Definitions

  • the invention relates to a high-voltage circuit breaker with a main switching point and with a resistor arranged within an elongated insulating housing and an auxiliary switching point arranged approximately in the center of the insulating housing, which has a spring mechanism that can be tensioned by the drive of the main switching point and acts in the opening direction and a device for position-dependent unlatching having.
  • a high-voltage circuit breaker of this type is known from DE-PS 21 08 915.
  • a resistance column is arranged on one side of the auxiliary switching point, while on the other side of the auxiliary switching point, a spring accumulator and a movable contact piece are guided within a cylinder.
  • the invention is based on the object of realizing different resistance values and in particular also higher resistance values than previously with unchanged external dimensions of the insulating housing.
  • this object is achieved in a high-voltage circuit breaker of the type mentioned at the outset in that the resistor consists of two resistance columns located on both sides of the auxiliary switching point and in that the spring accumulator of the auxiliary switching point is assigned to the insulating housing on the end face.
  • the spring accumulator is no longer inside the insulating housing, there is practically no change in the longitudinal dimensions because the spring accumulator can be made a component of subsequent assemblies of the circuit breaker.
  • An advantageous arrangement consists, for. B. in that the insulating housing of the resistor is attached with its one end face to a gear housing in which the spring accumulator of the auxiliary switching point is located.
  • Each of the resistance columns can be held together by individual insulating tubes which pass through stacked resistance bodies and can be braced with respect to the end plates of the insulating housing.
  • a largely constant pressure force of the resistance columns can be ensured here that a head piece is connected to the insulating tube at the inner end of each resistance column and that compression springs are arranged between a pressure piece closing the resistance column and the head piece.
  • the auxiliary switching point can comprise a spring-loaded pressure contact piece arranged at the inner end of one of the resistance columns and a switching piece which cooperates with it and can be moved by an insulating actuating rod.
  • This arrangement can be made insensitive to changes in the relative position of the opposing ends of the two resistance columns, as z. B. can be caused by heating.
  • the pressure contact piece can consist of a graphite plate and a carrier guided against spring force within a housing fastened to the head piece. Graphite has no tendency to stick or weld and is therefore particularly suitable for pressure contacts. Safe contact can also be promoted by friction damping and / or gas damping, against which the pressure contact piece can be moved in its housing.
  • the associated head can contain a resistance column a sliding contact arrangement and can also form a shielding electrode for the switching element in the off position. This eliminates the need for a shielding electrode as an independent component.
  • Fig. 1 shows a resistor in a longitudinal section.
  • a resistor is shown in a reduced representation corresponding to FIG. 1 with a part of a gear housing and a main switching point.
  • the resistor 1 in FIG. 1 which can be used as a damping resistor in the same way for switching on or off, has an elongated insulating housing 2 which consists of porcelain and is provided with ribs. Fittings 3 and 4 are cemented onto the shieldless ends of the insulating housing 2, which have threaded holes for fastening a cover 5 or 6 by means of screws 7. In the area of the end cover 6, screws are not shown in FIG. 1, because these are only inserted after a resistor 1 has been attached to a gearbox of a circuit breaker, as will be explained with reference to FIG. 2.
  • the resistance column 10 consists of a number of mutually identical resistance disks 12, which have a centrally arranged through opening 13 through which an insulating tube 14 or 19 extends. At its outer end, ie the end plate 5 facing, this is an insulating tube 14 in one Fixed base body 15 which is screwed to the end plate 5 from the inside. At its inner end, that is to say the end facing the entire auxiliary switching path 16, the insulating tube 14 is anchored in a head piece 17, which at the same time serves as a carrier for the fixed part of the auxiliary switching path 16.
  • a plurality of compression springs 21 are arranged between the head piece 17 and a pressure plate 18, which closes the resistance column 10 together with intermediate layers 20, a plurality of compression springs 21 are arranged. These exert a pressing force on the resistance body 12 which, with suitable dimensioning of the springs 21, is largely independent of the temperatures which can occur during operation of the circuit breaker and its damping resistor 1. This ensures a perfect power transfer between all parts.
