摘要
为解决互感器负荷箱测量仪同相分量和正交分量的校准问题,在分析互感器负荷箱测量仪工作原理的基础上,设计了基于电子/电工组合式的互感器负荷箱测量仪校准装置,并简要说明装置电工部分、电子部分以及上位机软件的实现。经省级计量研究院验证结果表明,该装置校准结果符合0.2级要求,可作为标准装置解决1级互感器负荷箱测量仪量值溯源问题。
A calibration device based on electronics / electrical combination is designed for testing instruments on load box of instrument transformers. It aims to calibrate the in-phase components and quadrature components of the testing instruments on load box of instrument transformers,and analyzes the working principles of the testing instruments. This paper discusses briefly the electrical section,electronics section and the realization of the PC software. The verification results of a provincial institute show that the device calibration results conform to the requirements of the magnitude 0. 2,and the device can serve as a standard in the value traceability of first-level testing instruments on load box of instrument transformers.
