摘　　要：开发了一套带有四个模拟通道的二维光纤快速摄像系统,用于研究塑壳断路器中高速运动的高温电弧等离子体。其最大拍摄速度可达106幅/ s,模拟通道可直接测量如电弧电流、电压及压力等物理量。构成测试区域的每根光纤顶端均加装了非均匀介质纤维透镜,可有效解决观测区域重叠的问题,大大提高测量精度。同时软件部分采用发布-订阅对象行为型设计模式,通过建立动态图元与试验数据之间的松散耦合实现了图形组态功能,增强了系统的适用性和灵活性。实现结果表明,系统为研究和提高塑壳断路器尤其是应用气吹来弧技术的新一代断路器的开断性能提供了更先进的精确测试手段。An integrated measurement system for the investigation of high speed and high temperature arc plasma is presented. 2-D optical fiber high-speed imaging system is integrated with four analog channels to gain insight into the complex arc plasma in molded case circuit breakers. The imaging system captures at a rate of 106 images per second. The analog channels permit direct measurement to obtain transient signal, such as arc current, voltage and pressure. To improve the spatial resolution of optical fibers, lens with inhomogeneous dielectric is fixed on the top of each fiber. The Publisher-Subscriber behavioral design pattern is applied to the software and the loosely coupled relationship between glyph and experimental data is once established, the graphic configuration can be implemented for simulation analysis, and the flexibility and applicability of the whole system are obviously improved. It demonstrates that the system provides a better research technique especially for new-generation MCCB with gas-driven arc.
