摘　　要：针对工业自动化和国防军事领域同步分解电角度量值溯源需求,提出了一种基于多盘感应比例电桥平衡原理的同步分解电角度校准方法,并组建了一套同步分解标准器校准装置。该装置通过电桥的准电压平衡和不平衡误差电压解算的方法获得同步分解电角度的标准值,并通过相对简单的接线方式,实现同步和分解两种模式下0°~360°电角度的校准。对同步模式下电角度校准装置的不确定度进行了评估,不确定度达到0.000 13°(0.47″)。该方法具有准确度高、操作简单、测量速度快的特点,使同步分解电角度量值溯源到感应电压比例标准。In order to meet the demand of synchro/resolver electrical angle quantity traceability in industrial automation and defense military field,a calibration method based on multi-disk induction ratio and bridge balance principle is proposed and a calibration device is formed for synchro/resolver electrical angle. The standard values of synchro/resolver electrical angle is obtained by the quasi-voltage balance of the bridge and the unbalanced error voltage resolving method,and realizes the calibration of 0 ° ~ 360 ° electric angle in synchronous and decomposition modes through relatively simple wiring mode. The uncertainty of the electrical angle calibration device in the synchronous mode is evaluated, the uncertainty reached 0. 000 13°( 0. 47″) . The method has the characteristics of high accuracy,simple operation and fast measuring speed,and the synchro/resolver electric angle value is traced to the induced voltage ratio standard.
