Title High-voltage switchgear and controlgear - Part 107: Alternating current fused circuit-switchers for rated voltages above 1 kV up to and including 52 kV
Project Number 23368
Abstract/Scope IEC 62271-107:2012 applies to three-pole operated units for distribution systems that are functional assemblies of a circuit-switcher and current-limiting fuses designed so as to be capable of: - breaking, at the rated recovery voltage, any load or fault current up to and including the rated short-circuit breaking current; - making, at the rated voltage, circuits to which the rated short-circuit breaking current applies. This second edition cancels and replaces the first edition, published in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. - the reference to IEC 60694 has been changed to IEC 62271-1; - the new clauses and subclauses from IEC 62271-1 have been added and where necessary new wording has been provided; - the normative references have been updated: IEC 60265-1 to IEC 62271-103, IEC 60787 to IEC/TR 60787, IEC 60466 to IEC 62271-201, and IEC/TR 60787 was moved to the bibliography; - the figures and tables have been placed in the document where they are first cited; - the numbering of figures and tables has been changed to obtain the correct order; - the definition of NSDD was deleted. This definition is included in IEC 62271-1; - the acceptance criteria have been aligned with 6.101.4 of IEC 62271-103:2011; - the various provisions expressed about 'extension of the validity of type tests' have been grouped under 6.103: some of the rules were duplicated in Clauses 6 and 8, and it seems better fitted to deal within each type test sub-clause only with the type test to be performed. Conditions have not been changed, but the wording is clearer; - new numbering of subclauses in Clauses 8 and 9 to avoid conflict with clauses from IEC 62271-1.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
