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。

In order to realize design principle of controllable reactor of transformer type (CRT)-“high impedance, weak coupling”, a magnetic integrated structure of CRT was proposed based on magnetic integrated technology. Its work winding was made of multiple sections in parallel according to power step and pancake type was employed in all windings. Each section work winding and a control winding constitute a basic unit of structure. In order to realize “high impedance”, the iron-cake was installed between work winding and control winding. Split core was installed among basic units to realize“weak coupling”. Based on ANSYS,“magnetic field and circuit” coupling method was used to calculate finite element example of magnetic field and current for magnetic integrated structure. Calculation results show that the magnetic integrated structure can satisfy the requirement of “high impedance, weak coupling” and the correctness of this structure is verified. The method of magnetic integrated in this paper provides a reference for further application of the integrated magnetic technology in electrical equipment.
