Complete transformer substations in concrete case
Complete one - and two-transformer substation (MITS and (2) MITS) in a concrete housing serve for the reception, conversion and распределенияэлектрической energy efficiency (EE) of three-phase AC voltage of 6-20 kV, 50 Hz and are designed for use in sistemahelektrosnabzheniya urban housing and public utilities, public and industrial facilities, as well as zones of individual buildings and kottedzhnyhposelkov. EE distribution is carried out on voltage of 0.4 kV using the waste from BKTP cable lines. Substation type (2) BKTPkomplektuetsya dvuhobmotochnye "oil" transformers (or "dry" option) with capacity from 25 to 2500 kVA.
At the request of the Customer (2) BKTP can be equipped with an automatic backup switching (ATS) on the low voltage (LV) or on the side of the high-voltage (HV).
In addition, on the HV side is possible to connect the power cable cross sections up to 240 mm2 inclusive.
Characteristic features of our (2) BKTP are:
· The possibility of developing individual solutions (equipment) for each object;
· The use of modern, reliable and safe operation of electrical equipment (see. Paragraph 1.3);
· Pre-installation testing and commissioning of electrical equipment in the factory;
· Relatively small size (cm. 1.4);
· High structural strength;
· Simplicity of design and ease of installation at the site.
in terms of the impact of climatic factors of the environment in accordance with GOST 15150 and GOST 15543.1 related to climatic design UHL category 1 and operated under the following conditions:
ambient temperature from -40 ° C to +40 ° C;
relative humidity up to 100% (without loss of frost and dew);
height above sea level of 1000 m,;
Environment explosive, not containing conductive dust, corrosive gases and vapors at concentrations that deplete the materials and insulation;
Scene types I, II.
