Definitions

  • the invention relates to a triggerable fuse for a device to be protected.
  • a fuse can then be triggered.
  • the current flowing through the fuse heats the fusible conductor to such an extent that at least a partial, if not complete, melting of the fusible conductor occurs.
  • This melting is usually associated with the occurrence of an electric arc, with the material of the fusible conductor evaporating. This vapor is deposited elsewhere, with the arc being cooled to such an extent that the current is limited and finally switched off.
  • the melting of the fusible conductor is determined by its material and geometric properties, so that, depending on the material and / or geometry of the fusible conductor, a respective amount of heat Q is necessary to vaporize the fusible conductor.
  • the melting properties and the associated rated tripping currents are described by the melting integral I 2 t.
  • WO 2014/065 763 shows a fuse according to the preamble of claim 1.
  • the invention is therefore based on the object of providing an improved fuse.
  • FIGS. 1 , 2 and 4th each show a schematic representation of a fuse F according to the invention.
  • the fuse F is connected in series with a device 8 to be protected, the series circuit being connected to a supply network with a first potential L and a second potential N different therefrom.
  • the potentials L and N can be any suitable direct voltage or alternating voltage potential. The potentials L and N thus form the supply network to which the series circuit is connected.
  • the fuse F has a first contact 1 and a second contact 2.
  • the second contact 2 is used to make electrical contact with the device 8 to be protected.
  • the fuse F also has a fusible link 5 which connects the first contact 1 to the second contact 2.
  • the fuse F has at least one further contact 3, the further contact 3 being arranged so as to be insulated from the first contact 1 and insulated from the second contact 2. In a non-triggered state of the fuse F, the further contact 3 has no contact with the fusible conductor 5.
  • the first contact 1 is directly connected to the first potential L and the device 8 to be protected is directly connected to the second potential N.
  • the further contact 3 is also directly connected to the second potential N during operation.
  • a fourth contact 4 which provides external triggering, the fusible conductor 5 being caused to melt indirectly or directly when triggered.
  • the fusible conductor 5 is severed.
  • the arc that occurs in the process passes over to the further contact 3 in the area thereof.
  • this is favored by the fact that the further contact 3 essentially has the potential N, so that here the voltage between the fusible conductor 5, which essentially has the potential L, is greater than the potential of the second contact 2, which essentially has the has the same potential as the fusible conductor 5, a reduction occurring here due to the drop in potential across the protective device 8.
  • this secondary arc will have a larger current, so that a safe separation of the fusible conductor and thus protection of the device 8 is guaranteed.
  • the fourth contact 4 is here - preferably as in FIG Figures 1 . 2 and 4th shown - in close proximity to the contact 2 and the further contact 3.
  • the sequence can be suitably chosen, e.g. the further contact 3 and the second contact 2 can be adjacent to the fourth contact, or the fourth contact is arranged above the further contact and thus the further contact has the second contact 2 and the fourth contact 4 as a neighbor.
  • the fourth contact 4 is also made insulated in the fuse.
  • the fourth contact 4 can serve as an ignition spark gap for the area where the contact 3 approaches the fusible conductor 5. A triggerable fuse is thus obtained.
  • the fusible conductor 5 or the contact 3 can serve as the electrical counter-contact to the fourth contact 4, but without being restricted to this.
  • a further contact (not shown) can also be provided, which is isolated from the second contact 2, the further contact 3 and the fourth contact 4.
  • ignition now occurs between the fourth contact 4 and the further contact 3, between the fourth contact 4 and the fusible conductor 5, or between the fourth contact 4 and the further contact (not shown).
  • the ignition can also be through a resistive support, such as in the DE 10146728 or by means of a transformer high voltage pulse as in the DE 50 2005 008 658 shown by the applicant.
  • suitable triggering can be provided by means of a correspondingly configured trigger device 9.
  • the trigger device 9 can be made to trigger.
  • a wide variety of monitoring mechanisms for electrical circuits and devices can be used to control the trigger device 9. Examples are arc detection and temperature monitoring.
  • ignition can be triggered with relatively little energy, as a result of which an arc with high power arises between the further contact 3 and the fusible conductor 5, as a result of which the fusible conductor 5 separates so far that the current is switched off.
  • a primary arc is created there. This initially burns between the ends of the fusible conductor 5 created at the point of separation. Under the action of the arc, the separated ends of the fusible conductor 5 burn down, the arc being lengthened.This process can take place at different speeds depending on the design and location of the separation. As a result of the ionization caused by the arc, the further contact 3 is formed as the (new) base point of the arc, if not already done.
  • the current flow through the device 8 to be protected is thus interrupted. This ensures that, in the event of a fault, the device 8 to be protected only has to carry the energy corresponding to i2t that is necessary for melting and developing the first arc. If external triggering is provided by means of the trigger device 9, the current does not play a role in relation to the device 8 to be protected. This energy is much less than the energy that would flow through the device until the fuse was deleted (permeability integral).
  • the fusible conductor 5 has a predetermined breaking point in the area of the further contact 3.
  • the fusible conductor 5 will now melt in the area of the predetermined breaking point 6.
  • Such predetermined breaking points 6 can be created, for example, by tapering (s) and / or perforation (s) of the fusible conductor 5 be realized.
  • An arc is created and the arc in turn burns off the two ends of the fusible conductor 5 and is thereby lengthened.
  • the arc causes ionization so that the arc can select contact 3 as the new base point or due to the low resistance (e.g. with appropriate dimensioning) and / or arrangement relative to the second contact.
