标准摘要
[中文适用范围]: 本国际标准适用于以下具有两个或多个极点的轨道系统,用于将灯具连接到电源,包括: - 极点间额定电压不超过440V(带电导体)并提供接地(I类)的系统,每导体额定电流不超过16A,或 - SELV系统,额定电压不超过25V交流或60V直流,不提供接地(III类),每导体额定电流不超过25A,或 - 上述两种系统的组合(混合供电系统),用于同时连接主电压灯具(I类或II类)和SELV供电灯具(III类),但在不同的区域(主电源或SELV)。 轨道系统还可以提供灯具的机械支撑。 它适用于设计用于普通室内用途的轨道系统,安装在墙壁和天花板上或嵌入或悬挂。这些轨道系统不适用于特殊条件如船舶、车辆等以及危险场所,例如可能发生爆炸的地方。 [外文原描述]: IEC 60570:2003+A1:2017 applies to track systems for ordinary interior use with two or more poles and with provision for earthing (Class 1), with a rated voltage not exceeding 440 V between poles (live conductors), rated frequency not exceeding 60 Hz and a rated current not exceeding 16 A per conductor for the connection of luminaires to the electrical supply. This consolidated version consists of the fourth edition (2003) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
