低压配电系统中SPD应用研究

Research on SPD application in low voltage distribution system

首先简要分析低压配电系统中装设SPD的必要性,并在阐述防雷分区划分的基础上,明确了不同级分类试验SPD的制造依据,进而着重就工程设计中的SPD应用中SPD的选择进行详尽的分析,并对采用断路器及熔丝做后备保护做了简单分析比较。

The paper has the brief introduction of the necessity for the installation of SPD in low voltage distribution system, ensures the manufacturing basis for SPD in various classified experiments, emphasizes on the selection of SPD in the application of SPD in project design, and has the analysis and comparison of the backup protection for the circuit breaker and the fuse.
