Definitions
- the present invention relates to a switching device according to the preamble of independent claim 1.
- a generic switching device has at least one contact point and one of the contact point associated with permanent magnetic arc blowing device.
- the arc blowing device has a first lateral pole plate, a second lateral pole plate, an intermediate pole plate arranged therebetween and at least one first permanent magnet for producing a magnetic blow field.
- the at least one first permanent magnet is in contact either directly or via a magnetic conductor with at least one of the pole plates and is arranged such that a first magnetic field region of the blow field between the first lateral pole plate and middle pole plate, and a second magnetic field region between second lateral pole plate and middle pole plate wherein the magnetic field lines of the first magnetic field region are aligned opposite to magnetic field lines of the second magnetic field region, and wherein the blowing field further comprises a transition region which connects the first magnetic field region and the second magnetic field region.
- the alignment of the magnetic field lines in the transition region is the same, starting from the first magnetic field region and the second magnetic field region, towards the contact point, so that a switching arc arising when the contact point is opened within the transition region depending on the current direction starting from the contact point either in the first magnetic field or passed into the second magnetic field region and blown away in both cases in the same direction from the contact point.
- the three pole plates are aligned substantially parallel to each other.
- two first permanent magnets are provided, wherein the two first permanent magnets are polar opposite to each other.
- the two first permanent magnets can either be assigned to one of the two lateral pole plates or else arranged on the opposite sides of the middle pole plate.
- the two lateral pole plates are connected to the middle pole plate, for example via a magnetic conductor or conclusion.
- the first permanent magnets may be part of this magnetic connection or even form the connecting element between the lateral and middle pole plate.
- a switching device offers the advantage that a bidirectional operation of the switching device is possible, whereby only a single arc of Genlösch adopted is required.
- the switching arc is always blown away from the contact point in the same direction, depending on the current direction-dependent deflection into the first or second magnetic field range, so that the switching arc can be extinguished independently of the current direction in one and the same arc quenching device.
- the required for this purpose arc quenching device can be made arbitrarily and is not the subject of the present application.
- it can be a conventional arc quenching chamber with a plurality of ceramic quenching elements or quenching plates. Since the blower field is generated purely by permanent magnetic, no puffing coils are required.
- the generic switching devices are therefore relatively compact, lightweight and also cost-effective.
- a generic switching device is known for example from DE 10 2015 000 796 A1, from EP 3048626 A1 and from US 2012145675 A1.
- the present invention has therefore set itself the task of further developing a switching device of the generic type such that with a correspondingly larger design of the switching device, a reliable arc running behavior can be ensured. A cost-effective production of the switching device should continue to be possible.
- the invention is solved by the features of independent claim 1. Accordingly, in a switching device according to the preamble of independent claim 1 then an inventive solution to the problem, if the arc blowing device has at least a second permanent magnet as an auxiliary magnet, wherein the auxiliary magnet so in close proximity is arranged to the contact point, that at least a part of the magnetic field of the auxiliary magnet amplifies the blowing field in the transition region.
- the auxiliary magnet fulfills a different function than the one or more permanent magnets.
- the one or more first permanent magnets are associated with at least one of the three pole plates and are therefore in magnetic connection with the corresponding pole plate either directly or via a corresponding magnetic return path. This is not the case with the auxiliary magnet according to claim 1 of the present invention.
- the auxiliary magnet is not in direct contact with any of the three pole plates and is not connected to the pole plates via a corresponding magnetic conductor.
- the function of the auxiliary magnet is to cause amplification of the magnetic field only in the transition region of the magnetic blowing field. This gain is limited to the transition region and does not affect the first or second magnetic field region.
- the auxiliary magnet is arranged to be plane symmetrical with respect to a plane of symmetry of the arc blowing device defined by the plane of extent of the middle pole plate. In this way, a symmetrical amplification of the magnetic field in the transition region is effected. Since the auxiliary magnet is arranged, so to speak, centrally, in particular with respect to contact point and arc blowing device, the amplification takes place in the particularly critical region, namely where the arc arises.
