company news about The charging pile fuse is a current protector

        The charging pile fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made using this principle. Fuses are widely used in low-voltage power distribution systems, control systems and electrical equipment. As a short-circuit and over-current charging pile protector, it is one of the most commonly used protection devices.

        The charging pile fuse is an overcurrent protector. The charging pile fuse is mainly composed of melt, melting tube and external filler. When in use, connect the charging pile fuse in series with 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 and disconnects the circuit. Protect the role of charging piles.

        An electrical appliance that uses a metal conductor as a melt to break the circuit is connected in series in the circuit. When an overload or short-circuit current passes through the melt, the melt itself will heat up and fuse, which will play a role in the power system, various electrical equipment and household appliances. certain protection. It has the characteristic of inverse time delay. When the overload current is small, the fusing time is long; when the overload current is large, the fusing time is short. Therefore, within a certain overload current range until the current returns to normal, the fuse will not be blown and can continue to be used. The fuse is mainly composed of three parts: the melt, the shell and the support. The melt is the key element to control the fusing characteristics.
