In electrified railways, pantograph–catenary (PC) arc frequently occurs in the process of train passing through split-zone insulator, which threatens current collection PC and operation electric multiple units (EMUs). So far, there have been a few studies on analysis modeling insulator. It is noting that this research different from split-phase region. This article first analyzes dynamic variation distance as EMUs pass insulator deduces formula, can reflect length according to specific...
The electromagnetic transient processes generated as a high-speed train (HST) passes the articulated split-section insulator cause over-voltages on roof and body (TB), thereby, an adverse effect is exerted electronic equipment. By this view, article focuses identifying root causes influencing factors pertinent to over-voltages. To begin with, state-space analysis method adopted examine probability characteristics of arcing. Subsequently, integrated vehicle-grid models associated with arcing...
Abstract Almost all tunnel traffic accident investigation point out that fatigue driving is one of the important causes accidents. In long process, due to acoustic characteristics tunnel, drivers are in a high noise environment for time. By recording electroencephalogram (EEG) under conditions, EEG described by using specific power spectrum, moreover, attention level measured spectrum SMR. The correlation model between different and driver’s degree obtained, influence on safety analysed....
