GB/T 21226-2007 in English

《GB/T 21226-2007半导体变流器 变流联结的标识代号》由TC60（全国电力电子系统和设备标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准规定的仅仅是最主要和最常用的、由阀器件构成的变流联结，并可用于作为堆和装置整个额定值代号的一部分。适用于GB/T 3859所包括的变流器设备的二极管、变流器装置的变流联结。

Scope

1.1 Scope This standard applies to the diodes and thyristor stacks of the converter equipment included in GB/T 3859, and the converter connection of the converter device. This standard specifies only the most important and most commonly used variable flow couplings composed of valve devices, and can be used as part of the overall rating designation of stacks and devices. Appropriate parts of this standard may also be used in other standards dealing with power electronic conversion of valve device stacks and devices for variable flow coupling. 1.2 Purpose The purpose of this standard is to specify a logical system using a set of alphanumeric symbols to identify the coupling of the main arm and the most important auxiliary arm (if any) of the stack of valve components and installations, including the coupling structure of all coupling structures under study. Necessary information. Therefore, this designation can replace the connection diagram and is suitable for insertion into the overall rating designation of stacks and devices, and also facilitates the dissemination, exchange, storage and reprinting of converter characteristic information. For terms and definitions used in this standard, see GB/T 2900.33 and GB/T 3859.