- a magnetization direction of the auxiliary magnet includes a right angle both to the magnetic field lines of the first magnetic field region and to the magnetic field lines of the second magnetic field region.
- auxiliary magnet In the simplest case, only a single auxiliary magnet is provided. However, a plurality of auxiliary magnets may be arranged so as to reinforce each portion of the transition region of the magnetic blowing field.
- the auxiliary magnet can also represent a ring segment and be radially magnetized.
- the auxiliary magnet also be designed such that it amplifies the magnetic blowing field in the entire transition region.
- the auxiliary magnet in this case would be a ring segment which extends over 180 °.
- two auxiliary magnets are provided, wherein the two auxiliary magnets are arranged symmetrically with respect to the plane of symmetry of the blowing device, which is defined by the plane of extension of the middle pole plate.
- a relatively large portion of the transition region can be reinforced by using inexpensive standard permanent magnets.
- the magnetization direction of the two auxiliary magnets to the plane of symmetry in each case includes an angle which is greater than 0 ° and less than 90 °. Further preferably, the angle is in the range between 5 ° and 45 °. Particularly preferably, the angle is in the range between 5 ° and 30 °.
- the contact point has a first contact and a second contact, wherein the first and second contacts are brought into contact with one another upon actuation of the switching device, and wherein the auxiliary magnet is arranged on the side of the first or second contact, which faces away from the other contact.
- the auxiliary magnet can be arranged so that a part of its magnetic field amplifies the blowing field in the transition region, wherein the remaining part of the magnetic field of the auxiliary magnet does not adversely affect the blowing field.
- the contacts are preferably made of a non-magnetic metal, preferably copper. They therefore do not influence the magnetic field of the auxiliary magnet in any way.
- the auxiliary magnet can be firmly connected to the respective contact in a simple manner.
- the auxiliary magnet can be glued or screwed to the corresponding contact.
- the auxiliary magnet is particularly preferably held in a corresponding recess of a housing of the switching device.
- the housing may for example consist of plastic.
- the auxiliary magnet is a rare earth magnet.

- the two fixed contacts 7.1 and 7.2 are each electrically connected to an associated terminal contact 8.1, 8.2.
- the contact bridge 10 is actuated by the armature of an electromagnetic drive 19 and has two movable contacts 9.1, 9.2. When closing the contacts comes the first movable contact 9.1 with the first fixed contact 7.1 to the plant. The second movable contact 9.2 contacts the second fixed contact 7.2.
- the chassis 20 of the switching device, to which the electromagnetic drive is fastened, is identified by the reference numeral 20 in the figures.
- the switching device has an arc blowing device for each of the two contact points in order to blow off the switching arc from the contact point.
- Each of the two arc blowing devices is associated with an arc quenching device 5.1 or 5.2.
- the two arc extinguishing devices 5.1 and 5.2 are arranged on opposite sides of the housing.
- the first arc quenching device 5.1 is assigned to the first contact point 7.1 / 9.1.
- the second arc quenching device 5.2 is assigned to the second contact point 7.2 / 9.2.
- At the top of the housing is also a third arc quenching device
- the third arc quenching device increases the quenching potential as needed.
- Parts of the housing that lie between the arc extinguishing devices can be protected from the arc by suitable copper plates 32.
- All three arc extinguishing devices 5.1, 5.2, and 5.3 each have a plurality of extinguishing elements, which alternately stacked on each other.
- the extinguishing elements are made of ceramic. Alternatively, they can also be designed as quenching plates.
- the structure of the arc blowing device is explained below for the first contact point, consisting of the first fixed contact 7.1 and the first movable contact 9.1.
- the explanation can largely be understood solely on the basis of FIG.
- the blowing field that is generated by the arc blowing device is generated exclusively permanent magnetic in the switching device according to the invention. No electrically operated blower coils are required.
