Shop Electrical Design

This project is developed on the basis of related sections and in accordance with regulatory documents: PUE 6 ed., GOST 30331, TKP454.04-149-2009, TKP 452.04-153-2009.

Board with mounting panel of hinged version is adopted as input distributing device.

For connection of power electrical equipment, the design provides a switchboard (SB on the plan) of the modular type.

The lighting panel is of modular type and is installed in the electrical panel (CB on the plan). The boards are equipped with a load switch at the input and circuit breakers on the outgoing lines, on the outgoing line on outdoor lighting and advertising there is provision for installation of a diaper. automatic and astronomical time relay.

Distribution and group power and lighting networks are designed taking into account the characteristics of the environment, the room finish list.

The normalized lighting of the premises is adopted in accordance with TKP 452.04-153-2009, depending on the technological purpose of the premises, the characteristics of the medium and the normalized lighting. Light sources are luminaires with fluorescent lamps equipped with EPRA.

The design provides for working, duty, emergency (evacuation and safety lighting) for 220V.

Lighting calculation is performed using the program DIALux. Number of lighting fixtures and their arrangement in rooms is made taking into account normalized illumination on working surfaces, non-uniformity of illumination and coefficient of discomfort.

Installation height above the level of the clean floor: switches in the rooms 1.0m; sockets 1.0m.

Lighting network is designed by WBGngLS cable.

Cross sections of wires (cables) of group lines are taken equal to 1.5 mm2.

Lighting control is carried out by switches of hidden installation in place. Control switches for illumination of wet and fire hazardous rooms are placed in adjacent rooms.

The commercial accounting is carried out on the three-phase multitariff electronic counter of live broadcast SE301VU R33 146 JAZ 220/380B 100A of C. t.1.0, established on I LIE.

in accordance with GOST 30331... "Electrical installations of buildings" as protective safety measures in the designed building are used:

-TN -C-S bushing system with separation of conductor PEN function into operating and protective,

- automatic disconnection using devices responding to differential current and combined with the device for protection against overcurrent - RCD;

- ground R < 30 Ohm (natural grounding conductor - steel structures of the building),

- double insulation (Class II lamps),

-the main potential equalization system combining pipelines and air ducts at the entrance to the building,

- additional potential equalization system combining the FH (shower tray housings and towel dryer), the FH and the conductor of the additional potential equalization system (HO5VVF), laid from the PE bus of the VRU to the shower tray. An additional equalization system is provided in the washing, electrical panel, ventilation chamber, ITP with a steel strip of 25x4mm around the perimeter of the premises.

Connect all metal parts of the building to each other and connect to the grounding conductor.

The building has IV degree of fire resistance according to SNB 2.02.0198 and does not require lightning protection.

All electrical installation works shall be carried out in accordance with the effective PUE85 and SNiP3.05.0685.
