Will the self-healing fuse age.lighting fuse rating

　　　　The raw materials of self restoring fuses are not prone to aging themselves. The aging condition of the self-healing fuse device is due to the close connection between the metal electrodes on both sides of the device and the raw materials of the self-healing fuse. By multiple actions, the resistance of the self restoring fuse will be higher than the original resistor. When the resistance value exceeds the main parameter R1max of the resistor after a large action, the fault indicates that the manufacturer cannot ensure that the machine equipment does not operate while maintaining the current IH.　　The raw materials of self restoring fuses are not prone to aging themselves. The aging condition of the self-healing fuse device is due to the close connection between the metal electrodes on both sides of the device and the raw materials of the self-healing fuse.

　　　　1. Select the model of the fuse according to the circuit requirements and installation conditions. For circuits with small capacity, choose semi enclosed or unfilled enclosed; The choice for high short-circuit current is the enclosed type with fillers; Select fast fuses for semiconductor component protection.　　2. Select the rated voltage of the fuse according to the line voltage.　　3. Select the rated current of the fuse according to the load characteristics.　　4. The selection of different levels of melts requires mutual coordination, with the latter level being smaller than the previous level. The current on the main switch and each branch line is different, and the selection of fuses is also different. If a short circuit occurs in the circuit, the 15A and 25A fuses will fuse simultaneously, and the protection characteristics will lose selectivity. Therefore, only by maintaining a 2-3 level difference between the main gate and the branch can such a phenomenon not occur. If the low-

　　　　Miniature fuses are primarily used in digital cameras, laptops, mobile phones, and other electronic products. From traditional glass tube fuses to miniature fuses, the selection focus varies slightly due to differences in product technology. The selection of miniature fuses involves the following elements:　　The normal operating current of the circuit should not exceed 75% of the rated current of the fuse.　　2. Pulse, pulse current, surge current, starting current, and circuit transient values. Micro fuses are particularly concerned about this. Due to technological reasons brought about by small-scale, the impact resistance of miniature fuses is much lower than that of glass tube fuses or other larger fuses with the same rated current.　　3. The size of the overload current and the minimum and maximum duration of the overload current in the circuit generally require oscilloscope testing and theoretical calculations to determine the size of the overload current. The basic requirement fo

　　　　With the development of electronic technology and the upgrading of electronic products, the requirements for reliability and safety of power electronic products are increasing day by day. How many users are troubled by issues such as electrical leakage, burning of computer hosts, and explosion of mobile phones, and how many products have been delayed from being launched due to failure to pass safety testing. The diversification and complexity of problems have led to the rapid development of circuit protection components, and today's protection devices have developed into a diverse emerging field of electronic components.　　Faced with such a complex and diverse field, we have many questions. What is the development trend of protective devices? What parameters should application engineers choose appropriate protective devices based on?　　What factors should be considered in circuit design? How to handle failure analysis when encountering a faulty machine? In response to these issues, W

very fast acting fuse.Why do fuses have high resistivity

　　　　Fuses, also known as current fuses, are defined as "fuse links" in the IEC127 standard. It mainly serves as overload protection. If the fuse is correctly placed in the circuit, the Shenzhen fuse will fuse and cut off the current when the current abnormally rises to a certain height and heat, protecting the safe operation of the circuit.　　More than a hundred years ago, the fuse invented by Edison was used to protect expensive incandescent lamps at that time. With the development of the times, the fuse protected electrical equipment from overheating and prevented serious damage caused by internal faults in electronic equipment.
