Assessment of the Current Collection Quality of Pantograph-Catenary with Contact Line Height Variability in Electric Railways [PDF]

open access: yes, 2021
The numerical tools are widely used to facilitate the design of the railway catenary. Only radical results are obtained as the current assessment is generally performed without any practical errors.

A Supercapacitor-Based Method to Mitigate Overvoltage and Recycle the Energy of Pantograph Arcing in the High Speed Railway

open access: yesEnergies, 2019
The pantograph arcing phenomenon may shorten the service life of a pantograph and even destroy onboard devices and instruments, due to the irregular motions of the train and the intermittent line–pantograph disconnection. This paper points out that

Characteristics of pantograph‐catenary arc under low air pressure and strong airflow

open access: yesHigh Voltage, 2022
Pantograph‐catenary arc fault is the primary factor threatening the stability of the power transmission for high‐speed railway. The motion characteristics of the pantograph‐catenary arc under low air pressure and strong airflow is significantly different

Cluster Analysis Based Arc Detection in Pantograph-Catenary System [PDF]

open access: yesJournal of Advanced Transportation, 2018
The pantograph-catenary system, which ensures the transmission of electrical energy, is a critical component of a high-speed electric multiple unit (EMU) train. The pantograph-catenary arc directly affects the power supply quality. The Chinese Railway High-speed (CRH) is equipped with a 6C system to obtain pantograph videos. However, it is difficult to

Study on abnormal abrasion of metro pantograph

open access: yes机车电传动, 2023
Pantograph-catenary system is the central system for the power supply of urban rail transit trains. Higher train speed and complex train operating environment can generate severe vibrations on the pantograph-catenary system, resulting in high-frequency ...

Application of GWO-SVM Algorithm in Arc Detection of Pantograph [PDF]

open access: yesIEEE Access, 2020
High-speed train will produce pantograph arc during the driving process, which is harmful to pantograph-catenary system. In order to reduce pantograph-catenary system damage, a method based on Gray Wolf algorithm to optimize the binary Support Vector Machine classifier to identify pantograph arc is proposed.

Clustering techniques applied to a high-speed train’s pantograph–catenary subsystem for electric arc detection and classification [PDF]

open access: yes, 2016
Assessment of the current collection properties of a pantograph–catenary system mounted on a train is of great importance. Excessive electric arcing can lead to wear of the system’s components, and, at the same time, it can be an index of wear status. In
