GB/T 13540-2009Seismic qualification for high voltage switchgear and controlgear (English PDF)

Foreword

This revised standard adopts IEC 62271-2:2003 "high-voltage switchgear and control equipment Part 2. Rated voltage 72.5kV and to Seismic requirements on ", while referring to the IEC 62271-207:2007" high-voltage switchgear and control equipment Part 207. Rated voltage Seismic requirements than 52kV gas insulated switchgear equipment "and IEC 62271-300:2006" high-voltage switchgear and control provided Test methods are cited GB/T 2423.43, GB/T 2423.48 and GB/T 2424.25 the three standards, this standard does not make Repeat;

--- This standard is mainly used original product "fortification intensity of 8 degrees to 9 degrees strut porcelain high-voltage switchgear" extended to "the amount of Constant voltage 3.6kV and above all high-voltage switchgear and control equipment "(such as. high-voltage AC circuit breakers, high voltage AC isolation and earthing switches, 72.5kV and above gas-insulated metal-enclosed switchgear (GIS), 3.6kV ~ 40.5kV AC Metal-enclosed switchgear, HV/LV prefabricated substations, etc.);

--- Applicable seismic ground level from the original horizontal acceleration 3m/s2 (corresponding to the reference seismic intensity VIII ~ IX degree degrees) outward expansion Exhibition to 2m/s2,3m/s2,5m/s2 (corresponding to the reference seismic intensity were. IX degree of = range;

--- Standards adopted in response spectrum damping ratios of 2%, 5%, 10%, 20% and greater, and the original standard of 3%, 5%, 7%, 10%, 15%.

Appendix A of this standard is a normative appendix, Appendix B, Appendix C are informative appendices.

The standard proposed by China Electrical Equipment Industrial Association.

This standard by the national high-voltage switch equipment Standardization Technical Committee (SAC/TC65) centralized.
