Analysis of Parameters Influence on the Characteristics of Thomson Coil Type Actuator of Arc Eliminator Using Adaptive Segmentation Equivalent Circuit Method

Abstract

-A Thomson coil type actuator is applied as the driving unit in an arc eliminator system. To eliminate the arc efficiently, the speed of the actuator is required as fast as possible with certain limit of the exciting current. Therefore, the dynamic characteristics of the Thomson coil type actuator should be analyzed in an effective way. In this paper, a novel solving technique has been developed based on the equivalent circuit model which is set up by dividing the conducting plate into multi segments. To guarantee the calculation accuracy and improve the calculation efficiency, an adaptive refinement algorithm is suggested based on the field continues condition. The proposed method has been verified by the FEM calculation and experiment. The influence of circuit and plate parameters to the performance of the actuator is also investigated, from which a reasonable set of parameters can be found.

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

“…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]. More research and work about the influence of parameters on the performance of the actuator have been done by using ECM in [8, 9, 10].…”

Shape Optimization of a Thomson Coil Actuator for Fast Response Using Topology Modification

“…Furthermore, all the segments move together as a whole plate, the derivative of mutual inductance between two segments is also zero. In this paper, the inductance is calculated by using a method based on Bartky's transformation [4]. The energy W and electromagnetic force F e can be calculated as follow:…”

Closing performance of the Thomson‐coil actuator for a 110 kV FMS

“…The recent researches mainly focus on the opening drive and damping methods, and there is little research on the closing operation. To analyse and simulate the operating process of TCA, there are mainly two methods: finite element method (FEM) [4–8] and equivalent circuit method (ECM) [9–11]. Since FEM is quite time‐consuming and is not suitable for parameter optimisation, in this paper, research and work about the influence of parameters on the closing operation have been done by using ECM.…”
