company news about Introduction of charging pile fuse

        The charging pile fuse is a current protector based on the principle that after the current exceeds the specified value for a period of time, it will melt the melt with the heat generated by itself, so as to disconnect the circuit. Fuses are widely used in low-voltage distribution systems, control systems and electrical equipment. As short circuit and over-current charging pile protectors, fuses are one of the most widely used protective devices.

        The charging pile fuse is an overcurrent protector. The fuse of the charging pile is mainly composed of the melt, the fuse tube and the external filler. When in use, the fuse of the charging pile is connected in series to the protected circuit. When the current of the protected circuit exceeds the specified value and after a certain period of time, the heat generated by the melt itself fuses the melt to disconnect the circuit, thus protecting the charging pile.

        The electrical appliances that break the circuit with metal conductor as the melt are connected in series in the circuit. When the overload or short circuit current passes through the melt, the melt itself will heat and fuse, thus playing a certain role in protecting the power system, various electrical equipment and household appliances. With anti time delay characteristics, when the overload current is small, the fusing time is long; When the overload current is large, the fusing time is short. Therefore, the fuse will not fuse and can continue to be used until the current returns to normal within a certain overload current range.

        The fuse has simple structure and is easy to use. It is widely used in power systems, various electrical equipment and household appliances as a protective device.
