5.1 Power supply system

5.1.1 This project is performed on the basis of the Customer's assignment and in accordance with the requirements of the following regulatory documents:

Decree of the Government of the Russian Federation of 16.02.2008 No. 87 "On the composition of sections of design documentation and requirements for their content" (as amended on December 21, 2009);

SNiP 230595 * "Natural and artificial lighting";

SanPiN 2.2.1/2.1.1.127803 "Hygienic requirements for natural, artificial and combined lighting of residential and public buildings";

GOST 21.11012009 "Basic Requirements for Design and Detailed Design Documentation";

SP 311102003 "Design and installation of electrical installations of residential and public buildings";

SNiP 3.05.0685 "Electrical devices";

SP 6.13130.2013 "Fire protection systems. Electrical equipment. Fire safety requirements ";

GOST R 50571.5.522011 Electrical Equipment Selection and Installation;

Electrical Installation Rules (PUE).

5.1.2 Power supply of the facility is provided from KTPN 6/0.4 kV.

5.1.3 As per PUE power supply reliability of electric receivers refer to:

- category I - communication, automation and dispatching equipment, emergency lighting, smoke removal system, gas boiler room equipment;

- to category II - other electric receivers.

Power supply of the structure is carried out via two independent mutually redundant cable lines at voltage ~ 380/220V, 50 Hz with de-grounded neutral, AC TNCS power distribution and grounding system with separation of zero working and protective conductors at BRU-B input .

By the nature of electrical loads, the structures do not have distorting factors for electrical power quality indicators (PCE) according to the classification GOST 1310997 "Electricity quality standards in general-purpose power supply systems."

Reactive power compensation is not required.

5.1.4 For reception, account and power distribution the vvodnoraspredelitelny VRU3SM1320 UHL4 device installed in switchboard is provided.

Power supply of electric receivers of the first category (communication, automation and dispatching equipment, emergency lighting, smoke removal system) is carried out from the CAS panel, connected through a box with an automatic reserve switching-on device (JAVP3).

Electricity is accounted for by electronic three-phase counters.

m of active and reactive energy of transformer actuation of accuracy class 1.0 of Mercury 230 ART03 type at VRV inputs, and direct actuation of Mercury 230 ART01 at IAVR.

Schematic single line diagrams of distribution networks of a construction are provided on sheets 4 ÷ 19 IOS1 .

5.1.5 Determination of the design capacity as a whole for the structure is performed in accordance with the calculation procedure SP311102003. Information about electrical receivers of the structure, their installed and design power are given on sheets 1-3 of IOS1.

5.1.6 Connection of power electrical equipment is performed at voltage 380/220V, 50 Hz from distribution boards, which are installed in the electrical board, corridor, security rooms and gas boiler room. Control of electrical equipment is provided through complete devices and through start-up devices installed on site.

Disconnection of ventilation systems and air conditioning in case of fire is carried out by removing supply voltage from the bus bars of the distribution board through an electromagnetic contactor .

- the main and additional potential equalization system with the device of the integrated grounding device (RAM). At the entrance to the building, three electrodes with a diameter of 18mm are clogged, which are connected to the outer ground circuit made of strip steel with a section of 5x50mm;

- for the system of additional potential equalization, it is provided to connect to each other, located at a distance of less than 2.5 m, all open conductive parts, including metal parts of building structures, simultaneously accessible by touch.

- protection against direct lightning strikes in accordance with GSP 220207 using a lightning screen of round galvanized steel with a diameter of

8 mm, grid cell spacing is not more than 6x6 m. Current leads from lightning screen are made of round galvanized steel with diameter of 8mm with distance not more than

25m, join RAM. Diagram of potential equalization system is given on IOS1 sheet 20.

5.1.11 Luminaires with luminescent lamps are the main light source for all rooms. The illumination of the premises, the type of lighting fixtures and their number are shown on the plans, on sheets 2125 IOS1.

Emergency lighting is provided by highlighting part of the lighting fixtures of the working lighting. Emergency lighting fixtures have a sign that distinguishes them from working lighting fixtures. Control of light fixtures - switches in place.

5.1.13 All types of distribution and group networks to electric receivers of category II are made by cable of VBGngLS grade, to electric receivers of category I - by cable of VBGngFRLS of design sections with selection of laying method according to GOST R50571.522011 and PUE of the seventh edition.

Cables shall be laid as follows:

- in flexible corrugated pipes from IPA;

-in trays;

-in the bars of brick walls

-in cable channels.

Group lines for power current collectors are made with additional protective PE-conductor. The distribution network from trunk boards to group boards is five-wire (3L + N + PE).
