摘要
本文介绍35kV和110/3^(2╱1)kV工频电压比例标准的建立及其传递方法。它们采用电容分压器的结构,在低电压下用感应分压器校准,在高电压下使用。研究结果表明,这一工频电压比例自校传递系统的测量准确度,对于35kV╱100V变化为1.5×10^(-5),对于(110/3^(2╱1)kV)/(100/3^(2╱1)V)为5×10^(-5)。
The methods of establishment and calibrations of 35kV and 110/1/3kV power frequency voltage ratio standards are described in this paper. The standard is a capacitive divider which is calibrated at low voltage by IVD and used at high operating voltages. Two voltage transformers, used as working standards, belonging to operating voltages of 35kV and HO/ 3 kV respectively are calibrated by the standard established. The results show that the accuracies of the calibration system of power frequency voltage ratio are ±1.5×10-5 and ±5×10-5 for ratios of 35kV/100V and (110/3 kV) (100/3V) respectively.
