Definitions

  • the invention relates to a switching device for conducting and isolating electrical currents, in particular a hybrid switching arrangement for conducting and isolating high DC currents and low-frequency AC currents, and a switching device with such a switching device.
  • the formation of an undesired arc can be provoked, for example, if an electrical breakdown occurs between the not yet fully opened mechanical switching contacts immediately after the power semiconductor has switched off. This can have been caused, for example, by welding of the contacts during a previous switch-on process, which as a result leads to a time-delayed opening process due to the welding being broken by the switching drive.
  • a voltage breakdown with subsequent arcing can also occur if the topography of the originally smooth contact surfaces has changed significantly over time as a result of numerous switching loads, e.g. in the case of contactors. If the switching contacts are not yet completely open, a voltage breakdown with subsequent arcing can occur due to local field overshoots.
  • a gradual change in the contact topography can be brought about, for example, by switch-on bounce processes. Such bouncing processes result in the formation of short-term, low-energy arcs between the minimally opened contacts, which lead to minor local melting of the contact surfaces in the area of the base points of the arcs, which gradually change the contact surfaces overall.
  • Such repeated formation of an arc results in a gradual material displacement of the contact material, due to the different mobility of positive and negative charge carriers.
  • Voltage conditioning is mainly used for vacuum interrupters in the medium-voltage range.
  • the method of voltage conditioning consists of applying a voltage between the open switch contacts, preferably an AC voltage in the range above 1000 volts, and gradually increasing this until voltage breakdown occurs between the contacts. Since this occurs primarily at points where local electric field increases occur due to micro-tips, these are melted or vaporized at certain points due to the energy content of the charge carrier packets penetrating through and are thereby removed, which results in a smoothing of the contact surfaces and thus an increase in the dielectric strength of the opened contacts causes.
  • a device for voltage and current conditioning of vacuum interrupters is, for example, in the German Offenlegungsschrift DE 199 42 971 A1 described.
  • the method of current conditioning is described in detail as a manufacturing measure to improve the properties of vacuum interrupters.
  • the object of the present invention is now to propose a switching device for conducting and isolating electrical currents, in particular an improved hybrid switching arrangement for conducting and isolating high DC currents and low-frequency AC currents, and an improved switching device with such a switching device.
  • the present invention proposes a hybrid switch such as that described at the outset and from the German Offenlegungsschrift DE 10 2013 114 259 A1 to modify known switches in such a way that switching operations of the mechanical contact arrangement are detected and, depending thereon, to control the switching on and off of a semiconductor switch during a switching operation of a mechanical contact arrangement in such a way that contact surfaces of contacts of the mechanical contact arrangement can be conditioned.
  • the switching on and off of the semiconductor switch can then be controlled in such a way, for example, after a specific number of detected switching operations or when a specific cumulative switching power is reached that specifically one or several arcs occur when opening the contacts of the mechanical contact arrangement, which can smooth the contact surfaces.
  • the invention can therefore be used to implement a recurring, in particular periodic, current conditioning by means of control technology, as a result of which the functional reliability of the mechanical contact arrangement can be improved with regard to achieving a long electrical service life.
  • One embodiment of the invention now relates to a switching device for conducting and isolating electrical currents with a mechanical contact arrangement, a semiconductor switch which is connected in parallel with the mechanical contact arrangement, and switching electronics which are used to switch the semiconductor switch on and off during a switching operation of the mechanical contact arrangement for Commutation of an electric current is formed by the mechanical contact arrangement on the semiconductor switch.
  • the switching electronics are configured to detect switching operations of the mechanical contact arrangement and, depending on this, to control the switching on and off of the semiconductor switch during a switching operation of the mechanical contact arrangement in such a way that contact surfaces of contacts of the mechanical contact arrangement can be conditioned. This enables the implementation of, in particular, periodic current conditioning in the switching device.
