control room
As a control room (English: electrical room) is a space designated in the electro-technical are housed devices, switchgear or protection systems. Examples are
- Switchgear for medium and low voltage ,
- Programmable logic controllers ,
- Distributors , devices for measurement and control technology ,
- Protection systems ( short circuit , overload , overvoltage protection ),
- or control centers such as the master clocks in clock systems.
Other side rooms are in the field of industrial production, as a control room called when they have to meet special requirements and rules, such as computer rooms , battery rooms, Prozessanalysengeräte- or in telecommunication rooms.
Main features
The location of these rooms is based on safety and traffic aspects, such as escape routes , good accessibility for operation and transport as well as fire fighting. Control rooms are provided separately from other production facilities (e.g. in the front building of a building), depending on local possibilities. These rooms are usually locked and are only accessible to specialist staff. Depending on the size and the surroundings, an additional escape exit is provided in a control room.
Depending on the type of equipment installed, switch rooms are designed taking into account impermissible heating from external and internal influences. Appropriate means for ventilation and cooling are provided. The rooms are fire-resistant and structurally separated from adjoining rooms. Depending on the environment, potentially explosive zones are taken into account by special devices such as locks or appropriately designed cable ducts.
The electrotechnical equipment is housed in control cabinets or open racks (so-called fields that define the location in the room). A cable floor (double floor) is provided in many control rooms. Cables can be fed into the control cabinets or fields from below with little effort.
Regulations
The features for the structural design of switch rooms are the subject of several DIN and VDI / VDE guidelines as well as ordinances. The guidelines VDI / VDE 3546 , DIN VDE 0100 , VDI / VDE 2180 as well as the workplace guidelines should be mentioned in particular . These standards are summarized and explained e.g. B. in NAMUR worksheet NA26 - PLT rooms control rooms, control rooms, utility rooms, planning aid for the structural design . The worksheet specifies the following essential requirements for control rooms (extract):
- Secure access and escape routes, also for the fire brigade .
- Location not below ground level (reason: danger from water in the event of pipe bursts and fire brigade operations, danger from heavy gases).
- Location outside the Ex zone.
- If possible, position within a building on the outer wall (cable feed).
- If necessary, several control rooms for the electrical power distribution can be assigned to the system parts in a meaningful way (decentralized control rooms close to the main consumer areas).
- Observe favorable cable routing, low-voltage and medium-voltage switch rooms should preferably be physically separated.
- Water, steam and product pipelines are not allowed to run through these rooms.
