Definitions

  • the invention relates to magnet armatures, e.g. B. Magnetic armature for electromagnetic contactors, contactors with magnetic armature and method for switching a contactor.
  • a magnetic armature In electromagnetically operated contactors, a magnetic armature is generally a moving part that can electrically connect two electrodes by moving a contact stamp. Contactors are used to switch strong electrical currents and/or high electrical voltages, possibly in a protective gas atmosphere. The immediate processes of closing or opening the switch and the arcs that occur in the process represent a great stress when high electrical power is to be switched, particularly for the material of the electrodes and the contact stamp. The risk of these electrical contacts sticking increases with the number of switching operations.
  • the magnet armature comprises a first spring element with a first spring stiffness k1, a second spring element with a second stiffness k2, a rest position, an end position and a middle position which is located between the rest position and the end position.
  • the first spring element is intended to be elastically deformed during a switching process during the transition from the rest position to the middle position, but not during the transition from the middle position to the end position.
  • the second element is intended to be elastically deformed during the transition from the middle position to the end position, but not during the transition from the rest position to the middle position.
  • the rest position, the middle position and the end position represent positions of the magnet armature relative to its surroundings, e.g. B. within an electromagnetic switch.
  • the middle position does not necessarily have to be the same distance from the rest position as from the end position.
  • the rest position indicates the position in which the magnet armature is when no magnetic force is acting on it.
  • the end position indicates the equilibrium position when the magnetic force intended to close a switch acts on the magnet armature and the electrical contact to be closed is permanently closed.
  • the first stiffness k1 of the first spring element and the second stiffness k2 of the second spring element can be different.
  • the fact that the magnet armature moves against the restoring force of the first spring element when moving from the rest position to the middle position and against the spring force of the second element when moving from the middle position to the end position can reduce the switching time.
  • the spring stiffness k1 of the first spring element is less than the spring stiffness k2 of the second spring element, the magnet armature works against a smaller resistance force when tightening, so that greater acceleration and thus a shortening of the switching time is achieved.
  • the restoring force of the second spring element essentially causes rapid opening when the magnetic force on the magnet armature (i.e. when opening the switch) is eliminated.
  • a magnetic armature is therefore specified which experiences a non-linear resistance force when closing and opening. Rather, a magnet armature is specified, the resistance force acting on it can increase successively due to different spring stiffnesses.
  • first spring element and the second spring element are arranged in series.
  • spring elements When spring elements are arranged in series, there is a resulting spring stiffness of the combination of the two springs, the reciprocal of which corresponds to the sum of the reciprocals of the individual spring stiffnesses.
  • Two spring elements arranged in series therefore behave like a single spring element with the corresponding one Replacement stiffness.
  • additional technical precautions are required, e.g. B. mechanical stops and / or applying a spring preload to individual spring elements and / or the provision of a displaceable bushing, as described below, is necessary.
  • the magnet armature additionally comprises a bushing which is arranged between the first spring element and the second spring element.
  • the socket can touch the one end of the first spring element directed towards the socket and the one end of the second spring element directed towards the socket.
  • the magnet armature additionally includes a cylindrical section.
  • the first spring element, the bushing and the second spring element surround the cylindrical section - or each have their own cylindrical section with possibly a different radius - coaxially.
  • the end of the first spring element pointing towards the socket is intended to move relative to the cylindrical section during the transition from the rest position to the middle position, but not during the transition from the middle position to the end position.
  • the bushing and the end of the second spring element pointing towards the bushing are intended to move relative to the cylindrical section during the transition from the middle position to the end position, but not during the transition from the rest position to the middle position.
  • the distance h from the rest position to the end position is the full stroke that the magnet armature covers when activated in order to connect two electrodes of a contactor with a contact stamp.
  • the stroke h can be, for example, 2 mm.
  • the middle position can be in an interval between 40% and 60% of the full stroke h.
  • the spring stiffness of one of the two spring elements is approximately 3.3-3.6 times the spring stiffness of the other.
  • the second spring element can have the higher spring stiffness: 3.3 ⁇ k2/k1 ⁇ 3.6.
  • the spring stiffness of the first spring element is between 0.5 N/mm and 0.9 N/mm.
  • the stiffness of the second spring element can be between 2.3 N/mm and 2.7 N/mm.
  • the magnet armature may further comprise a contact stamp and/or a magnetizable material in addition to at least one cylindrical section.
  • the contact stamp is arranged at one end of the area of the armature with the one or more cylindrical sections.
  • the optional magnetizable material may be located at the opposite end.
  • the contact stamp comprises an electrically conductive material and is intended to connect two electrical contacts in the end position of the magnet armature.
  • the magnetizable material may include or consist of iron, cobalt and/or nickel. Via the magnetizable material, the magnet armature can interact magnetically with its surroundings (e.g. an adjacent magnetic coil in a yoke), in particular to enable displacement between the three positions, i.e. H. a
  • the cylindrical section has a first section and a second section.
  • the first section has a first diameter and the second section has a second diameter.
  • the cylindrical section and thus the diameter has a step.
  • the step between the two sections represents a stop for the bushing, which is referred to below as the magnet armature stop.
