| A handle operator slide and a motor operator slide are individually coupled with a charging mechanism to independently charge charging springs thereof. The charging mechanism is operative to charge the springs of a contact operating mechanism as the charging springs discharge. The charging mechanism includes a prop controlled by the condition of the operating mechanism to releasably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releasably sustain the breaker contacts open against the urgence of fully charged operating mechanism springs. Consequently, the circuit breaker is capable of executing multiple contact opening and closing operations without recharging the charging springs by either the handle or the motor via their respective slides. | ||||||

| Motorized high voltage switch operating mechanisms may have local control switches located on the front thereof which may be operated to control the operation of the switch operating mechanism. It is desirable to limit access to the local control switches by a cover that may be locked to prevent unauthorized tampering or actuation. A cover is provided that is pivotable on a hinge to cover the switches. The cover is arranged so that it may be opened in two ways. First, when a lock is removed, the cover may be first moved upwardly to disengage a flange mounted on a door of the switch operating mechanism so that the cover can be pivoted to an open position. Second, even when the lock is in place, the door can be opened so that the flange disengages the cover so that the cover can be pivoted to an open position. A remote control blocking switch may be mounted beneath and normally engaged by the cover so that when the cover is opened, remote operation of the switch operating mechanism is blocked by disengagement of the switch from the cover. | ||||||
| 143 | Spiral operating mechanism for high voltage switch | US563964 | 1975-04-01 | US3980977A | 1976-09-14 | David M. Evans |
| A spiral spring interconnects a pivotably mounted drive lever that may be pivoted either by hand or by a motor, and a pivotably mounted toggle lever that is operably connected to a switch. The toggle lever is held in the switch-closed or the switch-opened positions by main latches which hold the toggle lever in position while the drive lever is pivoted to bias the spring. Once the spring is biased, stop latches engage the drive lever holding it in a spring biased position. The main latches may then be either manually operated or operated by solenoids connected to control circuitry to release the toggle lever so that the spring will react against the toggle lever to either open or close the switch depending on the position of the switch at the initiation of operation. Once the switch has either opened or closed, the spring may be either recharged automatically by the motor, or if manual operation is desired, the motor can be disabled so that the spring can be biased by manual rotation of the drive lever. A clutch mechanism is provided to disconnect the motor from the mechanism when a manual tool is inserted into the mechanism. Also provided is a shutter bolt that locks out automatic operation of the main latches when the manual tool is inserted, electrically disconnects the motor, and prevents manual operation of the main latches when the tool is inserted into the mechanism. Also, if it is desirable to test the solenoids without tripping the main latches, a mechanism is provided to manually disconnect solenoids from the main latches. In addition, in case the switch blade is welded or stuck in the closed position, an automatic pry-out mechanism is provided to assure contact separation during switch opening. | ||||||

| The invention relates to an actuator for operating a positioning element. A common requirement in such actuators is that the positioning element can be decoupled from the electric motor that drives the positioning element via a transmission. In some applications the actuators are so compact that the only way to decouple the actuator is to disassemble parts of the actuator. To connect the positioning element to the electric motor again, this however requires that the whole actuator is demounted so as to ensure that the disassembled parts are properly assembled. The present invention overcomes this problem by providing an actuator comprising two toothed wheels which by mutual displacement can be brought out of mesh and which each comprises at least two toothed rims positioned with a spacing corresponding to at least the width of one toothed rim. Hence the provided actuator is very compact in that the space required for disengagement of the positioning element is practically reduced to the width of the toothed wheels. Further the construction ensures a firm mesh, making the actuator highly reliable. | ||||||

| A switching apparatus has a frame with a circular notch in its operating surface; a operating handle disposed in the notch, said handle can change from a lower position corresponding to automatic mode to a upper position corresponding to manual mode, and the handle are rotatable in said circular notch in both positions; and gearing mechanism disposed in the frame, said gearing mechanism comprise a main gear, a clutch gear coupled to a motor, and a switch gear coupled to the main gear. The main gear, the clutch gear and the handle consist of a clutch device, such that in automatic mode the main gear engages the clutch gear and in manual mode the main gear disengaged from the clutch gear. Because the motor is disengaged from the main gear in the manual mode, the rotation of the operating handle will not interact with motor, so avoids possible confliction and resultant damage. | ||||||
| 160 | Motor operator for switchgear for mains power distribution systems | US12311971 | 2007-10-31 | US20100008022A1 | 2010-01-14 | Bruno Christensen; Anders Lorenzen; Verner Smidt; Jens N. Paulsen; Glenn Smith |
| A power operator for switchgear (1) for mains power distribution systems, where the switchgear comprises a closed cabinet (5) with an operating shaft protruding there from. The operating shaft is rotable at least between two positions and has a coupling part (2, 3). The operator comprises a housing (10), which is mountable on the external surface (4) of the switchgear housing, and a rotatable connection shaft (14) connected to an electric drive mechanism (11). It has a first coupling part to fit with the coupling part of the operating shaft in a longitudinal axial sliding and non-rotational interlocking manner. The coupling part of the connection shaft (14) is a separate interchangeable part (24, 24a) of the connection shaft attached thereto by non-rotational interlocking means. Further, it has an activation knob (16) extending from the housing (10) to operate the switch manually. With an interchangeable coupling part (24, 24a) the motor operator could easily be adapted to various switchgear simply by choosing a coupling part (24, 24a) fitting the coupling (2, 2a, 3) on the switchgear. | ||||||
