摘要
本文论述了320千安匝直流大电流仪器仪表精密校验装置设计原理。该装置的电流量程可达320千安匝,主电源稳定度为0.02%h~(-1),辅助电源稳定度为O.003%h~(-1),标准比较仪电压输出精度为0.01%。电压测差法系统误差<0.02%,电流测差法系统误差<3×10~(-6)。
The design principle of a precision calibrating-testing device for up to 320 kilo-ampere-turns is described. The stability of the main power supply is 0.02% per hour and that of the auxiliary power supply is 0.003% per hours. The accuracy of voltage output of the standard comparator is 0.01%. The errors in voltage difference and current difference measuring systems are less than 0.02% and 3×10-8, respectively.
