Definitions

  • An object of the present invention is the provision of an electrical switching apparatus which will avoid the drawbacks of prior art devices and satisfy the abovementioned requirements.
  • the present invention is concerned with an electrical high power switching device having compartments located one next to the other and a common channel for a trunk conduit located above or'below the compartments; side conduits extend from thechannel in a plane perpendicular to the longitudinal direction of the cornpartments and of the channeleither downwardly or upwardly, namely, toward the bottom or toward the upper wall of thecompartments, wherebyihigh power devices, such as load switches, are located in've'r'tical rows and are connected to the side conduits.
  • the objectsof the present invention are attained by providing novel component parts of an apparatus of this type and by arranging them in a manner'whichcombines exceptional operational safety with a clear and easily operable arrangement of devices belonging toone group.
  • the apparatus of thepresent invention is-essentially characterized by a construction wherein current transmitting conduits of the high power switchingdevicesare located in a chamber which contains only these conduits,
  • FIGURE 1 is a diagrammatic front view of a switching apparatus constructed inv accordance with the present invention, some parts being shown in. section.
  • FIGURE 2 is a horizontal section along the line 11-11 of FIG. 1 through the chamber for the trunk conduits.
  • FIGURE 3 is a horizontal, section along the line III-III of FIG. 1. i
  • the drawing illustrates a cross switching apparatus for high power energy distribution.
  • the apparatus comprises a number of compartments 10, 12, 14 etc. and a conduit chamber 16 common to all compartments.
  • the compartments of the apparatus include side walls 30, 32 and 30', a rear wall 38 and upper wall 16'. These walls consist of an insulating material having an exceptionally high dielectric disruptive strength, such as a spe cific composition of wood fibers enclosed in gypsum plates and cured in a plastic material, the composition being known in the trade under the trademark Gibogi.
  • Side conduits 24, 26, 28 and 24', 26', 28 have the shape of double rails and extend close to the walls 30 and 30', respectively. As will be explained in detail hereinafter, it is of utmost importance that these walls be made of said insulating material.
  • the side conduits 24, 26, 28 are connected at their upper end to the trunk conduits 18, 20, 22, respectively, and extend downwardly through the compartment 10,
  • conduits 24, 26', 28' are similarly arranged in the adjacent compartment 14.
  • Each of the distributing units 52 includes three fuses 40, three high power switches 42 and three connecting conduits 44.
  • the connecting conduits 44 extend through the wall 32 of the compartment 10 and are connected to distributing cables 46.
  • the outer end of the movable switch arm cooperates with one of' thetwo terminals of the fuse 40, while the other terminal of the fuse engages an immovable contact i 25 connected to one of the side conduits 24, 26, 28.
  • the compartment 10 contains a large number of these distributing units 52 which have the shapeof frames and are mounted one over the other, each in its own story or vertical section, and which can be easily individually removed and replaced.
  • each distributing 'unit 52 consist of commercially available normalized fuses of the melting wire type for a maximum current of 600 amp.; the three fuses of each unit 52 are located in a slider (not shown) by means of which all three fuses can be simultaneously inserted into a distributingunit 52, or removed therefrom.
  • the switches 42 maybe actuatedremotely by compressed air from containers 50 located in the compartment 12 andconnected with the switches by driving means 48 consisting of mechanical coupling elements wardly to the chamber 16; for reasons of safety the wall '36 consists, in the usual manner, of steel sheets. With the exception of members interconnecting the compartment walls, this wall is the only large component part of the compartments which consists of magnetizable material.
  • the wall 36 should be arranged at a distance and as far as possible from the electric current paths.
  • this speed can reach up to 4000 m./s. inthe case of a short circuit current of 100 ka. and a distance of a few millimeters between the circuits.
  • An electric high power switching device comprising, in combination, at least one trunk conduit, means forming a horizontal chamber enclosing said trunk conduit, a plurality of side conduits connected with said trunk conduit and extending substantially perpendicularly and down wardly thereto, at least three spaced side Walls in parallel to each other and consisting of an insulating material with high dielectric disruptive strength extending close and parallel to said side conduits, said walls forming at least two compartments receiving said side conduits and extending substantially perpendicularly to said chamber, and a plurality of distributing units located one over the other in one of said compartments, each of said distributing units comprising at least one switch secured to the middle one of said three walls and a melting wire fuse cooperating with said switch and connecting said switch with one of said side conduits, said fuse together with said switch providing a horizontal path for an electrical current between said one side conduit, said fuse, said switch and a distributing cable, the interior of said compartment being substantially free of magnetic material.
  • a device in accordance with claim 1 comprising a fixed contact connected to said one side conduit and receiving one terminal of said melting wire fuse, the other terminal of said fuse being adapted to be engaged by said switch when the switch is closed.
  • a device in accordance with claim 1 further comprising a rear wall enclosing said compartment and consisting of the same material as said side walls.
  • each switch comprises a swingable arm and a pivot carrying ,ments consisting of a non-magnetic material.
