Magnetically Integrated Structure for Transformer-Type Controllable Reactors: Magnetic Circuit and Circuit Analysis

摘要

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，利用磁集成技术提出了一种CRT本体结构.首先，通过在工作绕组与控制绕组之间设置漏磁铁芯，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，再将多个基本独立单元并联构成CRT本体，实现弱耦合的设计要求；其次，在构成的结构基础上建立了其等效磁路和等效电路模型，详细分析了不同工况下主磁通与漏磁通的分布情况，推导了揭示电流变化与磁通变化之间内在联系的电流计算公式；最后，在此基础上，针对一个控制绕组额定电流分别为10、15、20 A的单相3级CRT进行了仿真计算.仿真结果表明：当各控制绕组依次单独短路时，工作绕组电流分别为9.997、24.540、43.900 A，与其额定电流值基本相同；已工作的控制绕组短路电流未因后续投入工作的控制绕组而改变，说明了该结构能够满足CRT高阻抗、弱耦合的设计要求.

Abstract: In order to meet the high impedance and weak coupling design requirements of controllable reactors of transformer type (CRT), a practical CRT body structure is proposed, based on magnetic integration technology. First, the paper presents the new structure. By using a leakage magnet core between the work and control windings, the proposed structure integrates the transformer and the current-limiting inductance together, thus forming a basic, independent, high-impedance unit. Several of these basic independent units are then combined in parallel to form the CRT body, which meets the weak coupling design requirement. Second, the distributions of both the main and leakage magnetic fluxes are analyzed in detail under different working conditions, by establishing the equivalent magnetic circuit and equivalent circuit models. The current calculation formula is deduced, and the relationship between the current and flux distribution is revealed.Based on this analysis, a single phase CRT whose control windings' rated currents are 10A, 15A, and 20A respectively is simulated and calculated. The obtained simulation results show that, when the control windings are short-circuited in sequence, the work winding currents are 9.997 A, 24.540 A, and 43.900 A, which are fundamentally the rated current values. the short-circuit currents of the operating control windings do not affect the other control windings operating. The proposed CRT structure can meet the high impedance and weak coupling design requirements.
