Definitions
- the present invention relates to a high current switch according to the preamble of independent claim 1.
- Such a switch comprises a first fixed contact and a second fixed contact spaced from the first fixed contact. Further, a relative to the two fixed contacts movable contact bridge and a feed device are provided to transfer the contact bridge of an open position of the switch, in which the two fixed contacts are not connected to each other, in a closed position in which the contact bridge electrically interconnects the two fixed contacts combines. The feed device is further provided to press the contact bridge in the closed position against the two fixed contacts.
- switches can be divided into two fundamentally different designs.
- the contact bridge is moved during the switching process by means of a suitable feed device on the two fixed contacts until touching the contact surfaces of the fixed contacts and the contact surfaces of the contact bridge and firmly abut each other.
- the contact bridge is usually spring actuated or even formed itself as a spring.
- the dimensioning of the contact bridge influenced just when the contact bridge is designed as a spring, quite significantly the thermally possible continuous current of the switch. If a short-circuit occurs in these switches in the switched circuit, a current with a current intensity which is significantly above the thermally possible continuous current of the switch flows for a short time until the fuse is triggered.
- This process is repeated as long as the current surge persists.
- the heating of the contact points by the arc can lead to a welding of the contacts.
- Particularly critical is the phenomenon of repeated lifting of the contact bridge at spring-actuated contact bridges and contact bridges, which are themselves designed as a spring. If the frequency of the excitation current is in the range of a natural frequency of the spring, then it can lead to a resonance disaster, so that the intermittent incipient arc is maintained for a particularly long time.
- New high-current applications call for switches that allow a continuous thermal current of about 800 amperes and are suitable for surge currents up to 85 kA or more. These requirements are currently only grown so-called blade contact switch.
- a usually wedge-shaped contact blade is pressed into a correspondingly wedge-shaped receptacle of the fixed contact.
- Knife contact switches are often designed so that the knife, so the contact bridge is rotatably connected to one of the two fixed contacts and is pressed only in a corresponding receptacle of the second fixed contact.
- knife contact switches both very high continuous thermal currents and very high dynamic current surges can be switched. Due to the fact that the blade is pressed in during the switch-on process and the contacts are pulled apart during the switch-off process, friction causes relatively high wear. Compared with switches of the former design, blade contact switches have a comparatively short life.
- a switch of the aforementioned type is described in DE 10 2006 008480 B4 as known from the prior art.
- This document also mentions the problem that, in particular at high current pulses and the resulting lifting of the contact bridge to the formation of arcing may occur, both the fixed contacts as also destroy the movable contact bridge.
- the DE 10 2006 008480 B4 therefore proposes to design the contact bridge U-shaped or pot-shaped, wherein the contact bridge in the on state encloses projections of the two fixed contacts projecting at right angles.
- the extensions of the two fixed contacts are resilient and press in the on state from the inside outwards against the cup-shaped contact bridge. Magnetic fields generated by current pulses reinforce the contact pressure between fixed contacts and contact bridge in this design. A lifting of the contact bridge is thus avoided.
- Object of the present invention is therefore to provide a high-current switch, which is suitable for continuous thermal currents of about 800 amps and surge currents up to about 85 kA and at the same time has a long service life.
- a solution according to the invention is the task when the delivery device is designed without a spring, wherein the stiffness of the contact bridge and delivery device in the direction of the pressing force corresponds to a value of at least 50,000 kNmm 2 , and wherein the lowest natural frequency of the system consisting of contact bridge and feed device in the direction of the pressing force is greater than 2000 Hz.
- Contact bridge and delivery device are thus sufficiently stiff to transfer the required high Anpress- forces that prevent lifting the contact bridge at high surge currents with currents up to about 85 kA. Due to the lowest natural frequency of the system according to the invention, consisting of contact bridge and delivery device of at least 2000 Hz, it is ensured that a resonance catastrophe can not occur.
- two movable contact bridges are provided, wherein the two fixed contacts are respectively arranged at one end of the contact bridges between the two contact bridges, and wherein the feed device is adapted to the two contact bridges from an open position in which the two fixed contacts are not connected to each other, to convert into a closed position in which the two fixed contacts are electrically connected to each other by both contact bridges, wherein the contact bridges are pressed in the closed position by the feed device against each other on the fixed contacts.
- the application of particularly large contact forces is possible.
- the two contact bridges are pressed with the same force against the fixed contacts, so that the resulting force on the storage of the two fixed contacts goes to zero.
- the fixed contacts must therefore not be stored very stable in the housing of the high-current switch. Destruction of the switch due to particularly high contact pressure is thus avoided.
- the feed device is dimensioned so that the contact bridge or the contact bridges in the closed position in each case with a force of at least 500 N is pressed onto the two fixed contacts or be. This avoids lifting of the contact bridge at surge currents of more than 35 kA.
- the feed device comprises a spindle drive to transfer the contact bridge or the contact bridges from the open position to the closed position and to press in the manner of a screw on the fixed contacts. This embodiment allows the application of very large contact forces at the same time very simple construction of the high-current switch. In order to generate large contact forces, all kinds of transmissions, for example wedge gears or the like, are also conceivable.
- a spindle of the spindle drive is rotatably mounted on a housing of the high-current switch, wherein the spindle between the two fixed contacts and is arranged perpendicular to the longitudinal extent of the contact bridge or the contact bridges.
- only one spindle is required to produce a uniformly distributed contact force on both fixed contacts. This structure is particularly simple and also allows a cost-effective production.
- the spindle has two opposing threads, wherein the opposing threads are each in engagement with one of the two contact bridges.
- two contact bridges can be brought from an open position, in which the two contact bridges do not touch the fixed contacts, into a closed position in which the two contact bridges each connect both fixed contacts to one another.
