Photovoltaic Combined Transformer

Product overview： Product ZGS series new energy combined transformer is to meet the growing requirements of photovoltaic power supply, our company in the production of 35KV combined transformers based on the integration of advanced technology at home and abroad, combined with domestic demand to develop a series of products, the product is the transformer, load switch, high voltage fuse installed in the transformer box, The insulating liquid of the transformer is used as the insulating and cooling medium of the whole product, and the whole sealed structure is adopted, which has the advantages of small volume, lightweight and easy installation. Product characteristics： According to the different environments, different anti-corrosion processes are adopted to ensure the service life of the pre-assembled 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. Inlet and outlet cable wiring space and maintenance space are 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. 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 comprises 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.
