Definitions
- the invention relates to a switching system with a movable contact bridge between two contact points.
- the switching system is provided in particular for high DC voltages, preferably for an HV (DC) relay (high voltage direct current) or for a contactor.
- HV high voltage direct current
- a circuit breaker for DC and AC with two contact points is known. Between the contact points a contact bridge is arranged, which is spent in a triggering of the circuit breaker in the transverse direction. The resulting arcing at the two contact points are driven by means of a blowing device.
- One of the two arcs is in this case blown to an edge region of the contact bridge, whereas one of the bases of the other arc is brought by means of baffles substantially in electrical contact with the two contact points.
- the two contact points are electrically short-circuited by means of the second arc and the second arc assumes the electrical function of the contact bridge in the closed state.
- the second arc is thus connected in parallel to the contact bridge.
- the first of the two arcs goes out.
- the remaining arc is driven by means of another blowing device in a quenching chamber and there extinguished.
- the invention has for its object to provide an improved switching system with a movable between two contact points contact bridge.
- the switching system should, preferably in conjunction with a switch in the form of a relay or contactor, for high DC voltages of z. B. at least 450V and for carrying and separating a continuous current of z. B. at least 250A be suitable.
- This object is achieved by the features of claim 1.
- Advantageous developments and refinements are the subject of the dependent claims.
- the switching system has two contact points and a movable contact bridge arranged therebetween.
- the contact points are thus electrically connected in series and are each formed by a fixed contact and a moving contact, which serve to conduct current, wherein the respective moving contact with the contact bridge is firmly connected and is moved with this.
- the fixed contacts are arranged on approximately U-shaped bent connection rails.
- the contact bridge is rotatable about an axis of rotation, wherein by means of a rotation of the contact bridge about the axis of rotation, the switching system is placed in either a conductive or a non-conductive state.
- the contact points are opened or closed as a result of a rotational movement of the contact bridge, also referred to below as a rotating bridge.
- the axis of rotation is preferably arranged centrally to the contact bridge.
- the contact bridge made of copper or other, electrical current highly conductive material.
- the contacts of the contact points and the connection bars of the fixed contacts suitably consist of the same material as the contact bridge, preferably of copper.
- the arc is ignited by means of the magnetic field of a mag- netic element driven into a quenching chamber.
- the magnetic field is at least partially perpendicular to the propagation direction of the respective arc, by means of which a Lorentz force is exerted on the respective arc.
- the magnetic field within the scarf system is substantially constant.
- the electrical voltage required to maintain the arc is suitably increased to a value which is above the voltage applied to the switching system.
- the switching system is operated in particular by means of direct current, wherein an electrical current flows between the 2A and 500A via its rotary bridge.
- the electrical current is 250A, by means of which the switching system is permanently operated.
- the voltage applied to the switching system is between 30V and 1000V, for example between 450V and 800V.
- the contact bridge is radially movable and / or rotatably connected to a bearing part.
- the connection is suitably indirectly via a rotary bridge support, on which the contact bridge is held.
- the bearing part is in this case rotatable about the axis of rotation, while the rotating bridge carrier is guided in at least one, preferably in two radial, slot-like guide contours of the bearing part.
- two bearing parts and two rotary bridge support are provided between which the contact bridge rests or is held.
- a rotation of the or each bearing member about the axis of rotation causes a transition of the switching system from the closed to the open and thus from the conductive to the non-conductive state.
- the or each rotary bridge carrier is in this case connected rotatably to the bearing part and expediently has a radial bearing clearance relative to the respective bearing part.
- the position of the rotary bridge carrier and thus in particular the position of the contact bridge are thus variable relative to the bearing part and to the axis of rotation.
- the rotary bridge carrier is therefore preferably floating with respect to the bearing part, so it can be transversely or tangentially spent in relation to the bearing part.
- the mobility is comparatively low.
- the rotational mobility of the rotary bridge carrier to the bearing part is smaller than the rotational mobility of the bearing part with respect to the fixed contacts. In this way, it is possible to control comparatively large manufacturing tolerances in the manufacture of the circuit breaker, while still ensuring safe operation. Furthermore, the service life of the circuit breaker is increased because changes in the contacts due to burn or contamination can be compensated by means of the floating suspension.
- a permanent function of the contact bridge which is suitably accommodated by the two electrically insulating and thermally particularly stable rotating bridge carriers, as a result of arranged only indirectly on a rigid axis contact bridge achieved by these is preferably coupled on both sides, each with a rotatable bearing part.
