基于里德堡原子的真型GIS局部放电量子传感检测
Quantum Sensing Detection of Local Discharge Using a True-type GIS Based on Rydberg Atoms
摘要
Abstract
Gas-insulated switchgear(GIS)is a critical piece of equipment,and the assessment of its insulation condition relies heavily on the early detection of partial discharge(PD).Existing detection methods,such as the ultra-high frequen-cy(UHF)technique,still face limitations in practical applications,including insufficient sensitivity,weak anti-interference capability,and difficulties in feature extraction.To overcome the bottlenecks of conventional detection technologies and address the frequency band limitation of traditional UHF detection(0.3～1.5 GHz),this study employs a cesium atomic vapor cell with a center frequency of 3.27 GHz for the first time.Targeting the frequency range beyond the reach of UHF methods,a full-scale GIS partial discharge quantum detection platform was constructed,and the Rydberg atom quantum sensing technology is applied to investigate protrusion and floating defects in a 126 kV full-scale GIS.Ex-perimental results demonstrate that the quantum detection system achieves a signal detection limit of 10 mV,with the measured PD amplitude being 0.6 times that of the UHF signal,exhibiting a linear correlation between the two.Statistical analysis of discharge amplitude versus discharge repetition rate reveals that the repetition rate of protrusion defects is sig-nificantly higher than that of floating defects.Furthermore,maps of discharge amplitude-pulse count and discharge amplitude-pulse interval time were statistically compiled,revealing the intrinsic differences between the two defect types.These findings validate the feasibility of the Rydberg atom technology for GIS partial discharge detection and lay a foun-dation for insulation defect identification using quantum sensing.关键词
