Model Number and Meaning
Products
Photovoltaic power generation is a kind of clean and renewable energy, which is developing rapidly at home and abroad. ZGS20-Z-G series combined transformer is precisely to meet the growing power supply requirements of photovoltaic power generation, on the basis of 10KV and 35KV combined transformer, after years of exploring and summarizing, digesting and absorbing the domestic and foreign advanced technology, combining with photovoltaic power generation on the special requirements of the transformer, the series products are developed and developed by ourselves. Research and development of a series of products, the product is the transformer, load switch, high-voltage fuse installed in the transformer box, the use of transformer insulation liquid as the insulation and heat dissipation medium of the entire product, the use of fully sealed structure, the body of the transformer adopts medium-thick steel plate, the shell uses galvanized plate or stainless steel plate, after the spraying of shot blasting, pickling, phosphating, respectively, spraying primer, intermediate paint, paint to achieve the surface of the anticorrosive properties, Thickness resistance, ultraviolet resistance are more than the strength of ordinary spraying, with small size, light weight, easy to install and other advantages.
Product Main Features
1, Compact structure, small volume, small footprint, only 1/3 of the same capacity of European box variable.
2, Low loss, low noise, strong resistance to sudden short-circuit capability;
3, Fully insulated, fully sealed structure, can be maintenance-free, safe and reliable operation.
4, Reverse gate operation is convenient and flexible.
5, complete protection, high pressure full range fuse protection;
6, The box body is treated with special technology and special material treatment, which has good anti-corrosion ability and can effectively prevent the erosion of wind and sand;
7, the box arrangement is divided into “L” shape and “eye” shape two kinds.
10kV Class Combination Transformer
By the high-voltage backup current-limiting protection fuse and plug-in overload protection fuse used in series, to provide a full range of protection for the transformer, high-voltage current-limiting protection fuse as the short-circuit protection of the transformer, plug-in overload protection fuse as the American-style power transformer and other power equipment this load and small fault short-circuit current protection.
35kV Class Combination Transformer
A new type of high-voltage current-limiting fuse for full-range protection is adopted, which can reliably break any fault current between the current caused by melting of the melt and the rated breaking current, and it makes use of the current-limiting fuse with high breaking capacity and the non-current-limiting fuse with good small-current protection characteristics, and combines the different characteristics of the two types of fuses and combines them into one to obtain the good characteristics of full-range breaking.
Environmental conditions of use
1, The altitude does not exceed 3000 meters.
2, Ambient temperature range:-40C~+45”.
3, Outdoor wind speed not exceeding 30m/s; and
4, Relative humidity: daily average is not greater than 95%, monthly average is not greater than 90%. 5、Installation location: installed in a place where there is no danger of fire, explosion, serious pollution, chemical corrosion.
and places of severe vibration.
6, the waveform of the supply voltage is approximately sinusoidal, three-phase supply voltage is approximately symmetrical
* More than the above normal use of environmental conditions, the user can be negotiated with the factory to solve the problem.
