1. The project was completed on the basis of the technical specifications and in accordance with the requirements of SNiP 23-05-95, SP31-110-2003, PUE, GOST R50571.
2. The technical solutions adopted in this set of working drawings comply with the requirements of environmental, sanitary and hygienic, fire prevention and other standards in force in the Russian Federation, and ensure the safe operation of the facility while observing the measures provided for by the working drawings.
3. Power supply of the 3ShR distribution cabinet is provided from the designed KTPN of 1x400 kVA 10 / 0.4 kV. The distribution cabinet is installed in the electrical panel ABK. Electricity metering is carried out in RU-0.4 kV KTPN 1x400 kVA. Back-up power supply is provided from a diesel generator set.
4. The project provides for working and evacuation lighting ~ 220V, repair lighting ~ 36V. Lamps with fluorescent lamps are used as light sources. Types of fixtures correspond to the categories of premises and are indicated on the plan. The project provides light indicators "Exit" with built-in batteries. As evacuation taken lamps with built-in batteries.
5. The electrical wiring is made with a cable VVGNG, laid in a PVC box, PVC pipes on the walls and ceiling.
6. The voltage drop on the lamps does not exceed 2.5 %%%.
7. Grounding electrical equipment made with the help of zero protective conductors.
8. The project provides for the shutdown of ventilation in case of fire.
PROJECT DOCUMENTATION OF ELECTRICAL POWER SUPPLY
9. The color of the cables to perform in accordance with the EIR p.2.1.
10. The project provides for the following measures of protection against direct and indirect contact: - shells of electrical equipment IP31, IP54, IP65; - automatic power off; - protective grounding, - protective cutout device, - double insulation, - ultra low voltage.
11. The project tested the operation of circuit breakers at short-circuit currents in accordance with the requirements of the ПУЭ item 1.7.79.
12. Near the building there is a re-grounding circuit of the neutral wire from a steel strip of 5x40 mm and vertical electrodes from a corner of steel 63x63x6 mm L = 3 m, Rc <10 Ohm.
13. Lightning protection of the building, see project 500.2-EG.
1. Potential equalization scheme for 1ShR, 2ShR, YR cabinets, see 500.2-07-EOM.
2. In rooms N3,12,14, perform an additional potential equalization system. To the additional potential equalization system, connect all open conductive parts of stationary electrical installations that are accessible to touch, third-party conductive parts (including those that go outside the room). An additional potential equalization system is performed with wire ПV1 1х4 mmЕ. In these rooms, install additional potential equalization bushes (HVAC), to which wire PV1 is connected. Metal inserts on pipelines for cold and hot water supply, metal sinks are connected to SHDUP with wire PV1 1x4 mm. Pallets in non-metallic showers.
