高频双通道旋转变压器的计算机测试

High frequency double channel rotary transformer computer test

本文介绍了一种行旋转变压器粗精级电气误差、粗级零位误差测试的计算机测试系统,采用高精度光学分度头作为机械角位置标准,使用国外最新的双通道角位置指示器(API)作为电气角零位定位,通过计算机进行数据采集、计算和最终数据输出。本系统仪器连线简单,软件功能完善,提高了对高频、多对极旋转变压器电气误差的测试精度。

This paper introduces a kind of coarse fine gradeelectrical error,rotary transformer coarse zero error testing ofcomputer test system,high precision of optical dividing headas mechanical angular position using the new standard,high frequency and high precision double channel angle position indicator(API)as an electrical angle zero position,are data acquisition,calculation and final test record output by computer.The system of instrument connection is simple,the software function is perfect,improve the test precision high frequency,multi amtipodal rotary transformer electrical error.
