1471739 Transformers and inductors TRANSFORMATOREN UNION AG 3 June 1974 [4 June 1973] 24395/74 Heading HIT Voltage surges in transformer or inductor windings 27-30 are controlled by a capacitor bank comprising a plurality of disc coils A-D, each disc coil comprising spiral wound conductors 40, 41 with their inner ends open circuit, the disc coils being magnetically uncoupled with the windings, each winding having a capacitor connected in parallel and all the capacitors being connected in series. A bank of capacitors (54, Fig. 3, not shown) may be arranged in the space between two parallel connected transformer windings each comprising four pancake coils (57-60 and 61- 64 respectively) and the conductor pairs (69, 70 and 71, 72) forming capacitors each of which is associated with a pancake coil at the same potential are interwound into one disc coil (65). Fur the surge control of a fine stage winding comprising 6 winding stages in each of two parallel branches the number of capacitors is equal to the number of fine stages and the series connections between the capacitors are electrically connected to corresponding connections between the fine stages (Fig. 2, not shown). |
