Definitions

  • the invention relates to a switching arrangement with a housing for accommodating and switching load switches, and with a switching strip actuation (preamble of claim 1).
  • the load switches can be of various types, for example designed as switch disconnectors or as diverter switches. These load switches can be provided with fuses. Different designs are known for this. Versions of such switches are required to be as versatile as possible, and a large number of installation advantages are also required. As far as the known load switches can meet these requirements at all, there is the disadvantage of a large number of device versions for the different applications. This, in turn, requires a considerable amount of extra work in production and especially in warehousing. Another major disadvantage of the prior art switch is that they have only one switching strip and thus only have two switching contacts. This limits the size of the currents to be switched, since otherwise an impermissibly large arcing would occur.
  • the object of the invention is to improve structurally and functionally an arrangement according to the preamble of claim 1.
  • it should be designed in such a way that it can be used for receiving and switching load switches of different designs and thereby avoids the considerable additional effort and the large inventory of the prior art explained above.
  • Fuse switch switch disconnectors with fuses
  • diverter switch diverter switch in the same housing and operate with the safety edges mentioned.
  • the arrangement of a common housing and two switching strips according to the invention can be built considerably more compact than the housing of previously known switches with only one switching strip. If necessary, some individual parts still need to be replaced and switch contacts positioned.
  • the invention enables another goal to be achieved, namely to be able to double the strength of the current to be switched with a load switch of approximately the same dimensions as in previously known switches provided with only one isolating strip.
  • the features of claim 2 are used for this purpose. Instead of two switching contacts so far, four switching contacts have been provided, with the synchronous actuation of the two switching strips ensuring simultaneous power interruptions. You also have twice the number of switching options. In this way, compared to correspondingly large, previously known switches with only two switch contacts and while maintaining the same size of the arc development, currents can be switched with approximately twice the strength. Preferably, a synchronous and opposite movement of the two switching strips is recommended for this.
  • An advantageous and preferred embodiment of the invention is the subject of claim 6. This achieves the advantage of attaching such an arrangement to a busbar system (see FIG. 5 of the drawing) also for attachment to the central busbar to have free access directly from above, for example to a fastening screw for a claw-like screw fastening.
  • the distance between the two switching strips provided according to claim 6 also makes it possible to accommodate a spring switching mechanism approximately in the middle of this distance (see claim 7 in this regard). You can also provide N contacts in the area between the two safety edges.
  • a 2 x 4-pole switch is thus created with a small footprint and the possibility of free space to the two safety edges.
  • the housing which is frame-like in plan view (see FIG. 1), consists of the lower housing part 1 and an upper housing part 2.
  • two switching strips 3 are longitudinally displaceable 3'-3 'next to each other and parallel to each other. This shift takes place synchronously and in opposite directions by means of a spring switching mechanism 4 which is common here and whose structure and function will be explained in more detail below.
  • the connection contacts 5 are located in the lower housing part 1.
  • the counter-connection contacts 6 are mounted in the upper housing part 2 and lead, for example, to the network or to the consumer. Depending on their sliding position, the switching strips 3 connect with their switching contacts 7, the connection contacts 5 with the counter-connection contacts 6 or they separate such a connection.
  • the switching strip 3 consists of an insulating material
  • the carrier 10 of the switching contacts 7, on the other hand consists of a conductive material, e.g. a metal like copper.
  • the same housing 1, 2 can be used to accommodate different load switches.
  • its width B and its length l can be a standard measure for the planning of electrical systems in which such switches are to be used.
  • the two switching strips 3 are at a distance from one another which enables the connection contacts 5, 6 to be detected by means of the switching contacts 7.
  • the spring switching mechanism 4 already mentioned above has two switching arms 11 on a drive disk 14, which end in driver pins 12 which are approximately circular in cross section. These move in recesses 13 of the ends of the switching strips 3 located at the bottom in FIG. 1. In this position of the switching strips 3, the right switching strip is shifted upwards and the left switching strip is shifted downwards ("off" position of the contacts). If the selector shaft 14 of the rear derailleur 4 is rotated clockwise, after driving through a certain angle of rotation (calculated freewheel) the driver pins 12 come to rest against the surfaces 13 'of the recesses 13, whereby the springs of the rear derailleur have already been partially tensioned.
  • the spring switching mechanism After passing through another small swivel angle of, for example, 10 °, the spring switching mechanism triggers and suddenly moves the two switching strips 3 in the arrow directions 14, 15 in opposite directions upwards and downwards into the switching position "on", in which the switching contacts 7 of the switching strips Establish contact (see Fig. 2). A current can then flow from the left connection contact 5 via the connection counter contacts 6 and the fuse 9 to the connection contact 5 shown on the right in FIG. 2.
  • the switching strips are forcibly moved somewhat in the direction of the arrows 14, 15 in order to forcibly separate contacts welded to one another.
