Abstract

A switching station for high or medium voltage offers a simple and practicable configuration for information transmission with a high security against failure. Panel devices are connected through a first bus line to a central control device. The panel devices feed a second bus line to which control devices of switching devices of the switch panel are connected. The second bus line is formed by an auxiliary line of the switching station.

Claims

1. A switching station for high or medium voltage, comprising:

a central control device;

a first bus line connected to said central control device;

first interfaces connected to said first bus line;

a given number of panel devices each connected to a respective one of said first interfaces;

second interfaces each connected to a respective one of said panel devices;

a panel-related second bus line formed by an auxiliary line and connected to a respective one of said second interfaces;

at least one of grounding and isolating switches having control devices connected to said panel-related second bus line; and

at least one power circuit breaker connected to a respective one of said panel devices.

2. The switching station according to claim 1, wherein said at least one power circuit breaker is connected through said second interface to said panel device.

3. The switching station according to claim 1, including a third interface connecting said at least one power circuit breaker to said panel device.

4. The switching station according to claim 3, wherein said third interface is a bus interface, and further participating devices are connected to said third interface.

5. The switching station according to claim 4, wherein said further participating devices are operating devices.

6. The switching station according to claim 4, wherein said further participating devices are protective devices.

7. The switching station according to claim 3, wherein said third interface has a higher data transmission rate than said second interface.

8. The switching station according to claim 1, wherein said control devices of said power circuit breakers each form one structural unit with a respective one of said panel devices.

9. The switching station according to claim 1, including switching fault protective devices associated with said panel devices.

10. The switching station according to claim 9, wherein said switch fault protective devices each form one structural unit with a respective one of said panel devices.
