Definitions
- the invention relates to a device for operating voltage-independent generating a safe, low-resistance electrical short circuit, comprising two electrical, in particular plate-shaped
- connection parts which lead to a different potential, wherein between the connection parts an insulation gap is formed and the desired short circuit via a, at least partially, penetration or destruction of the insulation distance is realized, according to claim 1.
- the realization of a targeted electrical short circuit is a common method for a variety of electrical devices to ensure a safe switching state.
- Fail-safe is a well-known and common method for
- the heating is used to trigger the short-circuit.
- Usual are here, for example, spring-biased movable contacts, which are released by the heating of solder or wax.
- the control of semiconductors or of hybrid short-circuiters which consist of semiconductors and mechanical short-circuiters, is also known.
- the time to reach the short circuit state can be significantly reduced.
- low cost semiconductors in many cases do not have sufficient current carrying capacity.
- the realized short circuit is also not low-impedance and it is the effort to control and protect the semiconductor and their EMC-safe use in many applications high.
- overvoltage protection protective devices are furthermore known in which e.g. heating-expanding materials are used to cause movement of contacts.
- the targeted control of such materials, for example with an additional heating element is known.
- the short circuit should be active, that is, it can be deliberately brought about with the help of an external or internal activation, and on the other hand it can also be passive, independently of achieving at least one defined condition.
- the active control is to be realized by as diverse as possible individual criteria, but also by OR links of these criteria.
- the short circuit device to be created without expensive mechanical
- the short circuit to be realized should also enable a selective disconnection of overcurrent protection devices and be suitable for the conduction of continuous currents. Accordingly, it is desired that the device provide a low resistance galvanic connection suitable for persistent currents. Also, the parts required for the short circuit and the control should be executable as a ready-to-connect supplementary unit.
- the basic idea of the invention is to distinguish between two, e.g.
- plate-shaped parts which lead a different electrical potential, at least in each case an insulating film and an exothermic mass, which is preferably also executable as a film to arrange.
- the connecting parts with different potential have a distance of a few 10 ⁇ up to a few 100 ⁇ .
- the mentioned exothermic mass is preferably close to ground or at ground potential.
- the mass can now be activated by a voltage pulse, a current pulse, by a mechanical shock or pressure or an intense light pulse or even during or by electrical discharge and diversion processes.
- the exothermic mass is quasi passively subject to activation even when reaching a defined temperature.
- the reaction of the exothermic mass leads to melting or to a deformation of the insulating film forming the insulating film within a very short time, whereby the potential separation is canceled and a short circuit between the floating parts can be produced.
- the realization of the short circuit can be described by additional design measures and in the embodiments
- connection parts are arranged closely adjacent to the isolation path.
- the insulation gap can, as already stated, be formed as an insulation film, but also as a film-like coating.
- the aforementioned exothermic mass which releases its exothermic energy when energized and the
- At least one of the connecting parts can be under mechanical prestress, so that when the insulation section is destroyed or deformed, the connecting parts come into contact with each other via a mechanical movement that then occurs.
- this can be a sandwich arrangement with the insulation gap, which in turn can also be formed by a film.
- the exothermic mass is designed and dimensioned such that sufficient heat is released within a period of about 1 to 10 ms in order to melt or significantly deform the insulation film or insulation layer.
- the exothermic mass is integrated in one or both of the connecting parts. Furthermore, arranging of easily melting metals or metal layers can take place in the area of the formation or arrangement of the exothermic mass.
- the short-circuiting device therefore consists of two e.g. plate-shaped electrically conductive parts with generally different potential, between which at least one insulating film and an exothermic mass, which is preferably also formed as a film is brought.
- the two electrically conductive parts with generally different potential can be connection or connection elements of the device to be protected by short circuits or else a component of a connection-ready supplementary unit "short-circuiter".
- the electrically conductive parts have a distance of a few 10 ⁇ up to a few 100 ⁇ .
- One or both parts can be under a mechanical preload, which in the simplest case is created by the joining of the parts and the material properties.
- the thickness and the material properties of the electrical insulating film determine the maximum rated voltage and the transient dielectric strength of the short-circuiting device. In addition to the breakdown properties of the film are of course the rollover properties and the
- the exothermic mass develops after its active or passive activation immediately at the activation site within a period of less than 1 ms so much heat that the insulation film melts.
- the exothermic mass in film form and with active ignition at only one point of the mass, the exothermic reaction within the film continues at high speed, so that even with large required contact surfaces generally one activation point is sufficient. Due to the rapid release of the heat, the influence of the heat capacity and heat conduction of the electrically conductive connection parts (short-circuit contacts) is almost negligible.
