Description

Technical Field

[0001] The utility model relates to the technical field of fuse testing, in particular to a self-recovery fuse resistance testing device. Background Art

[0002] The fuse resistance test device is a device used to test the resistance value of a fuse. A fuse is an electronic component used to protect a circuit from overload and short circuit. Its resistance value is crucial to the normal operation of the circuit. The fuse resistance test device can measure the resistance value of the fuse by applying a certain voltage and current to ensure that it meets the design requirements and can work normally. This can ensure that the circuit can cut off the current in time when a fault occurs to protect the safety of equipment and personnel. However, when the current is disconnected, self-breaking materials are used or related equipment is used to shut down the entire device. However, when the power is turned off, the next resistance wire will not be able to quickly achieve the detection effect during detection. According to the disconnection method of the existing equipment and the self-breaking material used, optimization is carried out to develop a device that can switch between disconnection and operation at will. Therefore, we propose a self-recovery fuse resistance test device. Utility Model Content
