"China Instrument Network Instrument Development" "The successful development of large-scale energy-saving core traction transformer companies, in the country and even the world we can say is the first." Changzhou, Jiangsu Changzhou Electric Power Equipment Group Chairman Gao Jidong proudly introduced.
Recently, 220KV/56.5MVA large-scale energy-saving rolling iron heart traction transformers jointly developed by Changzhou Pacific Power Equipment Group, School of Electrical Engineering of Southwest Jiaotong University and China Railway Engineering Design Consulting Group Co., Ltd. have successfully passed the technical review hosted by China Railway Corporation. The experts all agreed that the key technologies of high-voltage, large-capacity, energy-saving wound iron core traction transformer developed by Changzhou Pacific Electric Power Equipment have reached the international advanced level.
It is understood that the rail transit traction transformer is a special-purpose power transformer and is one of the most critical equipment for electrified railway projects. It is known as the “heart†of electrified railways. Since 2003, China's three-dimensional coil core transformers have gradually become popular, especially in the transmission and distribution systems, and can be used to mass produce coiled core transformers up to 35KV. However, the study of 110-220KV class three-dimensional coil core transformers is still in the global scope.
Gao Yudong introduced that as early as 2013, they began to cooperate with Southwest Jiaotong University to develop large-scale rail transit traction transformers. In 2015, the project was supported by China National Railway Corporation. Changzhou Pacific Power Equipment Group, Southwest Jiaotong University Electrical Engineering Institute and China Railway Engineering Design Consulting Group Co., Ltd. jointly developed successfully, and conducted a one-year grid-connected operation. Up to standard.
Gao Jidong introduced that the 220KV/56.5MVA intelligent wound iron core rail transit traction transformer has the advantages of ultra-low loss, large capacity, energy saving and environmental protection, and adopts intelligent manufacturing technology to solve the production process of high-voltage coil core traction transformers, iron core winding, Iron core annealing, transformer assembly movement and other issues, no-load loss reduced by 50%, noise decreased by 20 Dolby, cost reduction by 15%. At the same time, through the integration of sensing and monitoring equipment on the transformer, an early warning analysis model and an empirical knowledge base are established. In the field of railway traction power supply, the intelligent early warning analysis of the entire operation of the transformer is first realized, and the failure rate of the railway special transformer is greatly reduced.
“Roll core transformer technology is a mature technology, but 220KV grade large core transformers have been left blank at home and abroad due to limitations in process and production equipment.†Gao Jidong introduced that Changzhou Pacific Power Equipment Group is the only one at home and abroad. Mastered the design and manufacturing technology of the 220KV volume core transformer and the only unit with independent R&D and production processing equipment.
According to estimations, if a railway core traction transformer is used in China, it can save 840 million kWh (degrees) of electricity each year, and this alone can save nearly 1 billion yuan in electricity costs. When the relevant technology is mature, if it is promoted to AT transformers and power transformers, it can save more than 1 billion kWh of electricity each year and save 800 million yuan in electricity costs. “Our new plant has been basically completed, and the production equipment for the large-capacity rolling-core rail transit traction transformer is also being installed. We expect it to be put into production within this year.â€
