Definitions

  • the present invention relates to an auxiliary actuation device for opening a low-voltage circuit breaker associated therewith following a remotely issued opening command. More particularly, the present invention relates to an auxiliary device known in the art as a shunt tripping relay which has improved shape and characteristics.
  • Document FR 2 567 317 discloses a device according to the preamble of claim 1.
  • an actuating auxiliary device can be constituted by a shunt tripping relay which, following an intervention command received from an operator, mechanically forces the opening of the associated circuit breaker.
  • the circuit breaker changes state, changing from a condition in which the contacts are closed to one in which the contacts are open, and by means of appropriate lever systems it triggers a kinematic mechanism inside a device for signaling the state of the circuit breaker associated therewith, which accordingly constitutes an actuated device.
  • the actuated device provides operators with a signal which corresponds to the current state of the circuit breaker.
  • one of the solutions generally used entails placing all the accessories on a same side of the circuit breaker relative to a front view of said circuit breaker.
  • the mechanical connection between the circuit breaker and the accessories is achieved by using a shaft which is shaped so as to have multiple protrusions and transmits the movements among the various components, according to a solution which is particularly disadvantageous from the point of view of production as well as from the point of view of functionality.
  • the shaft that is used in fact requires accurate machining in order to form the protrusions and the dimensions required to take into account the different stress levels and the considerable clearances involved. This leads to an increase in production costs and possibly to a reduction in the precision and overall reliability of the assembly constituted by the circuit breakers and the auxiliary devices.
  • Another solution that is used for coupling the circuit breaker and the auxiliary device is to distribute the devices on both sides of the circuit breaker; in particular, relative to a front view of the circuit breaker, the actuating auxiliary devices according to the present invention are always fitted on the same side of the circuit breaker, for example on the left, while the actuated ones are fitted on the other side, on the right.
  • This coupling solution is particularly advantageous with respect to the one described earlier both because it considerably facilitates users in practical applications and because it allows to use a shaft with a smaller number of protrusions, which is accordingly simpler and cheaper to machine; the mechanical stresses that occur are more balanced and clearance is reduced.
  • magnetothermal and residual-current low-voltage circuit breakers have moving contacts which are mechanically mutually different and can be arranged differently inside the circuit breakers according to specific applications and/or to the applicable national standards.
  • the moving contacts comprise phase contacts and neutral contacts which are mechanically different from each other and can be located either on the right side or on the left side of said circuit breaker relative to a front view thereof.
  • the shunt tripping relay is an actuating auxiliary device, it is generally always fitted on the same side of the circuit breaker, for example on the left; in the current state of the art, this leads to the need to produce multiple separate series of auxiliary devices according to the constructive structure of the circuit breaker to which they will be coupled, increasing constructive complexity and production costs.
  • the kinematic mechanisms for opening the contacts of the circuit breaker can be affected negatively by the corresponding kinematic systems of the auxiliary device; in particular, the opening speed of the circuit breaker might be reduced, accordingly leading to malfunctions or even to breakage of the circuit breaker.
  • a further drawback is that if a remote operator sends a command to open the circuit breaker, in the current state of the art conventional actuating auxiliary devices are not provided with means for local visual indication means which protrude outside the device and allow easy and immediate identification of the tripped circuit breaker; this also prevents resetting the auxiliary device without directly acting on the open circuit breaker.
  • the aim of the present invention is to provide an auxiliary device for opening a circuit breaker associated therewith following a remotely issued opening command wherein the coupling to the circuit breaker occurs fully independently of the arrangement of the contacts inside it, with a considerable benefit from the point of view of production.
  • an object of the present invention is to provide an auxiliary device for opening a circuit breaker associated therewith following a remotely issued opening command in which the coupling to the circuit breaker does not affect the kinematic mechanisms of said circuit breaker, thus preserving its design characteristics, particularly in terms of speed of contact opening in case of triggering due for example to a fault.
  • Another object of the present invention is to provide an auxiliary device for opening a circuit breaker associated therewith following a remotely issued opening command in which there is provided a local visual indication of the open state of the circuit breaker due to said remote command.
  • Another object of the present invention is to provide an auxiliary device for opening a circuit breaker associated therewith following a remotely issued opening command in which it is possible to reset the auxiliary device without a direct intervention on said circuit breaker.
  • Another object of the present invention is to provide an auxiliary device for opening a circuit breaker associated therewith following a remotely issued opening command which is highly reliable, relatively easy to manufacture and at competitive costs.
  • the device thus conceived ensures a coupling to the circuit breaker associated therewith which is entirely independent of the mechanical structure of the circuit breaker and of the arrangement of the contacts inside it. Moreover, the coupling does not affect at all the performance of the circuit breaker, particularly as regards the opening speed of the contacts during triggering due for example to a fault.
  • the auxiliary actuation device comprises an insulating enclosure 1 inside which there are fixed contacts 20 and 20' which operatively couple to a moving contact 29 (changeover contact), for example of the laminar type. Said contacts are electrically connected to connection terminals, respectively an upper terminal 16, a central terminal 17 and a lower terminal 18.
