Abstract
The invention relates to an electrical low-voltage switchgear, comprising at least two power units accommodated in slide-in units or in a housing, and comprising control units assigned to the power units. The control units are spatially separated from the power units and power levers and are connected to one another via signal lines.
Claims5
An electrical low-voltage switchgear assembly, comprising:
- a plurality of housings;
- a central data interface located in a first housing;
- a plurality of power units, each power unit being located in a second housing;
- and
- a plurality of control units, each control unit being associated with one of the power units and is configured to store up-to-date parameters and electrical data of the associated power unit,
- wherein each control unit is connected between one of the power units and the central data interface via signal lines, and the control units, the central data interface, and the power units are physically isolated from one another,
- wherein the power units and the control units are functionally independent of one another and are configured to be replaced independently of one another,
- wherein the control units are accommodated in a vertically running control area, which is located adjacent to a power section that includes the power units,
- wherein the control area is isolated from the power section by a vertical partition wall so that the control area is not influenced if damage occurs, and
- wherein the control area is protected against mechanical access by a separate cabinet door, which protects the control units from unauthorized access, and access to the control units is safely isolated from the power units.
