JB/T7826.3—1996
This standard is formulated to adapt to the production, development and application of thyristor modules and actively adopt international standards. The technical requirements and parameter indicators of this standard adopt the general level of similar foreign products. The setting of the inspection items of this standard is based on the performance requirements of thyristor modules, and refers to the national standard GB4940 "Ordinary Thyristors" and has made some additions and deletions.
The test methods adopted in this standard, in addition to JB/T7625-94 "Test Methods for Thyristor Modules", the test methods for discrete devices are implemented in accordance with GB4024 "Test Methods for Reverse Blocking Triode Thyristors of Semiconductor Devices". In order to ensure the product quality of thyristor modules, this standard stipulates that at least one batch of temperature change tests should be conducted every six months. Appendix A and Appendix B of this standard are both standard appendices. This standard is proposed and managed by the Xi'an Power Electronics Technology Research Institute of the Ministry of Machinery Industry. The drafting units of this standard are: Yangzhou Siling Electronics Co., Ltd., Wuxi Radio Component Factory No. 5, Beijing Chunshu Rectifier Factory, Xiangfan Instrument Component Factory, and Fuxin Transistor Factory.
