15、HNICAL COMMISSION _ ELECTRICAL HIGH-VOLTAGE EQUIPMENT IN HIGH-VOLTAGE SUBSTATIONS COMMON RECOMMENDATIONS FOR PRODUCT STANDARDS FOREWORD This second edition of IEC Guide 111 has been prepared in accordance with Annex A of Part 1 of the ISO/IEC Directives by an ad hoc group of the Standardization Mana
16、gement Board set up to harmonize characteristics for substation standards. It constitutes a technical revision of the first edition, published in 1998. This edition has been amended to express more clearly the guidance being provided to product committees and contains corrected and completed technic
17、al material and references. The text of this guide is based on the following documents: Approval document Report on voting C/1325/DV C/1334/RV Full information on the voting for the approval of this Guide can be found in the report on voting indicated in the above table.

19、mittees (TCs) involved in high-voltage (HV) substation systems, such as: TC 13, TC 14, TC 17, TC 20, TC 22, TC 28, TC 32, TC 33, TC 36, TC 37, TC 38, TC 57, TC 95, TC 99. It is of paramount importance that the IEC, through this Guide, finds a way to overcome the lack of consistency and unnecessary d
20、iscrepancies between standards within one system, even though a few discrepancies might be justified in certain cases according to the specificity of a given product or situation. Furthermore, the cost of over-standardization of one component when the nearest linked component is under-standardized s
21、hould be considered. The supplementary cost does not in any way increase the reliability of the system as a whole. Since the same external stresses (climatic, electrical, mechanical) apply to all the components of the substations, the consistency of their technical features is vital. Hence, standard
22、s will deal more and more with the same essential requirements for safety, environmental impact, end of life, availability and integration of systems. All product standards for a single system have to fulfil these requirements with the same degree of responsibility. The aim of this Guide is to provi
23、de common rules for HV substation equipment.

24、Guide 111 IEC:2004(E) ELECTRICAL HIGH-VOLTAGE EQUIPMENT IN HIGH-VOLTAGE SUBSTATIONS COMMON RECOMMENDATIONS FOR PRODUCT STANDARDS 1 Scope IEC Guide 111 is a horizontal publication which gives guidance for the harmonization of product and system standards within substations where the highest voltage f
25、or equipment is higher than 1 kV. It primarily addresses conventional a.c. equipment which is found in high- voltage (HV) substations in most cases. This Guide contains recommendations for common specifications for all HV substation product standards, each of which is augmented by the technical back
26、ground specific to each TC, which naturally retains freedom in its technical choices. Where HV power electronic equipment is part of an HV substation, for example, HVDC or SVC, economics and technology dictate a deviation from common clauses as standardized for a.c. equipment. However, when developi
27、ng product standards for HV power electronic equipment for use in HV substations, the common recommendations of this Guide should be adopted as far as possible. Clearly, any specification in this guide which is inapplicable to a certain type of product, because of that products inherent characterist
28、ics, for example, should not be taken into account when writing standards for that type of product. 2 Reference documents IEC 60027-1, Letter symbols to be used in electrical technology Part 1: General IEC 60038, IEC standard voltages IEC 60059, IEC standard current ratings IEC 60060-1, High-voltage

41、e utmost importance for the harmonization process. Strong reasons are needed to depart from the recommendations of horizontal publications, and, in all cases, it is necessary to explain the reason for any discrepancy. Within the fields concerned, the essential horizontal documents to be taken into a
42、ccount and to be mentioned in the normative references clause of each standard are the following: field of definitions: International Electrotechnical Vocabulary (IEC 60050); field of voltage: IEC 60038; field of current: IEC 60059; field of insulation: IEC 60060, IEC 60071, IEC 60815 and IEC 61180;
43、 field of temperature rise: IEC 60216 and IEC 60943; field of degrees of protection: IEC 60529; field of environment: IEC 60664, IEC 60721, IEC 61166, IEC 60376, IEC 60296, IEC 60867 and IEC Guide 109; field of electromagnetic compatibility (EMC): IEC Guide 107; horizontal publications in the IEC 61
44、000 series; CISPR 11, 18, 22 and 24; field of safety: IEC Guide 104; ISO/IEC Guide 51; ISO 60695 series field of mechanical stresses: IEC 60865 and IEC 62155. 4 Guidance for the “Definitions” clause in product standards Definitions already in the IEV should always be used. If a definition already in
45、 the IEV is not satisfactory or not clear enough, the difficulty should be referred to TC 1 and solved in cooperation. New definitions should be discouraged unless absolutely necessary, i.e. no similar definition exists in publications on a similar subject. A similar definition may be modified with
46、a reference to the original. 5 Environmental conditions 5.1 General This clause should be the same for all TCs active in the area of substations. Installations, including all devices and auxiliary equipment which form an integral part of them, should be designed for operation under the climatic and
47、environmental conditions listed below. Equipment product standards should be taken into account. It is recommended that TCs should use the phrase “environmental conditions” in preference to “service conditions”.
