  • the invention relates to an associated device according to the preamble of patent claim 10.
  • EP 0 694 937 B1 protects the process for recording the change in through-pressure as a replacement criterion for contact erosion.
  • Specific methods for use in switching devices are described in EP 0 878 016 B1, EP 0 878 015 B1 and EP 1 002 325 Bl. It is consistently based on the fact that the pressure changes during the switch-off process, ie when the switch contacts are opened, are recorded by an electromagnetic drive, from which the erosion of the switch contacts is determined and the remaining service life of the switching device is determined therefrom. Based on this, it is an object of the invention to provide a method and the associated device in which, in addition to the contact erosion, the wear of the switching device mechanism can also be taken into account under certain conditions. In addition, it is possible to monitor and control the switch-on movement with the recorded measured values.
  • the changes in through-pressure are now recorded specifically during the switch-on process, i.e. when the switching contacts are closed by the magnetic drive.
  • a position sensor is coupled to the magnetic armature of the magnetic drive in the non-positive contact.
  • the contact erosion can be taken into account as the variable that essentially determines the service life of the switching device, but also the wear of the device mechanism. This can be important if the switching device is specifically a vacuum contactor. While the contact stroke is relatively large (up to 10 mm) for air-riflemen and the play caused by the wear of the moving components of the device mechanics is negligible as a percentage, this can be a not insignificant quantity for vacuum-riflemen.
  • FIG. 1 shows a graphical representation for calculating the contact closing position during the switch-on process
  • FIG. 2 shows a magnetic drive for a switching device with a position sensor

  • FIG. 4 shows an arrangement for a concretized to FIG
  • Figure 5 is a flowchart for arithmetically determining the contact life of a switching device .
  • the method described below for determining the remaining service life of switching contacts essentially consists in the temporal recording of predetermined, discrete positions of a magnet armature of a contactor drive and / or certain components of the switching device drive, and in determining the speed and (average) acceleration of the component to which the position measurement is made, at these predetermined positions.
  • FIG. 1 shows schematically the path-time profile 1 of a component of the switching device, the path of which is identical to the contact path, the path of which is either via a constant constant factor or can be mathematically linked to the contact path via a predetermined function.
  • the position of the closing contact can be determined for the contact closing time t 3 from the determined values of the speed and the acceleration, as well as from the relative positions of the position transmitters to one another and their position times.
  • the still unknown contact closing position between the position x 2 which represents the end of the path interval for determining the speed
  • the position x 4 which lies in the closing direction of the component after the contact closing position
  • the closer the contact interval x 3 can be determined the more precisely the path interval between the positions x x and x is chosen.
  • the positions xi and x should be selected so that they securely enclose the contact closing position, which changes due to wear of the contact and / or mechanics, but the path interval between them does not become significantly larger than the difference between the contact closing positions at the beginning and at the end of the contact life.
  • FIG. It consists in a known manner of, for example, an E-shaped magnetic yoke with magnetic coils and a magnetic armature.
  • an associated switching device is specifically a contactor.
  • This can be an air contactor but also a vacuum contactor, in the latter case the linkage of the drive to the moving contacts of the contactor is more complex.
  • a magnet och 101 on which two solenoids 102 and 102 x sit for magnetic excitation.
  • the pole faces of the magnetic yoke are designated 103 and 103 '.
  • a magnet armature 110 is assigned to the magnet yoke 101, which armature is attracted by the magnet yoke when the magnet drive is excited by the magnet coils.
  • FIG. 1 The full opening position of the magnet armature 110 is shown in FIG.
  • a carrier 130 for a moving contact 141 is arranged on the magnet armature, the carrier 130 being movable in the vertical direction in FIG. 2.
  • the moving contact 141 is brought into the closed position to the fixed contact 151.
  • a position sensor 120 is arranged in frictional contact with the magnet armature 110.
  • the position transmitter 120 essentially serves to record specific positions at the time of the armature movement and is described in detail in the further figures.
  • FIG. 3 shows the magnetic drive with a specific embodiment of a position sensor 120, the advantages of which lie in its simplicity, robustness and the precision in detecting the predetermined positions.
  • the number of positions that can be predetermined in terms of construction can be considerably higher than the minimum number of three positions, ie (i, x 2 and x 4 ).
  • the position transmitter 120 is designed as a cylindrical rod, which is pressed against the magnet armature 110 by a spring 125 with moderate spring force and can be moved in an associated housing.
  • the position transmitter 120 bears against the armature 110, as a result of which, when the armature 110 is switched on, the position transmitter is carried along and acceleration forces act on it, but no impact forces.
  • the cylindrical surface of the position sensor is divided into several conductive and non-conductive surface sections in the axial direction. Since the outer diameter of all surface sections is identical and they adjoin one another without a joint, a smooth cylinder surface is obtained from electrically conductive and non-conductive sections alternating in the axial direction.
  • Such an electrically conductive section can e.g. be a highly conductive, metallic ring, the height of e.g. Can be 1mm or less. The position can be detected by electrically contacting external contact members with this metal ring.
  • the contact can be realized by a rolling contact instead of by a sliding contact.
  • An electrical measuring circuit is connected to this measuring contact, which derives a voltage signal (on / off) from the contact signal (on / off). If, for example, the momentary closing speed of the component is lm / s, the measuring contact supplies the 1 mm as it passes high. Metal ring points in time of the switching edges of the voltage signal, which have a time interval of 1 millisecond. A time signal can therefore be taken from each segment boundary of the surface sections.

