|Type||Power wire fuse holder|
Answer 1: circuit short circuit, at this time the current intensity of the circuit instantaneous is very big, when exceeding the tolerance of the fuse, this East East will fuses.
This will protect the line from burning out.
Answer 2: When the circuit shorts, BAI's du increases dramatically through the current of the wire. When the strong current far exceeds the carrying capacity of the wire, the temperature of the whole wire DAO will rise suddenly.When this temperature reaches a certain value, the metal will melt.Using this principle, a section of metal conductor with low melting point can be connected into the circuit. The high temperature caused by large current will make this section of metal (fuse) fuse first, which ensures that the whole circuit will not be burnt out completely.
In the circuit, the fuse can be installed on the fuse block (of course, there is a fuse in the fuse), and the fuse can be of many specifications, such as 1 amp, 5 amp...It can be easily replaced.
In fact, fuse holder installation is very simple ~ generally according to product classification to distinguish the method.If the PCB board is generally welded, other similar, if you do not understand can call HINEW electronic technology consultant department, we focus on the production of fuse holder company
