Definitions

  • FR3121270A1 describes a protective device for protecting against overloads, short circuits and differential electrical faults.
  • This device which is generally satisfactory, comprises a stirrup spring and a drawer which is configured to switch from an initial armed position to a free position, when an electrical fault occurs, then automatically return to its initial armed position under the action of the stirrup spring.
  • the mechanical power developed by the stirrup spring is not always sufficient to allow the drawer to return to its initial armed position.
  • the aim of the present invention is to remedy the aforementioned drawback by proposing a new electrical protection device in which the return of the drawer to its initial armed position is made more reliable.
  • the electrical protection device also comprises a first trigger, which is housed in the housing and which is configured to trigger a switching of the switching mechanism from the armed configuration to the triggered configuration when the first trigger is energized by an electrical fault, and a switching handle movable in rotation about a handle axis, actuable by a user between an open position, to put the switching mechanism in the triggered configuration, and a closed position, to put the switching mechanism in the armed configuration, and actuable by the switching mechanism from its closed position to its open position, when the switching mechanism is switched into the triggered configuration under the effect of the first trigger.
  • a first trigger which is housed in the housing and which is configured to trigger a switching of the switching mechanism from the armed configuration to the triggered configuration when the first trigger is energized by an electrical fault
  • a switching handle movable in rotation about a handle axis, actuable by a user between an open position, to put the switching mechanism in the triggered configuration, and a closed position, to put the switching mechanism in the armed configuration
  • the electrical protection device further comprises a reset hook, kinematically linked to the switching handle, such that it moves with the switching handle during a rotation of the switching handle around the handle axis between its open position and its closed position, while the drawer carries a drawer hook. Furthermore, when the drawer is in the free position, the reset hook and the drawer hook are opposite each other and ready to be engaged under the effect of the rotation of the switching handle between its open position and its closed position and the lock is held in the unlocked position by the drawer. When the drawer is in the armed position, the drawer hook and the reset hook are distant from each other.
  • the housing 2 comprises another half-shell not visible in the figures and generally symmetrical to that which is shown, with respect to a plane P2 which delimits the half-shell on its side visible to the Figure 1 .
  • the electrical protection device 1 comprises a first conduction path 3, which comprises a first movable contact 11 and a first fixed contact 12.
  • the first conduction path 3, visible in particular at figures 1 And 2 is sometimes called neutral.
  • the contact 12 is fixed relative to the housing 2 and located opposite the movable contact 11, in the Z direction.
  • the movable contact 11 preferably comprises a conductive end 13, ensuring the electrical contact function.
  • the movable contact 11 preferably comprises a contact holder 15, which carries the end 13.
  • the movable contact 11 is pivotable, relative to the housing 2, by means of the contact holder 15, around a movable contact axis X11, parallel to the X direction.
  • the movable contacts 11 and 21 are advantageously pivotable relative to the housing 2 independently. When they move from their respective insulating positions to their respective conduction positions, the movable contacts 11 and 21 advantageously rotate in the same direction. In particular, the conductive ends 13 and 23 are then moved essentially in the Z direction.
  • the trigger 30 comprises a differential current sensor, not shown, and a relay 31.
  • the relay 31 here comprises a movable rod 32, which is moved relative to the housing 2 between an armed position, shown in the Figure 2 , and a triggered position not shown, when the trigger 30 is energized.
  • the movement of the rod 32 from the armed position to the triggered position is carried out in the Z direction.
  • the operation of the trigger 30 is in accordance with the technical teaching of FR3121270A1 .
  • the movable rod 32 Once the movable rod 32 has reached the triggered position, it should be returned to the armed position to reset the relay 31 and thus allow the relay 31 to actuate the rod 32 again in the event of a differential fault.
  • the switching mechanism 40 is housed in the housing 2.
  • the switching mechanism 40 is configured to switch between an armed configuration, shown in Figure 2 , in which the switching mechanism 40 places the first and second movable contacts 11 and 21 in the conduction position, and a triggered configuration, partially shown in the Figure 4 , in which the switching mechanism 40 places the first and second movable contacts 11 and 21 in the isolated position.
  • This switching is enabled by a spring 93, which tends to switch the switching mechanism 40 into its triggered configuration.
  • the electrical protection device 1 also comprises a switching handle 50.
  • the switching handle 50 is designed to be operated by a user, between an open position and a closed position and vice versa.
  • the switching lever 50 is pivotable relative to the housing 2, around a lever axis X50, parallel to the X axis, between a closed position, shown in the figures 2 And 3 , and an opening position, shown on the Figure 4 .
  • the switching mechanism 40 advantageously comprises a spring 53, called a “control spring”, visible on the figures 1 , 2 And 9 .
  • the control spring 53 applies, to the switching lever 50 and by bearing on the housing 2, a torque around the lever axis X50 which tends to return the switching lever 50 from its closed position to its open position.
  • the control spring 53 is a helical torsion spring, housed inside the base 51 around the lever axis X50, and one branch of which bears on the switching lever 50 and another branch of which bears on the inside of the housing 2.
