电源电涌保护器与被保护设备之间连接导线长度的计算

Length Calculation of Connection Wire Between Power Surge Protective Device and Protected Equipment

根据防雷规范的计算方法和实际条件,计算了末级电源线路电涌保护器(SPD)与被保护设备之间的连接导线避免振荡保护距离和感应保护距离长度。计算结果表明,设计时末级电源SPD与被保护设备之间的避免感应保护距离和避免振荡保护距离应为6.36 m。

Based on the calculation methods of lightning protection and actual condition, the connection wire length between power surge protective device（ SPD） and protected quipment was calculated. The calculation results show that the avoiding oscillation protection length and sensing protection length is 6.36 m between last stage power SPD and protected equipment.
