摘要
为满足变压器式可控电抗器(controllable reactor of transformer type,CRT)"高阻抗、弱耦合"的设计要求,结合磁集成技术,提出一种结构更为简单、对制作工艺要求更低的CRT实用化本体结构。该结构通过在工作绕组与控制绕组间设置漏磁铁心,使变压器与限流电抗集成在一起构成一个具有"高阻抗"的基本独立单元。将这样多个基本独立单元组合并联构成CRT本体,可实现"弱耦合"。根据对基本独立单元的磁路分析,推导出工作绕组电流的一般表达式以及建立其等效电路,并以实验室样机制作为对象,在MATLAB/Simulink中仿真计算,其结果说明该结构能够满足CRT"高阻抗、弱耦合"的设计要求,验证该结构的适用性及正确性,为样机制作提供参考。
In order to meet"high impedance and weak coupling"design requirements of controllable reactor of trans-former type(CRT),combined with the magnetic integrated technology,a CRT practical noumenal structure with sim-pler structure and lower production process requirements is proposed. The structure integrates transformer with cur-rent-limiting inductance and forms a basic independent unit with high impedance through setting a leakage magnetcore between the working winding and control winding. And combining several basic independent units in parallelconstitutes CRT noumenon can meet"weak coupling". In accordance with the magnetic circuit analysis of the basicindependent units,the general expression of the working winding current has been inferred and the equivalent cir-cuit for the structure has been established.Furthermore,the production of laboratory model machine has been simu-lated in MATLAB/Simulink as an object. Simulation results show that the structure can satisfy the requirement of"high impedance,weak coupling"and the applicability and correctness of the structure has been verified.The struc-ture provides a reference for manufacture of model machine.
