标准范围

IEC 62626-1:20 23作为IEC 62626-1:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62626-1:20 23适用于封闭式开关-额定电压高达1 000 V AC的隔离开关，用于负载电路中的维修和维护工作或清洁工作。本文件范围内的设备是符合IEC 60947-3的开关隔离开关，具有特定的附加要求。本文件中的封闭式开关隔离开关适用于符合IEC 60947系列的隔离，并且没有配备用于远程控制或自动切换以避免意外或意外启动的装置。这些设备不用于操作切换，例如快速启动和停止、慢跑。这第二版取消并取代了2014年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)根据IEC 60947-1:20 20更新本文件。

IEC 62626-1:2023 is available as IEC 62626-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62626-1:2023 applies to enclosed switches-disconnectors with rated voltages up to 1 000 V AC for repair and maintenance work or cleaning work in load circuits. Devices within the scope of this document are switch-disconnectors in accordance with IEC 60947-3 with specific additional requirements. Enclosed switch-disconnectors in this document are suitable for isolation in accordance with the IEC 60947 series and are not equipped with means for remote control or automatic switching to avoid unexpected or accidental start. These devices are not used for operational switching, for example quick start and stop, jogging. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) update of this document based on IEC 60947-1:2020.
