Definitions
- the invention relates to a switching device for switching an electrical load on a supply network, with a rotary cylinder adjustable in rotation about an axis of rotation, in which a contact bridge is received.
- an electrical load an electrical consumer
- electrical energy it is expediently connected to an electrical supply network.
- the supply network has a number of direct current networks and / or alternating current networks, each of the direct current networks and the alternating current networks forming a so-called supply branch.
- the load if the load is to be operated permanently, it must be supplied from this (first) supply branch in the event of a failure of the supply branch of the supply network connected to it, i.e. if this supply branch does not provide any electrical energy or only insufficient electrical energy to operate the load switched to another (second) supply branch of the supply network who.
- an alternating current network (AC supply branch) connected to the load fails, the load is switched to a direct current network (DC supply branch) for an emergency supply.
- AC supply branch alternating current network
- DC supply branch direct current network
- the load is connected to the supply network by means of a power supply unit.
- a power supply unit typically has a buffer, for example condensate ren, which, in the event of a failure of the supply branch connected to the load, provide sufficient electrical energy to operate the load for a comparatively short period of time, also known as bridging time.
- the bridging time is about 10 ms (milliseconds)
- Mechanical switches can be used to switch the load between two supply branches of the supply network. However, a comparatively long period of time is necessary for switching such mechanical switches, which is typically longer than the bridging time that can be partially realized by means of the network buffer. As a result, the load is not supplied with sufficient electrical energy, for example, so that it cannot be operated reliably or its operation can even be completely interrupted.
- semiconductor switches are used to switch the load between two supply branches. With these, however, there is no galvanic separation of the corresponding supply branch from the load. However, galvanic isolation is necessary for some applications, in particular due to safety requirements, so that these semiconductor switches cannot be used.
- the invention is based on the object of specifying a suitable switching device.
- the switching device should be used to switch a load and / or switch the load between at least two supply branches of a supply network as quickly as possible.
- the switching device has a rotatably adjustable, ie rotatable, rotary cylinder about an axis of rotation.
- the switching device also has an actuator coupled to it.
- the rotary cylinder is preferably designed as a hollow cylinder so that its moment of inertia is as low as possible.
- a first contact bridge is received in the rotary cylinder, which is rotationally fixed with respect to the rotary cylinder.
- a contact also referred to as a contact piece, is arranged each Weil.
- the contact is attached to the respective end.
- the contact is riveted, welded or soldered to the respective end.
- the contacts sit in a respective recess in the lateral surface of the rotary cylinder and protrude beyond the lateral surface, in particular in a radial direction perpendicular to the axis of rotation.
- the recesses are preferably arranged in an opposite position in the rotary cylinder. In other words, the recesses are preferably arranged on a common straight line which is arranged perpendicular to the axis of rotation and runs through it.
- the switching device has a receptacle for the rotary cylinder. This is introduced as a separate part in a housing of the switching device or is preferably integrated into the housing, in particular molded onto it.
- a number of mating contacts are arranged in the receptacle such that two of the mating contacts are electrically connected by means of the first contact bridge or the mating contacts are electrically separated by adjusting the rotary cylinder to a corresponding rotational position (angular position).
- the number of mating contacts thus comprises two mating contacts or more than two mating contacts. So at least two Gegenkon contacts are arranged in the recording.
- two of the mating contacts or, if only two mating contacts are present the two mating contacts are electrically connected to one another in a corresponding rotary position by means of the first contact bridge and electrically (galvanically) separated from one another in a different rotary position.
- one of these two mating contacts is connected to a (first) load connection for the load. So this is the counter contact (on the load side) for connecting the load and the other (network-side) mating contact of the two mating contacts, in particular via an associated supply network connection, provided for connection to the supply network.
- the rotary cylinder is rotated (rotationally adjusted) in such a way that the corresponding mating contacts are no longer electrically connected by means of the first contact bridge, ie are galvanically separated from one another.
- a comparatively reliable separation of the load from the supply network is advantageous due to the galvanic separation.
- the rotary cylinder is rotated (rotatably adjusted) in such a way that the corresponding mating contacts are electrically connected by means of the first contact bridge. He advantageously follows the switching of the electrical load using the rotary adjustment of the Drehzy Linders comparatively quickly.
- a load-side first mating contact and a first mating contact assigned to the respective supply branch are provided for switching the first load connection from a first supply branch to a second supply branch of the supply network for each of the supply branches.
