一种新型的交流阻抗计量标准装置

A New Type of AC Impedance Measurement Standard Device

为解决任意阻抗模与阻抗角的交流阻抗的溯源问题,研制了一套新型交流阻抗标准装置,由交流阻抗标准源及交流阻抗标准表组成,在100 Hz^1 MHz、0. 1Ω~1 kΩ范围,可对RLC数字电桥、交流阻抗和实物阻抗进行校准,技术指标可以达到0. 01%。采用直接测量法、替代测量法和等电位测量法,将交流阻抗标准溯源到实物阻抗标准、电压比例标准和相位标准上,形成了一条完整的交流阻抗溯源链。

A new type of AC impedance measurement standard is developed,which can resolve the traceability problem of AC impedance by producing any amplitude and angle. Between 100 Hz to 1 MHz,0. 1 Ω to 10 kΩ,the new type of AC impedance measurement standard,which is composed of AC impedance standard source and meter,can calibrate RLC digital meter, AC impedance and material impedance, and the best accuracy is 0. 01%. By using direct measurement,substitution measurement and equipotential measurement,AC impedance measurement standard can be traced to material impedance standard,voltage ratio standard and phase standard. Thus a traceability chain of AC impedance is formed.
