标准摘要
[中文适用范围]: 本部分IEC 60076适用于三相和单相充气式电力变压器(包括自耦变压器),但不包括某些类别的小型和特殊变压器,例如: - 额定功率小于1 kVA的单相变压器和小于5 kVA的三相变压器; - 没有任何绕组额定电压高于1000 V的变压器; - 仪表变压器; - 安装在滚动设备上的牵引变压器; - 起动变压器; - 试验变压器; - 焊接变压器。 如果针对此类变压器(特别是额定电压不超过1000 V的工业应用变压器)尚不存在IEC标准,本部分IEC 60076仍可整体或部分适用。本标准未涉及使变压器适合安装在公众可进入位置的要求。对于有自己的IEC标准的电力变压器和电抗器类别,仅在另一标准中明确引用的范围内适用本部分。此类标准包括: - 一般电抗器(IEC 60076-6); - 自保护变压器(IEC 60076-13); - 风力涡轮机应用变压器(IEC 60076-16); - 牵引变压器和牵引电抗器(IEC 60310); - 工业应用变流器变压器(IEC 61378-1); - 高压直流应用变流器变压器(IEC 61378-2)。 在本部分多处规定或建议就替代或额外的技术解决方案或程序达成协议。此类协议由制造商和买方达成。此类事项应尽早提出,并将协议包含在合同规范中。 注:本标准适用于使用绝缘气体与绝缘液体混合的变压器的充气部分。 [外文原描述]: IEC 60076-15:2015 applies to three-phase and single-phase gas-filled power transformers (including auto-transformers) with the exception of certain categories of small and special transformers such as: - single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA; - transformers, which have no windings with rated voltage higher than 1 000 V; - instrument transformers; - traction transformers mounted on rolling stock; - starting transformers; - testing transformers; - welding transformers. This second edition of IEC 60076-15 cancels and replaces the first edition published in 2008 and constitutes a technical revision. The following main technical changes from the first edition are: - Modified in accordance with the related revised standards of IEC 60076-1, IEC 60076-2, IEC 60076-3 and related items of SF6 gas in the revised standard of "High-voltage switchgear and controlgear; - Added the clause "minimum power under alternative cooling modes"; - Added the clause "safety, environmental and other requirements"; - Added the clause "d.c. currents in neutral circuits"; - Added the clause "electromagnetic compatibility (EMC)"; - Added the clause "high frequency switching transients".
