标准摘要
[中文适用范围]： IEC TS 62271-313:2025 EXV 包含国际标准及其扩展版本 (EXV)。此官方 IEC 标准的扩展版本仅提供英文版，为用户提供标准的全面内容。IEC TS 62271-313:2025 EXV 包括对 IEC TS 62271-5:2024 的引用内容。IEC TS 62271-313:2025 适用于直流电压为 100 kV 及以上的室内或室外安装直流断路器（以下称为直流断路器），用于直流输配电系统。本文件包括（机械）开关设备，包括剩余电流中断设备及其操作设备、电力电子开关、一次辅助电路和能量耗散系统，以及它们的控制装置。根据设计和系统需要，操作可以仅针对一个电流方向（单向）或针对两个方向（双向）。 [外文原描述]： IEC TS 62271-313:2025 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC TS 62271-313:2025 EXV includes the content of the references made to IEC TS 62271-5:2024. IEC TS 62271-313:2025 is applicable to direct current circuit-breakers (hereafter termed DC circuit-breakers) for indoor or outdoor installation having direct voltages of 100 kV and above for operation on DC transmission and distribution systems. This document includes the (mechanical) switching devices, including the residual current interruption devices, and their operating devices, power electronic switches, primary auxiliary circuits and energy dissipation systems, as well as their controls. Depending on design and system needs, operation can be for one current direction only (unidirectional) or for both directions (bidirectional).
