AI Technical Summary
Existing fuses are inadequate in terms of current carrying capacity, electrical isolation safety, high-temperature detection accuracy, and fault response speed, and cannot meet the high-precision, fast-response, and high-reliability protection requirements of modern power systems and industrial equipment.
It adopts a fuse-free electronic switch structure, isolated magnetic field detection, negative feedback temperature drift compensation, and high-speed sampling intelligent decision design, including an isolated magnetic field detection system, a negative feedback temperature drift compensation system, a fast sampling decision system, and a power conversion system. Current detection and fast response are achieved through a Hall sensor array and an electronic control unit.
It significantly improves the current-carrying capacity, electrical isolation safety, high-temperature detection accuracy, and fault response speed of fuses, reducing the risk of equipment damage and personnel injury, and ensuring the safety of circuits and personnel.