- the energy input can be considered almost adiabatic and the
- the exothermic mass is preferably close to ground or at ground potential.
- the mass or film can also be integrated in an electrically conductive connection part, so that only the insulation film determines the spacing of the conductive parts.
- the film itself may be electrically conductive and similarly thin designed as the insulating film, so that the cost of introducing the exothermic mass is negligible.
- the insulating film and the exothermic film can also be designed as a composite material in sandwich form with a suitable design of the electrically conductive parts.
- the insulation film can also be exothermic on both sides
- Channels can be integrated into the electrically conductive connection plates. In the case of an electrically conductive exothermic mass, it may also be designed to accommodate or specifically displace the melt.
- the targeted influence on the melt of the insulating material is useful even at low operating or residual stresses in the fault state, eg in arcs, so that even with the low film thicknesses no minimum air or sliding distance remains despite molten film.
- the pure displacement effect of the melt of the insulating film is supported by the heat of reaction, the first current flow, possibly with minimal discharge formation, and by a minimum bias of the connecting parts.
- the reaction area also easily melting metals (low heat conduction, low heat capacity, low melting temperature), for example, as a coating of the films, the exothermic film or the connecting parts are used. The resulting molten metal bridges the minimum gap after melting the insulation film.
- thermal processes are used to melt or move parts.
- the presented arrangement allows the bi-f unctional use of the exothermic reaction for the preferred realization of a short circuit.
- the reaction can be triggered on the one hand purposefully and independently of the environmental conditions of the film or the device, for example by a remote control.
- influence or reference variables of the immediate surroundings of the film or signal quantities of the device can be used directly or indirectly. The application possibilities are therefore almost unlimited.
- the purely passive reaction of the film upon reaching a limit temperature can be used, for example, in components or devices in which higher temperatures lead to overloading or a fire hazard. This feature has a redundant effect in many applications where active activation fails.
- the film can be placed in direct thermal contact with the component at risk of overload, or the heat via a thermal coupling.
- the passive thermal reaction of the film can also be used via an additional heating element. Due to the very low heat capacity and low heat conduction, the exothermic reaction can be achieved only with a nearly selective energy coupling and low power. The required power corresponds to only a fraction of thermally sensitive enamel, such as solders, waxes etc.
- the mass can, for example, by a
- Voltage pulse, a current flow, by mechanical shock, an intense light pulse or electric discharge or recharge processes are activated.
- a voltage pulse can be generated in the simplest case by a defined flashover distance or by means of discrete components which respond to overvoltages.
- a current flow can be generated by the targeted electronic or mechanical connection, for example, the supply voltage of the device or an available auxiliary snapssario generated in the exothermic mass. For this is the
- Firing pin or be used by strong vibration These options therefore allow the use of a simple mechanical or electronic shutter, for example by applying the mass with a current flow or a charge, which may be remotely operated. In addition to the remote control and auxiliary sizes can be used.
- Components such as thermal switches, NTC, PTC, GDT 's , varistors, Hall sensors, piezo elements, etc., which can react to internal load variables defined, are connected internally or deliberately switched from the outside. Also suitable for igniting the mass is the thermal overload of current bridges, for example, fusible conductors, which can be used both for thermal heating or for spark formation.
- Triggering an activation signal e.g. allow at very fast overload the ignition of the mass can also be done by the destruction of the components themselves and the device can be spent by the realization of a defined short circuit in a safe state.
- the rollover or destruction of electrical or electronic components generally generates sparks, arcs or hot ionized gases.
- the accompanying phenomena could be used directly for an activation of the mass.

- Fig. 1 a basic principle arrangement for realizing a short circuit is shown.
- the plate-shaped connection parts 1 and 2 can be existing electrically conductive parts of the device to be protected or also additional parts which are inserted into the device.
- the essential components provide the exothermic mass, e.g. in
- Foil form 3 and the insulating film 4 is. Both parts each have a thickness of only a few 10 ⁇ .
- the part shown as a spring element 5 is not mandatory. Due to the short distances, a clamping connection of the parts or even the intrinsic elasticity of the parts is generally sufficient.
- the distance between the connecting parts 1 and 2 can be reduced to the thickness of the insulating film 4.
- the insulation film 4 and the connection parts 2 are designed so that the electrical voltage resistance between the connection parts 1 and 2 corresponds to the electrical breakdown voltage of the insulation film. In Fig.
- Fig. 1 is limited to the passive triggering of the exothermic reaction, in the case of heating the film 3 to the reaction temperature. This heating could be done for example by thermal conduction through the connection part 1. Upon reaching the reaction temperature, the Foil 3 within a few ⁇ to ms release a sufficient amount of energy to melt the insulating film 4 in the contact area.