  • the current flow through the device 8 to be protected is thus interrupted.
  • the fusible conductor 5 is filled with an extinguishing medium, in particular with sand and / or POM (polyoxymethylene). This improves the switching properties with regard to the switching capacity and also the speed, since an improved cooling of the arc is now provided, whereby the switching capacity and the switching speed can be improved.
  • an extinguishing medium in particular with sand and / or POM (polyoxymethylene).
  • the further contact 3 has a disk-like design, the fusible conductor 5 being guided in an indentation or through an opening.
  • the production can be made particularly simple and thus inexpensive.
  • the contact can be designed as a disk with an essentially circular opening.
  • the fourth contact 4 has a disk-like design, the fusible conductor 5 being guided in an indentation or through an opening.
  • the production can be made particularly simple and thus inexpensive.
  • the contact can be designed as a disk with an essentially circular opening.
  • the fuse F can furthermore have an auxiliary fusible conductor 10 which is in electrical connection with the first contact 1 and which is in electrical connection with the fourth contact 4. This allows the operation z. B. with respect to spark gaps as the device 8 to be protected.
  • This embodiment is particularly suitable for protecting auxiliary circuits of high-power electrical devices. It would be conceivable that the electronic measuring, control, regulation and safety devices of large motors and other high-performance consumers that have low-power auxiliary circuits, but where the failure of the auxiliary circuit should lead to an immediate shutdown (emergency shutdown) of the main device.
  • Ignition circuits are usually with regard to their electrical parameters, e.g. their electrical cross-section, designed to be significantly smaller than the main electrical path of the spark gap, since the backup fuse must always be dimensioned for the maximum surge current pulse to be diverted. It may therefore be necessary to secure ignition circuits with additional protective devices, which requires additional installation space. Furthermore, the triggering of a protective device in the ignition circuit must also be signaled and given. This results in a considerable additional effort, which can be minimized by integrating the auxiliary fusible conductor as a fuse for the ignition circuit in the backup fuse, and an additional gain in safety is generated by the spark gap 8 being completely separated electrically.
  • the trigger device 9 for a spark gap can be used as the device 8 to be protected, as in FIG Figure 4 be executed shown.
  • the fusible conductor 5 and the auxiliary fusible conductor 10 can be guided in a wire-like manner, at least in sections, in parallel, or as in FIG Figure 3 shown on the left-hand side, the auxiliary fusible conductor 10 can be separated in sections from the fusible conductor 5 as a part.
  • the auxiliary fusible conductor 10 can be correspondingly separated in sections from the fusible conductor 5 by punching, cutting, milling or the like.
  • auxiliary fusible conductor 10 can as in Figure 3 Shown on the right, sections also surround the fusible conductor 5 in a spiral manner.
  • the auxiliary fusible conductor 10 should run isolated from the fusible conductor 5, at least in the area where the contact 3 approaches the fusible link 5, so that an essentially defined ignition point is present.
  • the fusible conductor 5 and also the auxiliary fusible conductor 10 can have one or more predetermined breaking points 6 in the area of the further contact 3 or in the area of the fourth contact 4.
  • the fuse F according to the invention can particularly advantageously be used in a fuse arrangement A, for example as in FIG Figure 4 are used, which in addition to the fuse F also has the device 8 to be protected and a trigger device 9 which is connected to the fourth contact 4 and enables "external" triggering, ie triggering that is not directly owed to the main conduction path .
  • the device 8 to be protected can have an overvoltage protection device, for example a spark gap and / or a varistor and / or a transient voltage suppressor diode.
  • an overvoltage protection device for example a spark gap and / or a varistor and / or a transient voltage suppressor diode.
  • a wear monitoring device 12 is also provided, which is designed, for example, as a contact protected with a degradable material.
  • the trigger device 9 is then connected, for example on the output side, to the wear monitoring device 12 of the spark gap 8 to the fourth contact 4.
  • auxiliary fusible conductor 10 If the auxiliary fusible conductor 10 is overloaded in the area of the approach between the contact 4 and the fusible conductor 5, an arc is created between the ends of the fused-on auxiliary fusible conductor 10.This arc ignites a second arc between the fusible conductor 5 and the contact 3, which is used to burn off the fusible conductor 5, so it triggers the fuse.
  • the auxiliary fusible link 10 can be used in the area of the approach of the Contact 3 on the fusible conductor 5 have a predetermined breaking point 6, which breaks first when the fusible conductor is overloaded, so that a first arc occurs at this point.
  • the auxiliary fusible conductor 10 can be energized and triggered by switching devices in the device to be protected or a trigger device 9. This gives a triggerable fuse F.
  • the usual mechanisms for isolated implementation of potentials can be used to introduce the isolated potentials of the further contact 3 and the fourth contact 4.
  • the layered structure of metal plates and insulating plates with a locking end plate at the end is particularly advantageous.
  • the different potentials can be introduced via the stacked and insulated plates.
  • the plate stack can e.g. be screwed.
  • the triggering of the fuse can be signaled according to the usual mechanisms.
  • the presented invention can be used particularly advantageously in the field of electromobility as well as the generation of electrical energy by means of photovoltaics. It is often found here that vehicles or systems or devices should meet certain safety criteria in order, for example, in the event of an accident or fire, to avoid any danger to occupants or helpers.
  • the invention can then readily provide an automatically or externally triggerable and high-performance shutdown of the energy source as an example of a device 8 to be protected.