- the coupling is suitably via, preferably on both sides, one spring each.
- the spring is in closed contact points of the switching system - ie in the on state - tensioned (biased) and thus produces a particularly effective contact pressure of the moving contacts on the fixed contacts.
- This spring-loaded floating mounting ensures that even with different contact erosion at the contact points of the contact pressure is always evenly distributed to both contact points and the contacts there.
- An additional realized reserve of the spring force of the or each spring is particularly useful for Abbrandkompensation.
- the springs also referred to below as contact pressure springs, contribute to the acceleration of the contact bridge.
- the radial mobility of the contact bridge with respect to the bearing part is preferably realized in that the respective rotary bridge carrier in at least one, is preferably guided in two radial guide contours of the bearing part.
- bearing elements take on the spring ends of the respective contact pressure spring. These bearing elements are or engage in recesses of the bearing part.
- the recesses are circular arc-shaped and take virtually no leadership function for the rotating bridge carrier in order to avoid overdetermination and thus jamming of the movable rotating bridge carrier relative to the bearing part.
- the respective spring is positioned between two support elements of the bearing part.
- the expediently cylindrical support elements are arranged in the region of the axis of rotation of the bearing part and thus in this respect centrally one behind the other between the guide contours and possibly between the recesses of the bearing part.
- the respective spring which rests between the two preferably integrally formed on the respective bearing part support elements, is bent in this area approximately z-shaped.
- the quenching chamber has a number of radially extending quenching plates.
- the quenching plates are arranged fan-shaped, wherein the distance between two adjacent quenching plates is increased with increasing distance to the axis of rotation.
- two groups of these fan-like arranged quenching plates are formed, wherein between these splitter plate groups are formed on opposite sides free of sheet metal areas.
- a U-shaped connecting rail is preferably arranged in each case and expediently fitted in a radially extending manner.
- the respective connecting rail carries one of the fixed contacts, which form the two contact points together with the moving contacts carried by the contact bridge.
- the voltage needed to maintain an arc formed between the quenching plates increases with increasing distance of the arc from the axis of rotation.
- the resulting at an operating voltage and driven into the quenching arc therefore breaks down when the arc far enough into the quenching chamber and from the axis of rotation is moved away.
- the movement is expediently also carried out by means of the magnetic element. In this way the arc is extinguished.
- the switching system is constructed substantially point- and / or rotationally symmetrical to the axis of rotation.
- the circuit breaker comprises two extinguishing chambers. Due to this construction, the switching system can be safely operated in both current directions, with one of the extinguishing chambers extinguishing the arc which arises during operation in one of the current directions when opening the contact points. In particular, during installation of the switching system in DC operation, an orientation of the circuit breaker must be disregarded.
- the magnetic element has two iron sheets which essentially cover the contact bridge and are arranged such that the axis of rotation is perpendicular to the latter.
- the contact bridge is located in particular between the two sheets. The contact bridge is thus rotatably arranged without one of the sheets restricting this mobility.
- At least one permanent magnet is in magnetic contact. It is expediently the respective permanent magnet either directly in mechanical contact with the sheets or indirectly via another ferromagnetic element, such as an iron rod.
- the permanent magnet magnetizes the sheets such that a substantially constant magnetic field is formed between them. This magnetic field passes through the contact bridge and drives the resulting arcs at an opening of the contact points in the quenching chamber.
- the magnetic element is not rotationally symmetrical, but arranged eccentrically to the axis of rotation at a certain position.
- the magnetic field generated by means of the magnetic element is parallel to the axis of rotation of the contact bridge.
- the arc which arises when the contact points are opened is moved in the radial direction. exaggerated. Any components of the circuit breaker that connect to the contact points along the rotation axis are protected and are not damaged by the arc.
- the bearing part and / or the iron sheets of the magnetic element are not detected by the arc.
- connection of the contact bridge of the switching system to the bearing part can also be independent of the magnetic element and the quenching chamber. Rather, it is considered as an independent invention.
- FIG. 1 is an exploded view of an inventive switching system with a rotatable contact bridge (swing bridge) and with two extinguishing chambers,
- Fig. 3a u. 3b shows a top view of the switching system with closed or opened contacts
- Fig. 4 is a perspective view of a magnetic element of the switching system
- FIG. 5 in perspective, the switching system of FIG. 1 in the assembled state.
