To address the causes of fires in energy storage stations, this study proposes an fire warning and protection technical solution. First, an acoustic warning system based on ultrasonic technology is developed to achieve ultra-early fire detection. A novel alloy-oxide composite material for DC feeder thermal fuse wires is investigated, demonstrating exceptional thermal arc-extinguishing and flame-retardant properties. The design leverages rapid interruption technology for DC transmission line faults, integrating the material's flame-ratardant feature to enable multi-level arc suppression and fire prevention.
