摘要: 局部放电 (PD) 是指未形成连接或桥接的两电极间发生局部放电的物理场景, PD 现象持续作用会极大地缩 短设备的使用寿命, 因此监测 PD 信号并识别其放电类型具有重要意义。传统的 PD 信号测量方法受限于天线本身 的金属材质以及尺寸, 在变电站开关柜等应用场景中难以实现内部近距离探测, 限制了测量灵敏度的提升。本文提 出了一种基于里德堡原子的 PD 信号测量方法, 可以实现非金属近距离内部高灵敏探测。实验中选择PD最为常见 的一种类型—电晕放电进行模块的制备与测量。首先, 通过双光子激发将铯原子激发到里德堡态; 然后, 基于里德堡 原子的交流斯塔克效应对电晕放电信号进行测量; 最后, 使用局部放电相位分辨图对测量结果进行分析, 得到电晕放 电的相位分布特征以及放电脉冲的分布情况。

Abstract: Partial discharge (PD) refers to a physical phenomenon that local discharge occurs between two electrodes without forming a full connection or a bridge. Continuous PD activity can significantly shorten the lifespan of electrical equipment. Therefore, it is crucial to monitor and identify PD signals. Traditional methods for measuring PD signals are limited by the metal materials and size of the antennas used, making it difficult to achieve near field detection inside a equipment like switchgear in substations, which limits the improvement of measurement sensitivity. This paper proposes a novel method for measuring PD signals based on Rydberg atoms, which allows for in situ near-field high-sensitive non-metallic detection. In our experiment, one of the most common types of PD phenomenon, corona discharge, is selected for model preparation and measurement. Firstly, cesium atoms are excited to the Rydberg state by two-photon excitation, and then the corona discharge signals are measured based on AC-Stark effect of Rydberg atoms. Finally, the measurement results are analyzed using the phase-resolved partial discharge spectroscopy method, and the phase distribution characteristics of the corona discharge and the distribution of discharge pulses are obtained.

Key words: quantum information, partial discharge, corona discharge, Rydberg atoms, phase-resolved partial discharge pattern
