Definitions
- the invention is based on a switching point of a high or Medium-voltage switch according to the preamble of claim 1.
- a switching point of the type mentioned above is described in EP 0 147 036.
- One on one bridge contact piece fastened electrically conductive disc closes two fixed contact pieces in the closed state of the switching point short.
- a flat coil is attached to both sides of the disc such that the disc can be moved between the two coils by means of electrodynamic forces, which causes the bridge contactor to short circuit between the fixed Cancels switching pieces, or restores them.
- a current is fed into the first coil, which is in the disc causes an eddy current opposite to the current in the coil.
- the both currents have a repulsive effect on one another, which causes the movable disc removed from the fixed coil and the bridge contact cancels the short circuit between the fixed contact pieces.
- a current is in the second coil fed.
- the object of the invention is as set out in the claims based on specifying a switching point of the type mentioned, which quickly and can be opened and closed with little energy.
- the switching point according to the invention is axially symmetrical. This succeeds it to largely avoid undesirable leakage inductances, which is particularly the case with any commutation of the current on a parallel path is advantageous.
- the for Formation of the forces of an electrodynamic contact drive necessary Induction current is in the nominal current-carrying, movable bridge contact generated, whereby an otherwise usually provided disc-shaped part for Guiding the induction current and thus additional mass to be accelerated can be saved.
- the required to achieve a certain opening or the closing speed of the switching point minimizes the drive energy required.
- opening there are also two contact gaps, each of one of two partial arcs connected in series are bridged. Through this series connection of Partial arcs increase the falling at a contact arrangement of the switching point Arc voltage, which in turn is particularly useful in the event of a parallel path can be commutated quickly and effectively.
- Fig. 1 shows a contact arrangement of the switching point according to the invention in the closed Status.
- a nominal current IN flows in from a first connection 11 fixed contact 1, a movable, designed as a contact ring 3 Bridge contact and a fixed contact 2 to a second Connection 21.
- the fixed contact 1 is designed as a disc and from surround the fixed contact piece 2, which is substantially cylindrical is trained.
- the two fixed contact pieces 1, which are coaxially interlocked and 2 and the contact ring 3 fitted between them together form the Contact arrangement.
- the contact arrangement is made of an electrically insulating Contact carrier 7 worn. As can be seen from Fig. 2, the circular ring 3 in move in the axial direction.
- the contact arrangement can be opened and the Rated current IN can be interrupted.
- To drive the contact ring 3 contains the Switching point an electrodynamic drive, with two ring-shaped, flat coils 5 and 6.
- the two coils 5 and 6 delimit one in the axial direction Annulus 8, in which the circular ring 3 moves back and forth.
- the annular space 8 is delimited by an insulating body 4 which also has the coil 6 wearing.
- the exact geometric design of the contact arrangement can be seen in FIG. 3.
- the two fixed contact pieces 1 and 2 form a gap 81.
- This gap is so wide that in the closed state of the switching point the contact ring 3 fits exactly and has good electrical contact on both sides with the fixed contact pieces 1 and 2.
- the contact pieces 1 and 2 are provided with contact fingers K against the gap 81.
- the contact fingers K are separated from one another by slots L and have a low spring action in the radial direction. As a result, the mechanical hold of the contact ring 3 in the gap 81 and the electrical contact are improved.
- the first coil 5, which is required for opening the contact arrangement, is attached below the gap 81.
- the contact ring 3 is located at the other end of the annular space 8, in a holding device 10, the task of which is to hold the contact ring 3.
- the second coil 6, which is required for closing the contact arrangement, is attached above the holding device 10.
- the insulating body 4 is pressure-resistant and is gas-tightly attached to the fixed contact pieces 1 and 2.
- the annular space 8 has a region 82 which is widened in the radial direction between the gap 81 and the holding device 10.
- the annular space 8 is filled with a gaseous medium, for example air or SF 6 under atmospheric or higher pressure.
- the two coils 5 and 6 are fed by a power electronic control unit 9.
- 3 and 4 show a first embodiment of the control unit 9 of the switching point according to the invention.
- a first capacitor C S and two thyristors T S1 and T S2 with antiparallel connected freewheeling diodes D S2 and D S1 are connected to coil 6 to form a first circuit.
- a second capacitor C O and two further thyristors T O1 and T O2 with antiparallel switched freewheeling diodes D O2 and D O1 with the coil 5 are connected to a second resonant circuit.
- the functioning of the drive of the switching point is explained on the basis of a closing process, as is shown in FIG. 3.
- the contact ring 3 is located in the holding device 10, the capacitor C S is positively charged and the two thyristors T S1 and T S2 are blocked.
