摘要

本文介绍了用于电感计算的简化闭式公式，该公式专为涉及极度接近的同轴线圈的情况而定制。这些公式解决了汤姆逊线圈致动器（TCA）等效电路法（ECM）建模中电感计算所面临的挑战，为直流断路器提供了超快的故障电流分断能力。利用这些闭式公式实现的 ECM 模型具有高效、易用和可移植的特点。重要的是，目前实施的多物理场 ECM 模型集成了全面的机械相互作用，为 TCA 的设计提供了基准方法。

Multiphysics Model of Thomson-Coil Actuators With Closed-Form Inductance Formulas and Comprehensive Mechanical Interactions

This paper introduces simplified closed-form formulas for inductance calculations tailored for cases involving coaxial coils in extreme proximity. These formulas address the challenges associated with inductance calculations in the equivalent-circuit method (ECM) modeling of Thomson-coil actuators (TCAs), offering ultra-fast fault current-breaking capability for DC circuit breakers. The implementation of the ECM model using these closed-form formulas features high efficiency, accessibility, and transferability. Importantly, the present implementation of the multiphysics ECM model integrates comprehensive mechanical interactions, providing a benchmark approach for designing TCAs.
