轨道交通应用 机车车辆上的变压器和电感器

[中文适用范围]： IEC 60310:2026规定了轨道交通用变压器和电抗器的术语和定义、分类、使用条件、特性以及试验方法。本文件适用于安装在轨道交通车辆上的牵引变压器和辅助变压器，以及插入牵引和辅助电路的各种类型的干式或油浸式电抗器。经采购方与制造商协商后，本文件亦适用于三相交流供电车辆所使用的牵引变压器，以及插入车辆单相或多相辅助电路中的变压器。本文件不适用于轨道交通用仪用变压器、额定输出低于1 kVA的单相变压器或低于5 kVA的多相变压器，以及额定输出低于1 kVAR的单相电抗器或低于5 kVAR的多相电抗器。本文件未涵盖为安装在变压器或电抗器上的配件（如分接开关、电阻器、热交换器、风扇等），此类配件须按相关规则单独测试。第五版取代了2016年发布的第四版，构成一项技术性修订。本版与前一版相比，主要技术变更包括：a）增补了变压器和电抗器的典型电路；b）增补了冷却方式的字母符号；c）修改了介电试验表；d）对变压器和电抗器试验的子条款进行了结构调整；e）将干式变压器和干式电抗器的温度试验分设至不同子条款；f）根据IEC 61373:20更新了冲击与振动试验要求。 [外文原描述]： 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.
