Definitions

  • the invention relates to an electrical interrupt switching element, in particular for interrupting high currents at high voltages, with the features of claim 1.
  • interruption switching elements can be found, for example, in power plant and automotive engineering, as well as in general mechanical and electrical engineering in control cabinets of machines and systems, as well as in the context of electromobility in electric and hybrid vehicles, but also in electrically operated helicopters and airplanes for defined and quick disconnection of electrical power circuits in an emergency use.
  • One requirement of such switching elements is that no hot gas, particles, debris or plasma escape from them.
  • switching elements should ensure the insulation resistance after separation.
  • switching elements with a contact tube that conducts the current and a separation area in the form of a hollow cylinder are used, the hollow cylinder being completely torn, melted or broken open along its cross-sectional area to separate the circuit , and both ends of the hollow cylinder are mechanically removed from each other.
  • an activatable drive is often used, which is located in the hollow space of the hollow cylinder.
  • interruption switching elements usually contain a sabot which is used to move the separated ends of the separating area away from one another. The sabot must compress a compression area of the contact tube.
  • the compression area is also often tubular or hollow-cylindrical and must be able to fold well during compression. It was found, however, that with the rapid movement of the sabot and the compression of the compression area, it often splinters and the housing can make inadmissible electrical contact; the insulation of the already separated connecting element can be bridged here.
  • the invention is based on the object of providing an interruption switching element, in particular for interrupting high direct currents at high voltages, in which the material of the compression area is prevented from splintering during the transition from the control position to the disconnected position, so that no splinters can can short-circuit already separated and then electrically insulated from the housing contact of the assembly to the housing.
  • the present invention relates to an electrical interrupt switching element which is particularly suitable for interrupting high currents at high voltages. It has a housing which engages around a contact unit defining the current path through the interrupting switching element.
  • the contact unit has a first and second connection contact, a separation area and a compression area.
  • the contact unit is designed in such a way that a current can be fed to it via the first connection contact and removed from it via the second connection contact, or vice versa.
  • the contact unit has a sabot or is connected to a sabot.
  • the sabot is designed such that it can be moved from an initial position to an end position by applying pressure, the separation area being separated in the end position of the sabot and an isolation distance being achieved between the first and second connection contacts.
  • the compression area is designed in such a way that it is compressed when the sabot moves from the starting position into the end position.
  • the interruption switching element according to the invention is characterized in that the upsetting area is designed as a tubular or rod-shaped element, the axial direction of extent of which runs along an axis X, the tubular or rod-shaped element having one or more tapering in its cross-sectional area along the axis X, with the cross-sectional area perpendicular to the X axis.
  • the one or more tapers unlike in the case of a constant cross-sectional area along the X axis, during the transition from the control position to the disconnected position, splinters of the compression area can be largely avoided, so that the already separated contact of the interruption switching element is not electrically contacted towards the housing can. As a result, no larger parts are torn out of the compression area, but rather the compression area is folded up without the formation of harmful splinters.
  • the tubular or rod-shaped element merges at its two opposite end regions into flanges which extend in the direction of the housing and perpendicular to the X axis.
  • the purpose of these flanges is that a force can be exerted on the upsetting area from the sabot in the direction of the axis X, i.e. the compression area can be compressed.
  • the cross-sectional area of the rod-shaped or tubular element can have any shape, for example circular, elliptical, any circular without or with one or more corners, triangular, square, pentagonal, hexagonal or polygonal, a circular cross-sectional area being preferred. If it is a tubular element, then one speaks of a circular cross-sectional area rather than a circular cross-sectional area.
  • a tapering of the cross-sectional area is understood here to mean that the cross-sectional area is smaller in a region of the compression region than in the adjoining regions (in the direction of the axis X).
  • the compression region has a region of minimal cross-sectional area, which preferably increases in the direction of the two end regions of the compression region.
  • the increase in the cross-sectional area can be continuous or discontinuous, that is to say for example step-shaped, in the axial extent of the rod-shaped or tubular element, a continuous increase being preferred.
