摘要
低压配电系统中,常采用多级SPD释放电涌能量,以保护用电设备因雷电过电压、操作过电压及暂态过电压而绝缘损坏。本文基于行波理论分析各级SPD的关系,对各种能量配合方案进行分析,对工程实际具有重要指导意义。
In low-voltage power distribution system, often adopts multi-stage SPD release surge energy, to protect the Insulation of equipment damage from lightning, switching over-voltage and temporary over-voltage. Based on traveling wave theory, the paper analyzes the relationship between multi-stage SPD, and the analysis of various kinds of energy cooperation schemes, which has important guiding significance for engineering practice.