- the two permanent magnets 2.1 and 2.2 shown in FIG. 4 form first permanent magnets in the sense of the claims. They are arranged between the first contact point and the arc quenching device 5.1, which is assigned to the first contact points.
- the first permanent magnet 2.1 is in direct contact with a first lateral pole plate 6.1, which is arranged on a side wall of the switch housing shown in Figure 1.
- the second permanent magnet 2.2 is also in direct contact with a second lateral pole plate 6.2, which is arranged on the opposite side of the housing and shown in Figure 1. Between the two lateral pole plates 6.1 and 6.2 there is a middle pole plate 6.3, which runs parallel to the two lateral pole plates 6.1, 6.2 and is shown in FIG. Between the two permanent magnets and the middle pole plate 6.3 a magnetic yoke is arranged in each case. Both the conclusion and the permanent magnets are cylindrical.
- the two permanent magnets 2.1 and 2.2 are oppositely poled.
- the north pole is located in each case on the outside of the first pole plate 6.1 or on the second pole plate 6.2.
- the common south pole is located at the middle pole plate 6.3.
- the opposite polarity causes the magnetic field established between the second lateral pole plate 6.2 (right) and the middle pole plate 6.3 to be oriented opposite to the magnetic field established between the first pole plate 6.1 (left) and the center pole plate 6.3 , This circumstance can also be seen from the magnetic field lines 23, which are shown in FIG.
- the pole plates define between them two channels, both of which open respectively starting from the first contact point in the arc quenching device 5.1.
- the two channels are interspersed transversely to their longitudinal extent of one of the two oppositely poled magnetic fields.
- the two lateral pole plates 6.1, 6.2 extend laterally next to the contact point, wherein the middle pole plate 6.3 is slightly shorter and ends in front of the contact point. This results in a transition region of the magnetic blowing field at the contact point.
- the magnetic field lines are perpendicular to the magnetic field lines of the two magnetic fields in the channels 4.1 and 4.2. In the transition region, the magnetic field lines are fanned out virtually over an angle of 180 °. The direction of the magnetic field in the channel 4.1 is thereby reversed in the transition region until it finally corresponds to the direction of the magnetic field in the channel 4.2.
- the switching arc 3.1 is produced when the contacts are opened at the first contact point.
- the arc is shown in FIG. 4 (in FIG. 4 the switching arc below the plane of the drawing) is first to the right is deflected and then enters the channel 4.2 between the second lateral pole plate 6.2 and the middle pole plate 6.3.
- the direction of movement of the switching arc 3.1 is illustrated for this case by the arrow 24. If the first connection contact 8.1 is connected to the negative pole of the voltage source, then the switching arc is initially deflected in the opposite direction to the left.
- the switching arc is subsequently driven through the magnetic blow field into the arc quenching device 5.1.
- the middle pole plate 6.3 is also at the opposite end, which faces the arc quenching device 5.1, slightly shorter than the two lateral pole plates 6.1, 6.2.
- the magnetic blower field also has a transition region, shortly before the arc-quenching device 5.1, which conducts the switching arc to the middle of the arc-quenching device 5.1.
- the arc quenching device 5.1 can be kept compact.
- an arc blowing device is also provided which is constructed identically to the arc blowing device at the first contact point.
- the two switching arcs 3.1 and 3.2, which are formed at the contact points 7.1 / 9.1 and 7.2 / 9.2 are deflected in the illustration of Figure 4, depending on the current direction, either first to the right or both to the left, then into the respective arc quenching 5.1 or 5.2 , and subsequently blown into the third arc extinguishing device 5.3.
- the switching arcs 3.1 and 3.2 thus become either through the channels 4.1 or, as shown in Figure 2, driven through the channels 4.2 in the arc quenching.
- the first fixed contact 7.1 is associated with a first arc guide plate 1 1 and the second fixed contact 7.2 is associated with a second arc guide plate 12.
- the first arc guide plate 1 1 and the second arc guide plate 12 extend between the respective fixed contact 7.1 or 7.2 and the respective associated arc quenching 5.1 or 5.2. They each connect the fixed contact 7.1 or 7.2 with the associated connection contact 8.1 or 8.2.
