Recently, Schneider Electric, a global energy efficiency management expert, announced that it has provided energy efficiency solutions centered on medium-voltage inverter products for Unit 3 and Unit 4 of Nuclear Power Group Co., Ltd. (hereinafter referred to as Sanmen Nuclear Power) Medium voltage inverter products for the first time in the field of nuclear power applications. Sanmen Nuclear Power Station is China's first three generations of nuclear power relying on independent projects, using the world's leading third-generation nuclear power technology AP1000. In the project, Schneider Electric's ATV1200 10KV medium voltage inverter products will be mainly used in frequency conversion speed regulation of seawater membrane reverse osmosis Booster Pump. Developing nuclear power to increase the proportion of clean energy is an important development strategy for promoting energy conservation and optimizing energy structure in our country. However, as safety-related information receives more and more attention, nuclear power development has also encountered enormous challenges. The Chinese government promulgated "Nuclear Safety Plan (2011-2020)" and "Medium and Long-Term Nuclear Power Development Plan (2011-2020)" this year, all emphasizing that the principle of "safety first" should be implemented in nuclear power planning and construction , Operation, retired the whole process and all related industries. In this project, Schneider Electric provided the ATV1200 medium voltage inverter for the three nuclear power plants and adopted the most mature technology of medium voltage frequency converter - 'multilevel series' to achieve medium voltage output. Ensure that the motor and equipment run smoothly and safely. In addition, the ATV1200 can effectively reduce system energy consumption, thereby reducing the plant's electricity rate throughout the plant. "Nuclear power has always been an area of ​​great concern for Schneider Electric and we already have proven technologies, products and solutions in place to prove that it is a good testimony to the construction of the world's leading nuclear power plant." In this project, our ATV1200 The performance parameters of inverter products meet or exceed the requirements of customers and are equipped with excellent after-sales service support and fully recognized by Sanmen Nuclear Power Co. The market of nuclear power in China has great potential for development, National Development and Reform Commission explicitly emphasized in the end of 2012 that "China's determination to develop nuclear power will not change." In the future, Schneider Electric will continue its investment in this field and hope that all sectors in the industry can work together to build China into a leading nuclear power market in the world. "Schneider Electric Senior Vice President Xu Jun, president and head of the industrial division, said. Schneider Electric ATV1200 is a response to the call of energy-saving emission reduction products developed and has been successfully applied in many industries. It consists of transformer cabinet, power unit cabinet, control cabinet composed of three parts, the input using 24 to 48 pulse rectifier, current harmonic distortion rate THDi less than 2%, almost no harmonic; nearly perfect sine wave output - "clean and friendly" The design reduces the mechanical vibration of bearings and blades, which can effectively protect the motor and equipment. Its main controller based on DSP, FPGA, CPLD and other contemporary most advanced electronic devices, computing speed, reliable work. In addition, ATV1200 also built-in grid synchronization switching, PID, Speed ​​starter, synchronous motor excitation control applications. CNNC Sanmen Nuclear electrician process used by the US Westinghouse developed the third generation nuclear power technology AP1000, planning and construction of six 1.25 million kilowatts of nuclear power units with a total installed capacity of 7.5 million kilowatts, built in three phases, is expected to be fully completed by 2020, A total investment of more than 100 billion yuan. The first phase started on April 19, 2009 and its No. 1 unit is the world's first AP1000 nuclear power unit. nitrogen purification,psa nitrogen purification,purification plant Tiancheng Mechanical And Electrical Co., Ltd. , http://www.hzlagenerators.com
