US Patent:

20190391344, Dec 26, 2019

Filed:

Sep 3, 2019

Appl. No.:

16/558797

Inventors:

- Dublin, IE
Robert Judson Burns - Hendersonville NC, US
David Aaron Metcalf - Black Mountain NC, US

Assignee:

EATON INTELLIGENT POWER LIMITED - Dublin

International Classification:

G02B 6/38

Abstract:

An apparatus includes first and second components. A track supports one of the components for movement toward the other of the components. A first connector is mounted on the first component. The first connector retains an end portion of a first fiber optic cable, and has a first alignment portion. A second connector retains an end portion of a second fiber optic cable, and has a second alignment portion. The second alignment portion guides the second fiber optic cable radially into coaxial alignment with the first fiber optic cable upon movement of the first alignment portion against the second alignment portion. A floating mount device supports the second connector on the second component for guided movement radially relative to the second component upon movement of the first alignment portion against the second alignment portion.

- Dublin, IE
Dan E. Hrncir - Arden NC, US
David A. Metcalf - Black Mountain NC, US

International Classification:

H02H 9/04
H01H 33/53
H01T 2/02
H01T 4/12

Abstract:

An arc quenching device includes a frame, at least one controlled-arcing device supported by the frame, and at least one contact assembly supported by the frame and electrically connected to the at least one controlled-arcing device. The device further includes a racking mechanism supported by the frame and including a motor and at least one actuator member driven by the motor and configured to engage a feature in an electrical equipment unit compartment to move the arc quenching device within the compartment and engage the at least one contact assembly with a bus of the electrical equipment unit. The arc quenching device may be configured to be installed in a cassette in the electrical equipment unit and the actuator member may be configured to engage a feature of the cassette.

Inventors:

- Cleveland OH, US
Dan E. Hrncir - Arden NC, US
David A. Metcalf - Black Mountain NC, US

International Classification:

G01R 31/327
H01H 33/59

Abstract:

A test apparatus includes an output configured to be coupled to a sense input of an arc quenching device control circuit of an arc quenching system, a user interface, and a control circuit configured to generate a simulated sense signal at the output in response to an input at the user interface, the simulated sense signal representing a physical state associated with a fault condition of a bus coupled to the arc quenching system. The simulated sense signal may be configured to cause the arc quenching device control circuit to trigger an arc quenching device of the arc quenching system. The physical state may include, for example, a voltage condition, a current condition, a temperature, a pressure or a light intensity. In some embodiments, the simulated sense signal may include a current indicative of a current passing through a bus to which the arc quenching system is connected.
