Definitions

  • the invention relates to an arrangement of a carrier part and at least one cover of a safety edge, in particular a power switch, preferably a fuse switch.
  • a safety edge is, in particular, a low-voltage, high-performance (NH) load-sensitive edge.
  • Switching strips of the type mentioned at the beginning typically have contact elements connected to current leads and current outlets, an electrical fuse or a disconnecting knife being insertable into the contact elements in order to form an electrical connection between the contact elements.
  • such switching strips have a lower part with connections for busbars and / or cables, a support part which can be connected to the lower part and a cover mounted in the support part, the cover having at least one receptacle for storing an electrical fuse and / or a disconnecting knife.
  • the cover usually has a cover part and a shift lever pivotally mounted in the cover part, for the purpose of transferring the cover part from a first end position into a second end position and vice versa.
  • Such switching strips are for example from the EP 1 993 116 A1 as well as the DE 381 25 04 A1 known.
  • Safety edges are usually equipped with electrical fuses. However, devices are also used, especially for infeed systems, which are not equipped with electrical fuses but with cut-off knives. This also takes into account the low power loss and short-circuit protection on the primary side of the supply transformer. Dynamic switching current resistance, namely the safety edge, is often expected here. This means that in the event of a short circuit, the safety edge deliberately does not respond.
  • the load on the load switching strip results here on the one hand from the current peak when the power is switched on and on the other hand from the load in the event of a short circuit (usually 1 second).
  • a short circuit usually 1 second.
  • the dynamic load during the electrical switch-on process of an upstream structure often leads to the fact that the separating knives and / or the electrical fuses are thrown out of the contacts of the safety edge by the current dynamic repulsive forces. This creates a risk to people and facilities.
  • Locking devices can prevent the cutting knife or the electrical fuse from being thrown out.
  • a mechanical blocking device for cutting knives is known.
  • the separating knife is inserted into a contact arrangement, the blocking device preventing the separating knife from being thrown out of the contact arrangement in the event of a short circuit.
  • the blocking device has an element for transmitting a blocking force in the event of a short circuit the contact arrangement on the cutting knife.
  • a single-pole or multi-pole NH switching strip which comprises a lower part with current-carrying parts for receiving fuse links, an upper part with a switching cover pivotally mounted therein by means of a pivot bearing, which together cover the current-carrying parts in a contact-safe manner.
  • On the underside of the switch cover there is a separating knife which is firmly connected to the switch cover and which can be inserted into or removed from the lower part instead of a fuse link using the switch cover.
  • the NH switch strip On the side of the switch cover opposite the pivot bearing, the NH switch strip has a locking device with which the switch cover can be secured in the closed position against unintentional pivoting out. To improve the dynamic strength, the locking device is designed as a detachable connection between the switch cover or the separating knife firmly connected to it and the lower part or the current-carrying parts arranged in the lower part.
  • the cover has a cover part and a shift lever, the cover part being movably mounted in the carrier part for transferring the cover part from a first end position to a second end position and vice versa.
  • the cover In the first end position of the cover part, the cover is in a closed position, in the closed position a separating knife arranged in the cover part or an electrical fuse arranged in the cover part contacts contacts of a lower part which can be connected to the carrier part, the contacts having a power supply and a power outlet are connected.
  • the shift lever is pivotally mounted in the cover part about a pivot axis, for transferring the shift lever from a first pivot position into a second pivot position and vice versa, the shift lever cooperating with the carrier part for transferring a pivoting movement of the Shift lever in a movement of the cover part relative to the carrier part.
  • the cover part is arranged in the first pivot position of the shift lever in the first end position.
  • the object of the present invention is to develop an arrangement of a carrier part and at least one cover of a safety edge, which has the features of the preamble of claim 1, in such a way that this arrangement reliably prevents the separating knife from being thrown out in the event of a short circuit.
  • this arrangement reliably prevents the separating knife from being thrown out in the event of a short circuit.
  • damage to the carrier part and / or the cover and / or a switching strip having the arrangement occurs.
  • the arrangement according to the invention in particular advantageous developments of the arrangement, should make it possible to easily retrofit existing safety edges in order to protect them against damage, in particular when using separating knives, in the event of a short-circuit current, or to endanger the environment of the safety edge in the event of a short-circuit current to prevent.
  • the cover has a mechanical locking device, the locking device having locking means that can be moved between an open position and a locking position and vice versa.
  • the locking means bring about a form fit between the shift lever and the carrier part or between the shift lever and the cover part, in order to prevent the shift lever from pivoting from the first pivot position into the second pivot position.
  • the locking means bring about a form fit between the cover part and the carrier part, in order to prevent the cover part from moving from the first end position into the second end position.
  • the mechanical locking device effectively causes a double locking of the cover in the event of a force acting on the cover, for example as a result of a short-circuit current.
  • the lid is particularly well secured in the carrier part. The locking is achieved by an interaction between the cover, the carrier part and the locking device, so that no direct interaction of the locking means with other elements of a switching strip, such as the lower part or components of the lower part, is necessary.
  • the locking means In the locking position, the locking means preferably bring about a positive connection between the shift lever and a side wall of the carrier part and / or between the cover part and the side wall of the carrier part.
  • the carrier part can be connected to a lower part of the switching strip, the lower part having contacts connected to a power supply and a current outlet, this electrical fuse being used for a lower part connected to the carrier part and an electrical fuse arranged in the cover part or a separating knife arranged in the cover part or the separating knife contacts the contacts of the lower part in the first end position of the cover part.
  • the carrier part preferably has fastening means on a base facing the lower part in order to fasten the carrier part on the lower part.

  • the locking device prevents inadvertent switching of the safety edge in the locking position.
  • the locking device is preferably formed by a separate component which is connected to the cover part and / or the shift lever.
  • This design of the locking device enables a particularly simple assembly of the locking device, in particular a production of the locking device independent of the manufacture of the cover part and the shift lever, on the other hand, this design enables an optional equipment of a cover with the mechanical locking device and also a particularly simple equipment or Retrofitting existing covers.

  • one and the same locking element effects both a form fit between the shift lever and the carrier part or between the shift lever and the cover part and a form fit between the cover part and the carrier part.
  • particularly few components are required, since one and the same component, namely the locking element, takes on two different tasks, namely the locking of the cover part and the locking of the gear lever.
  • the forces acting on the at least one locking element which act on the locking element due to the shift lever and on the locking element due to the cover part, do not act on the locking element in the same but in different directions. This reduces the mechanical load on the locking element in the form of the resulting force, in particular a shear force that arises due to the positive locking, and prevents damage to the locking element or even destruction of the locking element, since the resulting force is less than the sum of the amounts of the acting forces.
