46907807, Sep 1, 1987

Filed:

Jul 1, 1986

Appl. No.:

6/880867

Inventors:

Leonard V. Chabala - Maywood IL
John Haarsma - Barrington IL
Raymond P. O'Leary - Evanston IL

Thomas J. Tobin - Northbrook IL

Assignee:

S&C Electric Company - Chicago IL

International Classification:

H01B 320

US Classification:

252572

Abstract:

An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.

Joel A. Ramos - Chicago IL
Leonard V. Chabala - Maywood IL
Peter J. Meyer - Chicago IL
Thomas J. Tobin - Northbrook IL

Assignee:

S&C Electric Company - Chicago IL

International Classification:

H01B 1716

US Classification:

174161R

Abstract:

A durable polymeric bearing is provided for a rotatable support insulator. The bearing is of sufficient conductivity to permit the flow of leakage current and capacitive charging current through the bearing. Thus, tracking across and/or deterioration of the bearing is avoided since insufficient voltage is developed across the bearing to cause any deleterious effects.

Assignee:

S&C Electric Company - Chicago IL

International Classification:

H01H 3302

US Classification:

200146R

Abstract:

A multi-pole group-operated switch is provided for electrical power distribution circuits. The switch is self-contained and suited for ease of use with various line spacings and arrangements of the distribution lines; e. g. , side-by-side (horizontal plane), phase-over-phase, and cable drops. The switch includes a plurality of switch-pole units carried at desired spacings by a base support and drive arrangement. Each of the switch-pole units includes a housing, interrupting contacts, and disconnect contacts. The housing that encloses the interrupting contacts in movable to perform the disconnect function. The base support and drive arrangement encloses a high-speed interrupting linkage for operation of the interrupting contacts of each of the switch-pole units and carries an operating mechanism that is connected to the interrupting linkage internal to a base support member of the base support and drive arrangement. The switch also includes a disconnect linkage to move the switch-pole housings. For manual operation of the disconnect function, an operating handle is provided.

International Classification:

H01H 3100

US Classification:

200 48R

Abstract:

An arrangement including an insulative support column provides independent rotary and linear drive outputs for the operation of electrical switches, circuit interrupters and/or disconnects or the like. A first, linear drive linkage provides translating motion at a first output in response to linear translating motion at a first input. The linear drive arrangement is provided by an elongated, insulative operating member that is disposed within an elongated bore of the insulative support column, with the operating member extending through the top and bottom ends of the column. A second, rotary drive output is provided by rotation of the support column. The column fixedly carries a lower base member which is rotatably supported within a base housing. The operating member extends through and exits the base member and cooperates with a bearing carried by the base member. The lower end of the operating member is coupled to the linear drive linkage input.

Assignee:

S&C Electric Company - Chicago IL

International Classification:

H01H 3100

US Classification:

200 48A

Abstract:

An operator is provided that includes a common drive for charging an operating mechanism and for driving a functional accessory device in predetermined coordinated relationship. The common drive in a specific embodiment is provided as a drive shaft at the output of a drive train. The operating mechanism is charged as the drive shaft is rotated from a first to a second predetermined position. The functional accessory device is also driven via the drive shaft; the functional accessory device being operated from a first predetermined operational state to a second predetermined operational state in response to the rotation of the drive shaft between the predetermined positions. When desired, the functional accessory device is operated from the second predetermined operational state to the first predetermined operational state by subsequent rotation of the drive shaft to the first predetermined position. The operating mechanism is controlled thereafter to close the contacts of one or more interrupting units. The operating mechanism is capable of immediately opening the contacts of the one or more interrupting units after closing.

US Classification:

361333

Abstract:

An arrangement for efficiently assembling and providing a plurality of circuit protection device configurations by use of major components that are common to the configurations and that are adapted for interconnection and functioning with each other; some of the major components providing different or multiple functions in the various configurations. The various configurations satisfy the application requirements and customer needs with regard to voltage rating, efficient space usage, station layouts, and the provision of disconnect mechanisms. The configurations include various orientations of interrupting units and the provision of various types of disconnect mechanisms. The major components include an operator, an interrupting unit, an insulating support column, and a base drive. The operator provides a first drive output and a second drive output. The insulating support column is capable of being rotated to provide a rotary drive output for disconnect mechanisms.
