AI Technical Summary
Existing cable joint fault diagnosis methods rely on the analysis of individual joints, ignoring the signal propagation relationship between multiple joints, resulting in delayed fault diagnosis and insufficient accuracy.
A multi-source data fusion method was adopted. By selecting intermediate cable joints and adjacent terminal cable joints as diagnostic units, a high-frequency electromagnetic resonant cavity was constructed to acquire operational response signals and broadband transient signals. A reference transfer function was constructed, and time-synchronous acquisition and analysis were performed. The differences between the healthy resonance response results and the real-time response results were analyzed to determine the cause of cable joint failure.
It improves the accuracy and sensitivity of cable joint fault diagnosis, enables early warning and precise location, enhances the fault feature extraction effect, and improves the accuracy and efficiency of fault detection and diagnosis.
