| 锰铜分流器作为单相智能电能表的电流采样装置，在工频外磁场干扰下会产生感应电流，影响电能表计量的准确性。提出了一种基于稳健设计理论的锰铜分流器结构优化设计方法，提高锰铜分流器抗磁场干扰能力。首先，理论分析了锰铜分流器在外加工频磁场干扰下产生感应电流的基本原理，并基于Flux软件建立了锰铜分流器感应电流仿真模型；进而，基于正交试验设计对影响感应电流大小的因素进行信噪比分析，确定显著因素作为后续优化目标，采用Taguchi稳健设计方法对锰铜分流器进行优化设计；最后通过蒙特卡洛仿真对优化前后感应电流大小一致性评价，验证了稳健设计方法在提高锰铜分流器抗磁场干扰能力的适用性。 |

| As a current sampling device of single phase intelligent watt hour meter, manganese copper shunt will produce inductive current under the interference of external magnetic field of power frequency, which will affect the accuracy of watt hour meter measurement. In this paper, an optimal design method of induced current of manganese copper shunt is proposed based on robust design theory. Firstly, the basic physical principle of induced current produced by manganese copper shunt under the interference of power frequency magnetic field is analyzed theoretically, then the simulation model of manganese copper shunt is established based on Flux software. Afterwards, design of experiment (DOE) based signal noise ratio (SNR) analysis is carried out to rank the influence factor for induced current. Then, the optimal design of manganese copper shunt is carried out based on Taguchi robust design method. Finally, the induced current before and after optimization is compared by Monte Carlo simulation consistency evaluation. It is proved that the robust design method is suitable for improving the magnetic field interference ability of the manganese copper shunt. |
