Hong Bin · Low Voltage Apparatus · 2006
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.
