Definitions

  • the invention relates to the field of medium voltage switch and high voltage switch technology, in particular the circuit breaker in power distribution networks. It relates in particular to a compressed gas switch according to the preamble of claim 1.
  • WO 98/43265 such a compressed gas switch.
  • This has a first, drivable arcing contact, a second, fixed arcing contact, a rated current path running concentrically therewith and a compression device in order to compress quenching gas in a blowing volume.
  • the compressed quenching gas is used to extinguish an arc resulting from the separation of the first arcing contact from the second arcing contact by blowing it with quenching gas.
  • the first, drivable arcing contact is carried by a switching tube.
  • an exhaust volume is provided, in which the quenching gas is passed after the blowing of the arc.
  • the arranged within the nominal flow path exhaust volume communicates with a low pressure space outside the nominal flow path via exhaust ports in combination.
  • the exhaust volume is separated by a partition wall of a suction, which is also arranged between blowing volume and exhaust volume within the nominal flow path. This suction is connected via a flush valve as well as a pressure relief valve with the blowing volume.
  • a flush valve as well as a pressure relief valve with the blowing volume.
  • This known gas pressure switch solves the problem that in the intake should prevail at least a nearly constant gas pressure, so that the gas pressure in the exhaust volume has no effect on the function of the purge valve as well as on the function of the pressure relief valve.
  • the dividing wall is arranged within the tube-shaped nominal flow path. Since the partition wall is exposed to a high pressure difference between the intake area and the exhaust volume during the separation of the first arcing contact from the second arcing contact, this requires a stable attachment of the partition wall to an inner wall of the rated flow path and a sealed passage of the switching tube through this partition wall.
  • Object of the present invention is to propose a compressed gas switch with a simplified design, which thereby also allows a more compact design.
  • the inventive gas pressure switch should have a high reliability, in particular the function of the pressure relief valve and / or the purge valve should not Have dependence on the gas pressure in the blow volume and on the gas pressure in the exhaust volume.
  • the compressed gas switch has a gas exchange permitting flow opening between the low-pressure chamber and a blowing volume through a region of a separating element through which separates the blowing volume from the low-pressure chamber in the radial direction with respect to the longitudinal axis of the gas pressure switch.
  • the blowing volume is connected, for example via a channel with an arc zone of the gas pressure switch through which during a first phase of a shutdown heated quenching gas, such as SF 6 , (sulfur hexafluoride) passes from the arc zone in the blowing volume.
  • a shutdown heated quenching gas such as SF 6
  • SF 6 sulfur hexafluoride
  • further phase extinguishing gas flows from the blowing volume through the channel to the arc zone to blow a burning there arc.
  • the quenching gas then flows further into an exhaust volume.
  • the blowing volume is subdivided into a compression space and into a heating space, the flow opening opening into the compression space. It can thereby be achieved that unused extinguishing gas can flow from the low-pressure chamber into the compression chamber as well as from the compression chamber into the low-pressure chamber.
  • a flush valve is arranged in or at the flow opening. It can thereby be achieved that for filling the compression space with quenching gas, this can flow from the low-pressure space into the compression space or into the blowing volume, but not in the opposite direction. Further, since the gas pressure is at least approximately constant on the side of the low pressure space, the purge valve opens at a predetermined pressure regardless of the pressure waveform during the shift operation.
  • a pressure relief valve is arranged in or at the flow-through opening. It can thereby be achieved that at a predetermined overpressure in the compression chamber or in the blowing volume, quenching gas can flow out into the low-pressure space. Since there is at least approximately a constant gas pressure in the low pressure space, the pressure relief valve opens at a predetermined response pressure. As a result, it can be achieved that no unauthorized high pressure is built up in the compression space. This can prevent that the operation of the gas pressure switch is affected due to an excessive gas pressure in the compression chamber.
  • the flushing valve and the pressure relief valve are arranged in the same or at the same flow opening. This allows a particularly compact design of the gas pressure switch as well as a simple final assembly of the gas blast switch, since the flush valve and the pressure relief valve can be pre-assembled as a unit.

  • the contact can be made instead of a contact spring, for example, via a sliding contact, a spiral contact, a sliding tulip or a roller contact. This is inserted in a circumferential groove, which is formed radially inwardly in the free end region of the conductor element 33.
  • the separator 30 is part of a well-known nominal current contact arrangement not shown in the figures.
  • the separator 30 forms a first rated current contact and is electrically connected to the first contact 14.
  • the second contact 18 is electrically connected to a second rated current contact, not shown, and is intended to cooperate with the first rated current contact, the separating element 30, when the compressed gas switch is closed.
  • a nozzle body 34 is arranged, wherein the nozzle body 34 protrudes from the separating element 30 in the direction of the longitudinal axis A.
  • the nozzle body 34 is preferably made of an insulating material, such as polytetrafluoroethylene. From the end projecting from the separating element 30, the nozzle body 34 initially has a nozzle opening 36, which tapers in the direction of the longitudinal axis A towards the first contact 14 and merges into a nozzle channel 38.
  • the nozzle channel 38 expands on the opposite side of the nozzle opening 36 to an inner diameter which is larger than an outer diameter of the contact tulip of the first contact 14, wherein the inner diameter is selected such that the contact fingers of the contact tulip have a sufficiently large game.

