中文摘要：
为了实现变压器式可控电抗器（CRT）“高阻抗、弱耦合”的设计目的,基于磁集成技术,提出了阵列式磁集成CRT结构.通过分析此结构各绕组磁通关系以及建立其等效电路,推导出各绕组的短路阻抗与短路电流的计算式,并进行绕组短路阻抗与短路电流的举例计算.磁通分析与举例计算结果表明,所提出的阵列式磁集成CRT结构将控制绕组与限流电感集成在一起,将各控制绕组的短路电流维持在了额定值,在满足CRT“高阻抗”设计要求的同时减少了分立磁件数目;此外,随着后续控制绕组的投入,已经投入运行的控制绕组电流保持不变,即达到了各控制绕组间完全解耦的目的,满足CRT“弱耦合”的设计要求.
英文摘要：
In order to achieve ＂high impedance and weak coupling＂ in the design of controllable reactor of transformertype （CRT）, we put forward an array structure of magnetic integrated CRT based on magnetic integration. Through ana-lyzing the relationship between magnetic flux of windings in CRT and establishing equivalent circuit for the structure, weinferred the formulas of short-circuit impedance and short-circuit current of each winding. An example was given to cal-culate short-circuit impedance and short-circuit current using the formulas. The analysis of flux and calculation resultsindicate that, the proposed CRT structure integrates control windings with current-limiting inductance, which maintainsthe short current of control windings at its rated value, meeting the requirements of ＂high impedance＂ while reducing theamount of discrete magnets. Moreover, the current of control windings which have been put into operation can remain tobe unchanged despite the following input of control windings, that is to say, the complete decoupling between each con-trol winding is achieved, which meets the requirements of＂weak coupling＂ for CRT design.
