摘要: 场磨式电场传感器常被用来测量特高压直流(HVDC)输电线路下地面合成电场强度.传统对其标定的方法存在标定装置体积较大、户外标定移动不方便的缺点.针对此问题研究了一种应用于特高压直流输电线路下地面合成电场测量的电场传感器便携式缩尺标定装置.基于有限元方法建立了传感器的三维电场模型,基于该模型对便携式标定装置的尺寸、结构等关键参数做出了模拟分析,在此基础上进行了便携式标定装置的结构参数的优化设计.将便携式缩尺标定装置与标准的标定装置进行了实验比较.仿真及实验结果表明该标定装置能够方便、准确地对场磨式电场传感器进行标定.

Abstract: Field mill type electric field sensors are widely used to measure the total electric field at ground level under the high voltage direct current (HVDC) transmission lines. The size of the traditional calibration device is extremely large and it is not very convenient to move for outdoor measurement usage. To overcome this disadvantage, a new kind of reduced scale calibration device with preferable portability was elaborated applied in measurement of the total electric field at ground level under the high voltage direct current transmission lines. The finite element analysis method was employed to establish the three dimensional model of the electric field sensor calibration device. The numerical simulation analysis based on the finite element method was made with the respect to the dimension and structure and other key parameters for the portable calibration device. The structure parameter of the calibration device was optimally designed based on the simulation result. In addition, the reduced-scale portable calibration device was compared with the traditional calibration device by experiments. Based on the experimental and the simulation results, the proposed portable device demonstrates that it can accomplish the accurate and flexible demands of the electric field calibration.

Key words: HVDC power transmission, field mill type electric field sensors, calibration device, finite element analysis, electric field measurement
