Definitions

  • the invention relates to a low-voltage circuit breaker with one consisting of a back wall and a front part Housing and located in this housing contact system, the at least one, expediently two approximately parallel, fixed by fasteners, retractable, from a profiled semi-finished produced connecting rails, for connecting the contact system to an external circuit having, wherein the connecting rails through in the Rear wall located openings extend through and Spacers are positioned in the housing and wherein Furthermore, one of the connecting rails as a carrier of a stationary Switching contact and an arcing horn is used during the other of the connecting rails by a hinged or flexible conductor arrangement with a movable switching contact the switch contact system is in communication.
  • Connection rails of circuit breakers are the switch side Connection points of the contact system to the rail systems the switchgear. They will either be at fixed installation ages directly or with slide-in switches via lamellar contacts with the busbars or field busbars of the switchgear connected. At the pushed out of the housing to the outside Part of each connection rail can therefore be another, plant side Rail are bolted or slide-in switches a disconnect contact be attached.
  • the upper connecting rail with the fixed switching contact must be in the insulating wall body be fixed, there during the switching process the moving contacts with full force on the solid Impact contact.
  • connection bars must continue to be designed so that they are rationally manufacturable and are capable of certain To fulfill functions. These features are: current carrying capacity, the heat dissipation, an entry contour for the lamellar contacts, a surface for front connections as well as the recording and transmission of static and dynamic forces. So it's a vigorous and dynamic high claimed place.
  • connection bars For the mentioned circuit breakers with high rated currents from, for example, 1000 A to 6000 A have the connection bars a considerable cross-section. That's why to provide them with several cross holes and it is one appropriate number of fasteners required.
  • connection bars of low-voltage circuit breakers which are sawed off from a profile material with one or more projections, such that the connecting rails are inserted through a hole and serve or the projections of the profile material as stops of the connecting rail on the switch housing and thus form the force transfer of the switching forces on the housing.
  • connection rail is from the inside through the passage opening of the housing wall inserted and supported by means of a projection on the rear wall of the housing from.
  • connection rails are also made of profiles Sawing (longitudinal or transverse) made.
  • the housing has uniform Cutouts for the connecting rails on, respectively designed for the largest rated current.
  • Connecting rails of smaller rated currents become spacers Made of plastic, which uses the interstices to fill.
  • the mounting of the spacers has the disadvantage of additional Cost of these parts and higher installation costs and they form a source of error for a customer Assembly of the current paths.
  • the object of the present invention is therefore to to provide a connecting rail which is designed so that Connection rails of different currents without additional Spacers in switch housings with uniform Through openings can be used.
  • Connecting rails are designed so that the spacers as a one-piece part are integrated into the connecting rail.
  • the openings in the switch rear wall are how already mentioned, the maximum rated current of the respective Type series of low-voltage circuit breaker accordingly educated.
  • the connecting rails are provided with stops for axial positioning in the housing and to secure against axial displacement Mistake.
  • connection bars on provided for the attacks. That may be appropriate lag screws be. But there are also other means for axial admission the connecting rail in the direction of the stop and thus possible for axial fixation.
  • the single FIGURE shows a sectional view through the area a low-voltage circuit breaker in which the connecting rails are guided through the switch rear wall.
  • the upper passage opening 10 and the lower passage opening 11 for the connecting rails 2 and 3 through the rear wall 4 of the low-voltage circuit breaker 1 are dimensioned that a connecting rail 2, 3 with the highest possible for the rated current of the low-voltage circuit breaker 1 required cross section can be passed.
  • the low-voltage circuit breaker 1 only for one lower operating current is designed for the connection bars 2 and 3 only a smaller cross section needed. Then spacers 12; 13; 14; 15 required to the difference between the cross section of the passage openings 10, 11 and the thinner connecting rails 2, 3 compensate. These spacers are according to the present Invention integrally integrated in the connecting rails and support these securely against the back wall 4 of the housing Low-voltage circuit breaker off.
  • the upper connecting rail 2 is against displacement in the direction of its axis secured by an extension 16 of the against a stop 17th the housing of the low-voltage circuit breaker 1 is applied, around the charge applied by the switch contacts To get in contact. To avoid loosening is the upper connecting rail 2 by means of a tension screw 18th acted upon the connecting rail 2 locked against stop 17.
  • the lower connecting rail 3 is also against displacement secured in the direction of its axis by an extension 19 against a stop 20 of the housing of the low-voltage circuit breaker 1 is present.
