Introduction to Dropout Fuse
A dropout fuse is a type of over - current protection device commonly used in electrical power distribution systems. It consists of a fuse element enclosed in a tube. When an excessive current flows through the fuse due to a fault such as a short - circuit or overload, the fuse element melts. This causes the fuse tube to drop out of its support, visually indicating that a fault has occurred and isolating the faulty section of the power line. Dropout fuses are widely used in overhead power lines, especially in rural and suburban areas, because of their simplicity, reliability, and relatively low cost.
