Modeling pantograph–catenary arcing

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2016
The performance of the pantograph–catenary system plays a significant role in determining the reliability and safety of a high-speed train. With an increase in train speed, repeated separations between the pantograph and catenary result in an increased number of arcing events, which exacerbate the levels of damage on the pantograph–catenary system ...

Dynamics of Pantograph–Catenary Arc During the Pantograph Lowering Process

IEEE Transactions on Plasma Science, 2016
Pantograph–catenary (PC) arc has become an obstacle for the further development of high-speed railway. Understanding on the underlying physical mechanisms of PC arc dynamics is still far away from satisfactory; therefore, researches from both experimental and numerical aspects are urgently required.

Visual Detection Approach of Pantograph-Catenary Arcing Based on Dense Mesh Learning

International Conference on the Software Process, 2023
Pantograph-catenary system is an important part of the railway train. The appearance of offline arcs at the contact point between pantograph and catenary will affect the stability of train current collection. Accurately identifying the occurrence of arcs

Magnetic Components Used in the Train Pantograph to Reduce the Arcing Phenomena

IEEE Transactions on Industry Applications, 2013
In the power supply system of an electrified railway, a pantograph in contact with the overhead train line is used to send electricity to the main transformer of the electric train, thus providing power. However, due to many external influences, such as the shaking caused by high-speed driving, the bouncing and contact friction between the pantograph ...
