Definitions

  • the present invention relates to an electrical remote actuation device.
  • the master switches may be located in places that are not easily accessible, such as cabinets and the like, or in any case at a distance from operators.
  • Remote actuations must meet certain fundamental requirements, such as the ability to apply the force required to operate the levers and to do so with sufficient speed.
  • the aim of the present invention is to provide an electrical remote actuation device that is improved with respect to devices of the background art.
  • an object of the invention is to provide a remote actuation device that is particularly compact.
  • Another object of the invention is to provide a device that offers the greatest assurances of safety and reliability in operation.
  • Another object is to provide a device that can be integrated perfectly with existing electrical units.
  • an electrical remote actuation device including an electric motor that is suitable to actuate, through a control mechanism, the rotation of an actuation shaft that is associated with a kinematic system for the actuation of an electrical circuit breaker, characterized in that the control mechanism includes a preloaded spring that is suitable to provide the actuation shaft with the impulse to open or close the circuit breaker.
  • a device according to the invention includes a containment body 2, which has the classic standardized configuration and forms, at its rear face, a means 3 for coupling to an omega-shaped rail (not shown), according to DIN standards.
  • the containment body 2 has, at its front face, a protrusion 4 that contains the actuation assembly of a handle lever 20, which in turn actuates a handle bar 54 that has a triangular cross-section, protrudes in a per se known manner from the containment body 2, and is associated with the lever for actuating the circuit breaker, not shown, that is coupled to the device.
  • An electric motor 30 actuates a worm screw 45 that engages a gear 40 that is coaxial to the handle lever 20, together with a spring support 41 for a coiled spring 28, and with a pawl 13 that cooperates, in operation, with a release cam 8 that is pivoted on a release cam pivot 31.
  • the lever actuation unit further includes a driving wheel 39, which is also coaxial to the handle lever and to the bar 54 and is suitable to actuate a self-powering lever 17, which in turn acts on a pushbutton 61 of a self-powering microswitch 60.
  • the handle lever 20 is connected, by means of a handle cross-member 42, to an engagement lever 16 that is suitable act on a microswitch lever 21 of a tripping microswitch 121.
  • a reset hook 15 is further associated with the engagement lever 16 by means of a return spring; the hook is suitable to act on a driving lever 19 that rotates about a pivot of the kinematic system 32.
  • the system for changing the direction of the motor 30 includes a handle position lever 22, which is provided with an elastic arc-like portion 122 that includes a stud 222 that acts in contrast with a fixed pivot 322.
  • the handle position lever 22 acts, by virtue of feet 422, on a pushbutton 71 of a handle position microswitch 70 and on a pushbutton 81 of a rotation reversal microswitch 80.
  • the device further includes a locking microswitch 90 on which a locking lever 18 acts, the lever having a portion that is external to the containment body 2 and is provided with a hole 118 for the insertion of a padlock 218 or other device suitable to prevent the locking lever 18 from being moved from the open circuit breaker position shown in Figures 5 and 6.
  • the locking lever 18 provides mechanical locking of the handle lever 20 by acting on an abutment 120 on the handle, as shown more clearly in Figure 6.
  • Figures 3 and 4 show an intermediate position that the locking lever 18 can assume.
  • the locking lever 18 deactivates the device only electrically, by pressing on the pushbutton of the microswitch 90, allowing to actuate the electrical device that is associated with the device without the device being activated.
  • Figures 7 to 10 are views of the steps of the actuation of the circuit breaker and illustrate the relation between the position of the gear and the position of the handle.
  • Figures 11 to 18 are views of the fundamental steps of the closure transition of the circuit breaker by virtue of the device.
  • the preloaded spring 28 pushes the engagement pawl 13 onto an iron tooth 141 of the spring support 41 and the handle of the circuit breaker is in the 0° position, i.e., the open position.
  • the preloaded spring 28 in the open position is shown in Figure 19.
  • the engagement pawl 13 engages the release cam 8 and the handle of the circuit breaker moves through approximately 14°.
  • the gear 40 continues to turn for another 110°, while the engagement pawl 13, rigidly coupled to the shaft 102, remains motionless, further loading the spring 28.
  • the cam 140 rigidly coupled to the gear 40, moves the release cam 8, releasing the engagement pawl 13, which by being pushed by the spring 28 completes the stroke, driving the shaft 102.
  • the handle of the circuit breaker moves from approximately 14° to approximately 84° in the closed circuit breaker position.
  • the gear 40 completes the stroke through another 7° and makes the circuit breaker handle also cover another 6° of rotation, thus reaching 90°, and then resumes rotating in the opposite direction in order to return to the initial position.
  • the spring 28 does not act, and the gear 40 pushes the circuit breaker directly without preventing its natural movement.
  • Figures 24 and 25 are views of the self-powering system of the device, which is based on the driving wheel 39, the rotation of which is actuated by the shaft 102.
  • the protrusion 117 of the self-powering lever 17 is inserted in a recess 139 so that the foot 217 of the lever 17 does not engage the pushbutton 61 of the self-powering microswitch 60.
  • the protrusion 117 instead slides on the surface of the driving wheel 39 and forces the lever 17 to rotate toward the microswitch so that the foot 217 of the lever acts on the pushbutton 61.
  • Figures 20 to 23 are views of the condition of the tripping microswitch 121 in relation to the four fundamental positions of the circuit breaker.
  • the tripping microswitch 121 is open when the circuit breaker is in the open-tripped position; as shown in Figure 21, the tripping microswitch 121 is closed when the circuit breaker is in the open-armed position; as shown in Figure 22, the tripping microswitch 121 is closed when the circuit breaker is in the closed-armed position; and finally, as shown in Figure 23, the tripping microswitch 121 is open when the circuit breaker is in the closed-tripped position.
  • the position of the handle that corresponds to the position in which the circuit breaker is open or closed determines the direction of rotation of the motor depending on the basis of the system shown in Figures 26-29, which is characterized by the presence of the handle position lever 22 that is provided with an elastic arc-like portion 122 that includes the stud 222 that acts in contrast with a fixed pivot 322 in order to produce a bistable condition of the position lever.
  • Figures 26 and 28 illustrate the position of the handle and of the position lever 22 that corresponds to the open condition of the circuit breaker
  • Figures 27 and 28 illustrate the position of the handle and of the position lever 22 that corresponds to the position in which the circuit breaker is closed.
  • the action of the position lever 22 on the handle position microswitch 70 and on the rotation reversal microswitch 80 indicates to the device the position of the handle and the direction of rotation of the motor.
  • an electrical remote actuation device having been provided that uses, by virtue of its particular kinematic structure, a low-power motor.
  • the device according to the invention can be used with a complete range of electrical units, generally designated by the reference numeral 101, and accessories such as contacts, generally designated by the reference numeral 201.
  • the device can also be associated with a unit that does not have the coupling for a triangular bar, such as a pure residual current-operated device, generally designated by the reference numeral 301, by means of a module 401 that is provided with an external actuation member 402 that is suitable to act on the handle of the residual current-operated device 301.
  • a unit that does not have the coupling for a triangular bar such as a pure residual current-operated device, generally designated by the reference numeral 301, by means of a module 401 that is provided with an external actuation member 402 that is suitable to act on the handle of the residual current-operated device 301.
  • the module 401 may also act as an automatic reset device in case of tripping following a fault of the circuit breaker with a selector of the number of authorized reclosings and adjustment of the maximum time within which the auxiliary device can perform the set reclosings.
  • the materials used, as well as the dimensions, may of course be any according to requirements and to the state of the art.
