摘　　要：变压器绝缘纸板微水分介电测量系统中,电容式传感器电极与被测绝缘纸板的接触状态及接触压力会影响测量结果。针对这个问题,以绝缘纸板为被测对象,用平板式电容传感器测量压力对其介电参数的影响。并利用ANSYS软件对施压前后的电路变化进行分析,得出了压力对介电响应测量结果的影响。The contacting states and contacting presses between the electrodes and the insulating pressboard can affect the moisture measuring accuracy of transformer insulating pressboard. The plate capacitive sensor is used to evaluate the influences of pressure on measuring results of dielectric coefficient of insulating pressboard. The thesis introduces the results of the test and analyzes the causation of the phenomenon.