  • the switching electronics can be configured to count the number of switching operations after an initialization in order to detect the switching operations and, when a predetermined number of switching operations is reached in a subsequent switching operation, to turn on the semiconductor switch with a predetermined blocking time t1 after the contacts of the mechanical contact arrangement have opened.
  • periodic current conditioning can be implemented, for example, by switching on the semiconductor switch with a delay after the contacts of the mechanical contact arrangement have opened after a certain number of switching operations, such that one or more arcs occur between the opening contacts, which then continue until the end of the blocking time t1 and can cause a smoothing of the contact surfaces.
  • the switching electronics can be configured to record the switching operations, to record the switching capacity for each individual switching operation after an initialization and, when a specified cumulative switching power is reached in a subsequent switching operation, to delay the semiconductor switch by a specified blocking time t1 after opening the contacts of the mechanical to switch on the contact arrangement.
  • the specified blocking time t1 can be selected depending on parameters of the switching device in such a way that one or more arcs can form between the contact surfaces of the contacts of the mechanical contact arrangement that open during the blocking time, so that due to the current strength of each arc at the base points of the arcs on the contact surfaces Material melting can occur.
  • the specified blocking time t1 can depend on the current intensity to be switched, the switching voltage, the material of the contact surfaces, the opening time of the contacts, the distance that can be reached between the contacts during the specified blocking time, a vacuum in which the mechanical contact arrangement is possibly located and other parameters be selected, which can have an influence on the formation of arcs when opening the contacts of the mechanical contact arrangement.
  • the switching device can have a further mechanical contact arrangement and both mechanical contact arrangements can be connected in series.
  • Such a double-break switching device is particularly well suited for the use of the invention, since this type of switching device is primarily used for switching high direct currents in which the probability of the occurrence of standing arcs is high and current conditioning is therefore required from time to time to smooth the Contact surfaces can be very helpful in reducing the likelihood of standing arcs.
  • the switching device can have an auxiliary coil which is galvanically isolated from the circuit of a switching drive for moving contacts of the mechanical contact arrangement and is electromagnetically coupled to a coil of the switching drive in such a way that when the voltage supply to the Switching drive a voltage is generated, which is fed to the switching electronics to supply.
  • the switching electronics can be operated without an external electrical energy supply; in particular, no separate connection for the energy supply or, in general, an energy supply that is independent of the circuit to be switched is required.
  • a current converter can be provided for detecting the current flow through the semiconductor switch and generating a corresponding signal that is fed to the switching electronics.
  • the signal can be evaluated by the switching electronics, for example, in order to record the exact commutation time of the current flow from the mechanical contact arrangement to the semiconductor switch, but also to record the duration of the current load on the semiconductor switch and to protect the semiconductor switch from excessive loading and possible destruction protect.
  • a further embodiment of the invention relates to a switching device with a switching device according to the invention and a switching drive for moving contacts of the first and second mechanical contact arrangement.
  • one embodiment of the invention relates to a method for controlling a semiconductor switch of a switching device for conducting and isolating electrical currents, which has a first mechanical contact arrangement, the semiconductor switch, which is connected in parallel to the first mechanical contact arrangement, and a second mechanical contact arrangement, which is in series is connected to the first mechanical contact arrangement, wherein in the method switching operations of the mechanical contact arrangement are detected and depending on this the switching on and off of the semiconductor switch during a switching operation of the mechanical contact arrangement is controlled in such a way that conditioning of contact surfaces of contacts of the mechanical contact arrangement can take place.
  • the method can be carried out by switching electronics designed to switch the semiconductor switch on and off.
  • the Switching electronics may be implemented by a processor and a memory storing a program configuring the processor to carry out a method according to the invention and as described herein.
  • FIG. 1 shows the block diagram of a switching device according to the invention for a 2-pole, polarity-independent switching device.
  • the connections of the switching device for the two poles are labeled L1, T1 and L2, T2 respectively.
  • This switching device In terms of circuitry, this largely corresponds to that in the German Offenlegungsschrift DE 10 2013 114 259 A1 described and therein in 1 shown device.
