Motor Operator System For A Power Switch

US Patent:
7122986, Oct 17, 2006
Filed:
Jan 21, 2003
Appl. No.:
10/348383
Inventors:
Frank G. Willard - Oakmont PA, US
Joseph K. Andreyo - North Huntingdon PA, US
Angelo Rometo - New Stanton PA, US
John R. Klinvex - North Huntingdon PA, US
Assignee:
Cleaveland/Price Inc. - Trafford PA
International Classification:
H02P 1/04
US Classification:
318468, 318266, 318286, 318369, 318467, 307147
Abstract:
A motor and a rotary potentiometer, or other position sensor, running on the motor shaft are mounted in a first enclosure with an output shaft for driving a power switch open or closed. A part of the system outside the first enclosure makes use of a motor position signal from the rotary potentiometer that is processed by a microcontroller that a worker can interact with at a switch panel to set and adjust motor travel limits without needing access into the motor enclosure. The first enclosure and its components can be used for various applications, including those for either underground or pad-mounted switches, which for the latter case can have the first enclosure inside a second enclosure on a pad, and the second enclosure also contains other power and control elements of the system. A portable unit with the switch panel for travel limits can be provided. Other features include a slip clutch, for running a rotary potentiometer from the motor shaft, an overspeed brake of one or more voltage suppressor elements for limiting the speed at which the motor can be turned during a manual switch operation, and a compact, economical structure of the first enclosure.

Motor Operator With Ac Power Circuit Continuity Sensor

US Patent:
6075688, Jun 13, 2000
Filed:
Jun 19, 1998
Appl. No.:
9/100288
Inventors:
Frank G. Willard - Oakmont PA
John R. Klinvex - North Huntingdon PA
Assignee:
Cleaveland/Price Inc. - Trafford PA
International Classification:
H02H 300
US Classification:
361 92
Abstract:
A motor operator with a continuity sensor has a test current injector and a voltage sensor arranged to determine if a loss of AC voltage is due to a discontinuity, such as a blown fuse, in the circuit of a transformer powering the motor operator rather than a loss of voltage from an AC power line. A line voltage detector, such as a resistive or capacitive voltage divider, can also be used with a continuity sensor to distinguish between a discontinuity in the voltage detector and a loss of line voltage. Based on the cause determined by the continuity sensor, signals are generated either to motor operate a disconnect switch or not to.
