标准摘要
[中文适用范围]： 本部分IEC 62271适用于室内或室外安装的直流断路器（以下简称DC断路器），其直流电压为100 kV及以上，用于直流输电和配电系统。 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、功率电子开关、一次辅助电路和能量耗散系统，以及它们的控制。根据设计和系统需求，操作可以是单向电流（单向）或双向电流（双向）。 本文件不包括： IEC TS 63014-1中描述的用于降低故障电流上升率的串联电抗器。虽然这些通常与直流断路器的操作一起安装，但它们通常是系统特定的。 [外文原描述]： 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).
