Definitions

  • the invention relates to a cover made of insulating material For fuse contacts arranged in pairs on NH (low-voltage, high-performance) fuse strips or parts, wherein the cover two hood-shaped cover elements for the Fuse contacts and one arranged between the covers Has base plate.
  • Covers serve the contacts and especially on electrical ones Power distribution networks people working in front of the to protect against accidental contact with the contacts.
  • the contacts of such a fuse strip exist each consisting of a pair of resilient elements, between which the Contact knife of a fuse link inserted under pressure can be.
  • the two contact parts are one Contact integrally connected to each other on her lower foot. From the base of these contacts there is a connector for connection with a busbar.
  • Generally are on one Fuse strip for the three phases of the three-phase network three pairs of contacts arranged in a row, one contact of the three contact pairs with one Outgoing conductor is connected while the other three contacts are connected to a busbar and in general to be under tension. Between such a pair of contacts each arranged a fuse link, which with its Contact knife is inserted between the contact surfaces and can also be pulled out of these.
  • a cover of the type mentioned is from DE-OS 39 18 816 known. This is formed in two parts, one Hood and essentially part of a half of the base plate represents and the other part through the other hood and in the essential other half of the base plate is formed. At the Undersides of the base plate are provided in the area which the respective base plate part in the housing of the fuse block is clickable.
  • the one base plate part is in Area of its end face facing the other base plate part with a substantially semicircular shape Provide projection and it has the other base part appropriately designed recess through which the projection passes. When the base plate part having the projection is removed becomes the assembly connection under the recess for the busbar contact belonging to this fuse link accessible.
  • This connection essentially exists from one with the corresponding busbar contact connected discharge angle, for example as an L-shaped Rail with an elongated hole in the angled L-leg is formed through which a screw bolt are passed can, so that the L-leg to the associated busbar can be screwed on.
  • a disadvantage of the known cover that when working on Bolt, for example to tighten this, a part the cover, namely the base plate part having the projection must be removed with the associated hood, with which the contact usually covered by the hood, the can be due to tension, is freely accessible. The one in The area of the security personnel is subject to one increased risk.
  • Another disadvantage is that the cover consists of two parts and therefore during assembly or Disassembly of the cover always handled two components separately Need to become. The result is that a part remains loose and this cannot rule out that part is lost or is not assembled.
  • the task is solved by covering the entrance mentioned type in that the base plate with a closable Opening is provided.
  • the design of the cover according to the invention ensures that this always covers the pair of fuse contacts, regardless of whether work is carried out in the area of the bolt have to. So that the bolt is accessible, it is only required to make the opening accessible. In the between The two opening hoods formed can then the screw bolt can be applied unhindered. Are the Assembly work finished, it is only necessary to open the opening to close the base plate. The two fuse contacts and the area between them are then safe to touch covered.
  • the cover is as Plastic injection molded part.
  • the cover is in one piece is trained. As a result, it can be handled as a unit are what their assembly and disassembly much easier. All functional elements of the cover are in one component housed, making their handling particularly easy.
  • the base plate is preferably a flap for closing assigned to the opening.
  • the one-piece cover thus also extends to the flap with it not as a separate and loosely connected to the base plate
  • Removable component is formed from the base plate. Forms the flap part of the cover it is considered appropriate viewed when in kind of a film hinge with the base plate connected is. Without the functionality of the flap too can affect this due to the design of the hinge enough times to open or close the opening in the base plate can be pivoted.
  • locking means for locking Flap and base plate with the base plate opening closed are provided.
  • the flap is useful on its side facing away from the flap bearing lockable with the base plate.
  • Locking means provided, for locking the flap and base plate in the open position of the flap.
  • the flap in the Area of the flap bearing with the base plate or at least an approach connected to the base plate can be locked.
  • the respective hood is expediently designed like a cage. she points at least in its area facing the base plate Ventilation slots for removing the fuse during operation resulting heat loss.
  • the respective hood is expedient on the other hood facing side and its side facing away from the base plate with an angle slot for inserting the contact knife fuse insert to be inserted into the fuse strip or lower part provided, the slot in its the Slit area facing away from the base plate has a smaller width has than the thickness of the contact knife.
  • a dimensioning aid is used for positioning Switch on, which allows the operator with a defined force the respective contact blade of the NH fuse link with respect the cover and thus that behind the respective hood Align fuse contact. During the switching process the hood in this slot area widened and the switching knife guided past the position aid.
  • the cover with the fuse contacts connected is clipped onto this.
  • the cover resilient projections be, for clipping the cover on the associated Safety contact, the corresponding recesses for engagement which has protrusions.
  • a further training provides that at least one of the hoods an opening for inserting a contact element has separate current outlet, the contact element of the separate current outlet on a contact knife one in the Fuse contacts of inserted NH fuse link can be plugged on is.
  • a cover element is preferably in the hood for the contact element of the separate pluggable into the hood Integrated power outlet.
  • Such a separate power outlet the is also known in practice as a piggyback tap usually the purpose of a temporary power tap enable, for example to operate construction sites, notch or Fair events, etc. Is the current tapped from the feed-in side, this is additionally secured.
  • the projections are preferred at least in this hood on her facing the other hood Side integrated at least two resilient projections, wherein between the free end of the resilient projections and the Cover surface of the hood a gap for inserting the contact element the current outlet is formed. If the contact element of the Current outlet from the contact knife of the NH fuse link separated, the projections spring back and the. is reduced Width of the gap so that the hood is finger-safe in this area is. By means of the resilient projections, the rest of the Contact element of the current outlet clamped. In addition can at least one of the projections should be designed so that it used separate power outlet with its contact element rested. There is thus an unintentional loosening of the separate one Current outlet, for example due to the contact element initiated vibrations, effectively prevented.
  • the power plate on both sides between the two covers with removable cover flaps is provided.
  • These can be found for the special area of application the sliding separation of a rail system use.
  • adjacent covers in Busbars ending at a distance from one another by means of a Slidable in the longitudinal direction of the respective cover plate Connecting element electrically connectable. This connector becomes accessible if the cover flaps are adjacent Covers broken out of the cover plate or when in Kind of a film hinge are formed from the level of Cover plate can be swung out, so that there the area underneath the two covers for connecting or disconnecting the both busbars is accessible.
  • Figure 7 illustrates that the cover 1 of the invention is designed as a one-piece injection molded part made of plastic, a base plate 2 and two themselves in the area of their ends this has extending hoods 3.
  • the hoods 3 are in the Area of the base plate arranged perpendicular to this Provide ventilation slots 4.
  • the respective hood 3 has their side facing the other hood 3 and on their Base plate 2 facing away from an angle slot 5 through each a contact knife 6 of a NH fuse link 7 can be inserted into the hood 3.
  • the cover 1 serves covering two fuse contacts, not shown, by means of the hoods 3 and the one below the cover 1 Area of an NH fuse block or an NH lower part.
