Definitions

  • the invention relates to an arrangement of a carrier part and at least one cover of a switching strip, in particular a load switching strip, preferably a fuse switching strip.
  • the safety edge is in particular a low-voltage, high-performance (NH) load safety edge.
  • Switching strips of the type mentioned at the outset typically have contact elements connected to power supply lines and power outlets, it being possible for an electrical fuse or a disconnect blade to be inserted 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 carrier part that can be connected to the lower part, and a cover mounted in the carrier part, with the cover having at least one receptacle for mounting an electrical fuse and/or an isolating blade.
  • the cover usually has a cover part and a switching lever pivotably mounted in the cover part for the purpose of transferring the cover part from a first end position to a second end position and vice versa.
  • Such switching strips are, for example, from EP 1 993 116 A1 as well as the DE 381 25 04 A1 famous.
  • Switch strips are usually equipped with electrical fuses. However, devices that are not equipped with electrical fuses but with isolating blades are also used, especially for feed-in systems. This also takes into account the low power loss and short-circuit protection on the primary side of the feed-in transformer. Dynamic short-current strength is often expected from the switching device, namely the safety edge. This means that the safety edge deliberately does not react in the event of a short circuit.
  • the load on the switch-disconnector here results on the one hand from the current peak when the current is switched on and on the other hand from the load in the event of a short circuit (usually 1 second).
  • the dynamic load during the electrical switch-on process of an upstream structure often means that the isolating blades and/or the electrical fuses are ejected from the contacts of the safety edge due to the current-dynamic repulsion forces. This creates a hazard for people and equipment.
  • the separating blade or the electrical fuse can be prevented from being ejected by locking devices.
  • a mechanical blocking device for cutting knives is known.
  • the isolating blade is inserted into a contact arrangement, with the blocking device preventing the isolating blade from being thrown out of the contact arrangement in the event of a short circuit.
  • the blocking device has an element for directly transmitting a blocking force in the event of a short circuit the contact arrangement on the disconnect blade.
  • a single-pole or multi-pole NH safety edge which comprises a lower part having current-carrying parts for accommodating 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 touch-safe manner.
  • a separating knife which is firmly connected to the switch cover and which can be inserted into the lower part or removed from the lower part using the switch cover instead of a fuse link.
  • the NH switching strip On the side of the switching cover opposite the pivot bearing, the NH switching strip has a locking device with which the switching cover can be secured against unintentional pivoting out in the closed position.
  • the locking device is designed as a detachable connection between the switching cover or the isolating blade firmly connected thereto and the lower part or the current-carrying parts arranged in the lower part.
  • a power supply circuit breaker for converting connection and disconnection of a power supply by mating and disconnecting two connector housings by operating a switch lever, the power supply circuit breaker having the features of the preamble of claim 1.
  • the power supply circuit breaker has a mechanical locking device. In the locking position, locking means of the locking device cause a form fit between the shift lever and a cover part to prevent the shift lever from pivoting from a first pivot position into a second pivot position.
  • the cover has a cover part and a switch lever, the cover part being movably mounted in the carrier part for transferring the cover part from a first end position into 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, with a disconnecting blade arranged in the cover part or an electrical fuse arranged in the cover part contacting contacts of a lower part that can be connected to the carrier part in the closed position, the contacts being connected to a power supply and a power outlet are connected.
  • the shift lever is pivoted about a pivot axis in the cover part, to transfer the shift lever from a first pivot position to a second pivot position and vice versa, the shift lever interacting with the carrier part to transfer a pivoting movement of the Shift lever in a movement of the cover part relative to the support 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 further develop an arrangement of a carrier part and at least one cover of a switching strip, which has the features of the preamble of patent claim 1, such that this arrangement reliably prevents the isolating blade from being ejected in the event of a short circuit.
  • this arrangement reliably prevents the isolating blade from being ejected in the event of a short circuit.
  • damage occurs to the support part and/or the cover and/or a switching strip having the arrangement.
  • the arrangement according to the invention in particular advantageous developments of the arrangement, should make it possible to retrofit existing safety strips in an uncomplicated manner, in order to protect them against damage in the event of a short-circuit current, in particular when disconnecting knives are used, or to protect the environment around the safety strip 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 support part or between the shift lever and the cover part, 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 the locking position in order to prevent the cover part from moving from the first end position into the second end position.
  • the mechanical locking device secures the shift lever directly against pivoting of the shift lever from the first pivot position into the second pivot position and on the other hand the cover part is secured directly against movement from the first end position into the second end position of the cover part.
  • the mechanical locking device effects 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 cover is particularly well secured in the carrier part.
  • the locking is achieved by an interaction between the cover, support part and locking device, so that no direct interaction of the locking means with other elements of a switching strip, such as the base or components of the base is necessary.
  • the locking means In the locking position, the locking means preferably bring about a form fit 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 preferably be connected to a lower part of the switching strip, the lower part having contacts connected to a power supply and a current outlet, with a lower part connected to the carrier part and an electrical fuse arranged in the cover part or an isolating blade arranged in the cover part being this electrical fuse 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 floor to be turned toward the lower part, in order to fasten the carrier part to the lower part.
  • the locking device By means of the locking device it is possible in the locked position to secure the arrangement or a switching strip equipped with the arrangement against the cover being pushed out/ejected in the event of a short circuit and to enable the cover to be moved in the open position by means of the switching lever. for example, to switch the safety edge and/or to insert or replace a disconnect blade or an electrical fuse in the cover part.

  • the cover has the mechanical locking device or the mechanical locking device is connected to the cover part and/or the shift lever, the mechanical locking device is protected against loss, whereas with a separate mechanical locking device, i.e. one that is not connected to the carrier part or is connected to the lid, there is a risk that it will be lost in the open position.
  • the locking means can certainly have several locking elements. However, it is also quite conceivable that the locking means have only one locking element, in particular the locking means are formed by only one locking element.
  • the locking means have at least one locking element, with the at least one locking element in the locking position causing a form fit between the shift lever and the support part or between the shift lever and the cover part, to prevent the shift lever from pivoting out of the first pivot position into the second pivoted position, and the at least one locking element also causes a form fit between the cover part and the carrier part, to prevent the movement of the cover part from the first end position into the second end position.
  • one and the same locking element causes both a form fit between the shift lever and the support part or between the shift lever and the cover part and a form fit between the cover part and the support part.
