Definitions

  • the invention relates to a method for short-circuiting two Potential points according to the preamble of claim 1. Furthermore The invention relates to a short-circuiter according to the preamble of claim 4 and a short-circuit proof power semiconductor module according to the preamble of claim 11th
  • the present invention is based on the object fast and reliable method for short-circuiting two To create potential points according to the preamble of claim 1, which does not require separate arc detection.
  • the arc ignites Pyrotechnic center, which releases large amounts of gas exothermic reaction.
  • the present invention is based on the object a short-circuiter according to the preamble of claim 4 create that can be produced easily and inexpensively and a safe and permanent short circuit with minimal Establishes contact resistance and in particular the implementation of the method according to claim 1.
  • This object is achieved in a short-circuiter according to the invention solved according to claim 4 in that one of an arc energy released in a spark gap Energy storage can be supplied and the energy storage through this energy can be released.
  • the object of the present invention based on a short-circuit-proof power semiconductor module to create the preamble of claim 11, in which a short-circuiter, especially according to claim 4, in the event of a fault Short circuit causes.
  • This object is short-circuit proof in accordance with the invention Power semiconductor module according to claim 11 solved in that that one of an arc in a spark gap released energy can be supplied to an energy store and that the energy store can be triggered by this energy.
  • Fig. 1 is a cross section of an embodiment for an inventive short-circuiter according to claim 4 Implementation of the short-circuiting method according to the invention two potential points according to claim 1 shown.
  • the short circuiter has two electrical connections 1a, 1b. This are fixed relative to each other, e.g. through a housing that in the drawing is not shown.
  • a metallic contact element 2b is in a starting position.
  • the Contacting element 2b is movable, whereby the mobility by metallic guide elements 2a and the connections 1a, 1b a shift between the starting position and an ending position is limited.
  • Contacting element and guide elements are preferably radially symmetrical with respect to the axis A.
  • One through the contact element 2b and the connection 1a formed cavity is filled with an energy store 4, that contains a stored first energy.
  • an energy store 4 that contains a stored first energy.
  • material for the energy storage come e.g. Standard pyrotechnics in question as they are used in rifle cartridges.
  • a spark gap 3 is between a shape 21 of the contacting element 2b and the connection 1b formed.
  • the energy store 4 is preferably able to generate large amounts of gas and / or a shock wave when the first energy stored in it is released.
  • the shock wave or an emerging gas pressure move the contacting element 2b towards the opposite connection 1b.

  • the igniter protrudes through a hole in the contact element 2b into the spark gap 3 into it.
  • the igniter 7 is ignited, which then further Components of the energy storage activated, for example a gas generator. It is advantageous with this configuration that that the requirements for the properties of energy storage regarding sensitivity on the one hand, which among other things determines the ignition temperature, and the energy release on the other hand, by the amount and type of releasable Energy and the time required for release, can be influenced and selected independently of each other.
  • a Energy storage used by a pyrotechnic and a Element made of a shape memory alloy contains.
  • the pyrotechnic center is chosen so that at the release of the first energy stored in it primarily heat is produced. This warmth drives again the SMA element.
  • SMAs are below a critical one Temperature in a martensite structure. In the martensite phase they are relatively soft and easily deformable. When warming the SMA go through a transition temperature Phase transition (weak first order) to a more symmetrical one Austenite phase over. In doing so, they deform back into one original condition with a high modulus of elasticity.
  • Stack of SMA disc springs with different transition temperatures are already for gradual pressure generation in a different context been used (US-A-4,897,006).
  • Material and shape of the SMA element are now selected so that the SMA element before the short circuiter is triggered in the martensite phase is present and the contacting element is fixed in the initial state and this with a transition to the austenite phase in the final state emotional.
  • the phase transition is preferably irreversible, so that the contacting element after the phase transition is kept in the final state by the SMA element.
  • the transition temperature is selected in such a way that it can only be heat released by the pyrotechnic center after activation of the pyrotechnic center is reached.
  • Fig. 5 shows schematically an inventive power semiconductor module according to claim 11, wherein a short-circuiter after Claim 4 is used when an overvoltage is present a short circuit between the connections 1a and 1b to bring about these connections 1a and 1b.
