7100.1020.13 Application Field and Working Principle

Fuses have been around for hundreds of years. The earliest examples were pieces of hay wire wrapped in a coil of cotton which were used to protect electrical circuits. Over the years, fuses have evolved into the modern versions which are commonly used in many electrical and electronic applications today.

Application Field

The primary use of fuses is to protect electrical circuits from overloads or short circuits. Fuses are used in vehicles, buildings, and other industrial or commercial settings, as well as in consumer electronics and appliances. In addition, fuses are also used in industrial control systems.

Fuses are also used to prevent damage in case of a power surge. A surge is an abnormal increase in voltage or current that can occur suddenly. If a surge is large enough, it can cause significant damage to equipment and the electrical system. A fuse can be used to limit the surge current, thus protecting the equipment.

Working Principle

The basic working principle behind fuses is to interrupt an electrical circuit when a certain level of current is exceeded. This is accomplished by placing a strip of metal known as the fuse element inside of a device. This metal strip is designed to heat up when the circuit current reaches a certain level.

When the current reaches this level, the heat generated melts the fuse element. This effectively cuts off the circuit, preventing further current from flowing. This prevents damage to the equipment or wiring. It should be noted that the fuse will need to be replaced once it has been tripped, or it will not protect the circuit again.

Conclusion

In conclusion, fuses are an important and reliable form of electrical protection. They are used in many different applications and settings to protect equipment from electrical overloads or power surges. The basic working principle of fuses is to limit the amount of current flowing through a circuit by cutting it off when the current exceeds a certain level.
