标准摘要
[中文适用范围]： 本部分IEC 62626适用于额定电压不超过1000V交流电的封闭式开关-隔离开关，用于负载电路的维修、维护或清洁工作。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-隔离开关适用于根据IEC 60947系列进行隔离，并且不配备远程控制或自动开关装置，以避免意外或意外启动。这些设备不用于操作开关，例如快速启动和停止、点动。 [外文原描述]： 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.
