Research on Partial Discharge Detection Technology for Environmental Protection Gas Ring Main Cabinet Equipment in Distribution Network
Aiming at the problem of weak partial discharge signals in environmental-friendly gas ring main unit equipment of distribution networks,which are easily influenced by multiple factors and lead to low detection sensitivity,this study proposes a partial discharge detection technology for such equipment.By utilizing Rogowski coil sensors,combined with signal amplification,A/D conversion,and digital signal processing technology,local discharge signals are effectively extracted and denoised through three-level wavelet packet decomposition and variational mode decomposition techniques.Weighted fuzzy C-means clustering algorithm and support vector machine are employed to identify different discharge patterns.Experiments demonstrate that this technology can significantly enhance the sensitivity of partial discharge detection.
