| 摘要: |
| 应用磁畴理论分析了基于交直流绕组正交磁化原理的可调电抗器的调控机理．在直流控制绕组通入一定的直流电流，可以降低电抗器铁芯的交流磁导率，进而改变交流绕组的电感量。通过对试验电抗器的实验数据分析处理，证明了理论分析的正确性．并建立了电感量随直流控制电流的变化关系。通过测试，分析了影响电感量调节范围的因素及电抗器在调节范围内的线性特性。 |

| Abstract: |
| Based on magnetic domain theory,the inductance of tunable reactor can be adjusted continuously by injecting DC current into the control winding which is orthogonal with the AC winding. DC control current can lower the permeability of magnetic core and change the inductance of AC winding. The experimental data analysis of a test reactor verifies the theoretical analysis. The mathematic model that reflects the inductance variation with DC control current is established. The linear charac-teristics and factors,which influence the variable range of inductance,are also investigated. |
