AI Technical Summary
Existing transient overvoltage protection devices have a high risk of single-point failure due to the performance degradation of metal oxide varistors. They lack real-time status perception and dynamic reconstruction capabilities, and cannot identify and cut off the core protection components before their performance degrades, resulting in insufficient system resilience and unsustainable protection functions.
It adopts a system-level protection architecture that integrates state awareness, active isolation and dynamic reconfiguration. Through hardware cascaded control logic and multi-path redundancy design, it utilizes field-effect transistor switches and backup discharge paths to achieve non-disruptive switching before the performance of metal oxide varistors deteriorates, ensuring continuous protection capability.
It enables precise intervention in the early stages of performance degradation of core protection components, avoids latent failures, maintains the continuous effectiveness of protection functions by seamlessly switching to backup paths, reduces the risk of single-point failures, and meets the needs of modern industrial systems for predictive maintenance and fault resilience.
