After four years of product technology development, Baosight has recently launched medium and large capacity high-performance variable-frequency products through successive autonomous R&D. This signified Baosight took the lead in high-end technology of variable-frequency drive, and made remarkable innovative contribution in breaking technology monopoly by foreign countries and filling domestic gap in China.
Medium and large capacity high-performance variable-frequency products of Baosight launched through successive autonomous R&D this time include large capacity high-performance tri-level variable-frequency device 3.3KV/10000KVA mainly applied in main drive system of steel rolling; and the medium capacity high-performance multilevel drive variable-frequency device 690V, 380V/400~3000KVA mainly applied in auxiliary drive and processing lines of steel rolling. Baosteel Co., Ltd. greatly valued the product. During launching and communication meeting held by Baosight recently, Equipment Department of Baosteel Co., Ltd. organized chief electrical engineers and specialists from all manufacture plants and departments of Baosteel Co., Ltd. to engage in communication, research and discussion, and visited the operation demonstration of the sample charged machine unit of high-performance medium capacity variable-frequency drive (see photo). Technical specialists highly praised Baosight medium and large capacity high-performance variable-frequency products and provided valuable suggestions for product future development and application.
To take the lead in developing high-end technology of variable-frequency drive, break technical monopoly by foreign countries as soon as possible, Baosight organized and established a specialized R&D team of high-end technology of variable-frequency drive. In four years' time, the R&D team had gone through complex technical R&D processes of control and model building, algorithm research, off-line emulation, real-time emulation, emulation/converter/electric motor system experimentation, DSP control hardware research and manufacture, etc., tackled a series of highly difficult technical issues, and finally achieved breakthrough results in area of high-end technology of variable-frequency drive. Product technical properties and functionality reached levels equivalent with products of the same grade in foreign countries. R&D progression and achievements of Baosight medium and large capacity high-performance variable-frequency product control system technology excel those of domestic counterparts. Successful autonomous R&D of medium and large capacity high-performance variable-frequency products also signified a new page in domestic substitute for imported products of high-performance variable-frequency electrical drive in iron and steel industry.
Baosight mentioned, to enhance product autonomous R&D capability and implement product strategy were important measures for Baosight to carry out the new-round development plan and realize the dream of reaching "ten billion". In the next phase, Baosight would further propel industrialization and market application of medium and large capacity high-performance variable-frequency products to provide service for iron and steel industry and continuously expand product implanted coverage and appliance in industries of suburban railway transportation, nonferrous metallurgy, paper-making, etc..