  • the position of the switching handle 50 visually indicates to the user the current configuration commanded for the electrical protection device 1, namely a placing in the isolation position of the first and second movable contacts 11 and 21 when the switching handle 50 is in the open position, and a placing in the conduction position of the first and second movable contacts 11 and 21, when the switching handle 50 is in the closed position.
  • the differential trigger 30 actuates a force amplifier 60, as shown in detail in the figures 3 to 9
  • the force amplifier 60 is entirely separate from the switching mechanism 40, and essentially comprises a drawer 61, a lock 62, a drawer spring 63, but also preferably a return spring 64 and a reset blade 65.
  • THE figures 3 to 7 show a detail of the electrical protection device 1, where certain parts of the electrical protection device 1 are not visible in order to improve the visibility of certain parts of the force amplifier 60.
  • the drawer 61 is movable in translation, relative to the housing 2, between an armed position, shown in the Figure 3 , and a free position, shown on the figures 4 , 5 And 8 .
  • the drawer 61 slides relative to the housing 2 along an axis A61, which is fixed relative to the housing 2.
  • the axis A61 is preferably included in a plane parallel to the directions Y and Z.
  • the axis A61 is oblique relative to the directions Y and Z.
  • the drawer 61 is preferably moved in a direction which has a horizontal component in the direction of the direction Z to be moved to the free position.
  • the resetting hook 70 and the drawer hook 68 have their respective ends adapted to be engaged, when in contact, by being curved complementary to each other.
  • the repositioning of the drawer 61, from the free position to the armed position, is carried out by the cooperation of the drawer hook 68 and the resetting hook 70.
  • the actuation of the switching lever 50 by a user causes the switching lever 50 to pivot around the axis X50 in the direction of the arrow A1 at figures 5 to 7 , and pivots the resetting hook 70 in the same direction, in an arc-shaped movement around the axis X50.
  • the resetting hook 70 therefore has a movement with a horizontal component opposite to the direction Z.
  • the end 702 of the resetting hook 70 then comes to bear against the end 682 of the drawer hook 68, as seen in the Figure 5 .
  • the resetting hooks 70 and drawer hook 68 are engaged and can cooperate mechanically.
  • a ramp 80 is provided on the housing 2, adjacent to the drawer 61 in the X direction.
  • the resetting hook 70 is in sliding support against the ramp 80 and crosses the ramp 80 when the switching lever 50 moves from the open position to the closed position.
  • the movable contact 11 drives the reset blade 65 into its first position.
  • the contact holder 15 comprises an arm 152 which comes to bear against the reset blade 65, in the opposite direction to the Z direction.
  • the reset blade 65 is thus moved into its first position, or even beyond its first position, pushing the movable rod 32 in the direction opposite to the Z direction, thus resetting the trigger 30.
  • the switching lever 50 comprises a snap-close pawl 54, pivoting relative to the housing 2 around the lever axis X50 and more particularly visible at the figure 9 .
  • the first and second movable contacts 11 and 21 respectively approach the fixed contacts 12 and 22 in the direction Z, pivoting around the axis X11 under the action of the switching mechanism 40.
  • the pivoting of the movable contact 21 is interrupted halfway by the sudden closing pawl 54, which comes to bear on a leg 26 of the contact holder 25, which prevents further pivoting of the movable contact 21 in the direction of the fixed contact 22.
  • the movable contact 11 continues to pivot until it comes into contact with the fixed contact 12.
  • the snap-closing pawl 54 cooperates with the leg 26 so as to hold the second movable contact 21 in its insulating position over a first portion of the closing stroke of the switching handle 50 and to release the second movable contact 21 upon passing a predetermined point of the movement stroke of the switching handle 50, after the movable contact 11 has already reached its conduction position.
  • This ensures that, when closing the electrical protection device 1, the neutral conduction path 3 is closed before the phase conduction path 4. This makes it possible to avoid the formation of an electric arc during the passage of the second movable contact 21 in the conduction position, in particular in the case where the actuation of the switching lever 50 by the user is very slow.
  • the indicator light 90 is in a visible position to indicate to the user that the first and second moving contacts 11 and 21 have been put in the isolation position by the trigger 30.
  • the indicator light 90 allows the user to distinguish the type of fault which led to the first and second moving contacts 11 and 21 being put in the isolation position by the electrical protection device 1, here a differential fault.
  • the indicator light 90 is therefore a so-called “specific fault” indicator light.
  • the indicator light 90 is in a non-visible position when the contacts 11 and 21 are in the conduction position and when the contacts 11 and 21 are in the isolation position, having been put in the isolation position by putting the switching handle 50 in the open position, while the trigger 30 has not been energized. When the switching lever 50 is moved from the open position to the closed position by the user, the indicator light 90 is set or maintained in the non-visible position.
  • the electrical protection device 1 is reliably reset, using the switching handle 50 which drives the resetting hook 70, resetting the force amplifier 60 when the switching handle moves from the open position to the closed position.
  • Resetting the electrical protection device 1 is such that the differential trip device 30 is reset before the flow of current is restored. Therefore, if the differential fault persists, the electrical protection device 1 cuts off the current again, as soon as it is reset. The correct operation of the electrical protection device 1 is thus guaranteed, without making any changes in use for the user, who does not have to carry out any additional operations to reset the electrical protection device 1, compared to what he knows from known equipment.
