Haihong New Product Technology Exchange Conference was successfully held in Kunming

         In Kunming in June, the sky is clear and blue, sparkling with waves. Known as the "Pearl of the Plateau", the Dianchi Lake - Xishan District, Kunming, Yunnan Province, where China's first hydropower station, first cable, first machine gun and other "firsts" were born. It is the birthplace of China's modern industry It is also one of the famous industrial bases in Yunnan. Here will also be the first safe, environmentally friendly, energy-saving and quiet outdoor open-type three-dimensional wound core dry-type transformer hanging network demonstration project in the plateau area, which is fully in line with the environmental protection and sustainable development of the plateau strongly advocated by the local government Requirements for the construction of lakeside eco-city.
         On June 12, 2020, Haihong Electric Co., Ltd. held a technical exchange meeting for new products such as outdoor open three-dimensional wound core dry-type transformers in Kunming Xishan Power Supply Bureau. The meeting invited technical experts from Electric Power Research Institute of Yunnan Power Grid Corporation, leaders and experts from Kunming Xishan Power Supply Bureau of Yunnan Power Grid Corporation, experts from Yunnan Electric Power Technology Corporation, experts from design institutes and installation units, and technical experts from Haihong Electric Co., Ltd. The team discusses together. The meeting officially started at 9:30 in the morning. The leader of Kunming Xishan Power Supply Bureau of Yunnan Power Grid Corporation presided over the meeting, made an opening speech and introduced the participants. On behalf of the company, the Director of Market Development Department of Haihong Electric Co., Ltd. thanked all the leaders and experts who attended the meeting for coming to the venue for guidance and exchange.

        The chief technical engineer of Haihong Electric Co., Ltd. gave a detailed introduction to the technical characteristics of outdoor open dry transformers. At present, oil-immersed transformers are widely used in outdoor environments. Since oil transformers use mineral oil as the insulating medium, oil leakage and oil leakage are prone to occur. , carbon deposition, rust, combustion, explosion and other problems. In addition, the domestic transformer industry has oversupply, overcapacity, low industry entry barriers, chaos such as the use of secondary chips, tolerance tolerances, and uneven product quality. Potential safety hazards, prone to breakdowns, and in serious cases, combustion or even explosion accidents will occur, endangering the personal and property safety of the people. Based on this background, Haihong Electric has developed the world's leading outdoor open-type dry transformer. The main body adopts a three-dimensional wound core structure, which has the characteristics of high efficiency, energy saving, green environmental protection, safety and reliability. It can be directly used in outdoor places and can overcome oil immersion. Type transformers are prone to oil leakage, oil leakage, rust and other problems, reduce the daily maintenance of transformers, and prevent combustion or explosion accidents caused by product failures. Production cost, use economy and many other advantages. There are many tourist cities in Yunnan Province. The tourist attractions have a large flow of people. In terms of architectural style, there are many wooden buildings or decorations. Once a fire occurs, the consequences will be disastrous. Therefore, it will be the safest and most secure choice to adopt an outdoor open-type three-dimensional wound core dry transformer with fireproof and waterproof performance.

Advantages of Haihong Outdoor Open Dry Transformer Technology

        The participating leaders and experts had a heated and in-depth exchange and discussion on the technical characteristics of Haihong's outdoor open dry substation, and believed that Haihong's outdoor open dry substation is very suitable for grid-mounted demonstration operation in Kunming Xishan Bureau. At the meeting, the chief engineer of Shanghai Hong Technology also shared the technical characteristics of the company's new products such as miniaturized double-layer box transformers and intelligent transformers, which received strong responses and unanimous praise from the leaders and experts present at the meeting. In addition, at the meeting, technical experts from the Electric Power Research Institute of Yunnan Power Grid Corporation shared the failure cases of power equipment that had occurred in the power grid, focusing on several failures that occurred during the operation of epoxy resin casting dry conversion. In this regard, technical experts from Haihong Also from a technical point of view, the advantages and disadvantages of the epoxy resin cast dry transformer and the open three-dimensional wound core dry transformer were compared and analyzed. Experts recognized Haihong SGB dry transformer very much and gave a high evaluation. In the case, it also reflects the urgent demand of the power grid for the safety and reliability of power equipment.
        After the symposium, the physical product display link was carried out. The technicians of Haihong Electric demonstrated the noise test and water spray test of the open three-dimensional wound core dry transformer to the participating leaders and experts on the spot: the environmental background noise measured in the exhibition car 41 Decibels, the noise measured by the open dry variable noise test is also about 41 decibels (in the quiet environment of the laboratory, the measured noise of Haihong ultra-low silent dry variable can be as low as 38 decibels), which perfectly demonstrated the open three-dimensional volume to the people present. Ultra-low noise characteristics of iron-core dry-type transformers. The water test of the open dry transformer is to conduct a power frequency withstand voltage test for 1 minute after the surface of the product is fully sprayed with water. The on-site withstand voltage test passed successfully, which shows that the open three-dimensional wound core dry-type transformer can be used in the special environment of high altitude. , the moisture-proof and waterproof performance is still very reliable.