- the number of mating contacts includes the first mating contacts.
- the switching of the first load connection provided for the load from the first supply branch to the second supply branch is brought about by a rotary adjustment of the first contact bridge. Due to the rotary adjustment, the first mating contact on the mains side of the first supply branch is electrically separated from the first mating contact on the load side and the first mating contact on the mains side of the second supply branch is electrically connected to the first mating contact on the load side by means of the first contact bridge.
- the first load connection can be connected to the first or to the second supply branch, so that a corresponding electrical potential is applied there.
- This embodiment of the switching device is used in particular if the two supply networks have the same reference potential, in particular ground, and this is applied to the load.
- a second contact bridge is provided for switching a second load connection provided for the load from the first supply branch to the second supply branch of the supply network.
- the load is switchable and expediently also switched between the first load connection and the second load connection and thus between the first contact bridge and the second contact bridge.
- One of the contact bridges is connected upstream of the load and the other of the contact bridges is connected downstream of the load.
- a second counter-contact on the load side and a second counter-contact on the network side assigned to the respective supply branch are provided for each of the supply branches.
- the second contact bridge is rotationally fixed with respect to the rotary cylinder, in other words the second contact bridge rotates through the same angle and around the same axis of rotation as the rotary cylinder when it is rotationally adjusted.
- the number of mating contacts includes the second mating contacts. Analogously to switching the first load connection from the first supply branch to the second supply branch, the switching of the second load connection from the first supply branch to the second supply branch is effected by a rotary adjustment of the second contact bridge.
- the switching of the first load connection for the electrical load from the first supply branch to the second supply branch or vice versa follows comparatively quickly on the basis of the rotary adjustment of the rotary cylinder first.
- the switching time required for this is less than 5 ms (milliseconds). In particular, it is thus possible to switch the first load connection before the bridging time set out at the beginning has expired.
- the load is intended for connection between the first and the second contact bridge.
- both the first load connection and the second load connection are switched together, that is, synchronously, from the first supply branch to the second supply branch or vice versa. Furthermore, it is thus particularly advantageously made possible to switch the load between a first supply branch designed as a direct current network and a second supply branch designed as an alternating current network or between two alternating current networks or between two direct current networks with different reference potentials.
- the switching device has one or more further contact bridges for this purpose, which are received in at least one further rotary cylinder in a rotationally fixed manner to the first contact bridge.
- both the first contact bridge and the second contact bridge are accommodated in the rotary cylinder, a cylinder intermediate base of the rotary cylinder being arranged between the first contact bridge and the second contact bridge, and the first contact bridge and the second contact bridge, suitably are arranged rotated to one another by 90 ° with respect to the axis of rotation.
- the Zylin are der Eisengeber and the outer surface of the rotary cylinder preferably from an electrically insulating material. Due to the inclusion of the two contact bridges in the rotary cylinder, the two contact bridges are advantageously arranged in a space-saving manner. This aspect represents an independent invention.
- the switching device has two separate rotary cylinders for this purpose, the two rotary cylinders being non-rotatable with respect to one another.
- the first mating contacts and the second mating contacts are arranged in mutually parallel and spaced planes which are oriented perpendicular to the axis of rotation.
- the corresponding contact bridge is expediently arranged in each of the two levels. Unintentional contacting of the first contact bridge with the second mating contacts or the second contact bridge with the first mating contacts is thus avoided.
- first contact bridge With the arrangement of the first contact bridge, the second contact bridge and possibly further contact bridges in mutually parallel and spaced planes, it is also possible to use three phases, for example a neutral conductor being switched by means of one of the contact bridges, or alternatively several loads analogous to the manner shown above Switching.

- the permanent magnet has two, in particular semicircular, sectors, the magnetic polarization of the two sectors being directed in or against a parallel to the axial direction.
- the sectors are preferably arranged with respect to the axis of rotation in such a way that the axis of rotation runs in an imaginary dividing plane between the sectors.
- the permanent magnet is expediently coupled to the rotary cylinder in a rotationally fixed manner by means of a holding element.
- the holding element has a cover which is arranged on the side of the permanent magnet facing away from the coil and at least partially covers this side of the permanent magnet.
- the cover or, alternatively, the entire retaining element is formed from a soft magnetic material.
