Definitions

  • the invention relates to a compressed gas switch with a gear. with racks.
  • a gear. with racks Such a switch is already known from the European patent N ° 0313813.
  • the gears of the gear to racks are placed downstream of the neck of the nozzle channeling the hot gases to the cut. This results in damage over time to this gear and the object of the invention is to remedy this drawback.
  • the invention relates to a compressed gas switch comprising a first contact part having a hollow wear contact into which a rod-shaped wear contact is introduced on closing on a second contact piece, an insulating nozzle coaxial with the two pieces of contacts and fixed on the first contact piece whose neck is, at the closure, crossed by the wear contact of the second contact part and connects a gas compression chamber to an exhaust chamber, the wear contact of the second contact part being also movable along of an axis and is moved in the opposite direction of the wear contact of the first contact piece by a rack and pinion gear arranged to transmit in opposite direction a movement from the first contact piece to the second contact part, characterized in that this rack and pinion gear is arranged upstream of the nozzle neck.
  • this rack and pinion gear is located outside the passage of the hot gases.
  • FIG. 1 very schematically illustrates a circuit breaker according to the invention in an open position at cut-off.
  • Figure 2 illustrates the circuit breaker of Figure 1 in the closed position.
  • two contact parts are shown. 1.2 respectively in an envelope, not shown, filled an insulating gas such as SF6 under a pressure of a few bars, which can be engaged in and out of each other, along a longitudinal axis 3.
  • an insulating gas such as SF6
  • These two contact parts 1, 2 have essentially a symmetry of rotation, that is to say they are essentially tubular, and comprise each respectively a permanent current contact 4 respectively 5 and a wear contact 6 respectively 7.
  • the wear contact 6 is hollow while the wear contact 7 has the form of a rod which comes to be introduced, at the cut as shown in figure 2, in the hollow wear contact 6.
  • the contact piece 1 can slide along the axis 3. The displacement of the contact piece 1 along the axis 3 is obtained by the axial translation a control rod 8 which comes out of the envelope.
  • This piece of contacts 1 includes an insulating nozzle 9 with a neck 10, arranged coaxially between permanent current contact 4 and wear contact 6 and connected rigidly to the permanent current contact 4 and to the wear contact 6.
  • the part 1 also includes an annular compression chamber 11 by piston, which can be communicated via valves unidirectional 12 formed in a ring connecting the permanent contact 4 and the wear contact 6 and by an annular channel 13 provided between the wear contact 6 and the inner wall of the insulating nozzle 9 and through the neck 10 of the insulating nozzle, with an exhaust chamber 14.
  • the annular channel 13 defines a chamber thermal compression.
  • the contact piece 1 is further surrounded by a sliding contact (not shown) and is arranged to slide in a tube metallic guide 15 mounted fixed in the envelope and along the axis 3.
  • the tube 15 carries on its outer wall of the bearings 16 and 17, the two bearings 16 being diametrically opposite with respect to the axis 3 at the two bearings 17 and each pair of bearings 16 respectively 17 serving to guide in translation the along the axis 3 a rod 18 respectively 19 secured to the part 2.
  • the permanent current contact 5 which surrounds the wear contact 7 in the form of a rod and which is integral with the latter has a tubular shape and is mounted to move along axis 3 in a tube guide 21 which is fixedly mounted in the casing which extends along the axis 3 coaxially with the tube 15.
  • the flow of current between the tube 21 and the contact of permanent current 5 is provided by a sliding contact not shown.
  • the permanent current contact 5 further comprises two protrusions 22 and 23 respectively, which extend radially outward from the tube 21 being diametrically opposite to each other with respect to axis 3, and to which the rods 18 and 19 are fixed respectively.
  • the rack and pinion gear here comprises first two racks 30 and 31 oriented parallel to axis 3 and fixed respectively on the rods 18 and 19 on the side of the contact piece 1 of such so that their teeth are oriented towards the tube 15.
  • This gear still has two second racks 32 and 33 oriented parallel to the racks 30,31 and fixed to the outer wall of the operating rod 8 inside the tube 15 so that their teeth are oriented in direction of the tube 15.
  • this gear comprises two toothed wheels 34 and 35 inserted diametrically opposite into the wall of the tube 15 with respect to to axis 3 and which can freely rotate each around a fixed axis with respect to the axis 3 and integral with the tube 15 so that the teeth of the wheels 34 and 35 respectively engage in the racks 30,32 and 31,33 respectively.
  • each toothed wheel 34 or 35 is housed in a slot arranged in the thickness of the tube 15 to engage on the one hand a rack such as 32 or 33 provided on the control rod 8 and disposed inside the tube and on the other hand a rack such as 30 or 31 provided on a rod fixed to the contact piece 2 and placed outside the tube 15.
  • this rack and pinion gear cogwheels is essentially arranged upstream from the neck 10 of the nozzle 9, that is to say out of the passage of the hot gases produced at the cutoff and represented by thick arrows in Figure 1.
  • FIG. 2 shows the circuit breaker in the closed position.
  • the contact of wear 7 is inserted into wear contact 6.
  • the contact part 1 is moved, by means of the rod 8, to the left along axis 3 and also the racks 32 and 33.
  • This movement to the left is converted by the gears 34 and 35 on the racks 30 and 31 in a movement of the rods 18 and 19 and therefore of the workpiece contacts 2 to the right made at the same speed but oriented in the direction opposite to the contact part 1.
  • the wear contacts 6 and 7 are then spaced from each other at a speed of doubled compared to the speed of movement of the control rod 8.
  • the hot gases are channeled through nozzle 9 to circulate between the contacts of permanent current 4 and 5 and wear 6 and 7.
  • Like the rack and pinion gear gear wheel is set back and upstream of the neck 10 of the nozzle 9, it is not not affected by these hot gases.
