Distribution panels are made of individual manufacture and mounted design with a disconnecting device at the input and group single-phase and three-phase automatic machines with a 3L+N+PE bus system. The group lighting network is carried out by a VVG cable with a cross-section of 3*1.5mm2. Control of emergency lighting by a single-pole automatic device provided as an emergency lighting panel of the Central Administrative District. Power electrical equipment Switch cabinets with group three-phase and single-phase automatic machines are provided for connecting technological equipment in the relay, hardware and communication rooms. Connection of technological equipment is performed by specialists of the STB. The outlet network is made by a cable with copper cores with a cross-section of 3x2. 5 mm2 in a corrugated pipe in fines. External power supply The power supply of the STB building is provided from a 40 kVA transformer substation of the KTPN 10/0. 4 kV type, which is connected by a 10 kV cable line to the existing 10 kV opora No. 32 overhead line. KL-10 kV is provided by a 10 kV ASBG cable in a trench at a depth of 0.7 m. On the support No. 32, a linear disconnector RLND 10 is installed, a valve arrester RVN-10 and a cable mast coupling. The railway crossing is made by the puncture method. Transformer substation adopted KTPN type with 10 kV cable entry and 0.4 kV cable outputs. For backup power supply to consumers of the first category, an automated diesel power plant with a capacity of 25 kVA is provided. 11.3. Electric lighting of the empty car parking lot Electric lighting Electric lighting of the 15-track empty car park at the 441 km siding is carried out from a 100 kVA KTP with a 3L+N+PE connection scheme in accordance with the technical conditions for electric lighting. Electricity distribution is carried out from the KTP-0,4 kV via a cable line to the switchgear RU-0,4 kV. Electric lighting of the empty car park consisting of 15 tracks at the 441 km siding is carried out from the lighting control box. Lighting is made by searchlights of the PKN-1000 type with DRL-220-500-5 W lamps designed for lighting construction sites. Searchlights are installed on searchlight masts along the perimeter of the empty car parking lot. At the floodlight masts,a cable (VVGng3x2. 5+1x1. 5) is laid to the floodlights in a corrugated pipe. жүктеу/скачать 239,65 Kb. Достарыңызбен бөлісу:
