Definitions

  • the invention relates to a high-voltage switching device with series connection of at least two vacuum interrupters according to the preamble of claim 1 and to a method for operating the high-voltage switching device.
  • the invention can be used for example in gas-insulated switchgear.
  • high voltage is the voltage range above 1000 V understood.
  • Vacuum interrupters are used in traction power supply with one frequency of 16 2/3 Hz. In comparison to the arc times occurring at 50 Hz / 60 Hz of 10 ms / 8.3 ms the contact distances at 16 2/3 Hz are also used Arc times of 30 ms.
  • the associated comparatively high thermal stress and the resulting greatly increased burn-up leads to a large reduction the dielectric strength when switched off. You counteract this effect that for rated voltages of e.g. 17.5 kV two vacuum interrupters switched in series and additionally taxed capacitively.
  • the invention has for its object a high-voltage switching device with series connection of at least two vacuum interrupters of the type mentioned to be specified which can be optimally utilized with regard to the voltage load.
  • the measures listed are intended to ensure that the row arrangement of each depending on geometry, application and environmental conditions To compensate for influences on the switch-off behavior without using outside Control capacitors rigidly need to control.
  • This task is related to the high-voltage switching device in connection with the Features of the preamble according to the invention by the in the characterizing part of the claim 1 specified features solved.
  • the task is related to the method for operating the high-voltage switching device solved by the features specified in claim 6.
  • the advantages that can be achieved with the invention are, in particular, that the voltage distribution on the basis of a natural, exclusively by own and Stray capacities affected voltage distribution and without additional control capacities is achieved. This eliminates the need to re-ignite and re-ignite a vacuum interrupter equalization currents that arise and flow through the control capacities, whose amplitudes increase with increasing control capacity, so lead to heating of the contact pieces of the vacuum interrupters and finally reduce the breaking capacity.
  • a particular advantage is the ability to master the task Switching cases (short-circuit breaking capacity, switching capacity) independent of the Task to master the dielectric requirements through a suitable choice of To be able to solve vacuum interrupters.
  • the arc behavior can be reduced by additional measures on the drive unit are directly influenced and thus enables the introduction of a separate degree of freedom to interpret both the dielectric behavior and the switch-off behavior in the event of an arc.
  • the proposed measures lead by combining different vacuum interrupters with different sizes (different nominal voltage, different Breaking current) and / or different contact piece design (different contact piece diameter, different contact distance of the Contact pieces, different contact piece types) and generally different Own capacities for different arcing behavior.
  • This effect is the variety of designs for mastering the individual switching cases in the Compared to known arrangements significantly increased.
  • a high-voltage switchgear has two main tasks. On the one hand, it has to withstand the dielectric stresses when the contact pieces are open, on the other hand it has to master the thermal and mechanical effects when a short-circuit arc is switched off and, after this short-circuit current has been successfully extinguished, withstand the recurring voltage in the form of a transient settling process.
  • the associated period extends over a few 100 microseconds and, in the case of a series arrangement, is demonstrably characterized by the choice of the capacitive circuitry and the plasma processes inside the switching chamber.
  • a targeted influence on the transient processes that follow after the end of the arc period is to be achieved by different design of the vacuum interrupters and the contact pieces, by measures on the drive and by using different arc characteristics.
  • the ability of a series connection should be particularly exploited so that in the event of re-ignition of a switching chamber, the non-affected switching chamber can take over the entire voltage stress. This is referred to below as the takeover process and represents a particular advantage for capacitive switching for mastering reignitions.
  • FIG. 1 is a schematic diagram of the series connection of vacuum interrupters for High-voltage switching devices shown using the example of a switch pole.
  • a first vacuum interrupter 1 and a second vacuum interrupter 2 are in series between a high-voltage connection 3 and an earth connection 4.
  • the self-capacitance CE1 of the first vacuum interrupter 1 is in series with the parallel circuit formed from the self-capacitance CE2 of the second vacuum interrupter 2 and the stray capacitance Cst.
  • the invention is based on the principle of a row arrangement of two or more different vacuum interrupters 1, 2 as the heart of a high-voltage switching device.
  • By using different types of vacuum interrupters within A switch pole can have both its own capacities and its arcing behavior of the two different vacuum interrupters in terms of Voltage stress and the extinguishing capacity of the series arrangement in advantageous Ways can be combined.
  • a special feature of the invention is the configuration of the first vacuum interrupter chamber 1 on the high-voltage connection 3 with a larger contact piece diameter and thus an increased capacitance CE1.
  • the second vacuum interrupter chamber 2 connected to the earth-side connection 4 has a comparatively smaller contact piece diameter with a correspondingly comparatively lower intrinsic capacitance CE2, but in the installed state it is supplemented by the stray capacitance Cst effective against earth potential. With a suitable choice of the vacuum interrupter types, this influence of the stray capacitances can therefore be minimized or completely eliminated.
  • the condition for this is: CE1 ⁇ CE2 + Cst.
  • Another advantage of the series arrangement of at least two vacuum interrupters 1, 2 is that re-ignition of a vacuum interrupter is not inevitable leads to re-ignition of the entire switch pole. This is due to the reignition time advanced dielectric strength of the unaffected switching chamber attributed. Especially in the case of capacitive switching, Because of the suitable selection of the different vacuum interrupters connected in series the optimized ability to take over tension.
  • a different arc behavior can be caused by opening the Contact pieces of at least two vacuum shading chambers are forced.
  • a series connection consisting of two vacuum interrupters can both the contact pieces of the upper vacuum interrupter chamber 1 and those of the lower vacuum interrupter chamber 2 opened with a time delay.
  • staggered entry and exit Switching off the vacuum interrupters 1, 2 results in a desired manner targeted distribution of the switching stress on both vacuum interrupters, expressed due to this measure on the respective vacuum interrupter adjusting portion of the voltage recurring after a shaving action.
  • the vacuum interrupters are switched on and off at different times 1, 2 the stress distribution in the case of pure dielectric stresses be influenced in the desired favorable manner.
  • Fig. 3 there is a voltage / time diagram to explain the phenomenon of a Voltage transfer through a vacuum interrupter during re-ignition the further vacuum interrupter shown. It is the course of the transient voltages U to recognize depending on the time t. At time 0 it continues successful arc quenching recurring mains voltage in the form of a transient Transient voltage U3. The dotted line divides above the row arrangement total transient voltage U3 shown so that a dash-dotted line Partial transient voltage U1 and partial transient voltage U2 (solid Line) arises. At time t1, reignition occurs at the first (upper) Vacuum interrupter 1. The second (lower) vacuum interrupter 2 takes over this time t1 the total stress, i. H. the at this time effective total transient voltage U3. Then the upper one solidifies Vacuum interrupter 1 and can again be a small part of the total voltage Take over U3.
  • the switch-off behavior of the series connection can take into account the potential distribution attributed to the singular behavior of the individual vacuum interrupters become.
  • the potential division is in the first microseconds of the transient voltage due to effects of the after-current arc through ohmic (Plasma) resistors determine the process of reconsolidation within describe the switching distance. After a few microseconds, this plasma resistance already grown so much that the intrinsic and stray capacities split the voltage determine over both switching distances.
  • the tension distribution will by the stray capacitance Cst of the (lower) vacuum interrupter 2 against earth influenced, d. H. the spreading capacity east works in the sense of a pre-control (however without the disadvantages explained above).
