基于LabWindows/CVI的电子式互感器数字输出分析仪

Electronic Transformer Digital Output Analyzer Based on LabWindows/CVI

介绍了电子式互感器的数字输出,并针对当前没有专门工具检测分析合并单元数字输出帧的情况,在LabWindows/CVI虚拟仪器平台上开发了一种数字输出分析仪,利用以太网卡采集电子式互感器合并单元数字输出信号,对信号进行分类与重组,实现波形显示、数据存储与分析等功能。实验表明,该仪器分析和处理的结果真实可靠并且成本低、设计简单、操作方便,是实验室开发电子式互感器合并单元的有效测试工具。

Up to now, there are no special tools to analyze and detect the digital output of combination unit. This paper introduced the digital output mode of electronic transformer, and developed an analyzer based on LabWindows/CVI. The analyzer acquired signals from the transformer＇ s digital output port by network interface card, sorted and recombined the signals, and finally realized displaying waveform, saving and analyzing data etc. functions. The analyzer is an effective testing tool for developing the electronic transformer combination unit in laboratory.
