摘　　要：根据相关电器产品安全标准的要求,研制了一种可实现低测量误差的剩余电压检测仪器.该装置通过掉电识别电路判断系统掉电,在单片机的控制下实现掉电1 s和10 s后剩余电压的在线检测.实验结果证明该装置有较好的稳定性,测量准确度达到0.5%,满足测量要求.An apparatus used to detect residual voltage with low measurement errors is developed in accordance with certain relevant safety standards. The measuring equipment can distinguish power down by means of power down monitoring circuitry, the residual voltage is measured online at the moment of one second and ten second after power down under control of singlechip. Experimental result proves that the metering equipment has good stability with accuracy of 0. 5%, and meets the measurement requirements.
