Hochspannungs-Schaltgeräte und -Schaltanlagen - Teil 4: Handhabungsmethoden im Umgang mit Schwefelhexafluorid (SF₆) und seinen Mischgasen (IEC 62271-4:2013); Deutsche Fassung EN 62271-4:2013
Overview
This part of IEC 62271 applies to the procedures for handling of SF6 during installation, commissioning, normal and abnormal operations, disposal at the end-of-life of high-voltage switchgear and controlgear. These procedures are regarded as minimum requirements to ensure the safety of personnel working with SF6 (see Annex B) and to minimize the SF6 emission to the environment. This standard generally applies also to gas mixtures containing SF6. The particularities for their handling are covered in Annex J. With respect to DIN V 62271-303 (VDE V 0671-303):2010-06 the following technical changes have been made: - The description of the potential effects on health of SF6 by-products (former Annex D of CLC/TR 62271-303:2009) has been replaced by the calculation methods for evaluating of the potential effects on health of SF6 by-products (see Annex H). - Information about cryogenic reclaim of SF6 has been added (see Annex I). - Handling procedures for the most popular SF6 mixture gases have been added (see Annex J). The responsible body is DKE/UK 432.1 "Hochspannungs-Schaltgeräte" ("High-voltage switchgear and controlgear") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
