Electronic Structure Properties of Two-Dimensional π-Conjugated Polymers
TL;DR: In this paper, a comprehensive electronic structure investigation of several representative 2D conjugated polymers by virtue of first-principles density functional theory (DFT) calculations is presented.
Journal ArticleDOI
Influence Mechanisms of Trace H2O on the Generating Process of SF6 Spark Discharge Decomposition Components
TL;DR: In this paper, a series of spark decomposition experiments of different proportions of SF6/H2O mixtures were conducted with a trace H2O injector accurately controlling H 2O content.
Journal ArticleDOI
First principles based computational scheme for designing new SF 6 replacements
TL;DR: In this article, an efficient and economic computation-based scheme which can semi-quantitatively predict the thermodynamics and electric properties of new SF6 substitute insulation gases with a statistical model combined with quantum chemical calculations is presented.
Journal ArticleDOI
Study on the influence rules of trace H2O on SF6 spark discharge decomposition characteristic components
TL;DR: In this article, a series of spark discharge decomposition experiments with various H2O contents were performed using needle-plate electrode to simulate metal protrusion insulation defect, and the changing rules and mechanisms of five decomposition characteristic components were achieved quantitatively.
Proceedings ArticleDOI
Induction motors lifetime expectancy analysis subject to regular voltage fluctuations
TL;DR: In this paper, the lifetime impact of voltage fluctuations on induction motor, particularly the induction motor operating lifetime reduction which is contributed from stator current variation characteristic, is investigated, and the results show that the decrease of induction motor lifetime caused by voltage fluctuations is considerably depended on voltage change, modulation frequency and load level, and this reduction tendency cannot be indicated by the flicker index P st value.
