摘要

研究了真空断路器电极间隙内低压大电流电弧的金属等离子体所发出的可见辐射。利用快速多通道光分析系统记录了可见辐射的时间演变，该系统提供了足够的空间分辨率，以跟踪在1 kA, 2 kA和10 kA电弧峰值电流下进行的真空电弧发展实验。电压波形和辐射信号的相关分析使得识别与强局部电流-电极相互作用有关的过程成为可能。

Time and space resolved analysis of the visible radiation from a vacuum circuit breaker discharge

The object of the investigation was the visible radiation emitted by the metal plasma of a low-voltage, high current arc occurring in the interelectrode gap of a vacuum circuit breaker. The time evolution of the visible radiation was recorded by means of a fast multichannel light analysis system that provided sufficient space resolution to follow the vacuum arc development in experiments done at 1 kA, 2 kA and 10 kA arc peak currents. The correlated analysis of the voltage waveforms and radiation signals made possible the identification of processes related to strong localized current-electrode interactions.
