Definitions

  • the inventions relate to autopneumatic gas pressure switches according to the preamble of one of claims 1 to 4.
  • the plasma located in the space between the insulating nozzle and mating contact acts in such a way that transient voltages with large voltage values can no longer be maintained, because plasma between the conductive surfaces of the moving parts of the switching section pump and the fixed contact piece of the switching section provides the possibility of re-ignition given is.
  • the invention has for its object to provide a switch in which an optimally effective and structurally simple shielding is provided.
  • the gas space in which the arc cloud and the fixed counter contact are located is thus directly separated from the other spaces in which the conductive surfaces of the moving contact system are located, so that the ability to re-ignite is greatly reduced, i.e. the dielectric strength is greatly increased. It is therefore not the individual parts that are shielded individually, but rather the gas space in which the arc cloud is located.
  • the cylindrical part can be an insulating tube, but also a metal tube.
  • An externally metallized insulating tube is also conceivable.
  • a pressure gas switch in which a nominal current path is provided in addition to the power contact pieces between which the arc burns, a nominal current path is provided in order to increase the nominal current, the arrangement is expediently such that the contact transition point between the contact pieces of the nominal current path with respect to the arc radiation and the main part of the fission products is shielded.
  • the contact pieces of the nominal current path are arranged outside the insulating tube according to a further feature of the invention, so that the contacts of the nominal current path do not have a performance-reducing effect.
  • the above-mentioned partitioning of the gas spaces also greatly reduces the risk of reignition between the contact pieces of the nominal current path when switching large currents.
  • this metal tube expediently forms a contact piece of the nominal current path, the other contact piece of which encompasses the metal tube on the outside.
  • the partition is expediently largely gas-tight so that the arc gases cannot escape between the insulating nozzle and the cylindrical part.
  • a nominal current path is electrically connected in parallel with the power current path formed from the power contact pieces, an insulating shield in the form of an insulating tube and an insulating piston being provided for the movable contact piece of the nominal current path, in order to avoid the risk to avoid re-ignition between the nominal current contacts when switching off higher currents.
  • the other, fixed contact piece of the nominal current path is, however, exposed relatively unprotected to the arc radiation and the arc gap products in this known pressure gas switch, even if the outer shape of the insulating nozzle provides a certain protection. In this known switch, the contact point between the contact pieces of the nominal current contact can be adversely affected when switching high currents.
  • a shield provided for the task is to be created, so that the contact point between the rated current contact pieces is not adversely affected by the arc.
  • the shield is advantageously designed and arranged in a pressure gas switch that has an insulating nozzle, so that it at the same time surrounds the space into which the arc gases flow, the shielding having a cylindrical part within which the insulating nozzle, which has a correspondingly configured shield, is guided in a sliding manner.
  • the above-mentioned shielding ensures in particular that the contact point between the contact pieces of the nominal current path is not adversely affected when high currents are switched off.
  • the shield can be formed by a metal tube or else by an insulating tube. In the case of a metal tube, this is expediently designed directly as a contact piece of the nominal current path, which is contacted externally by the other contact piece.
  • the cross sections of the cylinder can be reduced, which results in the desired reduction in the moving masses.
  • the cross sections of the fixed contact pieces can be generously dimensioned so that large nominal currents can be transmitted.
  • the solution according to the invention also offers good cooling options.
  • the switch designed according to claim 4 has a fixed contact piece which is conductively connected to the movable part of the piston / cylinder arrangement.
  • This switch can have an upper plate-shaped electrical connection and a lower plate-shaped electrical connection.
  • the power path of the switching path can be determined by a fixed power contact pin, which is conductively connected to the upper connection plate, in connection with a movable power contact, the arcing contact, are formed.
  • This movable power contact is conductively connected to a movable cylinder which interacts with a fixed piston, which is attached to the lower connecting plate, as a switching section pump for generating the required blowing pressure in the event of a switch.
  • the movable piston can be conductively connected to a fork for the introduction of current and force, which in turn is connected to a drive rod.
  • the drive rod can be actuated by a hydraulic or pneumatic spring drive or the like, whereby it is guided inside of supports, on the lower end of which the drive is attached.
  • the fork can be in conductive connection with the lower connection plate via high-current contacts.
  • a parallel nominal current contact path can be provided, to increase the current carrying capacity, consisting of two cylindrical contact pieces.
  • the upper parallel contact piece is then conductively connected to the upper connection plate and is fixed.
  • the lower parallel contact piece is conductively connected to the movable cylinder and is therefore moved together with the cylinder.
  • the nominal current contact path is coordinated with the power current path in such a way that it opens shortly before the power current path is opened, so that the arc is only in the power current path.
  • the switch is limited in its current carrying capacity.
  • the aim is therefore to achieve a higher current carrying capacity with a switch with a shield that is as simple as possible.
  • the powerful cylinder is used to carry the current; Because of the large mass of the cylinder and the fixed tube, there is a very high current carrying capacity with little effort.
  • the arrangement is expediently such that the contact transition point between the contact pieces of the nominal current path with respect to the arc radiation and the essential part of the fission products is shielded. By sealing off the gas compartments, the risk of reignition between the contacts of the nominal current path when switching large currents is also greatly reduced.
  • the cylindrical part is a metal tube, this metal tube expediently forms a contact piece of the nominal current path, the other contact piece of which encompasses the metal tube on the outside.
  • the insulating nozzle In order to get the required electric shock distance between the metal tube and the cylinder, which is possible by shortening the metal tube, the insulating nozzle must be relatively long in this design and is consequently difficult. The insulating ability of the insulating nozzle can also be further improved.
  • FIG. 1 shows a switch pole of an autopneumatic high-voltage compressed gas circuit breaker.
  • the contact system is arranged within an insulator 1 in a closed switching chamber.
  • the switch has an upper plate-shaped electrical connection 2 and a lower plate-shaped electrical connection 3.
  • the power path of the switching path is formed by a fixed power contact pin 4, which is conductively connected to the upper connection plate 2, in connection with a movable power contact, the arcing contact 5.
  • This movable power contact. 5 is conductively connected to a movable cylinder 6, which cooperates with a fixed piston 7, which is attached to the lower connection plate 3, as a switching path pump for generating the required blowing pressure in the event of a switch.
  • the movable piston 6 is conductively connected to a fork 8 for the introduction of current and force, which in turn is connected to a drive rod 9.
  • the drive rod is actuated in the usual way by a hydraulic, pneumatic spring drive or the like; it is guided inside supports 10, at the lower end of which the drive is attached.
  • the fork 8 is in high-current contacts 11 with the lower connection plate 3 in a conductive connection.
  • An insulating nozzle 12 is fixedly connected to the movable piston 6 in the area of the movable power contact 5, from which the gas compressed in the switching section pump 6, 7 emerges when it is switched off and blows on the switching arc which is between the power contacts 4, 5.
  • This insulating nozzle 12 has a screen 13 which is slidably guided in a fixed insulating material cylinder 14 connected to the upper connecting plate 2.
  • the transition between the insulating material cylinder and the screen 13 is expediently gas-tight.