  • connection terminals respectively an upper terminal 16, a central terminal 17 and a lower terminal 18.
  • the figures show only one upper terminal 16, but the device according to the present invention actually uses a second upper terminal 16.
  • the four-terminal configuration allows, by means of a suitable electric circuit, to visually indicate to a remotely located operator the change of state of the circuit breaker; this indication can be easily achieved by means of two lamps of mutually different colors which indicate an open or closed state of the circuit breaker.
  • an electromagnetic part which comprises a fixed magnet 21 on which a coil 12 is wound and a moving magnet 22 which is pivoted in a point 100 and with which a spring 28 is associated; the coil 12 is operatively associated to a power supply circuit.
  • the coil 12 in normal operating conditions, i.e., when the associated circuit breaker is closed, the coil 12 is not supplied with electric power and the moving magnet 22 is spaced from the fixed magnet 21.
  • the coil 12 In order to open the circuit breaker due to a remote command, issued for example by an operator who acts on a button, the coil 12 is excited by current pulses which facilitate the generation of a magnetic field of suitable intensity.
  • the moving magnet 22 is attracted by the fixed magnet 21 and by overcoming the resistance of the spring 28 it performs a movement which is equal to the existing gap, as shown in Figure 3.
  • the movement of the moving magnet 22 toward the fixed magnet 21 actuates a suitable kinematic mechanism which opens the circuit breaker in a manner described in detail hereinafter.
  • the device according to the invention comprises means for coupling to the circuit breaker which comprise a triggering lever 5, a coupling lever 6 and a transmission lever 10 whose function and connections are described hereinafter.
  • Actuation means actuated by the moving magnet comprise an actuation lever 9.
  • the device also comprises means for interacting with the moving contact 29, which comprise an interaction lever 13, and a kinematic chain which comprises a second actuation lever 9 and a U-shaped element 32 for the purposes which will be described hereinafter.
  • means are provided for the local visual indication of the open state of the circuit breaker due to a remote opening command; such means comprise a reset and indication lever 7 and an engagement lever 11.
  • the transmission lever 10 is pivoted to a point 101 of the enclosure 1 which is operatively connected to the circuit breaker and with which a return spring 25 is associated; the engagement lever 11 is also arranged on the same pivoting point 101, while the reset and indication lever 7 is pivoted in a point 103 of the enclosure 1.
  • the transmission lever 10 is detachably connected, by means of the U-shaped element 32, to the actuation lever 4 and to the tripping lever 5, which are pivoted to a point 102 of the enclosure 1; an actuation spring 26, whose function is described in greater detail hereinafter, acts on the lever 4.
  • the actuation lever 4 in a position of the device that corresponds to the one in which the circuit breaker is closed, the actuation lever 4 has a raised portion 19 at which one end 13' of the interaction lever 13 is laterally adjacent.
  • the lever 13 is freely pivoted to a point 104 of the enclosure 1 and has an end 13" which abuts against the lamina of the moving contact 29. In this manner, by means of the action applied by the protrusion 19 to the end 13', the lever 13 prevents the movement of the lamina 29.
  • the lamina 4 also has a pivot 30 which can interact with the surface of a slot 31 of the lever 7 and a groove 33 in which the U-shaped element 32 can slide.
  • the tripping lever 5 comprises a pivot 14 for coupling to the tripping mechanism of the circuit breaker and has the particularity that it is provided with a toothed sector 2 whose function is described hereinafter.
  • the reset and indication lever 7 has, in addition to the slot 31, a first raised portion 34, on which a first end of a spring 24 acts, and a second raised portion 35, which interacts against a shaped wall 36 of the engagement lever 11.
  • the engagement lever 11, shown in detail in Figure 5, also has a pivot 50 on which the second end of the spring 24 acts.
  • the spring 24 pushes on one side against the raised portion 34, forcing the lever 7 to turn clockwise, and against the pivot 50 at the other side, forcing the lever 11 to turn counterclockwise. Accordingly, the levers 7 and 11 move against each other, facilitating contact between the raised portion 35 and the shaped wall 36 and remaining engaged in the inactive position shown in Figure 1.
  • the lever 9 is pivoted to a point 100 of the enclosure 1 and it is associated with a return spring 28.
  • the lever 9 is composed of two parts: a first part is shaped so as to form a seat 42 for geometric coupling to the moving magnet 22 and a second part protrudes from the first one, two slots 37 and 38 being formed thereon.
  • the second part is shaped so as to have an oblique flat portion 39, which can interact with the pivot 14 of the lever 5, and a wing 40 which protrudes substantially perpendicular to the median plane of the lever 9 and is suitable to interact with the pivot 50 of the lever 11.
  • the device according to the invention comprises an additional coupling lever 6, pivoted to the point 103, which has a pivot 15 for optional coupling to the kinematic mechanism of the associated circuit breaker, and a toothed sector 3 which is operatively coupled to the toothed sector 2 of the tripping lever 5.
  • the two toothed sectors 2 and 3 mutually mesh, rotating with respect to each other in opposite directions.
