摘要

在非均匀场条件下，观察了环己烷中阴极-流光的引发过程。对半径为0.5 /spl mu/m的钨针施加脉冲电压。用高倍率、高速影印系统对流光生长进行了拍摄。确定拖缆起始电压为-5.18 kV。最初的流光结构是丝状的。在起始100ns内，它变为灌木状结构，随着电压的增加而增加，直到出现二次茎，并重复该过程。在它们的膨胀过程停止后，人们注意到它们会破裂成小气泡。局部放电(PDs)测量使用LED(发光二极管)电流测量系统。讨论了PD与流子生长的关系

Observation of cathode streamer initiation in dielectric liquids under high magnification

The cathode-streamer initiation process in cyclohexane under nonuniform field was observed. An impulse voltage was applied to a tungsten needle of 0.5 /spl mu/m radius. The streamer growth was photographed using a high-magnification, high-speed shadowgraph system. The streamer initiation voltage was determined to be -5.18 kV. The initial streamer structure was filamentary. Within 100 ns of inception it changed to a bushlike structure which increased with increasing voltage until a secondary stem appeared and the process appeared to repeat itself. After their expansion process stopped they were noted to break into small bubbles. Partial discharges (PDs) were measured using an LED (light-emitting diode) current measurement system. The relation between PD and streamer growth is discussed.<>
