AI Technical Summary

Technical Problem

Existing power electronic transformers lack a visual sensor, electric actuator, and a coordinated arc warning locking structure for the transformer body, making it impossible to capture arc flash signals inside the equipment, leading to potential safety hazards. Furthermore, the sealed door is easily opened by mistake, violating safety regulations.

Method used

A power electronic transformer comprising a vision sensor, an electric push rod, and a capsule was designed. The vision sensor captures arc flash signals to automatically trigger the sealing door to lock. Combined with a magnetic attraction structure and multiple limit switches, the sealing door is ensured to be stable. An automatic cleaning system is also provided to prevent accidental opening.

Benefits of technology

It enables rapid detection of abnormal equipment signals, automatic locking of sealing doors to prevent safety accidents, improves equipment sealing and cleaning efficiency, and reduces the labor intensity of operators.