  • a parallel nominal current contact path is provided to increase the current carrying capacity, consisting of two essentially cylindrical contact pieces 16 and 17.
  • the upper parallel contact piece 16 is conductively connected to the upper connection plate 2 and is fixed.
  • the lower parallel contact piece 17 is conductively connected to the movable cylinder 6 and is thus moved together with the cylinder 6.
  • the nominal current contact path is coordinated with the power current path in such a way that it opens shortly before the power current path is opened, so that the arc is only in the power current path.
  • the parallel path required for carrying larger nominal currents between the insulator 1 and the insulating tube 14 on the one hand and the insulating nozzle is provided with a screen 13 which is sealed off from the insulating material cylinder 14, so that a separated gas-tight space 20 is electrically insulated to the side and to the bottom arises, in which the arc plasma cloud is after switching off, the re-ignition ability between the conductive parts 4 and 6 of the power current path and in particular also the contacts 16, 17 of the parallel nominal current path is enormously reduced, ie the additional conductive surfaces of the parallel nominal current path also do not reduce the breaking capacity.
  • the illustrated embodiment of the invention enables the construction of autopneumatic high voltage circuit breakers that can switch high currents at high voltages, i.e. have a high breaking capacity.
  • the insulating nozzle or its screen it is essential that the space 20 in which the plasma cloud occurs is largely sealed by the cylinder 14 and the screen 13, if necessary with the aid of sealants, such as e.g. Sealing rings 15. This reduces the re-ignition ability, i.e. the dielectric strength increases enormously. If the requirements for dielectric strength are lower, the requirements for gas tightness can be kept lower.
  • sealants such as e.g. Sealing rings 15.
  • the corresponding contacts can be cylindrical or also web-shaped as individual contacts. It is essential that, if they are provided, they are shielded from the cylinder 14 from the space 20 with the plasma cloud, both against the arc radiation and against the precipitation of the essential part of the fission products, so that the contact point is not affected by the arc.

  • This insulating nozzle 12 has a screen 13 which is slidably guided in a fixed insulating material cylinder 14 connected to the upper connecting plate 2.
  • a metal tube can be provided instead of the insulating material cylinder 14, which directly forms the nominal current contact piece, as a result of which the diameters can be kept small.
  • a parallel nominal current contact piece 216 is provided between the insulating material cylinder 14 and the insulator 1, that is to say in a space 20 which is shielded from the plasma cloud generated by the arc, in order to increase the nominal current carrying capacity.
