摘要:
本文提出一种自动化校准系统用于高压交流分压器(30~300 Hz)等高压计量仪器的自动化检测。装置的输出电压为0~200 kV，波形畸变率低于1%，并且输出正弦电压波动值小于0.1级，频率误差小于0.01 Hz。自动化校准系统输出高压电源幅值和频率非常稳定，且整个检测和校准过程全自动。实际应用表明该交流分压器自动化校准系统可以大大提高分压器等高压计量设备校准过程的准确性，降低检测结果的不确定度。
An automatic calibration system is designed to make calibration for AC high voltage divider (30 - 300 Hz). The maximum output of the automatic calibration system is 200 kV. The distortion of the high voltage is less than 1% and the frequency error is less than 0.01 Hz. The readings error of the automatic calibration system is Level 0.1. The voltage and its frequency are very stable. The whole calibration procedure is automatic. The application of the automatic calibration system can increase the quality control of high voltage system calibration in the laboratory and decrease the uncertainty of measurement result.
