IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

High Voltage, Volume 9, Issue 6, Page 1302-1310, December 2024.Abstract High‐strength copper contact wire is of great significance to the electrified railway power supply system, which constantly provides electric power to the trains during operation. However, contact wire is subject to pressure, vibration, and natural forces such as wind, rain, ice, etc.

Research of simulation and experiment on arc characteristics of gas mechanical switch
High Voltage, Volume 9, Issue 3, Page 626-635, June 2024.Abstract An arc is the high‐temperature discharge plasma produced in the opening process of mechanical switches, which directly affects the breaking capability of a hybrid DC circuit breaker. According to the physical mechanism of an electric arc, the construction of an arc model for simulation analysis is an important technical means in the electrical
