摘　　要：利用有限元软件ANSYS的电磁分析功能,对一种基于石英晶体的逆压电效应,采用模间干涉原理的全光纤电压互感器的传感头内部电场进行分析与计算,进而对传感头的结构进行设计与优化,使传感头内部的电场分布尽可能均匀,防止尖端放电和介质击穿现象的发生,提高了光纤电压互感器的绝缘性能。为光纤电压互感器电压测量的安全性和稳定性提供了理论依据。Based on the converse piezoelectric effect of quartz,a novel dual-mode interference,a full optical-fiber voltage transformer was presented.The electric field of full optical-fiber voltage transformer was analyzed and investigated by using ANSYS.The structure of transducer probe was designed and optimized so that the internal electric field distribution uniformity as far as possible to prevent point discharge and dielectric breakdown.The insulation capability of voltage transformer is improved.Thus it provides a theorotical foundation for security and stability of voltage measurement by this voltage transformer.
