26、fic requirements for synchronous generators driven by steam turbines or combustion gas turbines FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of
27、 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 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (P
28、AS) 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 participate in this preparatory work. International, governmental and non-governmental organizations liaising wi
29、th the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as n
30、early 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 Publications have the form of recommendations for international use and are accepted by IEC National Committees in t
31、hat 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 for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committ
32、ees 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 corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking pro
33、cedure 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 latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or ag
34、ents 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, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of
35、, 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 indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some
36、 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 60034-3 has been prepared by IEC Technical Committee 2: Rotating machinery. This sixth edition cancels and replace
37、s the fifth edition published in 2005. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: the contents is now restricted to synchronous generators driven by steam turbines or combustion gas turbines, but covers as wel
38、l cylindrical rotor and salient-pole generators; synchronous motors have been taken out of the scope of part 3. 60034-3 IEC:2007 5 The text of this standard is based on the following documents: FDIS Report on voting 2/1461/FDIS 2/1474/RVD Full information on the voting for the approval of this stand
39、ard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60034 series, published under the general title Rotating electrical machines, can be found on the IEC website. The co
40、mmittee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a r
41、evised edition, or amended. 6 60034-3 IEC:2007 ROTATING ELECTRICAL MACHINES Part 3: Specific requirements for synchronous generators driven by steam turbines or combustion gas turbines 1 Scope This part of IEC 60034 applies to three-phase synchronous generators, having rated outputs of 10 MVA and ab
42、ove driven by steam turbines or combustion gas turbines. It supplements the basic requirements for rotating machines given in IEC 60034-1. Common requirements are prescribed together with specific requirements for air, for hydrogen or for liquid cooled synchronous generators. This part of IEC 60034
43、also gives the precautions to be taken when using hydrogen cooled generators including: rotating exciters driven by synchronous generators; auxiliary equipment needed for operating the generators; parts of the building where hydrogen might accumulate. NOTE 1 These requirements also apply to a synchr
44、onous generator driven by both a steam turbine and a combustion gas turbine as part of a single shaft combined cycle unit. NOTE 2 These requirements do not apply to synchronous generators driven by water (hydraulic) turbine or wind turbine. NOTE 3 The precautions to be taken when using hydrogen are
45、valid for all cases where hydrogen is used as a coolant. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (incl
46、uding any amendments) applies.
