GSO IEC 61854:2023 架空线路 间隔器的要求和测试

IEC 61854:2020 is available as IEC 61854:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61854:2020 applies to spacers for conductor bundles of overhead lines. It covers rigid spacers, flexible spacers and spacer dampers. It does not apply to interphase spacers, hoop spacers and bonding spacers. This document is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this document may not be applicable. In some cases, test procedures and test values are left to agreement between purchaser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties; b) Specify as far as possible test parameters and acceptance values; c) Avoid as far as possible the alternative procedures for the same test; d) Introduce a simpler test device for the simulated short circuit current test; e) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers; f) Prescribe a different procedure for subspan oscillation tests on spacers equipped with clamps having rod attachments; g) Modify the test procedure for the aeolian vibration tests; h) Prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments; i) Re-edit all the figures in order to make them more clear and homogeneous; j) Introduce an additional test device for the simulated short circuit current test.

GSO IEC 60652:2023 架空线路结构 负载测试

IEC 60652:2021 is available as IEC 60652:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60652:2021 specifies the methods and procedures of testing supports for overhead lines. It applies to the testing of supports and structures of overhead lines. There is no restriction on the type of material used in the fabrication of the supports which may include, but not be limited to, metallic alloys, concrete, timber, laminated wood and composite materials. If required by the client, this document can also be applied to the testing of telecommunication supports, railway/tramway overhead electrification supports, electrical substation gantries, street lighting columns, wind turbine towers, ski-lift supports, etc. Tests on reduced scale models of supports are not covered by this document. This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified; b) Added reference to CIGRE Brochure 399; c) In Clause 7, added test limitation for wind speed and direction during testing; d) In paragraph 10.5, added load increments for destruction tests; e) In paragraph 10.7, added a requirement for an agreement between client and testing station when testing supports made of creep-sensitive materials; f) In Clause 17, added requirements for sampling procedure to be provided in the test report.
