DIN EN 62271-207:2013-02

This part of IEC 62271 applies to gas-insulated switchgear assemblies for alternating current of rated voltages above 52 kV for indoor and outdoor installations, including their supporting structure. For switchgear devices, for example, live tank circuit breakers, IEC/TR 62271-300 is applicable. Guidance on interactions between the supporting structure and the soil/foundations is provided in Annex B. The seismic qualification of the switchgear assemblies takes into account testing of typical switchgear assemblies combined with methods of analysis. Interaction between directly mounted auxiliary and control equipment and switchgear assemblies is covered. The seismic qualification of switchgear assemblies is only performed upon request. The following changes have been made with respect to DIN EN 62271-207 (VDE 0671-207):2008-07: a) modification of the minimum voltage rating from 72,5 kV to above 52 kV; b) harmonisation of qualification procedures for GIS with IEEE 693:2005, Annexes A and P, by modifying the response spectra; c) modification of the test procedures; d) addition of criteria of allowed stresses; e) addition of dynamic analysis CQC (Complete-Quadratic-Combination method). The responsible committee is Subcommittee DKE/UK 432.2 "Typgeprüfte Hochspannungs-Schaltanlagen" ("Type-tested controlgear") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
