* Question
| The working principle and use of the fuse |
* Answer
| The fuse is the simplest and most effective protection device, mainly used for short circuit protection and severe overload.Normally, the melt is allowed to pass a certain current; when the circuit is short-circuited or severely overloaded, a large fault current flows through the melt. When the heat generated by the current reaches the melting point of the melt, the melt is blown and the circuit is cut off.For protection purposes.Second, type 1. Porcelain plug 2. Spiral 3. Closed tube 4. Self-replicating |
