Definitions

  • a pole for a circuit breaker the invention relates to a switch pole for a power ⁇ switch with a pole shell for receiving Rheinmit ⁇ stuffs for forming a current path and a vacuum switching ⁇ tube for switching a guided via the current path current with fastening means len for attaching whilisolierti-.
  • Such a switch pole is known from WO 2007/016881 AI ⁇ known.
  • the disclosed therein switch pole for a power ⁇ switch comprises a support frame as a pole shell, in which a vacuum interrupter and corresponding connection means are added to form a current path. Attachable to the support frame additional insulating parts are provided, wherein the U-shaped additional insulating parts snap with their legs inwardly arranged fastening means of the support frame a.
  • Object of the present invention is to develop a switch pole of the aforementioned type which has a structurally simple structure.
  • the fastening means are formed by a ver ⁇ bound to the housing and spaced therefrom arranged upper portion and connected to the housing and spaced therefrom arranged lower portion, which together form a guide slot.
  • Such a guide slot formed by an upper and a lower portion, which are connected to the pole shell and spaced therefrom, is a structurally simple outer attachment means, because such a fastener can be produced in a simple manner during the manufacturing process of Pol ⁇ shell of the switch pole For example, in the production of the pole shell in a casting process by appropriate design of the mold.
  • the fastening elements of Viennaieriiles are formed by two latching hooks, each with a hook portion.
  • Derarti ⁇ ge latching hooks as fasteners of Viennails are also structurally simple in a manufacturing process, for example during the casting process, be formed and made ⁇ union with appropriate design of the insulating part of a plastic, casting resin or the like by their elasticity in a simple manner the formation of a positive connection Engaging in the outer attachment means of the pole shell.
  • the beautisolierteil further holding elements for holding the quasisoliertils on the pole shell.
  • Such further retaining elements for example in the form of a guide element interacting with outer guide means or in the form of an upper or lower cover and side covers, likewise lead in a simple manner to a shark.
  • sion and stabilization of regisoliertils to the Pol ⁇ shell of the circuit breaker because by the researchersselemen ⁇ te and upper or lower or side covers each a guide or support of paragraphisoliertils is formed on the pole shell and at the same time by the overlap of vinisolierteil and pole shell are increased by upper, lower or side cover hit widths, and thus the dielectric properties of the Heidelbergerpols be improved.
  • Figure 1 is an embodiment of a switch pole for egg ⁇ NEN circuit breakers
  • FIG. 2 shows a detailed view of the switch pole of FIG. 1;
  • Figure 3 the switch pole of Figures 1 and 2 in an assembled state.
  • Figure 1 shows a switch pole 1 for a circuit breaker not shown in detail, which circuit breaker usually has three juxtaposed switch poles for switching or interrupting a guided over the circuit breaker current.
  • the GmbHerpol 1 comprises a pole shell 2 for receiving connection means in the form of Polkopf and Pollini and a arranged between Polkopf and Poltron vacuum interrupter (figuratively not shown), so that over Polkopf, vacuum interrupter and Poltridge a current path is formed and the vacuum ⁇ interrupter for switching or interrupting the stream is provided.
  • An insulating shell 3 as a repayisolierteil is provided for attachment to the pole shell 2, so that by pole shell 2 and insulating 3 insulation of the switch ⁇ pole 1 with respect to its adjacent switch poles of Leis and ground plates and similar elements which are at ground potential, is formed.
  • the insulating shell 3 has insulating sleeves 4 and 5 for the isolation of connecting lines for connecting the switch pole 1 with busbars of a switchgear, in which the circuit breaker is used on.
  • the insulating shell 3 further comprises an upper cover 6, a lower Abde ⁇ ckung 7 with a passage opening for a drive rod of the circuit breaker for initiating a drive movement in a moving contact of the vacuum interrupter, and a lateral edge 8, with which on the one hand in cooperation with the pole shell 2 a Attachment and stabilization of the insulating shell 3 to the pole shell 2 and on the other hand by the overlap of the covers 6 and 7 and the edge 8 with the pole shell 2 an increase in the strike distances and thus an improvement in the dielectric strength is formed.
  • Fixed To ⁇ supply elements 9 and 10 and a guide member 11 are shown connected at both ends to the insulation shell ⁇ tig 3, of which only the figurative arranged on the front side.
  • the fastening ⁇ elements 9 and 10 and the guide member 11 are used to Be ⁇ fixing the insulating shell 3 at the outer fastening means 12 and 13 or guide means 14 and 15 and will be explained in more detail with reference to FIG. 2
  • the pole shell 2 has WEI terhin through holes 16, only two of which are visible in the figure 1, with which the pole shell 2 can be secured to a figurative also not shown base plate of the Leis ⁇ tung switch.
  • Figure 2 shows a detailed view of the insulating shell 3 and the pole shell 2 in the region of the outer fastening means 12 and 13 of the pole shell 2, which verbun ⁇ dene and arranged from this spaced upper and lower portions are formed than with the pole shell and together form a guiding form slot 17 in which the fasteners 9 and 10 in the form of latching hooks of the insulating shell 3 can be inserted.
  • the locking hooks as fastening elements 9, 10 have since ⁇ at a hook portion 18 with a retractable slope 19, wherein upon insertion of the latching hooks into the guide slot 17 by the elasticity of the latching hooks they are elastically deformed upon contact of the retractable bevel 19 with the guide slot 17 and upon passage of the hook sections 18 through the guide slot 17 by the elastic rearward deformation the hook sections 18 on the upper and the lower Ab ⁇ section of the outer fastening means 12 and 13 abut, so that by this engagement fastening of insulating shell 3 is formed on pole shell 2, which is only by actively squeezing the latching hook against each other again releasable.
  • FIG. 3 shows the switch pole 1 in the assembled state in which the locking hooks are engaged as fastening elements 9 and 10 in the outer fastening means 12 and 13 and fixed and the guide element is also introduced 11 into the Actuallysmit ⁇ stuffs 14 and 15, wherein upper and un ⁇ tere cover 6 and 7 and the side edge 8, the Pol ⁇ shell 2 enclose, so that a complete isolation of the Wegerpols against adjacent switch poles as well as located at ground potential components of the circuit breaker is formed in a positive Be ⁇ consolidation of the insulating as vinisolierteil on the Pol ⁇ shell through the fasteners 9 and 10 to the outer fastening means 12 and 13th
