摘要

由于高压互感器绝缘设计较为困难,使得现有的标准电压互感器测量准确度难以得到有效的提升。该文以多级高低压混合励磁标准电压互感器电路为研究对象,结合多级励磁理论进行该电路在理想条件下的仿真分析。首先,根据该励磁方案建立其对应的等效电路;其次,根据该等效电路推导出互感器准确度计算公式;然后,结合实际需求,对${500}/{\sqrt{3}}\;\text{kV}$多级高低压混合励磁标准电压互感器进行理论参数计算,包括内阻抗与励磁阻抗参数计算;最后,根据上述的理论参数计算出该互感器的测量准确度,仿真结果表明该互感器结构的比差为-2.27×10^-7%,角差为3.44×10^-6%,该标准互感器足以满足准确度等级为0.002级的要求,可尝试开发实物。

Abstract：

Insulation design of high voltage transformers is too difficult to effectively improve the measurement accuracy of existing standard voltage transformers. In this paper, the circuit of standard voltage transformer with multistage voltage hybrid excitation, both high and low voltage are included, was studied through simulation analysis under ideal conditions combining with multistage excitation theory. Firstly, the equivalent circuit of high voltage transformer was established according to the excitation scheme; secondly, evaluation formula of measuring accuracy were derived according to the equivalent circuit. Then, in combination with the actual demands, the theoretical parameters of voltage transformer at ${500}/{\sqrt{3}}\;\text{kV}$ with multistage voltage hybrid excitation were calculated, including the calculation of the internal impedance and the calculation of the excitation impedance. Finally, according to the calculation results of the above theoretical parameters, the measurement accuracy simulation values of the transformer were given. The simulation results show that the ratio error of the transformer structure is -2.27×10^-7% and the angle error is 3.44×10^-6%, which meet the accuracy level requirements of 0.002 greatly. And it can be tried to develop physical objects with these parameters.

Key words： Multistage excitation standard voltage transformer internal impedance excitation impedance angle error ratio error
