High Voltage, EarlyView.ABSTRACT As a commonly used bushing current‐carrying structure in recent years, contactor‐type electrical connection parts operate in a complex environment of electric, thermal and chemical corrosion for extended periods. With the increase of ultra‐high voltage (UHV) transmission capacity, its operating environment faces more stringent challenges, and ...

气体分解产物和局部放电测试技术在SF6电气设备状态诊断中的应用
Gaoya dianqi, 2014 主要介绍了SF6气体分解产物、局部放电测试这2种检测技术在SF6电气设备状态诊断中的几起成功应用的案例。这些案例各有特点:SF6气体分解产物异常但不存在局部放电信号;SF6气体分解产物正常但存在局部放电信号;SF6气体分解产物异常且存在局部放电信号;SF6气体分解产物异常但无法采用局部放电测试技术进行检测。通过解体,均验证了设备存在缺陷。因此,SF6气体分解产物、局部放电测试技术在SF6电气设备潜伏性故障诊断方面具有广阔的应用前景。

Electron attachment to SF6 and lifetimes of SF6- negative ions
, 2008 We study the process of low-energy electron capture by the SF6 molecule. Our approach is based on the model of Gauyacq and Herzenberg [J. Phys. B 17, 1155 (1984)] in which the electron motion is coupled to the fully symmetric vibrational mode through a weakly bound or virtual s state.

High Voltage, EarlyView.ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

The finite-temperature Monte Carlo method and its application to superfluid helium clusters
, 2002 We review the use of the path integral Monte Carlo (PIMC) methodology to the study of finite-size quantum clusters, with particular emphasis on recent applications to pure and impurity-doped He clusters. We describe the principles of PIMC, the use of the
