Definitions

  • the invention relates to an electromagnetic switching device with a switching position indicator that is operatively connected to the contact bridge support and that surpasses the contour of the switching device at least in one switching position.
  • either the switch position indicator is connected in one piece to the contact bridge support (DE-GM 73 27 169) or the switch position indicator, which is loaded by spring force against the display direction, is taken along by the contact bridge support after it has traveled a certain distance (DE-GM 72 30 068, DE-GM 71 16 559).
  • a direct display of the position of the contact bridge carrier is guaranteed by the switching position indicator, but since the switching paths of the contact bridge carrier are often relatively small, the position of the switching position indicator does not always provide clear information about the switching state of the switching device. This state is exacerbated in the switching devices mentioned below, since part of the displacement path of the contact bridge support takes place without movement of the switch position indicator. In this switchgear version, there is still no direct coupling between the switch position indicator and the contact bridge support, so that a jammed switch position indicator would signal the switch-off status of the device, although this is already switched on again.
  • the invention is thus intended to provide a switching device of the type mentioned above which, when using the electromagnetic drive, also has the isolating function, i.e. the main switch function can take over without having to expend a considerable amount of effort.
  • This is achieved in a simple manner in that the switch position indicator is coupled to the contact bridge support via a device such that the adjustment path of the switch position indicator is increased compared to that of the contact bridge support.
  • a simple design of the device according to the invention results if the device is a lever.
  • This embodiment does have the disadvantage that a relatively large space is required transversely to the direction of movement of the contact bridge carrier.
  • it has the advantage that the contact bridge support, which is normally automatically returned via the back pressure spring, can inevitably be brought into position by hand in the faulty state.
  • a space-saving solution with practically any size of the display path of the switch position indicator can be achieved if the switch position indicator is coupled to the contact bridge support with such play both in the on and in the switch-off direction that when opening the make contacts, the coupling between the switch position indicator and the contact bridge support opens one side of the game only takes place when the contact opening path meets the isolating function conditions and that the device consists of a snap mechanism which, when the contact bridge carrier moves further, brings the switching position indicator to the coupling with the contact bridge carrier on the other side of the game.
  • a structurally simple structure for the connection with play is obtained if the switch position indicator with a T-shaped projection in a rectangular recess of the contact bridge carrier which determines the play is slidably guided. It has turned out to be advantageous if the snap mechanism consists of a dead D nct spring.
  • the electromagnetic switching device shown in the drawing consists of the contact piece carrier, in the present case contact bridge carrier 1, which is released by the back pressure spring 2 when the magnetic drive (not shown in more detail) is de-energized Switching device is pressed.
  • the contact pressure spring 3 presses the contact bridge 5, which is displaceably guided in the window 4 of the contact bridge carrier 1, onto the fixed contact parts 6. Further contact bridges can be held in the contact bridge carrier 1, as indicated by dashed lines, which can interact with other fixed contact parts.
  • the switch position indicator 7 is guided with a T-shaped projection 8 in a rectangular recess 9.
  • the rectangular recess 9 has a passage 10 for the style 11 of the switch position indicator 7.
  • the walls 12 and 13 determine the play that the switch position indicator 7 has with respect to the contact bridge carrier 1.
  • An over-center spring 14 which is supported on the housing ensures the increased movement path of the switch position indicator 7 with respect to the contact bridge carrier 1.
  • the movement limitation is determined by a molding 15 which cooperate with the stops 16 and 17 of the cover 18.
  • a breakthrough 19 is used to hang a padlock in order to be able to lock the switching device in the exhibition.
  • the switch position indicator 7 is only taken along when the contact bridge support 1 has covered the path 20. In this case, the creepage distances and clearances between the fixed contact parts 6 and the contact bridge 5 are so large that the isolating function is fulfilled.
  • the dead center spring 14 is brought over the dead center position and the display jumps beyond the upper edge of the cover 18 until either the projection 15 abuts the stop 16 (that is the normal case) or in the event that the separation did not take place completely, the T-shaped attachment 8 can be placed against the wall 13, so that there is no defined display of the off state to the outside he follows.
  • the switch position indicator By placing the T-shaped extension 8 on the wall 13, the switch position indicator is pulled into the position shown in FIG. 1 when the switching device is switched on. In the display position of the switch position indicator, the switching on of the contactor can be blocked by hanging a lock in the passage 10, ie it is ensured that the switchgear cannot be switched on mechanically or electrically, for example, through maintenance work on the machine.
  • auxiliary control contacts 21 are additionally provided, which can be actuated by the molding 15 of the switch position indicator 7. This enables the disconnector function to be monitored.
  • security-relevant circles e.g. Upstream circuit breakers or the like take over the isolating function if the contactor fails. The control then takes place via the auxiliary control contacts 21 with an additional time delay.
  • the auxiliary switches usual for motor contactors are not suitable for such a monitoring function.
  • the position with 0 and I is identified by the pivotably mounted segment display 22, which is pivoted by the switch position display 7.
  • the arrangement shown in FIG. 4 can be provided so that the main switch function is performed, which requires manual operation and identification of the position.
  • a manual actuation of the switching device is achieved via a lever 23, which is pivotably mounted about the axis 24, via the plunger 25.
  • the plunger 25 is actuated, the break contact 26, which is in series with the contactor coil 27 in a voltage source, is opened first. In the normal case, the contactor switches off automatically when the contactor coil 27 is de-energized via the back pressure spring 2.
  • the contact bridge support 1 In the faulty state, e.g. mechanical sticking, the contact bridge support 1 is inevitably brought into the exhibition via the positively coupled lever 24.
  • the plunger 25 comes to rest with the surface 28 on the lever extension 29.
  • the gear ratios can be selected here so that on the one hand the tappet movement 25 which can be used as an indicator is large enough and on the other hand the lever ratios are sufficient to move the contact bridge carrier to such an extent that the isolating function results in the electrical sense by separating the contact bridge 5 from the fixed contact parts 6.
  • the passage 10 on the switch position indicator 7 can also be provided on the plunger 25. Locking projections 30 on the plunger 25 or lever 24 are used here to transmit the locking.
  • the switching device design according to the invention on the one hand ensures the galvanic isolation in safety circuits with little effort. Furthermore, the switching device design according to the invention is also becoming increasingly important due to the increasing use of electronic circuits, since electronic switching elements cannot in principle fulfill the electrical isolation.
  • the embodiment according to FIG. 4 enables the additional components to be combined in an additional module, so that the additional functions mentioned, manual operation, unambiguous switching position display, locking option in the open position, can also be achieved subsequently by the device. For this purpose, only a possibility of intervention on the contact bridge support is to be provided from the outside.