  • the continuous increase can be linear or progressive. It is preferred according to the invention that the cross-sectional area increases conically in the direction of the end regions of the rod-shaped or tubular element.
  • the rod-shaped or tubular element is designed such that it has a cross-sectional area of the same shape (with a varying size of the area) in each plane perpendicular to the axis X.
  • the increase in the cross-sectional area in the two directions towards the end regions of the rod-shaped or tubular element can be different or the same, ie mirror-symmetrical, the mirror plane being arranged perpendicular to the X axis in the area of the minimum cross-sectional area. It is also preferred that the cross-sectional transitions to the respective end regions of the rod-shaped or tubular element are radial run, ie are provided with certain radii in order to avoid excessive notch stresses that could undesirably break or break the rod-shaped or tubular element at these points, especially in the case of mechanical loads or vibrations of the assembly or the connecting element.
  • the upsetting area has several tapers, preferably so that the area of the minimum cross-sectional area periodically alternates with areas of maximum cross-sectional area.
  • the upsetting area on the surface can be zigzag-shaped, step-shaped or in the form of an accordion. The latter is preferred if the compression area is designed as a tubular element.
  • the area of the minimum cross-sectional area of the rod-shaped or tubular element can be designed as an area with a constant cross-sectional area. It is preferred here that the cross-sectional transitions run radially from the area with the minimum cross-sectional area to the areas in which the cross-sectional area increases, i.e. are provided with certain radii. In one embodiment, such a region with constant cross-sectional area can also be omitted, i. E. in the area of the minimum cross-sectional area, the areas in which the cross-sectional area increases meet, likewise preferably with a radial cross-sectional transition.
  • the interruption switching element according to the invention has at least one chamber which is at least partially delimited by the isolating area.
  • the at least one chamber is preferably filled with an extinguishing agent, so that the separation area is in contact with the extinguishing agent.
  • the at least one chamber is preferably located within a cavity of the separating area, which is preferably designed as a tubular element, ie the at least one chamber is enclosed by the separating area.
  • the interrupt switching element according to the invention can have a further chamber which adjoins the outer region of the tubular element of the separating region. In other words, the tubular element delimits the at least one chamber from the from another chamber.
  • the outer periphery of the further chamber is preferably delimited by the housing of the interruption switching element.
  • the further chamber is preferably also filled with an extinguishing agent.
  • the filling of the cavity of the tubular element separating area can, however, also be omitted, in this case only the further chamber outside the tubular connecting element is filled with an extinguishing agent.
  • the extinguishing agent can also be completely omitted, here the enclosed air is then sufficient for the separation process.
  • the extinguishing agent can be a solid, powdery or a liquid medium.
  • the extinguishing agent is preferably a vaporizable or gasifiable medium (e.g. boric acid; under the influence of the arc, this powder changes directly from the powdery phase into gas, where it absorbs energy and thus depletes the arc).
  • the extinguishing agent is preferably a liquid medium which, when the boiling or evaporation temperature is reached, changes completely or partially into a gaseous state.
  • the extinguishing agent also has good electrical insulating properties so that the arc can be extinguished after the two separated parts of the separation area have been sufficiently removed and there is then sufficient insulation between the separated contacts against a current flow that is then undesirable here.
  • the extinguishing agent is preferably an oil with or without a thickener, for example silicone oil, or a silane or polysiloxane, for example hexasilane or pentasilane, with as little as possible or, even better, without a carbon atom content.
  • the sabot has the task of separating the two separate parts of the separating area from one another by applying pressure to perform a mechanical movement that removes part of the separated separating area from the other part of the separated separating area. In this way, a safety distance is established between the two separate parts of the separation area.
  • the tripping of the interruption switch according to the invention i. the process of transition from the control position to the disconnected position can be passive or active.
  • the interruption switching element comprises an activatable material.
  • the activatable material is preferably arranged in such a way that when the pyrotechnic material is ignited, a gas pressure or shock wave generated by the activatable material is applied to the separating area, so that the separating area is torn, depressed or separated, the sabot is moved and the compression area is compressed.
