Abstract

An arc diagnostic system has been developed for analyzing arc motion, structure, and intensity in electrical components such as molded case circuit breakers and contactors. The system utilizes an array of fiber-optic cables and matching photodiode receivers to monitor the light from an arc and convert the light into electrical signals which are acquired by a high speed transient digitizing system. The two unique aspects of this system are in the animation and arc intensity capabilities. Acquired images of the arc (up to 1 image per microsecond) are superimposed on a CAD drawing of the device being tested and reanimated frame by frame on a personal computer screen. Arc intensity is proportional to the spot size shown in the reanimation. The system can also acquire corresponding current, arc voltage, and arc chamber pressure which are correlated to the reanimation. High power short circuit tests were performed on a current limiting molded case circuit breaker (MCCB) to illustrate system capabilities. Discussions about the acquired results are made as well as future refinements to the system.

计算机动画数字电弧诊断系统

电弧诊断系统已开发用于分析电弧运动，结构和强度的电气元件，如模壳断路器和接触器。该系统利用一组光纤电缆和匹配的光电二极管接收器来监测来自电弧的光，并将光转换为电信号，该电信号由高速瞬态数字化系统获取。该系统的两个独特方面是动画和弧强度能力。获取的弧线图像(每微秒最多1张图像)叠加在被测设备的CAD绘图上，并在个人电脑屏幕上逐帧重新显示。电弧强度与再现图中显示的光斑大小成正比。该系统还可以获取与再激活相关的相应电流、电弧电压和电弧室压力。对限流塑壳断路器(MCCB)进行了大功率短路试验，以说明系统性能。讨论了获得的结果，并对系统进行了进一步的改进。
