Dianci bileiqi, 2018 利用气体放电管、ZnO压敏电阻与TVS管配合退耦原件构成的多级SPD,通过1.2/50μs、8/20μs组合波对其进行限制电压和组合波冲击试验。研究表明:在1.2/50μs开路电压波冲击下,线-地之间限制电压保持在450 V左右,线-线之间的限制电压可以维持在40 V左右;在组合波冲击实验下,线-地模式和线-线模式下,实际冲击试验中的残压总体相差不大,都是随着冲击电压的升高呈上升趋势,两种模式下的通流容量尽管都随着冲击电压的升高呈上升趋势,但在同等冲击电压下,通流容量差异却很大。

Dianci bileiqi冲击电流试验是高压试验的重要组成部分，广泛应用于避雷器和电涌保护器等产品的试验检测。当试品为线性负载时，某一冲击电流幅值对应的试验设备充电电压可通过理论公式进行相对精确的计算；当试品为避雷器等非线性负载时，与之对应的设备充电电压则难以确定。通常需要基于大量历史数据和长期经验累积、或反复调试方能确定合适的充电电压。为此，基于理论推导，提出了适用于避雷器/电阻片等非线性负载情况下，估算冲击电流幅值所对应试验设备充电电压的方法，并采用多种电阻片进行了验证，试验结果表明该估算方法较为准确 ...
