A fuse is also called a melt or a fuse link. It is an electrical component installed in a household circuit. The fuse is made of a metal wire made of silver and copper with a relatively large resistance but a low melting point. The fuse is used when repairing household appliances and appliances. It is also essential, so what is the structure of the fuse? Then the following editor will introduce the structure and function of the fuse for everyone. The main components of professional fuse production are as follows:
One is the electrode part, which is the bridge between the melt and the circuit, and it must have strong electrical conductivity. In fusing, the circuit is cut off by an arc, and the strength of the arc is related to the electrode part of the circuit. The electrode is the conductive device in it which greatly affects the voltage. The rated voltage of the fuse can withstand the circuit voltage when the fuse is blown. Therefore, when the voltage is higher than its rated voltage, the arc is not easy to extinguish and may cause dangers such as burning.
The second is the melt part, which is the core part of the fuse. It cuts off the circuit when it is blown. The resistance value is as small as possible and the value is consistent. The most important thing is to have the same fusing characteristics. When the fuse is energized, the electric energy is converted into heat due to its own resistance to heat the melt. When the amount of electric current passing through the fuse reaches a certain value, the heat energy converted from the electric energy soars, and the heat dissipation speed cannot keep up with the fever speed. Sublimation will gradually accumulate on the melt. When the heat reaches the melting point of the melt, the fuse starts to melt and continues to attract heat to further melt and form an arc.
The third is the bracket part. The function of the bracket in the fuse is to fix the melt and facilitate installation, so that the professional fuse is more stable, and the usable environment range is wider.
The fuse is an electronic device that protects the circuit from overload. When the current in the fault circuit soars to a certain value, the fuse will blow itself and cut off the circuit to decompose the load, so as to protect the other components in the circuit and ensure the safe use of electricity. It is mainly composed of melt, bracket and electrode, and each plays a crucial role. They complement each other to form a complete circuit safety protection barrier. This is the structure and function of the fuse introduced by the editor.
