Library building - PS, EMO, Automation

Power supply

According to the degree of reliability of power supply, the library belongs to consumers of category II .

The design input load is 46 kW.

The annual electricity consumption of the library is 137 thousand kWh.

External power supply remains in place.

Electric power metering is provided in BRU.

Power electrical equipment

Power supply is provided from the manual control unit, which is installed in the electrical panel on the first floor.

Power receivers are electric receivers of process equipment and ventilation systems.

For power distribution in the project the power case of PR8513 series and the MZ series is used.

As the starting equipment of the P1 system, a magnetic starter of the PML series is used.

Backbone networks are made by WBGngLS cable open on brackets. Distribution networks are made by cables of VBGPngLS and VBGngLS, laid hidden under a layer of plaster. Control circuits of plenum system P1 are made by HVGhLS test cable.

Electric lighting

The project provides for working, repair and evacuation lighting.

Evacuation lighting fixtures are separated from the number of general lighting fixtures. For evacuation lighting, fluorescent lamps with built-in ES1 emergency power supply unit are provided.

The type of lighting fixture is provided depending on the purpose of the premises and environmental conditions.

Fluorescent and incandescent lamps are used as light sources.

For local lighting, a network of sockets is provided in the rooms.

As group lighting boards, MAB boards are adopted.

Lighting is controlled by switches in place and from boards.

Lighting distribution networks are made by VBGngLS cable laid in vinyl plastic pipe (riser) and behind suspended ceiling.

Group lighting networks are made by three-wire cable VBGngLS, laid hidden under plaster, behind the suspended ceiling, in corrugated vinyl-plastic pipes in the floor of the overlying floor and in the voids of floor slabs (extension).

Protective measures, potential equalization

As a protective measure against electric shock, grounding is adopted.

The project adopted the TNCS grounding system. In the supply, distribution and group network of power equipment and electrical lighting, the functions of zero working and zero protective conductors are separated (N and PE).

Zero protective conductor, metal pipes of utilities included in the building, metal parts of building structures are connected to the potential equalization system.

Connection of communication pipes and metal parts of building structures to the main grounding bus (GWB) is performed by HVG cable section. 25mm2 laid in the cable channel. The GWN is installed near the inlet switchgear in the electrical switchgear.

The internal potential equalization circuit is connected to the external ground circuit, which consists of 3 electrodes made of F16 mm steel with a length of 2.5m, connected by steel F14 mm with a WBG1x 25mm2 cable.

Automation

The project provides automatic protection of the heater from freezing of supply systems.

Automatic protection is carried out by a microprocessor meter-regulator of the TMZZSh4 type and temperature sensors of the DTS type.

The regulator is installed in a board with the assembly ShchMP1IR31 panel in a vetkamer and in the place.

The project also provides for the shutdown of ventilation in case of fire. Control equipment is installed in electrical panel.

All non-current-carrying parts of equipment that may be energized in case of insulation failure shall be grounded.

Fire alarm and fire alert.

This project was developed in accordance with the norms and regulatory and technical documents:

- NPB 882001 * "Fire fighting and alarm units. Design Codes and Regulations ";

- NPB 10403 "Warning and evacuation management systems in case of fire in buildings and structures";

- Rules of electrical installations devices (PUE);

- RD 7836.002-99 "Technical facilities of facilities safety systems. Symbols and schematic graphics of the system.

Fire alarm.

The project provides for the equipment of the library building with automatic fire alarm.

According to the degree of reliability of power supply, automatic fire alarm receivers belong to consumers of category I. As a receiving station, the Granit8 acceptance-control fire-protection device is adopted, with a built-in secondary power source, which is installed in the wardrobe on the 1st floor. The device is powered at ~ 220V from the input switchgear located in the electrical panel .

Distributing is carried out by VVGngLS3h2.5mm2 cable laid is hidden under a plaster coat.

In accordance with the feature of the controlled rooms, the project adopts IP2125M smoke sensors (DIP3M) installed on the ceiling of the protected rooms, as well as linear smoke sensors in the reading room

The design also provides for manual IPR fire detectors installed at the exits of the building, on staircases and in the halls. The height of the manual detectors installation is 1.5 m from the floor.

The fire alarm distribution networks are made by cable with copper cores of KSPV tank. 2x0.5mm and tank. 6x0.5mm, laid in the pipe (by riser), and also open on brackets.

Fire alarm loops shall be laid separately from all power and lighting networks. In case of parallel laying, the distance between fire alarm loops and power lines, lighting lines and process pipelines shall be at least 100mm.

Fire alert.

The fire warning project was executed in accordance with NPB 10403.

The designed building belongs to 2 types of fire warning systems.

Notification Methods:

-sonic - installation of "Prisma100" sound annunciators;

- light - "OUTPUT" light indicators taken into account in EO section are installed at outputs.

Fire warning distribution networks are performed by IWGngLS wire laid hidden under plaster layer.

Low-current devices.

Urban telephony.

The design provides for installation of junction box of KTP10 type. "Aquator" telephones are installed in the rooms.

Distribution networks of installation of telephones are carried out by mm TRP1h2h0.5 cable.
