Abstract
1399681 Transformers MASCHINENFABRIK REINHAUSEN Gebr SCHEUBECK KG 19 June 1973 [20 June 1972] 28982/73 Heading HIT A transformer on-load tap-changing arrangement comprises output means L 1 -L 2 connectable to each of two input connections U 1 , U 2 through a main path I, II comprising at least two switches in series I 1 -I 2 II 1 -II 2 , and an auxiliary path III, IV comprising at least two switches in series III 1 -III 2 , IV 1 , IV 2 . Between two switches in each auxiliary path III, IV there is connected a switchover resistance R 1 , R 2 comprising at least two resistors in series R 11 -R 12 , R 21 -R 22 ; and from the respective junction of each of these pairs a high resistance R 4 , R 5 is connected to the junction of two switches in the respective associated main switch path I, II. A further high resistance R 3 is connected between the two auxiliary switching paths III, IV in such a way as to be connectable to each input connection U 1 , U 2 through a respective one of the switch means III 2 , IV 2 of each auxiliary switching path. In the tap-changing sequence, e.g. from main path I to main path II, make-before-break switching occurs in the order I-III, III-IV, IV-II; any arc is self-extinguished at the first zero current passage after the opening of a switch. Each of the switchover resistances R 1 , R 2 is designed to drop a potential difference at nominal load current equal to the step voltage (U 2 -U 1 ); and each resistor R 11 ; R 12 , R 21 , R 22 is made equal to one-half its respective switchover resistance; in this way the recovery volrages of the switches in any path are made equal in magnitude. Where tap-changing has to be done under overload conditions, a further division of the swirchover resistances is made Fig. 6, so that the resistor R 2 is connected to the switches III 2 IV 2 through resistors R 13 , R 23 , which modify the distribution of recovery voltage among the switches of the auxiliary paths III, IV.
