Definitions
- the invention relates to a liquid-cooled valve throttle, in particular for a high-voltage direct current transmission system, according to the preamble of claim 1.
- High-voltage direct current transmission (HVDC) systems are generally used today to distribute electrical energy as a link between two three-phase systems; network-controlled, controllable semiconductors convert the three-phase current on the transmitter side for transmission into direct current and on the receive side back into three-phase current.
- the highest achievable thyristor voltage is small compared to the valve voltage necessary for economical transmission.
- a large number of thyristors must therefore be connected in series for an HVDC valve.
- a valve choke with a liquid-cooled choke coil and choke core is connected in series with the individual thyristors.
- each HVDC valve consists of a larger or smaller number of identical thyristor and throttle modules, depending on the voltage to be controlled, which are grouped together like a tower in a tower base frame.
- a valve throttle known according to the preamble is known from W090 / 14674.
- the throttle core is surrounded on all sides by a noise-absorbing insulating capsule which also serves as a supporting frame and which, in turn, is wrapped around the outside by the winding of the throttle coil held on the supporting capsule.
- the choke core is made up of two U-shaped partial cores, in particular cut ribbon cores, and the insulating capsule is in accordance with the U-shaped partial cores are composed of two trouser-shaped insulating partial capsules with their open leg ends opposite one another, the waist-side openings of which can be closed by a lid after the respective insertion of the U-shaped partial cores.
- a valve throttle in particular for high-voltage direct current transmission systems, is known from EP 0 223 954 A1.
- the choke coil is potted on the winding side and the potting block thus formed is mounted in a surrounding plastic stenter via rubber buffers.
- the choke core consists of two U-shaped partial cores and is also un-potted and fastened in the clamping frame via tie rods.
- the winding is cooled by using waveguides.
- the choke core carries cooling pockets on one side for cooling.
- the entire arrangement constructed in this way is shielded by an outer insulation jacket, at least some of the connecting or connecting pieces of the coolant supply being located within the insulation jacket.
- the cores are cooled with the heat sinks attached or wrapped.
- the heat generated in the cores cannot be dissipated with high efficiency.
- the core halves are held together with tensioning straps, which are not reliable in the case of large cores, for example throttle cores, in the case of these designs. These straps must therefore be re-tightened from time to time.
- the invention is based on the object of specifying a liquid-cooled valve throttle which no longer has the disadvantages listed.
- this frame By attaching heat sinks to the free surfaces of the clamping frame of the choke core, this frame not only serves as a fastening element of the U-shaped choke partial cores, but also as a heat sink at the same time. Since the choke core has two cooling channels, the assembled choke core can be intensively cooled on two different sides. This heat sink dissipates the heat absorbed by the frame. Since liquid, in particular water, is used as the cooling medium, the heat generated in the partial cores can be dissipated with high efficiency by the liquid.
- the cores and the winding parts are mounted on a base plate, which has a distribution and a collector tube for the coolant.
- FIG. 1 illustrates a valve throttle according to the invention, in particular for a high-voltage direct current transmission system, which consists of a choke core 2, a choke coil 4, a base plate 6 and some cooling lines 8.
- the throttle core 2 of this valve throttle consists of two U-shaped throttle partial cores 10, one of which is shown in more detail in FIG.
- the valve throttle has two throttle cores 2, which are arranged spatially parallel to one another.
- These choke cores 2 are arranged on the base plate 6 in a self-supporting manner by means of buffers 12, for example vibrating metal buffers or rubber buffers.
- These buffers 12 serve not only as vibration dampers, but also as fastening means for the choke core 2.
- the choke sub-cores 10 are each provided with an insulating encapsulation 14, also referred to as a plastic shield, with two insulating encapsulations 14 of a choke core 2 at the ends of each Legs, for example by means of a shrink tube 16, are connected to each other.
- These cooling lines 8 are with the; Distribution and the manifold 18 and 20 of the base plate 6 connected, only the distribution tube 18 is shown in this illustration by means of a broken line.
- Each Pipe 18 and 20 of this base plate 6 is provided with a connection 22, to each of which a cooling line on one floor of the HVDC system can be connected.
- the inductor 4 consists of a primary winding 24, a secondary winding 26 and a secondary resistor 28.
- the primary winding 24 consists of two winding parts 30 and 32, each of which is wound and cast from a waveguide 34. Coolant flows through these waveguides 34, the winding parts 30 and 32 of the primary winding 24 being connected electrically and in a coolant manner in series.
