【摘要】：为实现变压器式可控电抗器(controllable reactor of transformer type,CRT)"高阻抗、弱耦合"的设计原则,结合磁集成技术提出了一种变压器式可控电抗器磁集成结构,其工作绕组根据功率级数由多段绕组并联组成,所有绕组均采用饼式结构。每段工作绕组与一个控制绕组组成结构基本单元,工作绕组与控制绕组间设置有铁饼以实现"高阻抗",各基本单元间设置分割铁心以实现"弱耦合"。基于ANSYS软件,采用"磁场-电路"耦合法对磁集成结构的磁场和电流进行有限元算例求解,其结果说明此结构能够满足CRT"高阻抗、弱耦合"的设计要求,验证了此结构的正确性。这种磁集成方法为磁集成技术在电力设备中的进一步应用提供了参考。
[Abstract]:In order to realize the controllable reactor of transformer type (controllable reactor of transformer type, CRT) high impedance, the design principle of weak coupling ", combined with integrated magnetic technology presents a controllable reactor of transformer type integrated magnetic structure, the winding according to the power series composed of a plurality of windings in parallel form, all winding adopts a cake each structure. A working winding and a control winding structure is composed of the basic unit, the discus in order to achieve the" high impedance "set winding and control winding, the basic unit is arranged between the core segment in order to achieve the" weak coupling ". Based on the ANSYS software, using the field circuit coupling of integrated magnetic structure of magnetic field and current finite element numerical solution, the results show that this structure can meet the CRT design requirements of high impedance, weak coupling, verify the correctness of this structure. The magnetic integration method for magnetic integration technology in power The further application of the equipment provides a reference.
