Definitions

  • the invention relates to an electrical switchgear for mounting on automatic circuit breakers, in particular circuit breakers, with contact points for at least two potential-free switch poles, which are acted upon by an actuating device which cooperates with one or more coupling members which cover the flat sides of the housing of the switchgear and which have a narrow construction if necessary, reach through an adjacent circuit breaker, where they can transmit its switch position to the switch poles via the actuating device.
  • Auxiliary switches are provided for this purpose, which are arranged in addition to the self-switches installed in meter stations to protect the main circuits. It is advisable to attach the auxiliary switch to a permanently installed self-switch and to couple it mechanically to its release, so that in the event of a trip both the self-switch and the auxiliary switch attached to it are operated simultaneously.
  • auxiliary switch attachment for circuit breakers has become known from German utility model DE-GM 74 26 189, which has auxiliary contacts in a space separated from the circuit breaker, which are acted upon by an actuating device which engages with the adjacent circuit breaker.
  • the auxiliary switch attachment has a plurality of contact points arranged one above the other, which are formed by fixed contact pieces lying next to one another, each of which can be connected by means of a contact bridge.
  • the contact bridges are fastened to a contact bridge carrier designed as a slide, which can be displaced by an actuating element of the adjacent circuit breaker via a swivel lever.
  • a contact bridge carrier designed as a slide, which can be displaced by an actuating element of the adjacent circuit breaker via a swivel lever.
  • the actuating device is formed from two mutually independent switching mechanisms, each having a coupling member, which may be in engagement with the adjacent self-switch, that each switching mechanism acts on at least one switch pole, that each switch pole is designed as a changeover switch and that the actuating device has a first control handle and a second control handle.
  • a first switch pole as a signal switch for indicating the switch-on position or the result of a malfunction, ie. H. Short-circuit or overcurrent, caused switch-off position of the self-switch is used, while the at least second switch pole is used to switch other auxiliary circuits on and off.
  • An advantageous embodiment of the invention provides for the switching mechanism of the first switch pole, which is used as a signal pole, to be equipped with a test device Check that the rear derailleur is working properly.
  • this test device can also be used to control a signal circuit connected with this switch pole. It is also contemplated that if the adjacent circuit breaker is triggered, the signal provided in this case will not appear due to an error in the signal circuit.
  • the test facility is also provided in order to be able to locate such sources of error without interrupting the main circuit.
  • This test device is formed from a spring-loaded, longitudinally displaceable test button with a key surface on the end face and a sliding surface formed obliquely on its opposite end face, which cooperates with a release lever of the switching mechanism for the signal switch.
  • test device When the test device is actuated, ie when the test button is depressed, its sliding surface acts on a slide plate with a release lug, which in turn moves the release lever of the rear derailleur from its rest position and thus leads to the release of the rear derailleur, whereupon the associated switch pole comes into the off position. Simultaneously with the movement of the slide plate, an attached or integrally formed driver pin acts on a driver provided on the associated control handle, provided with a detent and moves it so that the control handle comes to the "off" position.
  • the switching mechanisms for the switch poles are acted upon independently of one another by the adjacent self-switch.
  • the signal switch which is used in particular to indicate error states in the main circuit of the circuit breaker - short circuit or overcurrent - is connected to a triggering element of the circuit breaker via the coupling element assigned to its switching mechanism.
  • This release element in turn works with both the magnetic and the thermal release of the circuit breaker and thus transmits its movement directly to the coupling member, which actuates the switching mechanism of the signal switch.
  • the switching mechanism of the at least second switch pole which is preferably used as an auxiliary switch for switching on and off other auxiliary circuits, is in engagement with the movable contact piece of the circuit breaker via the coupling member assigned to it.
  • the movable contact piece is mechanically coupled to the manual operating element of the automatic switch and can therefore be operated manually by the latter. Accordingly, with each manual actuation of the manual control element of the automatic switch, which is transferred to the movable contact piece, the at least second switch pole of the attached electrical switch, which is provided as an auxiliary switch, is simultaneously actuated.
  • the electrical switch also has a switching actuating element which is led out on the front side of the housing and is connected in a form-fitting manner to the self-switching manual actuating element for manually switching on the attached auxiliary and signal switch.
  • the switching mechanism of the first switch pole which serves as a signal switch, is advantageously designed in such a way that the signal pole can be switched on, but cannot be brought into the switched-off position by manual actuation of the manual control element of the self-switch.
  • the electrical switch is provided with a manual actuating element which serves as a visual switch position indicator.
  • the actuating member is formed from two control handles which are arranged pivotably about a common axis of rotation.
  • the first control handle which has a different color than the second control handle to distinguish it, is connected to the switching mechanism of the signal pole.
  • the second of the two control handles is for prepared form-fitting intervention in the manual control element of the adjacent self-switch and serves to switch on the switching devices at the same time.
  • it has a driver that serves to bring the signal pole switch mechanism into the ON position.
  • the switching mechanism of the signal switch can be switched on manually together with the adjacent self-switch or alone; however, manual deactivation of the signal pole is not possible. This is also not possible with the control handle that is directly engaged with the switching mechanism of the signal pole, since the latch provided in the switching mechanism can only be triggered by actuating the test button or by activating the thermal or magnetic release of the circuit breaker. Both lead to a change in position of the coupling member and thus to a triggering of the switching mechanism of the signal switch.
  • the electrical add-on switch is accommodated in a double-shell housing which consists of half-shells formed in mirror image.
  • the division level of the switch housing the thickness of which corresponds to half the module width of the usual self-switches, runs at half the thickness parallel to the flat side of the switch housing and divides it into two halves of equal thickness, which accommodate the individual parts of the switch including the connecting terminals.
  • connecting terminals which are usually provided with clamping screws and are inserted into pre-formed recesses in the housing shells, torsion-proof even against high torques when clamping the electrical connection conductors without further measures, e.g. B. Glue to install.
  • the pin assignment for the contact points is provided in a known manner on the upper and lower end faces facing the switch poles, with each connecting terminal recessed with its clamping screws being accessible only with tools.
  • the electrical switch can be attached to a circuit breaker at any time, i. H. also possible retrospectively by the customer, provided that the provided automatic switches are prepared for this.
  • the switching device is fastened to the self-switch by means of clamps which each encompass the narrow sides of the two housings and engage in a form-fitting manner in recesses on the flat sides.

  • the holding openings 34 which serve to hold holding elements (not shown in more detail), which are non-positively and / or positively connected to the automatic switch 11.
  • FIG. 3 shows the longitudinal section through the switching device 12.