- the exothermic mass 3 is electrically conductive both before the reaction and after the reaction. However, this is not absolutely necessary due to the small dimensions of the film 3. In general, at one
- melt residues of the film 4 are generally displaced from the contact area by the applied pressure of the clamping connection.
- the distance between the electrically conductive parts 1 and 2 is also independent of the properties of the mass.
- Fig. 2 shows an arrangement in which the insulating film 4 is disposed between two sheets of exothermic mass 3.
- the insulating film can be supplied with the required heat of fusion from both sides.
- a film 3 may, for. B. are used exclusively for passive triggering by heating and the other film can be actively controlled. If required, both sides can also be used for passive monitoring at the same or different trip temperature.
- both sides can also be used for passive monitoring at the same or different trip temperature.
- stronger insulation films can be destroyed and that the destruction of the insulation layer can be accelerated.
- such a high radiation intensity is produced that the film on the opposite side of the insulating film is automatically activated, e.g. in optically transparent insulation films 4.
- Fig. 3 an arrangement is shown, in which the connecting parts or the film 3 is additionally coated with an electrically conductive material with low melting temperature 6, for example, low-temperature solder.
- the solder can also be added as an additional film.
- This additional material can realize several functions.
- the material can serve as a defined heat transfer barrier to the terminals to the optimally transfer resulting heat of reaction to the insulation film and the additional material.
- low-melting material can be used for rapid and large-scale
- the melt can also serve for permanent soldering of the terminals 1 and 2 and thus in addition to the electrical function and a mechanical function after

- FIG. 4 shows such an arrangement of cavities / channels 7 in the connection 2.
- the real contact surface remains sufficiently large.
- Fig. 5 a similar arrangement with a larger cavity 7 is shown.
- a mandrel 8 can be mounted in the cavity.
- the material 3 deforms very strongly, causing a kind of deep drawing process of the material into the cavity 7.
- these are already drawn into the cavity before melting and destroyed on the mandrel 8, so that the short circuit is realized even before complete melting of the insulating film and also before the displacement of the remainder of the film.
- Fig. 6 shows a similar arrangement in which the insulating film has a suitable recess 9 in the region of the cavity, whereby a movement of the insulating film 4 by the exothermic film 3 in the
- FIG. 7 shows the arrangement according to FIG. 6 after the exothermic reaction and the deformation of the part 3.
- the active control of the exothermic mass can, as already
- Fig. 8 shows a possible basic arrangement, wherein the
- Activation is done relatively centrally on the film 3. This ensures, in particular for relatively large areas, that the necessary heat of fusion for the film 4 is available almost at the same time due to the internal reaction speed within the film at the two edge regions.
- the film 3 can also be activated at an edge region or at several points. The activation of the film 3 takes place in the arrangement via an electrically conductive connection line 11.
- This line can be soldered to the film 3, clamped or even just hang up. There may also be a minimum distance between the conduit 11 and the part 3.
- the cable cross-section can be very small ⁇ 1mm 2 .
- the requirements of the electrical insulation of the line 11 with respect to the connection part 1 is negligible, as long as the contact or the distance to the part 3 is guaranteed or less.
- the component 10 in the electrical connection line 11 may be located within the device to be protected or outside.
- the component 10 itself may be a sensor or a controllable element which responds to requirements within the device to be protected or external conditions or signals.
- the component 10 may be an electrical switch or mechanical switch. By its operation, a potential is applied to the film 3, which differs from that of the film 3 and the terminal 1, whereby a charge compensation takes place. The film 3 is thereby by the current flow or the discharge
- the part 10 may also be designed as NTC, PTC, GDT, varistor, Zener diode, thermal switch, piezoelectric elements, etc. Due to the choice of the sensor, various ternal or external variables are used for activation. Due to the very low energy requirement for activation, also wireless methods (transmitter-receiver) can be used without restrictions.
- the additional element 12 may be designed, for example, as an impedance, spark gap or else as a fused wire with a defined I 2 t value. This allows, regardless of the amount of charge available, a defined generation of sparks, which cause the reaction of the film 3 very effectively and very quickly.
- the speed of triggering the film can be compared to the heating of the film by a
- lasers or firing pins can of course also be used, for example. acting analogously to the fuse on the film 3 and trigger targeted.
- FIG. 10 and Fig. 11 show arrangements with a housing, which for a subsequent attachment of the short-circuiting to a
- a protective device / component are suitable.
