Definitions
- the invention relates to a lighting system with gas discharge lamps and an autotransformer uninterrupted voltage regulation of the Gas discharge lamps.
- a street lighting system will be used during the evening rush hour generally with full Luminous intensity, i.e. operated with mains voltage, and in the quiet night time with reduced tension. With gas discharge lamps, switching from the Mains voltage to the reduced voltage and vice versa uninterrupted, otherwise the lamp will fail.
- this is stepless adjustable transformers used, e.g. B. a Autotransformer that has an iron core with only one Has winding, the input side with the phase of Network and the neutral conductor and on the output side with one Tapping the transformer winding and the neutral conductor connected is.
- the voltage to be removed is indicated by Tap the line leading to the phase of the consumer leads, obtained on a turn of the winding.
- the Ratio of the voltage to be reduced to the nominal voltage corresponds to the ratio of the number of turns, between the output side of the winding and of the stripped turn to the total number the winding of the winding.
- the entire winding forms so the primary winding, during the winding section between the tap and the neutral Secondary winding of the savings transformer forms.
- Designated load section is also called Designated load section.
- variable transformers are known in which the Winding is provided with taps. So while there is no interruption of switching and no short circuit of the turns to be switched on and off occurs in each branch between tapping and the supply line to the consumer two switching elements provided, the second switching element a Resistance bridged. The switching process begins with the fact that in the connected, first branch of the Resistor is turned on and then over an equal resistance in the other branch Connection is made with the new tap. The turns to be switched between the two Taps are now short-circuited in the Short circuit, however, are the two resistors and limit the short-circuit current. If so now first switching element is separated in the first branch, the new tap is already connected. Your direct connection to the outer supply line finally by closing the second switching element in the second branch reached.
- the well-known variable transformer with tap changer is through the two switching elements and the resistance at each tap is expensive and accordingly expensive.
- the object of the invention is a simple structure To provide lighting system with gas discharge lamps, which is an uninterrupted voltage regulation of gas discharge lamps.
- the device according to the invention is preferably used for Bridging the load section of the transformer and the other switching element, the primary winding except To put operation. It can also be in the control section be provided.
- the two Switching elements When switching to change the Voltage on the gas discharge lamps are the two Switching elements controlled so that the load section Throttle forms. In this way, the Gas discharge lamps when switching always with the Minimum voltage supplied. When switching between individual switching elements practically simultaneously takes place, the throttling effect can hardly bear come. The short circuit can then be so short that the short-circuit current cannot increase.
- the Switching elements can therefore be controlled so that a Short circuit is limited in time so that a Damage to the switching elements or lines is prevented.
- controllable transformer there is the primary and / or Secondary winding preferably at least partly from individual sections, which in one of the combination corresponding to decreasing voltage are interconnectable.
- At least one section has the first switching element in its current path and the other between its entrance and the exit Switching element on.
- the switching elements are preferred by Sagittarius formed.
- Each section can have one Resistor, a choke and / or a fuse have, preferably a line with the one Switching element is provided with which the consumer the phase of the network can be connected.
- the further Switching element can be arranged in the line, which the load section on the output side with the consumer connects.
- the transformer winding of the autotransformer has preferably one on the input side to the phase of Network and output side to the phase of the consumer connected load section and one connected on the output side to the neutral conductor Control section on, which at least partially from the Individual sections that exist in one of the combination with decreasing voltage the neutral are connectable.
- the tax section consists preferably of a first part and a second part. The second part is between the arranged first part and the load section. It is the number of turns connected to the neutral conductor of the second part unchangeable, while the number of turns of the first which can be connected to the neutral conductor Is partly changeable.
- the consumer is one Lighting system with gas discharge lamps.
- the gas discharge lamps at full light intensity So operating with mains voltage is the first Switching element closed and the second switching element open. If the Brightness reduced, that is Gear ratio of the transformer corresponding voltage drop, the first switching element opened and the second switching element getting closed. To do this is a certain one Switchover time necessary.
- the two switching elements are preferably by protection with make contacts and / or protection with make and break contacts. At protection as a switching element is the switchover time a few milliseconds.
- a switching element in the primary circuit opened So that goes the load section of the transformer, i.e. the Section over which the load current flows into a Throttle over. This way a failure of the Lamp prevented during the switching process. Then the further switching element is closed, whereby a the transformation ratio of the transformer sets the corresponding voltage drop.
- FIGS. 1 to 5 a different circuit of an autotransformer show according to the invention.
- the autotransformer consists of a closed iron core 1 with a winding 2. Die entire winding 2 forms the primary winding of the Autotransformer, section 4 of winding 2 between phase L of the network and tap 3 of the Line 5 to the gas discharge lamp 6 provides the The load section represents the load current IL to the lamp 6 flows.

