阀门装置栈和组件,以及功率转换设备的端子标记

[中文适用范围]： 本国际标准适用于阀装置组和组件以及集成转换设备主电路的端子标记。端子标记指的是包含半导体阀装置的堆栈@组件和设备。注 1：本标准不考虑辅助电路@的端子标记，包括门端子和其组件单独制造且仅在现场安装后才互连的非集成转换设备。对于此类设备，各个组件的相关标准@（如果有）适用。门端子标记见 6.3。本标准不考虑其他电路的端子标记，例如保护导体。本标准的目的是规定一种逻辑字母数字标记系统，用于识别堆栈@阀门装置组件或集成转换设备@中主电源电路的外部主端子，适用于电路图@中的参考目的。目录@描述@以及信息交换和存储。在堆栈和组件的情况下，@字母数字端子标记系统表示那些最重要和最常用的转换器连接。本标准不考虑使用图形符号或识别颜色的端子标记系统。注 2：辅助电路的端子应进行标记，以便可以清楚地识别。 [外文原描述]： IEC 61148:2011 is applicable to the terminal markings for the main circuits of valve device stacks and assemblies, and of integrated conversion equipment. The terminal markings refer to stacks, assemblies and equipment comprising semiconductor valve devices. The object of this standard is to specify a logical alphanumeric marking system for the identification of the external main terminals of the main power circuits in a stack, valve device assembly or integrated conversion equipment, which is applicable for the purpose of reference in circuit diagrams, catalogues, descriptions, and information exchange and storage. In the case of stacks and assemblies, alphanumeric terminal marking systems are indicated for those converter connections which are the most important and most commonly used ones. Terminal marking systems making use of graphic symbols or identifying colours are not considered in this standard. This second edition includes the following significant technical changes with respect to the previous edition: - the whole document has been rewritten according to the current Directives; - the identification codes were deleted according to the withdrawal of IEC 60971; - examples of terminal marking were added, especially for self-commutated converters.
