Scope

GB/T 39226-2020 is the English-translated version of 磁约束聚变大电流变流系统集成测试要求.

GB/T 39226-2020 fixes the test items, the test conditions, the test methods and processes, and the qualification criteria for the integration of magnetic confinement fusion high current converter systems.

Clause 1 states that it applies to the integration test of such systems when they use thyristors greater than 10 kA.

The body is short: after Scope, Normative references and Terms and definitions come Requirements for integration testing and Test method and process, with an informative Appendix A holding the structure diagram of a 12-pulse, four-quadrant operation converter unit.

Clause 2 cites GB/T 2900.33-2004, GB/T 3859.1-2013, GB/T 3859.3-2013, GB/T 12325, GB/T 12326, GB/T 14549 and GB/T 15543.

Clause 3 repeats some of the terms of GB/T 2900.33-2004 for ease of use and defines magnetic confinement fusion as the nuclear fusion reaction produced by using a strong magnetic field to confine high-temperature, high-density plasma for long enough, AC/DC converter as a power electronic converter used for rectification or inversion or both, semiconductor converter as one using semiconductor valve devices, and integration testing as the performance test of a complete converter system made up of semiconductor converter, rectifier transformer, DC switch and controller.

The page shows the front matter and these first three clauses only, and the draft stops before the requirements clause.

The standard was proposed and is managed by the National Nuclear Energy Standardization Technical Committee (SAC/TC58); the page lists the Institute of Plasma Physics of the Chinese Academy of Sciences, Rongke Hengyang Rectifier Technology Co., Ltd. and Huazhong University of Science and Technology as its drafting organizations, records it under ICS 27.120 and the Chinese classification F60, and traces it to National Standard Announcement No. 26 of 2020. It was issued on 2020-11-19 and has applied since 2021-06-01.
