Definitions

  • the insulating body can be seen, for example, with at least one pressure spring, the spring force of which becomes ineffective as soon as the minimum extinguishing distance of the contacts is reached.
  • opening springs with preferably substantially less spring force than the force of the pressure spring are provided for the relative movement of the insulating material body.
  • the displaceable insulating material body is then pressed by the strong pressure spring against the force of the weaker opening springs and the pressure in the compression space onto the opening of the flow channel.
  • the insulating material body When the switch is switched on, the insulating material body is pressed against the electrode against the force of the opening springs by the pressure spring in such a way that the gas flow channels are closed.
  • the switch When the switch is opened, regardless of the pressure in the compression chamber, the gas flow channel remains closed until the electrodes that have separated have reached the minimum quenching distance. Only then does the gas flow to the extinguishing section begin, and with it the blowing of the arc.
  • the egg effect of the pressure spring can be limited, for example, by a connection and the opening springs then push the insulating body as the moving electrode continues to run, supported by the pressure in the compression space, into the open position.
  • the opening springs then, regardless of possible pressure fluctuations in the compression chamber caused by the arc, hold the insulating body in this desired blowing position until the end of the switch-off process.
  • a ratchet device can also be seen which, when the minimum extinguishing distance is reached, is unlatched, for example, via a switching cam, so that the opening springs can then push the movable insulating material body into the blowing position.
  • the extinguishing agent flow directed from the high-pressure chamber via a valve to the extinguishing path can be prevented by the displacement device until the minimum extinguishing distance is reached and only then released.
  • the pressure spring can also be brought to a halt inside the fixed contact a.
  • a driver for the insulating material body can there, for example, run in slots which determine the thrust path of the spring due to their length.
  • FIG. 1 shows a gas pressure switch, in which the insulating body is held in the closed switch position by a latch system.
  • a pressure spring 32 is arranged within the hollow cylindrical contact 2.
  • the spring travel of the pressure spring 32 is determined in this case by the pin 14 and by the right end of the slot in the contact 2.
  • the movement of the insulating material body 6 is released by a pawl system 36 which, for example, can contain a pawl 38 which can be pivoted about a shaft 39.
  • the pawl 38 is connected to a lever 40, in the end of which a wheel 41 is mounted.
  • the pawl 38 is held in the position shown by a pawl spring 42 when the switch is closed.
  • Cams 43 are provided on the inner wall of the blowing piston 8, which trigger the pawl 38 with the movement of the blowing piston 8 in a liking manner via the wheel 41.
  • the length of the fixed contact 2, with which it projects into the movable contact 4 no longer has to be designed according to the desired pre-compression ratio in the embodiment of the switch according to the invention.
  • This length is therefore only to be dimensioned such that after commutation of the current to contacts 2 and 4, a sufficient distance of the continuous current contact system, not shown in the exemplary embodiment, is achieved. This distance ensures that the such switch off.
  • the desired pre-compression ratio can be obtained by a suitable choice of the total length of the compression space. It can also be adjusted with the help of overlap valves.