  • the heating chamber 46 is limited in the radial direction by the separating element 30. In the direction of the nozzle opening 36, the heating chamber is also delimited by the separating element 30 as well as by the nozzle body 34. In the opposite direction to the nozzle opening 36 of the heating chamber 46 is bounded by an intermediate wall-like intermediate member 48.
  • the first contact element 14 is guided tightly through the intermediate element 48.
  • the intermediate element 48 is preferably held on the separating element 30 in a form-fitting manner. It may also be positively secured to the first contact 14.
  • an interior of the separating element 30 is subdivided into the heating space 46 and into a compression space 52.
  • the compression space 52 is limited on the side opposite the intermediate element 48 by a piston 56, which is arranged stationary in the present case.
  • the piston 56 is part of a cylinder-piston arrangement, wherein the cavity of this cylinder-piston assembly is formed by the compression space 52.
  • the piston 56 has a passage opening for the first contact 14. Between the piston 56 and the first contact 14 is a seal 80 in a recessed groove in the piston inserted to seal a gap between the first contact 14 and the piston 56. Furthermore, the seal 80 also forms a guide for the first contact 14. The piston 56 is sealed against the separating element 30 by means of a further seal 82, which is inserted into a further circumferential groove in the piston 56.
  • an exhaust volume 58 On the opposite side of the compression chamber 52 of the piston 56 is located within the conductor element 33, an exhaust volume 58. This is connected by a pipe 12 formed in the flow channel 59 with the arc zone 40, so that extinguishing gas, which from the heating chamber 46 through the gas passage 44 into the Arc zone 40 flows through the flow channel 59 can flow into the exhaust volume 58. During a high-current phase, quenching gas can also flow directly from the arc zone 40 into the exhaust volume 58.
  • a channel 60 which is closable by a designed as a check valve intermediate valve 62 so that at an overpressure in the compression chamber 52 relative to the heating chamber 46 quenching gas from the compression chamber 52 flows into the heating chamber 46.

  • the low-pressure chamber 72 is bounded by a sheath, not shown, of the gas pressure switch and connected via a gas return to the exhaust volume 58.
  • the flushing passage 66 can be closed in such a way by means of a flushing valve 74 designed as a check valve, so that at a negative pressure in the compression chamber 52 relative to the low-pressure chamber 72 the flushing valve 74 opens and otherwise closes.
  • the overpressure passage 68 can be closed by means of a pressure relief valve 76, which opens at a defined overpressure in the compression chamber 52 relative to the low pressure chamber 72 in order to build off any overpressure in the compression chamber 52.
  • flushing passages 66 can also be provided which can each be closed by means of a flushing valve 74.
  • a plurality of overpressure passages 68 may be provided, each of which can be closed by means of a pressure relief valve 76.
  • the in Fig. 1 shown gas pressure switch works as follows. First, the rated current contact arrangement is opened. Subsequently, the contact arrangement formed by the first contact 14 and the second contact 18 is separated, whereby an arc in the arc zone 40 ignites due to the current flow through the contact arrangement. As a result, quenching gas is heated. This flows initially through the gas passage 44 in the heating chamber 46. When opening the contact arrangement is also by the movement of the separating element 30 together with the first contact 14 in Direction of the longitudinal axis A away from the second contact 18 of the compression space 52 reduced, whereby the gas pressure in this increases.
  • the gas pressure in the compression chamber 52 is greater than in the heating chamber 46, opens the intermediate valve 62, whereby quenching gas flows through the channel 60 from the compression chamber 52 into the heating chamber 46 and further increases the gas pressure in this. As soon as the gas pressure in the arc zone 40 decreases, quenching gas flows from the heating chamber 46 through the gas channel 44 into the arc zone 40 and inflates the arc, which is thereby extinguished.
  • the gas pressure in the heating chamber 46 rapidly increases to a high value, the situation may arise that the intermediate valve 62 remains closed in the heating chamber 46 during the separation process of the contact arrangement, or at least over a longer Period of time during the separation process is closed. As a result, the extinguishing gas from the compression chamber 52 does not flow into the heating chamber 46. Upon reaching a predetermined gas pressure in the compression volume 52 now opens the pressure relief valve 76, which quenching gas can flow through the pressure passage 68 into the low-pressure chamber 72.
  • the maximum pressure in the compression space 52 is defined by the response pressure of the pressure relief valve 76. It can thereby be achieved that a force necessary for opening the contact arrangement, in particular for retracting the separating element 30 together with the first contact 14 into the conductor element 33, does not exceed a maximum force. Thereby, the drive arrangement can be designed such that the contact arrangement can be reliably separated even at high current flow.
  • the quenching gas used to blow the arc in the arc zone 40 flows on the one hand through the flow channel 59 into the exhaust volume 58 and on the other hand through the nozzle opening 36 from. In the exhaust volume 58, the hot quenching gas is cooled. A gas exchange between the exhaust volume 58 and the low pressure space 72 can take place via a not shown gas recirculation.
  • the volume of the compression chamber 52 increases, whereby in this compared to the low-pressure chamber 72 as well as to the heating chamber 46, a negative pressure.
  • the purge valve 74 opens, which releases the purge passage 66 for the flow of quenching gas from the low-pressure space 72 into the compression space 52.
  • the purge valve 74 closes.
  • the overpressure valve 76 on the overpressure passage 68 is dispensed with. Nevertheless, due to the clear diameter of the overpressure passage 68, the quenching gas flow can be controlled by the overpressure passage 68, in particular with an overpressure in the compression space 52 relative to the low-pressure space 72. Thus, upon disconnecting the first contact 14 from the second contact 18 while simultaneously reducing the volume of the compression space 52, quenching gas may flow out of the compression space 52 into the low pressure space 72. Consequently, the gas pressure in the compression space 52 can not increase arbitrarily.
