Definitions

  • the invention relates to a method for determining the burnup of contacts of an electromagnetic switching device.
  • the invention relates to an electromagnetic switching device with a device for determining the erosion of its contacts.
  • From the EP 0 694 937 B1 is a method for determining the burnup and thus the remaining life of contacts in switching devices known in which the measure of the contact erosion so-called contact pressure or through pressure is determined.
  • This pressure is the distance traveled by the armature as an actuator of the switching movement between the beginning of the turn-off, ie the time in which the magnetic armature resting in the end position on a magnetic yoke detaches from this, and the time in which the Differentiate contacts.
  • the timing of lifting of the armature from the yoke is measured with an auxiliary circuit in which the armature and the yoke form a switch which is closed when the armature and magnetic yoke touch.
  • a further auxiliary circuit is required, for example, a complex, galvanically decoupled with the aid of optocouplers from the main circuit auxiliary circuit which detects the occurrence of an arc voltage, which is formed by the forming arc when lifting.
  • the turn-off is used to determine the burn-up or the remaining life
  • the WO 2004/057634 A1 a method and a device for determining the remaining life of a switching device known in which the change in the pressure during the switching, ie when closing the switch contacts by the magnetic drive, is measured.
  • a position sensor is arranged on the armature, which contains at least three positions markings, for example in the form of measuring contacts, with which the time course of the magnetic armature movement can be detected.
  • the position determination of the magnet armature when closing the contacts is determined by calculation from the movement sequence of the magnet armature detected with the aid of these position markers. For this purpose, due to the small number of position marks, a simple algorithm is used on the assumption that between a time before closing the contacts and a Time, which is between the closing time of the contacts and the touchdown of the armature on the magnetic yoke, the anchor acceleration is constant. In practice, however, it has been found that with such an approach, the timing of closing the contacts can be determined only with low accuracy.
  • the invention is based on the object to provide a method for determining the erosion of contacts of an electromagnetic switching device, with an accurate determination of the time in which close the contacts, and thus an accurate determination of the contact erosion is possible.
  • the invention is based on the object to provide an electromagnetic switching device with a device operating according to this method.
  • the object is achieved according to the invention with a method having the features of claim 1.
  • a time characteristic of the relative movement caused by an actuator between the contacts mechanical variable is measured during switching on, and it is by Evaluation of this time course determines the time at which close the contacts, and which is detected by the contacts or the distance traveled by the actuator from this point to its end position distance is at least indirectly detected and compared with a stored reference value.
  • the invention is based on the consideration that the time course of the relative movement is significantly changed at the time of closing the contacts due to the beginning at this time and the movement of the actuator decelerating high spring force of the contact spring, so that with an analysis of the time course of Movement the time of the meeting of the contacts can be safely determined immediately without the need for this an approximation model of the movement, as in the above-mentioned WO 2004/057634 A1 the case is.
  • variable characterizing the movement can be made directly by measuring the speed or the acceleration of one of the contacts or both contacts. Alternatively, the speed of this relative movement causing and with at least one of the contacts mechanically coupled and actuated by an electromagnetic actuator actuator are measured.
  • the time course of the movement is measured with a mechanically coupled to the actuator sensor, whereby the measurement can be done with a measuring circuit which is galvanically decoupled from the switched circuit or the circuit of the magnetic drive.
  • the sensor is a displacement sensor, a speed sensor or an acceleration sensor.
  • the time of the contact closure can be determined particularly easily from its measuring signal. In order to obtain information about the distance covered in this case, their measuring signals must still be integrated simply or twice.
  • FIG. 1 contains an electromagnetic switching device, in the example shown, a contactor, a magnetic yoke 2, on which two magnetic coils 4 are arranged for magnetic excitation.
  • An armature 6 associated with the magnetic yoke 2 is spring-mounted by compression springs 8 in a housing 10 of the switching device which is illustrated only symbolically.
  • Magnetic yoke 2, solenoid 4 and armature 6 form an electromagnetic drive of the switching device.
  • the armature 6 is non-positively connected via a contact spring 12 with a movable contact bridge 14.
  • the movable contact bridge 14 are associated with two fixed contact carrier 16.
  • the magnet armature 6 forms the actuator of the magnetic drive for the relative movement between the contact bridge 14 and the contact carrier sixteenth
  • the contact bridge 14 and the fixed contact carrier 16 are each provided with contact pieces or contacts 18 which have a thickness D 0 in the new state.
  • the switch contact formed by the movable contact bridge 14 and the fixed contact carrier 16 is in open Position. In this switched-off state, the contacts 18 are at a distance S 0 and the pole faces 20 and 60 of the magnetic yoke or the magnet armature 6 are located at a distance H.
  • FIG. 2 now shows a situation in which the contacts 18 touch the first time, the armature 6 has thus covered a distance S 0 .
