Definitions

  • the invention relates to a switch with an arcing chamber, in particular Medium-voltage switch-disconnector for voltages between 6 and 36 kV.
  • the knife or pin-shaped contact or switching pin is between Arranged bodies that give off gas when heated (hard gas principle).
  • the pen or knife moves when switched on and off between these bodies.
  • the arc that arises when the device is switched off builds up on the one hand by heating the air in the quenching chamber, on the other hand, due to the gas development, a pressure on the one Gas flow generated that cool and the arc as quickly as possible to delete.
  • quenching chambers for example from the German published application 195 40 552 or from German Offenlegungsschrift 195 22 852 known, which is also from the aspect of the lowest possible Space requirements were developed.
  • German Offenlegungsschrift 195 40 552 discloses one in one Post insulator integrated quenching chamber, each between the Post insulators of a pole is located.
  • the one in the extinguishing chamber Switch pin is used to switch off along a straight path of movement pulled out of the arcing chamber. This straightforward movement claims relatively much space, since at least the length by which the switching pin from the Chamber is pulled outside the arcing chamber in extension this must be kept free for the switching movements.
  • the invention is based on the problem of a pressure-resistant to withstand the required shutdown capacities To build a fire chamber that takes up as little space as possible and is as universal as possible.
  • the device according to the invention makes it possible to use switch knives in the quenching chamber so that the quenching chamber to the to meet increased performance requirements, bigger could be designed without the space required for switching knives plus extinguishing chamber has increased overall, so that despite performance increase the existing grid dimensions of the switchgear cells are observed can.
  • Existing medium-voltage switchgear can thus can be easily retrofitted with the devices according to the invention.
  • the arcing chamber according to the invention is designed such that they are for different voltages, for example for 12 and 24th kV, can be used.
  • bodies are made in a manner known per se provided gas-emitting material when heated. These can Have plate shape and when switched on against the Press the switch pin or the knife contact tip. Any other form of this Body is conceivable.
  • FIG. 1 a An extinguishing chamber 1 is shown in FIG. 1 a, which consists of a housing 2 consists of a pressure chamber 3 and an expansion chamber 4th is divided by a wall 5 with an opening 6 from each other are separated.
  • the pressure chamber 3 is located on the Expansion chamber 4 side facing a fixed contact 7th
  • the expansion chamber 4 faces the wall 5 Side an opening 8, which is also in the lower region of the Expansion chamber 4 extends and there, as it were, an additional opening 9 forms.
  • the openings 8 and 6 serve the passage of the contact tip movable switching knife 11 of the secondary flow path through the pressure 3 and the expansion chamber 4 up to the contact 7; the switch knife is held in the on position by a nose 12 which it hooked.
  • the switch blade 11 is only partially in FIG. 1a, namely with its contact tip 11a shown, the corresponding one curved shaft part 11b is connected to the pivot point B, so that the knife turns on and off along a circular path emotional.
  • extinguishing plates 10 are off when heated arranged gas-emitting material, which is acted upon by springs 21 are so that they are pressed against each other.
  • the switching knife 11 moves between them while switching on and off and touches them in the process.
  • the switch or separating knife 11 is, as the top views show, flat shaped. So that the arcing chamber meets the requirements regarding Number of shutdowns for the services mentioned (voltages and currents), it was necessary that Extinguishing chamber volume to increase what is in accordance with the invention the switch dimensions and maintaining the cell grid in surprisingly simple way is achieved that not only the Contact tip 11a dips into the arcing chamber, but at least partly also the switching or separating knife shaft 11b.
  • the extinguishing chamber despite the additional opening 9 in the expansion chamber 4 their task, namely that which arises when switching off
  • the area is to reliably extinguish an arc 9 of the opening 8, that is the additional opening in that shown in Fig. 1a, b switched off state by two flaps 14, for example Insulated, closed.
  • the Flaps 14 movably attached to the underside of the extinguishing chamber 1, at points C. They are each in the form of a Circle segment and overlap when switched off Closing the area of the additional opening 9. In a preferred embodiment they are spring loaded so that they have no outer, on they acting force assume the state shown in Fig. 1b.
  • the Extinguishing plates 10 lie one on top of the other when switched off.
  • FIGS. 3a, b This state is shown in FIGS. 3a, b.
  • the flaps 14 are now fully opened so that they release the additional opening 9. They are from the switching knife shaft 11a held in this position while the Switch knife contact tip 11a pushes the extinguishing plates 10 apart.
  • switch blades When switching off, i.e. when the switch blade 11 from the contact 12 and thus disconnected from the fixed contact 7, switch blades perform 11 and 14 flaps the reverse movement.
  • the additional opening allows for the crescent-shaped switching knife 11 that its trajectory is largely in the extinguishing chamber 1, so that with the same space requirement for the arcing chamber 1 in comparison to known quenching chambers a considerably larger chamber volume is achieved.
  • the closing speed the additional opening 9 can by the shape of the flaps 14 varies and can be adjusted specifically.
  • the measures according to the invention thus also increase efficiency the extinguishing chamber considerably.
  • FIGS. 4a, b is a further embodiment of an inventive Extinguishing chamber shown in the the embodiment 1 to 3 corresponding parts with the same reference numerals are designated.
  • the embodiment according to FIGS. 4a, b differs differs from the previously described embodiment by a another locking mechanism for the additional opening 9.
  • a plate or strip 15 is made of insulating material used. This or this is at the contact end of the arcing chamber 1 attached at 16 and closes when switched off of the switch, the complete additional opening 9.
  • the switch blade 11 presses its shaft against the plate or strip 15 the action of a spring 17 in the housing 2 towards the attachment point 16, whereby the additional opening 9 is released.
  • the Operation of this embodiment is the same as that previously described. According to the position of the switching knife 11 additional opening area 9 opened by the plate or strip 15 or closed.
  • Extinguishing plates 10 are provided made of gas-emitting material when heated.
