What is the principle and material of a fuse.mini blade fuse box

　　　　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

plastic fuse box under stairs.Discussion on the Application of Fuses on LED Beads

　　　　1、 Firstly, analyze the causes of LED bead damage, which are usually caused by the following reasons　　① A sudden increase in power supply voltage.　　② The temperature inside the lamp is too high　　③ Short circuit in the circuit.　　④ Failure to do a good job in preventing static electricity during assembly has caused damage to the interior of the LED lamp beads due to static electricity. Although normal voltage and current values are applied, it is extremely easy to cause damage to LED beads　　⑤ The voltage and current of the circuit are unstable.　　2、 How to protect the circuit of LED beads?　　Answer: Nowadays, many circuits use fuses for overload protection, but disposable fuses are not suitable for LED lamp products because the circuits of LED beads are very different from those of other products. LED bead circuit overload is caused by the overload protection component, which immediately disconnects the LED bead circuit and automatically restores power supply after the circuit is norma

The Application of Self Recovery Fuses in Air Fresheners.supercheap auto blade fuse

　　　　Air purifiers, also known as air filters, can filter out impurities in the air and output clean air. In this era of industrial pollution and severe smog, air purifiers have become essential equipment widely used in homes, hotels, and other places. It consists of three parts: control circuit, mechanical and detection status indication. The mechanical part involves the fan motor passing indoor air through a filter and circulating impurities to achieve air purification.　　The core of an air purifier is a small motor. In this transmission system mechanism, small motors are prone to overload or rotation due to problems such as mechanical lack of lubricating oil, bearing wear, rust, dust, etc., ranging from burning out the motor to burning out the motor and wires, and even leading to fire accidents. So it is necessary to design overload protection and gambling protection circuits for the motor to ensure safe operation.　　Traditional designs often use bimetallic temperature controllers as o

The impact of the development trend of the electronic industry on the fuse industry.mini fuse vs micro fuse

　　　　Electronic components are entering a new generation of components era dominated by new electronic components, which will basically replace traditional components. Electronic components have changed from being mainly improved to meet the miniaturization and new process requirements of the entire machine, to a stage of industrial development that mainly meets the characteristic requirements proposed by the development of digital technology and microelectronics technology, and is a complete set of requirements.　　In recent years, the demand for information technology, mobile and consumer electronic devices in the market has sharply increased, and with the increasing functionality of products, the risk of unexpected situations in such electronic devices has correspondingly increased. Manufacturers' safety awareness in overall circuit protection design has also been continuously improved, and the production capacity of the fuse market has continued to expand.　　The mainstream trend of ele

　　　　1. According to the protection form: overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current limiting fuse). Fuses used for overheating protection are generally referred to as "temperature fuses". Temperature fuses are also divided into low melting point alloy type, temperature sensing contact type, and memory alloy type, etc. Temperature fuses are used to protect against excessive temperature changes in heating appliances or Yi Ge heating appliances, and their working principle is different from "current limiting fuses" The melting of temperature fuse melts is independent of the operating current of the circuit.　　2. According to the scope of use: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), automotive fuse.　　3. According to the rated voltage level: high-voltage fuse, low positive fuse, and safety voltage fuse.　　4. According to breaking capacity: high break
