铁路应用 - 机车车辆上的牵引变压器和电抗器

[中文适用范围]： IEC 60310:2026 RLV 版包含该国际标准的官方版本及其修订对照版（Redline 版）。修订对照版仅提供英文版，便于快速、便捷地对照官方标准与其上一版之间的所有变更。 本标准规定了铁路机车车辆用变压器和电感器的术语与定义、分类、使用条件、特性及试验方法。该文件适用于安装在机车车辆上的牵引变压器和辅助变压器，以及插入机车车辆牵引电路和辅助电路中的各类干式或油浸式电力电感器。此外，经采购方与制造商协商一致后，该文件也适用于交流单相或三相架空线路供电车辆的牵引变压器，以及车辆单相或多相辅助电路中安装的变压器。 本标准不适用于：机车车辆用仪器变压器；额定输出低于1 kVA的单相变压器或低于5 kVA的三相变压器；以及额定输出低于1 kvar的单相电感器或低于5 kvar的三相电感器。 本标准不涵盖为安装于变压器或电感器上而设计的附件（如分接开关、电阻器、热交换器、风扇等），此类附件应按相关规则单独进行试验。 本第五版取代并废止了2016年发布的第四版，属于技术修订版。相较于前一版本，本版主要技术变更包括：a) 新增变压器和电感器的典型电路；b) 增加冷却方法的字母符号；c) 修改介电试验表；d) 重组变压器和电感器的试验子条款；e) 将干式变压器和干式电感器的温升试验分别列为独立子条款；f) 根据IEC 61373:20更新冲击与振动试验要求。 [外文原描述]： IEC 60310:2026 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 60310:2026 specifies the terms and definitions, classification, service conditions, characteristics and test methods for transformers and inductors on board rolling stock. This document is applicable to traction and auxiliary power transformers installed on board rolling stock and to the various types of power inductors inserted in the traction and auxiliary circuits of rolling stock, of dry or liquid-immersed design. This document is also applicable to the traction transformers of three-phase AC line-side powered vehicles and to the transformers inserted in the single-phase or polyphase auxiliary circuits of vehicles, after agreement between purchaser and manufacturer. This document does not apply to instrument transformers, transformers of a rated output below 1 kVA single-phase or 5 kVA poly-phase, and inductors of a rated output below 1 kVAR single-phase or 5 kVAR poly-phase on board rolling stock. This document does not cover accessories such as tap changers, resistors, heat exchangers, fans, etc., intended for mounting on transformers or inductors, which are tested separately according to the relevant rules. This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) typical circuits for transformer and inductors are added; b) letter symbols for cooling methods are added; c) dielectric test table is modified; d) subclauses for the tests of transformers and inductors are restructured; e) temperature test for dry type transformer and dry type inductors are separated in different subclauses; f) requirements for shock and vibration tests are updated according to IEC 61373:20.
