摘　　要：介绍传统互感器校验仪检定装置采用的标准比例电源输出的电压信号质量易受干扰影响,致使准确性与稳定性得不到保障的问题,在标准电压功率源电路中增加了具有负反馈测量及调整的电路,达到了输出监控及自动控制输出信号准确性的效果,有效提升了互感器校验仪自动整检装置的准确性和稳定性。The traditional standard transformer calibrator uses the standard proportion, the output voltage signal quality is easily affected by interference, so that accuracy and stability can not be guaranteed. This design in the standard voltage of the power source circuit with negative feedback circuit is added in the measurement and adjustment, achieve output monitoring and effect of automatic control output signal accuracy, improve the automatic calibrating device of transformer calibrator accuracy and stability.
