Recently, Jiangsu Changzhou Toshiba Transformer Co., Ltd. has independently developed two 1,330 MVA/500 kV main transformers for Indonesia's Java 7 project, the One Million-Watt Ultra-supercritical unit under construction. Sex passed the test and created the record of the successful development of China's first 1330MVA three-phase transformer with the largest capacity.
Founded in 1995, Changzhou Toshiba Transformer Co., Ltd. is a Chinese-foreign joint venture that is owned by Shandong Electrician Electric Group Co., Ltd., a subsidiary of the State Grid Corporation of China, and Japan’s Toshiba Group, and develops and produces power transformers at various voltage levels. The main products of transformer switch parts and components are China's first joint venture company to develop and produce 500kV voltage grade power transformers. It has 3 invention patents and 24 utility model patents.
On January 16, 2017, the foundation project of Java No. 7 project in Indonesia was formally started. This project is an important achievement of China's Shenhua Energy Co., Ltd. 'Going Global' strategy. It is also the largest unit with the largest single capacity in Indonesia and Chinese enterprises overseas. The unit with the largest capacity for export single unit, the construction standard will regard China GB series standards and European, American and Japanese standards as international common standards with a total investment of 1.883 billion U.S. dollars. It is planned that unit 1 will complete COD before April 7, 2020, before October 7, 2020. Unit 2 completes the COD.
In the face of high design standards and stringent requirements from owners, Changzhou Toshiba Transformer Co., Ltd. has overcome the difficulties of fuel tank hotspots caused by large capacity, large current, etc., and finally determined a safe and reliable design scheme. , Strictly require, unite and cooperate, overcome difficulties, manage and control all key points comprehensively, make every detail carefully, and do a good job of 'five preventions' (anti-UV, anti-high temperature, anti-high humidity, anti-salt spray, anti-thunderstorm) , 'Four zero' (zero defects, zero pieces, zero delays, zero loss) work, and successfully achieved a major goal of 'a successful test', and made positive contributions to the construction of the project.
In addition, under the supervision of the user and the third-party power company's entire site, the five transformers including the two main transformers passed the test all at once, which was highly recognized by the users.
The successful development of the transformer has accumulated rich experience for key technologies such as the design and manufacturing of super-large generator transformers and Changzhou Toshiba Transformer Co., Ltd. It has established a leading position in the industry. At the same time, the completion of the project will play an important role in promoting the local economic development in Indonesia. Role, and effectively promote China and Indonesia in the depth of follow-up investment and construction cooperation.