  • the inventive device described below differs from this known device in the switching electronics 50, which is designed for a special activation of the semiconductor switch 20, as will be explained in detail in the following description.
  • the switching electronics 50 can be implemented, for example, by a processor and a memory (in particular a microcontroller), with a program being stored in the memory that configures the processor to carry out method steps which, as explained below by way of example, the special control of the semiconductor switch 20 by the effect processor.
  • the program can be part of the firmware of a processor-controlled switching device, for example.
  • the switching device shown has a parallel connection of a first mechanical (extinguishing) contact arrangement 10 with a semiconductor switch 20 based on an anti-serial IGBT arrangement (power semiconductor), which is connected in series with a second mechanical contact arrangement 30 to ensure galvanic isolation.
  • the mechanical contact arrangements 10 and 30 can be designed as a bridge switching arrangement of an air switching device or arrangement.
  • the semiconductor switch 20 is switched on or off by the switching electronics 50, that is to say it is switched on or off.
  • the electronic switching system 50 is supplied with energy stored in the (magnetic drive) coil of the switching or magnetic drive of the switching device.
  • an auxiliary coil 40 is provided which is galvanically isolated from the circuit of the switching drive and which can generate a voltage for supplying the switching electronics 50 when the switching drive is switched off.
  • the auxiliary coil 40 can be wound around the drive coil, for example.
  • the switching electronics 50 can be supplied by an external electrical energy source (not shown), for example from a central energy source for the electrical units of a switch cabinet or via a bus system to which a number of switching devices are coupled, and the like.
  • the semiconductor switch 20 In the switched-on case, ie when the switching drive supplies the magnetic drive coil with a voltage and a current and the contacts of the first and second mechanical contact arrangements 10 and 30 are closed, the semiconductor switch 20 is blocked, since in this state there is no voltage from the auxiliary coil 40 is generated to supply the switching electronics 50 and the switching electronics 50 is therefore de-energized and the IGBTs of the semiconductor switch 20 can not drive.
  • the magnetic drive coil of the switching drive At the moment the voltage and current supply of the magnetic drive coil of the switching drive is switched on in order to close the contacts of the first and second mechanical contact arrangements 10 and 30, energy is stored in the magnetic drive coil.
  • the coil current induces a voltage in the auxiliary coil 40 electromagnetically coupled to the magnetic drive coil, which voltage activates the switching electronics 50 .
  • the voltage induced in the auxiliary coil 40 is sufficient, on the one hand, to supply the switching electronics 50 itself and, on the other hand, to build up the voltage required to drive the IGBTs.
  • the auxiliary coil 40 offers the advantage that the semiconductor switch can be driven even before the contacts of the first and second mechanical contact arrangements 10 and 30 are closed due to the mechanical inertia.
  • each switching operation is recorded and stored by the switching electronics. This can be done either as a pure counting process or by additionally recording the switching power for each individual switching process, e.g. with the help of suitable current and voltage sensors integrated in the hybrid switch.
  • the load current is switched off in the manner typical of hybrid switches, ie during the opening process of the mechanical switch contacts, the load current flows briefly via the semiconductor switch 20, where it is brought to zero within a few milliseconds.
  • the switch-off process of the following switching process or some other subsequent switching processes is then modified according to the invention in such a way that when the switching contacts open, the semiconductor switch 20 is not activated for a defined time interval of, for example, a few 10 milliseconds so that an arc burns between the switching contacts within this interval.
  • the semiconductor switch 20 is finally turned on, as a result of which it then takes over the load current in the usual way and leads it to zero within a very short time.
  • FIG. 2A - C The smoothing effect of the contact surfaces achieved with such a current conditioning is shown schematically in Figures 2A - C:
  • the in the Figures 2A-C The mechanical contact arrangement of a vacuum switch shown has a first electrode 100 and a second electrode 102 .
  • Each of the electrodes 100, 102 has a contact 104, 106, respectively, which each include a contact surface 108, 110, respectively, which are pressed together to contact one another.

