Influence of the Crosswind on the Pantograph Arcing Dynamics

IEEE Transactions on Plasma Science, 2020
As one of the most important electrified railway components, the pantograph-catenary (PC) system plays a key role in the energy transfer for the train through the sliding electric contact. However, the performance of the PC system is severely limited by pantograph arcing, and the study on the dynamic characteristics of pantograph arcing is still far ...

Experimental study of electrical characteristics on pantograph arcing

2011 1st International Conference on Electric Power Equipment - Switching Technology, 2011
Perfect sliding electrical contact between pantograph and catenary can guarantee the safety and stability of locomotive. Pantograph arcing is one of the main factors of sliding electrical contact performance in electrified railway system. The main reason of pantograph arcing is the varying gap due to the mechanical vibration between pantograph and ...

Pantograph–Catenary Arcing Detection Based on Electromagnetic Radiation

IEEE Transactions on Electromagnetic Compatibility, 2019
Currently, the detection equipment for offline arcing on high-speed trains is of great interest because it can evacuate the contact state between the contact wire and the strip. In order to ensure the safety of the train under the effect of the arcing, the self-designed fourth-order Hilbert curve fractal antenna is chosen to detect the arcing, in this ...

Electromagnetic noise of pantograph arc under low current conditions

International Journal of Applied Electromagnetics and Mechanics, 2017
With the continuous increase of electric locomotive running speed, electromagnetic noise of pantograph arc gets more and more serious and has become a kind of safety risk of electric railway's operation. With the self-developed electromagnetic noise experimental system, 66 groups of radiation electromagnetic noise experiments were carried out by ...

Extended Black-Box Model of Pantograph-Catenary Detachment Arc Considering Pantograph-Catenary Dynamics in Electrified Railway

IEEE Transactions on Industry Applications, 2019
With the increase of the train speed, the pantograph-catenary (PC) detachment becomes more frequent, which results in more serious PC detachment arc. In order to analyze the influence of PC detachment arc on the train system, several arc models are established. However, these models do not consider the actual PC detachment process.

A pantograph arcing model for electrified railways with different speeds

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017
Pantograph arcing is an unavoidable phenomenon in electrified railways, which not only causes damage to the carbon strip and the catenary contact line but also results in voltage surge and electromagnetic interference. In recent years, there are more cases of pantograph arcing due to the increase in speed of trains.
