Appl. No.:

10/675099

Inventors:

David D. Brandt - Milwaukee WI, US
Jie Shen - Shanghai, CN
David L. Jensen - Barneveld WI, US

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

H02G 3/18

US Classification:

174 59, 174 50, 174 72 B, 174 88 B, 361600, 439620

Abstract:

Transmission of electrical signals can be conducted over a rail. The rail, which may be an at least partially open rail structure, may be disposed within an enclosure, and can be used to transmit data and power signals to an assembly of electrical components. A connector assembly may also be provided to facilitate the transmission of data and power signals between the components and the rail.

International Classification:

H01R 25/00

US Classification:

439638, 4399241

Abstract:

In one embodiment, the components within each respective unit of the MCC are connected powered by a connector assembly that is directly engaged to secondary power and network data conductors disposed of within the enclosure. The connector assembly, if so desired, will maintain connection even upon disengagement of the unit from the main power supply. This service position can be employed to provide a safe environment for diagnostic testing and repair of the unit. In another embodiment, the secondary power and network data conductors may by carried over an open rail system. This embodiment provides a convenient means of quickly and easily engaging the secondary power and network data conductors to the unit. Another embodiment provides a method for placing the unit into a service position.

H01R 27/02

US Classification:

324530, 324501, 439638, 361600

Abstract:

A system, in one embodiment, includes a power distribution center having an enclosure with an access door configured to move between a closed position and an open position. The power distribution center includes a non-contact sensor disposed inside the enclosure, wherein the non-contact sensor includes a non-contact voltage sensor, or a non-contact temperature sensor, or a combination thereof. The power distribution center also includes an indicator viewable outside of the enclosure while the door is in the closed position, wherein the indicator is coupled to the non-contact sensor.

International Classification:

H05K 5/02

US Classification:

361616

Abstract:

A system, in one embodiment, includes a power distribution center having an enclosure with an access door configured to move between a closed position and an open position. The system also includes a monitoring system configured to monitor operational parameters inside the enclosure. Also, the system includes an entry control system coupled to the monitoring system, wherein the entry control system is configured to lock the access door if the operation parameters are indicative of a potentially hazardous condition inside the enclosure.

Abstract:

A motor control center comprises a plurality of bays in which switchgear components, circuit protective components, automation components and power electronic components are disposed for driving motors and other loads. Network optical conductors are routed through one or more wireways adjacent to the bays. Distribution nodes are coupled to the conductors and are interconnected with respective network terminals within the bays. Components within individual bays for which EtherNet and/or Internet connectivity is desired are coupled to the network terminals. The conductors may comprise plastic optical fibers and may be designed to operate in the relatively high voltage environment of the motor control center bays.

US Classification:

700117000

Abstract:

A technique is provided or integrating system design, sales, and manufacturing functions. Systems including networked and programmable electrical components, such as motor control centers, and other electrical power control arrangements are designed, and a database is created for the design, including component and system designation data. The database may further include configuration information, settings, and so forth. The database is used as a tool in establishing a sales solicitation proposal from which sales of the system are offered. The same database is then used to program the various components of the system, such as through a temporary network link or via a permanent data network once the system is assembled.