  • This constructive solution allows to provide a coupling of the auxiliary device to the circuit breaker which is fully independent of the arrangement of the contacts inside it. If the position of the poles in the circuit breaker changes, the coupling between the auxiliary device and the circuit breaker can be provided either on the pivot 14 or on the pivot 15; moreover, the change in the direction of rotation of the mechanism of the circuit breaker according to the arrangement of the poles is rendered irrelevant in terms of the functionality of the coupling between the circuit breaker and the device by the presence of the two mutually contrarotating toothed sectors 2 and 3.
  • the lever 7 has a shaped protrusion 60 which, when the circuit breaker opens due to a command issued remotely by a remote operator by means of a pushbutton or a control panel, protrudes from a corresponding opening 61 formed in the enclosure 1 and therefore allows local visual indication of the tripping of the associated circuit breaker.
  • the protrusion 60 directly provides a button on which an operator can, for any requirement, act directly and restore the auxiliary device without having to act on the associated circuit breaker, which accordingly remains open.
  • the lever 7 therefore simultaneously provides local indication of an open circuit breaker and resetting of said auxiliary device.
  • said protrusion might be associated with other levers of the kinematic mechanism of the device.
  • the kinematic mechanism of the circuit breaker transmits the motion to the transmission lever 10, which turns in the direction indicated by the arrow 105, pulling the U-shaped element 32 and reaching, at the end of its motion, the position shown in Figure 2.
  • the lever 4 under the action of the U-shaped element 32, rotates about its own pivoting axis 102, in the direction indicated by the arrow 106, and reaches the position shown in Figure 2.
  • the levers 5 and 6 also rotate in mutually opposite directions, causing the meshing of the two toothed sectors 2 and 3.
  • the lever 13, once its end 13' has disengaged releases the lamina 29, which by means of its elastic loading facilitates the switching of the moving contact from the first fixed contact 20 to the second fixed contact 20'.
  • the remaining part of the mechanism is substantially not affected by the movement.
  • the coil 12 is excited by a current pulse which produces a magnetic field whose intensity is adequate to facilitate the attraction of the moving magnet 22 toward the fixed magnet 21.
  • the moving magnet 22 is capable of crossing the existing gap and by rotating it couples electromagnetically to the fixed magnet 21. Said movement is transmitted to the lever 9, which also rotates about its pivoting axis 100. Through this rotation, the oblique flat portion 39 pushes against the pivot 14 of the lever 5, forcing it to rotate in the direction indicated by the arrow 107.
  • the toothed sector 2 meshes with the toothed sector 3 of the lever 6, causing the movement of the pivot 15 in the slot 38: in this manner, the circuit breaker receives motion either directly by means of the pivot 14 or indirectly from the lever 6 by means of the pivot 15 and the meshing of the two toothed sectors 2 and 3; moreover, by means of this rotation the tripping lever 5 disengages the U-shaped element 32, which becomes able to slide freely in the groove 33 of the lever 4.
  • the actuation lever 4 no longer locked by the U-shaped element 32, rotates under the action of the thrust of the spring 26 in the direction indicated by the arrow 106 and simultaneously facilitates a faster rotation of the lever 5.
  • This simultaneous rotation is achieved by means of a spring, not shown, which is interposed between the levers 4 and 5 and couples their movement; said spring is conveniently inserted in a seat 80 of the lever 4.
  • the moving contact therefore advantageously acts as a contact for automatically de-energizing the coil; moreover, when the moving contact changes position, the four-terminal configuration allows to visually indicate to a remote operator that the circuit breaker is open, as described earlier.
  • the wing 40 of the lever 9 interacts with the pivot 50, pushing it toward the inside of the device and disengaging the shaped wall 36 from the engagement with the raised portion 35.
  • the lever 7, pushed by the action of the spring 24 on the raised portion 34 rotates about the pivoting axis 103 and the shaped protrusion 60 protrudes from the enclosure 1 through an opening 61, providing a local visual indication that the circuit breaker has tripped.
  • the transmission lever 10 following the movement of the associated circuit breaker, reaches the position shown in Figure 3, in which the U-shaped element 32 re-engages the levers 4 and 5.
  • the device can also be reset by acting on the control knob of the circuit breaker.
  • the movement is transmitted from the circuit breaker to the transmission lever 10 which pushes the lever 4 by means of the U-shaped element 32; the pivot 30, during the movement of the lever 4, acts against the surface of the slot 31 of the lever 7 and pulls it downward, causing it to rotate.
  • the raised portion 35 couples to the shaped wall 36, as described earlier.
  • the protrusion 19 engages the end 13' of the lever 13 which, by rotating about its pivoting axis 104, acts on the lamina of the moving contact 29 and returns it onto the fixed contact 20.
  • the auxiliary actuation device according to the invention fully achieves the intended aim, since it allows to provide a coupling with the circuit breaker independently of the mechanical structure of the circuit breaker and of the arrangement of the contacts inside it without affecting its performance in any way; moreover, thanks to the adoption of the above-described particular constructive refinements, it is possible to locally and directly identify the opening of the circuit breaker, with consequent reset of said device without acting on the circuit breaker.
