Complete transformer substations for urban networks of through-passage and dead-end type - KTPG with a capacity of 100-2500 kVA, HV voltage of 6 or 10 kV and LV voltage of 0.4 kV are designed to receive, convert and distribute electrical energy of three-phase alternating current with a frequency of 50 Hz in systems with a dead-grounded neutral transformer on the low voltage side. KTPG are designed to supply power to agricultural consumers, individual settlements and small industrial facilities in areas with a temperate climate (from -45 ° C to + 40 ° C). Type of climatic modification U1 in accordance with GOST15150. Normal operation of the KTP is ensured under the following conditions: 1. Height above sea level - no more than 1000 m; 2.Environment - non-explosive, not containing conductive dust, corrosive gases and vapors in concentrations that reduce the parameters of the KTP in unacceptable limits; 3. Wind speed up to 36 m / s (wind pressure speed up to 800 Pa); 4. Type of atmosphere - II in accordance with GOST 15150. High-voltage input - air or cable, outgoing line branches - air or cable. Also, KTPG are manufactured as one-transformer and two-transformer (with sectioning for high and low voltage). Circuit breakers are installed on the LV side. Their number and rated current are shown in the table. The package of delivery of the KTP includes UVN (air inlet) and LVDN cabinets, a power transformer, an outdoor disconnector RLNDz-10/630 (on request). On request, the KTP can provide street lighting lines, which are switched on automatically by a signal from the built-in relay and by installations for reactive power compensation. ...
