摘要

利用光光电流测量技术和760-ns矩形高压脉冲，研究了聚乙烯中点对面间隙结构的电击穿现象。聚乙烯中预击穿电流的波形与液体介质中的波形基本相同。在较长的间隙中，正极放电比负极放电更强、更快。当林隙长度大于某一临界值时，形成时间滞后与林隙间距呈线性关系，表明该区域的传播速度恒定。据推算，50千伏的正电压点的速度为1.7千米/秒，60千伏的负电压点的速度为0.38千米/秒。这些值与液体电介质的值一致

Electro-optical measurement of prebreakdown current and breakdown time lag in polyethylene using nano-second rectangular pulse voltage

Electrical breakdown phenomena in polyethylene for the point-to-plane gap configuration were investigated using a photooptical current measuring technique and a 760-ns rectangular high-voltage pulse. The waveform of the prebreakdown current in polyethylene was essentially the same as those in liquid dielectrics. Discharge from the positive point was more intense and faster than that from the negative point in longer gap spacing. A linear relationship to formative time lag and gap spacing was observed for gap length greater than some critical value, which indicates a constant propagation velocity in this region. The velocities are deduced to be 1.7 km/s for a point positive 50-kV and 0.38 km/s for a 60-kV negative point. These values agree with those for liquid dielectrics.<>
