Description

Fuse structure with arc-extinguishing silicone composition

Technical Field

Background

The fuse is an electric appliance which fuses a melt by heat generated by itself to open a circuit when a current exceeds a predetermined value. The fuse melts the melt by the heat generated by the fuse after the current exceeds a specified value for a period of time, so that the circuit is disconnected; a circuit protector is made by applying the principle. Fuses are widely used in high and low voltage distribution systems and control systems as well as in electrical equipment, and are one of the most commonly used protectors as short circuit and overcurrent protectors. When the fusible elements of the fuse separate due to an overcurrent condition, an arc may sometimes propagate between the separate portions of the fusible elements (e.g., through the remaining vaporized particles between the separate portions of the fusible elements). If not extinguished, the arc may allow a significant amount of subsequent current to flow from the power supply to the protected components in the circuit, which may result in damage to the protected components despite the physical opening of the fusible element. In addition, the heat generated by the arc may burn and/or break the fuse body of the fuse, which may cause damage to surrounding components. It is therefore desirable to extinguish the arc as quickly as possible to prevent or mitigate any damage to the connected components and surrounding components that may result therefrom.
