Wind Combined Transformer

Product overview: Wind combined transformer series products for our company specially designed and developed for wind power generation products, wind generator outlet voltage of 0.69kV, by 0.69/35kV transformer boost to 35kV, in the 35kv outlet side through a number of loops to form a joint unit, It is transmitted by 35kV cable line to 35/110kV booster station. The preassembled substation is a complete substation product that combines a booster transformer, high voltage switchgear, low voltage switchgear power transformer, and other auxiliary equipment reasonably with the box. Its performance is fully in line with GB/T17467 "high voltage/low voltage preassembled substation", which is a new type of preassembled substation developed for the special use requirements of wind power generation, with strong complete sets, easy installation, short construction period, low operating costs, high structural strength, anti-corrosion It has the advantage of strong performance and is fully applicable to the operating environment of beaches, grasslands, deserts, and other harsh natural conditions, and the performance fully meets the requirements of wind farms. Product features: The different use of the environment using different anti-corrosion processes to ensure the service life of the pre-installed substation. The overall layout of the box is compact, reasonable, and small in size. The connection between the main components is convenient, and the amount of copper bar is greatly reduced. The inlet and outlet cable wiring space and maintenance space is large and convenient for assembly and maintenance. Box structure: All metal structural parts are sandblasted, hot-dip galvanized, spray painting treatment, can ensure that the equipment in the wet, heavy salt spray environment uses its strong corrosion resistance, all door panels and wall panels, there is no sandwich, the middle filled with polyurethane and silicate composite insulation material, it has excellent thermal insulation performance, to ensure that the equipment in the cold environment safe and quickly put into operation. The transformer mainly adopts a three-phase double-winding oil-immersed no-load voltage regulation low-loss power transformer, and other types of power transformers can be configured according to requirements. The power transformer has adopted a series of reforms in the material, process, and structure, so that the electrical performance of the product has reached the advanced level of similar international products, and its no-load loss and load loss are lower than the national standards, with the characteristics of high efficiency and low loss, which can save a lot of power consumption and operating costs, and the social benefits are significant. The core is made of a high-quality cold-rolled grain-oriented silicon steel sheet with full oblique joint stacking and vacuum oil injection. The low-voltage side can use intelligent circuit breakers or other series of low voltage circuit breakers to distribute power and protect lines and equipment from overload, under-voltage, short circuits, single-phase grounding and other faults. At the same time, the low-voltage side is equipped with a small maintenance transformer to provide power for the maintenance site. The low voltage cabinet frame electric beams are treated with hot dip galvanized anti-corrosion.
