Definitions
- the invention relates to a disconnector unit for interrupting an electrical line with a contact arrangement and an electromagnetic drive means.
- the contact arrangement has a first and a second fixed contact and a guided moving contact, wherein the terms contact and contact piece in this context are understood to be synonymous.
- the electromagnetic drive means is arranged to move the moving contact.
- the disconnecting unit can assume a first and a second state, wherein in the first state there is no electrical connection between the first and the second fixed contact, while in the second state the moving contact electrically connects the two fixed contacts to one another.
- the separator unit can be moved by moving the moving contact from the second to the first state.
- Switching systems with the separator unit of this type are already known and are generally used in medium and high voltage engineering for the switching of currents, in particular short-circuit currents. They are used in particular in networks of the electrical power supply, where short circuit currents can lead to a separation of the energy flow to the consumer and on the other hand to high mechanical loads of current-carrying network components.
- Häfner et al. describe in their article "Proactive Hybrid HVDC Breakers - A Key Innovation for Reliable HVDC Grids", Integrating Super Grids and Microgrids International Symposium, 2011, a hybrid DC switching system in which the main path is a mechanical circuit breaker and an electronic circuit breaker. includes niche auxiliary switch.
- a power switching unit is arranged, which is a series circuit of electronic
- the circuit breaker Has switches. If the circuit breaker has reached the necessary dielectric strength, the short circuit current can be interrupted by the circuit breaker unit. The released energy is dissipated in non-linear resistors of the circuit breaker.
- the moving contact of the contact arrangement is in this case realized as a massive copper disk, which is guided movably perpendicular to the current flow direction.
- the electromagnetic drive means comprises a Thomson coil arranged coaxially with the copper disk. Utilizing the Thomson effect, the moving contact can be moved so that the interrupter unit is transferred from the second to the first state.
- the separator unit according to the invention is more compact than the previously known separator units. Further advantages are: a very short reaction time, since the electromagnetic field exerts its effect directly on the moving contact; very short movement times, because no additional mechanical parts have to be moved; easy control of the movement of the guided moving contact, including the acceleration and deceleration by the magnetic field; Achieving repetition rates with very short times between the two states of the separator unit; Avoidance of additional masses in the arrangement.
- the electromagnetic drive for example, in contrast to the explosion drive can be actuated as often as desired.
- the electromagnetic drive does not require any insulation between high-voltage-carrying parts and a drive stator.
- the recess of the second fixed contact is preferably set up for guiding the moving contact.
- the moving contact in the second state of the disconnector unit makes the electrical connection between the two fixed contacts in that it contacts the two fixed contacts simultaneously.
- the separating unit is in the first state transfer, so the contact between the moving contact and the first fixed contact is disconnected.
- the contact between the moving contact and the second fixed contact preferably also exists when the disconnecting unit is in the first state.
- the first fixed contact also has a recess.
- the moving contact engages at least partially in the recess of the first fixed contact when the disconnector unit is in the second state.
- the moving contact engages both in the recess of the first fixed contact and in the recess of the second fixed contact when the
- Separator unit is in the second state.
- this can be solved, for example, from the recess in the first fixed contact to engage in the recess corresponding to deeper in the second fixed contact.
- the recesses are preferably to be designed such that the engagement of the moving contact in the respective recess provides a secure electrical connection between the respective fixed contact and the moving contact.
- the moving contact is braked by suitable measures after its acceleration, in order to avoid a so-called "bouncing", that is, a - possibly multiple - rearward displacement of the moving contact.
- This rearward displacement can lead to a separate electrical connection between the two festival clocks can be restored accidentally.
- the recesses are to suitably be dimensioned such that in each case a portion of the recess can be used as a damping chamber.
- the recess of the second fixed contact is arranged for longitudinally movable guidance of the moving contact. This simplifies the geometry of the arrangement and eliminates any additional guide means for the movement of the moving contact.
- the moving contact is movable within the recess along a longitudinal axis, wherein it is inserted deeper into the recess or led out of the recess.
- the moving contact is a pin-shaped pin contact.
- the pin contact may, for example, have an approximately circular cylindrical geometry. It is also conceivable that the recess in the second fixed contact is designed complementary to the shape of the pin contact, so that the recess for guiding the pin contact is particularly well suited.
