摘　　要：介绍了用于电力测量6通道同步采样A/D转换器AD7656的性能特点、工作原理.针对传统有载开关测试存在的测量速度慢、同期性不佳问题,采用AD7656设计了变压器有载开关测试仪.试验表明这种有载开关测试仪,提高了测量速度、改善了测量同期性、降低了系统误差.AD7656 is the latest product of ADI for electric power measurement. It is high in speed,having 6 independent analog inputs with 16-bit A/D simultaneous sampling converter. This paper introduces its performances ,and working principles to solve the traditional problems, such as low measuring speed and poor synchronigation, we designed the testing instrument for on-load tap-changers in the transformer based on AD7656. The result of experiments indicated that this device could enhance the measuring speed, improve the quality of synchronigation and reduce the system errors.
