23、ATIONS FIXED INSTALLATIONS PARTICULAR REQUIREMENTS FOR AC SWITCHGEAR Part 3-3: Measurement, control and protection devices for specific use in a.c. traction systems Single-phase inductive voltage transformers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization

24、 for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC pub

25、lishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may

26、 participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreeme

27、nt between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Pub

28、lications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or

29、 for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corres

30、ponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the la

31、test edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, wh

32、ether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

33、indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 6

39、tive voltage transformers used at traction voltages and frequencies according to IEC 60850. The requirements contained in this Standard complement those given in IEC 60044-2:1997. 6 62505-3-3 IEC:2009 RAILWAY APPLICATIONS FIXED INSTALLATIONS PARTICULAR REQUIREMENTS FOR AC SWITCHGEAR Part 3-3: Measur

40、ement, control and protection devices for specific use in a.c. traction systems Single-phase inductive voltage transformers 1 Scope This part of IEC 62505 gives particular requirements for voltage transformers used in a.c. single-phase railway applications, fixed installations. This International St

41、andard applies to inductive voltage transformers used at traction voltages and frequencies according to IEC 60850. The main uses of these voltage transformers are: voltage indication; measurement; protection. 2 Normative references The following referenced documents are indispensable for the applica

42、tion of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
