摘　　要：安全、准确获取电力系统的电参量数据可保障电力系统安全稳定运行。相比于传统的电压测量,非接触式测量技术因无需与一次设备有直接的电气连接而具备更高的安全性,同时具有体积小、频带宽、瞬态响应特性好等特点,可以满足现代电网分布式传感网络的需求。详细介绍耦合电容式电压传感、基于电流积分法的电压传感、D-dot电场传感、基于电光效应、压电效应、静电力效应的电场传感等技术,分析上述感知方法的优势及存在的问题,同时介绍电场反演电压的方法。最后对非接触式电压/电场传感技术进行了总结并就发展前景进行了展望。Safe and accurate acquisition of electrical parameter data of the power system can ensure the safe and stable operation of the power system.Compared with traditional voltage measurement,non-contact measurement technology has higher safety because it does not need to have a direct electrical connection with the primary equipment,and has the characteristics of small size,frequency bandwidth,and good transient response characteristics,which can meet the needs of modern power grid distributed sensor networks.This paper introduces in detail the technologies of coupling capacitive voltage sensing,voltage sensing based on current integration method,D-dot electric field sensing,electric field sensing based on electro-optical effect,piezoelectric effect,and electrostatic induction effect,analyzes the advantages and existing problems of the above sensing technology,and introduces the method of electric field inversion voltage.Finally,the development prospect of non-contact voltage/electric field sensing technology is prospected.
