AI Technical Summary
In the existing technology, the arc imaging method for insulator impulse breakdown tests cannot effectively integrate multi-modal sensing information, resulting in inaccurate prediction of the discharge initiation time, unstable image quality, and affecting the accuracy and reliability of breakdown mechanism analysis.
A multi-modal signal acquisition module is used to acquire signals from a PD detector, Rogowski coil, and electric field sensor. The time-varying weighted fusion module performs adaptive weighted fusion and time alignment. Combined with a two-stage time-series prediction module and a constrained multi-objective optimization module, a synchronous trigger signal is generated to control a multi-frame camera to perform arc imaging.
It achieves high-precision automatic shooting and high-quality imaging of the arc during insulator impulse breakdown tests. Through adaptive weight calculation, ball gap discharge mode recognition and dynamic timing alignment, it accurately predicts the discharge initiation time, optimizes camera parameters, and improves the accuracy and reliability of breakdown mechanism analysis.