  • This distance d 0 corresponds to the through-pressure of the switching device in unconsumed contacts 18.
  • the further closing movement of the armature 6 is now against the action of the contact spring 12 and the parallel-connected compression spring 8. Since the spring force exerted by the contact spring 12 is significantly greater than that of the spring 8 exerted spring force, the force acting on the armature 6 spring force increases abruptly and causes a significant change in the course of the closing movement.
  • the force acting on the armature 6 magnetic force is greater than the force exerted by the compression spring 8 and the contact spring 12 spring force, and the armature 6 can continue to move in the direction of the magnetic yoke 2 until finally, as in FIG. 3 is shown, rests in an end or rest position with its pole faces 60 on the pole faces 20 of the magnetic yoke 2.
  • FIG. 4 is now shown a situation in which the contacts 18 are already significantly burned after a plurality of switching cycles, and only have a thickness D 1 ⁇ D 0 . Accordingly, the contact pieces 18 are in the off state at a distance s 1 which is significantly greater than the distance s 0 in the new state.
  • this distance d 1 that is, the through pressure due to the small thickness D 1 of the contacts 18 is significantly reduced compared to the through-pressure in the new state.
  • FIG. 6 is the current flowing through the solenoid current I (curve a) and applied to the solenoid clocked DC voltage U (curve b) plotted against the time t.
  • the solenoid current I curve a
  • U curve b
  • it is a switching device with an example of the WO 2005/017933 A1 is controlled by known methods to adjust the closing speed by which the contacts on the one hand and the poles on the other hand, by controlling the acceleration of the armature. From this figure, it can be seen that the current I decreases steadily until the time t k of closing the contacts in order to rise again at short notice from this point in time t k . This increase is necessary in order to compensate for the suddenly increased spring force acting on the magnet armature from the time t k by a correspondingly higher magnetic force.
  • the path s of the magnet armature (curve e) and its velocity v (curve f) are also plotted against time t.
  • the magnet armature (actuator) is located with its pole faces at a distance H from the pole faces of the magnetic yoke.
  • the velocity v at which the magnet armature moves towards the magnetic yoke increases steadily after a certain time delay with an approximately constant acceleration. The reason for this is the above-mentioned control of the armature movement, which ensures that the speed of the magnet armature does not become too large.
  • Fig. 9 the acceleration b of the armature is plotted against time in a logarithmic scale. It can be seen from the curve g that the acceleration b rises rapidly to an approximately constant value and undergoes a sign change at the time of the contact closure due to the speed drop. This change of sign can be particularly easily recognized in an evaluation of the time course of the acceleration b and used to determine the closing time t k .
  • FIGS. 6 to 9 Diagrams shown are used to exemplify the present when switching an electromagnetic switching device physical conditions.
  • the in FIGS. 8 and 9 shown speed or sign change of acceleration also results when the electromagnetic switching device operated unregulated or by another control method becomes. If, with the aid of a suitable sensor, the speed v or the acceleration is detected either directly by a speed sensor or an acceleration sensor, the closing time t k can be determined particularly easily from the curve of the latter. In principle, the closing time t k can also be derived from a signal measured by a displacement sensor by differentiating it once or twice.
  • FIG. 10 is in a switching device according to the invention to the armature 6 directly a sensor 22 coupled, which may be designed as a speed sensor, acceleration sensor or displacement sensor.
  • a sensor 22 coupled, which may be designed as a speed sensor, acceleration sensor or displacement sensor.
  • the relative movement of the contacts 18 is detected indirectly and evaluated in an evaluation device 25.
  • the time t k is mediated by the change of the acceleration b or the collapse of the speed v.
  • the remaining distance d (through-pressure) or the distance s covered up to this time t k can be removed from the path-time course w (t) of the actuator (armature 6) immediately.
  • the evaluation device 25 can also take over the differentiation or integration of the movement signal generated by the sensor 22.
  • a sensor 24 may be disposed on the movable contact bridge 14.
  • the distances s 0 and s 1 can be measured directly.
  • the speed v can be determined directly as a function of time.
  • the closing time t k is the time when the movement ends and the speed v of the movable contact 18 becomes zero.
  • the sensors 22, 24 are mechanically coupled to the moving parts-armature 6 or movable contact 18. Basically, however, non-contact sensors can be used, the distance of the relevant moving part to a fixed housing part.
  • the distance s 1 known can be concluded by comparison with a stored reference value s 0 directly on the burn D 0 -D 1 and thus also on the remaining life of the contacts.
  • a stored reference value s 0 directly on the burn D 0 -D 1 and thus also on the remaining life of the contacts.
  • the relationship D 0 - D 1 s 1 - s 0 / 0 provided that burnup D 0 -D 1 is evenly distributed between the opposing contacts.
  • the burn D 0 -D 1 can be calculated directly with the above equation, if the distance d 0 (pressure ) is stored as uncommitted contacts as a reference value.
