| 摘 要： | 为了提高光学电压互感器的测量精度,提出了提高其稳定性的方法。工作时,高电压直接作用在Pockels电光晶体BGO上,特别是基于双光路技术的光电传感元件OPS用作检测具有很多优点,抑制了电场扰动而提高了灵敏度。然后,对以DSP为核心的数字电路和软件设计进行了深入的研究。这样,这种OPS的稳定性(特别是温度稳定性)、灵敏度和线性得到明显提高。最后对OPT进行了精度检测,能实现0.2%的精度要求。

| Abstract: | In order to raise the precision of measurement, a method for improving stability of Optical Potential Transformers (OPT) is proposed in this paper. A high voltage is directly applied on Pockels elector-optic crystal BGO. The OPS based on bi-light path technique has an attraction for measurement. It has high sensitivity and high immunity to electric interference. Furthermore, the digital circuit by DSP and the software design are studied. The results show that the OPS stability (especially under high temperature), sensitivity and linearity are obviously raised. A strict test of OPT shows that its precision obtains 0.2%. |
