Definitions

  • the invention relates to a fuse bar or load bar for NH (low-voltage high-performance) fuses, also referred to as NH fuses inserts.
  • power converters can be used, which serve to measure the current in the fuse strip or load switch bar.
  • one or more current transformers use. The measurement of the phases can be done permanently without power interruption.
  • the current transformer (s) are installed inside the fuse or load breaker strip and wired to a transducer in the terminal compartment of the fuse or load-breaker strip and / or a multi-pole terminal or plug connector.
  • the strip is especially required in connection with NH fuses for fuse protection and switching of circuits.
  • the bar is further required, for example, to lead out the auxiliary circuits of an auxiliary switch for switching position displays, a transmitter in remote display, an electronic fuse monitoring.
  • Transducers are used to electronically capture electrical data of the fuse or enter detected electrical variables directly to the device. They are designed, for example, as measuring devices or evaluation electronics.
  • a fusebox or fuse switch for NH fuses comprising a housing, contacts arranged on a front side of the housing for receiving the fuses, wherein the contacts are connected to current conductors and the current conductors pass through recesses in the housing, and the respective arrangement of contact and current conductors in the housing is stored, wherein at least one arrangement of contact and conductor is associated with a current transformer, and the arrangement of contact and conductor passes through an opening of the current transformer, is from the AT 004111 U1 known.
  • a current conductor is approximately Z-shaped and has substantially mutually parallel end portions and a middle section connecting them. At least one of the two parallel sections is connected to the middle section, preferably detachably connected, in order to be able to plug the current transformer onto the power section in the region of the central section. For example, the middle section is bolted to one of the parallel sections.
  • the bar can in principle be retrofitted with the current transformer.
  • that of the power line serving conductor is to be separated here. Subsequent equipment of the bar with the current transformer is thus associated with a considerable effort, regardless of the high safety requirements to be complied with concerning the current-carrying components.
  • the NH fuse-link is a special component with shortened trained insulator, depart from which the two contact blades of the NH fuse-link, one of the contact blades longer than in a comparable NH fuse-link formed and therefore is suitable to receive a current transformer , This is thus not current-carrying components of the bar, but current-carrying components of the fuse link, specifically associated with the contact blade of the fuse link.
  • the object of the invention is to provide a fuse or switch-disconnector according to the AT 004111 U 1 so-called type so that they can be retrofitted without dismantling this bar as a whole or parts of the bar with one or more current transformers in a simple manner.
  • the object is achieved in that the arrangement of contact and conductor has a Aufsteck Scheme for front-mounting the current transformer on the arrangement of contact and conductor, wherein the cross section of the opening of the current transformer is greater than the cross section of the arrangement of contact and conductor in Aufsteck Scheme.
  • the bar can be easily provided with the current transformer not only in the initial installation, but it is also possible with mounted bar retrofitting this bar with the current transformer.
  • the arrangement of contact and conductor has the Aufsteck Scheme for front-side plugging the current transformer to the arrangement of contact and conductor. Since the cross section of the opening of the current transformer is larger than the cross section of the arrangement of contact and current transformer in Aufsteck Scheme, the current transformer can be easily pushed onto the arrangement of contact and conductor.
  • the indication of the cross section of the opening of the current transformer or the cross section of the arrangement of contact and conductor refers to a viewing direction in Aufsteckraum of the current transformer, whereby the cross-sectional area of the opening of the current transformer must be greater than the cross-sectional area of the envelope of the arrangement of contact and conductor in the Aufsteck Scheme and the cross-sectional dimensions in the two perpendicular to the direction of attachment extending spatial directions of the opening of the current transformer must be greater than the cross-sectional dimensions of said envelopes.
  • the plug-on region for the current transformer can, for example, only be in the region of the contact, or else only in the region of the current conductor. This allows a variety of designs of the bar and different arrangements of the or contacts with respect to the housing of the bar. If the current transformer is plugged only on the contact, the cross-sectional configuration of the contact according to the invention is taken into account and the cross-sectional configuration of the conductor arbitrarily, while plugging the current transformer via the contact on the conductor, the inventive cross-sectional configuration for contact and conductor, thus the arrangement of Contact and conductor, to be considered.
  • any number of contacts or any number of conductors can be equipped with current transformers.
  • the contacts are equipped with the current transformers.
  • the strip has three current phases and each of the three arrangements of contact and conductor is associated with a current transformer.
  • These three current transformers are used in particular for permanent current measurement and work together with an electricity meter. It is quite possible to assign a further current transformer to one phase, thus assigning two current transformers to the two arrangements of contact and conductor of this phase, the further current transformer serving, for example, as a display device in the context of a suburban measurement. Bars can therefore also have two or four current phases.
  • the conductor can be connected to a busbar.
  • the current transformer is associated with the conductor of the bar, through which the power of the bar is supplied.

  • the essentially U-shaped design of the contact makes it possible to place the current transformer on the contact due to the cross-section of the current transformer which does not change substantially, the legs passing through the opening in the current transformer.
  • the substantially parallel legs clamp an envelope which is rectangular so as to provide an opening in the current transformer that is rectangular, but slightly larger than the envelope provided by the two Leg of the contact is formed. If possible, the rectangular opening in the current transformer should be dimensioned so large that when, with the two legs of the contact, a spring is connected to allow in this case the plugging of the current transformer to the contact. Basically, this is not necessary because before attaching the transducer, the spring could be removed and connected again after attaching the transducer with the thighs.