- This aspect also represents an independent invention. In this way, the magnetic field is guided by means of the cover in the area of the permanent magnet and / or absorption of the magnetic flux through the cover is improved. This advantageously facilitates the displacement of the magnetic field of the permanent magnet when the coil is energized.
- the rotational movement of the permanent magnet and thus of the rotary cylinder thus effected takes place comparatively efficiently in this way and / or the rotation takes place comparatively quickly, that is to say at a comparatively high rotational speed.
- the guidance of the magnetic field in the area of the permanent magnet and / or the absorption of the magnetic flux of the magnetic field to enable a comparatively fast field displacement when the coil is energized are thus further improved.
- the cover is expediently as flat as possible with respect to a direction along the axis of rotation.

- the cover is step-shaped, conical, or hemispherical.
- the expansion of the cover towards the axis of rotation preferably increases.
- the moment of inertia of the folding element is comparatively low and the guidance of the magnetic field is improved.
- the rotational movement of the folding element is limited in both directions of rotation about the axis of rotation.
- This aspect represents an independent invention.
- the first contact bridge is used to make the first counter-contact on the load side with the network-side first Gegenkon contact connected to the first supply branch.
- the other of the load-side first countercontacts with the other of the network-side first countercontact for the second supply branch is by means of the first contact bridge connected.
- the holding element has, according to a suitable embodiment, a (cover) recess in the form of a segment of a circle, in particular with respect to the axis of rotation, with the walls of the cover that limit the cover recess in the direction of rotation when the holding element is rotated.
- a stop for a stop element is preferably arranged, in particular integrally formed, on a housing receiving the holding element.
- the stop element is bolt-like and extends parallel to the axis of rotation.
- the stop element is wedge-shaped and engages in the cover recess in the radial direction.
- the walls are expediently arranged in such a way that the maximum possible angle of rotation between the first end position and the second end position, i.e. between the maximum possible deflections of the retaining element in the directions of rotation, the angular distances between the network-side first mating contacts or the network-side second mating contacts with respect to each other Rotation axis corresponds to se.
- the recess is preferably arranged in such a way that the plane of separation of the sectors of the permanent magnet, which is oriented perpendicular to the permanent magnet, runs between the walls.
- the permanent magnet is automatically pressed against this wall and is advantageously held in a stable manner against an undefined rotary adjustment, in particular not caused by an energization of the coil.
- the coil of the actuator has an inductance less than 0.5 mH (MilliHenry), in particular less than 0.2 mH and / or an ohmic resistance less than 0.5 ohm, in particular less 0.1 ohms.
- a time required for switching is 5 ms or less, so that in the event of a failure of the supply branch connected to it, the load can and expediently be switched to the respective other supply branch without impairing the operation of the load.
- the first contact bridge and / or the second contact bridge are designed as a leaf spring, so that the contacts attached to their ends can be adjusted resiliently in the radial direction. In this way, the contact pressure against the mating contacts is increased and a comparatively reliable electrical contact is achieved.
- the outer surface of the rotary cylinder serves as a stop for the leaf spring, so that the adjustment of the contacts in the radial direction is limited.
- the contact bridges are suitably omega-shaped. In other words, they have a circular arc shape, with wings extending on the outside and essentially concentrically with respect to this being formed on the ends of the circular arc shape.
- the contact bridges are formed from a copper alloy, in particular a copper-beryllium alloy such as CuBe, CuBe 2 .

- the auxiliary spring is arranged on the corresponding contact bridge or preferably joined to it.
- the auxiliary spring has, for example, noses which are received in the slots of the associated contact bridge.
- the auxiliary spring is also firmly attached to the ends of the respective con tact bridge, for example by soldering or welding.
- the receptacle which receives the rotary cylinder has ribs directed radially inward, ie towards the axis of rotation, in which the mating contacts are arranged on the side facing the axis of rotation.
- the ribs of the receptacle are curved towards the axis of rotation. In this way, the pressure of the increases in the course of the rotary adjustment Contact against the rib or against the mating contact arranged in this advantageously comparatively evenly.
- the rotary cylinder is at least slightly braked as it rotates due to the increasing pressure and the associated friction.
- the switching device has a cage-like insulating element with axial struts, that is to say struts extending along the axis of rotation.

These two levels correspond to the (contact) levels that the contacts 28 of the first contact bridge 26 and the second contact bridge 32 have.
- the switching device 2 has a cage-like insulating element 50, the struts 52 of which are arranged with respect to a direction of rotation about the axis of rotation D between the ribs 40 of the receptacle 38.