- the first arc guide plate 1 1 and the second arc guide plate 12 are arranged below the respective middle pole plate 6.3 and they extend in width both over the first channel 4.1 and via the parallel second channel 4.2 of the associated arc blowing device. Furthermore, a third arc guide plate 13 and a fourth arc guide plate 14 are provided. The third arc guide plate 13 and the fourth arc guide plate 14 each extend arcuately from the first movable contact 9.1 to the second movable contact 9.2, so that the third arc guide plate 13 and the fourth arc guide plate 14 together with the contact bridge 10 each form a nearly closed loop. As FIG. 2 shows, the middle pole plates 6.3 of the first and second arc blowing devices are each arranged between the third arc guide plate 13 and the fourth arc guide plate 14. The third arc guide plate 13 is located in the illustration of Figure 2 behind the two middle pole plates 6.3 and is therefore shown in phantom in this figure.
- the ends of the third arc guide plate 13 and the fourth arc guide plate 14 are each slightly spaced from the ends of the contact bridge 10, so that the contact bridge 10 can be moved relative to the third and fourth arc guide plate.
- a base of the switching arc jumps from the contact bridge on the third and fourth arc guide plate when the switching arc is blown out of the contact point.
- the corners of the contact bridge are preferably rounded to increase the life.

- the middle pole plates 6.3 of the first and second arc blowers are encased in an electrically insulating manner.
- the contact bridge 10 is arranged on a contact carrier 27 made of electrically insulating material. As Figure 3 shows, the contact carrier 27 extends between the first contact point and the second contact point on the clear width of the housing of the switching device. The contact carrier dips on both sides into corresponding grooves of the housing, so that a barrier of the type of a labyrinth seal is formed for the plasma formed by the arc.
- a bellows 28 is further arranged to avoid a short to ground, which otherwise takes place due to the arc generated by the arc in a flashover of the arc on the yoke plate of the drive of the switching device, if correspondingly high loads are switched.
- each of the two arc quenching 5.1 and 5.2 are assigned and each consisting of the pole plates 6.1, 6.2 and 6.3, advantageously at least one additional Polplattenan ever can be provided, the third Arc quenching 5.3 is assigned and can also be assigned to areas of the two lateral arc quenching 5.1 and 5.2.
- the pole plates of this additional pole plate arrangement preferably extend almost over the entire length of the third arc quenching device 5.3.
- the pole plates 6.1, 6.2 and 6.3 are slightly smaller in this embodiment or end slightly below the third arc quenching device.
- the blowing magnets of the additional pole plate arrangement can be arranged centrally in the region of the third arc quenching device.
- FIG. 5 shows a detailed view of the first contact point of the switch according to the invention shown in FIG. As the illustration shows, is in the immediate vicinity of the contact point Inventor arranged in accordance with provided auxiliary magnet 15, which amplifies the blowing field in the transition region.
- the auxiliary magnet 15 is located on the side facing away from the movable contact 9.1 underside of the fixed contact 7.1.
- the magnetic field lines of the magnetic field generated by the auxiliary magnet are identified by the reference numeral 17.
- only the upper part of the magnetic field actually comes into play, since only this part of the magnetic field influences the switching arc 3.1 which arises at the first contact point 7.1 / 9.1.
- the auxiliary magnet 15 is arranged to be plane symmetrical with respect to a plane of symmetry 16 of the blowing device defined by the plane of extension of the central pole plate 6.3.
- the magnetization direction of the auxiliary magnet 15 includes a right angle to the magnetic field lines of the first magnetic field region 4.1 and to the magnetic field lines of the second magnetic field region 4.2.
- the auxiliary magnet 15 can be firmly connected to the fixed contact 7.1 / 1 1. Possible, for example, a bond or a screw.
- Figure 8 shows a modification in which the auxiliary magnet 15 is received and held in a simple manner in a recess 21 of the housing 18 of the switching device according to the invention.
