What is the fuse made of? Fuses believe that everyone has the impression, in the old period of fuses material is not so many kinds now, there is no comprehensive popularity, a few years ago, the family circuit meter is used in the fuse, the fuse is broken after the purchase of the fuse is very troublesome, everyone is directly replaced with copper wire, although it can also matter the fuse effect, but it is very unsafe. Easy to damage electronic products. Fuses are also known as fuses, which are defined as "fuses" in international standards. It is an electrical component installed in the circuit to ensure the safe operation of the circuit. Let's take a look at what fuse it is made of.
What is the fuse made of?
Fuse material is mainly made of alloy such as aluminum-antimony alloy melting point comparison point, the main element of aluminum-magnesium alloy aluminum plate is aluminum, and then add some magnesium metal or other metal materials to strengthen its hardness.
Aluminum alloy with magnesium as the main additive element. Because of its good corrosion resistance, it is also called rust-proof aluminum alloy. Because it is metal itself, its thermal conductivity is very good. The intensity is also prominent.
The aluminum plate is strong, light, low density, good heat dissipation, and strong pressure resistance, which can fully meet the requirements of 3C products' high integration, thin and light, miniaturization, anti-crash, electromagnetic shielding and heat dissipation. Its hardness is several times that of the traditional plastic case, but the weight is only one-third of the latter.
Function and working principle of fuse
The function of the fuse is that when the circuit fails or is abnormal, the current continues to rise, and the increased current may damage the components, but also may burn the circuit or even cause a fire.
The working principle of the fuse is that when the current passes through the conductor, there is a certain resistance in the conductor, so the conductor will heat up, the material and shape of the fuse are determined, its resistance is determined, when the current flows through it, it will heat up, and its heat will increase with the increase of time, the size of the current and resistance determines the speed of heat generation. The structure of the fuse and its installation determine the speed of heat consumption, if the speed of heat generation is less than the speed of heat dissipation, the fuse will not blow.
If the speed of heat generation is equal to the speed of heat dissipation, it will not fuse for a long time, if the speed of heat generation is greater than the speed of heat disappearance, then the heat generated will be more and more, the increase in heat will cause the temperature to rise, when the temperature rises to the fuse melting point above, the fuse will fuse.
With the development of technology, there are also more types of fuses, such as recoverable fuses, which are automatically deformed when the temperature exceeds a certain safe temperature leading to power failure, and can be automatically powered on to work normally after the temperature is restored without manual intervention. What is the material of today's fuse? The content is here, I hope to help you.