- the capacitor C S is discharged via T S1 , the coil 6 and the freewheeling diode D S1 .
- the result is a sinusoidal current pulse I S in the drive coil 6, which causes an eddy current I W in the contact ring 3 directly below it.
- the drive current Is and the eddy current I W have opposite directions, which results in a repulsive effect Fs between the contact ring 3 and coil 6.
- the coil 6 is firmly connected to the insulating body 4.
- the contact ring 3 is accelerated downwards and is only dampened when it enters the gap 81 by an air cushion enclosed in the gap 81 and by friction. When it hits the coil 5 underneath it, it is finally braked.
- the capacitor C S forms a series resonant circuit with the coil 6. A one-time firing of the thyristor T S1 thus results in the capacitor C S swinging over.
- the capacitor C S is now negatively charged with a voltage slightly lower than the original voltage, since the ohmic resistors in the circuit result in electrical losses.
- the thyristor T S2 is ignited, with which the capacitor C S is recharged a second time via T S2 , the coil 6 and the free-wheeling diode D S2 . Due to the greater distance between the contact ring 3 and the coil 6, there is now a smaller force pulse F S on the contact ring. However, this is sufficient to prevent the ring from rebounding from the fully closed position.
- the successive firing of the thyristors T S1 and T S2 has the essential advantage that the fixed contact pieces 1 and 2 do not have to be dimensioned according to the braking force on the contact ring 3 during the closing process.
- the contact ring 3 only has to have sufficient kinetic energy to reach the completely closed position against the friction of the fixed contact pieces 1 and 2. Bouncing back from there is not possible due to the second power surge that follows.
- the second triggering also has the advantage that the capacitor C S swings around again and is therefore positively charged again.
- a charging device that can only generate positive charging voltages can now be switched on again directly in order to recharge the capacitor C S. Because of the residual charge voltage already present, this recharging process will also be significantly faster than a recharging process. For applications in which repeated triggering is required, the charging device can thus be made smaller.
- An opening process corresponds essentially to the closing process.
- the contact ring 3 is located in the gap 81, the capacitor C O is positively charged and the two thyristors T O1 and T O2 are blocked.
- the capacitor C O is discharged via T O1 (T O2 ), the coil 5 and the freewheeling diode D O1 (D O2 ).
- the current in turn causes an eddy current in the contact ring 3, which is then accelerated in the axial direction and detached from the fixed contact pieces 1 and 2 to form two partial arcs connected in series.
- the contact ring 3 moves in the annular space 8 in the axial direction and is only delayed again by the holding device 10.
- the holding device 10 is designed in the form of a narrowing of the annular space 8.
- the contact ring is completely braked and held in place by friction.
- the slots L in the fixed contact pieces 1 and 2 prevent eddy current formation in the fixed contact pieces 1 and 2.
- the slots L run away from the gap 81 in the radial direction and have a length of about 1 cm.
- the drive is based on both the closing process and the opening process the principle of electrodynamic repulsion. It is particularly advantageous that only the contact ring 3 is moved mechanically. No further is needed moving parts for power transmission, triggering or energy storage.
- the Electrodynamic drive also has the advantages of exact triggerability Ignition of a thyristor, the short-term, fast-acting and very high Impulse force and the uniform force effect on the contact ring. Thanks to the axially symmetrical design of the contact arrangement of the switching point according to the Invention is the contact ring 3 without mechanical guide elements by the expanded area 82 of the annular space 8 out.
- the holding device with the conical extending constriction 10 at the upper end of the annulus 8 and conical bevelled, fixed contact pieces 1 and 2 at the lower end of the Annulus 8 inherently center the contact ring 3.
- the inner geometry of the annular space 8 can be used to advantage Contact ring 3 to delay during the opening process or in order Annulus 8 a suitable flow of the gaseous medium present there to reach. This is vital when the contact ring 3 becomes one Loses contact time at which the nominal current IN is not zero. Also at The existence of a low-impedance and low-inductance parallel path will increase Commutation arcs between the fixed contact pieces 1 and 2 and form the contact ring 3, which by the flow in the annular space 8 and through the insulating body 4 are cooled. This has a higher arc voltage Consequence, which in turn accelerates the commutation process.
- the geometric mass of the contact arrangement of the switching point according to the invention depend on the nominal electrical data of the switching point. At a nominal current IN the switching point of 5 kA and a nominal voltage of 12 kV is the Diameter of the contact ring 3 approx. 250 mm. Its the width of the gap 81 corresponding thickness is 8 mm. At a height of a few millimeters, it's over silver-plated aluminum built contact ring 3 a mass of some 10 to 100 gram. The switching time for a switching point of this size is approx. 1 ms per Switching operation.
