Distribution board
|
The distribution board is the central interface between the structures in the building model and the electrical diagram.
The function has a number of levels and the at the same time, it is: External properties (housing) and parameters for installation in the building model. Content of the distribution board, electric circuit and equipment. Agreed-upon information appears in the cells. You can configure the display for each column. Structure of the electrical diagram. The database is evaluated graphically as a circuit diagram, in lists and reports. The function is only available in models with a code number between 500 and 899. Important!

A distribution board is a complex functional unit and must first be created. Afterwards, you can insert it into the model as an object.
Configure distribution board
You develop the internal structure by filling the distribution board with electric circuits, using
Moreover, frequent changes are necessary: You insert new electric circuits, delete those that are unneeded and move the existing ones. In addition, you modify individual electric circuits by inserting new components and changing or deleting existing ones.
In the description, we assume that the distribution board exists, is open and the Circuit List tab is active.

Main and sub distribution boards

High voltage systems usually consist of several levels with main and sub distribution boards. When the structure is configured correctly, DDS‑CAD calculates the |
- Begin each distribution board with a supply. (
Relevant circuit layouts ) - Be sure to use realistic parameters when configuring the final circuits. This ensures selection of properly dimensioned equipment and correct calculation of the power consumption.
- Ensure that the current loading is as symmetrical as possible. Unsymmetrical loading often results after modifications because single phase circuits are not distributed uniformly across the line conductors. ( Create symmetrical current loading)
- In the main distribution board, define special electric circuits for supply of the sub distribution boards. ( Relevant circuit layouts)
- Assign each sub distribution board to its own supply circuit in the main distribution board. ( Link sub distribution board with main distribution board)
Subordinate bus bar (Level 2)

Often, several final circuits are grouped on a subordinate bus bar. In DDS‑CAD, create a subordinate bus bar as electric circuit Level 2 ( |

We use the term low voltage system to refer to several types of systems:

Reorganize distribution board
Changes in the distribution board cause subordination in the numbering and generate an unsymmetrical current loading. Suitable operations can be used to arrange the numbers and designations, optimize the current loading and correct the dimensioning. In the description, we assume that the distribution board exists, is open and the Circuit List tab is active.
You can block changes of the name or number of circuits or components. This prevents undesired changes for these circuits due to a reorganization.
