Definitions

  • the invention relates to an electromagnetic drive for a switch, in particular in the field of medium voltage technology, with at least one magnetic body which defines an air gap, arranged in the air gap the magnet body movably guided moving part, at least one permanent magnet and at least one conductor can be acted upon with electricity is at least partially disposed in the air gap, wherein the one or more conductors extend at a movement of the moving part at least partially in a magnetic flux generated by the or from the permanent magnets / extend.
  • Such an electromagnetic drive is for example from the DE 198 15 538 A1 known.
  • the disclosed there drive has a three-phase linear motor, which is composed of several motor modules.
  • the motor module has a certain number of fixed motor coils and in this regard longitudinally movably guided moving parts with permanent magnets.
  • the excitation of the motor coils creates a magnetic field in which the permanent magnets of the moving part are arranged.
  • Due to the Lorenzkraft generated there is a drive movement of the moving part, which is connected via a switching rod with the moving contact of a switch. To switch on the vacuum switch, the moving contact is pressed by the three-phase linear motor against a fixed contact of the switch, wherein the moving part reaches an end position.
  • an electromagnetic drive which is a frame-shaped closed yoke having soft magnetic material which is stacked to avoid eddy currents from lamellae.
  • the yoke forms a cavity in which an existing of soft magnetic material anchor is movably guided between two end positions. In each end position, the armature contacts the soft-magnetic yoke with one of its end faces, an air gap being defined between the other end face of the armature opposite the contact point and the closed circumferential yoke.
  • In the cavity of the yoke further two coils are fixed, each surrounding one of the end faces of the armature. Between the coils permanent magnets for generating a magnetic flux are provided.
  • the anchor Due to the air gap, the anchor remains fixed in the respective end position. Due to the excitation of the coil, which encloses the air-gap side end, in the air gap, a high magnetic flux is generated that demolished to reduce the magnetic resistance of the armature yoke and is transferred with closure of the air gap in its second stable end position in which he with its other end face, which previously limited the air gap, rests against the yoke. The exciting current of the coil can now be interrupted, since the armature is fixed in this end position.
  • the two prior art magnetic drives described above are based on different physical effects.
  • the electromagnetic drive according to the DE 198 15 538 A1 uses the so-called Lorentz force to generate the driving effect, which arises when moving charged particles in a magnetic field.
  • the effect of an electromagnetic drive according to the WO 95/07542 is due to the physical effect that a magnetic field preferably in a material with a high magnetic permeability or, in other words, propagates in a material having a low magnetic resistance.
  • a magnetic field preferably in a material with a high magnetic permeability or, in other words, propagates in a material having a low magnetic resistance.
  • the entire system is converted from an energetically unfavorable state with a high magnetic potential into an energetically more favorable state in which an air gap is closed and the magnetic flux passes almost exclusively through a material with low magnetic resistance.
  • the power to transfer the system into the energetically favorable state results from the formation of gradients.
  • Drives based on such an effect are also called reluctance
  • Electromagnetic actuators based on the Lorentz force have a high dynamic and can moreover be controlled in a simple manner, namely via the current conducted through the magnetic field.
  • springs, pawls or the like are usually used, the force effect is to be lifted only with effort.
  • Reluctance drives are usually characterized by a stable end position fixation. However, they are liable to the disadvantage of a highly non-linear path-force curve, which can either be difficult or at the expense of the holding force in the end positions or at the expense of space can be influenced.
  • the electromagnetic drive shown there has a gap limiting magnetic body with a permanent magnet.
  • the magnetic field of the permanent magnet passes through an air gap into which a locking body connected fixedly to the moving part extends.
  • the magnetic field of the permanent magnet is guided via the locking body and the moving part instead of over the air gap, wherein, however, a new magnetic circuit is formed.
  • a coil is further arranged, which serves to weaken the magnetic field of the permanent magnet, so that the moving part between contact position and separation position can be moved back and forth.
  • the object of the invention is to provide an electromagnetic drive of the type mentioned, which can be fixed in its end positions in a simple manner, but the simple control of the drive movement is maintained.
