  • the switch is formed on the actuator, by contact or separation between the movable armature and the fixed yoke of the actuator.
  • the switch is remotely controlled by magnetic effect with the aid of a permanent magnet positioned on the actuator.
  • the movable armature is mounted on a spring with respect to the fixed yoke and in that the electric detection circuit (6) uses the spring as an electrical conductor.
  • the spring is mounted on a conductive plate connected to the electrical detection circuit.
  • the method comprises a step of controlling the level of control current injected into the control coil.
  • the step of measuring the control current passing through the control coil during the separation of the moving armature with respect to the fixed yoke is implemented during a phase of maintaining the moving contact in its closed state with respect to the fixed contact.

  • a switch-type electrical switch device comprises, in known manner, an electromagnetic type actuator 1, one or more poles (for example three poles for a three-pole contactor) with, for each pole, a movable member set in motion by the actuator, one or more movable contacts 21 carried by the movable member and one or more fixed contacts 20.
  • the actuator 1 more particularly comprises a fixed yoke 10 and a movable armature 11 adapted to move relative to the fixed yoke 10 between two positions , an open position ( Figure 1A ) and a closed position ( figure 1C ).
  • the electromagnetic actuator also comprises a control coil 3 controlled by a control current in order to move the mobile armature 11 from its open position to its closed position and a return spring 4 positioned between its fixed yoke 10 and its mobile armature 11 to move the movable armature 11 from its closed position to its open position.
  • the movable member is for example a movable double break bridge carrying two movable contacts 21 movable between two states, an open state and a closed state, according to the position of the movable armature 11 of the actuator 1.
  • the electrical apparatus comprises a pole spring 5 for crushing the movable contacts 21 against the fixed contacts 20 when the movable armature 11 is in the closed position.
  • the invention described below will be able to operate with a simple rupture type mobile member.
  • Figures 1A to 1C show only one pole of the electrical switch device. It should be understood that the invention applies to all the poles of the apparatus.
  • the movable armature 11 is in its closing stroke by injecting a control current into the control coil 3 of the actuator 1.
  • the control current must be sufficient to counter the effort provided. by the return spring 4.
  • the movable contacts 21 are brought to the closed state by the actuator 1 but the pole spring 5 is not biased.
  • the movable armature 11 completes its closing stroke and is kept in its closed position relative to the fixed yoke 10 by injecting a sufficient control current into the control coil 3 of the actuator 1.
  • the return spring 4 is compressed to the maximum between the movable armature 11 and the fixed breech 10.
  • the movable contacts 21 are kept in the closed state and are crushed against the fixed contacts 20 by means of the pole spring 5 which is compressed by means of the actuator 1.
  • the pole springs 5 will be more or less compressed and the force provided by the actuator 1 will be more or less important. Indeed, the less the contacts 20, 21 are worn, the more pole springs 5 are compressed and therefore the force provided by the actuator 1 to compress these springs must be important. Therefore, it is possible to correlate the wear level of the contacts with the force provided by the actuator to compress the pole springs 5.
  • the figure 2 schematically shows the force profile provided by the actuator 1 during the total opening / closing stroke Ct performed by the movable armature 11 relative to the fixed yoke 11.
  • the portion A of the profile of the figure 2 shows the force provided by the actuator 1 to go against the pole springs 5 and thus to crush the movable contacts 21 against the fixed contacts 20.
  • the maximum force provided by the actuator 1 will be different and will be even weaker as the contacts are worn.
  • the force supplied by the actuator 1 becomes weaker since it then consists solely in going against the return spring 4. This effort decreases gradually until the full opening of the contacts.
  • control current which is injected into the control coil 3 when the mobile armature 11 separates from the fixed yoke 10 is therefore representative of the minimum force provided by the actuator 1 to maintain the armature mobile 11 in the closed position and fight against the pole springs 5.
  • the control current measured at this time can be treated to detect the wear of the contacts or to optimize the operation of the device.
  • control means 9 to vary the control current i (t) injected into the control coil 3
  • means 6 to detect the separation of the mobile armature 11 with respect to the breech fixed 10
  • measuring means 7 of the current injected into the coil 3 during the separation of the moving armature 11 relative to the fixed yoke 10 and the processing means 8 of the current i1 measured.
  • the control method can be implemented in the electrical apparatus during a normal opening phase of the contacts or during a phase of maintaining the contacts in the closed position. In the latter situation, it is necessary to open the actuator 1 sufficiently and then to close it immediately before opening the contacts. This operation may for example be performed several times in succession and at regular intervals to enter several current values.
  • the invention thanks to the means defined above, it is therefore a question of progressively lowering the control current i (t) injected into the coil 3 while the moving armature 11 is in the closed position and send a signal Sig to the measuring means 7 to measure the current corresponding to the moment when the moving armature 11 separates from the fixed yoke 10.