- FIGs 1 and 5 the particular for DC and preferably provided in conjunction with a HV relay switching system 1 is shown in an exploded view or in assembled state.
- a not further shown circuit is hedged, wherein two terminals 2a, 3a of the switching system 1 with other elements of the circuit, such as electric cables or the like, are electrically connected.
- the circuit can provide a permanent electrical current of 250A or z. B. also carry a current of 600A for 50ms.
- the electrical voltage, which is applied to the terminals 2a, 3a, in normal operation is between 450V and 800V.
- the terminals 2a, 3a are formed by rail legs of approximately U-shaped bent connecting rails 2, 3, each having a fixed contact 4a in the region of the bend or bend.
- each fixed contact 4a is in each case a moving contact 4b in mechanical and electrical contact, which together form a contact point 4a, 4b.
- the respective further, comparatively short rail limbs 2 b, 3 b of the connecting rails 2 and 3, as well as the comparatively long connecting upper rail limbs 2 a, 3 a, extend approximately radially.
- the moving contacts 4b are supported by a contact bridge 5 made of copper, which is rotatable about a rotation axis 6.
- the contact bridge 5 is inserted on both sides in each case a rotary bridge carrier 7.
- Each rotating bridge carrier 7, which is made of an electrically insulating and thermally comparatively stable material, is connected to a bearing part 8.
- the rotating bridge support 7 take the contact bridge 5 and the bearing parts 8, the rotary bridge carrier 7 between them.
- Each bearing part 8 has substantially centrally, facing away from the rotating bridge carrier 7 a bearing pin 9 a, which engages in a corresponding Lagerausneh- tion 9 b within a housing cover referred to below as a housing cover or a housing half shell 10.
- the bearing pin 9a and the bearing recess 9b together each form a bearing point, by means of which the contact bridge 5 can be pivoted about the axis of rotation 6.
- a cam 11 is attached to each bearing part 8 in its respective edge region, which engages in a coupling rod 12.
- Each coupling rod 12 is guided within a bearing contour 8 facing away from the guide contour or groove 13 of the respective housing part 10, so that a transverse movement of the coupling rod 12 results in a rotation of the bearing part 8 about the rotation axis 6.
- Each housing cover 10 also has a recess 14 which adjoins the respective guide groove 3.
- an iron sheet 15a of a magnetic element 15 (FIG. 4).
- the size of the iron sheets 15a or their dimensions are in this case such that the contact bridge 5 is covered by the iron sheets 15a.
- each quenching chamber 16 Radially to the axis of rotation 6 5 two semicircular extinguishing chambers 16 are arranged around the contact bridge. Between the two extinguishing chambers 16 are two areas 17 without quenching plates (plate-free areas), in which the connecting rails 2, 3 are arranged. Each quenching chamber 16 has a plurality of radially extending and parallel to the axis of rotation 6 extending quenching plates 18. The quenching plates 18 are thus fanned out and the distance between two adjacent quenching plates 17 increases with increasing distance to the axis of rotation 6. The quenching plates 18 and the quenching chambers 16 and the molded connecting rails 2, 3 completely surround the contact bridge 5 in the radial direction, the contact bridge 5 being movable along the quenching chamber 16 by means of the bearing part 8.
- the switching system 1 is substantially cylindrical, wherein the iron sheets 15a and parts of the housing cover 10 form the respective base surfaces. With the exception of both the magnetic element 15 and the coupling rod 12 and the coupling rod 12 associated cam 11, the switching system 1 is substantially rotationally symmetrical to the axis of rotation 6 and point symmetrical to one on the Rotation axis 6 lying point built.
- FIG. 2 the contact bridge 5, one of the rotary bridge carrier 7 and one of the bearing parts 8 are shown in an exploded view.
- the rotationally symmetrical contact bridge 5 comprises four plug-in chamfers or springs 19, two of which are inserted into two receiving openings or grooves 20 of the rotary bridge carrier 7. stuck and there form fit and / or force fit.
- the rotary bridge support 7 has on the side facing away from the contact bridge 5 two guide pins 21 and two bearing elements 22, one of which is visible in each case.
- Each guide pin 21 is seated in the assembled state in a radially extending slot-like guide contour 23 of the bearing part 8 a. Due to the shape of the guide contour 23, the rotary bridge carrier 7 can be displaced relative to the bearing part 8 along a radial bearing clearance in the mounted state.
- the rotating bridge carrier 7 and thus the contact bridge 5 carried by this is therefore floatingly mounted.
