中文摘要:
      叙述了2~500 mV/1 kHz~1 MHz范围内的低电压交直流转换溯源技术,介绍了利用十进制感应分压器在低电压交直流转换技术的量程的扩展上的应用。介绍了基于汤普森方法对十进制感应分压器的设计和校准,并给出了校准的试验数据。同时也描述了一个可抬高电位的,具有一个额外二次绕组的校准用感应分压器的设计和绕制。校正电路和输入输出电压隔离分压器以及N型连接头的设计进一步降低了标准分压器的磁误差。校准系统应用于毫伏级电压和工频下的感应分压器。
英文摘要:
      This paper describes a low voltage AC DC transfer traceability technology at 2-500 mV/1 kHz-1 MHz range, it also describes the use of a decimal inductive voltage divider used for the scale expansion of AC DC transfer technology. Thompson method is introduced in the paper and it gives the experimental data of calibration of IVD. This article also describes the design and winding of a calibration IVD with an additional secondary winding. Correction circuit and input output isolation voltage divider, and N type connector is designed to further reduce the magnetic error. The calibration system is applied at millivolt voltage and industrial frequencies.
