Abstract

This invention discloses a method and system for identifying safety hazards in power equipment, specifically relating to the field of intelligent operation and maintenance technology for power equipment. It addresses the hidden operational risks caused by the mismatch between equipment aging characteristics and generalized strategies in existing technologies. By collecting multi-source operating status data of power equipment and constructing an asynchronous dataset, it dynamically identifies spatial electric field distortion gradients and contact resistance fluctuations as abnormal parameters. Based on equipment structural characteristics, it assigns differentiated weights to these abnormal parameters, quantifying the risk levels of different areas. It analyzes the temporal correlation between contact resistance and electric field response to determine the breakdown risk caused by insulation degradation. Combining the risk levels, it generates maintenance cycle optimization schemes and electric field compensation parameters, and dynamically updates the aging model based on execution feedback. Through dynamic adaptation of equipment status and control strategies, it achieves early warning and precise intervention for potential hazards, effectively solving the control mismatch problem caused by neglecting material degradation characteristics in traditional methods.
