Definitions

  • the subject matter relates to a disconnecting device for an energy line, in particular a motor vehicle power line, comprising at least one separating point arranged spatially between a first and a second connecting part in a closed state of the separating device and a bolt entering the separating point immediately after the separating of the connecting parts.
  • the subject relates to a method for separating an energy line.
  • the electrical protection of energy conductors represents a safety-relevant area of motor vehicle technology with regard to ensuring the safety of vehicle occupants. must be quickly disconnected from the vehicle battery in the event of an accident. If this is not ensured, short-circuits with briefly very high currents can occur in the event of accidents. The high short-circuit currents lead to the formation of arcs. These must be deleted reliably so as not to endanger the safety of the vehicle occupants.
  • cut-off devices are frequently used in which the power lines are cut by pyrotechnic cut-off devices in the event of an impending short circuit.
  • the separation of the energy lines with the aid of the pyrotechnic separating devices is usually achieved either by mechanically severing the energy line or by accelerating a bolt out of a cylinder, a closed current path being formed between the bolt and the cylinder by the separating device, For example, the bolt is cut.
  • a disadvantage of the conventionally used pyrotechnic separation devices is the fact that arcs can form between the gap at the separation point at the moment of disconnection of a current-carrying line, as a result of which the connection parts remain electrically connected to one another at least temporarily. This is often the case, in particular, in high-voltage applications in electric or hybrid vehicles, since the formation of arcs is particularly favored here because of the high currents and potential differences.
  • the fact that the flowable medium at least partially flows around the separation point at the moment of separation is intended to ensure that the flowable medium spreads out in the air gap which forms between the two connection parts, as a result of which the occurrence of an arc is suppressed or an arc which has arisen can be extinguished.
  • a disadvantage of the described method is that the extinguishing or suppression of arcs only takes place reliably at limited voltages or currents, as a result of which the area of application of the known method is limited, in particular to 48 V electrical systems.
  • the object of the object was to provide a disconnecting device which enables the most reliable disconnection of a current-carrying line, even in high-voltage applications, in particular above 100 V, preferably above 400 V.
  • the separating device can be designed in such a way that the first and second connecting parts are current-carrying components of a motor vehicle power line.
  • the first and second connecting parts can also be live components of power lines of other vehicles, of building installations, of electrically operated machines or signal boxes.
  • the object-related separation device be used in addition to the flowable medium has a bolt which suppresses the formation of arcs by moving into the separation point and / or extinguishes arcs by moving into the separation point.
  • the bolt can be formed from a dielectric material with low dielectric strength, preferably a plastic, a ceramic or a resin.
  • the insulation element can preferably be formed from an insulation material with an dielectric strength of at least more than 5 kV / mm, preferably more than 20 kV / mm, particularly preferably more than 50 kV / mm and / or a specific electrical conductivity of at least less than 10 -5 S ⁇ cm -1 , preferably less than 10 -10 S ⁇ cm -1 , particularly preferably less than 10 -15 S ⁇ cm -1 .
  • the separating device have a counter bearing in addition to the first pin, the two pins being arranged in a closed state of the separating device preferably on opposite sides of the separating point separated by the separating point.
  • the bolt and the counterbearing move relative to one another after the connection parts have been separated, in particular for the bolt to move toward the counterbearing, whereas the counterbearing is stable in place.
  • at least the bolt moves into the separation point after the connection parts have been separated in such a way that the bolt is arranged as precisely as possible on the counter bearing and thus an arc which forms in the region of the separation point can be "pinched off" safely and reliably.
  • the separating device only has to have one drive, since the counterbearing can be fixed, for example, in the housing of the separating device, during which the bolt can be movably mounted in the housing and is accelerated by the drive in the direction of the separation point.
  • the bolt and the counter bearing have complementary, in particular precise, shapes in their contact area, the bolt preferably having a V-shaped end section while the counter bearing has a complementary V-shaped end portion.
  • the bolts and counterbearing can also have other shapes in their contact area, such as, for example, sickle or semicircular shapes, or three, four or five points.
  • the contact areas of the bolt and counterbearing should be shaped as complementary as possible, in particular to each other.
  • bolts and counter bearings are preferably arranged on a common axis with the separation point, in particular one essentially perpendicular to the current path between the first and second connection parts.
  • value and counter bearing are preferably placed on the most exact possible alignment of the axis of the bolt, since reliable and safe extinguishing and prevention of arcing can only take place if an exact alignment with one another is observed.
  • the bolt and counterbearing are preferably arranged substantially equidistant from the separation point in the closed state of the separating device. This enables the pin and counterbearing to be arranged at the separation point as quickly as possible, which means that an arc between the connection parts can be extinguished shortly after the separation.
  • the separating device advantageously has a current carrying capacity of more than 50 amperes, preferably more than 100 amperes, in particular more than 400 amperes, when closed.
  • the disconnection device is advantageously designed such that a potential difference of over 48 V, preferably over 100 V, in particular up to 500 V, is present between the connection parts in the open state.

  • the connecting parts can be shaped for connection to electrical lines and cables and have cable lugs for receiving the cables.
  • the connecting parts can also be integrated into an on-board electrical system. In the closed state of the separating device, an electrical current flows between a consumer and a current source via the connecting parts and a separating point.
  • the disconnection point In order to ensure a safe disconnection, the disconnection point must have a lower breaking strength than the housing or the connection parts.
  • the separation point is a predetermined breaking point, in particular at least a taper or recess at the separation point or a soldering point between the connection parts.
  • the dividing line between the connection parts should run along the separation point and the gap between the connection parts should be formed, which separates the current path. This gap runs along the separation point.
  • the predetermined breaking point can be, for example, a taper along a line over the surface of a connecting part. Connection parts can also be soldered to one another and thus form the separation point. It is also possible that the separation point is tapered to at least two points, each with a connection part, and the taper is broken up by the pressure of the flowable medium and the separation point is detached from the connection parts.
  • the separation point be notched in relation to a respective connection part, such that the respective recess, groove or the like runs along a predetermined bending line of the separation point.
  • the nominal bending line defines where the connecting parts are to be bent. In this way, it can be precisely defined which space the separation point occupies when opening, so that this space can be made available in the guide housing.

  • the bolt be arranged displaceably in the guide housing along the axial direction of propagation of the guide housing.
  • the bolt can be accelerated by the pressure impulse of the drive in the direction of the flowable medium and exert a pressure thereon that is sufficient to separate the separation point.
  • the bolt can prevent a gas bubble, which forms, for example, before the drive in the event of activation, from moving through the flowable medium in the direction of the end point without the flowable medium being accelerated sufficiently towards the separation point.
  • the flowable medium preferably has the property that it is incompressible.
  • the flowable medium is pressed in the direction of the separation point by the drive in such a way that it breaks up the separation point and surrounds the separation point. Because the flowable medium is preferably incompressible, it is possible to make the drive as small as possible. The entire energy of the drive is exerted directly on the separation point.
  • the flowable medium is a liquid or a pourable bulk material, in particular sand, and / or is liquid, pasty, foam-like, gel-like or granular.