  • the moving contacts 141, 141 are movable relative to the fixed contacts 151, 151 ', which are fastened on contact carriers 150, 150', and can be brought into the open or closed position.

  • Contact wear possibly with mechanical wear, gives a current value of the travel (x 3 -x ⁇ ) in switching operation.
  • the wear for example in mm, is given by the difference between the calculated distances (x 3 -x ⁇ ) - (x 3 -x ⁇ ) n eu. In the case of contact burn-off, this difference corresponds to the decrease in through-pressure by reducing the contact piece thickness. If there is also a decrease in pressure through wear of mechanical, power-transmitting parts of the device drive, the mechanical, pressure-related decrease in pressure is included as part of the total decrease in pressure, since the contacts and the drive components are in positive contact during the accelerated switch-on movement.

The difference (x 3 -x ⁇ ) new- (x 3 -x ⁇ ) results in the current change in print through according to position 210. According to position 211, the change in print through is correlated with the end of the service life of the contacts and when the specified conditions are fulfilled according to position 212 Program ended.

This not only optimizes the switching movement, it also minimizes the wear-causing forces on the mechanically moving parts as much as possible.

Abstract

Dans un appareil de commutation, les contacts de commutation sont amenés en position de mise en circuit ou hors circuit par un mécanisme d'appareil de commutation (100), une détente de contact du ressort à force de contact étant produite pour générer la force de contact prédéfinie en position de mise en circuit. La durée de vie d'un tel appareil de commutation est déterminée, d'une part, par une usure des contacts de commutation et, d'autre part, par une usure mécanique du mécanisme d'appareil de commutation. On sait déterminer l'usure des contacts de commutation par détection de la variation de la détente de contact dans l'entraînement de l'appareil de commutation. Selon l'état de la technique, cette mesure se fait toujours lors de la mise hors circuit. Selon l'invention, la variation de la détente de contact est désormais détectée lors de la mise en circuit, ce qui permet de détecter en particulier aussi l'usure mécanique des appareils de commutation. Le dispositif selon l'invention comprend un entraînement magnétique (100) constitué d'une armature (101), d'une culasse (110) et de bobines magnétiques (102, 102') et un capteur de position (120) est couplé à l'armature d'aimant (110) en contact par liaison de force.
