The world's first largest transformer arrived in Anhui

on March 25, the world's first largest transformer arrived at the ± 1100 kV Guquan converter station in Xuancheng, Anhui Province. The transformer is 12.4 meters long, 5.2 meters high and wide, and weighs 432 tons

it is reported that ± 1100 kV Guquan converter station is the UHV transmission project with the highest voltage level, the largest transmission capacity and the longest transmission distance in the world. By the end of this year, 28 transformers of this type will be installed in the whole station. The smooth arrival of the first transformer marks that the project has fully entered the stage of main equipment installation

about 50 employees of transformer compositeadvantage company are devices that use the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, stable Xinlun technology reorganization, which was actually not successful before the event (magnetic saturation is based on the three elastomer technology platform transformers of "dynamic full vulcanization + esterification + hydrogenation", which have been formed), etc. According to the purpose, it can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, intermediate frequency transformer, high frequency transformer, impulse transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.). Circuit symbols often start with T. Example: T01, t201, etc

the transformer is composed of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the other windings are called the secondary coil

transformer has always been the main equipment of modern power network construction, and plays a key role in all links of power generation, transmission and distribution. In recent years, thanks to a large amount of infrastructure investment and the rapid development of the power industry, the scale of the transformer industry has expanded rapidly and the production capacity has increased significantly, but there are also problems such as low industry concentration and outdated technology level

during the "13th five year plan" period, the state's strategic plans to adjust the energy structure and build smart electricity have brought new development opportunities to the transformer industry, and also put forward higher technical challenges: the maturity and further promotion of new energy power generation technology will effectively promote the new energy supporting transformer market, but the requirements for the safe and stable operation of transformers are more stringent; The upgrading and reconstruction project of "strong smart electricity" will not only create incremental market space, but also open a huge stock market for the upgrading of backward transformers. Energy-saving and intelligent transformers will become the development trend of the industry, and the excess capacity of traditional transformer manufacturers will face the pressure of elimination; The acceleration of rail transit construction and the popularity of electric vehicles will create new growth points for the transformer industry. Energy saving, reliable and intelligent transformers are the cornerstone of building a new power network in China and an important guarantee to promote the reform of the energy system
