Haihong Amorphous Alloy 3D Wound Core won the China Patent Excellence Award

Recently, Haihong Electric Co., Ltd. received the "China Patent Excellence Award" certificate issued by the State Intellectual Property Office.The 3D triangular structure amorphous alloy transformer core independently developed by the company won this honor. The China Patent Award is established by the state to encourage and commend patentees and inventors (designers) for their outstanding contributions to technological (design) innovation and economic and social development. The China Patent Award is selected by the State Intellectual Property Office and World Knowledge Jointly carried out by WIPO, it is held once a year and selected from the aspects of patent quality, technological advancement, application and protection measures and effectiveness, social benefits and development prospects. Haihong Electric's winning this honor marks the country's recognition of the novelty, creativity and advancement of Haihong's self-developed amorphous alloy three-dimensional wound core, and it also fully affirms the ownership of Haihong's own technological intellectual property rights.

Since 2010, Haihong Electric established a project to research and develop amorphous alloy three-dimensional wound core oil-immersed transformer. After more than two years, more than 300 R&D and trial production plans, and invested more than 20 million yuan, finally independently developed the world's first amorphous alloy three-dimensional transformer. Wound core oil-immersed transformer, and passed all product tests in August 2012. In 2016, the company successfully developed an amorphous alloy open three-dimensional wound core dry-type transformer, and made a new breakthrough in the research and development of amorphous alloy transformers.

Haihong Electric's world's first amorphous alloy three-dimensional wound core transformer is a perfect combination of the structural advantages and magnetic circuit advantages of the three-dimensional wound core and the low iron loss advantages of the amorphous alloy strip. Compared with the national standard, the no-load current average Reduced by 60% to 80%, no-load loss by 10% to 35%, and average noise reduction by 5dB(A) to 8dB(A), with low loss, strong short-circuit resistance, low operating noise, low temperature rise, strong iron core, Reusable and other advantages. In addition, the amorphous alloy three-dimensional wound core oil-immersed transformer can greatly save power loss, reduce CO2 and SO2 exhaust gas emissions, reduce environmental pollution and the harm caused by the greenhouse effect, and have significant social benefits. After the product was launched, it was recognized by the power grid company and customers. In 2016, the sales volume in China Southern Power Grid alone exceeded 5,000 units, and all of them passed the previous sampling inspections of the power grid company. At present, more than 13,000 units of the series of products have been connected to the network and have excellent operation records.

The amorphous alloy 3D wound core transformer is a product independently developed by Haihong Company. The company also attaches great importance to the protection of intellectual property rights. At present, this series of products has obtained 22 authorized patents, of which 8 are international invention patents. The amorphous alloy transformer project obtained the certificate of the national torch plan industrialization demonstration project, and the amorphous alloy transformer products were included in the power grid company's key promotion of new technologies and new products; it was selected into the "Energy Efficiency Star" product catalog (2016) and "Energy Efficiency Star" published by the Ministry of Industry and Information Technology Recommended catalog of energy-saving mechanical and electrical equipment (products) (sixth batch)".

On April 4 this year, General Secretary Xi Jinping made important instructions on Guangdong's work, proposing "four persistences, three supports, and two at the forefront". For enterprises, they must follow the instructions of General Secretary Xi and adhere to the new development concept , Implement the innovation-driven development strategy. Technology research and development and continuous innovation are the magic weapons for the development of Haihong. In the future, Haihong will always adhere to the road of scientific and technological innovation, develop more and better energy-saving products, and contribute to the national Belt and Road Initiative and energy conservation and emission reduction.