- an annular (extinguishing) gap 54 with a gap width b which is less than 200 ⁇ m is formed between the rotary cylinder 22 and the ribs 40 and between the rotary cylinder 22 and the struts 52.
- an annular (extinguishing) gap 54 with a gap width b which is less than 200 ⁇ m is formed. Because of such a small gap width b, an arc that may be generated (formed) during a switching process is expanded in the gap 54 to a comparatively large area and is thus cooled. As a result, extinction of the arc is accelerated.
- the insulating element 50 is made of a material, in particular polyoxymethylene (POM), to support the extinguishing of the arc that may be formed during switching, which emits an extinguishing gas when the arc acts on it.
- POM polyoxymethylene
- the first contact bridge 26 and the second contact bridge 32 are designed as an omega-shaped leaf spring, so that the contacts 28 can be adjusted in the radial direction R in a resilient manner.
- a contact pressure (contact pressure) of the contacts 28 on the mating contacts 42, 42 ', 44, 44', 46, 46 ', 48, 48' is increased and a comparatively reliable electrical contact is realized.
- the first contact bridge 26 and the second contact bridge 32 each have two slots 56, which extend from the ends of the respective contact bridge 26 and 32 in a spanned by means of this and perpendicular to
- Rotation axis D run oriented plane. Due to the slots 56, two bridge legs 58 running parallel to one another are formed at each end of the respective contact bridges 26 and 32, one of the contacts 28 being arranged on each of the bridge legs 58. So on one of the bridge legs 58 one of the contacts 28 and another of the contacts 28 on the other bridge leg is arranged. Consequently, there is a uniform contact pressure of the contacts 28 against the mating contacts 42, 42 ', 44, 44', 46, 46 ', 48, 48' even in the case of ribs 40 and / or the mating contacts 42, 42 ', 44 which are uneven along the axis of rotation D , 44 ', 46, 46', 48, 48 'allows.
- an auxiliary spring 60 is provided for each contact bridge 26 and 32, which the ends of the respectively assigned con. clock bridge 26 or 32 with a force applied in the radial direction R with an additional spring.
- the auxiliary spring 60 is also omega-shaped and con centric to the associated contact bridge 26 and 32 arranged and attached to this.
- the auxiliary spring 60 has lugs 62 which are received in the slots 56 of the associated contact bridge 26 and 32, respectively.
- the ribs 40 also have a curvature towards the axis of rotation D (cf. also FIGS. 8a and 8b). In other words, the distance in the radial direction R at the end of the respective rib 40 with respect to a direction of rotation about the axis of rotation D is greater than in a central (central) region of the rib 40.
- the actuator 18 of the switching device 2 has a disk-shaped permanent magnet 64 extending perpendicular to the axis of rotation D, which is coupled (connected) to the rotary cylinder 22 in a rotationally fixed manner by means of a holding element 66, cf. in particular Figures 2, 3, 6a and 6b.
- the intermediate cylinder base 34 formed on the lateral surface 24 of the rotary cylinder 22 has a screw receptacle 68 for a screw 70, by means of which the rotary cylinder 22 is screw-fastened to the holding element 66.
- the holding element 66 is rotatably mounted in the housing 36 by means of bearings 72.
- the actuator 18 also has a coil 74. This is used to generate a magnetic field which, due to the interaction with the magnetic field of the permanent magnet 64, a rotational adjustment thereof and due to the coupling of the rotary cylinder 22 with the contact bridges 26 and 32 received therein acts.
- the permanent magnet 64 has two semicircular sectors 76, the magnetic polarization of which is directed essentially opposite to one another and directed parallel to the axis of rotation D.
- a parting plane T of the two sector Ren is parallel to the axis of rotation D, the axis of rotation D being arranged in the parting plane.
- the axis of the coil 74 extends perpendicular to the axis of rotation D.
- the coil 74 comprises a soft magnetic core 75, at both ends of which a pole piece 77 made of a soft magnetic material with a (magnetic pole) surface oriented parallel to the permanent magnet 64 is arranged.
- the holding element 66 has a cover 78 formed from a soft magnetic material for the permanent magnet 64.
- the cover 78 is arranged on the side of the permanent magnet 64 facing away from the coil 74 and partially covers this side in an (axial) direction parallel to the axis of rotation D.
