Definitions

  • the invention relates to a circuit breaker, as in Power plants, substations and other facilities of the Electrical energy supply for switching on and off Operating and overcurrents are used.
  • Fuses are also known in which an electrical Connection through the explosion of an explosive charge is separated.
  • DE-A-35 37 314, for example, is one Fuse described with a tubular, central constricted and surrounded by a pressure chamber Bridge ladder, one on the outside in the pressure chamber Explosive charge is attached all around.
  • the pressure chamber is lined with a material that after ignition of the Explosive charge and blasting of the bridge ladder under the Influence of an electronegative arc Gives off gas along with those from the explosion generated a high-pressure extinguishing gas forms that while blowing the arc into one Expansion space flows out.
  • extinguishing gas forming powder in fuses is also from the EP-A-0 657 910 and EP-A-0 641 005 are known.
  • the invention is based on the object Generic circuit breaker to improve such that the arc is exposed to a strong flow of quenching gas without causing an additional burden on the Shift actuator leads.
  • Fig. 1 in the on position Abbrandschaltan extract shown a circuit breaker according to a first embodiment of the invention fixed first contact piece, which as Contact tulip 1 is designed with resilient contact fingers, which surrounds a switching axis 2.
  • a switching pin 3 is provided along the Switch axis 2 between the switch-on position shown and a switch-off position in which he is behind him in the contacting sliding tulip 4 withdrawn, convertible.
  • an arc room 5 Between the contact tulip 1 and the sliding bell 4 is an arc room 5, which in the switch-on position is occupied by switching pin 3 and is surrounded on all sides by a pressure chamber 6.
  • Arc chamber 5 and the pressure chamber 6 are over a annular blow opening 7 connected.
  • the circuit breaker can also not shown rated current contacts have, which in each case before switching off Contact pieces of the erosion contact arrangement are separated.
  • a charge 10 is on the outer wall of the pressure chamber 6 Arranged explosive, which partially fills the same and at least under certain circumstances with one Switch off is ignited. There can also be a plurality of charges distributed over the circumference of the pressure chamber 6 be provided.
  • the load 10 can in any case be pressed into Tablet form or cartridge-like in one Powdered explosive case. This can have the most diverse compositions. He should however, when it exploded into reaction products are implemented, at least predominantly for Arc extinguishing are suitable. In order to avoid Environmental pollution is nitrogen as the extinguishing gas prefers.
  • explosives which are harmless to the environment and whose reaction products have a high proportion of nitrogen are known, above all, from so-called airbags, which are widely used as safety devices in motor vehicles, and are also suitable for use in switches according to the invention.
  • An example is 21NaN 3 + KNO 3 + 4Fe 2 O 3 + 2.5SiO 2 , which is converted into 10.5Na 2 O + 0.5K 2 O + 4Fe + 2.5SiO 2 + 4FeO + 32N 2 during the explosion.
  • This explosive contains no halogens and is otherwise environmentally friendly, so that the exhaust volumes 8a, b can also be open.
  • a suitable explosive is a mixture of 71.6% SrNiO 3 , 3.77% V6MO15O60, 3% paraffin, 21.6% guanidine-5,5'-azotetrazolate, in 8.2% CO 2 , 31 , 1% H 2 O, 43.7% N 2 and 15.6% SrCO 3 is reacted.
  • the switching pin 3 When switching off, the switching pin 3 is by a Switching drive, not shown, moves down, wherein he the exhaust 9a, the arc room 5 with the first Exhaust volume 8a connects, releases. Between the Switch pin 3 and the contact tulip 1 is a Arc drawn when the tip of the switch pin 3 the sliding bell 4 passes, commutated to it, so that it burns between the contact tulip 1 and the sliding tulip 4. The switching pin 3 is moved further down until it Exhaust 9b between the arc room 5 and the second Exhaust volume 8b releases.
  • the Charge 10 ignited, whereupon the contained therein Explosive in a very short time - approx. 10 to 30 ms, usually at most 50 ms - converted to gas that has a high proportion of extinguishing gas - in the above example given nitrogen - contains.
  • the gas yield is usually at least 0.2 l / g, usually 0.5 to 1 l / g, so that a high pressure in the pressure chamber 6 very quickly Pressure is built up, which then turns into a strong one Gas flow from the pressure chamber 6 via the arc chamber 5 and the two exhausts 9a, b into the two exhaust volumes 8a, b discharges.
  • the arc is blown intensively and deleted.
  • the Charge 10 can also be ignited by a separate ignition device are triggered, which on appropriate Appeals to criteria.
  • This offers the possibility of a Trigger only when the current is a exceeds certain threshold, e.g. B. 10 times the rated current reached if there is no blowing below the threshold is necessary or a weak one, for low fault currents adequate blowing by other means is provided.
  • An ignition of the charge 10, which is a reloading can be limited to those cases in which it is really necessary.
  • Another way with which an elaborate Reloading mechanism can be avoided is one layer-by-layer assembly of the loads of the Explosive. Between the individual layers of the Explosives are layers of an electrically insulating Material of defined strength for spatial separation the same provided. Under the influence of an arc evaporates the top layer of the insulating Material and so gives the next layer of explosive free, which is then ignited and burns off to form gas. This Ignition is usually through the arc, there are however, other ignition mechanisms are also conceivable. At a particularly powerful and long-burning arc can evaporate several layers in succession and burn down. This arrangement of the explosive has the special advantage that the gas generation over a is distributed over a longer period of time, making a special one intense and long-lasting blowing of the arc is achieved.
  • a circuit breaker according to the invention can also with a conventional, on low fault currents designed circuit breakers are placed in series, the the interruption of them until a certain one Amperage takes over while turning off the Circuit breaker according to the invention only triggered when a higher fault current occurs.
  • FIG. 2 Burn-up switching arrangement of an inventive Circuit breaker according to a second embodiment corresponds in its basic structure to that according to the first embodiment.
  • the Description of the latter referenced he points additionally several on the switch-off side to the pressure chamber 6 subsequent, surrounding the switching axis 2 and to the same parallel cylinder 11, in which with the switching pin 3rd firmly connected pistons 12 are arranged displaceably.
  • the pressure build-up affects Pressure chamber 6 also in that the pistons 12 in the Cylinders 11 with a force acting in the switch-off direction be charged. This causes or supports the Switch-off movement of the switching pin 3.
  • the charge 10 continue to exist above described possibilities. It can be done first by one mechanical drive of the switching pin 3 so far against the Switch off position to be moved until there is an arc forms, which is sufficient for triggering the ignition. The on the piston 12 acting force then only supports a part the switch-off movement. In addition, the ignition can also are triggered otherwise, e.g. B. if the Switch pin 3 is still in the ON position.
  • FIG. 3 Burn-up switching arrangement of an inventive Circuit breaker according to a third embodiment essentially corresponds to that according to the first embodiment. But is only one arranged on the switching side, with the arc space above an exhaust 9 connected exhaust volume 8 is present, while on the switch side of the arc room 5 and with the same over a round surrounded by the contact tulip 1 Blown opening 7 connected, a pressure chamber 6 with a load 10 is arranged. In the on position, the Switch pin the exhaust 9 and with its tip also the lower part of the blow opening 7 in cross section completely out.
  • the arc chamber 5 is of an annular shape Surround heating volume 13, which is open to the same.
  • the pressure chamber can also be relatively small and be completely filled by the cargo.
  • the heating volume can be dispensed with if the load is so dimensioned that the one generated when it is ignited Extinguishing gas flow for quenching the arc safely is sufficient.
