有关在电信终端设备中使用电涌保护设施和电涌保护组件的安全指导 |
[IEC 62368-1]第5.5.7节描述了设备中电涌保护装置(SPD)在一次电路和保护接地之间桥接的要求。然而,[IEC 62368-1]没有考虑雷电电压,雷电电压大于过电压二类条件下出现的雷电电压,也没有提供无接地二类设备雷电保护的必要要求,在无接地二类设备中,通常采用SPD/电涌保护器(SPC)进行桥接。为了实现通信系统的电阻性和安全性,有必要明确SPD/电涌保护器(SPC)的电气要求。ITU-T K.143建议书分析了电涌保护器跨越绝缘的雷电措施对人类安全的影响。ITU-T K.143建议书从人类安全的角度为防雷设计和电涌保护器的要求提供了指导。设备外部的多用途电涌保护装置(MSPD)和安装在建筑物线路上的SPD对SPD/SPC的要求不在本建议的范围内。 |
