AI Technical Summary

Technical Problem

After the protection action is completed, existing smart fuses often have intact ignition devices remaining inside, which poses a safety hazard and has insufficient breaking capacity.

Method used

The synchronous trigger fuse control circuit is adopted, and two sets of ignition devices are triggered separately or jointly by internal and external trigger modules to ensure that they can be triggered under abnormal operating conditions, forming a multi-break fast disconnect circuit.

Benefits of technology

The problem of ignition device residue has been solved, and the breaking capacity and insulation resistance have been improved, the arc can be extinguished quickly, and the safety hazards have been reduced.

Abstract

The application provides a synchronous trigger fuse control circuit and a synchronous trigger fuse, which comprise an internal trigger module and an external trigger module; the external trigger module is connected to a conductor of the synchronous trigger fuse and is used for receiving an external trigger signal; when the external trigger signal is received or an internal trigger signal on the conductor is collected, a first ignition device is triggered to cut off the conductor to cut off a protected circuit; the internal trigger module is connected to the conductor of the synchronous trigger fuse and is used for triggering a second ignition device to cut off the conductor to cut off the protected circuit when the internal trigger signal on the conductor is collected; or the second ignition device is triggered to cut off the conductor to cut off the protected circuit according to a second current generated after the conductor is cut off. Through the synchronous trigger mechanism, the first ignition device and the second ignition device can be triggered, and the problem that there is still an ignition device with gunpowder left after the fuse ends the protection action is solved.
