Recently, the first ±1100 kV 587.1 MVA converter transformer of the Changji-Guixue ±1100 kV UHV DC transmission project passed all the factory tests at Xichang Normal. China West Power Group has the highest voltage level in the world. , With the largest transmission capacity and the longest transmission distance, the transformer products provided by the most advanced UHV power transmission project have received much attention.
Recently, under the joint witness of the experts of State Grid and the experts of the Chinese Academy of Electric Power, the first unit of the Changji-Guoquan ±1100 kV UHVDC power transmission project of the group-owned enterprise West-West Power Transformer Co., Ltd. The KV 587.1 MVA Converter Transformer passed all the factory tests in a one-time pass in the West Ever-changing UHV test hall. The Changji-Guixue UHV transmission project will be the first in the world to perform DC transmission at a voltage level of ±1100 kV. This transmission project is the world's highest voltage class, the largest transmission capacity, the longest transmission distance, and the most advanced UHV power transmission technology, refreshing the new heights of the world's power grid technology. It has a significant demonstration of the development of the global energy Internet. effect.
In order to improve the overall technical capacity and meet the domestic demand for AC/DC transformers in voltage capacity, nuclear power plant construction and export of large-capacity products, the total investment of West Electric has been constantly increased by 1 billion yuan to implement the 'UHV transformer and reactor technical transformation project'. The total construction investment of 570 million yuan will be put into operation in 2017. The new construction area will be approximately 28,000 m2, of which the construction area of the UHV production plant will be approximately 12,000 m2, and the designed production capacity will be increased by 13.3 million kVA. During the project construction, the company will constantly change its personnel, Funds, construction equipment, construction management, and other aspects are taken into consideration. The construction of technological transformation projects will be coordinated and arranged to ensure the production progress of the 'Changji-Guixue' project. The test hall will use energy-saving, reliable and efficient equipment and measuring instruments to improve efficiency. Transformer digital laboratory test equipment and measurement and control systems, measurement and control equipment to achieve domestic and international first-class level.
The height of the new workshop is more suitable for the final assembly and testing of transformers. The field technicians said so. The reporter saw on the scene that a transformer for the Guquan project was under test and two Siemens experts guided the entire process. After that, it has basically broken through the early stage technical difficulties and is now entering the stage of steady volume manufacturing'. Field technicians told the reporter that the test is generally conducted in more than 7 days and will measure and control the transformer from various aspects.
It is reported that the three key projects of 'changji-guquan', the 'changji mountain' of Brazil, and the 'Yi'e' of Brazil are being carried out at the same time. Among them, the 500kV 40 mn volt-ampere station developed and manufactured for the communicative project of shanghai dc back-to-back network. All the performances of the products have met or exceeded the requirements of the national standards and technical agreements with transformers through all factory tests; Brazil's 'Beautiful Mountain' ±800kV UHV transformer-changed six units have been successfully delivered and delivered. Beautiful Mountain Project in Brazil It is China’s first UHV DC transmission project that won the bid overseas. It is a new milestone in China-Pakistan power cooperation and marks a major breakthrough in China's UHV transmission technology 'going global' and is China’s leading world leader in high-end manufacturing. Zhang's 'business card' will further promote China's UHV transmission technology and equipment to go abroad, and at the same time it has important international significance for promoting the expansion of China-Pakistan economic and trade cooperation.
At present, as a key landmark project to promote the 'One Belt and One Road' initiative, UHV, smart grid technology upgrades and innovations have risen to national strategies, and China has mastered UHV core key technologies, achieving the goal of 'creating from China' to 'leading China'. The leap of Xi'an Electric Power Co., Ltd. is the only company in China that has mastered the technology of AC transmission and transformation 1000kV transformers and DC transmission ±1100kV converter transformer technology and the leading company in the province's power transmission and transformation industry. As a regular central enterprise, Xichang Changxing will continue to shoulder the important mission of revitalizing the major equipment manufacturing industry in China, further promote the overall upgrading of the supporting capacity of the surrounding power transmission and transformation industry chain, and expand the visibility and industrial clustering effect of Changzhou City in the entire power transmission and transformation industry. , To the 'Belt and Road' countries and regions along the line show Changzhou as 'the world of transformer manufacturing capital' charm.