  • the material removal point 112 and the material accumulation point 114 can, for example, by several switching processes and any local melting that occurs as a result may have arisen as described above.
  • Figure 2B shows the same contact arrangement in which vacuum arcs 116 are intentionally drawn after a defined number of switching operations when opening, in that a correspondingly dimensioned DC voltage is applied to the electrodes 100, 102 between the opened contacts 104 and 106 for a predetermined period of time.
  • the base points of the vacuum arcs 116 preferably form in this area, which results in a partial leveling of the surface inhomogeneities due to the arc work acting there, as shown in Figure 2C is shown.
  • the contact surfaces 108 and 110 have now been smoothed due to the current conditioning in that they now have a partially leveled material removal point 112' and a partially leveled material accumulation point 114'.
  • step S10 the switching electronics 50 are initialized; the energy supply required for this can be taken from the load circuit, for example, or it takes place inductively via the auxiliary coil 40, which is supplied by the freewheeling voltage of the magnetic drive coil when the switching device is switched off.
  • the electronic switching system 50 checks in step S12 whether a target number of switching operations for periodic current conditioning has been reached, in particular by reading out a stored number of switching operations from an internal non-volatile memory, which represents the number of switching operations carried out since the current conditioning was last carried out, and the number of switching operations read out with it compares the target switching number, which is specified electronically in particular, which depends on parameters of the switching device for a suitable current conditioning period can be selected, for example depending on the current load of the switching device.
  • step S12 If it is determined in step S12 that the target number of switching operations for a periodic current conditioning has been reached, the semiconductor switch 20 is initially turned off in the event of the impending switch-off, but instead is turned off in step S14.
  • step S16 With the opening of the mechanical switching contacts, at least one switching arc is drawn in the case of load, the time at which it occurs is recorded in step S16.
  • step S18 there is a wait until the electronically stored specified IGBT blocking time t1 is reached, for example by starting a timer that measures the time elapsed until the IGBT blocking time t1 is reached.
  • the IGBT blocking time t1 defines the burning time of the arc from the point at which it occurs.
  • step S20 the electronically stored switching number is reset to zero in step S20 and the IGBT is then switched on for a time t2 (steps S22, S24).
  • step S22, S24 the arc current is immediately commutated to the low-impedance semiconductor switch 20 or IGBT arranged parallel to the mechanical switch, where the current is very quickly reduced to zero, as in a regular switch-off process, and in step S26 the semiconductor switch 20 or IGBT is switched to blocking.
  • step S28 the number of switching operations stored is increased by 1 for each switching-off process that is carried out.
  • the increased switching number is stored again in the internal non-volatile memory.
  • step S12 If the comparison in step S12 shows that the stored number of operations is less than the setpoint number of operations, no current conditioning is required and the process continues directly with step S22.
  • the time of the commutation to the IGBT of the semiconductor switch 20, which has already been turned on, can be detected by a current transformer 60 located there.
  • the current converter 60 generates a signal as soon as a current begins to flow through the IGBTs of the semiconductor switch 20 (after the semiconductor switch 20 or IGBT has been switched on in step S22), i.e. the current flow commutes from the first mechanical contact arrangement 10 to the semiconductor switch 20.
  • the signal generated by the current converter 60 and signaling the commutation is fed to the switching electronics 50, which can control the semiconductor switch 20 as a function of this, as described below.
  • the switching electronics 50 can control the semiconductor switch 20 in such a way that the IGBTs of the semiconductor switch 20 become blocking again after a short current flow time or current conduction time t2 defined or specified via the switching electronics 50, so that the commutated load current in the semiconductor switch 20 is led to zero within the defined period of time.
  • the current flow time is ideally measured via the switching electronics 50 in such a way that the contact gap with the first and second mechanical contact arrangement 10 or 30 is completely open, i.e. the switching contacts are permanently open and any switching chatter processes no longer occur.
