15、llowing significant technical changes with respect to EN 62271-107:2005: the reference to EN 60694 has been changed to EN 62271-1; the new clauses and subclauses from EN 62271-1 have been added and where necessary new wording has been provided: 4.11 Rated filling levels for insulation and/or operati

16、on; 5.19 X-ray emission; 5.20 Corrosion; 6.10 Additional tests on auxiliary and control circuits; 6.11 X-radiation test procedure for vacuum interrupters; 12 Influence of the product on the environment; the normative references have been updated: EN 60265-1 to EN 62271-103, IEC 60787 to IEC/TR 60787

17、, IEC 60466 to EN 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 in

18、cluded in EN 62271-1; the acceptance criteria have been aligned with 6.101.4 of EN 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

19、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 EN 62271-1.

20、rd is to be read in conjunction with EN 62271-1:2008, to which it refers and which is applicable unless otherwise specified. In order to simplify the indication of corresponding requirements, the same numbering of clauses and subclauses is used as in EN 62271-1. Amendments to these clauses and subcl

21、auses are given under the same numbering, whilst additional subclauses, are numbered from 101.

48、s replaced as follows. This part of IEC 62271 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 in

49、cluding the rated short-circuit breaking current; making, at the rated voltage, circuits to which the rated short-circuit breaking current applies. They are intended to be used for circuits or applications requiring only a normal mechanical and electrical endurance capability. Such applications cover protection of HV/LV transformers for instance, but exclude distribution lines or cables, as well as motor circuits and capacitor bank circuits.
