TBEA Shenbian Company is the earliest enterprise in China to develop and produce 500kV transformers, which has created many firsts in the development of China's electric power industry and pioneered the technological upgrading. With the National Transformer Technology Center, dozens of scientific and technical personnel enjoy government subsidies, and many old experts such as Mr. Yao Xing are employed as senior experts and consultants by State Grid Corporation of China. For a long time, TBEA Shenbian Company has always insisted that "ensuring the core competitiveness of independent research and development of enterprises" is the foundation and cornerstone of long-term sustainable development of enterprises, continuously increased investment in new product development and scientific research, and cooperated with Tsinghua, Xi Jiaotong University, Harbin Institute of Technology, Shenyang University of Technology, harbin university of science and technology and other well-known domestic universities and worked in the Institute of Atomic Energy for a long time. In each "Five-Year Plan", TBEA has undertaken major research achievements and achieved a large number of independent intellectual property achievements. While insisting on independent research and innovation, we also constantly absorb and introduce foreign advanced transformer manufacturing technology. Since 1980s, the design and manufacturing technologies of 500kV large transformers from Alstom Company of France and Hitachi Company of Japan have been introduced successively. From the 1990s to the new century, through technical cooperation and project cooperation, the design and manufacturing technologies of major foreign transformer manufacturers such as Siemens in Germany have been studied and introduced. In 200 1 year, a set of 350kV~ 1 150kV UHV design and verification technology was successfully introduced from Zabrozh Transformer Research Institute in Ukraine. By integrating advanced technology, the ability of independent innovation has been greatly accelerated. On August 15, 2008, the National Development and Reform Commission officially approved that TBEA Shenbian Company and Shenyang Transformer Research Institute would jointly implement the "National Engineering Laboratory Construction Project of UHV Substation Technology". On September 12, the National Development and Reform Commission held a ceremony to officially award the license. This is the only national engineering laboratory in China transformer industry, the first national engineering laboratory in Liaoning Province and the first national engineering laboratory in Shenyang. The approval to implement this project is the country's full trust and affirmation of TBEA Shenbian Company's independent innovation capability, which indicates that TBEA Shenbian Company has become a leading enterprise in independent innovation of China transformer industry. The further implementation of this project will promote the leap-forward improvement of TBEA Shenbian Company's independent innovation capability, improve the attractiveness of enterprises to high-end talents in the industry, form an agglomeration effect, and promote TBEA Shenbian Company to continuously master the core technology of the industry and become a leader in the technological development of China and even the world.
The internal structure and shielding measures of UHV and UHV test halls of TBEA Shenbian Company are designed and built according to the current international advanced technology. The main test equipment is air cushion moving, and the samples in the hall are also moved by air cushion car. The main test equipment and measuring instruments are produced by famous companies at home and abroad. Good test conditions and advanced test equipment and measuring instruments have greatly improved the test efficiency and technical level, and enabled the museum to test UHV and large-capacity power transmission and transformation equipment.
Effective space in the EHV test hall: length× width× height: 70× 40× 33m. The width× height of the product entrance door is: 1 1 × 17m. Hall grounding resistance is 0.08 Ω. The hall has good electromagnetic shielding and sound shielding efficiency. Electromagnetic shielding is composed of copper mesh and metal conductor, and the shielding effect can reach 65dB. All doors are integrated with a shielding system. Therefore, the background interference level can be as low as 10 pC when the broadband method is used for partial discharge tests of transformers and reactors. The good sound insulation function of the hall makes the background noise level during sound level measurement not exceed 40 dB(A). The laboratory has a controllable central air conditioning ventilation system, which is conducive to ensuring a better test environment. This laboratory is equipped with an automatic control system and a multi-point hook at the top of the laboratory, which simplifies the test steps and improves the test efficiency. There are two independent test benches in the lobby, which can test two products at the same time.
The final electrical performance tests of transformers, reactors and other products are conducted in this hall. These tests include: routine test, type test, special test except short-circuit ability, etc. The test is conducted in strict accordance with the user's technical agreement and corresponding standards, mainly including Chinese national standards, IEC standards, American national standards and other national standards.
The test hall has the following test capabilities:
Dc products:
1000KV large-capacity converter transformer, smoothing reactor, etc.
Communication products:
1000KV large-capacity transformer, reactor, controllable reactor, etc.
Other special project tests and research tests
Excellent test environment and precise test equipment and instruments not only meet the current test requirements, but also meet the test requirements of electrical products with larger capacity and higher voltage grade in the future. The performance of large-capacity products provides valuable manufacturing experience for our company. TBEA yang shen Transformer Group Co., Ltd. started mass production of 500 kV transformers in 1980s, and developed a million-volt transformer at the end of 1990s. Thousands of high-quality 220kV~ 1000kV transformers have been provided for several national key projects, and rich experience in process manufacturing has been accumulated. A large number of skilled professional and technical workers have been trained.
