低压开关设备和控制设备配件.第6部分:中继系统(母线槽)

[中文适用范围]： 本部分国际电工标准规定了低压预制母线系统（BTS）的定义、使用条件、结构要求、技术特性和验证要求，具体如下： • 额定电压不超过交流 1000 V 或直流 1500 V 的 BTS； • 用于发电、输电、配电和转换电能以及控制电能消耗设备的 BTS； • 设计用于特殊使用条件的 BTS，例如船舶、铁路车辆以及家庭应用（由非熟练人员操作），前提是符合相关的特定要求； • 设计用于机器电气设备的 BTS。构成机器一部分的 BTS 的补充要求由 IEC 60204 系列覆盖。 本标准适用于所有 BTS，无论其是单件设计、制造和验证，还是完全标准化并批量生产。 制造和/或组装可由非原始制造商进行。 本标准不适用于单独的设备或自包含的组件，如电机启动器、熔断器开关、电子设备等，这些设备应符合相关产品标准。 本标准不适用于 IEC 61439 系列其他部分涵盖的特定类型组装、符合 IEC 60570 的供电轨道系统、符合 IEC 61084 系列的电缆槽和导管系统，以及符合 IEC 61534 系列的功率轨道系统。 [外文原描述]： IEC 61439-6:2012 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low voltage BTS (see 3.101) as follows: - BTS for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; - BTS intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment; - BTS designed for use under special service conditions, for example in ships, in rail vehicles, and for domestic applications (operated by unskilled persons), provided that the relevant specific requirements are complied with; - BTS designed for electrical equipment of machines. Supplementary requirements for BTS forming part of a machine are covered by the IEC 60204 series. This first edition of IEC 61439-6 cancels and replaces the third edition of IEC 60439-2 (2000) and its Amendment 1 (2005), and constitutes a technical revision. This edition of IEC 61439-6 includes the following significant technical changes with respect to the latest edition of IEC 60439-2: - alignment on the second edition of IEC 61439-1 (2011) regarding the structure and technical content, as applicable; - introduction of new verifications, accordingly; - correction of inconsistencies in resistance, reactance and impedance measurements and calculations; - numerous editorial improvements. This publication is to be read in conjunction with IEC 61439-1:2011 .
