提高他励式磁控电抗器响应速度的方法

Improvement of SMCR response

他励式磁控电抗器(SMCR)的励磁及退磁的响应速度均较慢,极大地限制了其应用的范围。介绍了SMCR的结构及工作原理,并分析了影响其响应速度的原因。在此基础上,提出了能有效提高SMCR响应速度的绕组结构,该结构的工作绕组回路中不存在影响工作电流响应速度的直流环流,只要控制电流达到稳定状态,工作电流也进入相应的稳定状态。且在相同的交流工作电压下,改进的SMCR的输出电流与传统SMCR相同。实验验证结果验证了改进结构的合理性和有效性。

The excitation and demagnetization responses of SMCR（Separate excitation Magnetic Control Reactor） are slow,which limits its application. The structure and working principle of SMCR are introduced and the factors influencing its response are analyzed. An improved winding structure of SMCR is proposed to eliminate the DC circulation in its working winding loop ,which effectively enhances the response of its working current. The working current reaches the stable status if once the control current is stable. The improved SMCR has the same output current of the traditional SMCR under the same AC working voltage. The experimental results verify that the structural improvement is rational and effective.