- the contactor is actuated.
- the load section 4 acts during the switching time of Protection for a short time, d. H. for example 5 to 50 Milliseconds as a choke.
- the throttle leads to a voltage drop. However, this is low, so that the lamp 6 during the switching process with a sufficient voltage U2 is supplied.
- closes the switching element 9, whereby the load section 4th or bridged the choke and thus the lamp 6 with the nominal voltage U1 is operated, that is U2 U1.
- the nominal voltage z. B. is 220 V
- the reduced voltage U2 is greater is than that for operating the gas discharge lamp 6 required minimum voltage, preferably 5 V to 10 V greater than the minimum voltage to accommodate fluctuations in the Nominal voltage.
- the load section 4 is the Bridged transformer and the primary winding 2 or the control section 7 is deactivated.
- the two switching elements 9, 11 are each so controlled that the load section 4 a Gas discharge lamps 6 forms upstream choke.
- FIG. 2 shows a transformer with a primary winding 12 and a secondary winding 13 on a closed one Iron core 1 shown. Through lines 15 and 16 this transformer is also switched as an economy transformer.
- the secondary winding 13 forms the load section of the Transformer, i.e. the section over which the Load current IL flows via line 14 to lamp 6.
- the secondary winding 13 has a bypass line 8 can be bridged with a first switching element 9.
- the primary winding 12 is on the input side with the phase L of the network connected via a line 15 in which the second switching element 11 is arranged.
- the exit side the primary winding 12 is connected via a line 16 to the Neutral conductor N connected.
- the switching element 9 When the load voltage U2 to a reduced voltage U2 ⁇ U1 is to be switched, the switching element 9 first opened so that the secondary winding 13 as Throttle acts, whereupon the switching element 11 is closed becomes.
- FIG. 1 An autotransformer is shown in FIG which the load voltage U2 can be finely regulated can.
- the secondary winding 7 of Figure 1 is there replaced by a control section 17.
- the control section 17 is composed of a first part 18 and a second part 19 is formed.
- the turns of the second part 19 connect to the turns of the Load section 4.
- the turns of the first part 18 the control section 17 consist of several Sections I to IV.
- Each individual section I to IV points in its current path a first switching element 24 to 27. Furthermore, a Switching element 28 to 31 between the input side E and the output side A of each section I to IV intended. From the input side E each Section I to IV leads a line 32 to 35 to the turns of the relevant section I to IV, with the first in lines 32 to 35 Switching element 24 to 27 is arranged. Another Line 36 to 39 leads from the turns of the each individual section I to IV to the Output side A of the same.
- the input side E of the first individual section I is via a line 40 to the output side of the second Part 19 of the control section 17 connected while the output side A of the facing away from the second part 19 Section IV via a line 41 with the Neutral conductor N is connected, in line 41 that Switching element 11 is arranged.

- Each individual section I to IV has one different number of turns. For example, can the individual section I ten, the individual section II twenty, section III forty and the Individual section IV have eighty turns.
- the number of turns NM of the Control section 17, which is connected to the neutral conductor are in accordance with the voltage U2 to be taken be changed.
- the number of turns NM of the The control section consists of the unchangeable Number of turns NM const. Of the second part 19 and changeable number of turns NM v of the individual sections I to IV, which are connected to the neutral conductor N.

- the total effective winding, i.e. H. the load section 4, the second part 19 of the control section 17 with the invariable number of turns NF as well as the switched turns NR of the first part 18 of the Control section 17 form the primary winding of the Saving transformers, while the second part 19 and the switched turns NR of the first part 18 die Form secondary winding. It can be seen that with that the primary and secondary winding for the economy transformer can be changed, depending on which Section I to IV interconnected and with the Neutral conductor N are connected.
- the transformer can also be designed in three phases.
- the first switching element 24 to 27 and the second switching element 28 to 31 the individual section I until IV are closed at the same time individual sections I to IV short-circuited, so that it can be destroyed.
- switching elements 24 up to 31 can shooters, remote controlled electromagnetic switches are used that are inexpensive and millions of switches withstand.
- the two switching elements 24 and 28, 25 and 29, 26 and 30 and 27 and 31 of each section I to IV should switch on the one hand if possible, so that the twitching stops, on the other hand they are allowed not be closed at the same time because otherwise a Short circuit occurs.
- the short-circuit current however, needs a certain one Time from z. B. two to ten milliseconds until it turns fully built. Therefore, when switching elements 24 to 31 be used which have a very short switching time have, for example, a switching time that the Half or less of the build time for the Short-circuit current, there is a risk that a Short circuit to damage the concerned Section I to IV leads, significantly reduced.
- the primary winding is 12 in the same way from individual sections I to IV constructed like the first part 18 of the control section 17 of the autotransformer according to FIG. 3. Accordingly, in Figure 4 also the same reference numerals for the Switching elements 24 to 31, the lines 32 to 39 and the resistor 43 used.
- the switching element 11 is in the line 16 arranged which the output of the Individual section IV connects to the neutral conductor N. This transformer is through lines 15 and 16 also switched as an economy transformer.
- Control section 17 of the savings transformer several branches 53, 54, 55 on, which by the switching elements 50, 51, 52, preferably contactors, optionally with neutral line N are connectable.
