Helping the implementation of the new energy efficiency standard, the new energy efficiency standard "super class 1" transformer has been successfully developed!

    The new energy efficiency standard for transformers issued by the State Administration for Market Regulation and the National Standardization Management CommitteeGB 20052-2020 will be implemented on June 1, 2021, and the new energy efficiency standardIt is significantly better than the European Union, the United States, Japan and other foreign energy-saving standards, and the loss value of the transformer isSignificant drop on the basis of GB 20052-2013。

        In order to accelerate the implementation of the new energy efficiency standard, Haihong Electric has carried out a large number of research and development work on the energy efficiency improvement of the three-dimensional wound core transformer according to the performance index requirements of the standardGB 20052-2020, including the heat-resistant scored oriented silicon steel sheetTrial production, harmonic distribution analysis of three-dimensional wound iron core, optimization of iron core production process, and "Super Level 1" energy efficiency scheme, structure, process design and development according to the performance parameters of the new energy efficiency standard.

        At present, the first "Super Level 1" energy-efficient three-dimensional wound core distribution transformer (SB-M·RL-400/10-CNX1) for the new energy efficiency standard has been successfully developed, and the measured values of various performance indicators are much better than the new energy efficiency Standard: The measured value of no-load loss is 272W, and the measured value of load loss is 3021W. Compared with the first-level energy efficiency limit value of the energy efficiency standard GB 20052-2020, the no-load loss is reduced by 17.6%, the load loss is reduced by 7%, and the noise level is as low as 33 decibels; energy saving Environmental protection, outstanding performance, loss, noise and other indicators are at the international leading level.

        “超1级”能效The successful research and development of the three-dimensional wound core distribution transformer demonstrates the high-efficiency and energy-saving advantages of the three-dimensional wound core technology, and fully verifies the feasibility of implementing the new energy efficiency standard. Haihong ElectricAnother milestone on the road to "energy saving and emission reduction". Haihong Electric will make persistent efforts, actively respond to the national policy of "energy saving and emission reduction", and provide customers and the society with more green, energy-saving and environmental-friendly high-quality products!