  • the sabot is preferably designed in such a way that, when the activatable material is ignited, a gas pressure or shock wave generated thereby is applied to it in such a way that the sabot in the housing moves in one direction of movement from the starting position to the end position and the separation area is torn open. pushed in or separated.
  • the activatable material can be a pyrotechnic material that has a detonating or deflagrating effect.
  • the pyrotechnic material is preferably present in the interruption switching element according to the invention in a so-called mini-tonator, or an igniter pill, but can also be introduced in a different form.
  • the interruption switching element according to the invention is to be triggered passively, i.e. without an activatable material for the first severing of the separating area
  • the separating area, the sabot and the extinguishing agent are designed in such a way that the separating area is caused by the supplied current when a threshold current strength is exceeded can be separated into at least two parts by heating at or above the melting point of the material of the connecting element, with an arc arising between the two parts of the separation area evaporating the extinguishing agent, so that a gas pressure is created which acts on the sabot, the sabot being moved and the compression area being compressed.
  • the separation area can also have one or more predetermined breaking points, which can be in the form of a constriction, notch, groove or hole.
  • the predetermined breaking point is preferably in the form of a bore through the wall of the tubular element of the separating region. In this way, the bore connects the at least one chamber with the further chamber. In this way it is easier to fill an extinguishing agent into the at least one chamber within the tubular element during the production of the interruption switching element according to the invention.
  • the design of the upsetting area according to the invention is particularly advantageous or of great importance when using materials for the upsetting area which are not as ductile as the E-copper usually used here.
  • materials for the upsetting area which are not as ductile as the E-copper usually used here.
  • a hard aluminum must be used as the material for the connecting element, which would break up immediately into many small splinters during the folding process, even if the connecting element was soft annealed after its manufacture.
  • the upsetting area is designed as a tubular element.
  • the cavity inside the tubular element is referred to herein as yet another chamber.
  • the further chamber of the compression area can also be completely filled with an extinguishing agent. It is preferred that there is a connection in the form of a channel between the still further chamber and the at least one chamber. The movement of the sabot and / or the upsetting process of the upsetting area reduces the volume of the still further chamber in such a way that the extinguishing agent is injected through the channel between the at least two parts of the separating area.
  • the extinguishing agent can be pressed from the still further chamber via the channel into the at least one chamber during the upsetting process and thus further effectively prevents or cools any arc that may still be at the separation area.
  • the extinguishing agent that may already have partially decomposed in the at least one chamber is diluted by the newly flowing extinguishing agent and thus the insulating properties of the "stressed" extinguishing agent are also improved.
  • the illustrated embodiment of an interrupter switching element 1 comprises a housing 2 in which a contact unit 3 is arranged, which extends through the entire housing 2 and comprises the connection contacts 4 and 5, the separation area 6, the compression area 12 and the flanges 13 and 14 .
  • the housing 2 is designed in such a way that it withstands a pressure generated within the housing 2, which is generated, for example, in the event of a pyrotechnical triggering of the interruption switching element 1, without the risk of damage or even bursting.
  • the housing 2 can in particular consist of a suitable material, preferably steel.
  • the contact unit 3 is in the illustrated embodiment as a through the sabot 9 is formed in the compression area 12 pressable switching tube, so that it is formed as a tube in the separating 6 and compression area 12.
  • the contact unit 3 has a first connection contact 4.
  • the first connection contact 4 is adjoined by a radially outwardly extending flange 14, which is supported on an annular insulator element made of an insulating material, for example a plastic, in such a way that that the contact unit 3 cannot be moved out of the housing 2 in the axial direction.
  • the contact unit 3 has an upsetting area 12 adjoining the flange in the axis of the contact unit 3.
  • the wall thickness of the contact unit 3 in the compression area 12, which has a predetermined axial extent, is selected and matched to the material that when the interruption switching element 1 is triggered as a result of a plastic deformation of the contact unit 3 in the compression area 12, the compression area 12 is shortened in the axial direction Direction by a predetermined distance results.
