Definitions

  • the invention relates to electrical short-circuiting devices, transistor devices with short-circuiting devices and to converters which are equipped with submodules and short-circuiting devices.
  • IGBT modules that is to say transistor devices based on bipolar transistors with an insulated gate electrode, are usually — with regard to the construction and connection technology — designed with bond wires and screw contacts.
  • IGBT module failure particularly in the event of a shutdown failure, conventional IGBT modules are not reliably electrically conductive. This failure mechanism is particularly problematic in the case of a series connection of IGBTs and in the case of use with converters, in particular multilevel converters. If, for example, the aforementioned bond wires are detached in the event of a fault and thus an arc is ignited, considerable collateral damage can occur, particularly when used in converters.
  • the international patent application WO 2011/107363 A1 discloses an electrical short-circuiting device with the features according to the preamble of claim 1.
  • the short-circuiting device has an electrical contact arrangement with a first and second contact, which are separated from one another by an air gap.
  • the known short-circuiting device also has a moving contact piece which is separated from the second contact in a disconnected position and connects the first and second contacts to one another in a contact position.
  • the known short-circuiting device is equipped with an electrically triggerable drive device in the form of a pyrotechnic drive, which can move the moving contact piece from the disconnected position to the contact position.
  • the US 2003/0231443 A1 discloses a bypass switch in which a conductive plug is pushed between the two contacts by means of a drive. The plug in turn pushes an insulating element, which is arranged in a disconnected position of the bridging switch between the contacts.
  • the invention is based on the object of specifying an electrical short-circuiting device which can be used particularly universally in terms of circuit technology.
  • the short-circuiting device has an electrically triggerable drive device, which is electrically isolated from the first and second contacts by means of an insulating device consisting of insulating material, in particular solid insulation material, or at least having insulating material.
  • a major advantage of the electrical isolation of the electrically triggerable drive unit provided according to the invention consists in the fact that the short-circuiting device can also be used in electrical circuit arrangements in which the electrical contacts to be short-circuited are subjected to different potentials over time, as is the case, for example, with four-quadrant actuators (also referred to as full bridges).
  • the short-circuiting device according to the invention is particularly well suited to be used as a switchable short-circuit element in converters or their components, such as, for example, transformer devices.
  • Another significant advantage of the short-circuiting device according to the invention is that the potential separation can be achieved particularly inexpensively by means of the insulating material.
  • the short-circuiting device for potential isolation has an at least two-part insulating device which comprises a first fixed insulating element and a second insulating element which is fastened to the moving contact piece and moved with it.
  • the second insulating element By attaching the second insulating element to the moving contact piece, the potential separation is always ensured regardless of the position of the moving contact piece.
  • first insulating element is at least partially sleeve-shaped and the second insulating element projects at least partially into the first insulating element.
  • the second insulating element is preferably arranged in sections coaxially inside the first insulating element.
  • the second insulating element preferably forms a telescopic structure with the first insulating element, the length of which increases when the moving contact piece is moved after the drive device has been triggered.
  • the second insulating element and the first insulating element are mechanically separated from one another by an intermediate sleeve.
  • an intermediate sleeve consists of a conductive material.
  • the first insulating element, the second insulating element and / or the intermediate sleeve are preferably rotationally symmetrical.
  • the first and second insulating elements - together alone or together with a third or further insulating element and / or with an intermediate sleeve - form a potential-separated interior into which the drive device according to one Activation feeds a gas to drive the moving contact, and whose internal volume depends on the position of the second insulating element and grows with the movement of the moving contact.
  • a third insulating element is provided, it is particularly advantageous if it is formed by an inner ring made of electrically insulating material.
  • Such an inner ring preferably carries the drive device and is preferably held by the first insulating element or an intermediate sleeve arranged in the first insulating element.
  • the inner ring closes the above-mentioned electrically isolated interior preferably on the outside on one side on which electrical connection contacts for the drive device are led out.
  • the first fixed insulating element is preferably attached directly or indirectly to the first contact with a view to simple assembly.
  • the drive device is preferably a pyrotechnic drive device.
  • the invention also relates to a transistor device, in particular in the form of a bipolar transistor with an insulated gate electrode.
  • such a transistor device is provided with a short-circuiting device as described above.
  • the invention also relates to a converter, in particular a multilevel converter, with a plurality of submodules.
  • the submodules can be designed, for example, as half-bridge or full-bridge circuits and can be connected to one another to form at least one series circuit.
  • the invention provides that the converter has at least one short-circuiting device as described above and / or at least one transistor device as described above.
  • the short-circuiting device is preferably connected in parallel to one of the submodules or a component of one of the submodules.