  • the bushing touches the magnet armature stop when moving from the rest position to the middle position (MP), but not when moving from the middle position to the end position.
  • a contactor can include a magnet armature as described above with a socket between the two spring elements, a yoke with an integrated coil and a guide with a first mechanical stop.
  • the magnet armature and the yoke form an electromagnetic actuator intended to move the magnet armature relative to the yoke and the guide. In positions between the rest position and the middle position, the bushing does not touch the first mechanical stop. In positions between the middle position and the end position, the bushing touches the first mechanical stop.
  • the middle position is therefore defined as the position from which the bushing touches the stop during closing. From the rest position to the middle position, the first spring element essentially counteracts a closing force: If the magnet armature moves from its rest position to the middle position, the first spring element is essentially compressed. The second spring element can be subjected to a preload that is greater than the tension on the first spring element in the middle position. This will make the second spring element Transition from the rest position to the middle position is not compressed.
  • the contactor in the yoke includes one or more coils that can generate a magnetic field and, together with the magnetizable material of the armature, form an electromagnet.
  • the contactor can further comprise a cavity in which the contact stamp on the magnet armature and two electrodes spaced apart from one another are arranged.
  • the cavity can be filled with a gas, e.g. a noble gas.
  • the distance between the electrodes and the contact stamp is preferably smaller than the total stroke h of the magnet armature.
  • the magnet armature can also have another spring element that can compensate for manufacturing tolerances in the distance between the electrodes and the contact stamp and generates the actual contact force. This is particularly important when the material of the electrodes or the contact stamp is worn away by repeated switching operations at high electrical power.
  • the electromagnet of such a contactor can be operated with an operating voltage of 12 V, 24 V, 48 V or any other voltage available.
  • the contactor can have a cavity, e.g. a cavity filled with an inert gas in which the contacts to be switched are located.
  • a cavity e.g. a cavity filled with an inert gas in which the contacts to be switched are located.
  • the service life which is increased by the non-linear counterforce, can be further increased by the gas filling in the cavity.
  • the contactor has a guide with a third stop.
  • the third stop can represent a limitation for the movement of the magnet armature.
  • the magnet armature can touch the third stop in its rest position.
  • the third stop can in particular absorb the force of the first spring in the rest position.
  • the position of the third stop therefore determines the position of the magnet armature relative to the guide in the rest position, a defined rest position.
  • the cylindrical section should have the mechanical magnet armature stop, which can be achieved as described above by two different diameters on the cylindrical section and the corresponding step. This allows the second, e.g. stiffer, spring element to be dimensioned independently of the first, e.g. softer, spring element and to be connected via the bushing and the mechanical Magnetic armature stop with defined preload must be installed.
  • the ratio of the spring rates is not limited.
  • the numerical values depend on the size, among other things, and are only intended as examples.
  • a series connection of the two spring elements is possible but not mandatory.
  • the mechanical stops in particular the first stop and the magnet armature stop, can decouple the springs.
  • a method for switching an electromagnetic contactor which has an electromagnet, a contact stamp, a first spring element and a second spring element, is defined according to claim 11.
  • Figure 1 shows the cross-section of a magnetic armature MA in its rest position RP.
  • the magnetic armature MA has a first spring element F1 and a second spring element F2.
  • the two spring elements F1, F2 determine the restoring forces during the transition from its rest position to its end position.
  • the first spring element F1 determines the restoring force during the transition from the rest position to the middle position.
  • the restoring force during the transition from the middle position to the end position is determined by the spring stiffness of the second spring element F2.
  • h1 is the length of the path covered during the transition from the rest position to the middle position.
  • Figure 1 shows, in addition to the magnet armature MA, a guide FÜ which limits the movement of the armature to a displacement along an axis when moving between the positions.
  • the guide FÜ can thus represent a guide rail with a first stop A1.
  • a bushing B is arranged between the first spring element F1 and the second spring element F2.
  • the magnet armature MA has a cylindrical section ZA.
  • the first spring element F1, the second spring element F2 and the bushing B are arranged coaxially around the cylindrical section ZA.

  • the second spring element F2 is not compressed or is only compressed insignificantly during the transition from the rest position RP to the middle position MP.
  • the bushing B moves by the distance h1 until the bushing B hits the first stop A1.
  • the restoring force acting on the magnet armature MA is essentially or exclusively determined by the spring stiffness of the first spring element F1.
  • Figure 2 shows the magnet armature in its middle position MP.
  • the socket B touches the first stop A1. If the magnet armature is moved further to the left relative to the guide FÜ, the bushing B is supported on the first stop A1, so that the first spring element F1 cannot be compressed any further. During further movement, the second spring element F2 is inevitably compressed.
  • the magnet armature is now in a position in which an electrical switch belonging to the magnet armature is closed by touching the contact stamp of two electrodes.
  • a magnet armature which enables both quick closing and quick opening and which, in particular, reduces the burning time of an arc that occurs and the risk of the contacts sticking.

  • Figure 5 additionally shows a cavity HR, in which ends of a first electrode and a second electrode face the contact stamp KS.

  • a gas in the HR cavity e.g. B. a noble gas, in order to extinguish an arc as quickly as possible, especially when opening the contact, in order to protect the material of the electrodes and the contact stamp KS.
