摘　　要：相对于前几代断路器,CW2(P型)系列智能型万能式断路器增加了电参量测量分析功能,在出厂检验时必须对产品的电参量测量分析功能进行测试。设计了一套以工业控制计算机为核心,配置高精度数据采集卡和信号调理电路等硬件,采用先进的虚拟仪器技术——LabVIEW 7 Express软件开发平台自行开发数据采集、分析、处理软件,通过PCI标准总线组成的高度集成的动态电参量自动测量分析系统,可满足智能型万能式断路器产品的出厂检验要求。详细分析了系统总体方案设计,具体阐述了系统软件模块设计。经实际应用表明:该系统具有测试精度高、抗干扰能力强、检测效率高、操作简单等优点。Relative to former generations of breaker, the measurement and analysis function of electric parameters which must pass the ex-factory test has been added for CW2 series intelligent conventional circuit breaker. This paper designed a new dynamic electric parameters measurement and analysis system consisting of industrial computer, data acquisition board, signal modulate board and software developed by LabVIEW virtual instrument technology. The system can satisfy the demands of CW2 series intelligent conventional circuit breaker ex-factory test. The system structure and module design of system software were introduced in detail. The system has the properties of high precision, strong disturbance attenuation, high efficiency and convenience manipulate.
