摘要:
 在对称环形封闭的差分D-dot电压传感器基础上,提出并设计一种开合式的扇形结构传感器,新传感器保持了良好测量精度与动态范围,安装便利,实用性强。通过ANSOFT Maxwell仿真分析软件基于有限元分析方法完成了该传感器的电容参数计算,根据有、无传感器方向电场分布情况对导杆周围电场畸变小且绝缘裕度高的特点进行了验证。实验制作传感器,在10 kV电压等级下进行了稳态与暂态性能的试验测试。结果表明,该传感器不但在测量稳态电压时波形的失真度与相位误差较小,还对各种暂态波形具有良好的跟踪能力,在不同条件下均能保持较好的工作特性。
Abstract:
A differential D-dot sensor with open fan-shaped structure is designed on the basis of symmet-ric circular closed structure. It not only maintains good measurement accuracy and dynamic range,but isalso convenient to be installed. The sensor’ s capacitance characteristics were calculated by ANSOFTMaxwell simulation software based on the finite-element analysis method,and its characteristics,for ex-ample,slight electric field distortion and high insulation margin,were also verified by analyzing the elec-tric field distribution in the directions of sensor and non-sensor. After the sensors were finished,steadyand transient performance tests were conducted under 10 k V-voltage,
and the results show that the sensornot only remains small waveform distortion and phase error when measuring the steady state voltage,butalso has a good tracking ability for a variety of transient waveforms,keeping satisfactory performance un-der different work conditions.
