Modelling Thomson Coils With Axis-Symmetric Problems: Practical Accuracy Considerations

Performance of high‐power thomson coil actuator excited by a current pulse train

“…In order to assess the effects that a double discharge may induce in the operation of the TC, an axis‐symmetric, 2D FEA model of the device is employed. It has been demonstrated that a properly compensated 2D axis‐symmetric FE TC model is able to reproduce with high fidelity the physical behaviour of the device [10]. COMSOL multi‐physics 5.3 software is used for the FE simulations in this research and a deformable moving mesh is employed to accurately account for armature displacement and bending.…”

“…For comparison, Fig. 8 shows the armature mean velocity derived from the system kinetic energy [10], where the velocity signal is considerably smoother than that shown in Fig. 6.…”

Research on a novel drive unit of fast mechanical switch with modular double capacitors

“…D.S. Vilchis‐Rodriguez, Ara Bissal, and others have already done some very detailed work on the operational efficiency of the TCA and the practical accuracy considerations by using FEM [3, 4, 5]. However, FEM is quite time‐consuming, which has been proven precise to solve the simulation of a 2D finite element (FE) transient axis‐symmetric model of a TCA [6, 7].…”

Analysis, Design and Dynamic Simulation of Novel Limited Swing Angle Torque Permanent Magnet Motor for High Voltage Circuit Breaker Application

“…20 20 In [33][34][35][36], different permanent magnetic actuators were presented to improve efficiency, reliability and other performance factors. Ref [5,6,37,38] used the monostable and bistable Thomson-coil actuator (TCA) to increase the rapidity, reduce the complexity and improve the reliability of a high-voltage circuit breaker. Many problems still need to be solved in relation to operating mechanism with TCA, such as the problem of contact bounce.…”