  • the force of the actuator 1 controlled by the current level i (t) injected into the coil must be decreased gradually and fast enough not to disturb the operation of the apparatus if the method is implemented during a contact opening phase.
  • the means 6 for detecting the separation of the moving armature 11 with respect to the fixed yoke 10 comprise an electric detection circuit composed of a power source S, a switch, detection means 60 of the opening of the switch and sending a control signal Sig to the measuring means 7 of the current when the switch is open.
  • the detection means 60 of the opening of the switch may comprise for example a resistor and a voltmeter (not shown) for monitoring the voltage across the resistor.
  • a resistor When the voltage across the resistor vanishes, it means that the detection circuit is open and thus the movable armature 11 separates from the fixed yoke 10.
  • the control signal Sig is sent to the means measuring current 7 in the control coil 3.
  • the measured current i1 at the time of receiving the control signal Sig is then processed by the processing means 8.
  • the electrical contact of the switch of the detection electric circuit 6 is formed by the movable armature 11 and the fixed yoke 10.
  • the movable armature 11 is therefore the moving part of the switch of the detection circuit 6 and makes, with the fixed yoke 10, an integral part of the detection circuit 6.
  • the detection circuit 6 is directly connected firstly to the mobile armature 11 and secondly to the fixed yoke 10. When the movable armature 11 is in the closed position, the electrical detection circuit is closed. .
  • an electrical conductor 112 is secured to the movable armature 11 and specific electrical contacts 110 are made at the connection points between the movable armature 11 and the fixed yoke 10 when the movable armature 11 is in the closed position.
  • the detection circuit 6 uses both the movable armature 11 as moving part of the switch but also the return spring 4 as an electrical conductor.
  • the spring 4 is connected to the power source S via a conductive part electrically insulated from the rest of the actuator 1 and for example formed by a copper plate 100 mounted on the fixed yoke of the actuator.
  • the electrical insulation between the copper plate 100 and the fixed yoke 10 of the actuator 1 is for example made by the plastic casing 30 of the control coil 3.
  • the supply source S is thus connected firstly to the fixed yoke 10 of the actuator 1 and secondly to the copper plate 100.
  • the switch 61 inserted in the detection circuit 6 is offset relative to the actuator 1.
  • the switch 61 is for example controllable by magnetic effect.
  • a permanent magnet 101 is placed on the fixed yoke 10 vis-à-vis the switch 61 so as to keep it in the closed state by magnetic effect when the movable armature 11 is in the open position.
  • the movable armature 11 carries a protuberance 111 able to mask the permanent magnet 101 when the movable armature 11 is in the closed position, so as to annihilate the magnetic effect of the permanent magnet 101 on the switch 61 and to cause its opening, for example by mechanical effect.
  • the switch 61 is for example a magnetic micro-switch type MEMS (Micro-Electro Mechanical System). Other configurations using the magnetic effect can be envisaged.
  • the current i1 which is measured by the measuring means 7 may for example be compared by the processing means 8 at different predetermined thresholds recorded in the apparatus to deduce a level therefrom. contact wear or compared to the current measured during the previous operation to follow its evolution. It is also possible to convert the measured current i1 into a percentage of wear and to compare this percentage with different thresholds. Other modes of treatment can of course be considered.
  • the processing means 8 can also determine an optimal control current of maintenance. to apply to the actuator 1.
  • the holding current applied to the actuator 1 is chosen large enough that the movable armature 11 can remain in the closed position regardless of the number of optional additives added to the actuator 1. device, the intensity of the shocks or vibrations experienced by the device or the wear of the device. This current is therefore often chosen more important than necessary to take into account these different situations.
  • the current measured i1 during the separation of the moving armature 11 relative to the fixed yoke 10 can therefore be processed to readjust the holding current and determine an optimum holding current that is adapted to the environment and the configuration of the the device.
  • the current measured during the separation of the mobile armature 11 is for example increased by a determined percentage to ensure that it is sufficient for the maintenance of the armature 11 in the closed position in its environment and in its configuration. Determination of the optimal holding current may be performed at regular intervals to take into account possible additions of additives or environmental change. This functionality can be provided alone in the electrical apparatus or implemented in addition to the wear detection of the contacts. In particular, it makes it possible to optimize the energy consumption of the apparatus by injecting a control current just necessary for maintaining the mobile armature 11 in the closed position.
  • the invention may also be used to detect an uncontrolled opening of the movable armature 11 relative to the fixed yoke 10 and perform an action in response to this opening.
  • the action in response consists in increasing the control current in the coil 3 in order to bring the mobile armature 11 back to the closed position.
  • this functionality can be provided alone in the electrical apparatus or implemented in addition to the wear detection of the contacts and / or the determination of the optimal holding current.
