标准摘要
[中文适用范围]: IEC 61534的本部分规定了额定电压不超过277 V交流单相或480 V交流两相或三相50 Hz/60 Hz、额定电流不超过63 A的动力跟踪(PT)系统的一般要求和测试。这些系统用于家庭、商业和工业场所的电力分配。符合本标准的 Powertrack 系统@旨在在以下条件下使用: 环境温度在 ℃5 至 + 40 ℃范围内24 小时内的平均值不超过 35 ?? ?C 不受可能使温度超过上述限制的热源影响的情况; ?C 海拔不超过2000米; ?C 不受烟雾@化学烟雾@长时间高湿度或其他异常条件过度污染的大气。在存在特殊条件的场所@如船舶@车辆等以及危险场所@例如@容易发生爆炸的场所@可能需要特殊结构。本标准不适用于IEC 61084[8]1涵盖的C电缆槽道系统和电缆管道系统; ?IEC 60439-2 [5] 涵盖的 C 母线槽系统; IEC 60570 [6] 涵盖的灯具的 ?C 供电轨道系统。 [外文原描述]: IEC 61534-1:2011 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.
