架空线路结构.荷载试验

[中文适用范围]： 本文件规定了架空线路支撑物的测试方法和程序。 它适用于电压超过45kV的架空线路支撑物和结构的测试；也可作为低压支撑物测试的参考。 对支撑物制造所用材料类型没有限制，包括但不限于金属合金、混凝土、木材、层压木材和复合材料。如果客户要求，本文件也可应用于电信支撑物、铁路/电车架空电气化支撑物、变电站门架、路灯柱、风力涡轮机塔、滑雪缆车支撑物等的测试。 本文件不包括支撑物缩小模型的测试。 [外文原描述]： IEC 60652:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
