The Protection Application of Self Recovery Fuses in Electric Toys.fast acting fuse bussmann

　　　　With the development of technology and social progress, people are paying more and more attention to the intellectual development of infants and young children. Various educational toys are springing up one after another, including electric and non electric ones, with thousands of types and varying quality requirements.　　When people purchase toys, they often pay more attention to their playable functions and neglect their safety. Many toy quality issues are only taken seriously when accidents occur, but it is too late and have already caused harm to people, some of which may last for a lifetime.　　In foreign countries and particularly developed countries, the safety of electronic toys is the most important. Regardless of certification, testing, research and development design, customer requirements, etc., the first consideration is safety, followed by the functions of toys, especially electric toys. Therefore, the safety protection of toys is the primary issue. In clause 3.6.2 of th

　　　　1. Determine the following parameters of the circuit:　　A Large working environment temperature b Standard working current c Maximum working voltage (Umax) d Maximum fault current (Imax)　　2. Select self restoring fuse components that can adapt to the ambient temperature and standard operating current of the circuit　　Use a temperature reduction {ambient temperature (℃) working current (A)} table and select the temperature that best matches the ambient temperature of the circuit. Browse this column to view values that are equal to or greater than the standard operating current of the circuit.　　3. Compare the high electrical rating of the selected component with the high operating voltage and fault current of the circuit　　Use the electrical characteristic table to verify whether the components you selected in step 2 will use the high operating voltage and fault current of the circuit. Check the high operating voltage and high fault current of the device. Ensure that Umax and Imax are g

What is the reason why the fuse keeps burning out?

　　　　1. Exceeding rated power: Fuses have a certain rated power, and when the power of electrical equipment exceeds the rated power of the fuse, it will burn out. The function of a fuse is to protect the circuit and prevent overload.　　2. When the current resistance value of the fuse exceeds the rated current value and burns out: When there is a short circuit or poor contact in the circuit, excessive current will be generated, causing the fuse to burn out. At this point, it is necessary to check whether the circuit is normal and whether the current withstand value of the fuse exceeds the rated current value.　　3. Use environment of fuses: The service life of fuses is affected by the ambient temperature. If the ambient temperature is too high, the service life of fuses will be shortened and they are prone to burning out.　　4. Material of fuses: Fuses made of different materials have different high temperature resistance performance. If the material of the fuse is not suitable, it is also ea

30 amp screw in resettable fuse.What are the classifications of fuses and fuses that you know

　　　　There are many types of fuses, including classification by protection form, scope of use, volume, rated voltage, breaking capacity, and fusing speed. Below, we will introduce the classification by type, which can be divided into: current fuses: Shenzhen patch fuse, miniature fuses, plug-in fuses, and tubular fuses; Temperature fuse: RH square type, RP resistance type, RY metal case; Self recovery fuse: plug-in, laminated, patch.　　1、 Current fuse　　Chip fuse. There are specifications such as 0805 and 1206, which use thin film technology to accurately control electrical characteristics. Due to its small size, it is an ideal choice for providing secondary protection for circuits in space limited applications, such as handheld portable electronic devices and various instruments and meters.　　2、 Temperature fuse.　　It is an irreparable disposable thermal protection device, available in RH, RF, RY and other series. The product has a delicate appearance and structure, good sealing performanc
