GB/T 12667-2012General specification for excitation assembly with semiconductors for synchronous motors (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft. This standard replaces GB/T 12667-1990 "synchronous motor excitation semiconductor devices General technical conditions." This standard and GB/T 12667-1990 compared to the main technical changes are as follows:

--- Modify the content of the AC grid quality (see 426, 1990 Edition 3.2.6.);

--- Modify the interference content (see 4413, 1990 version 3.12.);

--- Increase the functional requirements (see 4.6);

--- Remove the transit test (1990 Version 4.15);

--- Custody and removed the contents of the product quality (1990 Version 6.5). The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee on Electronic electrodynamic (SAC/TC60) centralized. This standard drafting units. Tianjin Electric Drive Design Institute, Beijing Hiconics Inverter Technology Co., Ltd., Tianjin red Japan Electric Automation Co., Ltd., Shenzhen INVT Electric Co., Ltd., on Haileinuoer Technology Co., Ltd., Shanghai and Australia-Wei Fall Power Electronic Co., Ltd. The main drafters of this standard. Anping, Duxin Lin, Fu Wenjie, Dongrui Yong, Chen Guoqiang, Liu Zhi. This standard replaces the standards previously issued as follows:

1 Scope

GB/T 12667-2012 is the Chinese national standard on general specification for excitation assembly with semiconductors for synchronous motors, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 June 2012 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2012. Classification: ICS 29.160.30, CCS K62. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions of the semiconductor synchronous motor excitation device, technical requirements, testing, marking, packaging, transportation and storage. This standard applies to the installation of indoor light or heavy start, or full voltage starting voltage drop of the semiconductor synchronous motor excitation device (to Hereinafter referred to as the device).