- the moving contact comprises a ferromagnetic core and an at least partially enclosing and electrically conductive outer shell.
- the outer shell has a high conductivity.
- the outer shell can be made of copper or aluminum.
- the conductivity of the outer shell is preferably more than 10 7 A / Vm. It is also conceivable that the core is a permanent magnet.
- the weight of the moving contact is between 1 g and 10 kg, a weight between 10 g and 1 kg is particularly suitable.
- the first and the second fixed contact are formed as electrically conductive tulip contacts.
- the tulip-shaped fixed contacts for example, particularly well with the pin-shaped
- the contact arrangement has a circular cylindrical geometry.
- the moving contact and the two fixed contacts are circular-cylindrical.
- the moving contact is displaceable along the cylinder axis.
- the recess of the second fixed contact can be designed such that the moving contact can be guided by means of the recess along the cylinder axis.
- the diameter of the moving contact is not larger than an inner diameter of the recess.
- the separator unit may further comprise a housing.
- the housing is filled with an insulating gas.
- the housing is gas-tight and designed such that the contact arrangement in the contacting region between the first fixed contact and the moving contact and between the moving contact and the second fixed contact is enveloped by the insulating gas.
- the insulating gas should have the highest possible dielectric strength. Therefore, in particular, the gas SF 6 is suitable as an insulating gas. However, it is also conceivable to use another suitable gas or gas mixture, such as a of N 2 and SF 6, wherein the weight percentage of SF 6 is between 10% and 50% may be mixed. It is advantageous if the insulating gas can fulfill the function of a quenching gas to avoid arcing. However, since the disconnecting unit essentially opens only small currents when opening the contacts in the event of a short circuit, this function of the insulating gas is not of decisive importance for the present invention.
- the insulating gas is in the housing under a pressure of 1 bar to 10 bar, more preferably from 7 to 9 bar.
- the electromagnetic drive means may comprise a coil.
- the coil is preferably arranged concentrically around the moving contact.
- the coil is disposed within the housing.

- the magnetic field of the coil and the magnetic field of the moving contact have the same polarity (reluctance effect).
- the coil is arranged on the second fixed contact, the moving contact can be moved away from the first fixed contact in the direction of the second fixed contact.
- the disconnector unit can be transferred from the second to the first state.
- the switching time in this case depends on the inductance of the coil.
- the coil current is to be adapted to the force to be applied and may be, for example, in the range between 10 A and 500 A, preferably between 20 A and 200 A.
- both effects for moving the moving contact can be combined by suitable control of the current flow through the coils.
- the separator unit having a combination of the features described above may be incorporated into a DC hybrid switching system for Be integrated medium and high voltage systems.
- the hybrid switching system is preferably to be used at voltages in the range of more than 1 kV, preferably more than 70 kV.
- the hybrid switching system comprises an operating current leading, the mechanical isolator unit comprising the main path and a parallel, an electronic circuit breaker comprehensive bypass path.
- the hybrid switching system can also auxiliary switches and other elements and other paths, for example, parallel to the
- the separator unit may have one or a combination of several features described above.
- the disconnector unit according to the invention can be used in a direct voltage network (DC network) or a multi-terminal system comprising a plurality of converter systems.
- DC network direct voltage network
- multi-terminal system it is often necessary according to the prior art to disconnect the entire system from the grid in the event of a fault, for example a short circuit, whereby the converter installations must be shut down. Only after the fault has been corrected can the system be restarted and put into operation.
- the disconnector unit can be used to disconnect a connection between converter systems of the system in the event of a fault, in order to disconnect the part of the system which is affected by the error. Due to the fast switching time of the separator unit, a breakdown of the entire system can be prevented.
- At least one of the converter systems may, for example, be a self-commutated high-voltage direct current transmission system (HVDC system). It may, for example, comprise a multi-stage inverter having phase modules with submodules connected in series, the two-pole submodules being designed as full-bridge circuits or half-bridge circuits.
- HVDC system can switch the connection to be disconnected without current and voltage, so that the disconnector unit can then disconnect the connection.
