Definitions

  • the invention relates to a switch with an arc extinguishing arrangement, with fixed contact parts, the ends of which are designed as guide rails for the arc, as are known for extinguishing the arc in connection with an extinguishing plate arrangement.
  • the quenching plate arrangement here consists of several quenching plates with an end quenching plate, the end part of which protrudes into the area of the running rail and an arc guiding plate made of electrically conductive material.
  • Such quenching plate arrangements are suitable for quenching arcs at high powers.
  • there are different requirements for the extinguishing arrangements For switches, especially contactors, it is customary to use arc chambers with extinguishing baskets for small outputs.
  • switches or contactor designs with corresponding extinguishing arrangements that are used depending on the power and other connection conditions. The effort required to stock up on switches and contactors is correspondingly high.
  • the invention is therefore based on the object of providing a switch, in particular a contactor, of the type mentioned above with an extinguishing arrangement which can be easily adapted to the respective power.
  • a switch in particular a contactor
  • This is achieved in that a U-shaped basket with its two legs is placed around each fixed contact part to extinguish the arc, and in that the connecting part between the legs has a cutout through which the running rail of the respective fixed contact part projects.
  • the advantage of the invention is that for the most frequently occurring operating voltage of 400 V, the corresponding arc chamber can be manufactured very inexpensively. At higher voltages e.g. 690 V and 1000 V can be used by simply changing the arc chamber, the same switch or the same contactor. This construction also eliminates the need for double storage for the various basic designs for switches and contactors, as well as separate storage for contact pieces.
  • switches or contactors are equipped with contact and quenching plate arrangements according to FIG. 2.
  • the contact arrangement here consists of two U-shaped fixed contact parts 1, which are mounted on connecting rails and the ends of which are designed as guide rails 2 for the arc.
  • the fixed contact parts 1 face the movable contact piece, ie the contact bridge 7 with its contact pads 9.
  • the quenching plate arrangement At a predetermined distance from the running rail 2 is the quenching plate arrangement with the quenching plates 8, via which the arc is conducted for quenching.
  • the same basic construction with the same contact arrangement can, however, also be used for lower powers and voltages of, for example, 400 V, although an extinguishing arc chamber with extinguishing baskets 3 is used according to the invention due to the lower requirements for the extinguishing arrangement (see FIG. 1).
  • these each have a cutout 6 through which the running rails 2 of the fixed contact parts 1 protrude to the outer sides.
