Definitions

  • Connection rail for electrical devices and apparatus, for different nominal currents, with a cavity
  • the invention relates to connecting rails made from profiled semi-finished products and provided with a cavity for connecting the electrical components of electrical devices and apparatus to an external circuit, the connecting rails extending through window openings in the device or device wall and fixed in the housing by means of fastening means are.
  • Connection rails of this type have been proposed in DE patent application 199 39 710.4.
  • a system-side supply rail or another suitable connecting element for energy supply or dissipation can be connected to the part of a connecting rail which is led out of the housing.
  • the connecting rail is generally fixed in the insulating wall body of a device or apparatus, which is usually realized with the aid of lead-through openings and fastening elements.
  • connection rails must continue to be designed in such a way that they can be produced efficiently and are suitable for performing certain functions. These functions are: current carrying capacity, heat dissipation, an area for connecting supply rails and the absorption and transmission of static and dynamic forces. So it is a strong and dynamic place.
  • connection rails for different currents in a uniform housing with uniform through openings.
  • screws which extend through openings arranged transversely to the longitudinal axis of the connecting rails and for the reception of which a nut thread is generally provided in the wall of the corresponding housing.
  • metallic insert nuts or press-in nuts are used for this in a housing consisting of an insulating material.
  • connecting rails which are sawn off from a profile material with one or more protrusions, in such a way that the connecting rails are inserted through a hole and the protrusion or protrusions of the profile material serve as stops of the connecting rail on the switch housing and thus form the force transfer of the switching forces to the housing.
  • connection rail for a low-voltage circuit breaker, with a molded projection
  • This connecting bar is inserted from inside through the through opening of the housing wall and is supported 'by means of a projection on the housing rear wall.
  • special profiles are used which have a one-piece molded strip, from which pieces are then cut off, which form the connecting rail.
  • connection rails With low-voltage circuit breakers, it has so far been customary within a series to use connection rails of different thicknesses depending on the nominal current.
  • connection rails are also made from profiles by sawing.
  • the housing has uniform cutouts for the connection rails, which are each designed for the largest nominal current.
  • Spacers made of plastic are used for thinner connecting rails with smaller nominal current strengths, which fill the gaps.
  • the assembly of the spacers has the disadvantage of additional costs for these parts as well as higher assembly costs and they form a source of error when the current paths are installed by the customer.
  • the connecting rails are made of solid material, regardless of the other manufacturing technology. This means that the rails also have different cross sections for different current strengths and thus different external dimensions; a disadvantage that has already been dealt with above.
  • Hollow current-carrying conductors are known from high-voltage and high-frequency technology. With these waveguides, the hollow design serves only the purpose of reducing the corona losses of the conductors, i.e. the radiation of energy at sharp edges or narrow radii, or to take into account the skin effect, which is based on the fact that at high frequencies only in the outer area of a conductor Energy is transmitted, but not the purpose of a different current-carrying capacity with a uniform exterior
  • a current-carrying hollow arrangement is also described in US Pat. No. 3,597,713, which shows a device as a replacement for a high-voltage fuse, in which a combination of a vacuum switch and a switching handle, which, similar to a high or medium-voltage isolating switch, has an eyelet for actuation, is shown.
  • An electronic circuit is built into a hollow connector of the device.
  • hollow connecting rails for low-voltage circuit breakers, which are made from a hollow profile material by sawing and can have only one or more cavities.
  • These connection rails have the same outer cross-section for all different current strengths.
  • the current carrying capacity is regulated by means of the wall thickness of the hollow rail, which forms the conductive, current carrying cross section. This means that there is a larger inner cavity at lower currents due to small wall thicknesses, and a smaller inner cavity at higher current intensities due to thicker wall thicknesses, which can lead to a massive design without a cavity at the highest rated current.
  • the feedthrough openings in the respective device and apparatus housings are then designed for the external dimensions required for this highest rated current.
  • the production of such hollow profiles from some materials that are preferably used for the production of such connecting rails is associated with considerable difficulties.
  • the object of the present invention is therefore to design hollow connecting rails so that they have the same outer cross section even at different nominal current values and without additional spacers in device and apparatus housings with uniform through openings. gene can be used, but avoid the problems in the production of hollow semi-finished profiles.
  • the hollowness of the connecting rail is caused by the fact that it consists of two or more sections which are designed as profiles and are designed in such a way that they can be positively or otherwise connected to one another to form a hollow connecting rail.
  • Such partial profiles can be easily and without the in the manufacture of
  • the connecting rail is preferably composed of two profile-shaped sections, of which the first section forms the upper part of the connecting rail and the second section the lower part thereof. This results in flat upper and lower rail surfaces, which is particularly important with regard to use for slide-in switches in order to achieve perfect sliding into the slide-in blade contacts.
  • the sections have one or more legs, the lengths of which determine the height of the connecting rail. This ensures that the connection rails have the same external dimensions for all currents, which correspond to the uniform dimensions of the lead-through windows in the rear wall of the low-voltage circuit breaker.
  • the current carrying capacity of the connection rail is determined by the thickness of the material.
  • One or more legs of the one in each case are expedient
  • the three legs are advantageously provided, two of which are arranged on one section and one on the other section. This results in a simpler manufacture for the sections than if all the legs were arranged on one section.
  • the sections are by one or more positive connections and / or partially connected by soldering, welding or the like. Required holes for fastening the system-side busbars are advantageously punched.
  • FIG. 1 schematically shows a low-voltage circuit breaker in section.
  • FIG. 2 shows a possible advantageous embodiment of a lower connecting bar according to the present invention in section.
  • FIG. 3 shows the connection rail according to FIG. 2 in the state before the parts are joined together in a perspective view.
  • FIG. 4 shows the connecting rail of FIG. 2 after the parts have been joined together in a perspective view.
  • a low-voltage power switch 1 is shown schematically in section.
  • the upper connecting bar 3 shown in conventional form, and the lower connecting bar 4, shown in the embodiment according to the invention and led through the current transformer 6, are led out.
  • the fixed switching contact 5 is located on the upper connecting rail 3 and the movable switching contact 10 located on a contact carrier 9 connected to the switch drive 8 is connected to the lower connecting rail 4 via flexible connections (not shown).