  • the invention achieves this object by virtue of the fact that the moving part is fixedly connected to at least one soft-magnetic locking body and that the magnetic flux generated by the permanent magnet (s) passes through the locking body in an end position of the moving part, the air gap being bridged by the magnetic flux locking body ,
  • the electromagnetic drive according to the invention makes use of both the Lorentz force and the force effect resulting from a reduction of the magnetic resistance or, in other words, the reluctance force.
  • an air gap is bridged in at least one end position by the locking body, which increases the magnetic resistance for the magnetic flux.
  • the moving part has thus taken an energetically favorable state. After detaching the locking body from its end position, the magnetic flux is forced to flow over the air gap provided in the magnetic body or via air gaps formed and enlarged between the magnetic body and the locking body, thereby increasing the magnetic resistance. In this way, a magnetically unfavorable state is set with regard to the end position. The result is a counteracting the detachment magnetic force.
  • the moving part can be connected via a suitable mechanism, such as drive rods and power transmission lever, with a movable switching contact of a switch, in particular a vacuum switch.
  • a suitable mechanism such as drive rods and power transmission lever
  • the movable switching contact is firmly in contact with a fixed contact piece of the switch.
  • the force effect due to the reduction of the magnetic flux for the magnetic flux has a highly non-linear characteristic, since high forces are generated at small distances of the locking body from the magnetic body.
  • middle position in which the locking body is further spaced from the yoke, the drive is almost exclusively Lorenz concept.
  • the electromagnetic drive according to the invention can therefore be controlled in the middle positions of the moving part in a simple manner, namely either via appropriate power supply of the conductor or by changing the magnetic flux generated electromagnetically by means of coils.
  • a sufficiently high locking force is provided at the same time in order to avoid the lifting of a movable switching contact from a stationary mating contact even in the event of a short circuit.
  • the locking body it is by no means necessary for the locking body to bear against the areas of the magnetic body or the magnetic body delimiting the air gap. Rather, the locking body can be held with a small distance to these areas, so that in these cases, for example, a permanent Antikskraft for the switching contact against the fixed contact of the switch can be generated. It is essential, however, that the magnetic resistance in the end position is minimized compared to other possible paths.
  • permanent magnets are attached to the moving part, and the magnetic flux generated by them and possibly also the conductor generated by the conductor partially flows over the locking body in an end position of the locking body, so that the resistance of the entire magnetic circuit in the end position is minimized.
  • the moving part has at least one coil with a carrier, which is wrapped by the conductor, wherein each locking body is connected to an end face of the coil.
  • the electromagnetic drive is a lifting drive, wherein the stroke of the electromagnetic drive corresponds to the length of the coil or coils substantially.
  • the locking body may be arranged on one side or on both sides of a coil. If the moving part has, for example, two locking bodies and a coil, it is fixed in two end positions. The influence of the locking body on the force-displacement characteristic of the drive is increased compared to the variant with a locking body.
  • the magnetic body comprises in addition to the permanent magnet or magnets, a soft magnetic yoke, wherein the magnetic flux generated by each permanent magnet passes through the yoke.
  • the use of a yoke to guide the magnetic flux helps to reduce costs because the air gap does not have to be placed in a large and therefore expensive permanent magnet. Rather, the use of a smaller permanent magnet is sufficient.
  • the yoke is advantageously annular or frame-shaped, wherein by the example rectangular frame, a magnetic circuit is formed, the only is interrupted by an interrupting the frame course air gap. To avoid eddy currents, the yoke is composed of lamellae in batches. The magnetic body and thus the one or more permanent magnets are stationary with respect to the moving part.
  • this development of the invention is also referred to as a drive based on the Tauchspulenzin.
  • Such a drive is compared to drives on the three-phase linear motor principle with a DC voltage, which can be obtained from only one phase of a three-phase network.
  • each locking body abuts in the end position associated with it on the soft magnetic yoke. An air gap between the locking body and the magnetic body in the end position is thus avoided. The magnetic flux passes from the magnetic body directly into the locking body, whereby the magnetic resistance of the magnetic circuit is minimized. The moving part is thus firmly locked in the end position.
  • a spring is provided for detaching the moving part from its end position.
  • the holding force in the respective end position can be reduced or even eliminated by a suitable energizing of the coil.
