摘要
针对双脉冲测试平台对电抗器紧凑化、小型化的需求,本文设计了一种环形空心电抗器,旨在解决传统螺线管型和干式空心电抗器磁场泄漏严重的问题。电抗器采用利兹线绕制,并基于等效电流环理论优化结构设计,通过理论分析和Ansys等电磁场仿真软件计算电抗器的电感值、寄生参数并验证其绝缘性能、热稳定性和动稳定性。基于其双层绕组结构,可提供3个电感值供使用。结果表明,环形空心电抗器具有高储能密度、低磁场泄漏和良好的稳定性,其储能密度约为传统螺线管型电抗器的28.389倍,且在双脉冲测试中表现出色。结论表明,该电抗器设计满足双脉冲测试平台的发展需求,可作为其紧凑化、小型化的重要技术手段。
To meet the requirements of compactness and miniaturization for double-pulse test platforms,this paper proposes a design of a toroidal air-core reactor to address the severe magnetic field leakage issue associated with traditional solenoid and dry-type air-core reactors.The reactor is wound with Litz wire and optimized based on the equivalent current loop theory.The inductance value and parasitic parameters of the reactor are calculated through theoretical analysis and electromagnetic field simulation software such as Ansys,and its insulation performance,thermal stability,and dynamic stability are verified.Based on its dual-layer winding configuration,the reactor offers three selectable values to accommodate diverse testing scenarios.The results show that the toroidal air-core reactor has high energy storage density,low magnetic field leakage,and good stability,with its energy storage density being 28.389 times higher than that of traditional solenoid reactors.The reactor performs well in double-pulse testing.The conclusion indicates that the proposed reactor design meets the developmental requirements of double-pulse test platforms and can serve as an important technical means for their compact and miniaturized development.
