Recently, independently developed by Zhengtai Electric, China's largest-capacity, highest-voltage 40MVA, 132kV natural ester insulating oil transformer has successfully passed all types of tests at one time, filling the gap in domestic high-capacity, high-voltage natural ester-insulated oil transformer products.
The test was conducted under the testimony of a KEMA engineer in the third-party independent laboratory and an Australian customer representative, MSP. The test data meets or exceeds the customer's requirements and the IEC standard. It shows that Zhengtai Electric is in the high-end equipment manufacturing field again. Technological innovation and R & D and manufacturing strength.
It is understood that the Australian customer representative MSP, who has witnessed the testimony, is a well-known Australian power consulting company. It strictly implements the Australian power grid standards and has strict requirements on product parameters performance and environmental protection. This time, MSP purchases natural ester insulation for the first time in China. Oil Transformer, After a comparative analysis, Zhengtai Electric has stood out among many peers such as ABB, Siemens, Schneider and successfully collaborated with it.
The transformers developed by Chint Electric use natural ester insulating oil, which is environmentally friendly, biodegradable, non-pollution, high ignition point, high overload capacity, strong short-circuit resistance, low temperature rise, low noise, etc. The applicable area is also more extensive in the future. It can be applied to power plants in urban core areas with high environmental protection requirements, coal chemical power plants with high requirements for fire protection, underground power stations, large buildings or building power supply systems, iron and steel smelting, electroplating, etc., which require high overload energy in a short period of time. Industrial and mining enterprises and other fields.
'In the process of product R&D and design, the difficulty is not small, and it is easy to make a few changes', said Huang Hua, deputy chief engineer of Zhengtai Electrical Transformer Division. 'The transformer of natural ester insulating oil is in the electric field, magnetic field, and temperature field both with mineral oil transformers. Different, and foreign industry giants are very strict about this technical blockade. There is hardly any open data to use for reference. Therefore, from nothing, it has tested our R&D team. This successful development is based on our many years of development. The experience in developing various types of complex products also makes full use of high-end design simulation software, and also accumulated experience for our subsequent product development.
'This special, brand-new product can pass all type tests at one time, which is extremely difficult, but it also proves that Zhengtai Electric's R&D and design, production and manufacturing capabilities have an industry-leading level. 'Party witnessed in the third-party laboratory in the Netherlands KEMA The engineer said.
