Definitions

  • the invention relates to a switching mechanism for an electrical load switch, with a switching behavior of the switching contacts of the switch which is independent of the actuation of an actuating means of the switching mechanism, the actuating means interacting in a movement-locking manner with a driver element which interacts via a freewheel with a switching element that triggers the actual switching process.
  • Electrical load switches especially those with fuses, are used, for example, in industry and power plants as both busbar feed switches and outgoing switches for switching highly inductive loads (e.g. motors) including overload.
  • highly inductive loads e.g. motors
  • the actuating means is designed as a shift lever which cooperates with a shift sleeve in a rotationally fixed manner and can be pivoted over a pitch circle.
  • a selector shaft interacts positively with play in the circumferential direction with the switching socket, and a spring support interacts positively with play in the circumferential direction with the switching sleeve.
  • At least one spring is provided which acts on the spring support, the spring snapping during rotation of the spring support and acting up to the snap point on the switching bushing against the direction of rotation of the shift lever and from its snap point in the direction of rotation of the shift lever.
  • a toggle lever under spring preload is used for the actual actuation of the switch, the selector shaft positively interacts with a play in the circumferential direction with a lever arm of the toggle lever and the toggle lever snaps during the rotation of the selector shaft to trigger the switching process of the switching contacts.
  • the gear lever can be pivoted through an angle of 180 °, whereby the spring cooperating with the spring bracket ensures that the gear lever, regardless of the switching behavior of the switching contacts, assumes the defined end position, so that the switching status of the device can be clearly recognized from the outside can.
  • the electrical load switch has proven itself in practice, especially when it comes to its operability and safety.
  • the object is achieved in a switching mechanism for an electrical load switch of the type mentioned in that the actuating means has an electric motor and a transmission, the output of the transmission interacting with the driver element in a movement-locking manner.
  • an electromotive direct drive of the driver element takes place, which triggers the actual switching process of the electrical load switch by means of the switching element.
  • the direct drive has the consequence that the movement of the electric motor and the driver element, and thus taking into account the freewheel also the movement of the switching element is reproducible, so that a defined movement of the electric motor leads to a defined movement of the switching element.
  • the actuating means thus has no clutch or the like, which would result in the movements of the electric motor and driver element not occurring in any defined context.
  • the switching mechanism according to the invention with the actuating means having the electric motor thus differs from the basic principle of known circuit breakers, which serve the purpose of achieving extremely short switch-on and switch-off times by using spring accumulators that can be preloaded by motor or by hand, in the event of a short circuit a latch of the spring accumulator is released to effect the switching process.
  • actuating means In order to implement the principle of the direct electromotive drive according to the invention using a gearbox, but nevertheless to ensure that manual switching is possible when the electric motor is not functioning, actuating means must be provided which have no self-locking.
  • a DC motor with planetary gear is preferably used as the drive. This enables a manual emergency mode for the switching process.
  • the gear reduction allows to use a DC motor with a relatively low current consumption and a high torque at the same time.
  • the direction is controlled by reversing the polarity. Different speeds enable two speeds.
  • the planetary gear can also interact with a bevel gear, the output gear of the bevel gear cooperating with the driver element in a non-positive manner.
  • a means for manually moving the driver can be brought into engagement with this or any other component that is connected to the driver in a movement-locking manner.
  • the means for manual movement can be designed, for example, as a socket wrench, which can be inserted into a plug-in opening of the output wheel of the transmission in a torque-transmitting manner.
  • the driver element is designed as a driver pin, which is arranged parallel to the axis of rotation of the output wheel and connected to it, the driver pin with the Interacts as a switching socket designed switching element that has a freewheel recess.
  • This design allows a compact arrangement of the components with an orientation of the output axis of the output wheel, which corresponds to the orientation of the output axis of the manually operated switching mechanism according to EP 0 496 212 A1.
  • the unit consisting of these components and the cover can be exchanged for the corresponding unit of EP 0 496 212 A1, which accommodates the cover and the elements used for manual operation will.
  • the electrical load switch can thus be operated by a motor in one case and manually in the other case - in which an electrical actuation is not desired.
  • the housing that the Cover takes up essentially has the switch contacts of the switch and means that transmit the movement of the switching element to the switch contacts, as they were mentioned in the discussion of EP 0 496 212 A1.
  • the switching element advantageously has a bore with a radial receiving slot for inserting a housing-side switching shaft with a radial pin.
  • various security mechanisms serve to display the position of the driver element or the position of the parts connected to it in a rotationally locking manner, furthermore enable detection of certain angular ranges of the driver element and include further switches provided for the purpose of security .
  • the rotary encoder used thus has the task of determining the position of the driver element.
  • the encoder must deliver an absolute value, since it must be possible to determine the position at any time without mechanical movement of the drive. For safety reasons, this encoder should be designed redundantly to rule out sensor errors.