- the two contact bridges can move toward one another in a clockwise rotation of the spindle against the fixed contacts, wherein a rotation of the spindle counterclockwise causes the two contact bridges again move away from the fixed contacts.
- the spindle is mounted axially displaceable on the housing under a certain play. This ensures that the two contact bridges are pressed evenly against the fixed contacts. Component tolerances can lead to one of the two contact bridges with axially non-displaceably mounted spindle, the fixed contacts during switching achieved sooner than the second contact bridge. This would mean that a bending moment acts on the fixed contacts, as a result of which the bearings of the two fixed contacts are loaded during each switching operation. This would affect the life of the switch.
- the axial play of the spindle must be smaller be as the travel of the contact bridges between the open position and the closed position.
- At least one sliding guide exists between the contact bridge and the housing of the high-current switch. This ensures that the contact bridges can be safely and easily closed or opened.
- the contact bridge comprises at both ends in each case a 90 ° angled sliding guide element.
- the contact bridge comprises at both ends in each case a 90 ° angled sliding guide element.
- the adjusting device is hydraulically driven.
- very high pressure forces can be achieved.
- a hydraulic feed device is also rigid in the aforementioned sense.
- the high-current switch is an AC switch, wherein the lowest natural frequency of the system consisting of contact bridge and delivery device, in the direction of the pressing force is greater than the AC frequency.
- the AC frequency is in the range of a resonance frequency of the system consisting of contact bridge and delivery device, this system is excited to vibrate. This can lead to a resonance disaster. The result would be a periodic lifting of the contact bridge and the formation of an arc between contact bridge and fixed contact. But if the switch is designed according to the preferred embodiment so that the natural frequency of the system consisting of contact bridge and feed device in the direction of the pressing force is greater than the AC frequency, just this vibration excitation is avoided.
- the contact surfaces of the fixed contacts and the contact bridges are preferably made of silver. Since silver is very soft, a very good surface contact is achieved due to the contact pressure between the fixed contacts and the contact bridge.
- Figure 1 shows a high-current switch according to the invention in an oblique view in a closed position
- FIG 2 shows the high-current switch according to the invention from Figure 1 in open
- Figures 1 and 2 show an embodiment of a high-current switch 1 according to the invention in the closed position ( Figure 1) or open position ( Figure 2).
- the housing 6 of the high-current switch 1 according to the invention is shown partially open to allow an insight into the interior of the switch.
- the switch comprises a left first fixed contact 2 and a right second fixed contact 3.
- the two fixed contacts 2 and 3 are spaced apart from each other in the housing 6 of the switch 1, wherein in each case one end of the fixed contacts 2 and 3 protrudes from the housing 6. At this end there is in each case an electrical connection 9 in order to be able to integrate the switch 1 in the circuit to be switched.
- each of the two contact bridges 4 comprises as a conductor a rectangular copper rod 43, at both ends of which a first contact surface 41 and a second contact surface 42 are arranged.
- the contact surfaces 41 and 42 are designated only in FIG. FIG. 2 likewise shows that the first fixed contact has a contact surface 21 on its end lying in the interior of the housing 6 both on its upper side and on its lower side.
- the right second fixed contact 3 also comprises two such contact surfaces 3.
- the first contact surface 41 of the two bridges 4 is flat on each of a contact surface 21 of the first fixed contact 2 at.
- the second contact surface 42 of the bridges 4 each contacts a contact surface 31 of the second fixed contact 3.
- a spindle 5 Perpendicular to the longitudinal extent of the two contact bridges 4, a spindle 5 is arranged centrally between the two fixed contacts 2 and 3 and is rotatably mounted on the housing 6.
- the spindle 5 is provided to actuate the switch, and move the two contact bridges 4 during the switching on the fixed contacts 2 and 3 and press against each other on the fixed contacts 2 and 3 and the two contact bridges 4 during the turn-off of the two fixed contacts 2 and 3 away.
- the spindle 5 comprises two threaded sections 51 and 52, which in each case engage with one of the two contact bridges 4 via a nut 8 permanently connected to the contact bridge 4.
- the two threaded portions 51 and 52 are designed in opposite directions, so that a rotation of the threaded spindle 5 causes counterclockwise that the two contact bridges in the direction of the two fixed contacts 2 and 3 are moved towards each other. A clockwise rotation of the spindle 5 causes the two contact bridges to move away from each other and the connection of the two fixed contacts 2 and 3 to be released.
- the contact bridges each comprise a sliding guide element 7 at its two ends.
- the sliding guide element 7 is a sheet steel component which is screwed onto the copper rod 43 of the bridge 4 and projects at right angles at the respective end of the contact bridge 4.
- the protruding leg of the Gleit Resultsselements 7 thus extends parallel to the axis of the spindle 5.
- the protruding legs of the Gleit Adjustsetti 7 are guided on Gleit Resultssblöcken 61 of the housing 6.
- the guide surfaces of the slide blocks 61 are also parallel to the axis of the spindle fifth
- the switch 1 according to the invention therefore has a much longer service life than comparable blade contact switches.
- the contact surfaces 21, 31, 41 and 42 are made of silver. Silver conducts very well and is also relatively soft, resulting in a very good contact even with low contact forces between contact bridge and fixed contact.
- the drive of the spindle 5, which may for example consist of an electric motor. By the spindle drive a high contact pressure can be realized even with a low motor torque, with which the contact bridges 4 are pressed onto the inner ends of the fixed contacts 2 and 3.
- the threaded spindle 5 is mounted axially displaceable under a certain play on the housing 6 of the switch 1. As a result, the two contact bridges 4 are pressed uniformly against the two fixed contacts 2 and 3 with the switch closed.
