role of safety protection circuit.
