company news about What factors affect the performance parameters of fuses?

         Fuse refers to an electrical appliance that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds a specified value. A fuse is a fuse that melts the melt with the heat generated by itself after the current exceeds a specified value for a period of time, thereby disconnecting the circuit; A current protector made using this principle. Fuses are widely used in high-voltage and low-voltage power distribution systems, control systems, and electrical equipment. As short circuit and overcurrent protectors, they are one of the most widely used protective devices.An electrical appliance that uses a metal conductor as a melt in series in a circuit. When an overload or short circuit current passes through the melt, it melts due to its own heating, thereby breaking the circuit. The fuse has a simple structure and is convenient to use, and is widely used as a protective device in power systems, various electrical equipment, and household appliances.

        The specification of the selected fuse differs from the requirements of the actual application circuit;

---European and American specifications: There are significant differences in performance, even conflicting;

---Fast break and slow break: different ability to withstand pulses (I2t);

---Breaking capacity and withstand voltage: affecting safety performance;

---Fuse resistance value: affects output power and power consumption;

---Contact resistance value: affects the action time and speed of the fuse;

---Ambient temperature: affects the action time and speed of the fuse;

---Heat dissipation conditions: affecting the action time and speed of the fuse;

---Parallel connection of fuses: the rated voltage remains unchanged, and the rated current is added, resulting in a slightly longer action time;

---Series connection of fuses: the rated voltage is added, and the rated current remains unchanged, without practical significance
