摘要
通过对国际标准IEC61643和国家标准GB50057-94《建筑物防雷设计规范》(2000年版)的研究,探讨了电涌保护器(SPD)在智能建筑安全设计中要考虑的若干问题。并通过工程实例,分析电涌保护器若干技术参数与设计选用要点,给出SPD的残压与冲击电流峰值的关系及各级电涌保护器具体选用时电压之间的配合关系。
Based on the research on the international standard IEC 61643 and national standard GB 50057-94 ＂design code for protection of structure against lightning＂ （ version 2000）, some problems about surge protective device （SPD） in intelligent architecture safe design were discussed. By analyzing an engineering example, several technical parameters and key points of selection for surge protective device, the relation between the residual voltage and the peak of impactive current indifferent waves, the voltage＇ s coordination relation in selection of various SPD were given out.