  • the invention is not limited to the fact that the position of the driver element or of the components connected to it in a movement-locking manner is detected by means of an angle encoder. It is also conceivable to detect the position optically, for example by means of a roller that is connected to the driver element in a movement-locking manner and is provided with a bar code that is scanned by light barriers.
  • the advantage of such a representation lies in the fact that it works without contact and therefore without wear.
  • the detection of certain angular ranges of the driver element or components connected to it in a movement-locking manner takes place, for example, by means of a cam disk which is provided with one or more cams with which an electrical actuator, in particular a microswitch, interacts.
  • Two cams are expediently provided, one cam defining the setting range of the driver element and thus the end regions of this cam defining the switch-on and switch-off point of the electric motor, and the other cam defining the range in the event of failure of the electrical switching element facing the first-mentioned cam, by switching off the electrical load switch as a whole becomes.
  • a permanent self-monitoring of the electrical switching elements is preferably carried out, that is, even if the switching element is not to be rotated so far that it triggers the actual switching process.
  • Self-monitoring takes place, for example, every minute, and in the monitoring phase the software does not evaluate the overriding of the cams and thus actuation of the switching elements in the sense of a malfunction, but only that the electrical switching elements are functioning.
  • the software can also permanently monitor the function of the rotary encoder.
  • the monitoring of the angle of rotation encoder and the position of the driver element by means of the microswitch serves in particular the purpose of preventing destruction of the switching mechanism by driving through an unauthorized pivoting range of the driver element.
  • a further electrical switching element which detects the opening and / or closing position of the switch contacts of the switch. Errors in the system, such that, for example, the rotary angle encoder indicates a position of the driver element that corresponds to the open position of the switch contacts, but the switch contacts are closed, are thus excluded.
  • the electrical switching element which detects the position of the switching contacts of the switch, has top priority in the software monitoring the switching elements, so that in the event of a contradiction in the statement made by the electrical switching element, which is assigned to the switching contacts of the switch, to the other electrical switching elements, the load switch as a whole is switched off.
  • a power supply from the housing into the cover to the current-carrying parts mounted in the cover is to be provided.
  • a further electrical switching element should be provided, which detects the opening and / or closing position of the cover.
  • the load switch is de-energized in order to avoid endangering third parties. Only when the cover is closed is this electrical switching element switched in such a way that current reaches the components mounted in the cover and the motor can be operated.
  • the lid is monitored by the software.
  • a DC motor with a planetary gear in connection with a bevel gear is used in the switching mechanism for the electrical load switch, with the advantage that the switching process can be carried out manually by means of the electric motor or in the event of its failure.
  • the non-self-locking gear allows a clutch to be saved.
  • the rotary encoder enables exact position detection; if a corresponding marking is attached to the driver element or to a component connected to it in a movement-locking manner, exact position detection, in particular the end positions of the switch, is also possible in manual operation, that is to say if the potentiometer fails. From Of particular importance is the modularity or interchangeability of the manual drive with a motor drive.
  • the actuating means are integrated in the cover, while the components which actually cause the switching operations are placed inside the housing. As a result of the freewheel between the driver element and the switching element, the electric motor can run on. It does not have to end its movement abruptly as with a stepper motor.
  • the recorded quantities of the electric drive also include statistical values, such as the number of switching cycles and operating hours.
  • the electronic drive control should have its own monitoring, in which the most important components of the drive are tested for function. For safety reasons, this self-test is carried out during operation and is based on the redundancy of the sensor components used.

It consists of three switch modules 5 arranged in a housing 2, which can be actuated via the common switching mechanism 3. Each switch module 5 has an NH fuse link, not shown, with two contact blades that are inserted into Lyra contacts 8. Lines 9 and 10 are connected to the lyre contacts 8. Each line 9 or 10 has two separate, fixedly arranged contact tracks 11 and 12, and by means of the switching mechanism 3 contact bridges 13, 14 which can be moved or moved towards one another and which, in their switching position (FIGS. 1 and 2 illustrate their open position) , connect the two associated contact tracks 11 and 12. Two actuating slides 15 and 16, which are arranged parallel to one another and are movable in opposite longitudinal directions, are also provided.
  • the one actuating slide 15 has axially displaceable in it the two contact bridges 13, which are each biased by two springs 17 in the closed position.
  • the other actuating slide 16 accommodates the other two contact bridges 14 in an axially displaceable manner, each of these contact bridges is prestressed into their closed position by means of a spring 18, in which it comes to lie diametrically to the other associated contact bridge 13 on the contact tracks 11 and 12.
  • the switch modules 5 arranged on the right of the switching mechanism are mirror images of the switch module 5 arranged on the left of the switching mechanism 3.
