China West low noise 220kV transformer made a breakthrough

Recently, China Western Electric (220) reported that 220kV low-noise transformer developed by Zhejiang Taizhou Shan'an Substation passed the test successfully. The measured no-load noise is 56dB and the load noise is 59dB, both of which are better than the contractual requirements.

The project is the State Grid Corporation of infrastructure technology research and application projects - low noise transformers rely on the project. In order to successfully complete the project and promote the implementation of the project, in April 2013, China Western Electric Power and Tsinghua University jointly launched the project "Research on Application of Vibration and Noise Reduction Techniques for Power Transformers" and conducted a special project on noise reduction of transformers the study.

In the transformer design stage, the control of magnetic density, the selection of 6 joints special cross-section of the core, to optimize the distribution of ampere-turns, and enhance the overall stiffness of the tank and a number of noise reduction design and manufacturing process used in the body metal rubber buffer Devices, insulation noise isolation board, the basis of vibration isolation devices, the transformer noise reduction and noise reduction ancillary measures organic combination.

The successful development of this product indicates that China Western Electric made a major breakthrough in the development of low-noise transformers and provided strong support for opening up a broader market in the future.
