Definitions

  • the invention relates to low-voltage switches with a locking lever, which can be designed as a disconnector or a circuit breaker and in which the locking lever prevents the transfer of the operating handle to the off position when the contacts of the switch are blocked, according to the preamble of claim 1.
  • a low voltage circuit breaker which is equipped with a locking lever for breaking open blocked contacts.
  • This locking lever is rotatably mounted on the selector shaft.
  • the locking lever engages like a fork over a working surface on the drive lever of the actuating device and the joint of the knee joint lever, the fork having a suitable play with the abovementioned attachment points. If an attempt is made to turn off the circuit breaker when the movable contact block is blocked, the locking lever with its fork arm is first carried along over the working surface of the drive lever until the other fork arm is removed against the knee joint pin. With a certain amount of force on the actuating handle, the toggle levers can then be bent in the switch-off direction.
  • DE 30 33 212 C2 shows an electrical switching device that acts as an emergency stop switch.
  • the switching device receives the mode of operation as an emergency stop switch in that the drive lever and the toggle lever articulated on the abutment have cooperating work surfaces in the switch-off direction, which exert a force component acting in the sense of separation on a switching element that remains incorrectly in the switched-on position.
  • An action of a locking lever for coupling the drive lever and contact arm is not present in this switching device.
  • the GM 80 23 509 shows a low-voltage circuit breaker with a locking lever to prevent the operating handle from being moved to the off position when the movable contact block is blocked in the on position.
  • the locking lever is mounted in a bearing formed in the housing base and is connected to the actuating handle with its end opposite the bearing.
  • a working surface is formed by a bulge which, when switched on, is at a short distance from the knee joint pin of the knee lever.
  • the locking lever has an extension with a settlement that as Working surface cooperates with a counter surface of the movable contact.
  • the moving contact piece remains in the switch-on position when it is switched off by the actuating handle, the development of the locking lever comes to rest against the contact piece carrier and blocks the further pivoting of the drive lever.
  • a force effect can be exerted on the carrier by lever action around the bearing on the housing base, which force force is sufficient in some cases to separate the contact points welded together.
  • the effect of the locking lever is determined in this device by the position of the selector shaft in the switch housing.
  • the invention has for its object to provide a simple, space-saving and at the same time directly acting locking mechanism in a compact switch lock regardless of the position and embodiment of the control shaft.
  • the invention has the advantage that the arrangement of the locking plate behind the upper knee joint plate requires no additional space in the switch housing and operational movements within the key switch are not hindered.
  • the function of the locking tab can be optimized in an advantageous manner by designing the guide link in the drive lever.
  • the movable contact 1 of the low-voltage circuit breaker is rotatably mounted on an axis 2 in a control shaft 3.
  • the selector shaft 3 itself is fixed in the switch housing, not shown.
  • the axis 2 is also the point of attack of a lower knee joint bracket 5.
  • An associated upper knee joint bracket 6 is supported on a bolt 7 which is located on a latch lever 8.
  • the pawl lever 8 serves to trigger the overcurrent of the switching lock and is rotatably mounted on an axis 9, which in turn is mounted in a fixed position in a lock holder 10.
  • the lock holder 10 serves as a supporting frame for the switch lock of the switch and is fastened in the switch housing, for example by riveting.
  • the knee joint bracket 5 and 6 is arranged on both sides of the ratchet lever 8 and is connected in the middle to a knee joint pin 16.
  • two locking plates 11 are rotatably mounted on the axis 9. These locking tabs are coupled via drive pins 12 to the drive lever 13, the drive pins 12 being guided in the link arms of the drive lever 13.
  • the drive lever 13 is rotatably mounted on stationary bearing bolts 14 and is fixedly connected to an actuating handle 15 which is led out of the switch housing.
  • Lock holder 10 and drive lever 13 are also arranged on both sides of the pawl lever 8. With 22 a trigger shaft is shown with which the triggering of the pawl lever 8 is controlled in a known manner.
  • Fig. 1 shows that in the operating position ON, the locking tabs 11 serve as a stop for the knee joints by the upper knee link tabs 6 come to rest on the locking tabs 11 in the contact points 20.
  • the driving bolts 12 are in this operating position on an extension 25 of the lock holder 10 and thus form a stop for the drive lever 13.
  • In the operating position ON there is an opening 23 between movable contact 1 and switching shaft 3, such that the short end of the contact 1 play has against a stop surface of the control shaft 3.
  • the arrow 21 shows the direction of movement of the operating handle 15 when switching off.
  • the locking tabs 11 come into contact with the upper knee joint tabs 6 in the contact points 24. This contact occurs shortly before the force component of the drive springs 18 moves over the center of the bolt 7.
  • the locking tabs 11 exert a torque in the opening direction of the knee joints on the upper knee joint tabs 6. If the force component of the springs migrates beyond the bolt 7 when the knee joints are opened, the knee joints collapse and the contacts are switched off.
  • Fig. 3 shows the process of switching off or tripping via the trigger shaft 22 when the contacts of the switch are welded.
  • the knee joints and also the control shaft 3 move in the switch-off direction 21 to Through stroke 23 between contact 1 and selector shaft 3 is canceled.
  • the drive lever 13 with the coupled locking tabs 11 can only be tracked so far in the case of welded contacts that the locking tabs 11 come to rest on the upper knee-link tabs 6, which are located in a blocked intermediate position after lifting the through stroke 23. If one were to try to move the operating handle 15 further in the switch-off direction 21, the locking tabs 11 on the upper knee-link plates 6 would generate a moment in the switch-off direction.
  • the actuating handle 15 would, however, only be able to be moved if the contact welding breaks open.
  • the function of the locking tabs 11 with regard to the blocking position of the drive lever 13 and the breaking force acting on the welded contacts can be optimized by designing the guide links for the bolts 12.
  • arrow 19 shows the direction of movement of the operating handle 15 when switched on. In the illustrated OFF position of the switch, there is no contact between the locking tabs 11 and the upper knee joint tabs 6.
