Abstract
Switching operations in a switchgear assembly, in particular a medium-voltage switchgear assembly, are carried out via a control apparatus. The control apparatus has an electronic memory card for variable storage of control data which automatically initiate the switching operation or each switching operation. The control process then takes place exclusively via the memory card. The memory card is inserted into a card reader in the switchgear assembly. After this, an automatic sequence of the desired switching operations takes place using a switching program stored in advance in the memory card.
Claims8
In combination with a high-voltage or medium-voltage switchgear assembly having a plurality of controlled devices selected from the group consisting of a power breaker, a switch disconnector, and a grounding switch disposed in a switch panel of the assembly, a control apparatus for controlling the controlled devices, comprising:
- an electronic memory card having stored thereon operating authorization for the switchgear assembly and to store system control information defining a switching program with a plurality of control data items representing a sequence of switching operations;
- the control data items automatically producing control signals for initiating at least one switching operation within the switch panel for at least one of the controlled devices.
An improved control apparatus for controlling a system device via a memory card having control information and system control information stored thereon, and to cause an enable signal and a control signal to be produced for the device, the improvement which comprises:
- the system being a high-voltage or medium-voltage switchgear assembly having, if necessary, further devices;
- the system devices being a plurality of devices selected from the group consisting of power breaker, switch disconnector, and grounding switch arranged in a switch panel in the system;
- the memory card being electronic memory card;
- the control information stored on the memory card representing operating authorization;
- the system control information stored on the memory card forming a switching program with a plurality of control data items representing a sequence of switching operations;
- and wherein
- control signals for initiating at least one switching operation in the switch panel are automatically producible for at least one device using the control data.
