摘要
针对传统浪涌电压检测台无法准确捕获电压瞬态变化,且记录结果难于进行统计分析的不足,开发了一套基于PXI总线以虚拟仪器技术为核心的新型浪涌电压检测台。给出了负载自动投切电路的设计,及通过抛物线插值法实现浪涌电压检测的方法。实际应用表明,该系统具有自动化程度高、测量准确快捷、操作简便等特点。
The traditional surge voltage test-bed couldn＇t capture and record voltage transients,and the results are difficult to carry on statistical analysis.To overcome the above deficiency,a new set of surge voltage test-bed is developed based on VI technology,and the design of load switching circuit and surge voltage calculation algorithm based on parabolic interpolation method are presented.Practical application shows that the system has a high degree of automation and is easy to be operated,at the same time the measurement result is accurate.
