低压配电系统电源过电压保护器能量配合分析

Discussion about the Surge Protective Devices Cooperation in the Low-Voltage Distribution System

利用行波理论分析了各级SPD线路长度距离,并提出SPD接地线长度与SPD能量配合的密切关系。

In the multi-level Surge Protective Devices equipment forlightning protection, the SPDs only by meet （SPD） on the electronic systems and ing certain conditions to ensure the SPDs level by level working when the lightning starts The tex using light waves theoretical analysis of the SPD settings, put SPD grounding line with the length of the relationship between the SPD with energy.
