新型电子式电能表用锰铜分流器的设计方法

Research on the Method to Design Manganin Shunt for New Electronic Energy Meter

传统电子式电能表电流采样部分中的锰铜分流器在受到电磁干扰时,会产生计量误差,给用户以及电网公司造成影响。为了克服传统电子式电能表抗磁场干扰技术的不足,在分析造成计量误差的原因后,提出了一种新型的锰铜分流器结构,通过对传统锰铜分流器结构的改进,使其能够抵抗来自不确定方向磁场干扰,从而保证电子式电能表计量的准确性。

When the manganin shunt used in current sampling part of electronic energy meter will produce measure- ment error in electromagnetic interference environment. A new structure of manganin shunt is proposed after analyzing the reason caused the measurement error to overcome the lack of anti-electromagnetic interference of traditional electric energy meter. Through the improvement of the structure, it is possible to resist the interference of uncertain direction electromagnetic, so as to ensure the accuracy of measurement.
