　　When current passes through a conductor, contact occurs and the conductor may generate heat because it has a certain resistance. And the calorific value is calculated according to this formula: Q=0.24I2RT.

　　2. Among them, Q is a calorific value and 0.24 is a parameter. I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time flowing through the conductor. By using this formula, you can easily discover the simple principle of fuses.

　　When the raw materials and appearance of the fuse manufacturing are clear, its resistance R is relatively clear (if its resistance temperature coefficient is not considered). When an electric current flows through it, it becomes hot, and over time, its calorific value also increases.

　　4. The height of current and resistance determines the speed of thermal energy, while the structure and assembly of the fuse determine the speed of thermal energy loss. If the speed of thermal energy is lower than the speed of thermal energy loss, the fuse is less likely to melt.

The key elements of damage to vehicle fuses include the following aspects.fast blow fuse time

　　　　1. Unauthorized modification of vehicle lights　　Many car enthusiasts are fond of modifying high-power headlights or xenon lamps. However, if the vehicle's headlights exceed the original overall planned output power or have a large load, it is inevitable that the fuse will melt. Suggest that if there is insufficient technical expertise or no need to tamper with the modification of cars.　　2. Modify a high-power speaker　　Some buyers want to have the actual effect of Auditory system, which may be modified. But when the output power and disorder of the speaker exceed the original overall plan, the fuse will also melt.　　3. Rinse the engine hood with tap water　　Many people wash their cars in the wrong way. For example, in the summer, many people require a water gun to wash the engine hood when washing their cars, and using a high-pressure water gun with such a high pressure to clean the engine hood can also easily cause short circuit faults in the power circuit.

The Application of Self Recovery Fuses in Automotive USB Systems.battery terminal fuse nissan problems

　　　　Nowadays, cars generally come with USB 3.0 ports. In addition to overcurrent and overvoltage protection, sensitive electronic devices using high-speed interfaces such as USB and HDMI also require electrostatic discharge (ESD) protection. Three different types of circuit protection devices can help avoid these potential destructive events.　　PolySwitch polymer positive temperature coefficient (PPTC) devices can provide self-healing protection in USB applications. Placing the PolySwitch PPTC device on the VBUS port of the USB power supply can limit the current during short circuit events, help prevent damage caused by sudden short circuits, and help achieve UL60950 compliance.　　The design of USB 3.0 uses circuit protection devices to help prevent overcurrent (PTTC, left) and overvoltage (PolyZen, right) damage at the power port, as well as ESD (SESD device) events at the data port　　For overvoltage protection in USB 3.0 applications, PolyZen devices use a hybrid approach that integrate

Introduction to the Classification of High Voltage Fuses.lighting fuse size

　　　　The heat emitted by high-voltage fuses through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the excess heat gradually accumulates on the melt, causing the temperature of the melt to rise; When the temperature reaches or exceeds the melting point of the melt, it will cause the melt to melt, fuse, and cut off the current, playing a role in safety protection of the circuit.　　Classification of high-voltage fuses:　　1. Divided into: φ 2 φ 3 φ 4 φ 5 φ 6 and others.　　2. According to the fuse characteristics, it is divided into fast fuse type, medium delay fuse type, and delay fuse type. (It can also be divided into express and strong delay).　　3. According to the breaking capacity, it can be divided into low breaking type, high breaking type (and can also be divided into enhanced breaking type).　　4. According to safety standards (or usage regions), it can be divided into UL/cUL (North
