标准摘要
[中文适用范围]: 本部分IEC 62626适用于额定电压高达1000 V交流的封闭式开关-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源自符合IEC 60947-3的开关-隔离开关,并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,并且不配备远程控制或自动切换装置,以避免意外或偶然启动。这些设备不用于操作切换,例如快速启动和停止或点动。 注1:然而,这种设备可以提供关闭电气设备的可能性(即使在危急情况下或非危急情况下)。 本文件范围内的设备在维修和维护或清洁工作期间提供电气设备的隔离,特别是在电机电路中。 用于各种应用的封闭式开关-隔离开关,在维修和维护工作期间提供电气设备的隔离,称为“维护开关”,以下称为具有以下特性的设备: a) 不同类别; b) 每个类别的特性; c) 最低测试要求; d) 设备上标记的信息或制造商提供的信息,例如在目录中。 注2:本文件未指定这些开关应用所需的附加要求,例如在爆炸性环境中(例如欧洲的ATEX)。 [外文原描述]: IEC 62626-1:2023 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 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.
