标准摘要
[中文适用范围]： IEC 62626-1 的这部分的适用范围为额定电压高达 1000 V 交流电的封闭式开关隔离器，用于负载电路的维修、维护或清洁工作。标准范围内的设备源自符合 IEC 60947-3 的开关隔离器。本标准中的封闭式开关隔离器适用于符合 IEC 60947 系列的隔离，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。这些设备不应用于操作切换、快速启停或点动。这些设备为电气设备的隔离提供可能，特别是在电机电路中，用于维修、维护或清洁工作期间。 适用于各种应用的封闭式开关隔离器，用于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”。 [外文原描述]： IEC 62626-1:2014 applies to enclosed switches-disconnectors with rated voltages up to 1 000 V a.c. for repair and maintenance work or cleaning work in load circuits. Devices within the scope of this standard are derived from switch-disconnectors according to IEC 60947-3. Enclosed switch-disconnectors in this standard are suitable for isolation according to IEC 60947 series and are not supposed to be equipped with means for remote control or automatic switching to avoid unexpected or accidental start. These devices are not intended to be used for operational switching, quick start and stop or jogging.