  • FIG. 1 Separated by the dash-dotted center line 22, different embodiments are shown in FIG. 1 insofar as a solid filler piece 23 is provided in the lower part between the base body 15 and the resistance bodies 12 and a hollow cylindrical filler piece 24 is provided in the upper part. Both metal fillers 23 and 24 are used to maintain the position of the head piece 17 in the insulating housing 2 despite different resistance values of the resistance column 10.
  • the head piece 17 of the resistance column 10 serves as a carrier of the fixed part of the auxiliary switching path 16.
  • This consists of a housing 25 in which a support plate 26 with a graphite plate 27 fastened thereon is displaceably guided against the force of a compression spring 30.
  • the housing 25 has at its base an opening 28, the size of which is such that gas flows out of the housing at the Movement of the support plate 26 is hindered and thus gas damping occurs when a contact piece 35 to be described hits the graphite plate 27.
  • a friction body 29 is effective between the housing and the support plate 26. This combined gas and friction damping prevents bouncing when the auxiliary switching path 16 closes.
  • the further resistance column 11 arranged in the insulating housing 2 also consists, in the manner already described, of individual resistance bodies 12 provided with through-openings 13.
  • a further insulating tube 19 extends through the openings in the manner already described, which is connected to its outer, ie the end plate 6 facing end in this and at its inner, ie the auxiliary switching path 16 facing end in a further head piece 31 is attached.
  • Compression springs 32 which are arranged between the head piece 31 and a further pressure plate 33, transmit a pressure force to the resistance body 12.
  • an actuating rod 34 made of an insulating material, on the inner end of which, ie facing the auxiliary switching point 16, a contact piece 35 is fastened with a contact cap 36.
  • the switching piece 35 with its tip 36 is surrounded by a tubular extension 37 of the head piece 31, as a result of which a shield is formed.
  • the contact piece 35 cooperates with its contact tip 36 and the graphite plate 27 in the manner of a pressure contact.
  • the quality of the contact is largely independent of tolerances both in FIG guaranteed axial and radial direction.
  • the diameter of the graphite plate 27 is deliberately dimensioned much larger than the diameter of the end face of the contact tip 36.
  • Fig. 2 shows the attachment of the resistor 1 to a circuit breaker.
  • the same reference numerals are used in FIG. 2 for the main components of the resistor 1.
  • the insulating housing 2 of the resistor 1 is attached with its end plate 6 to a gear housing 40, by screws 41, which extend through through openings of the end plate 6 into threaded holes in the flange 4.
  • Part of the gear housing 40 is a cylindrical part 42 which receives a compression spring 43 and a piston-like guide piece 44.
  • the actuating rod 34 of the auxiliary switching point 16 is connected, while on the opposite side a coupling rod 45 engages by means of a ball joint, which is part of a crank mechanism designated as a whole by 46.
  • resistor 1 is used as a switch-on resistor, the following switching operations take place: starting from the switch-off position, in which both the main switching path within the insulating housing 47 and the auxiliary switching point 16 of resistor 1 are open, the auxiliary switching point is first closed while the Main switchboard is still open. Both switching points are temporarily closed, so that the resistance columns 10 and 11 are bridged by the main switching point.
  • the coupling rod 45 is then released by a known device for position-dependent release, as described for example in the aforementioned DE-PS 21 08 915 and which is part of the crank mechanism 46, so that the actuating rod 34 under the influence of the previously tensioned spring 43 is moved to the off position shown in the figures.
  • the insulating housing 2 of the resistor 1 is a porcelain tube provided with ribs.
  • the resistor is particularly suitable for use on outdoor switches.
  • the resistance is also suitable for installation in metal-enclosed switchgear, with the design unchanged in principle. For this purpose, the replacement of the insulating housing 2 with a smooth plastic tube of the same dimensions is recommended.
