Power systems are the backbone of modern society, supplying electricity to homes, businesses, and industries. Power system fuses play a fundamental role in maintaining the integrity and safety of these systems. Power system fuses are designed to protect the power grid at various levels. At the transmission level, where high - voltage electricity is carried over long distances, these fuses need to be able to handle extremely large currents. They are often installed in substations and are part of the protection scheme for transformers, transmission lines, and other key components. For example, a large - scale power transmission line may carry currents in the tens of thousands of amperes. The fuses in such a system must be able to detect and interrupt overcurrents quickly to prevent damage to the transmission infrastructure. In the distribution system, which delivers electricity to end - users, power system fuses also have a crucial role. They protect against faults in the distribut
Low voltage fuses play a crucial protective role in power systems and electronic devices. Low voltage usually refers to circuit environments with AC voltage of 1000V or below or DC voltage of 1500V or below. In such low-voltage systems, fuses serve as a safety device that can quickly cut off current in the event of abnormal conditions such as overload or short circuit, protecting equipment and circuits from damage. The working principle of low-voltage fuses is based on their special materials and structural design. It usually consists of parts such as melt, shell, and support. Melt is the core component of fuses, usually made of low melting point metal materials such as lead, tin, zinc, etc. When the current in the circuit exceeds the rated current of the fuse, the melt heats up and gradually melts, eventually disconnecting the circuit. Low voltage fuses have multiple advantages. Firstly, it has a fast response speed and can instantly cut off excessive current to prevent the fau
Self recovery fuse is a new type of overcurrent protection component with unique performance and wide application prospects. The working principle of self-healing fuses is based on the positive temperature coefficient (PTC) characteristics of polymer materials. Under normal working conditions, its resistance value is very low, and its impact on the circuit can be ignored. When an overcurrent fault occurs in the circuit, the temperature of the self recovering fuse will rapidly increase, causing its resistance value to sharply increase, thereby limiting further increase in current and protecting other components in the circuit from damage. Once the fault is resolved and the temperature drops, the self recovering fuse will automatically return to a low resistance state, and the circuit will resume normal operation. Self recovering fuses have many advantages. Firstly, it has a self recovery function that eliminates the need to replace fuses, greatly reducing maintenance costs and dow
Principle and characteristics of self recovering fuses With the rapid development of technology, our daily lives are increasingly dependent on various electronic devices. However, the normal operation of these devices relies on a stable and reliable power protection system. As an innovative power protection solution, self recovering fuses are gradually becoming an indispensable part of modern electronic devices. Self recovery fuse is a type of fuse with overload protection function, whose main principle is to quickly cut off the current when it exceeds the rated value to prevent equipment from overheating or damage. After the current returns to normal, the self recovering fuse will automatically return to its normal working state without manual intervention. Compared with traditional fuses, self-healing fuses have the following characteristics: a. Self recovery function: Once the current returns to normal, the self recovery fuse will automatically return to its normal working stat
Surface mount fuse is a widely used protective component in electronic circuits. Structurally speaking, patch fuses are compact in size and typically flat in shape. They are designed to be suitable for surface mount technology (SMT) and can be easily installed on printed circuit boards (PCBs). This compact structure gives it a unique advantage in the trend of miniaturization in modern electronic devices, effectively saving space on circuit boards. Its working principle is based on the thermal effect of electric current. When the current in the circuit exceeds the rated current of the patch fuse, the resistance wire inside the fuse will heat up, and as the heat accumulates, the temperature of the resistance wire will rapidly rise. When the temperature reaches the melting temperature of the fuse, the resistance wire will melt, thereby cutting off the circuit and protecting other components in the circuit. In terms of application fields, patch fuses are very common in various consu

Its working principle is to quickly cut off the current when the circuit temperature rises to the set value through the characteristics of ceramic materials, thus protecting the circuit and equipment. 2、 The advantages of ceramic temperature fuses Stable and reliable: Ceramic temperature fuses are made of high-quality ceramic materials, which have high stability and reliability, and can maintain stable protection performance during long-term use. High temperature triggering: Ceramic temperature fuses use ceramic materials that are very sensitive to high temperatures. When the circuit temperature exceeds the set value, the fuse will immediately cut off the current to avoid damage to the circuit and equipment caused by excessive temperature. Safety protection: Ceramic temperature fuses can quickly respond and cut off current,
