18、ing clients of the SABS. 4 62271-205 IEC:2008 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR Part 205: Compact switchgear assemblies for rated voltages above 52 kV FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for sta
19、ndardization 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 publishes I
20、nternational 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 partici
21、pate 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 agreement betw
22、een 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 Publicatio
23、ns 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 for an
24、y 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 corresponding
25、 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 latest ed
26、ition 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, whether d
27、irect 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 indispe
28、nsable 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 62271-20
29、5 has been prepared by subcommittee 17C: High-voltage switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and controlgear. This standard should be read in conjunction with IEC 62271-1, first edition, to which it refers and which is applicable, unless otherwise specified.
30、 In order to simplify the indication of corresponding requirements, the same numbering of clauses and subclauses is used as in IEC 62771-1. Amendments to these clauses and subclauses are given under the same numbering, whilst additional subclauses are numbered from 101. SANS 62271-205:2008This stand

A list of all the parts in the IEC 62271 series, under the general title High-voltage switchgear and controlgear, can be found on the IEC website. The committ
33、ee 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 revise

35、his part of IEC 62271 applies to compact switchgear assemblies consisting of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction between the functions of the individual devices. Such assemblies are made up of de
36、vices defined in 1.101 and are designed, tested and supplied for use as a single unit. The interaction between devices may be due to proximity, sharing of components or a combination of both. The assemblies may contain components of air insulated switchgear (AIS) only or a combination of AIS and gas
37、 insulated switchgear (GIS), so called mixed technology switchgear (MTS) and may be delivered entirely prefabricated or partially assembled. It is not possible to define all potential arrangements of compact switchgear assemblies however four examples are shown for information in Annex A. These comp
38、act switchgear assemblies are for indoor and/or outdoor installations in systems having rated voltages above 52 kV and service frequencies of 50 Hz and 60 Hz. This standard covers the influence on performance of the interactions between devices within compact switchgear assemblies and defines rating
39、s and test procedures for these assemblies. IEC 62271-1 is applicable if not stated otherwise. This standard does not apply to switchgear assemblies consisting solely of GIS which are covered by 62271-203. 1.101 Objective The objective of this standard is to respond to the increasing use of compact
40、switchgear assemblies that perform the functions of a number of separate devices and their controlgear. Numerous arrangements are possible and this standard provides guidance on basic types of assemblies which might be envisaged. As there are potential interactions between devices within such assemb
41、lies, it is necessary to consider the standardization requirements for the assembly in its entirety. The devices, defined by IEC standards, which may form part of a compact switchgear assembly are listed below: SANS 62271-205:2008This standard may only be used and printed by approved subscription an