- the known from Fig. 1 arrangement is introduced into a housing 13 made of metal.
- Connection element 1 is directly connected to the housing.
- the housing 13 can also be used as a connection element 1 itself.
- the terminal 2 is insulated from the housing 13 led to the outside.
- the bushing 14 serves for insulation and the part 15 for the outer connection.
- a further connection 23 can be guided through the housing 13, which can be used to actively activate the film 13 with an outer component 10. The passive activation of the film 3 takes place by the heat transfer from the housing or connection 1 to the film 3.
- Fig. 11 shows a similar arrangement, however, the housing 13 is made of insulating material and has two passages for the outer
- the passive heating of the film 3 can take place via the connection 16.
- the housing 13 may also have an outwardly directed heat transfer element 24 include. This can be electrically isolated or electrically connected to the connection element 1.
- FIGS. 12 and 13 show an exemplary use of the short-circuiting arrangement with a component to be protected in a common housing.
- the housing has in each case three connections 17, 18, 20, which are all led separately to the outside in a housing made of insulating material 22. This allows separate external wiring of the
- the short-circuiting device can also be wired inside the housing, whereby the outer connection 20 would be omitted.
- a surge arrester in particular a varistor 19, has been selected to explain the function. It is well known that varistors can become very hot or overturn at the risk of overloading.
- a flashover which is connected to a spark discharge 21, indicated.
- the film 3 is heated directly through the varistor.
- the connection 1 of the short-circuiter can in this case simultaneously be the connection plate 18 of the varistor.
- the insulating film 4 melted and causes a short circuit between the terminals 18 and 20. Will the
- Varistor is bridged by a spark discharge 21, the terminals 18 and 20 are also low-resistance short-circuited after the activation of the film 3 by the flashover, whereby the bursting of the
- Housing 22 can be prevented due to an open arc.
- the insulating film 4 may be cast in the housing 22 to increase the flashover resistance between the terminal 18 and the terminal 2 or 20.
- Fig. 13 shows a similar arrangement as Fig. 12, but the supernatant of the insulating film 4 between the terminal 1 and the film 3 and the terminal 2 is pronounced as a sliding spark gap.
- the spark gap can be dimensioned so that with a corresponding connection of the terminals 17, 18, 20 avoided an undefined flashover of the varistor between the terminals 17 and 18 and the film 3 is ignited immediately to realize a short circuit.
- the endangerment of the housing 22 due to the development of pressure during an undefined Impact can be further reduced by this measure.
- GDT "s or other voltage switching elements can be used.
- for a bi-f unctional triggering of the short within a device can be used for activation of course other internal or external sensors.
- pure OR operations can Even discrete components can also be used to implement AND operations for activating the short circuiter (without logic or PLC units).
- the terms used in the description and in the embodiment of an active or passive activation of the exothermic mass are based on the manner of introducing a corresponding activation energy. Passive mechanisms are to be understood here, which result in the usual use of the device to be protected without specific intervention in the risk of overloading or by the overload itself. This can be the case of a varistor, for example, the heating due to a current load.
- the exothermic mass e.g. designed as a reaction foil ignites it as a result of the passive heat input at its ignition temperature without additional ignition aid.
- the protective mechanism can optionally be triggered against damage to the component to be protected. Under passive activation but also the triggering due to the sparking at an outer rollover of the varistor should be understood, in which case there is already a damage to the actual component and the protective measure is only to mitigate damage, for. to avoid a bursting of a housing.
- Active mechanisms are those that are independent of the state of the components. These can be current, voltage, power of the corresponding component, which should be protected accordingly. However, active mechanisms are also those which can be used outside the passively protected component for triggering.
- Short circuiter which is used passively to protect an overvoltage protection device, also be used by an active control to extinguish an external arc fault, which would not operate on the passive release mechanisms, eg due to the local distance the short circuiter.
- an active control but also no separate ignition device is necessary. With an active ignition, the activation always takes place via a separate ignition device.
- the preferred reaction film used as an exothermic mass should have a small thickness and allow a fast, self-propagating exothermic reaction.
- the film should be both passive and active to their exothermic reaction initiation can be performed, with a pressure to avoid development and primarily to ensure heat development.
- reaction foil e.g. the product Nanofoil (registered trademark) can be used.
- Dielectric strength and has a continuous use temperature that corresponds to the application of the device to be protected.
- PE, PET, PS, PP, PSU, PA6 and PC films with an electrical breakdown strength of> 30 KV / mm are suitable here.
- reaction film as an exothermic mass and the electrical insulation film can be sandwiched, i. also such that reaction films are located on both sides of the insulating film.
