Good news about technological innovation

In April 2017, Haihong Electric Co., Ltd. won two more honors: the three-dimensional wound core H-class insulated non-encapsulated dry-type power transformer won the first prize of Jiangmen Science and Technology Award, and the dual-voltage three-dimensional wound core dry-type transformer won the Guangdong Province The third prize of the Machinery Industry Science and Technology Award.

Scientific and technological innovation should meet the needs of national development. The two technological innovation achievements awarded this time are both in line with the actual needs of the development of my country's power system in the new era.

The three-dimensional wound core H-class insulated non-encapsulated dry-type power transformer has the characteristics of high insulation and heat resistance, strong fire prevention capability, and strong overload operation capability. It can run deep into the load center and is suitable for high-rise buildings, commercial centers, industrial and mining enterprises, and oil platforms. Power transmission and transformation systems in places such as subways and tunnels. The hybrid insulation technology composed of DuPont NOMEX insulating paper and German Alentas paint is adopted. NOMEX paper has the advantages of flame retardancy and easy degradation. It will not release harmful gases below 750 ° C, which is in line with the current green environmental protection advocated by the country. strategic development route.

The research and development project of the dual-voltage three-dimensional wound core dry-type transformer is based on the current status of the voltage level of the medium-voltage distribution network in my country from 10kV to 20kV. The medium-voltage distribution network is boosted from 10kV to 20kV, which can reduce line losses by four Third, save the number of substations and land and reduce the space of line corridors. It may take 20-30 years or even longer for the voltage level of the medium-voltage distribution network to change from 10kV to 20kV. During this period, there will be two voltage levels of 10kV and 20kV in most power supply areas. The transformer can avoid secondary investment and meet the needs of power grid construction.

The honor is the affirmation of Haihong Electric's development path of scientific and technological innovation, and it is also an encouragement to keep innovating and surpassing.
