Principles of busbar trunking planning

2/8 Siemens LV 70 · 2008

■ Overview

Trunking units for currents from 40 to 6300 A

When it comes to developing a power distribution concept, including the configuring of systems and components, it is necessary to coordinate the requirements and possibilities of the end-user with those of the manufacturer.

With this in mind, the individual systems are described along with their technical features and applications. Another element is the graphic representation of the various busbar trunking elements. All details of importance for the planning work are specially emphasized and explained.

In "Information on engineering" in the chapters 3 to 5, you will find ideas for ready-to-use planning solutions. For example, dimen-sioning principles are presented and in-depth information given on subjects such as system design, short-circuit protection, fire barriers or functional endurance.

Services and engineering tools are available from Siemens to simplify the drawing up of customer specifications.

General information

When developing the planning concept of a power supply system it is necessary not only to consider the standards and specifications in force but also to clarify the correlations between economy and technology. Electrical equipment such as distribution boards and transformers must be dimensioned and selected so that they represent an optimum in their entirety and not just individually.

All components must be sufficiently dimensioned for the loads which arise in the event of a fault as well as during operation at rated values. Other decisive points to be considered when drawing up the power concept are:• The type, utilization and shape of building

(e.g. high-rise, flat-roof and number of storeys)• Determination of load centers and fixing of possible supply

routes and locations for transformers and main distribution boards

• Fixing of building-related rating values according to specific area loads depending on the building's use

• Specifications and requirements imposed by the building authorities

• Requirements imposed by the power supply companies

The result will never be a single solution but several versions which must be assessed with regard to their technical and economic implications. The following requirements are paramount in this connection:• Easy and clear-cut planning• Long endurance• High availability• Low fire load• Flexible adaptation to alterations in the building

In most applications these requirements are easily met by the use of suitable busbar trunking. For this reason, busbar trunking rather than the cable installation method is being used more and more often by engineering offices for the conveyance and distri-bution of power. Siemens offers busbar trunking from 25 to 6300 A:• The CD-K busbar system from 25 to 40 A for supplying power

to lights and miniature loads• The BD01 busbar system from 40 to 160 A for supplying

power to workshops with tap-off points up to 63 A• The BD2 system from 160 to 1250 A for supplying power to

medium-size loads in buildings and in industry • The LD system for supplying power to loads with medium

power consumption and in industry• The LX sandwich system for the conveyance of large amounts

of power in buildings• The LR encapsulated system for the conveyance of power in

extreme ambient conditions (IP68)

Advantages of the system solution during operation:• Transparency of switching states• Central recording of power costs• Increase in plant availability as a result of immediate detection

of the type of fault and its location• Preventive maintenance through recording of operating hours

and operating cycles

System concept of communication-capable busbar trunking

Switching and reporting with the BD2 system

The standardized tap-off units of the busbar trunking systems can be combined with standard types of device unit to form a system solution of communication-capable busbar trunking.

The standard applications are assembled at the factory from a combination of tap-off unit and ancillary equipment unit. The bus cable for transmitting the data signals is laid in a cable duct which must be mounted on the busbar enclosure.

■ Application

Standard application: lighting control

The lighting control application enables the efficient and low-cost implementation of lighting control systems for large areas such as are used, for example, in supermarkets, furniture stores or DIY centers.

The power bus is formed by BD01 or BD2 busbar trunking from Siemens, depending on the current requirement.

The standard tap-off units are equipped with miniature circuit breakers or fuses feed CD-K busbar systems which act simultaneously as the support system for the lighting elements. The economical and efficient control of extensive lighting systems is thus possible.

The EIB (European Installation Bus) or AS-Interface bus systems are suitable for standard applications. On live busbar systems the tap-off point for power and bus can be adapted to the operational requirements.

Possible functions of the lighting control• Three times single-pole switching (L1, L2, L3) or 1/3, 2/3, 3/3

control• Feedback of switching states• Lamp test• Recording of operating hours and operating cycles

Standard application for consumption recording

The consumption recording function enables the central recording of distributed power meters.

The time-consuming reading of local meters is no longer necessary. Integration of the consumption recording in a visualization or I&C system by means of the data bus creates maximum transparency in the power distribution board. If recorded continuously, the measured values collected can be assigned to cost centers at a central point. The evaluation of trends and histories enables the data acquired to be analyzed.

The combinations of tap-off unit and ancillary equipment unit can be equipped with either calibrated or non-calibrated power meters and enable the quick and transparent presentation of power consumption levels at the power tap-off points.

The power bus is formed by BD2, LD or LX busbar trunking from Siemens, depending on the current requirement. Transformer sets (non-calibrated and calibrated) are available for the various tap-off units and levels of current.

Possible functions for consumption recording• Recording of consumption data• Resetting of meter total• Indication of a group fault• Reporting in the event of meter overflow, calling up of

historical data

Standard application for switching and reporting

The application for switching and reporting enables the remote switching and remote monitoring of tap-off points for power sup-ply or motors feeders.

The power supply becomes highly transparent through the central recording of switching and operating states. In the event of a fault, the type of fault, e.g. short-circuit or overload tripping, and its location are detected quickly and efficiently so that the availability of the power supply system is effectively increased.

The power bus is formed by BD2, LD or LX busbar trunking systems from Siemens, depending on the current requirement. The combinations of standard tap-off unit and standard device unit are equipped with corresponding switching devices and enable the centrally controlled switching and monitoring of the circuit breakers.

The AS-Interface or PROFIBUS bus systems are suitable for standard applications.

Possible functions for switching and reporting • Central recording of switching and operating states• Local and central switching• Switching on is monitored by means of an integrated run-time

monitor• Fault signal inputs• Group fault signal• Short-circuit signal• Overload signal• Recording of operating hours and operating cycles• Limit value signals

■ Overview

Easier when it comes to planning

Easy to plan, quick to install and flexible to use: Siemens busbar trunking systems are the economical answer for conveying power into any building. The power distribution system can be precisely planned from the total load rating and the type and number of loads. Clarity is assured by the line-shaped network topology with regularly arranged load feeders. All applications can be implemented in less time and space with standardized sizes.

Quicker when it comes to installing

Benefits during installation: Busbar trunking systems can be installed by two persons, saving time and money compared to the costly cable installation method. Installation errors are practically ruled out by the safe and user-guided connection technology. No special tools are required. Another benefit for quick installation: Siemens busbar trunking systems are easy to fasten and have large intervals between supports (busbars up to 4 m, cables every 1.5 m).

Siemens busbar trunking systems are an economical alternative to the cable installation method.

With cable installation, new loads are connected by way of an additional sub-distribution board, which is costly and time-consuming

Tap-off units near the loads make local arrangements more transparent

High short-circuit strength and minimum fire load result in greater safety

A step-ahead in terms of safety – be it short-circuit strength or fire load. For example, the BD2A-250 busbar trunking systems have a fire load of only 1.32 kWh/m; comparable cables (NYY 4 × 95/50 mm2) have 5.19 kWh/m by contrast. And the busbars are halogen-free. Siemens busbar trunking systems have a high short-circuit strength. Also, the near-load protection against short-circuiting simplifies troubleshooting.

High fire load with cables

Low fire load with busbar trunking

More flexible in case of expansions and modifications

If the power distribution system has to be adapted to new requirements, the busbar will take you quicker to your goal.

For example, new tap-off units can simply be mounted on the tap-off points. The system can be expanded and modified with-out difficulty. Tap-off units and system parts increase the flexibil-ity. Cost-intensive downtimes are eliminated or minimized. The power distribution system enables faultless operation with high user-friendliness and safety.
