Definitions

  • the invention relates to a low-voltage circuit breaker having a first contact arrangement for connecting a stationary contact with a first busbar and with a second contact arrangement for connecting a counter-contact arranged on a contact lever to a second busbar.
  • Low-voltage circuit breakers of the type mentioned have contact arrangements in order to enable rapid connection or disconnection of the switch with current-carrying rails. This is desirable, inter alia, for removal or maintenance of the low-voltage circuit breakers. Low-voltage circuit breakers are designed for different nominal currents in different sizes. The aim is to keep the structural dimensions of a low-voltage circuit breaker as low as possible.
  • Low-voltage circuit breaker of the type mentioned can be performed on the one hand as a fixed switch, on the other hand as a slide-switch.
  • the circuit breaker With slide-in switches, the circuit breaker is moved and locked in a slot provided for this purpose. This allows a faster and easier connection or disconnection of the circuit breaker from the busbars as the fixed-mounted switch. Therefore, it is desirable to be able to convert fixed-installation switch with the least possible material and labor in slide-switch.
  • US 3,343,042 discloses a low-voltage circuit breaker having a first contact arrangement for connecting a fixed contact with a first bus bar and with a second contact arrangement for connecting a contact contact arranged with a counter-contact with a second Busbar, wherein the busbars have at least one contact area over which the busbars for forming the low-voltage circuit breaker as a slide-in switch can be permanently arranged on a slide-in frame of the low-voltage circuit breaker.
  • a particular advantage of the present invention is that the already existing busbars of a fixed switch for retrofitting into a slide-in switch in the simplest way can be used again.
  • the receiving area for retaining means is designed such that the busbars are permanently, but reversibly, on the outside of the low-voltage circuit breaker can be arranged.
  • the contact region is designed such that the busbars can be arranged permanently, but reversibly, on the insertion frame of the low-voltage circuit breaker.
  • busbars By the aforementioned design of the busbars, it is possible to use these in a fixed installation switch to arrange directly on the fixed switch, but it is also possible to permanently arrange these busbars at a conversion of the fixed switch in a slide-in switch after removal from the fixed switch to the slide-in frame of a slide-switch, so that the conversion of a fixed installation Switch in a slide-in switch with minimal material costs associated with, since this conversion only an additional drawer frame is necessary. Due to the intended contact area, the busbars can be arranged directly on the slide-in frame. In this case, the surfaces of the contact area with the surface to be contacted of the insertion frame plan to complete. The fact that the busbars have a receiving area for holding means, they are permanently acted upon by a holding means and can thereby be locked permanently on the insertion frame of a circuit breaker.
  • both the first and the second busbar identical dimensions.
  • the same contact arrangements which are preferably designed as isolating contact arrangements, can be used both for the first busbar and for the second busbar.
  • the busbars in the formation of the low-voltage circuit breaker as a slide-in switch can be arranged on the slide-in frame that they have the same depth as the busbars in the formation of the low-voltage circuit breaker as a fixed switch. This ensures that the busbars must be permanently arranged only on holding means at their designated areas on the slide-in switch to realize a conversion from the fixed switch into a slide-in switch. The fact that arranged on a drawer busbars the same depth as the Busbars have the fixed switch, no further adjustment or conversion work is necessary.
  • bus bars are plate-shaped or wing-shaped.
  • a low-voltage circuit breaker 10 has a first contact arrangement 24, which establishes a connection between a first stationary contact 18 arranged on a connecting rail 17 and a first busbar 22. Furthermore, the circuit breaker 10 has a second contact arrangement 34 for connecting a second busbar 30 with a contact contact 16 arranged on a contact lever 14.
  • the low voltage circuit breaker 10 is in FIG. 1 executed as a fixed-installation switch by the two bus bars 22 and 30, for connection to not shown on the system side Busbars serve, are attached to the outside of the rear wall of the circuit breaker 10. For this attachment are first holding means 12, the first receiving areas 20 of the busbars pass through. The connection with the system-side busbars via not shown second holding means, the second receiving areas 13 of the bus bars 22 and 30 pass through.
  • the connecting rail 17 and the busbars 22 and 30 are formed identically, wherein the receiving portion 13 of the connecting rail 17 for receiving a fourth holding means 15 is used.
  • the fourth holding means 15 serves for fixing an arcing horn 19 to the connecting rail 17.
  • the first busbar 22 and the second busbar 30, which according to the invention have the receiving area 20 for holding means and a contact area 38 for the arrangement of the busbars 22, 30 on a slide-in frame 11 of the circuit breaker 10, contact the circuit breaker 10 with its side facing the circuit breaker 10 side.
  • the receiving area 20 is designed as a through hole.
  • the contact region 38 is located on the side facing away from the power switch 10 of the busbars 22, 30th
  • the bus bars 22, 30 according to the invention of a permanent installation switch as in Fig. 1 and Fig. 2 shown removed from the fixed switch and to be arranged on a slide-in frame 11 of a circuit breaker 10, as in Fig. 3 is shown. Furthermore, the bus bars 22, 30 arranged on the insertion frame 11 can be permanently locked by third holding means 35.
  • the holding means realize over the receiving areas 20 for holding means a permanent, non-positive connection between the bus bars 22, 30 and the insertion frame 11, as in Fig. 4 is shown.
  • the circuit breaker according to the invention can be realized particularly advantageous.
  • the drawer frame busbars 22, 30 configured as a withdrawable circuit breaker circuit breaker have the same installation depth as the busbars configured as a fixed-mounted circuit breaker in its operating position.
  • the bus bars 22 and 30 are arranged on the plug-in circuit breaker associated inside of the insertion frame such that they are inserted with slide-in circuit breaker, as well as in the case of the fixed circuit breaker configured for FIGS. 1 and 2 Contact the circuit-breaker with its side facing the circuit-breaker.
