Definitions

  • the invention relates to an erosion switching arrangement especially for circuit breakers like those in power plants, Substations and other facilities of the Electrical energy supply for switching on and off Operating and overcurrents are used.
  • the invention has for its object a Specify burn-up switching arrangement in which the Switching elements mechanically not even at high currents be overloaded and there is no excessive contact pressure.
  • Switch axis 1 is approximately rotationally symmetrical.
  • a switching pin 2 with a Tip 3 made of fire-resistant material such.
  • a first contact piece comprises a ring of arranged around the switching axis 1, radially directed against the same contact elements as elongated contact fingers 4 are formed, which on their Wear ends of erosion heads 5 made of erosion-resistant material.
  • the contact fingers 4 together form an approximately circular contact part, the against the Switch axis 1 directed contact surfaces of the erosion heads 5 one in the on position on the outside of the Represent switching pin 2 adjacent contact zone. From Abbrandkopf 5 apart from each contact finger 4 is in one piece with a 90 ° turn in the switch-on direction, so with the contact finger 4 a right angle including web 6 made of highly conductive spring-elastic Material made and fixed to a housing part 7 anchored, via which the web 6 with a first electrical Connection is connected.
  • the switching pin 2 forms against it a second contact piece, the z. B. via a flexible Line or a sliding bell with a second electrical Connection is connected.
  • a support body 8 is located in an opening of the housing part 7 attached from electrically insulating material, the cylindrical outer surface forms a support surface 9, on which the webs 6 rest in the off position.
  • the contact fingers 4 by the Contact of the erosion heads 5 with the peripheral surface of the Switch pin 2 deflected radially outwards under elastic deformation of the webs 6, which of the Support surface 9 are lifted.
  • the initial deflection can be quite because of the high elasticity of the webs 6 be chosen large, so that a large burn-up reserve for Available.
  • the support body 8 has a Opening, which is a nozzle surrounding the switching axis 1 10 forms, in which the tip 3 in the switched-on position of the switching pin 2 protrudes.
  • the length L of the same can be set that the mutual attraction of the contact fingers 4 in the Current levels to be expected due to the elastic deflection of the contact fingers 4 of the same contact pressure exerted against the switching pin 2 desired way reinforced and especially the between these parts effective contact lifting forces compensated. Such compensation remains above all Fluctuations in amperage received because Contact lifting and attraction forces in the same way depend on the same.
  • the burn-up switching arrangement shown in FIG. 2 corresponds to what the first contact piece concerns completely the first Embodiment.
  • the second contact piece comprises in addition to switching pin 2, an erosion contact arrangement, which in turn corresponds exactly to the first contact Contact fingers 4 'with erosion heads 5' which in the Switch on position with a second contact zone forming inner surfaces against the peripheral surface of the Press the switching pin 2, the contact fingers 4 'in turn Connect to webs 6 'angled by approx. 90 ° and over the same and a housing part 7 'with the second electrical connection are connected so that the Contact finger 4 'also functions as a sliding tulip perceive.
  • the webs 6 ' are in the off position again on a support surface 9 'from the outside a support body 8 'is formed, which is also a forms the switching axis 1 surrounding nozzle 10 '.
  • the erosion switching arrangement according to that in FIG. 3 illustrated third embodiment of the invention otherwise corresponds completely to that according to the second Embodiment, but the contact fingers 4, 4 'are each Burning rings 12, 12 'prescribed. They form parts of pot-shaped shields 13, 13 'which, with the webs 6 or 6 'connected in an electrically conductive manner, in each case the rest Surround parts of the contact pieces and completely shield them.
  • the arc 11 When switched off, the arc 11 commutates rapidly the erosion heads 5 of the contact fingers 4 on the erosion ring 12, while it from the tip 3 of the switching pin 2 in essentially commutates on the erosion ring 12 ', which the Burning of the contact fingers 4, 4 'is reduced and thus theirs Lifespan increased.
  • the support body 8 forms a support surface 9 in the shape of a truncated cone, which lies at a distance below the contact fingers 4 and limits their mobility against the switching axis 1.
  • the course of a switch-off corresponds to that described in connection with the erosion switching arrangement according to the first embodiment of the invention.
  • the basic structure corresponds to that of the Burn-up switching arrangement according to the first embodiment of the Invention.
  • contact fingers are however as Contact elements contact pieces 4 "provided preferably exactly radially displaceable in corresponding radial recesses 14 open against the switching axis 1 a retaining ring 15 surrounding the same are stored, which is attached to the housing part 7 and the same with the first electrical connection electrically connected and which also forms the nozzle 10.
  • the retaining ring 15 is otherwise solid and consists of electrical conductive material.
  • the contact pieces 4 "only protrude at least on their front ends of erosion-resistant tips 17 through corresponding openings in the panel 16, while the same a stop for the front shoulders of her form wider body 18.
  • the electrical contact with the Retaining ring 15 is made by contact lamellae 19.
  • the contact piece is 4 " each with a radially acting against the switching axis 1 Force applied.
  • the first contact piece as rigid first switching ring 25 made of erosion-resistant material trained, which is fixed in the housing and over the same also electrically conductive with the first electrical Connection is connected.
  • the second contact piece comprises a switching pin 2, which, in a switch-off direction supported limited compressible disc spring package 26, is axially slidably attached to a bracket 27 which by a switching drive, not shown, along the Switch axis 1 can be moved, as well as a contact part, that as an annular disc 28 made of highly conductive resilient material, e.g. B. CuBe or CuCrZr is trained.
  • each of the sectors 31 of the circular disc 28 carries on its inner edge a made of fire-resistant Material existing sector 32 of a second switching ring 33.
  • Via the housing part 7 is the outer ring 29 with which second electrical connection electrically connected.
  • the switching pin 2 has, compared to its tip by about Distance between the first switching ring 25 and the second Switch ring 33 offset in the switch-off direction, a rotating one Shoulder 34 on.
  • the top is in the ON position of the switching pin 2, from the compressed disc spring package 26 with sufficient contact pressure at which Front of the first switching ring 25 all around, while the Shoulder 34 against a contact zone on the second switching ring 33 presses and the sectors 32 of the same under elastic Deformation of the sectors 31 of the circular disk 28 axially in Switching direction deflects slightly, so that through the elastic restoring forces of the sectors 31 also here there is sufficient contact pressure.
  • the burn-up switching arrangement shown schematically in FIG. 9 according to a ninth embodiment of the invention is similar to the one described above.
  • the first switching piece as from the inside Edge slotted first circular washer 35 highly conductive resilient material.
  • the Switch pin 2 is rigid on a not shown a shift actuator displaceable along the shift axis 1 Bracket attached and a sliding tulip 36 with the second electrical connection electrically connected.
  • the elastic restoring force of the first circular disc 35, the inner edge 37 of a fire-resistant material easy in the switch-on position axially in the switch-on direction deflected contact zone provides a sufficient Contact pressure safe.
  • the second switching piece includes one with the second electrical connection is electrically conductive connected rigid second circular washer 38 erosion-resistant material whose inner diameter only is slightly larger than the diameter of the Switch pin 2. It acts as a burn ring, on the Switch off the one arc base point from switching pin 2 skips.