- each winding part 30 or 32 of the primary winding 24 comprises a pair of legs of the cores 2 of the valve throttle arranged in parallel.
- the ends of the waveguide 34 of each winding 30 and 32 are each provided with an electrical connection device 36, 38 and 40, 42.
- connection device 36, 38, 40 and 42 is plate-shaped and provided with a connection 44 for receiving a cooling line 8.
- each connection device 36, ..., 42 is provided with two threaded bores.
- the two winding parts 30 and 32 of the primary winding 24 are each detachably connected to the base plate 6 with a plurality of insulating supports 46.
- the secondary winding 26 consists of only one turn and is accommodated within the winding part 30 of the primary winding 24.
- the electrical connections 48 and 50 of this secondary winding 26 are led out of the winding part 30.
- one turn of the secondary winding 26 is not closed.
- the secondary winding 26 does not consist of a waveguide 24, but can consist of a stranded wire.
- the secondary resistor 28 is connected electrically in parallel with this secondary winding 26.
- This secondary resistance 28 is cooled by liquid.
- a stainless steel tube is provided as the liquid-cooled secondary resistor 28, which is mounted on the plastic shield 14 of the cores 2 of the valve throttle and is meandered in accordance with this figure.
- the liquid-cooled secondary resistor 28 is connected to the distribution pipe 18 via a cooling line 8 and on the output side likewise via a cooling line 8 to the manifold 20 of the base plate 6.
- the secondary resistor 28 is electrically conductively connected to the electrical connections 48 and 50 of the secondary winding 26 by means of two connecting pieces 52 and 54. This secondary resistor 28 serves to increase the degree of damping of the valve throttle. As a result, the cores 2 of the throttle are relieved, so that not as much power loss in the cores 2 is converted into heat.
- FIG. 3 shows a U-shaped throttle partial core 10 and FIG. 4 shows its side view from the right in detail.
- This throttle partial core 10 is provided with a part of a clamping frame 56 which is provided on its free surface 58 with a heat sink 60.
- the heat sink 60 can also be part of a part of the tensioning frame 56.
- the heat sink 60 has at least two cooling channels 62 and 64, of which only the cooling channel 62 can be seen in this illustration.
- these cooling channels 62 and 64 are provided with connections 66 and 68 and, on the other hand, are connected to one another by means of a connecting pipe 70.
- Stainless steel bolts are provided as the inlet and outlet connections 66 and 68.
- the side 72 of the heat sink 60 facing away from the legs is provided with two threaded bores 74, into which the buffers 12, shown here as oscillating metal buffers, are screwed.
- the two parts of the tenter frame 56 are attached to the core 2 adjusted and fixed with varnish. This is done in the following way:
- the frame parts and the core 2 are clamped with releasable fastening elements (not shown) and with fastening screws, so that the frame 56 is seated on the core 2 as far as possible (core winding is relatively "soft" after the annealing process).
- the unit is then soaked in a suitable varnish under vacuum. After the paint has dried out, the fastening elements and the fastening screws are removed and the core is separated into two identical pieces (U-shaped choke partial cores 10) (cutting tape cores).
- the heat generated in the partial cores 10 is conducted by heat conduction from the clamping frame 56 to the heat sinks 60, through which cooling liquid flows, so that very intensive cooling is guaranteed.
- the cooling channels 62 and 64 of the two cooling bodies 60, each of a throttle core 2 are connected by means of cooling lines 8 to the distribution and collecting pipes 18 and 20 of the base plate 6.
- the lower and the upper heat sinks 60 of the two choke cores 2 are each connected in series by means of a cooling line 8.
- FIG. 3 The position of the insulating encapsulation 14 of a choke partial core 10 is indicated in FIG. 3 by means of a broken line.
- FIG. 5 shows a section through this insulating encapsulation 14, the illustration of the choke partial core 10 being omitted for the sake of clarity.
- the position of the partial throttle core 10 is only indicated by a broken line.
- the plastic shield 14 of a choke partial core 10 consists of two parts 76 and 78. These two parts 76 and 78 of the insulating encapsulation 14 are hooked together. Part 78 forms the outer peripheral side wall the insulating encapsulation 14.
- This plastic shield 14 is held at a distance by elastic spacers 80 from the side walls of the throttle core 10.
- the noise level of the partial core 10 is damped by means of this plastic shield 14.
- This configuration provides a liquid-cooled valve throttle, in particular for a high-voltage direct current transmission system, the cores 2 of which are arranged in a self-supporting manner and the heat generated in these cores 2 can be dissipated with high efficiency by coolant.
