Research of simulation and experiment on arc characteristics of gas mechanical switch

open access: yesHigh 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

A Numerical Method Based on the Parametric Variational Principle for Simulating the Dynamic Behavior of the Pantograph-Catenary System

open access: yesShock and Vibration, 2018
Based on the finite element method (FEM), the parametric variational principle (PVP) is combined with a numerical time-domain integral method to simulate the dynamic behavior of the pantograph-catenary system. Based on PVP, formulations for the nonlinear

A Reduced Pantograph-Catenary Interaction Model for Efficient Pantograph-Catenary Interaction Dynamic Analysis

open access: yes
The continuous movement of high-speed train results in the pantograph interacting with a long catenary structure. The traditional methods based on the Lagrangian description can only model the whole long catenary structure, which decreases their ...