  • the short-circuiting device is connected in parallel to a capacitor of one of the sub-modules or is connected in parallel via at least one transistor or at least one diode to a capacitor of one of the sub-modules and, after the moving contact piece has transitioned from the disconnected position to the contact position, the capacitor of the submodule shorts.
  • All submodules of the converter are particularly preferably equipped with a short-circuiting device, as has been described above.
  • the short-circuiting device is connected in parallel to a capacitor of one of the sub-modules via at least one transistor or via at least one diode and short-circuits the capacitor of the sub-module after the moving contact piece has transitioned from the disconnected position to the contact position.
  • the Figure 1 shows a short-circuiting device 10 which has a first contact 20 and a second contact 30 spaced apart from the first contact 20.
  • the two contacts 20 and 30 are mechanically connected to one another by a spacer 40, which consists of electrically insulating material.
  • the short-circuiting device 10 has a moving contact piece 50, which is shown in FIG Figure 1 is in its disconnected position and leaves the two contacts 20 and 30 electrically separated.
  • the short-circuiting device 10 also has a pyrotechnic drive device 60, which moves the moving contact piece 50 along the thrust direction S in the Figure 1 can move from left to right or in the direction of the second contact 30.
  • the pyrotechnic drive device 60 is electrically isolated from the first contact 20 and from the second contact 30; an insulation device for potential isolation is for reasons of clarity in the Figure 1 not shown in detail.
  • the Figure 2 shows the short-circuiting device 10 according to Figure 1 after the pyrotechnic drive device 60 has been ignited by means of an ignition signal ZS and gas G of the pyrotechnic drive device 60 has pushed the moving contact piece 50 along the thrust direction S to the right in the direction of the second contact 30.
  • the position of the moving contact piece 50 shown electrically connects the first contact 20 to the second contact 30 and thus forms an electrical short circuit between the two contacts 20 and 30.
  • FIG. 3 shows an exemplary embodiment of an insulating device 100 which is used to isolate the potential of the pyrotechnic drive device 60 in the short-circuiting device 10 according to FIGS Figures 1 and 2 can be used.
  • FIG. 3 shows the disconnected position of the moving contact piece 50 of the short-circuiting device 10 in the left half of the figure and the contact position of the moving contact piece 50 in the right half of the picture; the two representations or halves of the picture are separated from one another by the central axis M of the short-circuiting device 10.
  • the insulation device 100 has a first, fixed insulation element 110, a second insulation element 120 connected to the moving contact piece 50, a third insulation element in the form of an inner ring 130, and an intermediate sleeve 150, which is spatially between the first fixed insulation element 110 and the second insulation element 120 is arranged.
  • the second insulating element 120 Since the second insulating element 120 is mechanically firmly connected to the moving contact piece 50, when the moving contact piece 50 moves, it becomes different from that in the left half of the figure separated position shown in the contact position shown in the right half of the figure moves with it, whereas the first insulating element 110 does not change its location due to the fixed mounting on the first contact 20.
  • the telescopic structure formed by the first and second insulating elements 110 and 120 is thus lengthened by the movement of the second insulating element 120.
  • the second insulating element 120 is composed of two electrically insulating and interconnected insulating sections 121 and 122.
  • the inner ring 130 serves to receive or to carry the pyrotechnic drive device 60.
  • the first insulating element 110, the second insulating element 120, the inner ring 130 and the intermediate sleeve 150 are rotationally symmetrical.
  • the second insulating element 120 is preferably mounted coaxially both inside the first insulating element 110 and coaxially inside the intermediate sleeve 150.
  • the three insulating elements 110, 120 and 130 as well as the intermediate sleeve 150 together form a potential-separated interior 160 within the insulating device 100, into which the pyrotechnic drive device 60 after applying an ignition signal ZS (cf. Figure 2 ) feeds the gas G.
  • ZS ignition signal
  • the second insulating element 120 is shown in Figure 3 pushed upwards, whereby the moving contact piece 50 connected to the second insulating element 120 is also pushed upward and its contact position (cf. Figure 2 ) can reach.
  • the isolation or electrical separation of the pyrotechnic drive device 60 from the first contact 20 takes place in the insulation device 100 according to FIG Figure 3 through the three insulating elements 110, 120 and 130.
  • the intermediate sleeve 150 is preferably used for electromagnetic shielding of the pyrotechnic drive device 60 located inside and is therefore preferably made of conductive material.
  • the short-circuiting device 10 is preferably used for short-circuiting transistor devices, in particular bipolar transistors with an insulated gate electrode, and / or for short-circuiting submodules of converters, in particular multilevel converters.
