Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a rectifier fast fuse. Background Art

[0002] A fuse is an electrical device that uses the heat generated by itself to melt the fuse and disconnect the circuit when the current exceeds the specified value. A fuse is a current protector made based on the principle that after the current exceeds the specified value for a period of time, the heat generated by itself will melt the fuse and disconnect the circuit. Fuses are widely used in rectifiers as short circuit and overcurrent protectors and are one of the most commonly used protection devices. At present, after the existing fuses are installed, the two ends of the fuse are usually exposed, and the exposed fuse is easily accidentally touched by the outside, causing the fuse to short-circuit. To this end, we propose a rectifier fast fuse. Utility Model Content
