International Classification:

H01H 27/06

US Classification:

200 4308, 200 4304

Abstract:

An arrangement is provided for the overall handling of removable controls for an electrical device including the installation and removal of controls from a base or other housing portion of the overall device, e. g. an overhead switch utilized in electrical power distribution/transmission. The arrangement includes facilities for selectively securing or releasing the controls with respect to cooperating housing portions of the device. An operating member is provided with provisions for cooperating with the controls for securing and releasing the control with respect to the operating member. In a preferred arrangement, the controls have separate control functions.

International Classification:

H01F 7/08

US Classification:

335229000

Abstract:

An electromagnetic actuator is capable of providing a high speed driving force, for example, for driving the contacts of a circuit breaker or similar power distribution equipment. The electromagnetic actuator may use a directly powered moving coil element in combination with one or more energized stationary coils to generate an output force using reduced requirements for current, voltage and current/voltage rate-of-change. Precise control of actuator motion is obtained by permitting different supply voltages, firing times and capacitor supplies. The electromagnetic actuator may further incorporate a return spring arrangement and a magnetic latch arrangement.

David M. Evans - Palatine IL
Joel A. Ramos - Chicago IL

Assignee:

S & C Electric Company - Chicago IL

International Classification:

H01H 3302

US Classification:

200144R

Abstract:

A high voltage circuit interrupter is enclosed within an integral insulating housing that includes an operating mechanism enclosing portion, an insulator portion, and a muffler portion. The integrally formed insulating housing is formed to provide a groove in one interior wall of the operating mechanism enclosing portion and a similar groove is formed on the housing cover immediately opposite the groove in the wall so that a portion of the operating mechanism can ride in the grooves thereby eliminating certain internal metallic components. The operating shaft of the interrupter is hexagonal in cross section thereby eliminating the need for special machining, keys, and cross pins to attach operating levers to the shaft. Operating triggers having round bearing surfaces are inserted over the ends of the hexagonal shaft to provide a smooth running bearing fit with openings in the housing wall. A unique locking arrangement is utilized to lock the lever arm of the operating mechanism to the hexagonal shaft.

Assignee:

S&C Electric Company - Chicago IL

International Classification:

H01H 2500

US Classification:

200335

Abstract:

A manual operating handle assembly for an enclosed switch includes a walled frame which resides within the switch enclosure and rotatably mounts a shaft. A sprocket on the shaft turns therewith to move a chain coupled to another sprocket which operates the switch or a stored-energy operator therefor. A pair of arms keyed to the shaft mounts a handle for longitudinal sliding movement toward the shaft and into the frame, and away from the shaft and out of the frame. Rotation of the handle between extreme rotative locations rotates the arms and the shaft. A contoured surface within the frame interferes with the handle in its extreme rotative locations when it is within the frame to prevent rotation thereof. Only if the handle is first slid out of the frame does it clear the surface for rotation between its extreme rotative locations. When the handle is between its extreme rotative locations, it cannot be slid into the frame due to interference of the contoured surface.

S&C Electric Company - Chicago IL

International Classification:

H01H 300

US Classification:

200153SC

Abstract:

A linear operating mechanism is provided for operating one or more electrical switches or interrupters, the mechanism selectively closing the switch via movement of a switch operating member and immediately thereafter being capable of opening the switch as required. The operating mechanism includes a carriage that is movable over a linear path to charge an opening spring and a closing spring. The switch operating member is movable along an axis parallel to or coincident with the path of the carriage. The opening spring and the closing springs are disposed about a common axis parallel to the movement of the carriage and the switch operating member. A first latch arrangement is provided for preventing switch-closing movement of the switch operating member when the switch is open and the first latch arrangement is engaged. A second latch arrangement is provided for preventing movement of the carriage opposite to the direction of charging movement after the springs are charged and when the second latch arrangement is engaged. The latch arrangements each include a gapped, latch ring that cooperates with a latch member that is received within the gap of the latch ring.

International Classification:

H01H 3100

US Classification:

307130

Abstract:

A multi-pole group-operated switch configuration is provided for electrical distribution circuits. The switch configuration includes integral arrangements for sensing circuit parameters and supplying power for a switch operator of the switch configuration. The switch configuration includes a plurality of switch-pole units. In accordance with desired characteristics and features, one or more of the switch-pole units includes an integral current-sensing device, an integral voltage-sensing device, or an integral combination voltage and current-sensing device. The voltage-sensing device also provides operating power to power a switch operator and charge the batteries of the switch configuration.