- the holding element 66 and in particular its cover 78 serve to guide the magnetic field in the area of the permanent magnet 64, so that when the coil 74 is energized, a comparatively fast field displacement of the magnetic field of the permanent magnet 64 occurs, which results in a comparatively fast rotation of the permanent magnet 64 .
- the expansion of the cover 78 in the axial direction is less than that of its expansion in the radial direction.
- the cover 78 is as flat as possible with respect to a direction along the axis of rotation and its moment of inertia is reduced.
- the cover 78 is designed in steps.
- the expansion in the axial direction towards the axis of rotation D increases. At most, their expansion in the axial direction, that is to say parallel to the axis of rotation D, is selected in such a way that sufficient absorption of the magnetic flux for the rotary adjustment can be achieved.
- the permanent magnet 64 also has a notch 80 as an assembly aid. This is arranged in the parting plane T of the two sectors 76.
- the coil 74 has an inductance of less than 0.5 mH and / or an ohmic resistance of less than 0.5 ohm. This enables a comparatively rapid increase in a coil current. Consequently, one is correspondingly faster Increase in the field strength of the magnetic field generated by the coil when it is energized, and thus a correspondingly rapid rotational adjustment of the permanent magnet with the contact bridges 26 and 32 coupled to it in a rotationally fixed manner.
- the control unit 20 has capacitors (not shown further) and connected to the coil 74, by means of which the coil current can be provided in a correspondingly short time.
- the cover 78 has two with respect to the axis of rotation D opposite and circular segment-shaped cover recesses 82.
- the walls 84 of the cover 78 delimiting the cover recess 82 in the respective direction of rotation act at a stop for a wedge-shaped stop element 86 formed on the housing (FIG. 7). This protrudes in the radial direction R between the walls 84. In this way, a rotational movement of the holding element 66 and thus of the contact bridges 26 and 32 in both directions of rotation about the axis of rotation D is limited.
- the walls 84 are arranged in such a way that the maximum possible angle of rotation of the holding element 66, here 45 °, between the end positions, i.e. between the maximum possible adjustment positions (deflections) of the two directions of rotation, the angular distances between the first mating contacts 44 and 44 on the network side 'and the network-side second mating contacts 48 and 48' to each other be with respect to the axis of rotation D corresponds.
- Figures 8a and 8b show schematically the switching device 2 in a cross section, the cutting plane running perpendicular to the axis of rotation and through the first mating contacts 42, 42 ', 44, 44'. Accordingly, the second Ge counter contacts 46, 46 ', 48, 48' are arranged outside this cutting plane. For the purpose of better understanding, these mating contacts 46, 46 ', 48, 48' are shown in dotted lines.
- the position of the first contact bridge 26 is corresponding to the first end position with respect to the corresponding direction of rotation about the axis of rotation D, in which end position further rotation in this direction of rotation by means of the stop element 86 is prevented.
- the first mating contact 44 assigned to the first supply branch 6 and the first mating contact 42 on the load side are electrically connected to one another.
- the electrical connection of the two first mating contacts 42 and 44 is separated.
- the first contact bridge 26 shows the position of the first contact bridge 26 corresponding to the second end position with respect to the corresponding direction of rotation about the axis of rotation D.
- the first contact bridge 26 is used to connect the first mating contact 44 'on the network side assigned to the second supply branch 10 and the first mating contact 42 on the load side 'electrically connected to each other.
- the electrical connection of the two first mating contacts 42 'and 44' is separated.
- the switches 16 are each formed by means of the first contact bridge 26 and the second contact bridge 32 and the contacts 28 arranged at their ends, so that with a corresponding adjustment position by means of the first contact bridge 26 and by means of the second contact bridge 32, the network-side counter contacts 44, 44 ', 48, 48' and the corresponding load-side mating contacts 42, 42 and 46, 46 'are connected to one another.
- FIG. 8c An alternative embodiment of the switching device 2 is shown in FIG. 8c.
- the switching device 2 only has a first network-side opposite contact 44 and a first mating contact 42 on the load side, which can be electrically connected by means of the first contact bridge 26.
- the above dargestell th statements apply analogously to this embodiment of the switching device 2.
- the rotational movement of the holding element 66 is limited in such a way that in one of the end positions the first network-side mating contact 44 and the load-side first mating contact 42 are connected to one another by means of the first contact bridge 26. In the other end position, the two mating contacts 42 and 44 are galvanically isolated from one another.
