研究目的
Investigating the influence of imperfect fiber splicing angle and length difference between the sensing fiber and the compensating fiber on the system output performance of a fiber voltage sensor based on the converse piezoelectric effect.
研究成果
The research demonstrated that different fiber splices have varying effects on the system output, with the 90(cid:2) splice being particularly sensitive to angle deviations. The study also highlighted the strict requirements on fiber length difference for high test voltages, suggesting the need for error suppression schemes to improve measurement accuracy. The findings provide a theoretical basis for the production of optical fiber voltage sensors and contribute to the design of intelligent inspection robot systems for power systems.
研究不足
The study is limited by the practical difficulties in achieving perfect splice angles and zero length difference between the sensing fiber and the compensating fiber in actual production. Additionally, the influence of external environmental factors on the sensor's performance was not fully addressed.
