摘要:
提出一种以磁路转移为技术手段的电感调节原理,利用直流磁通迫使交流磁通改变流通路径,达到磁路转移的目的,进而改变交流等效磁阻实现电感值连续无级可调。结合磁路基本理论详细分析调节过程,给出3 种情况下电感计算模型; 用有限元法仿真计算电抗器的磁场分布; 设计直流控制电路及参数; 制作一台实验样机,测试电感调节特性。仿真和实验结果证实了此原理的正确性。结果表明: 电感值与补偿系数呈反比例函数关系,且补偿系数越小,电感值变化越明显; 不补偿时,交流等效磁阻最小,电感值最大; 全补偿时,交流等效磁阻最大,电感值最小; 电感调节倍数取决于大气隙与小气隙的比值。
Abstract:
 An inductance adjustment theory based on magnetic circuit transfer is proposed. By using DC magnetic flux to compel AC magnetic flux to change its circulation path,the magnetic circuit transfer was achieved,so that the AC equivalent reluctance was changed and the inductance value was adjusted continuously.Its working process was analysed in detail combining with magnetic circuit basic principles and inductance mathematical expressions in 3 conditions were provided. Finite element method was used to simulate the reactor’s magnetic field. DC controlling circuit and its parameters were designed. A prototype was made to measure its inductance adjustment feature. Simulation and experimental results confirmed the correctness of this theory. Results show that the relationship between inductance value and compensation coefficient is an inverse function. The less compensation coefficient is,the more obviously inductance value changes. When it is not compensated,the AC equivalent reluctance is minimum and inductance is maximum; while the AC equivalent reluctance is maximum and inductance is minimum when it is fully compensated. The ratio of maximum and minimum inductances depends on that of large air-gap and small air-gap.
