| 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. | ||||||

| 107 | Electromechanical switching device and arrangement with several switching devices | US793657 | 1997-05-13 | US5844493A | 1998-12-01 | Fritz Pohl; Wilfried Jaehner |
| Switching devices can have means for contactless switching position detection. According to the invention, magnetic field sensors arranged at suitable locations inside and/or outside a device housing are provided for switching position detection. In particular, position-dependent magnetic fields are measured for ON/OFF position detection, overcurrent triggering, and contact welding; however, the magnetic field of the current flowing is detected to recognize short-circuit triggering. Differential Hall effect sensors and Reed contacts, respectively, can be used for these purposes. In addition, a sound sensor can be provided for detecting the switching noise, whose signal is evaluated together with the overcurrent triggering signal for short-circuit detection. | ||||||

| 109 | Common alarm system for a plurality of circuit interrupters | US241225 | 1994-05-10 | US5493278A | 1996-02-20 | Raymond W. Mackenzie; John A. Wafer |
| Apparatus for generating alarms for a group of circuit interrupters, especially those which respond to arcing faults, includes a device associated with each circuit interrupter providing an indication of a tripped condition and a common alarm generator which generates an alarm when any one, or at least any one of a number of selected circuit interrupters, is in the tripped condition. In one embodiment of the invention, switches indicating that associated circuit interrupters are tripped generate auxiliary trip signals on a common alarm bus. The auxiliary trip signals are latched by a latch on the common alarm bus which energizes a relay to activate a local and/or remote alarm. The latch is reset by a switch on the load center door. In another embodiment of the invention, an IR beam is blocked from reaching a photo-detector whenever a circuit interrupter handle is in the tripped position which also results in energization of a relay to actuate the common alarm. Selected circuit interrupters only can be alarmed by orienting the light beam such that only circuit interrupters selected by adding an extension to the handle block the beam when the associated circuit interrupter is tripped. | ||||||

| A circuit breaker includes a current entry which conducts an electrical current via a wound coil conductor strip of a first coil to a first fixed contact, and includes a contact rocker which can be moved between two switching positions. The contact rocker includes mutually connected contact limbs. A first switching position of the contact rocker, electrically connects the first fixed contact with a second fixed contact which is connected via a wound coil conductor strip of a second coil to a current exit for dissipating an electrical current flowing through the contact limbs of the contact rocker and the coil conductor strips of the coils to a current exit of the circuit breaker. A high electrical current which flows through the wound coil conductor strips of the coils and through the contact limbs of the contact rocker produces a magnetic field which generates a switching force which moves the contact rocker from the first switching position into a second switching position in which the two fixed contacts are electrically separated to interrupt the electrical current. | ||||||
