A fuse is also called a fuse, which is defined by the IEC127 standard as a "fuse-link". It is an electrical component that is installed in the circuit to ensure the safe operation of the circuit. A fuse is actually a short-circuit protector widely used in power distribution systems and control systems, mainly for short-circuit protection or severe overload protection. A fuse is a current protector made by applying this principle after the current exceeds a specified value for a period of time to melt the melt by its own heat. Fuses are widely used in high and low voltage power distribution systems and control systems as well as in electrical equipment. As short-circuit and over-current protectors, they are one of the most popular protection devices. A fuse is an overcurrent protector. The fuse is mainly composed of a melt and a fusion tube and an additional filler. In use, the fuse is connected in series to the protected circuit. When the current of the protected circuit exceeds a specified value, and after a certain period of time, the heat generated by the melt itself melts the melt, causing the circuit to be disconnected, thereby protecting effect. An electrical device that breaks a circuit with a metal conductor as a melt is connected in series in a circuit. When an overload or short-circuit current passes through the melt, the melt itself is heated and melted, thereby contributing to the power system, various electrical equipment, and household appliances. Certain protection. It has anti-delay characteristics. When the overload current is small, the fuse time is long; when the overload current is large, the fuse time is short. Therefore, within a certain overload current range until the current returns to normal, the fuse will not blow and can continue to be used. The fuse is mainly composed of a melt, a casing and a support 3, wherein the melt is a key component for controlling the fuse characteristics.
