Guangzhou Power Supply Bureau Distribution Network Innovation Technology Exchange Meeting and Haihong Electric Guangdong-Hong Kong-Macau Greater Bay Area Tour Exhibition (Guangzhou Station) was successfully held

    On November 19, 2020, Guangzhou Power Supply Bureau Distribution Network Innovation Technology Exchange Conference and Haihong Electric 2020 Guangdong-Hong Kong-Macao Greater Bay Area New Energy Efficiency New Technology and New Product Tour Exhibition Exchange Conference (Guangzhou Station) was held in Guangzhou Power Supply Bureau Electric Power Test Research Institute Held, this meeting was organized by the Production Technology Department of Guangzhou Power Supply Bureau and hosted by the Intelligent Power Distribution Department of Guangzhou Power Supply Bureau Electric Power Research Institute. Guangzhou Power Supply Bureau has jurisdiction over Baiyun Power Supply Bureau, Tianhe Power Supply Bureau, Haizhu Power Supply Bureau, Yuexiu Power Supply Bureau, Huadu Power Supply Bureau, Panyu Power Supply Bureau, Huangpu Power Supply Bureau, Nansha Power Supply Bureau, Zengcheng Power Supply Bureau, Conghua Power Supply Bureau, Liwan Power Supply Bureau, etc. More than 30 key technical experts from 11 regional bureaus attended the meeting.

    The first item on the agenda of the meeting was to carry out exchanges on the operation and maintenance technology of distribution network. First, the Guangzhou Electric Power Trial and Research Institute of the Guangzhou Power Supply Bureau publicized and implemented the technical standard system, and Liang Qingning, member of the National Transformer Standards Committee and chief technical engineer of Haihong Electric Co., Ltd. Interpreted the newly revised "Energy Efficiency Limits and Energy Efficiency Grades of Power Transformers" (GB 20052-2020), Mr. Liang conducted an analysis from five aspects: standard revision background, standard revision content, standard product development, policy support, and future development. elaborate. my country's distribution transformer loss accounts for 40% to 50% of the transmission and distribution loss, and the transmission and distribution loss accounts for about 6.6% of the national power generation. According to estimates, the power loss of distribution transformers in the country is about 230 billion kWh, which is equivalent to about 2.3 times the total annual power generation of the Three Gorges, and the power loss is very serious. Improving the efficiency of the entire distribution transformer system is of great significance for reducing the loss of power transmission and distribution in my country, promoting the transformation and upgrading of industrial development, and achieving the national goal of energy conservation and emission reduction. The power industry is gratified that the 2020 version of the new energy efficiency standard will be implemented on June 1, 2021, and the full text of the standard will be enforced. Mr. Liang pointed out that the implementation of new energy efficiency standards has the following significance:
(1) Effectively promote the elimination of high-energy-consuming backward power transformers, optimize the product structure of the industry, and power transformers that do not meet the energy efficiency limit value will be eliminated.
(2) Promote the promotion of high-efficiency, energy-saving and environment-friendly power transformer technology and products, and promote technological innovation in the power transformer industry.
(3) Promote the transformation and upgrading of the power transformer industry and the rapid development of the high-efficiency power transformer industry.
(4) Promote high-efficiency and energy-saving transformers, which will have a huge effect on energy conservation and emission reduction.
    After the release of the new energy efficiency standard, Haihong Electric has carried out research and development in terms of material selection, technology, and insulation structure according to the technical characteristics of the three-dimensional wound core transformer. At present, it has designed and produced typical products that meet the different performance requirements of the new energy standard. The developed products can be meet the standard requirements,It has also developed a super-level energy efficiency standard product that leads the new energy efficiency standard.

    The second item on the agenda of this meeting is the display of innovative technological achievements in distribution network, the integratedProtective open three-dimensional wound core dry-type transformerNew products such as miniaturized double-layer prefabricated substations, outdoor three-dimensional wound core open dry transformers, and intelligent on-load automatic voltage regulating transformers were all unveiled. The participating leaders and experts highly recognized Haihong Electric's technical research and development and innovation capabilities, and were very interested in the new technologies and products displayed this time. Through the detailed explanation of the new products by Haihong's technical engineers, the participating experts had a deeper understanding To Haihong Electric's long-term commitment to the research and development and manufacture of "safety, environmental protection, energy saving, and tranquility" power distribution equipment, it is believed that Haihong products perfectly solve the problems of urban land resource shortage and noise disturbance, and provide a solid foundation for product installation and maintenance. Great convenience, the experts spoke highly of Haihong's technical strength and innovative ideas of "dare to be the first in the world"! In the future, Haihong will continue to strengthen communication with the power grid to provide customers and the society with more energy-saving, green and environmentally friendly high-quality products, so that the "Haihongsheng" brand will become a bright business card recognized by the society!
