Dual installation for ventilation and extinction gas and smoke exhaustion
The application consists of power plant, automation system and light currents, afferent to the ventilation and gas exhaustion installations.
As design basis were:
- architectural plans
- design themes made by other specialties
- beneficiary requests
- rules and regulations in force for design, construction and operation of wire plant.
Main consumers of electricity are:
- Extraction fans and input air fans;
- non-return gas valves;
- fire detection and extinguishing units;
- Power panels and automation panels for fans & gas valves control.
Electricity supply of gas exhaustion installation will be achieved prior to the general switch of the transformer station of the building, and from the backup source provided by existing electric generator. The generator is connected in buffer through AAR which enters into service if the power supply is no longer in service.
Primary power& automation panel – for gas exhaustion installation (TD1) – is located in the basement of the building, in room named “ANEXA”, alongside the existing electric panel for vital circuits (TCV), the panel basement common areas (TSSC) and the panel shutter supply (TVL) of the existing ventilation installation of the building.
A metering on low voltage of the new installation of ventilation and gas exhaustion.
Metering on low voltage is achieved in electric panel TD1 located in the basement of the building.
The second power & automation panel for gas exhaustion installation (TD2) is located on level 3 of the building, in “CAMERA TEHNICA” and will be fed from TD1 (from the building basement).
The circuit’s power TD2 will be done on existing routes and then on a new route.
Electric branch is underground, from transformer post to power and automation panel (TD1) located in the basement, on existing routes.
