Definitions

  • the invention relates to an electrical device with a safety device according to the claims.
  • pyrotechnic safety devices which disconnect the power supply in the event of an accident of the vehicle by a triggered ignition device (comparable to an explosive charge) from the electrical system to avoid sparking, which could cause further damage.
  • a triggered ignition device component that is part of the vehicle.
  • a pyrotechnic safety device has the disadvantage that it must be triggered only once in the event of an accident and then completely replaced.
  • the invention is therefore based on the object to improve an electrical device with a safety device to the effect that other than electrical incidents are detected and that the safety device can be operated reproducibly.
  • an electrical device with at least one electrical conductor
  • the electrical conductor in its course
  • the interruption in error-free operation of the device is bridged by a fuse element
  • the fuse element is electrically conductive and bridges the broken in its course electrical conductor, so that in error-free operation, a current flow (possibly also a signal transmission) is possible over this electrical conductor.
  • the fuse element takes on a form that has been trained him with its production. This shape is chosen so that the fuse element interrupts the electrical conductor, so that interrupted the power or signal transmission becomes. As a result, further damage can be effectively avoided in an advantageous manner.
  • the error case is the exceeding of a predeterminable temperature, as it arises, for example, in a fire or in very intense heat (for example, sunlight). If the temperature falls below again, is assumed by the fuse element back to the previous form.
  • the electrical device has two electrical conductors, preferably positive and negative conductors, and an electrically conductive fuse element consisting of a shape-memory material is provided which, in fault-free operation, is not applied to the two conductors or only to one the two conductors rests and occupies its original antrainATOR form in an error case and thereby comes to two electrical conductors or to the second electrical conductor to the plant, so that the two electrical conductors are short-circuited.
  • the existing of the electrically conductive material fuse element in error-free operation causes no short circuit between the two electrical conductors and only when, for example, exceeds the fuse element made of a shape memory material its antrainATOR form when exceeding a predetermined temperature, the two electrical conductors are shorted , This can be detected by a suitable detection device, so that in the case of the detected short circuit, the power or data transmission over the two short-circuited conductor is suppressed.
  • an electrical device with at least one electrical conductor that the electrical conductor is interrupted and the interruption is bridged in the fault-free operation of the device by a fuse element actuated electrically conductive bridging element, wherein in an error, the interruption is made by the fact that the existing of a shape memory material fuse element assumes its original antrainator form and the bridging element makes the interruption.
  • the bridging of the interrupted electrical conductor is thus not made directly by the fuse element, but the fuse element actuates the existing of the electrically conductive material bridging element, which in turn carries out the interruption of the electrical conductor in error-free operation. Only when the error occurs when exceeding a predetermined temperature, the fuse element assumes its originally trained form, which causes the bridging element is no longer applied to the electrical conductor, so that thereby the power or data transmission is suppressed via this electrical conductor.
  • an existing from a shape memory material fuse element which causes in error-free operation that an electrically conductive bridging element is not applied to the two conductors or only one of the two conductors and in an error case originally trained Form occupies and thereby the bridging element comes to rest on both electrical conductors or on the second electrical conductor, so that the two electrical conductors are short-circuited.
  • an existing from a shape memory material fuse element which causes in error-free operation that an electrically conductive bridging element is not applied to the two conductors or only one of the two conductors and in an error case originally trained Form occupies and thereby the bridging element comes to rest on both electrical conductors or on the second electrical conductor, so that the two electrical conductors are short-circuited.
  • the fuse element made of the shape memory material assumes its original antrainator form what the The consequence is that the bridging element consisting of the electrically conductive material effects a short circuit between the two electrical conductors which, as already described above, can be detected and appropriate measures can be taken.
  • the electrical conductors mentioned above are electrical lines which have the electrical conductor or conductors in the interior and which are protected from external surges by an electrically non-conductive outer jacket for protection against current surges. Only at the points where the fuse element and / or the bridging element bears against the conductors or can come to rest, the inner electrical conductor is exposed. It is of course important to ensure that this area is protected by suitable measures, such as a housing, from touching.
  • the electrical device is a photovoltaic module and the securing element is arranged within a housing of the photovoltaic module.
  • This application is of particular advantage, since photovoltaic modules, which are arranged on individual solar panels, several of these solar panels can be interconnected to form a solar power plant. If it should come in case of failure to exceed a predetermined temperature (whether by sunlight, heat accumulation or fire) to actuate the fuse element, depending on the variant of the safety device used, the electrical conductor is interrupted or shorted the two electrical conductors, so that in the former case no current flows and in the second-mentioned case the short-circuit is detected by suitable means and countermeasures can be taken.
  • the electrical device may be a merge module of busbars, with which several Solar panels are merged, wherein the fuse element is disposed within a housing of the merge module.
  • the fuse element can not or not only be housed in the photovoltaic module on the solar panel, but also elsewhere.
  • the two electrical conductors 1, 2 (according to FIG. 1 ) not by the fuse element 3 directly, but by a bridging element, which is actuated by the fuse element 3, bridged in the event of an error.
  • the interrupted electrical conductor 1 is not bridged directly by the fuse element 3, but for bridging the existing of the electrically conductive material bridging element is provided, which is actuated by the fuse element 3 in case of failure.
  • the securing element consisting of the shape-memory material may be designed to be electrically conductive or electrically nonconductive.