  • switching strips 3 which are dark in their front edges in FIG. 1, congruent or congruent so that one and the same switching strip can be used with the same envelope for the left and for the right switching strip by by Corresponding rotation of this switching strip around its longitudinal axis achieves that the two switching strips lie side-by-side within the switching arrangement.
  • FIG. 3 The side view of FIG. 1 is shown in FIG. 3, the numbering from FIG. 1, 2 being adopted and the cutting line being guided through the longitudinal central axis according to the dash-dotted line III-III in FIG. 1.
  • the switching strip 3 according to FIG. 3 is, according to FIG. 1, the right half in the position in which it does not connect the contacts 6, 5 or 5 'to one another, i.e. Switch position "Off".
  • a shift of this switching strip shown in FIG. 3 by means of the switching mechanism 4 to the right then brings its two switching contacts 7 into contact with the connecting contacts 5, 5 'and 6.
  • the fuses 9 are inserted or pulled out from above into a fork-like plug holder 15 of the mating contacts 6.
  • Fig. 4 shows the side view of Fig. 3, but with the modification that Fig. 4 shows the variant of the invention to provide the spring mechanism 4 in the middle.
  • the respective square selector shaft 14 is rotatably supported at one end in the lower housing part 1 and at the other end in the upper housing part 2.
  • the above-mentioned distance between the two switching strips enables such a spring switching mechanism in this distance range between the two switching strips to accommodate.
  • the aforementioned free spaces 16 and also free spaces 17 provided below the switching strips in the lower housing part can also be configured in a different configuration or function than shown in the drawings. In this way, 16 switching contacts can be led directly down to conductor rails via the free space (see the exemplary embodiment of FIGS. 5-8 explained below). Magnets can also be accommodated in the free space. In the open spaces 17 one can have space for the collection and later discharge of ionized gases and the like and more.
  • FIGS. 5-8 shows how a load switch according to the invention can be placed directly on busbars L1, L2 and L3 and can thus be connected mechanically and electrically.
  • Each of these three busbars is electrically connected via an adaptation in the form of a claw-like screw fastening 19, 19 'for the busbar L1, L2 and L3 and associated contacts 24, 25 and 26 to the respective switching strip 3 (two switching strips are also provided here).
  • Four-contact circuits also take place here, with counter-connection contacts 6 likewise being led upward out of the switch in accordance with the previous exemplary embodiment.
  • contacting with the busbars L1, L2 and L3 could also be provided by means of conventional, separate adapter plates.
  • connection contacts 5 The top view of FIG. 5 shows that the rails L1, L2 and L3 form the current leads, while the current leads are formed by connection contacts 5, which are shown in FIG. 5 below.
  • the neutral conductor on the other hand, has a connection contact 5 (N) for the input as well as for the output.
  • FIG - 9d schematically show how the invention can provide the user with various switchgear designs with one and the same housing and, if necessary, still exchanging individual parts such as connection contacts and removing a safety edge.
  • This is the formation of different switches, but each provided with a housing and two switching strips, the switching strips interacting with the various connection and counter-connection contacts 5, 6.
  • These contacts can be exchanged and exchanged for other contacts, which is easily possible after loosening and lifting off the upper housing part 2 from the lower housing part 1.
  • the switching strips 3 can remain in the lower housing part.
  • Fig. 9 shows a four-contact version with contacts 5, 6 and the two switching strips 3, each switching strip being represented by two parallel lines. This corresponds to the embodiment according to Figs. 1-4, i.e. a switch disconnector with fuse.
  • Fig. 9a shows a switch disconnector, which essentially corresponds to the embodiment according to Fig. 9, only that the fuse 9 is missing here and instead a contact bridge 21 is provided between the two mating contacts 6, e.g. with on-off switches.
  • FIG. 9b A further embodiment is shown in FIG. 9b in which the connection contacts 5 leading to the consumer (only one of which is shown) are optionally connected to a network 22 or an emergency power supply 23 via the switching strips 3 can, for example with switches.
  • the switching strips 3 are actuated synchronously and in opposite directions to one another (see here the explanations for FIGS. 1-4), in the embodiment according to FIG. 9b the timing of the movement of the switching strips is different.
  • the right-hand safety edge 3 in FIG. 9b is first moved from the "on” position to the "off” position, and only then is the left-hand safety edge 3, which switches on the emergency power generator, from the "position". Switched from "to the position” On “. This does not run synchronously with the shifting of the right safety edge, but after that.
  • 9c shows an on-off switch which is provided with only one switching strip which is moved up and down in accordance with the arrows shown.
  • This embodiment serves to demonstrate that a housing designed according to the invention for accommodating two switching strips can also be used in this way, which increases the universality of the application.
  • FIG. 9d shows the switching principle of the embodiment of FIGS. 5-8, the numbering of FIGS. 5-8 in FIG. 9d being adopted for better understanding.
