Abstract

A camera system for gas-insulated switchgear systems, includes a front plate of the gas-insulated switchgear system having two front-plate connections, a central unit, and at least one camera in a camera housing or in respective camera housings. The line between the front-plate connections and the at least one camera is branched in the shape of a Y and the data communication and the current and voltage supply of the central unit occur via a common connection.

First claim

The invention claimed is:

1. A camera system for gas-insulated switchgear systems including a front plate of the gas-insulated switchgear system including two front plate connectors, a central unit, the camera system comprising:
at least one camera including a first camera; and
at least one camera housing, including at least one camera housing of the first camera, the at least one camera being housed in at least one camera housing, the at least one camera housing being conductive, being configured to enhance electromagnetic compatibility, and being conductively connectable to one component of the gas-insulated switchgear system, the at least one camera housing being strengthened via natural rubber seals or carbon-free rubber seals for use in at least one of SO2 and salt spray environments,
wherein the central unit is connectable to the first camera for data communication and including a Dynamic Host Configuration Protocol (DHCP) server and a captive portal,
wherein at least one camera housing of the central unit is accommodated in the at least one camera housing of the first camera,
wherein the central unit includes a power supply to supply current and voltage to the at least one camera, and wherein the power supply is suitable to supply the at least one camera with an input voltage to the at least one camera,
a shared connector, on an outer side of the camera housing of the first camera including the central unit, for a line for data communication between at least one of the two front plate connectors and the central unit of the first camera, and as a current supply and a voltage supply of the central unit of the first camera, the line running from the two front plate connectors to the shared connector of the first camera including a first side and a second side, wherein:
the line on the first side includes a plug, compatible with the shared connector, or a socket compatible with the shared connector,
line branches between the first side and the second side in a y-like manner into a first connecting line and a second connecting line on the second side such that
the first connecting line provides the current supply and the voltage supply to the central unit and is connectable to a first front plate connector of the front plate connectors, and
the second connecting line provides the data communication between a second front plate connector of the two front plate connectors and the central unit and is connectable to the second front plate connector, wherein the camera housing of the first camera includes at least one additional shared connector to connect at least one additional camera in an additional camera housing to the first camera, and to establish the data communication and the current supply and the voltage supply for the at least one additional camera via the at least one additional shared connector.

2. The camera system of claim 1 , wherein the first connecting line on the second side of the line has a USB plug or a USB socket.

3. The camera system of claim 2 , wherein the second connecting line on the second side of the line has an RJ45 plug or an RJ45 socket.

4. The camera system of claim 1 , wherein the second connecting line on the second side of the line has an RJ45 plug or an RJ45 socket.

5. The camera system of claim 1 , wherein the first camera is connectable to additional cameras in a series connection via the at least one additional shared connector.

6. The camera system of claim 5 , wherein the current supply and the voltage supply between the first camera and the additional cameras are carried out at a voltage of approximately 4 VDC.

7. The camera system of claim 6 , wherein the data communication and the current supply and the voltage supply between the first camera and additional cameras are carried out for each additional camera via an RJ45 patch cable having four wire pairs.

8. A gas-insulated switchgear system including the camera system of claim 6 .

9. The camera system of claim 5 , wherein, from the supply voltage in the at least one camera, 3.3 VDC is formed for supply of an optical sensor and a serializer, and 1.8 VDC is formed for supply of PWM-dimmable LED lighting.

10. The camera system of claim 9 , wherein a 4 VDC output voltage is provided for the at least one additional camera for the data communication and the current supply and the voltage supply of the first camera, via the at least one additional shared connector.

11. A gas-insulated switchgear system including the camera system of claim 5 .

12. The camera system of claim 1 , wherein the first camera is connectable to additional cameras via the at least one additional shared connector, wherein the additional cameras are connectable to the first camera in a parallel arrangement.

13. The camera system of claim 1 , wherein the shared connector is designed to be gas-tight or certified according to IP67, DIN 40050 Part 5.92.

14. A gas-insulated switchgear system including the camera system of claim 1 .

15. The camera system of claim 1 , wherein the captive portal is a captive portal redirect.

16. The camera system of claim 1 , wherein the input voltage is an input voltage from 4V to 17V.

17. The camera system of claim 1 , wherein at least one of the shared connector and the additional shared connector are designed to be gas-tight or certified according to IP67, DIN 40050 Part 5.92.

18. The camera system of claim 1 , wherein, from the supply voltage in the at least one camera, 3.3 VDC is formed for supply of an optical sensor and a serializer, and 1.8 VDC is formed for supply of PWM-dimmable LED lighting.

19. A gas-insulated switchgear system including the camera system of claim 1 .
