Definitions

  • the invention relates to a gas pressure switch with two Switch pieces, between those in the switched-off state there is a switching path with a Insulating nozzle in the area of the switching path is provided with a gas storage space that is adjacent is provided to the insulating nozzle, and the one including the channel formed by the insulating nozzle the switching path is connected, and with an intermediate wall inside the gas storage room.
  • Such a pressure gas switch is from DE 39 15 700 C3 known.
  • right part of DE 39 15 700 C3 shows that the intermediate wall 10 is radial aligned webs on the cover 6 and in the material 4 is attached.
  • the on the Intermediate wall 10 attached webs must e.g. in Snap the existing holes in the cover 6 to one To achieve attachment of the intermediate wall 10. After that must the material 4 are installed, where appropriate. again the webs of the intermediate wall 10 in the holes Material 4 must be fixed.
  • the object of the invention is to provide a gas pressure switch create that enables easier production.
  • This task is the beginning of a gas pressure switch mentioned type according to the invention solved in that the The partition is connected to the insulating nozzle.
  • the partition is no longer necessary with corresponding effort e.g. on the cover too Fasten. Instead, the partition is simpler Way connected to the insulating nozzle so that it automatically with the insulating material nozzle inside the Pressure gas switch is fixed. One with an effort connected, separate attachment of the partition is not necessary anymore.
  • the partition and the insulating nozzle integrally formed. This also eliminates assembly the partition and the insulating nozzle in front of them common installation in the pressure gas switch. Instead the one-piece component can be instantly integrated into one Work step can be installed in the gas pressure switch.
  • the partition with fasteners, preferably by means of a snap connection, with the insulating material nozzle connected. This enables a particularly simple and quick assembly of the partition and the Insulating.
  • the partition wall is made of an insulating material, preferably made of Polytetrafluoroethylene (PTFE), which may be is provided with a filler. In this way, one particularly effective cooling of the gas storage space introduced heated extinguishing gas reached.
  • PTFE Polytetrafluoroethylene
  • a gas pressure switch 30 is shown, the provided for switching an electrical high voltage is.
  • the gas pressure switch 30 is largely rotationally symmetrical, which is why only in the figure the right half of the pressure gas switch 30 is shown.
  • the gas pressure switch 30 has two contact pieces 1, 2, of which the one contact 1 as a contact pin and that other contact 2 is designed as a tulip contact.
  • the Switch pieces 1, 2 are made of electrically conductive material manufactured.
  • the two contact pieces 1, 2 are in their shown open state in which no electrical Connection exists between them.
  • the two contact pieces 1, 2 are coaxial with one another aligned and can move in opposite directions to each other become.
  • the contact pin dips into the Tulip contact so that an electrical connection arises.
  • the direction of movement of the two Switch pieces 1, 2 becomes the longitudinal axis of the pressure gas switch 30 set.
  • the Insulating material nozzle 5 consists of polytetrafluoroethylene (PTFE) or other insulating material.
  • the tulip-shaped switching piece 2 is of a surrounded cylindrical cover 6, which is also made of PTFE or other insulating material. Between the insulating nozzle 5 and the cover 6 is a Channel 7 formed, which is curved by about 90 degrees has, and the switching path with a Gas storage room 3 connects.
  • the gas storage space 3 is on the one hand in the radial direction through the cover 6 and on the other hand by a coaxially arranged, cylindrical jacket 4 limited.
  • the jacket 4 is made of metal and on its Isolierstoffdüse 5 end facing it as Rated current contact piece 27 is formed. At this end lies the jacket 4 with its radially inner surface on the radially outer surface of the insulating material nozzle 5.
  • the pin-shaped switching piece 1 is one metallic current contact 26 coaxially surrounded, the in the closed state of the pressure gas switch 30 with the Nominal current contact piece 27 an electrical connection forms.
  • the gas storage space 3 is through a Floor 25 limited.
  • the cover 6 With its end facing away from the channel 7 Investment.
  • the bottom 25 is radial outer edge on the inner surface of the jacket 4.
  • the gas storage space 3 is toroidal formed and coaxial to the longitudinal axis of the Compressed gas switch 30 arranged.
  • an outflow channel 8 which is within a tube runs.
  • the tube is coupled to a switch drive, the for moving the two contact pieces 1, 2 and thus provided for switching the pressure gas switch 30 is. With the tube are the tulip-shaped contact 2 and the gas storage space 3 with the insulating nozzle 5 and the Cover 6 firmly connected.
  • the intermediate wall 10 is cylindrical formed and arranged coaxially to the longitudinal axis.
  • the Intermediate wall 10 extends in the longitudinal direction of the Gas storage space 3 and thus in the longitudinal direction of the Gas pressure switch 30.
  • the partition 10 begins on the the gas storage space 3 facing end region of the Isolierstoffdüse 5 and ends above the bottom 25th
  • the partition 10 can be non-cylindrical Have shape, e.g. can the Partition 10 have a conical shape.
  • the intermediate wall 10 is in one piece with the insulating material nozzle 5 trained.
  • the PTFE or the other material be provided with a filler.
  • the intermediate wall 10 as separate component made of an insulating material is produced and for example by means of a Snap connection or the like directly with the Isolierstoffdüse 5 is firmly connected.
  • the intermediate wall 10 is adjacent at its upper end to connect them to the insulating nozzle 5 one or several openings 11.
  • the openings 11 can be e.g. are holes that are within the scope of the cylindrical partition 10 at intervals are arranged.
  • the intermediate wall 10 in its in the longitudinal direction central area with further openings 9 be provided. Since the partition 10 above the floor 25 ends, is between this end of the partition 10 and the bottom 25 has a circumferential gap-shaped opening 12 available.
  • the intermediate wall 10 divides the gas storage space 3 into one Inflow part space 13 and an outflow part space 14 Inflow subspace 13 is via the area 15 with the channel 7 connected.
  • the outflow part space 14 is over the area 16 and the openings 11 connected to the channel 7.
  • the Inflow part space 13 and outflow part space 14 are in their lower area with each other via the opening 12 connected.
  • the intermediate wall 10 can on both surfaces with be provided at least one circumferential collar 17, the e.g. in the form of different wall thicknesses, i.e. one Thickening or thinning of the wall thickness of the partition 10 is formed in the radial direction.
  • Bund 17 can the gas flow through the Einströmteilraum 13th and / or the outflow part space 14 can be controlled.
  • the partition can be on both surfaces be provided with at least one groove and / or a web, which are aligned in the longitudinal direction (not shown). In this way, the one formed by the intermediate wall 10 Area to be enlarged.
  • the arc heats the extinguishing gas in the area of the Switching path.
  • the extinguishing gas expands and penetrates through the Channel 7 in the gas storage room 3. This is in the figure marked with arrow 18.
  • the heated extinguishing gas is also cooled in that the gas flowing into the gas storage space 3 first in the longitudinal direction along the entire cover 6 and then guided along almost the entire jacket 4.
  • the heated extinguishing gas flows in twice at the same time along the entire partition 10, which is due to the insulating material of the intermediate wall 10 also a Cooling causes.
  • partition 10 is a separate one Component, so the partition 10 with the Isolierstoffdüse 5 connected. This can e.g. by a Snap connection made. Then again in one single operation that from the partition 10 and the Isolierstoffdüse 5 existing component from below in the Compressed gas switch 30 installed. So remains in the case a separate partition 10 the advantage of installation of partition 10 and insulating nozzle 5 in one received a single operation.
