China's first domestically-made low-noise transformer passed the national test center and Italy CESI certification
It is reported that China's first domestically-made low-noise transformer passed the national test center and Italy CESI certification, which will be delivered to the Netherlands national grid for use, opening a door for our power technology to go out of the country. As one of the region that has the most stringent environment protection in the world, Europe takes full account of environmental factors for the technical specifications of the various types of industrial equipment. The transformer also has strict standards as one of the major energy-saving power equipment. In the transformer running process, most of the noise does not belong to strong high-decibel noise, but the low frequency noises produced in the vast majority of cases will cause chronic injury to the human body, predisposes restlessness, irritability, and sometimes even irrational. In general, the tolerance of the people on the low-frequency noise is relatively low. Under normal circumstances, average person can accept 30-35 db, people would obviously feel palpitation, irritability uncomfortable situation if the noise is 35 dB or more.
 The low noise transformer will be used by Dutch national grid
This set of low noise transformer user is the Dutch national grid. As we all know, the Netherland is the famous "windmill country", whose clean energy accounts for a large proportion in domestic use, which is also an important part of the Western Europe economies. Therefore, the Dutch national grid posed a series of demanding technical requirements in the choice of transformer products, including airborne noise should be less than 51 decibels, better ability to withstand short circuit, installing optical fiber temperature measurement devices, which made many well-known domestic isolation transformer manufacturer prohibitive, unwilling to take the orders. When Dutch national grid contacted Chint, the company attached great importance and decided to seize the opportunity to win orders after convening technical agreement and assessed.
Ultra-low noise transformer design highlight
Another highlight is that the transformer no-load loss is only measured 26kW, in reference to in power transformers whose capacity is 63000kVA and voltage level of 110kV in national standards, the design of the no-load loss is 54.6kW, which is far lower than the standard value. It fully embodies energy efficient. In addition, ultra-low noise transformer install “hot fiber controller”, which will realize direct and dynamic measurement of transformer winding temperature, to start and cool equipment according to the actual hot spot temperature, maximum ensure the safe operation of the transformer. The chief engineer of the Division said that the internationally recognized certification bodies are Italy CESI and the Netherlands KEMA, Chint ultra-low-noise mains transformers passed CESI certification, and it fully displayed Chint transformer product design and manufacturing advanced level. Passing the international certification has strategic significance for further expanding the international market, especially in the European market.
Significance of China's first ultra-low-noise transformer
The birth of China's first ultra-low-noise transformer will also provide a very effective environmental protection support for our country's power network construction. Especially in the current stage when we are making great efforts to build smart grid, the use of such transformers will reduce noise pollution. At the same time, we know the ultra-low-noise transformer has the low energy consumption feature, in line with the energy conservation policy China strongly advocates, and will provide strong technical support for the construction of China's electricity.
