Definitions

  • the invention relates to a low-voltage circuit breaker with one consisting of a rear wall and a front part Housing and a contact system located in this housing, the at least one, suitably two approximately parallel, insertable, fixed by fastening means connecting rails made from a profiled semi-finished product, for connecting the contact system to an external circuit has, with the connecting rails through in Window openings and extend through the rear wall Fasteners are locked in the housing and where also one of the connecting rails as a carrier of a stationary Switch contact and an arcing horn serves during the further of the connecting rails by an articulated or flexible conductor arrangement with a movable switch contact of the switch contact system is connected.
  • Connection rails of circuit breakers are on the switch side Connection points of the contact system to the rail systems the switchgear. They are either at fixed installation switches directly or with slide-in switches via slat contacts with the switchgear busbars connected. On the one pushed out of the housing Part of each connecting rail can therefore be a further, system-side Rail can be screwed on or with slide-in switches a break contact can be attached.
  • the upper connecting bar with the fixed switch contact must be in the insulating wall body must be fixed, since during the switching process the moving contacts with full force on the fixed Encounter contact.
  • the connecting rails must continue to be designed so that they can be produced rationally and are suitable for certain To perform functions. These functions are: the current carrying capacity, heat dissipation, an entry contour for the slat contacts, an area for front connections as well as the receptacle and transmission of static and dynamic forces. So it is a powerful and dynamic high claimed position.
  • connection rails have, for example, 1000 A to 6000 A a considerable cross-section. That is why to provide them with multiple cross holes and it's one appropriate number of fasteners required.
  • connecting rails of low-voltage circuit breakers which are sawn off from a profile material with one or more projections, such that the connecting rails are inserted through a hole and the or the projections of the profile material serve as stops of the connecting rail on the switch housing and thus form the force transfer of the switching forces to the housing.
  • this connecting rail used, which have an integrally molded bar, from which pieces are then cut off, which the Form the connecting rail.
  • the attachment of the connecting rail takes place from the side facing the switching contact system. This has the disadvantage that the attachment when assembled Switch is inaccessible, and the arrangement despite the Improvements such as cross holes no longer required in the connecting rails and reduced material and manufacturing costs, is not a satisfactory solution.
  • the object of the present invention is therefore to to create a connecting rail which is designed such that Connection rails of different currents without additional Spacers in switch housings with uniform Through openings can be used.
  • Connection rails are designed so that the spacers as a one-piece part are integrated into the connecting rail.
  • the "useful cross-section", ie the cross-section the current-carrying part of the connecting rail, the required Rated current is chosen thin and this by means of the one-piece with the connecting rail Spacers in which the maximum nominal current of the each switch type according to the passage opening in the rear wall of the low-voltage circuit breaker is supported. Since the connecting rails from one profiled material made by simple sawing For this purpose, it receives at least two molded parts Bridges whose dimensions are the difference between the Thickness of the connecting rail used and the size of the Passage opening in the rear wall of the low-voltage circuit breaker correspond.
  • the connecting rails are with stops for axial positioning in the housing and to prevent axial displacement Mistake.
  • the only figure shows a sectional view through the area a low-voltage circuit breaker in which the connecting rails are led through the rear of the switch.
  • On the upper connecting bar 2 are the counter contact 5 for the not shown movable switch contact and an arcing horn 6 with a pre-contact 7 for the movable Switching contact serving part of the arcing horn 6 arranged.
  • On the lower rail 3 are on the inside of the low-voltage circuit breaker 1 end 8 Flexible conductor cables, not shown, as current-carrying Connection to the movable switch contact attached.
  • a current transformer 9 is provided to the around the lower connecting bar 3.
  • 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 nominal current of the low-voltage circuit breaker 1 required cross section can be passed.
  • the low-voltage circuit breaker 1 is only for one lower operating current is designed for the connecting rails 2 and 3 only require a smaller cross section.
  • 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.
  • These spacers are in accordance with the present Invention integrated in one piece in the connecting rails and support them securely against the rear wall 4 of the housing of the Low voltage circuit breaker.
  • the upper connecting bar 2 is against displacement in the direction of its axis secured by an extension 16 against a stop 17 of the housing of the low-voltage circuit breaker 1, around the impact and exerted by the switch contacts Record contact force.
  • the upper connecting bar 2 by means of a lag screw 18 acts on the connecting rail 2 locked against the stop 17.
  • the lower connecting bar 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.