  • a flange 13 adjoins the upsetting region 12, on which a sabot 9 is seated in the illustrated embodiment.
  • the sabot 9 is designed as an electrically insulating element, for example a suitable plastic, preferably made of ceramic. This engages around the contact unit 3 in such a way that an insulating area of the sabot 9 engages between the outer circumference of the flange 13 and the inner wall of the housing 2. If pressure acts on the surface of the sabot 9, a force F is generated which compresses the compression area 12 of the contact unit 3 via the flange 13.
  • the sabot 9 can be selected so that its outer diameter essentially corresponds to the inner diameter of the housing 2, so that an axial guidance of the flange 13 and thus also an axially guided compression movement is achieved during the switching process.
  • the noses of the insulator element and the sabot 9, which are close to the housing 2 fully overlap one another, so that the upsetting area 12, which is pushed together in a meandering shape after the triggering and the upsetting process, is fully enclosed by electrically insulating materials.
  • a separating area 6 adjoins the sabot 9 or the flange 13 of the contact unit 3.
  • the second connection contact 5 then connects on this side of the contact unit 3.
  • the sabot 9 is pushed onto the contact unit 3 from the side of the connection contact 5 when the interruption switching element 1 is installed. This is divided for this purpose (not shown). If the second connection contact 5 is not divided or if it is in one piece the same as the contact unit 3, as shown, the sabot 9 must either be molded on or made in several parts in order to be able to assemble it.
  • an activatable material 10 can be provided, here often also housed in a mini-tonator or an ignition screw (drive). Electrical connection lines for the drive can be led to the outside through an opening in the interior of the contact unit 3.
  • the drive is preferably provided in a chamber 7 within the tubular element of the separating region 6. Another chamber 8 is located between the outer wall of a separating area 6 and the housing 2.
  • the separation area 6 is dimensioned so that it at least partially tears open by the generated gas pressure or the generated shock wave of a drive, but preferably tears completely, so that the pressure or the shock wave also flows out of the chamber 7 into the outer annular space, which is preferably designed as a surrounding annular space Chamber 8 can expand.
  • the chambers 7 and 8 are connected to one another in this way to form a volume.
  • the internal pressure required for upsetting the contact unit 3 can also be generated in such a way that, at a certain threshold current strength, the separating area 6 melts and an arc forms between them, which causes an extinguishing agent located in the chambers 7 and / or 8 evaporates.
  • the wall of the contact unit 3 in the separating area 6 can also have one or more openings or bores and / or grooves (not shown in FIG Fig. 1 ). It must be ensured here that the material of the separating region 6 separates the operating current well, that is to say, taking into account heat dissipation, does not become too hot in order not to allow the material to age too quickly or too strongly.
  • a pressure or even a shock wave is generated on the side of the sabot 9 facing away from the upsetting region 12, as a result of which the sabot 9 is subjected to a corresponding axial force.
  • This force is selected by suitable dimensioning of the activatable material 10 such that the contact unit 3 is plastically deformed or pressed in in the compression region 12, but not torn and then the sabot 9 is moved in the direction of the first connection contact 4.
  • the activatable material 10 is dimensioned in such a way that after the separation area 6 has been broken open or pressed in, the movement of the sabot 9 moves the two separating halves sufficiently far apart, in cooperation with the evaporation of an extinguishing agent then even into an end position.
  • the separating area 6 is at least partially torn open or pressed in, preferably completely torn open. If the tearing or pushing in does not take place before the start of the axial movement of the sabot 9 over the complete circumference of the separating area 6, a remainder of the separating area 6, which still causes electrical contact, is completely torn open by the axial movement of the sabot 9, reinforced by the very rapid heating of the then only small residual cross-section of the conductor due to the high electrical current flowing here.
  • the interruption switch 1 after Fig. 1 is structured in the same way as that in Fig. 1 Interrupting circuit shown in the DE 10 2017 123 021 A1 , with the difference according to the invention that the upsetting area 12 does not represent a tubular element with a consistently identical wall thickness, but that the tubular element is in an area between the flange-side end areas has several tapers in its cross-sectional diameter.
