Definitions

  • the invention relates to an extinguishing chamber consisting of a ' tubular housing, a guided in this housing, telescopically extendable against the force of return springs arrangement of extinguishing tube and switching pin, and a controlled depending on the extension path of the extinguishing tube locking device between the extinguishing tube and switching pin.
  • Quenching chambers of this type are generally known and are in large numbers in practical use.
  • the latching device provided between the quenching tube and the switching pin and which triggers after a predetermined quenching tube advance consists of spring-loaded latch arrangements which interact with inclined surfaces or cams. Flawless operation must be required from these locking devices, since faulty switching can only be avoided if exact triggering and release times are guaranteed. An early release of the latching is particularly critical, since in this case the required distances of the main current path. are not guaranteed.
  • the specification of a defined trigger point of the latching device is particularly critical with regard to the required long-term operation, since both the respective spring preloads and the accuracy of the respective grooves or cams affect the setting of the trigger point and, for example, both during production and Burr formation or signs of wear can occur in later operation, which severely affects the functionality.
  • the object of the invention is to design an arcing chamber of the type defined in the introduction, while at the same time simplifying the overall structure, in such a way that the risk of incorrect switching, in particular due to the premature release of the latching between the extinguishing tube and the switching pin, is practically eliminated.
  • the latching device is arranged displaceably from at least one in a radial guide of the extinguishing tube Blocking member, a coupling groove provided on the switching pin and assigned to the blocking member and a control wall delimiting the radial movement of the blocking member consists of insulating material, and that the control wall at the point corresponding to the end of the predeterminable extinguishing pipe advance path has a cross-sectional expansion corresponding at least to the depth of engagement of the blocking member in the coupling groove .
  • balls as blocking elements, a pair of balls being expediently arranged in each radial guide of the extinguishing tube designed as a bore.
  • the side walls of the coupling groove and also the transition between the guide surfaces of the control wall, which are of different diameters, are preferably designed as inclined surfaces, whereby the problem-free and jerk-free actuation of the extinguishing chamber is promoted.
  • the thereby achieved high reliability even makes it possible to dispense with the usual inspection effort p oints in initial time.
  • a particularly advantageous embodiment of an extinguishing chamber of the eirgangs de, regardless of the special latching device Finished type consists in that the tubular housing consists of insulating material, that at least one current conducting path running along a housing surface line is provided on the inner wall of the housing, and that a burnout contact guided in an opening of the extinguishing tube is arranged between this current conducting path and the switching pin contact.
  • the use of a housing designed as a plastic tube is particularly advantageous because, compared to the conventional quenching chamber housings, the glow threshold voltage is higher and shorter distances to earth or to other live parts are possible.
  • the current path which can preferably consist of a spring or a wire, is simple and economical and fulfills the tasks assigned to it flawlessly, since it can handle high currents, e.g. Currents of around 600 A, only during milliseconds.
  • the burn-off contact is assigned a diametrically opposite pressure element which is under spring preload and is also guided in an opening of the extinguishing tube, this pressure element advantageously being cap-shaped and by means of a spring provided in the cap interior and one on the tubular housing supported ball can be biased radially inwards.
  • a longitudinal guide groove is preferably assigned to the ball belonging to the pressing element in the inner wall of the housing, thereby ensuring that rotation of the extinguishing tube is prevented.
  • the construction of the extinguishing tube according to the invention thus brings about an increase in functional reliability, a substantial saving in weight and, moreover, enables a significantly more economical production in comparison with previous extinguishing tubes.
  • the extinguishing tube comprises a tubular housing 1 made of plastic, an extinguishing tube 2 arranged within this housing and a switching pin 3 arranged in the extinguishing tube. Between the housing 1 and the extinguishing tube 2 there is a spring 4 and between the switching pin 3 and the extinguishing tube 2 a spring 5 arranged, and these springs 4, -5 bias the extinguishing tube and switching pin against the pull-out direction.
  • the switching pin 3 is provided in the usual manner at one end with a switching pin head 6 which interacts with the switching knives and at the other end with an erasing pin 7.
  • Extinguishing tube 2 and switching pin 3 are locked against each other, for which purpose the switching pin 3 has a coupling groove 8 in the area of its head-side end, in the blocking elements intervene in spherical shape.
  • These balls forming blocking elements are arranged in a radial guide 9 which is preferably designed as a bore.
  • two balls 10, 11 are each assigned to a radial guide 9, the outer ball 11 abutting a control wall 12 which is formed by a partially sleeve-shaped extension of the tubular housing 1 made of plastic.
  • This control wall 12 prevents radial expansion of the balls 10, 11 in the region of the predeterminable advance path of the extinguishing tube 2 and thus brings about a defined relative position of the extinguishing tube 2 and switching pin 3, i.e. a clear mutual locking.
  • a cross-sectional widening 13 is provided in the region of the free end of the part-sleeve-shaped control wall 12, and this cross-sectional widening enables the balls 10, 11 to move radially, with a jerk-free unlatching of the connection between the extinguishing tube 2 and the switching pin 3.
  • control wall 12 protrudes somewhat into the switching path, but this even has the advantage that an inserted separating plate can be brought into contact with this control wall 12, which consists of insulating material, and does not have to rest directly on parts carrying potential.
  • the current-carrying path running over the switching pin 3 comprises the contact ring 14 belonging to the switching pin 3, a burning contact 15 which bears against the contact ring and is guided in an opening 16 of the extinguishing tube 2, and a current conducting path 17 which runs essentially along a surface line of the tubular housing 2 and which leads to a connecting lug 18 leads to an extinguishing pipe mounting bracket 19.
  • the current path 17 can consist of a spring or a wire.
  • the contact pressure between the burn contact 15 and the contact. ring 14 is ensured by means of a pressing unit which is separate from the burn-off contact 15 and is essentially diametrically opposed, and which consists of a cap-shaped element 20 which is guided in an opening of the extinguishing tube 2 and in the interior of which a compression spring 21 is arranged, which is connected via a ball 22 the inner wall of the housing is supported.
  • Both the pressure element and the burn contact are designed so that they with their radially outer end areas are held on the extinguishing pipe wall and cannot fall inwards.
  • a metal mesh 23 made of stainless material is arranged, and this cooling grille is held within a cap 24 by means of a star-shaped cover element, the bent tabs of which prevent burned particles of the metal mesh from falling into the quenching chamber. An occurring fusion of these mesh particles with the tabs of the holder is not disturbing.
  • the mode of operation of the quenching chamber corresponds essentially to the mode of operation of the known quenching chambers of this type, that is to say that the switching pin 3 first takes along the quenching tube 2 via its advance path with compression of the spring 4, that the current runs over the flow guide described and at the end of the advance path the Latch between the extinguishing tube 2 and switching pin 3 is released.
  • the blocking balls 10, 11 are pushed radially outwards, the current conducting path in the extinguishing tube is separated while the extinguishing process begins at the same time.
  • the switching pin 2 is brought back via the spring 5 and the entire arrangement is returned to the initial position shown in the drawing with the locking of the extinguishing tube and switching pin.
