标准摘要
[中文适用范围]： 1.1 本部分 IEC 61534 规定了额定电压不超过277V交流单相或480V交流两相或三相50Hz或60Hz，额定电流不超过63A的电力导轨(PT)系统的通用要求和测试。这些系统用于住宅、商业和工业场所的电力分配。 1.2 根据本标准，电力导轨系统适用于以下条件：-5°C至+40°C的环境温度范围，24小时期间的平均值不超过35°C；不受可能使温度超过上述限制的热源影响；海拔不超过2000米；不受烟雾、化学烟雾、长期高湿度或其他异常条件的过度污染。在特殊条件下，如船舶、车辆等场所和危险场所（例如可能发生爆炸的地方），可能需要特殊结构。 本标准不适用于：IEC 61084 1涵盖的电缆槽系统和电缆管道系统；IEC 60439-2涵盖的母线槽系统；IEC 60570涵盖的灯具供电轨道系统。 [外文原描述]： IEC 61534-1:2011+A1:2014 specifies general requirements and tests for powertrack (PT) systems with a rated voltage not exceeding 277 V a.c. single phase, or 480 V a.c. two or three phase 50 Hz/60 Hz with a rated current not exceeding 63 A. These systems are used for distributing electricity in household, commercial and industrial premises. This second edition cancels and replaces the first edition published in 2003 and constitutes a technical revision. The main changes from the previous edition are as follows: - updated normative references (Clause 2); - changes to the number of samples to be tested (Subclause 5.3); - inclusion of a short circuit test (New Clause 18); - changes to external influences (Clause 21). The contents of the corrigendum apply to the French version only. This consolidated version consists of the second edition (2011) and its amendment 1 (2014). Therefore, no need to order amendment in addition to this publication.
