Definitions

  • the invention relates to a rear connection system for low-voltage circuit breakers.
  • Circuit breakers for large rated currents are usually opened from the rear main power lines connected to the infeed and load side.
  • the main power lines are generally designed as solid connection rails.
  • the circuit breaker is either mounted directly on horizontal supports or frequently connected to an extension unit for its assembly and disassembly during maintenance, Facilitate inspection and repair.
  • the mounting level of the circuit breaker runs parallel to its front.
  • the flat rectangular main power lines to be connected either run vertically to the mounting level of the circuit breaker, with it upright or transverse are arranged, or they run from top to bottom or vice versa or from left to right or vice versa, either with their broad or with their narrow sides run parallel to the assembly level.
  • the invention is therefore based on the object of a versatile connection system specify.
  • the feed-side and the load-side main power lines are each with one Ball joint located on the rear of the circuit breaker connect.
  • the ball joints each contain a pan and a bowl, which contact a spherical end of the connector.
  • the Connector can be assembled before assembling the ball joint Longitudinal axis in different positions and before tightening the ball joint be pivoted into the desired position in a simple manner, i.e. without Adaptation via a special intermediate piece, with the generally rail-shaped Main power line to be connected.
  • the shell is advantageously finger-like with meridional openings executed, in particular with openings of equal width, through which this on Place cross-sectionally formed connector is sufficient.
  • the connector In order to can the connector before assembling the ball joint as well with respect to its longitudinal axis by 90 ° and before tightening the ball joint with respect to the vertical as well as the horizontal within an angular range of 180 ° offset.
  • An inserted spring means is advantageous for tensioning the ball joint. It is advisable to screw the shell to the connecting rail.
  • the Use of liquid metal between pan and ball on the one hand and / or Shell and ball on the other hand is advantageous for creating a low contact resistance in the ball joint.
  • connection system the circuit breaker can depend on Requirement or given with from behind, from above or below or from the left or connecting rails approaching on the right and running across or upright can be connected without the need for different accessories. Also So far not common connection directions are with the connection system according to the invention realizable.
  • FIG. 1a to 1d show exemplary possibilities according to the prior art, differently tapering and aligned rail-shaped main power lines 3a, 3b, 3c or 3d to be connected to a circuit breaker 2 on the rear.
  • the main power lines 3a step vertically through the assembly level 6 of the circuit breaker 2 and are arranged transversely (Fig. 1a).
  • the main power lines 3b occur also vertically through the assembly level 6, but they are arranged upright (Fig. 1b).
  • the main power lines 3c run from top to bottom or from below upwards and are arranged parallel to the assembly level 6 (Fig. 1c).
  • the main power lines 3d again step vertically through the assembly level 6, are transverse arranged, but angled on the connection side (Fig. 1d).
  • connection system has for everyone to be connected to the feed-side or load-side main current conductor 4 at the rear ball joint 1 attached to the circuit breaker 2.
  • Fig. 2 represents the sectional view II-II according to FIG. 3c.
  • the ball joint 1 consists of a directly with the Circuit breaker 2 connected pan 10 made of copper.
  • the pan 10 has one spherical-carrot-shaped concave inner surface 11.
  • the ball joint 1 continues to exist from a mechanically stable copper that can be detachably connected to the pan 10 Shell 12.
  • Shell 12 has two vertically intersecting, meridional extending, equally wide openings 13 and one interrupted by the openings 13 spherical cap-like inner surface 14.
  • the shell 12 has one flange-like edge region with holes 15, through which they are screwed 21 are attached to the pan 10 to form a spherical cavity can.
  • the ball joint 1 finally consists of a copper connector 16, on the one hand to a ball 17 and on the other hand to a connection end 18 is formed with connection bores with which the connecting piece 16 to be electrically conductively connected to the main current conductor 4 by means of second screws 22 is.
  • the edge length is advantageous the cross-sectional area of the middle part 19 is significantly smaller than the diameter the ball 17 and the wide cross-sectional edge of the connection end 18, but the same the narrow cross-sectional edge of the connection end 18 and slightly smaller than the width of the openings 13. Furthermore, before the shell 12 is put on the connector 16 on the pan 10 a flat, highly conductive spring means 20 inserted into the inner surface 11 of the pan. Before the final bracing of pan 10, shell 12, ball 17 and spring means 20 by means of the first screws 21, the connection end 18 is aligned in the desired direction.
  • a low contact resistance between the contacting surfaces of the ball joint 1 can advantageously also be achieved in that within the ball joint 1, a layer of liquid metal, for example, from a Alloy of 660 parts by weight gallium, 205 parts by weight indium and 135 Parts by weight of tin is inserted.
  • FIG. 4a to 4f is schematic with a view towards the rear of the circuit breaker shown how different with the connection system according to the invention incoming and aligned main power lines 4a to 4f are connected can by connecting to the connector end 18 of the connector 16 of the Ball joint 1 are connected.
  • the main power lines 4a, 4b, 4c and 4d run parallel to the assembly level from below (Fig. 4a), from above (Fig. 4b), from the left (Fig. 4c) or from the right (Fig. 4d) towards the circuit breaker and are lying flat parallel arranged to the assembly level.
  • the assembly plane runs parallel in FIGS. 4a to 4f to the drawing level.
  • the main power lines 4e and 4f run perpendicular to the mounting plane and are arranged transversely (Fig.
  • connection is more or less arbitrary Connection rails possible.
  • those in Fig. 4e and 4f shown variants can easily be converted into other variants by the connecting piece 16 starting from Fig. 4e by 90 ° to the left or right or is pivoted upwards or downwards from FIG. 4f by 90 °.