- Each bearing element 22 is located in a tangentially extending, curved or curved recess 24 of the bearing part 8 a.
- the bearing element 22 is, in particular centrally, slotted.
- a spring 26 which is designed like a leaf spring and acting as a rotary and contact pressure spring.
- the spring 26 is bent around two raised, cylindrical and arranged in the region of the axis of rotation 8 supporting elements 27 of the bearing part 8.
- the spring 26 is biased in the closed state of the contact points 4a, 4b and thus generates a desired or required contact pressure of the contact bridge 5 on the connecting rails 2, 3.
- the contact bridge 5 In conjunction with the floating mounting of the contact bridge 5 ensures the spring 26 in the on state of the switching system 1, that even with different contact erosion of the contacts 4a, 4b, the contact pressure is always uniformly distributed to the contact points 4a, 4b.
- the spring 26 is bent and thus generates a spring force which drives the rotary bridge carrier 7 in its original position and thus the contact bridge 5 in the closed state. Due to the floating mounting of the rotating bridge carrier 7 or the contact bridge 5 with respect to the bearing part 8, it is possible to allow comparatively high manufacturing tolerances in the production of the switching system 1.
- the contact between the contacts 4a, 4b is maintained until the guide pins 21 rest against the guide contour 23 of the bearing part 8 or the spring 26 is relaxed.
- the contact points 4a, 4b are opened.
- the composite magnetic element 15 is shown in perspective. Between the two mutually parallel iron plates 15a eccentrically an iron rod 15b and this coaxial two permanent magnets 15c are arranged. These are parallel to the axis of rotation 8 and connect the two iron plates 15a magnetically with each other.
- the permanent magnets 15c magnetize both the iron rod 15b and the iron plates 15a, which thus adhere to each other. For mounting the magnetic element 15 therefore no further adhesive or mounting means is required. To increase the stability, however, these can also be glued or screwed.
- the two permanent magnets 15 c are magnetized and arranged relative to one another such that a substantially homogeneous magnetic field 28 is formed between the two iron plates 15 a, the direction of which is parallel to the axis of rotation 8.
- Figures 3a and 3b show the switching system 1 in the closed or opened state.
- the contact state flows via the connecting rails 2 and 3, the contact points 4a, 4b and the contact bridge 5, an electric current.
- the fixed contacts 4a are in direct mechanical and electrical contact with the respective moving contacts 4b (FIG. 3a).
- the bearing part 8 is rotated about the axis of rotation 6 by means of the coupling rods 12 and also the contact bridge 5, and consequently the moving contacts 4b are mechanically separated from the associated stationary contacts 4a. Between them, due to the magnitude of the electric current and the magnitude of the voltage, respectively, a first arc and a second arc formed. The current continues to flow through the switching system 1 due to the arcs.
- the magnetic field 28 generated by the magnetic element 15 causes a Lorentz force on the arcs, so that they are deflected perpendicular to the propagation direction and perpendicular to the magnetic field 28.
- the arcs are comparatively short time away from the contact points 4a, 4b, which protects their contacts from excessive stress and damage. Due to the rectilinearity of the arcs they are moved by means of the magnetic field 28 in the same direction and to the same quenching chamber 16 out. Due to both the continued rotation of the contact bridge 5 about the axis of rotation 6 and the increasing distance of the respective arc to the axis of rotation 6, the length of the first arc is increased.
- the respective arc is driven by means of the magnetic field 28 in the corresponding laminated core of the quenching chamber 16. There, the arc is split into a number of partial arcs between the quenching plates 18. The electrical voltage needed to maintain the current flow through the switching system 1 is thus increased once more.
- the second arc is moved from the side facing away from the first arc of the contact bridge 5 to that side of the switching system 1, on which the quenching chamber 16, within which the first arc is arranged.
- the second arc is accelerated by means of the magnetic field 28 radially outward to this quenching chamber 16. Due to the rotation, the length of the second arc can be shortened or remain constant. The movement in the radial direction causes an increase in its length.
- the second arc will not be further shortened due to the rotation. Rather, its length is increased with increasing distance from the axis of rotation 6.
- the second arc is also split into a number of partial arcs between the quenching plates 18. This and the movement of the partial arcs radially outward by means of the magnetic field 28 and thus an increase in the length of each partial arc lead to the extinction of the individual partial arcs. The flow of current through the switching system 1 is thus interrupted and components of the circuit are protected from overloading.
