Abstract

A switchgear installation has a cubicle with a door to provide access thereinto, and a low voltage air circuit breaker is mounted therein and accessible through the door. Coupled to the circuit breaker is a logic module, and a portable user interface module is releasably mounted on the exterior of the door and operatively connected to the logic module to display information concerning the operation of the breaker and to provide an interface for the user to interact with the logic module and thereby with the breaker.

Claims

1. A switchgear installation comprising:

(a) a cubicle having a door to provide access thereinto;

(b) a low voltage air circuit breaker mounted therein and accessible through said door;

(c) a logic module coupled to said circuit breaker and operatively connected to various components of said breaker to enable adjustment and reporting of its operation; and

(d) a portable user interface module releasably mounted on the exterior of said door and operatively connected to said logic module when so mounted, said interface module displaying information concerning the operation of the breaker and providing an interface for the user to interact with said logic module and thereby with said breaker.

2. The switchgear installation in accordance with claim 1 wherein said portable user interface module includes a battery for providing the necessary power for operation of said logic module and said portable user interface module.

3. The switchgear installation in accordance with claim 1 wherein said door provides a mounting into which said portable user interface module may be readily inserted or removed therefrom.

4. The switchgear installation in accordance with claim 1 wherein said switchgear installation includes at least one cable from said logic module to said portable user interface module.

5. The switchgear installation in accordance with claim 1 wherein said cable extends to said mounting on said door.

6. The switchgear installation in accordance with claim 1 wherein said portable user interface module may be nested on said logic module and is readily removable therefrom.

7. The switchgear installation in accordance with claim 1 wherein said portable user interface module enables setting up, monitoring, querying functions for said breaker.

8. The switchgear installation in accordance with claim 1 wherein said door mounting includes a connector to which said user interface module may be coupled.

9. The switchgear installation in accordance with claim 1 wherein said portable user module interface includes a battery for providing the necessary power for operation of said logic module and said portable user interface module, said door providing a mounting into which said portable user interface module may be readily inserted or removed therefrom, said installation including at least one cable from said logic module to said portable user interface module, said portable user interface module enabling setting up, monitoring, and querying functions for said breaker.

10. The switchgear installation in accordance with claim 9 wherein said door mounting includes a connector to which said user interface module may be coupled.

11. The switchgear installation in accordance with claim 1 wherein there are multiple cubicles, breakers and logic modules, said user interface module being mountable on the doors at each of said cubicles to interface with the logic module and breaker in each of said cubicles.
