旋转变压器转角及幅值的微机测量系统

The Computer Measurement System of Rotating Transformer's Angle and Amplitude

旋转变压器的转角及幅值测量系统采用嵌入式微机，通过整形电路、鉴相电路和脉冲填充法计算出定 子和转子相位角，利用采样保持器、A／D转换器测量出幅值的大小，实现对角度和幅值的实时测量与显示．

The rotating transformer's angle and amplitude measurement system adopts the embedded computer, wave-shaping circuit phase discrimination circuit and pulse filling method to calculate the phase angle between the stator and the rotor, and adopts the sampling keeper and A/D transformer to measure the amplitude and to realize the real time measurement and display of phase angle and amplitude.
